** NASA and SpaceX set target date of May 27th for first launch of astronauts to the ISS on a Crew Dragon vehicle:

A new era of human spaceflight is set to begin as American astronauts once again launch on an American rocket from American soil to the International Space Station as part of NASA’s Commercial Crew Program. NASA astronauts Robert Behnken and Douglas Hurley will fly on SpaceX’s Crew Dragon spacecraft, lifting off on a Falcon 9 rocket at 4:32 p.m. EDT on May 27, from Launch Complex 39A in Florida, for an extended stay at the space station for the Demo-2 mission. The specific duration of the mission is to be determined.

As the final flight test for SpaceX, this mission will validate the company’s crew transportation system, including the launch pad, rocket, spacecraft, and operational capabilities. This also will be the first time NASA astronauts will test the spacecraft systems in orbit.

“The SpaceX Crew Dragon spacecraft undergoes final processing at Cape Canaveral Air Force Station, Florida, in preparation for the Demo-2 launch with NASA astronauts Bob Behnken and Doug Hurley to the International Space Station for NASA’s Commercial Crew Program. Crew Dragon will carry Behnken and Hurley atop a Falcon 9 rocket, returning crew launches to the space station from U.S. soil for the first time since the Space Shuttle Program ended in 2011.” Credit: SpaceX

** Northrop Grumman MEV-1 module provides station-keeping propulsion for an Intelsat satellite in geostationary orbit. The satellite is out of propellants for its own propulsion system so the MEV-1 attached itself to the satellites nozzle and will control it for about 5 years. Today the satellite was officially returned to full operation. Intelsat 901 Satellite Returns to Service Using Northrop Grumman’s Mission Extension Vehicle | Northrop Grumman

Intelsat (NYSE: I) today announced that Intelsat 901 has returned to service following the successful docking with the first Mission Extension Vehicle (MEV-1) from Northrop Grumman Corporation (NYSE: NOC) and the company’s wholly-owned subsidiary, SpaceLogistics LLC, on February 25 – the first time that two commercial spacecraft docked in geostationary orbit.

Since the February rendezvous, MEV-1 has assumed navigation of the combined spacecraft stack reducing its inclination by 1.6° and relocating IS-901 to its new orbital location. Intelsat then transitioned roughly 30 of its commercial and government customers to the satellite on April 2. The transition of service took approximately six hours. IS-901 is now operating at the 332.5°E orbital slot and providing full service to Intelsat customers.

Intelsat views life-extension services, like MEV technology, as a cost-effective and efficient way to minimize service disruptions, enhance the overall flexibility of its satellite fleet and better support the evolving needs of its customers.

Space transport roundup – Feb.26.2020

A sampling of recent articles, videos, and images dealing with space transport (find previous roundups here):

** First orbital Astra orbital rocket launch is currently set for liftoff from the Pacific Spaceport Complex – Alaska (PSCA) on Kodiak Island during the window 3:30-6:30 pm EST ( 2030-2330 GMT)on February 27th: Astra, DARPA prepare for upcoming launch challenge –

Thursday’s launch will be the third for Astra, coming after two launches in July and November 2018. Both launched from the PSCA in Alaska. These were originally believed to be failures. However, Astra stated that the first was successful, and the second was only “shorter than planned”. Neither were designed to reach orbit, as they didn’t have functioning second stages.

The company was known for operating in almost complete secrecy. Very little was known about their rockets, tests, and launch attempts. The only public sighting of an Astra rocket was by a news helicopter in early 2018. Their first rocket, named “Rocket 1.0”, was spotted being readied for a test at the former Naval Air Station Alameda in Alameda, California – just down the street from their factory.

However, Astra recently came out of the shadows, and has released some information about their operations.

Their current rocket, named “Rocket 3.0”, is a two-stage, five-engine, kerosene and liquid oxygen-powered rocket. The pumps of the first stage engines are powered by electric motors, similar to the Rutherford engines on Rocket Lab’s Electron rocket.

A DARPA video about Astra:

More about Astra‘s rockets from Scott Manley:

About 18 Months ago I covered Astra, a small rocket startup based only a few miles from my home. They were still a ‘Stealth’ company, and would not publicly acknowledge what they were doing, even after a pair of suborbital tests which failed due to engine problems. However they’re now speaking publicly, and making a lot of noise about their smallsat launcher and their first orbital launch attempt only a few days from now.

** SpaceX sets March 6th for Falcon 9 launch of Cargo Dragon mission CRS-20:

SpaceX is now targeting March 6 at 11:50 p.m. EST for launch of its 20th commercial resupply services mission (CRS-20) to the International Space Station. During standard preflight inspections, SpaceX identified a valve motor on the second stage engine behaving not as expected and determined the safest and most expedient path to launch is to utilize the next second stage in line that was already at the Cape and ready for flight. The new second stage has already completed the same preflight inspections with all hardware behaving as expected. The updated target launch date provides the time required to complete preflight integration and final checkouts.

The cargo Dragon will lift off atop a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida carrying more than 5,600 pounds of science investigations and cargo to the station, including research on particle foam manufacturing, water droplet formation, the human intestine and other cutting-edge investigations.

** Soyuz 2-1a rocket launches Meridian M satellite from the Plesetsk cosmodrome on Feb. 20th: Soyuz 2-1a launches ninth Meridian satellite –

Russia’s Soyuz-2-1a rocket made its first launch of 2020 on Thursday, carrying the ninth Meridian communications satellite into orbit. Having lifted off from the Plesetsk Cosmodrome in northern Russia at 08:24 UTC, Soyuz deployed its Fregat-M upper stage about nine minutes later to carry the satellite to its final elliptical orbit. Spacecraft separation occurred two hours and twenty minutes after launch.

Meridian is a network of satellites that provide the Russian Government with communications for military and installations in the country’s far northern regions. The Meridian constellation forms part of Russia’s Integrated Satellite Communications System, complimenting the geostationary Globus – or Raduga – series of communications satellites.

** China launches four technology demonstrator satellites on Long March-2D rocket: Long March-2D conducts maiden launch from Xichang with four satellites –

Taking precautions with the coronavirus outbreak in all orbital and space launch centers, China returned to its launch activities after the Chinese New Year festivities with a new launch from the Xichang Satellite Launch Center.

This was the first use of a Long March-2D (Chang Zheng-2D) launch vehicle from Xichang. The mission orbited four satellites that will be used to carry out inter-satellite link networking and new ground observation technology tests in orbit. The launch took place from the LC3 Launch Complex at 21:07UTC.

Named Xinjishu Shiyan-C to F, XJS-C and D were made by SAST, XJS-E by the Harbin Inst of Tech. and XJS-F by CAST’s DFH Satellite Co., Ltd. (DFHSat).

** PLD Space of Spain carries out full duration test firing of the TEPREL-B engine for the MIURA 1 suborbital rocket. PLD Space successfully achieved a full rocket engine test for MIURA 1 mission – PLD Space

In May 2019 PLD Space suffered a catastrophic engine failure, which provoked material damage, including the loss of the first flight version of the TEPREL-B liquid rocket engine, developed by PLD Space for MIURA 1 launch vehicle. Therefore, the company decided to pause the qualification process and analyse the root causes of the failure to solve the problems found.

After eight months of hard work, PLD Space successfully achieved a full mission duration hot test of the flight engine. This allowed the company to validate the nominal engine performance during the full mission duration burn of two minutes, the necessary time to boost MIURA 1 launch vehicle into space.

“This milestone is a huge step forward for PLD Space, for the Spanish space sector and the European small launcher competitiveness, and allow us to be one of the few companies in the world that has successfully developed, tested and qualified propulsion technologies for space launch vehicles. Achieving this important milestone implies a turning point in the commercial space race and take us a step closer for launching MIURA 1 into space. With this result, PLD Space has a rocket engine capable of reaching space soon”, Raúl Torres, CEO and co-founder of PLD Space.

** Venture Orbital Systems of Europe aims to launch the small Zephyr orbital rocket up to 40 times per year. First flight is targeted for 2024:

An article about Venture Orbita: CubeSat Market, The Zephyr is Positioned – Space Chronicle (Google Translate):

To start its activity, Venture Orbital needs an initial fundraising of 2.5 million euros. Depending on the information available, Zephyr can launch a payload of 35 kg in sun synchronous orbit (SSO) and 40 kg in low orbit (LEO) at an altitude of 500 km. This represents approximately the equivalent of three 6 U satellites. The launcher is ideal for placing small payloads into orbit intended in particular for Earth observation (EO), crop improvement, studying climate change or to improve access to emergency services in the event of crises. The company is not afraid to display its ambitions and has set itself the goal of arriving at up to 40 launches per year from the Guyana Space Center (CSG). The small structure also aims to offer its future availability of the Zephyr in a range of times ranging from three to six months. Launch price: around 1 million euros per mission. The company announces that it already has several contacts.

** An update on Indian reusable space transport development: A Deep Dive Into ISRO’s Reusable Launch Vehicle Technology – Part I | Delhi Defence Review

The Indian Space Research Organization (ISRO) has long sought to lower the cost of access to space. In keeping with this goal, ISRO embarked on the Reusable Launch Vehicle-Technology Demonstration (RLV-TD) Program more than decade ago. As part of the RLV-TD program, it has been developing various technologies that will serve as building blocks for a future Two-stage-to-orbit (TSTO) reusable launch vehicle. Importantly, these technologies are being developed in phases through a series of experimental flights. While the first flight of the RLV-TD, dubbed the ‘hypersonic flight experiment’ (HEX), was successfully executed on May 23, 2016, the stage is now set for the return flight experiment (REX) and scramjet propulsion experiment (SPEX) missions, respectively. LEX, in particular, is expected to be performed in the coming months.

** Upcoming Falcon 9 launch from Cape Canaveral to send Argentine satellite into a polar orbitSpaceX sets date for first Florida launch of its kind in more than half a century – Teslarati

Argentinian space agency CONAE says that both its SAOCOM 1B satellite and SpaceX are on track for a type of launch that the United States’ East Coast hasn’t supported in more than half a century.

CONAE has revealed that SpaceX aims to launch the ~2800 kg (6200 lb) radar Earth observation satellite into orbit on a Falcon 9 rocket as early as March 30th, 2020 – late next month. With such a light payload, the Falcon 9 booster – presumably reused – will be able to perform a Return to Launch Site (RTLS) recovery, touching down at one of SpaceX’s two Landing Zone (LZ) pads located at Cape Canaveral Air Force Station (CCAFS). While Landing Zone rocket recoveries have become increasingly rare for SpaceX, that’s not actually why the SAOCOM 1B mission is so unique.

Instead, it’s exceptional because it will be the United States’ first East Coast polar launch in nearly six decades. The mission’s “polar” launch profile refers to the fact that the Argentinian radar satellite will ultimately orbit Earth’s poles, effectively perpendicular to more common equatorial orbits. If successful and repeatable, the mission could ultimately spark a new era for CCAFS and Kennedy Space Center (KSC) and raises big questions about the future of California’s Vandenberg Air Force Base (VAFB) — or at least SpaceX’s presence there.

[Update 23:00 EST: The OneWeb satellites were successfully deployed into the target orbits: OneWeb successfully launches 34 more satellites into orbit | OneWeb

OneWeb, the global communications company with a mission to bring connectivity to everyone everywhere, today announced the successful launch of 34 satellites, aboard a Soyuz launch vehicle from the historic Baikonur Cosmodrome, Kazakhstan.

Lift-off occurred on February 06th at 21:42 pm UTC. The OneWeb satellites separated from the rocket and were dispensed in nine batches over a period of several hours.

This launch is the second successful launch in one of the largest civilian satellite launch campaigns in history. It will help build OneWeb’s phase one constellation of 648 satellites that will deliver high-speed, low-latency global connectivity, while addressing the world’s most pressing connectivity problems.

The communications company is on schedule to provide global coverage to customers in 2021, starting with the first commercial services in the Arctic this year. This follows OneWeb both securing global priority spectrum rights and successfully launching its first batch of satellites in 2019.

OneWeb’s network will provide a unique combination of high data throughput, low latency, true global coverage and a range of user terminals for multiple markets including maritime, aviation, government and enterprise.

Update 19:06 EST: The Soyuz launch of the OneWeb satellites reached orbit successfully this afternoon (US Eastern time). The Fregat-M upper stage is currently carrying out a series of burns that will culminate in the release of the satellites starting at around 20:30 this evening.:

Although the launch is on a Russian rocket from the famous Baikonur Cosmodrome in Kazakhstan, the launch is considered an Arianespace operation due to the collaboration with the Euro-Russian Starsem company. Starsem also launches Soyuz rockets from the Arianespace facility in Kourou, French Guiana.

More about the launch and OneWeb:

*** Transport from space to East Russia took place today as well with the return of a Soyuz capsule from the ISS with NASA astronaut Christina Koch, European astronaut Luca Parmitano, and Aleksandr Skvortsov. Koch set “a record for the longest single spaceflight in history by a woman”.

** Rocket Lab successfully launches first Electron mission of 2020:

In addition to the successful placement of the NRO satellite into orbit, additional progress was made towards the goal of recovering and reusing the Electron first stage:

The re-entry test for ‘Birds of a Feather’ is the second time Rocket Lab has guided an Electron first stage booster down to sea-level, following on from the first successful re-entry test conducted on the ‘Running Out of Fingers’ mission in December 2019. Once again, initial analysis shows the stage made it back to sea-level intact following a guided descent, proving that Electron can withstand the immense heat and forces generated on re-entry.

To guide the stage to a planned splashdown, Electron’s first stage was equipped with on-board guidance and navigation hardware, including S-band telemetry and onboard flight computer systems. The stage was also equipped with a reaction control system to orient the booster 180-degrees for its descent and keep it dynamically stable for the re-entry.

** Update on PLD Space of Spain: PLD Space books first suborbital flight, nears resolution of engine setback –

Spanish launch startup PLD Space says [it has] secured a second customer for the maiden flight of its Miura 1 reusable suborbital rocket while tackling development issues that prevented the mission from occurring last year.

Pablo Gallego Sanmiguel, PLD Space’s senior vice president of sales and customers, said Embry-Riddle Aeronautical University in Florida will fly four student- and faculty-built experiments on Muira 1. Those payloads take the remaining commercial space on the mission, which will also fly two microgravity experiments for the Bremen, Germany-based Center of Applied Space Technology and Microgravity, also known as ZARM. Half the rocket’s payload space will carry sensors to study its first flight. 

PLD Space planned to launch Miura 1 in 2019, but delayed the rocket’s debut after a “series of test firing anomalies” during engine development, Gallego Sanmiguel said by email.

The purposes of Earth’s Space Elevators are to 1) deliver cargo to the Enterprises assembling along the geosynchronous belt near the Space Elevator’s GEO Regions; and 2) support interplanetary flights from the APEX Regions; to the Moon, to Mars, and elsewhere.

Since the interplanetary flights from the Apex will use the latent ΔV, (derived from Earth’s rotation – transformed into radial speed at departure from the Apex); Space Elevators are established around the Solar System as part of the Galactic Harbour transportation network. Elevators operate near the Moon, on Mars, on key asteroids within the asteroids belt and elsewhere. We see immense cargo craft moving from Elevator to Elevator bringing supplies and equipment; and returning with raw materials for processing in one of the several GEO regions and later to Earth. This is the third dimension of trade, commerce, transportation, and humankind.

The total cost for NASA to launch PACE is approximately $80.4 million, which includes the launch service and other mission related costs. The PACE mission currently is targeted to launch in December 2022 on a Falcon 9 Full Thrust rocket from Cape Canaveral Air Force Station in Florida.

The PACE mission represents the nation’s next great investment in understanding and protecting our home planet. The mission will provide global ocean color, cloud, and aerosol data that will provide unprecedented insights into oceanographic and atmospheric responses to Earth’s changing climate. PACE will help scientists investigate the diversity of organisms fueling marine food webs and the U.S. economy, and deliver advanced data products to reduce uncertainties in global climate models and improve our interdisciplinary understanding of the Earth system.

**** SpaceX releases Rideshare Payload Users Guide (pdf). The Smallsat Rideshare Program provides payload space for small satellites on Falcon 9 launches. The a primary payload, typically a batch of the company’s Starlink satellites.

The prices are exceptionally low for smallsats, e.g. $1M for a 200kg satellite to sun synchronous polar orbit. The Rideshare website provides an interactive guide to estimating the cost for a smallsat mission. Reservations can also be made online.

The goal is to provide routine access to space.The launch opportunities will take place at regular intervals:

SSO missions approximately every 4 months.

So if a payload is delayed, it can ride on a subsequent launch.

If your payload is delayed, apply 100% of monies paid toward cost of rebooking on a future mission, subject to a 10% rebooking fee.

**** Total number of Falcon 9 launches will surpass 100 by end of this year if there are no major failures: SpaceX’s workhorse Falcon 9 rocket expected to reach major launch milestone in 2020 – Teslarati

Hours after SpaceX launched its 240th new Starlink satellite into orbit, Elon Musk took to Twitter to cryptically reveal that the company’s workhorse Falcon 9 rocket could “reach triple digits this year” if everything goes according to plan.

Designed and built by SpaceX in the late 2000s, the Falcon 9 rocket launched for the first time in June 2010. Developed for the unfathomably low price of $300 million from clean-sheet design to first orbital launch, the original single-core Falcon 9 rocket – known as V1.0 – was about 48m (160 ft) tall, weighed 333 metric tons (735,000 lb) fully fueled, and was capable of launching almost 10.5 metric tons (23,000 lb) into low Earth orbit (LEO). Famously, when provided with Falcon 9’s basic specifications and characteristics, an independent NASA study estimated that the rocket’s development would have cost the agency anywhere from $1.7 billion to $4 billion to design and build.

**** Falcon 9 booster for the latest Starlink mission returns from the sea. The booster landed harder than usual but the legs absorbed the impact just fine.

Here is a view of the booster’s return from USLaunchReport:

B1051 is still in excellent shape. The landing legs did their job. Appears to be approx. 5ft lower than normal. Incredible when you think of the force the landing legs must absorb.

****** First SN-1 Starship test flight could happen in a couple of months: SpaceX requests permission to fly new Starship rocket on 12-mile-high test flight – The Verge

SpaceX is already planning the next big test flight of its future Starship rocket out of southern Texas. As early as mid-March, the company is hoping to fly a test version of the vehicle to a super high altitude and then land it upright on solid ground, proving the rocket can be reused and potentially touch down on other worlds.

The upcoming test is detailed in new paperwork SpaceX filed with the Federal Communications Commission, which provides licensing to aerospace companies that are hoping to fly their vehicles to space. Specifically, the FCC allocates which radio frequencies companies can use to communicate with their vehicles during flight.

SpaceX notes in its filing that it wants special authority to communicate with its Starship rocket while the vehicle flies to an altitude of 12.4 miles or 20 kilometers — nearly halfway to the edge of space. Starship would take off from SpaceX’s test facility at Boca Chica, Texas, and the company would attempt to land the vehicle near the launch site using the rocket’s Raptor engines. SpaceX also plans to send data of the vehicle’s trajectory to both the Air Force and NASA.

****** To achieve a SN-1 flight so soon, activities are ramping up at Boca Chica Beach. New tanks are being assembled, the stainless steel bands for the main fuselage of the SN-1 Starship are being produced and stacked, several new structures have gone up to protect manufacturing from the elements, the last of the private residents near the site are being bought out to make it less hazardous to carry out tests and launch activities, and new workers are being hired.

Space transport roundup – June.29.2020

A sampling of recent articles, videos, and images dealing with space transport (find previous roundups here):

** SpaceX successfully launched a fourth batch of 60 Starlink satellites today from Cape Canaveral. The first stage booster landed safely and one of the two nosecone fairings was caught in a net on a ship as well. The other fairing had a soft landing near a second ship and will probably be recovered for possible reuse.

** Spinlaunch and its centrifugal catapult launch system are described in the most detailed public article released so far for the secretive company: Inside SpinLaunch, the Space Industry’s Best Kept Secret | WIRED

In SpinLaunch’s design, once a rocket is spinning at launch speeds, an exit port in the centrifuge will open for a fraction of a second, sending the rocket shooting out. According to patents filed by the company, a counterbalance spinning opposite the rocket gets released at the same time, preventing the tether from becoming unbalanced and vibrating into oblivion. The rocket coasts for about a minute and ignites its engines at roughly 200,000 feet. At that altitude, there’s hardly any atmosphere pushing against the rocket, so a minute-long engine burn is about all it takes to boost the vehicle to orbital speeds of around 17,500 miles an hour. Another burn, this one lasting just ten seconds, helps the rocket slide into orbit around Earth.

Or so [Spinlaunch founder and chief Jonathan] Yaney assures me. When I visited the company, the prototype centrifuge was still in pieces and Yaney wouldn’t show me any videos of it in action. Instead, he insisted the math of SpinLaunch engineers was solid. Major investors—including Airbus Ventures, Kleiner Perkins, and GV (part of Alphabet)—have given their blessing too, pumping $80 million into the company. And last year, the US Department of Defense awarded SpinLaunch a contract to help develop its centrifuge. Still, the scant public evidence that any of it works leaves much to the imagination.

** Blue Origin to use Air Force facility to test BE-7 lunar lander engine. Blue will fund major improvements to the site located on Edwards Air Force Base in California.

The Air Force Research Laboratory and Blue Origin are developing a new test facility for the Blue Origin BE-7 lunar lander engine at the AFRL rocket lab here.

Capital improvements, funded by Blue Origin, will allow BE-7 testing in a simulated space-like environment. Planned work includes adding liquid hydrogen and liquid oxygen propellant capabilities, along with other facility upgrades.

AFRL and Blue Origin signed a 15-year Cooperative Research and Development Agreement Dec. 11, 2019 to develop a test facility for the Blue Origin BE-7 Lunar Lander Engine here. The CRADA was signed by Dr. Shawn Phillips, chief of the Rocket Propulsion Division, and Bob Smith, CEO of Blue Origin.

The BE-7 engine is a new, high performance 10,000 pound-thrust dual-expander cycle engine for in-space applications, including Blue Origin’s Blue Moon lunar lander. The new AFRL test capabilities will support various development, qualification, and production acceptance tests of the BE-7 engine under future Commercial Test Agreements, also to be funded by Blue Origin.

“The Altitude facility at Edwards Air Force Base, California, does tactical scale research on next generation rocket motor and engine components, propellant formulations, and subsystems; and high vacuum research on satellite components, subsystems, and systems. Research testing includes solid rocket motor testing at simulated altitudes up to 120,000 feet. The complex has been used for space simulation to validate thrust vector control systems, baseline a standard for solid rocket motor propellants, research extendable nozzle cones, and systems, and research space qualified ignition systems.” Credits: AFRL

Startup Exodus Space Corp. plans to build a space plane to ferry cargo around Earth. Eventually, that cargo could include people, if the spacecraft is deemed safe enough.

The spaceship — called AstroClipper — will take off from a runaway, make a flight into space and then land again, plane-style. A heft booster at the space plane’s back end will help it get into orbit by giving AstroClipper the speed it requires to break out of Earth’s atmosphere.

Exodus is new and still raising money, but its team includes deep experience across the space industry. Principals at the company have worked at SpaceX, Lockheed Martin and NASA, among others.

**** Crew Dragon abort test flight accomplished all the primary mission goals according to results released so far: SpaceX releases preliminary results from Crew Dragon abort test – Spaceflight Now

Data from the Jan. 19 in-flight launch escape demonstration of SpaceX’s Crew Dragon spacecraft indicate the performance of the capsule’s SuperDraco abort engines was “flawless” as the thrusters boosted the ship away from the top of a Falcon 9 rocket with a peak acceleration of about 3.3Gs, officials said Thursday.

The Jan. 19 test demonstrated the Crew Dragon’s ability to safely carry astronauts away from a launch emergency, such as a rocket failure, and return the crew to a parachute-assisted splashdown in the Atlantic Ocean.

**** Starship

****** SpaceX conducted multiple pressure tests on propellant tanks in the past several days at the Boca Chica Beach facility. These included tests on a prototype nosecone tank and on a second large main propulsion tank. (The nosecone header tank is used to keep the center of mass of the Starship positioned correctly as propellants are fed into the engines.) The tanks were each tested to the point of destruction so as to determine the margin of safety above their planned operating pressures. The latest large tank test used liquid nitrogen, whose cryogenic temperature strengthens the stainless steel structure. The tank did not burst until the pressure reached 8.5 bar, which Elon Musk said was the target level. The highest operating pressure will be 6 bar.
