6:20 pm EDT: The launch was scrubbed at about 15 minutes before liftoff time due to violations of weather constraints. The clouds were starting to clear but not in time for the instantaneous launch window.
The next launch opportunity is on Saturday at 3:22 p.m. EDT (19:22 UTC). Followed by Sunday, May 31 at 3:00 p.m. EDT (19:00 UTC).
2:01 pm EDT: The launch of a SpaceX Falcon 9 with astronauts Bob Behnken and Doug Hurley in a Dragon spacecraft to the International Space Station is set for 4:33 pm (EDT) today at Kennedy Space Center . The weather forecast currently gives a 50% chance of acceptable conditions for liftoff from Pad 39A during the instantaneous launch window. (There are also storms along the US East Coast where the capsule would need to land in an abort.) If they don’t get off the ground today, the next opportunities will be on Saturday and Sunday.
SpaceX and NASA are providing joint continuous coverage of the preparations for the liftoff:

** SpaceX Demo-2: Watch NASA astronauts launch to space for the first time on Crew Dragon – NASASpaceflight.com
I had the opportunity to meet up with SpaceX CEO, Founder and Chief Engineer, Elon Musk as well as NASA Administrator, Jim Bridenstine to get their thoughts on this new era of human spaceflight! We spoke in the historic Firing Room 4 at Kennedy Space Center where SpaceX will command the rocket to launch for Demonstration Mission 2 with Bob Behnken and Doug Hurley!
** SpaceX Demonstration Mission-1 Highlights – NASA – An uncrewed Dragon was launched to the ISS on March 2, 2019
Demonstration Mission-1 (Demo-1) was an uncrewed flight test designed to demonstrate a new commercial capability developed under NASA’s Commercial Crew Program. The mission began March 2, when the Crew Dragon launched from NASA’s Kennedy Space Center in Florida, and racked up a number of “firsts” in less than a week. First commercially-built and operated American crew spacecraft and rocket to launch from American soil on a mission to the space station. First commercially-built and operated American crew spacecraft to dock with the space station. First autonomous docking of a U.S. spacecraft to the International Space Station. First use of a new, global design standard for the adapters that connect the space station and Crew Dragon, and also will be used for the Orion spacecraft for NASA’s future mission to the Moon. NASA and SpaceX teams gathered in the early morning hours at the company’s headquarters in Hawthorne, California, to follow the spacecraft’s return journey and ocean splashdown.
** Final reviews and preparations underway for first crewed Dragon mission to the ISS. On Friday, the joint NASA/SpaceX Flight Readiness Review (FRR) gave the Demonstration Mission-2 (DM-2) a Gofor liftoff next Wednesday. And a couple of hours later, SpaceX carried out a successful static test firing at Pad 39A of the Falcon 9’s booster engines. A “dry dress rehearsal” today will have the crew in full flight suits board the capsule and go through all activities short of firing the engines.
The liftoff is set for 4:33 pm EDT on May 27th. This is an instantaneous window so any problems during the countdown will lead to a delay of the launch. The next available launch opportunities are on Saturday, May 30 at 3:22 p.m. EDT (19:22 UTC) and on Sunday, May 31 at 3:00 p.m. EDT (19:00 UTC).
Weather looks to be a major factor since not only does the weather at the Cape need to be acceptable, but it must also be acceptable at 50 points along the ground track from the Cape to West Europe where the Dragon could land if there is an in-flight abort. The current weather forecast (pdf) from the USAF Weather Squadron at Patrick AFB gives only a 40% chance of acceptable conditions at the Cape for liftoff on Wednesday.
We are extremely excited to announce that the window for our Launch Demo mission starts on Sunday, May 24th, and extends through Monday, May 25th, with an opportunity to launch from 10 A.M. – 2 P.M. Pacific (17:00 – 21:00 GMT) each day.
That means that this weekend, our 747 carrier aircraft Cosmic Girl will prepare to take off from Mojave Air and Space Port, fly out over the Pacific ocean, and release our two-stage, orbital rocket, LauncherOne — which will then proceed to ignite its engine in mid-air for the first time.
This Launch Demo marks the apex of a five-year-long development program. On our journey to open up space for everyone we’ve conducted hundreds of hotfires of our engines and our rocket stages, performed two dozen test flights with our carrier aircraft, and conducted countless other tests of every bit of the system we could test on the ground.
Launching from the Earth to space is mind-bogglingly difficult. Thousands of components all need to function as planned while controlling high energy and flying at incredibly fast speeds. The vehicle’s structures must be robust enough to tolerate traveling at up to 18,000 mph without disintegrating; the temperatures and pressures of its propellants can’t be too high or too low; every internal valve must click open and closed in perfect synchronicity… There’s a long list of factors that need to line up in order to make it all the way. We’re mindful of the fact that for the governments and companies who have preceded us in developing spaceflight systems, maiden flights have statistically ended in failure about half of the time.
In the future, the goal of our launches will be to deploy satellites for a new generation of space-based services. For this Launch Demo, though, our goal is to safely learn as much as possible and prove out the LauncherOne system we’ve worked so hard to design, build, test and operate.
The instant our Newton Three engine ignites, we will have done something no one has ever done before — lighting an orbital-class, liquid-fueled, horizontally-launched vehicle in flight. Once we reach an altitude of 50 miles it will be the first time this kind of launch system will have ever done so.
We’ll continue the mission for as long as we can. The longer LauncherOne flies, the more data we’ll be able to collect. Should we defy the historical odds and become one of those exceedingly rare teams to complete a mission on first attempt, we will deploy a test payload into an orbit, take our data, and then quickly de-orbit so as not to clutter the heavens.
Scott Manley gives his preview of the test:
Virgin Orbit have announced their first test launch is targeted for Sunday May 24th, they’ll attempt to launch their Launcher One rocket into orbit from the Cosmic Girl carrier aircraft. The launch will occur over the Pacific ocean west of Southern California. It’s the first time a cryogenically fueled air launched orbital rocket has been attempted, so it’ll be fascinating to see whether all the engineering, planning, testing and rehearsals will reward the company with a successful launch on their first attempt. Most rockets fail on their first attempt, and since this is doing a number of new things the team are prepared to accept even a partial success as a win.

The ninth and final flight of Japan’s H-2B rocket — the country’s most powerful launcher — drove an automated cargo freighter into orbit Wednesday on a five-day pursuit of the International Space Station.
The 186-foot-tall (56.6-meter) launcher lifted off from the Tanegashima Space Center in southern Japan at 1731 GMT (1:31 p.m. EDT) Wednesday, sending an HTV supply ship into space with 2.5 million pounds of thrust from four solid rocket boosters and two hydrogen-fueled core engines.
Wednesday’s launch was the last in a series of nine H-2B rockets, and also marked the ninth and final flight of Japan’s current-generation barrel-shaped HTV cargo carriers. Japan is developing a more capable supply freighter named the HTV-X, which will deliver heavier payloads to the space station.
The HTV-X is scheduled for its first flight to the space station in 2022, and it’s designed to eventually fly supplies to the planned Gateway mini-space station in orbit around the moon.
The H-2B and the less powerful H-2A rocket will be replaced by a new, less expensive Japanese launcher named the H3, which will launch the HTV-X missions. MHI and the Japan Aerospace Exploration Agency, or JAXA, are jointly developing the H3 rocket, which could be ready for an inaugural test flight before the end of 2020.
On its USSF-7 flight, the X-37B is expected to demonstrate new capabilities – including flying with the service module for the first time. This module, which is attached to the aft end of the spacecraft, hosting additional equipment and experiments for the mission. Ahead of launch Barbara Barrett, the Secretary of the Air Force, stated that this mission would carry out more experiments than any previous OTV flight. The X-37B spacecraft incorporates a payload bay that can be opened in orbit to expose experiments to space. A solar panel, deployed from the bay, provides power to the spacecraft and its experiments.
During the course of its mission, X-37B will deploy the small FalconSAT-8 satellite for the US Air Force Academy. The latest in a series of experimental satellites built by the Academy for technology demonstration and to give cadets experience constructing and operating spacecraft. FalconSAT-8 carries eight experiments. Two of these are being carried on behalf of NASA, investigating the effects of the space environment and radiation on material samples in one experiment, and on seeds in the other. FalconSAT will also conduct an experiment for the Naval Research Laboratory to investigate wireless power transfer, generating electrical power through the satellite’s solar panels and transmitting it to the ground as microwave radiation.
—- Atlas V USSF-7 Launch Highlights – United Launch Alliance (ULA)
A United Launch Alliance (ULA) Atlas V rocket carrying the USSF-7 mission for the U.S. Space Force lifted off from Space Launch Complex-41 on May 17 at 9:14 a.m. EDT. This marks the 84th successful launch of an Atlas V rocket, 139th launch for ULA, the second launch for the U.S. Space Force and the sixth flight of the X-37B Orbital Test Vehicle (OTV-6).
Edinburgh, Scotland, 20 May 2020 – The UK’s Space race heats up as Skyrora effectively made the UK ready for launching rockets into space after a team successfully built a mobile launch complex and completed a full static fire test with the Skylark L rocket on it – in only five days. Skyrora’s combined achievement also signifies the first vertical static fire test of this magnitude in the UK since the Black Arrow Programme, 50 years ago. The Skylark L rocket could be ready to launch from a British spaceport as early as spring 2021 and the inaugural launch of the low Earth orbital (LEO) Skyrora XL rocket by 2023.
The ground test at the mobile launch complex at Kildemorie Estate in North Scotland earlier this month, saw Skyrora’s launch vehicle, Skylark L perform all actions of a launch while restrained to the ground and prevented from taking off.
Skylark L is a bi-liquid propellent launch vehicle. It is Skyrora’s first sub-orbital flight vehicle, ready to reach a height of approximately 100km, just on the Karman line, and carry a payload of up to 60kg. Skylark L uses a propellent combination of Hydrogen Peroxide and Kerosene which are pressure fed into a Skyrora 30kN engine. Building up to the static fire test, the rocket engine itself has gone through three hot fire tests before integration into the vehicle. When commercial, the company plans to use their own Ecosene, an equivalent Kerosene fuel made from un-recyclable plastic waste. In Skyrora’s rocket suite, its aim is to start with launching sub-orbital rockets and move to orbital by 2023.
The full static firing test, fully checked out the design and in-house manufacture, making sure the vehicle itself is ready for launch. It was also successful in the feed system validation tests leading up to the full static fire test. During the test, Skylark L was supported by Skyrora’s transporter-erector that was fixed to the trailer.
In order to complete this test, the Skyrora team accomplished the build of a mobile launch complex in record time right in the heart of the Scottish Highlands.
The mobile complex was made up of several modules including, a command centre, oxidiser and fuel handing containers and a compressed gas container. During the test, the Bells and Two Tones Fire and Rescue team were onsite ready to perform any necessary procedures if anything was to go wrong.
Leading the operations of Skylark L’s static fire testing, Dr Jack-James Marlow said: “It is very hard to oversell what we have achieved here with this test; the whole team has pulled through again to deliver another UK first. We have successfully static tested a fully integrated, sub-orbital Skylark L launch vehicle in flight configuration. This means we performed all actions of a launch but did not release the vehicle. The rocket engine successfully burned, with all vehicle systems showing nominal operation.
We are unbelievably proud to announce that we have successfully completed the UK’s first ground rocket test in 50 years. We have successfully completed a full static fire test at our mobile launch complex in five days.

The burst pressurization tests helped the company verify its ambitious 3D-printing approach to building rockets, as well as the materials it’s using. Ellis said the tank burst at about “10% more than the requirements with the safety factor” needed for a launch.
“It’s definitely sufficient for the whole launch vehicle,” Ellis said, adding that “we’ve got two years to keep making it better.”
Here is a Bloomberg interview with Rocket Lab CEO Peter Beck:
*** Skyroot Aerospace is an Indian startup launch services company. The Vikram Launch Vehicles will provide increasing orbital payload capabilities. The Vikram I rocket will use solid fueled motors to put 225 kg into 500 km orbits.
In my view, space is a sector with clear achievable objectives for the decades to come like more launches, rapid re-usability to enable satellite constellations and human space travel. To me the biggest barrier to all space activities is ‘speed’ or rapid developmental cycles. At Skyroot, that is exactly what we are building a culture around –rapid development of complex aerospace systems with lean use of resources. We are building the first private Indian launch vehicle to put a satellite in orbit and marching ahead to compete for a reasonable share in the international small satellite launch market which is estimated to be $16Bn in the next decade. hiCompleting seven months of advanced development, we are building an ecosystem of quick development of aerospace systems in speeds never imagined before. The idea of Skyroot was born from the need of having an internationally competent company with the capability of complementing ISRO’s capacity to meet our nations Space aspirations. hiIn this process, we are taking baby steps into our eventual goal of pushing the boundaries of spaceflight to uplift our civilization out into the cosmos.
Rocket Crafters, the first space launch company to use additive manufacturing to 3D print rocket fuel, announces the conclusion of testing for the Comet engine, a large-scale proof of concept test model of its STAR-3DTM hybrid rocket engine. The tests were designed to show that the patent-pending hybrid rocket engines could scale from the laboratory to a size more commercially relevant. With 49 successful laboratory tests under their belt ranging from 250 to 500 pounds of thrust, Rocket Crafters initiated testing of the Comet 5000-pound thrust engine in February of this year.
Comet was tested three times. The first two tests were successful, closely matching the performance models that Rocket Crafters created. While still considered successful in terms of research and development, the third test experienced an overpressure anomaly, resulting in damage to the test stand and test engine. After the anomaly, the Rocket Crafters engineering team dug deep into the hardware and recorded data to determine what had occurred and how to prevent it in future tests. After extensive analysis, it was concluded that there was an initial failure in an ancillary part of the engine. This led to a larger over-pressurization inside the combustion chamber. The team found no problems within the core STAR-3DTM engine design.
“This is why we test,” said Rocket Crafters President, Robert Fabian, a twenty-five-year veteran of military space and missile operations and maintenance. “We find and fix problems in testing, so we don’t have them on the launch pad. We’re moving forward from here.”
With the completion of the large-scale proof of concept testing, Rocket Crafters is taking their lessons learned and applying them to their next big project- a test flight powered by a smaller version of the STAR-3DTM hybrid rocket engine. This will be Rocket Crafters’ inaugural launch of a flight engine and the first opportunity to see the performance in motion rather than bolted to a test stand. Rocket Crafters has planned two more consecutively larger test flights into space and back to Earth, and then into orbit. Not long after that, commercial service to Low Earth Orbit with the Intrepid small satellite launch vehicle will begin.

—- Plasma Engine for Space Cargo Trucks – The SX3 AF-MPD Thruster:
The future of space is here, and it’s electric! Watch the SX3 in action – an Applied-field Magentoplasmadynamic thruster (or AF-MPD for short) that’s unlocking the future of spaceflight. This type of plasma propulsion uses strong magnetic and electric fields to produce thrust, which is why it’s best suited for high-power applications (think space exploration, or even cargo transfer to the Moon and Mars!).
Developed at the Institute for Space Systems (IRS) at the University of Stuttgart, it’s the most advanced AF-MPD prototype in the world. Here, it’s running on Argon (that’s why it’s blue), but it can also work on many other propellants like Krypton, Ammonia and Hydrogen. This versatility is what gives it huge economic and technological advantages compared to competing technologies.
So far, the SX3 has achieved ground-breaking thrust efficiencies (as high as 63%) and steady-state operation of several hours. This is thanks to the world class professors, researchers, testing facilities, and simulation capabilities at the university.

**** Next Starlink mission delayed till after the DM-2 crew launch. The one day slip of the Atlas V launch of the X-37B last weekend bumped the Falcon 9 launch of 60 more Starlink satellites by a day but then stormy seas made a landing of the booster impossible. So the launch was postponed till after the crew mission.
“SpaceX is offering pricing that previously wasn’t really seen,” said Mike Safyan, vice president of launch at Planet, an Earth imaging company with more than 150 small satellites in orbit.
Planet announced last week that it will launch six SkySat satellites as rideshare payloads on SpaceX rockets scheduled to launch Starlink broadband satellites. Two sets of three SkySats will ride in separate Starlink missions to low Earth orbit
The rideshare program is “incredibly competitive,” Safyan told SpaceNews. He called it “one of the more significant programs for the smallsat industry especially because of the pricing, the reliability and the number of orbits.”
****** Fire broke out on the SN4 prototype Starship following a Raptor engine test last week at the Boca Chica Beach facility on May 19th. The engine firing itself seemed to go well but the plume set off a couple of small fires along the base of the vehicle. One of the fires appeared to be fed by insulation wrapping on the launch stand’s metal structure and was put out fairly quickly. Another fire flared near a small pipe that connected into the base of the vehicle. Don’t know if this line contained methane fuel or hydraulic fluid to control the engine. Whatever was flowing in it, the crew appeared to have little or no control over a valve to shut it off. It took probably 15-20 minutes to put out the fire completely with a remotely controlled water hose. Several times it seemed to be snuffed out, only to flare up again. The flames appeared to damage cables going up the side of the vehicle.
Usually after a test, the road by the launch pad area is reopened and a group of techs and engineers soon arrive in a fleet of vehicles to resume work on the vehicle. This time, however, the road remained closed for over a day and no one other than a drone approached the vehicle. Though there had been forceful venting from the liquid methane and oxygen tanks following the engine firing, some hazardous fluids and/or gases must have remained in the vehicle. Perhaps damage from the fire had severed the control room’s connections to the valves and sensors needed to fully safe the vehicle after the test. There was no statement released by the SpaceX team at Boca Chica or by Elon Musk explaining what was going on with the vehicle.
There were times during the continuous live video of the vehicle through the rest of the day and night when one could see some vapor emitted near the base of the vehicle. It was perhaps this additional venting that eventually made the vehicle safe enough to approach. By the afternoon of the 20th, the road was finally opened and techs arrived to begin working on the vehicle,. It seems the damages were not too serious since SpaceX has scheduled further testing at the site. This presumably includes another static firing and then a short hop flight.
New Boca Chica road closures on May 28, 29, and June 1 from 6 am to 2 pm local time.
Looks like Starship SN4 will be ok for more testing! Expecting the possibility of another static fire test before the hop though.https://t.co/2oKOYZetSp
With the impending hop of SpaceX’s Starship SN4 and its continuing successful tests, I wanted to show how they got to where they are in just over 1 year. After the successful 150 meter flight of Starhoper in August of 2019 SpaceX went all in on development of the Starship spacecraft and us rocket fans couldn’t be happier. These are very simplified animations of what basically occurred with each test article.
Speculation time! This is my simplified animation on how SN4 might look on its first flight, landing legs and all. With the single Raptor engine mounted in its place off center, it will need to balance its center of gravity with a bit of tilt. In reality it will land on an adjacent cement landing pad, but for animation reasons I had it land next to the test stand. Enjoy!
**** While SN4 was struggling to get off the Boca Chica launch pad, assembly of more Starship prototypes continued in the manufacturing area. Here are some videos over the past several days showing the work on SN5 and SN6.

**** SpaceX Crew Dragon Demo 2 Launch this Week, SpaceX Starship News, X-37B military space plane 2020 – Marcus House
The SpaceX Crew Dragon Demo 2 Launch this Week, SpaceX Starship News and the X-37B military space plane 2020 launched. There is certainly no shortage of news and updates in the space industry since the last video. It’s been another interesting week with SpaceX’s Starship prototype developments with the SN4 breathing fire again with both a pre-burner test and a static fire leading up shortly to that 150-meter flight. The SN5 and SN6 are both being stacked together in the high bay which is a first to see so we’ll dive into all that. We had the amazing X-37B launch on the Atlas V with a bunch of new experiments. The incredible upcoming Crew Dragon mission which will fly Astronauts Bob and Doug is now potentially only days away assuming no delays. This is, of course, the first flight with Crew from the United States for almost a decade. This is going to be a huge week.
In this Episode, we will take a look at the recent Static Fire and analyze, what happened. We will also take a look at a Starship Taco Dome, Serial Number 5s Nose Cone, Starship heat tiles and last but not least, we will take a look at the Artemis progress. How far are NASAs SLS, Orion and the Lunar Gateway?
**** Saturday, May 16th, a ULA Atlas V rocket will take a X-37B spaceplane into orbit for the 6th mission of the program. (See previous ST Roundup for info on the X-37B mission.) The window for the launch is between 8:24-10:53 am EDT (1224-1453 GMT).
**** Sunday, May 17th, a SpaceX Falcon 9 will put 60 more Starlink satellites into orbit. Over 400 Starlink satellite are already in space. Liftoff is set for 0753 GMT (3:53 a.m. EDT). A storm brewing in the Atlantic, however, may cause a postponement since it could prevent the recovery of the booster, which will be on its 5th flight. To maintain the desired high flight rate for the Starlink program, the boosters need to be reused multiple times. A test firing of the booster engines was successfully carried out yesterday.

Planet is set to launch six more SkySat satellites (SkySats 16-21) into Low Earth Orbit this summer, rounding out the fleet of 15 SkySats already in operation.
SkySats 1-15 operate in Sun Synchronous Orbits, a specific type of Low Earth Orbit that results in the Earth’s surface always being illuminated by the Sun at the same angle when the satellite is capturing imagery. About half of the SkySats currently pass overhead in a morning crossing plane, while the other half moves in an afternoon crossing plane, so together they provide twice-daily coverage of select areas on a global scale. SkySats 16-21 will operate at a “mid-inclination” orbit of 53 degrees, complimenting the Sun Synchronous fleet, and will offer more targeted coverage and raw image capacity in key geographic regions.
The six SkySats will be evenly split across two launches on SpaceX’s Falcon 9, a two-stage reusable rocket that has successfully flown satellites and cargo over 80 times to orbit. They will do so as rideshare payloads on launches of SpaceX’s Starlink satellites.
SkySats 16-18 will launch on SpaceX’s ninth Starlink mission, targeted for launch in the next month, and SkySats 19-21 will launch later this summer. Both missions will launch from Cape Canaveral Air Force Base in Florida.
The launch of SkySats 16-21, as well as the development of our enhanced 50 cm imagery (to be made available to customers this year)—are just some examples of Planet’s continuously evolving industry-leading geospatial offerings. Stay tuned to the Pulse blog for more launch and product updates in the coming months.
Elon Musk has noted that progress in any given technology is simply # of iterations * progress between iterations. SpaceX has successfully completed six major iterations and is on its seventh rocket version iteration. SpaceX has existed for eighteen years and has shortened its development time from six years to about two years.
This is why SpaceX is crushing all of its competitors like United Launch Alliance, China, Russia, Ariane and Blue Origin.
****** SpaceX continues to maintain a very high level of activity at Boca Chica Beach. The Raptor engine used during test firings last week was removed from the SN4 Starship prototype. A subsequent pressure test on the SN4 using cryogenic propellants successfully reached 7.5 atmospheres, which should provide sufficient margin for uncrewed test flights. (8.5 atm will need to be reached to provide the safety margin desired for crew flights.) A different Raptor engine was then installed on SN4. Test firings are expected to start within a day or two. If these go well, there could be a 150 meter hop a few days after that.
This diagram for the cryogenic tank tests shows the liquid methane fuel in green and the liquid oxygen in blue:
Let’s clear some misconceptions:
chilly exterior: cold(er than air) gas inside
chilly with condensation on bottom: very little cryo liquid inside (common before static fires)
frosty walls: filled with cryo liquid (up to the frost lines. happens during cryo proof and actual WDRs) pic.twitter.com/Fz3seKp3mW
Components for SN6 are also in production. Each prototype is expected to have improvements and enhancements over the previous one. Eventually, a SN# will go to orbit and then attempt a reentry and landing.
Here are Elon’s goals for transport costs once operational Starships are flying:
Starship + Super Heavy propellant mass is 4800 tons (78% O2 & 22% CH4). I think we can get propellant cost down to ~$100/ton in volume, so ~$500k/flight. With high flight rate, probably below $1.5M fully burdened cost for 150 tons to orbit or ~$10/kg.
SpaceX successfully static fired their Starship SN-4 prototype using fuel from the header tank (secondary smaller tank inside the main tank). Everything looked good and SpaceX will continue to push to prepare for the 150m hop of this vehicle. Thanks to Rachel and Gene from @SPadre [@ spacepadreisle on twitter] for shooting this for us!

** SpaceX test fired the Raptor engine on the SN4 Starship prototype on two consecutive days. On Tuesday evening, a Raptor engine fired for the first time while mounted on a full scale Starship. Previous Starship prototypes did not survive propellant tank pressure testing. On Wednesday, another brief firing took place. No word from SpaceX or Elon Musk yet on whether more engine tests are planned or if they will proceed towards a 150 meter hop. Higher altitude flights will wait for the SN5 or later model prototypes.

** China’s new Long March 5B heavy lift rocket successfully launched on its first attempt. The vehicle, powered by a liquid-fuel core first stage and four liquid-fueled side boosters, lifted off from the Wenchang Spaceflight Launch Center on the southern island of Hainan. The primary payload was a prototype of a new crew vehicle design that will replace the Shenzhou spacecraft that were used for several crew missions. A reentry operation from a high orbit is expected on Friday, which will send the reusable capsule to a remote northern desert area for a landing by parachute. The fast reentry will put the heat shield under stresses and temperatures similar to that of a return from the Moon. The LM-5B will be the primary launch system for China’s crew program, which include the launch of a space station in the coming years. The country’s first Mars rover will also be launched this July on a LM-5B.
Virgin Orbit could attempt its first orbital test launch later this month over the Pacific Ocean southwest of Los Angeles, capping a development program for an air-launched small satellite carrier that began in earnest eight years ago.
The small satellite launch company, part of Richard Branson’s Virgin Group, entered the final phase of pre-flight testing last week with a ground fueling test of its first flight-worthy LauncherOne rocket.
Dan Hart, Virgin Orbit’s CEO, said the company is on track for the rocket’s first demonstration launch in May.
The LauncherOne rocket is designed to compete with other commercial smallsat launchers, such as Rocket Lab’s Electron booster, for contracts to deliver CubeSats and microsatellites to orbit for commercial customers, the U.S. military and NASA. Virgin Orbit says it can haul up to 660 pounds (300 kilograms) of cargo into a 310-mile-high (500-kilometer) polar sun-synchronous orbit, a standard operating orbit for Earth-imaging satellites.
It’s been humbling to see LauncherOne take shape over time as our team meticulously works through these increasingly complex engineering challenges. Last week’s LOX wet dress rehearsal was beautifully executed, so we’ll continue to move with gusto toward our Launch Demo. 🚀 pic.twitter.com/aR69A1jtFU
A Space Act Agreement (SAA) between NASA, Virgin Galactic and The Spaceship Company (TSC) has been announced, raising the hope that spacecraft could one day become a future high-speed civilian transportation system. Utilizing the “Point-To-Point” method, Virgin Galactic – and as previously envisioned by SpaceX – is aiming for a transportation option that would vastly reduce transit times.
The SAA is aimed at “advancing the United States’ efforts to produce technically feasible, high Mach vehicles for potential civil applications,” noted the text of the agreement.
This will be the first X-37B mission to use a service module to host experiments. The service module is an attachment to the aft of the vehicle that allows additional experimental payload capability to be carried to orbit.
“This sixth mission is a big step for the X-37B program,” said Mr. Randy Walden, Director and Program Executive Officer for the Department of the Air Force Rapid Capabilities Office. “This will be the first X-37B mission to use a service module to host experiments. The incorporation of a service module on this mission enables us to continue to expand the capabilities of the spacecraft and host more experiments than any of the previous missions.”
The mission will deploy the FalconSat-8, a small satellite developed by the U.S. Air Force Academy and sponsored by the Air Force Research Laboratory to conduct several experiments on orbit. The FalconSat-8 is an educational platform that will carry five experimental payloads for USAFA to operate. In addition, two National Aeronautics and Space Administration experiments will be included to study the results of radiation and other space effects on a materials sample plate and seeds used to grow food. Finally, the U.S. Naval Research Laboratory, will transform solar power into radio frequency microwave energy which could then be transmitted to the ground.
“We are excited to return the X-37B to space and conduct numerous on-orbit experiments for both the Air Force and its mission partners,” said Lt. Col. Jonathan Keen, the X-37B program manager.
The X-37B program completed its fifth mission in October 2019, landing after 780 days on orbit, extending the total number of days spent on orbit for the spacecraft to 2,865 – or seven years and 10 months.
Nearly three months after delivering several tons of supplies and scientific experiments to the International Space Station, Northrup Grumman’s unpiloted Cygnus cargo craft is scheduled to depart the International Space Station on Monday, May 11.
Live coverage of the spacecraft’s release will air on NASA Television and the agency’s website beginning at 11:45 a.m. EDT, with release scheduled for noon.
Dubbed the “SS Robert H. Lawrence,” Cygnus arrived at the station Feb. 18 with supplies and science experiments following its launch on Northrup Grumman’s Antares rocket from NASA’s Wallops Flight Facility on Wallops Island, Virginia.
Flight controllers on the ground will send commands to robotically detach Cygnus from the Earth-facing port of the Unity module, maneuver it into place, and release it from the Canadarm2 robotic arm. Station commander Christopher Cassidy of NASA will monitor Cygnus’ systems as it moves away from the orbiting laboratory.
Within 24 hours of its release, Cygnus will begin its secondary mission, hosting the Spacecraft Fire Safety Experiment – IV (Saffire-IV), which provides an environment to safely study fire in microgravity. It also will deploy a series of payloads. Northrop Grumman flight controllers in Dulles, Virginia, will initiate Cygnus’ deorbit to burn up in Earth’s atmosphere Monday, May 25.
Blue Origin has been making significant progress on the structures, systems, propulsion, and infrastructure supporting their New Glenn heavy lift rocket. Though the company is traditionally quite secretive about most of their operations, they have recently been revealing more and more information as they work towards a first flight date of no earlier than 2021. They also won through as part of the Human Landing System (HLS) award winners as its goals move from the suborbital, through to Low Earth Orbit and beyond.
The company expects to deliver two “flight readiness” BE-4 engines to ULA this summer. These two engines will be attached to a Vulcan rocket for a hot-fire at SLC-41.
And here is a bit of info on the status of the suborbital New Shepard:
Despite COVID-19 and a lack of public activity, I’m hearing that Blue Origin is still targeting a New Shepard flight with humans before the end of 2020. What is taking so long? They’re addressing a lot of little issues to ensure the safety of the vehicle. No word on prices yet.
… Dave was asked a few questions about the corporation Masten Space Systems. Dave talked about employees, hiring new employees from engineering disciplines but not specifically aerospace engineers, plus he talked about their expected growth over the next 5-10 years. I asked Dave how he got his interest in lunar landers \. He said it started early on, around 2004. Don’t miss Dave’s story. Ft. Worth John then called to ask questions about the green fuel plus he wanted specific impulse information for their rocket engines. After this call, Dr. Lurio called to ask Dave about the additional mass for the XL-1 lander over and above the NASA payload requirement of 80kg. Dave was also asked about having made structural changes to the XL-1 to add the additional payload mass. Don’t miss this discussion. …

SpaceX’s next Starlink satellite launch has slipped about a week and a half into mid-May, placing it just nine days (or less) prior to the company’s inaugural NASA astronaut mission.
Known as Crew Dragon’s second Demonstration Mission (Demo-2), SpaceX’s first astronaut launch is officially scheduled no earlier than May 27th and is with little doubt the most important mission in the company’s history. Simultaneously, however, SpaceX is working to rapidly launch thousands of Starlink satellites in a bid to deliver high-quality internet service to tens – or even hundreds – of millions of people. The company has already launched an incredibly 420 operational Starlink satellites but that’s just a drop in the bucket compared to the ~4400, ~12,000, or even ~40,000+ the company will ultimately need to match its ambitions.
****** In addition to the firing of the Raptor engine on the SN4 prototype mentioned at top, there is a great deal of production activity underway at Boca Chica Beach. The SN5 prototype is nearly completed and construction of SN6 has begun. Unlike SN4, these will have conical nosecones stacked on top since they will need aerodynamic shapes to carry out high-altitude flights. Here is a diagram showing the estimated assembly status of SN5 and SN6:

**** SpaceX Starship Updates – Static Fire! – Crew Dragon Demo Mission 2 Update – What about it!?
In this Episode, we will take a look at the intense testing operations at the SpaceX Launch Site in Boca Chica Texas. Static fires, methane flares and Starship SN5 & 6 construction. We will also take a look at the recent NASA press conference regarding the SpaceX Demo Mission 2. We will take a look at trainings, Bob Behnken and Doug Hurley had to go through, last minute Crew Dragon preparations and the latest news on parachute tests.
NASA has selected three U.S. companies to design and develop human landing systems (HLS) for the agency’s Artemis program, one of which will land the first woman and next man on the surface of the Moon by 2024. NASA is on track for sustainable human exploration of the Moon for the first time in history.
The general plan is for an HLS system to operate initially with the Orion spacecraft launched by a SLS. with astronauts on board. Later, the lander will dock to the Gateway station in high lunar orbit.
For these three HLS (Human Landing Systems) program contracts,
NASA’s commercial partners will refine their lander concepts through the contract base period ending in February 2021. During that time, the agency will evaluate which of the contractors will perform initial demonstration missions. NASA will later select firms for development and maturation of sustainable lander systems followed by sustainable demonstration missions. NASA intends to procure transportation to the lunar surface as commercial space transportation services after these demonstrations are complete. During each phase of development, NASA and its partners will use critical lessons from earlier phases to hone the final concepts that will be used for future lunar commercial services.
Here is an audio recording of the teleconference on April 30th in which the announcement was made:
Blue Origin National Team (incl Blue, Lockheed Martin, Northrop Grumman, and Draper)
$579M for further design work on the “Integrated Lunar Vehicle” (ILV), a 3 stage system that includes a transfer stage to power the system from the Gateway station or Orion in high lunar orbit to low lunar orbit, a lander stage, and an ascent stage. Each of the ILV stages will launch on either a Blue Origin New Glenn rocket or a ULA Vulcan and then be assembled in orbit.
$253M for design of a 2-stage modular system for descent and ascent. The modules will launch separately on ULA Vulcan rockets.
There would be two propellant modules ( Modular Propellant Vehicles or MPVs) and one crew module (called the Descent/Ascent Element or DAE). The propellant modules, or “drop tanks” would be discarded during the descent to the lunar surface after the propellants were consumed.
The Dynetics Human Landing System concept includes a single element providing the ascent and descent capabilities, with multiple modular propellant vehicles prepositioned to fuel the engines at different points in the mission. The crew cabin sits low to the surface, enabling a short climb for astronauts entering, exiting, or transporting tools and samples. The DHLS systems supports both docking with Orion and with Gateway, and will get a fuel top-off before descending to the surface. After the surface expedition, the entire vehicle will return for crew transfer back to Orion.
$135M for design of a Starship customized for transport between lunar orbit and the surface. Other Starships will support the lunar vehicle’s mission. Reusable Super Heavy boosters will send Starships into earth orbit.
The Lunar Starship has no thermal protection or reentry control surfaces as it will be used only for going back and forth between lunar orbit and the lunar surface.
The Lunar Starship will initially rendezvous in earth orbit with another Starship that will provide propellants to power the trip to the Moon. Other Starships will supply propellants to this depot Starship.
After refilling its tanks, the lunar Starship will go to lunar orbit. When NASA’s Gateway station is orbiting the Moon, the SpaceX Starship will dock with it.
A problem with the standard Starship design for lunar missions is that the powerful Raptor engines would make deep craters in the surface while landing and taking off. Some of the dust and small rocks from the blast could even be accelerated into orbit due to the Moon’s low gravity and become hazardous debris for spacecraft there. The images of the Lunar Starship show thruster ports just above the mid-line of the vehicle. Presumably, these propulsion units provide sufficient thrust for landing while generating plumes that mostly disperse by the time they reach the ground and avoid the cratering and debris problems.
Starship is a fully reusable launch and landing system designed for travel to the Moon, Mars, and other destinations. The system leans on the company’s tested Raptor engines and flight heritage of the Falcon and Dragon vehicles. Starship includes a spacious cabin and two airlocks for astronaut moonwalks.

The primary goal of the test flight is testing the Long March 5B for launching to low Earth orbit (LEO). If successful, launch of the ‘Tianhe’ core module for China’s space station could take place as soon as early 2021.
The payload for the test launch—a prototype new-generation crewed spacecraft—will be loaded with nearly 10 tons of propellant. This will both make the spacecraft analogous to a 20-ton-plus space station module and allow the prototype to reach higher orbits and test a high-speed reentry.
Rocket Lab, a space technology company and the global leader in dedicated small satellite launch, has rolled an Electron launch vehicle out to the Launch Complex 2 pad at the Mid-Atlantic Regional Spaceport in Wallops, Virginia for the first time. The milestone is one of the final steps ahead of Rocket Lab’s first launch from Launch Complex 2 – a dedicated mission in partnership with the Department of Defense’s Space Test Program and the Space and Missile Systems Center’s Small Launch and Targets Division.
Rocket Lab engineers and technicians carried out a range of successful integrated systems tests to verify launch systems on Electron and on the ground systems at Launch Complex 2. The critical checks included raising Electron vertical on the Launch Complex 2 pad for the first time, activating and tuning pad fluid systems, power and communication checkouts as well as RF testing with the range. The test campaign concluded with a hot ignition test of the nine Rutherford engines on Electron’s first stage.
The STP-27RM mission will launch a single micro-sat from the Air Force Research Laboratory’s Monolith program, which is designed to determine the ability of small satellites to support large aperture payloads to monitor space weather. The mission is being coordinated by the U.S. Space Force’s Space and Missile Systems Center and is scheduled to launch no earlier than the third quarter of 2020.

** SpaceX releases new video of in-flight abort test:
On Sunday, January 19, SpaceX successfully completed an in-flight test of Crew Dragon’s launch escape capabilities from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. This test, which did not have NASA astronauts onboard the spacecraft, demonstrated Crew Dragon’s ability to reliably carry crew to safety in the unlikely event of an emergency on ascent.
Falcon 9 and Dragon lifted off at 10:30 a.m. EST, or 15:30 UTC, with the abort sequence initiating approximately one and a half minutes into flight. Crew Dragon’s eight SuperDraco engines powered the spacecraft away from Falcon 9 at speeds of over 400 mph. Following separation, Dragon’s trunk was released and the spacecraft’s parachutes were deployed, first the two drogue parachutes followed by the four upgraded Mark III parachutes. Dragon safely splashed down in the Atlantic Ocean and teams successfully recovered the spacecraft onto SpaceX’s recovery vessel.
** Preparations underway for first operational Dragon crew mission (Crew-1) set for the fall:

The U.S. Space Force expects to complete design validation on SpaceX’s Falcon Heavy rocket by July, ahead of the launch of the military’s first high-priority national security mission on the heavy-lifter late this year.
The launch of multiple military payloads to an orbit more than 20,000 miles above Earth will mark the fourth flight of a SpaceX Falcon Heavy rocket, the most powerful launcher currently flying anywhere in the world.
The mission is designated USSF-44, renamed from AFSPC-44 after the establishment of the U.S. Space Force in December.
SpaceX won a military contract in February 2019 to launch the USSF-44 mission from pad 39A at NASA’s Kennedy Space Center in Florida. In documents published by the military during the procurement process, the Space and Missile Systems Center, or SMC — then part of the Air Force — suggested the USSF-44 launch will loft two payloads into a circular geosynchronous orbit more than 22,000 miles above the equator.
****** The SN4 prototype is sitting on the launch pedestal and has had a single Raptor engine installed. A static firing test is expected sometime in the next few days. A brief hop to 150 meters or so should then follow within a few days after that.
Meanwhile, the sections of the SN5 prototype appear nearly complete and ready for stacking. This vehicle will probably also have two wing-like control surfaces attached. The first test flight is expected to go to around 20 km.
**** Daily video reports on activities at Boca Chica:
