** Major wing components for Sierra Nevada’s Dream Chaser delivered:

Sierra Nevada Corporation (SNC), the global aerospace and national security leader owned by Eren and Fatih Ozmen, uncrated both wings for its Dream Chaser spaceplane this month at the company’s Louisville, Colorado production facility. The wings’ arrival kicks off the much-anticipated integration phase of a beautiful and critical differentiator for Dream Chaser, the world’s only spaceplane owned by a private company and under contract with NASA.

“The wings are here and now we truly have butterflies in anticipation of this integration phase for Dream Chaser,” said SNC President Eren Ozmen. “Our spaceplane looks and functions unlike anything else in space – more technologically advanced but with all the heritage of the space shuttle program in its design. Dream Chaser’s first flight will be a soaring moment for all of us.”

The arrival kicks off the integration of the complex Wing Deployment System (WDS) as part of the continued assembly and integration of the vehicle. With their innovative folding design, the wings are stowed in the fairing ahead of launch. After the launch vehicle separates, the WDS deploys the wings and locks them into place. Dream Chaser’s steeply angled wings function as stabilizers for the lift generated by the body of the vehicle.

“The wings for Dream Chaser presented an interesting design challenge,” said Dream Chaser program director John Curry. “Not only must they survive in low-Earth orbit like a satellite, but they need to be operational in Earth’s atmosphere, like an aircraft.” Just like the structural body for Dream Chaser, the wings were manufactured by Lockheed Martin in Texas, a subcontractor to SNC, and are single bonded composite structures. This state-of-the-art technology saves weight without compromising strength and stiffness.

Dream Chaser is under contract with NASA for at least six cargo resupply and return service missions to the International Space Station under the Commercial Resupply Services 2 (CRS-2) contract. The Dream Chaser and attached Shooting Star transport vehicle can carry up to 12,000 pounds of supplies and other cargo, and returns delicate science to Earth with a gentle runway landing.

And another update here: This Rocket Company Is Staying Calm, Carrying On With Fresh Contract And A New Launch Date – Forbes

As of this week, there are roughly 300 employees in Firefly, and more hires are coming quickly on the production side, to prepare for the first flight. “The secret to success in this business is staying focused,” Markusic said of Firefly’s efforts to send its first rocket aloft, which has experienced a few delays along the way. (But as any space company will point out, hardware development is difficult and costly, especially when novel technology is involved.)

There have been challenges in developing the Alpha rocket, whose novel features include propellant tanks and structures are built with carbon fiber composites, to reduce cracks and leaks while storing supercooled liquid oxygen. Estimates for the first launch date have been pushed back a few times, and a fire broke out during testing of a rocket stage in January.

But the payoff should be worth it in the long run, chief revenue officer Brad Schneider said during the same interview. Firefly projects that once the rocket starts flying, the company should see a “ramp” in revenues as money flows in from paying customers. Providing the test launch in 2020 goes to plan, revenues should start flowing faster in 2021 and accelerate in 2022, getting to a break even point relatively quickly after the upfront $165 million cost in development, preparing for the first flight and building the first two vehicles.

** Scott Manley reports on the latest Iranian launch of a satellite, achieving orbit successfully for the first time:

Earlier this week Iran made their first successful satellite launch in a long time using a new rocket design named ‘Qased’.

** Chinese Long March 3B fails to put Indonesian communications satellite into orbit: Long March 3B fails during Indonesian satellite launch –

A new communications satellite attempted to make its way into for Indonesia via a China Great Wall Industry Corporation launch on Thursday using a Long March-3B/G2 (Chang Zheng-3B/G2) rocket. The launch took place at 11:45 UTC from the LC2 pad at the Xichang Satellite Launch Center, but reportedly failed during third stage flight. The satellite is understood to have already reentered and has thus been destroyed.

The satellite, based on the Chinese DFH-4 platform, was to be used by PT Pasifik Satelit Nusantara (PSN) in cooperation with telecommunication service provider PT Indosat Ooredoo and PT Pintar Nusantara Sejahtera (PNS), to provide broadband internet access and high-quality broadcasting services.

Reports from China noting an issue with the Long March’s third stage has resulted in the mission being classed as a failure.

** Rocket Lab demonstrates mid-air booster capture and recovery operation with a helicopter: Rocket Lab Successfully Completes Electron Mid-Air Recovery Test   | Rocket Lab

Rocket Lab, a space systems company and the global leader in dedicated small satellite launch, has successfully completed a mid-air recovery test – a maneuver that involves snagging an Electron test stage from the sky with a helicopter. The successful test is a major step forward in Rocket Lab’s plans to reuse the first stage of its Electron launch vehicle for multiple missions. The test took place in early March, before ‘Safer at Home’ orders were issued and before New Zealand entered Alert Level 4 in response to the COVID-19 situation.

The test was conducted by dropping an Electron first stage test article from a helicopter over open ocean in New Zealand. A parachute was then deployed from the stage, before a second helicopter closed in on the descending stage and captured it mid-air at around 5,000 ft, using a specially designed grappling hook to snag the parachute’s drogue line. After capturing the stage on the first attempt, the helicopter safely carried the suspended stage back to land.

The successful test is the latest in a series of milestones for Rocket Lab as the company works towards a reusable first stage. On the company’s two most recent missions, launched in December 2019 and January 2020, Rocket Lab successfully completed guided the re-entries of Electron’s first stage. Both stages on those missions carried new hardware and systems to enable recovery testing, including guidance and navigation hardware, S-band telemetry and onboard flight computer systems, to gather data during the stage’s atmospheric re-entry. One stage was also equipped with a reaction control system that oriented the first stage 180-degrees for its descent, keeping it dynamically stable for the re-entry. The stage slowed from more than 7,000 km per hour to less than 900 km by the time it reached sea-level, maintaining the correct angle of attack for the full descent.

The next phase of recovery testing will see Rocket Lab attempt to recover a full Electron first stage after launch from the ocean downrange of Launch Complex 1 and have it shipped back to Rocket Lab’s Production Complex for refurbishment. The stage will not be captured mid-air by helicopter for this test, but will be equipped with a parachute to slow its descent before a soft landing in the ocean where it will be collected by a ship. This mission is currently planned for late-2020.

As the country and the world face the challenges of the COVID-19 pandemic, NASA is leveraging virtual presence and communications tools to safely make progress on these important lunar exploration activities, and to award this lunar surface delivery as it was scheduled prior to the pandemic.

“Under our Artemis program, we are going to the Moon with all of America,” said NASA Administrator Jim Bridenstine. “Commercial industry is critical to making our vision for lunar exploration a reality. The science and technology we are sending to the lunar surface ahead of our crewed missions will help us understand the lunar environment better than we ever have before. These CLPS deliveries are on the cutting edge of our work to do great science and support human exploration of the Moon. I’m happy to welcome another of our innovative companies to the group that is ready to start taking our payloads to the Moon as soon as possible.”

The $75.9 million award includes end-to-end services for delivery of the instruments, including payload integration, launch from Earth, landing on the Moon’s surface, and operation for at least 12 days. Masten Space Systems will land these payloads on the Moon with its XL-1 lander.

A small rover is included in the payloads. See the NASA announcement for a full list of the payloads.

SpaceX is preparing to launch another batch of satellites for the Starlink Internet network from Florida’s Space Coast as soon as April 16, a sign that launch operations at Cape Canaveral could continue at a reduced pace amid the global coronavirus pandemic.

The launch next week is also set to occur weeks after a major competitor to SpaceX’s Starlink network filed for bankruptcy.

The mission is set for launch at around 5:31 p.m. EDT (2131 GMT) next Thursday, April 16, from pad 39A at NASA’s Kennedy Space Center in Florida.

No word from SpaceX yet regarding the cause of an early shutdown of a Merlin engine on the first stage booster during the last Starlink launch. That booster was on its fifth launch, the first Falcon 1st stage to reach that many reuses. The satellites successfully reached orbit but the booster failed to land on the ocean platform.

The total number of Starlink satellites to reach orbit so far is 362 Starlink satellites. About five have de-orbited and the first 60 on the “Starlink 0” appear to be treated as test vehicles and may not participate in an operational Internet service.

** Starship prototype SN3 collapses near end of pressure testing of propellant tanks. Rather than an explosive rupture as in previous tank failures, the center tank just crumpled and collapsed. Apparently, the weight of the liquid nitrogen in the upper tank overcame the structural integrity of the middle tank. This could have happened if the middle tank was de-pressurized prematurely. This is the sort of mistake Elon Musk was referring to in a Tweeter posting after the failure in which he said, “this may have been a test configuration mistake.”

** Sierra Nevada reports on progress with the VORTEX propulsion system: SNC Leverages VORTEX® Engine Technology for DARPA’s OpFires Program

Sierra Nevada Corporation (SNC), the global aerospace and national security leader owned by Eren and Fatih Ozmen, reached a major milestone in the advancement of hypersonic propulsion with its patented VORTEX engine, advancing to the next phase of the Defense Advanced Research Projects Agency’s (DARPA) Operational Fires (OpFires) program.

Through OpFires, SNC is extending its hybrid VORTEX engine capabilities to advanced, deep throttling, restartable propulsion systems. The system utilizes benign solid fuel with a liquid oxidizer, both of which are storable on Earth and in space. Recent testing shows positive results in being able to package significant energy into a small volume that will have the ability for deep throttling and smooth restart capabilities on command. “The VORTEX flows integrated into the hybrid significantly improves performance of the hybrid engine” said Dr. Marty Chiaverini, director of Propulsion Systems at SNC.

“This program opens up a new market for SNC for preplanned or on-demand propulsion control capabilities that are applicable to both military and beyond Earth orbit propulsion capabilities,” said Tom Crabb, vice president of SNC’s Propulsion & Environmental Systems business unit. “Deep throttling and restart capabilities expand the tools for smart and unpredictable trajectories for various vehicles and systems.”

The first two phases of DARPA’s OpFires program focus on the propulsion technologies required to deliver diverse payloads to a variety of ranges. Since Phase 1 contract award, SNC has made critical discoveries in advanced rocket motor technology for the OpFires upper stage, completing more than 30 motor trials from subscale through full size. SNC hopes to demonstrate these engines in flight and offer the engines to new, promising vehicle systems.

In addition to the deep throttling, restartable, storable system for DARPA, SNC is expanding its propulsion capabilities and products with near-term flight for its Dream Chaser® spaceplane Reaction Control System, maturation of upper stage engines and development of other liquid storable engines for spacecraft, lunar, and other exploration and protection applications. SNC is also co-investing with the U.S. Air Force (USAF) for development of the engine for USAF needs. For more information, visit

Following in the footsteps of the late Mk1 vehicle, SpaceX’s latest Starship prototype has been outfitted with several Tesla battery packs and motors over the last few weeks.

CEO Elon Musk has confirmed in the past that SpaceX intends to try to use Tesla batteries to power Starship rockets and Tesla motors to drive the ships’ large aerodynamic control surfaces. By all appearances, a Tesla Model S motor’s appearance on the exterior of a Starship prototype recently moved to the launch pad is a first for SpaceX. However, in 2019, SpaceX at one point planned to use and even installed battery packs on Starship Mk1 components before the ship was prematurely destroyed during testing. The nosecone those battery packs were installed in still sits in the middle of SpaceX’s growing Boca Chica rocket factory.

For Starship SN3, the purpose of its ~200 kWh of battery power is rather self-explanatory. The purpose of the Tesla Model S motor recently installed on its side is much less clear.

The award is a significant step forward for NASA’s Artemis program that will land the first woman and next man on the Moon by 2024 and build a sustainable human lunar presence.

At the Moon, NASA and its partners will gain the experience necessary to mount a historic human mission to Mars.

SpaceX will deliver critical pressurized and unpressurized cargo, science experiments and supplies to the Gateway, such as sample collection materials and other items the crew may need on the Gateway and during their expeditions on the lunar surface.

“This contract award is another critical piece of our plan to return to the Moon sustainably,” said NASA Administrator Jim Bridenstine. “The Gateway is the cornerstone of the long-term Artemis architecture and this deep space commercial cargo capability integrates yet another American industry partner into our plans for human exploration at the Moon in preparation for a future mission to Mars.”

NASA is planning multiple supply missions in which the cargo spacecraft will stay at the Gateway for six to 12 months at a time. These firm-fixed price, indefinite delivery/indefinite quantity contracts for logistics services guarantee two missions per logistics services provider with a maximum total value of $7 billion across all contracts as additional missions are needed.

Eric Berger talks with two NASA Artemis program managers about the benefits of the Dragon XL services for the Gateway: NASA officials outline plans for building a Lunar Gateway in the mid-2020s | Ars Technica

Ars: It seems to me that Dragon has some capability to really add some volume to Gateway. Can you talk a little bit about its capabilities?

[Mark Wiese, Deep Space Logistics manager]: We went back and looked at some of the lessons learned from Commercial Resupply Services (CRS), and the early missions of CRS really didn’t have the capability within the modules to support research. If you look at SpaceX’s first two or three missions and look at where we are on SpaceX’s 20th mission, the capabilities that Dragon offers for research are significantly improved, and so we took that into account.

[Dan Hartman, Gateway program manager]: We’re going to put payloads on the inside, and we’ve got quite a bit of power allocated from the Dragon XL for that. We’ve got upmass allocated for payloads inside and then we can also fly payloads on the outside with power and tied into their communication systems so we can get some research back down, real time on the way to the Moon, and while attached at the Moon. And then quite honestly, we don’t need the logistics mission up there for six months or a year just to support a lunar mission. But we wanted to take advantage of the extra volume, the extra research accommodations, where we could keep it attached, and we could run science. Dragon also has got the automated rendezvous and docking system that they will be using on their CRS-2 vehicles, very similar to their Crew Dragon. And so, the docking system, you can come and go. We were planning to do that remotely without crew in there. And so, we think we’re set up for a really good platform to conduct research for the long haul.

** Stratolaunch unveils hypersonic vehicle designs. The vehicles will be air launched from the company’s gigantic carrier aircraft, sometimes referred to as Roc.  The initial goal is development of Talon-A

Talon-A is a fully reusable, autonomous, liquid rocket-powered Mach 6-class hypersonic vehicle with a length of 28 feet (8.5 m), wingspan of 11.3 feet (3.4 m), and a launch weight of approximately 6,000 pounds (2,722 Kg). The Talon-A will conduct over 1-minute of hypersonic flight testing, and glide back for an autonomous, horizontal landing on a conventional runway. The vehicle will also be capable of autonomous take-off, under its own power, via a conventional runway.

Following the death of founder and owner Paul Allen in 2018, the company announced that it was giving up on plans to become an orbital launch provider using rockets launched from beneath the Roc. There was talk the company would even close down after the first successful flight of Roc in April of 2019. Instead Stratolaunch was acquired by Cerberus Capital Management in the summer of 2019 and the company became focused on using Roc for hypersonic research.

Hypersonic propulsion and vehicle design have become top priorities for the US Air Force in response to heightened Chinese and Russian activity in these areas. While the military is focused primarily on hypersonic missiles and projectiles, development of hypersonic transports are also of interest.

Talon Z would be the follow-on hypersonic vehicle to the Talon-A. No details of its design have been revealed yet.

Company management has indicated that several years from now they expect  to return to the orbital space transport challenge with the development of  Black Ice:

Black Ice is a fully reusable space plane that enables advanced on-orbit capabilities and cargo return. Initial designs optimized for cargo launch, with a follow-on variant capable of transporting crew.

** Astronaut selection for the first operational Crew Dragon mission has been announced: NASA Adds Shannon Walker to First Operational Crewed SpaceX Mission | NASA

NASA has assigned astronaut Shannon Walker to the first operational crewed flight of the SpaceX Crew Dragon spacecraft on a mission to the International Space Station.

Walker will join NASA astronauts Michael Hopkins and Victor Glover Jr., as well as Soichi Noguchi of the Japan Aerospace Exploration Agency (JAXA), for a six-month expedition aboard the unique space laboratory.

This mission will be the first in a series of regular, rotational flights to the station following NASA’s certification of the new crewed system following completion and validation of SpaceX’s test flight with astronauts, known as Demo-2. This test is expected to take place in mid-to-late May as part of NASA’s Commercial Crew Program.

Pending the successful Demo-2 test, Walker, Glover, Hopkins, and Noguchi will launch aboard Crew Dragon on SpaceX’s Falcon 9 rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida. That launch is targeted for later this year.

** The Demo-2 astronauts are busy with simulations of the mission, which could happen as early as mid-May: NASA, SpaceX Simulate Upcoming Crew Mission with Astronauts | NASA

Joint teams from NASA and SpaceX continue making progress on the first flight test with astronauts to the International Space Station by completing a series of mission simulations from launch to landing. The mission, known as Demo-2, is a close mirror of the company’s uncrewed flight test to station in March 2019, but this time with NASA astronauts Bob Behnken and Doug Hurley aboard the Crew Dragon spacecraft launching atop a Falcon 9 rocket as part of NASA’s Commercial Crew Program (CCP).

Over the last several months, key members of flight control teams working from NASA’s Johnson and Kennedy Space Centers and SpaceX headquarters in Hawthorne, California, simulated different phases of the upcoming mission while the Demo-2 astronaut crew practiced procedures from inside a realistic simulator of Crew Dragon.

“The simulations were a great opportunity to practice procedures and to coordinate decision-making for the mission management team, especially with respect to weather,” said Michael Hess, manager of Operations Integration for CCP. “Simulation supervisors do a great job at picking cases that really make the team think and discuss.”

Recent simulations saw teams execute timelines from hatch closure to undocking with the space station — as well as a free flight in preparation for re-entry and splashdown. In March, the control teams and crew ran through a simulated mission starting at prelaunch and continuing through ascent and eventual rendezvous with the station.

This recent sim makes the excitement all the more tangible, especially for the greater NASA team.

“On Thursday, March 19 and Friday, March 20, SpaceX teams in Firing Room 4 at NASA’s Kennedy Space Center in Florida and the company’s Mission Control in Hawthorne, California, along with NASA flight controllers in Mission Control Houston, executed a full simulation of launch and docking of the Crew Dragon spacecraft, with NASA astronauts Bob Behnken and Doug Hurley (front) participating in SpaceX’s flight simulator. ” Credits: SpaceX

Mission profile:

United Launch Alliance will use an Atlas V 551 rocket to launch the sixth and final spacecraft in the Lockheed Martin-built Advanced Extremely High Frequency (AEHF) series for the U.S. Space Force Space and Missile Systems Center. AEHF satellites provide global, survivable, protected communications capabilities for strategic command and tactical warfighters operating on ground, sea and air platforms. Atlas V rockets successfully launched the first five AEHF satellites between 2010 and 2019.

** Air Force will keep Cape Canaveral open: Military officials committed to keeping Cape Canaveral open for launches – Spaceflight Now

The military-run Eastern Range at Cape Canaveral remains ready to support upcoming launches — including an Atlas 5 flight Thursday — amid the coronavirus pandemic, officials said Tuesday.

The next launch scheduled from Cape Canaveral is set to take off Thursday, when a United Launch Alliance Atlas 5 rocket carries a U.S. Space Force communications satellite into orbit. Preparations for that mission are on schedule, officials said Tuesday.

“We’re going to continue to do what we do best, which is provide assured access to space, while also taking care of our airmen and their families,” said Brig. Gen. Doug Schiess, commander of the 45th Space Wing, which oversees Patrick Air Force Base and Cape Canaveral Air Force Station on Florida’s Space Coast.

Schiess told reporters Tuesday that the Pentagon has directed military commanders to protect their teams during the coronavirus pandemic, while continuing critical missions and supporting the government’s response to fight the spread of the virus.

** China launches Long March-2C rocket with remote sensing satellites

After losing the first Long March-7A one week ago, China launched a new group of triplet satellites for the Chuangxin-5 (CX-5) constellation. Launched under the name Yaogan Weixing-30 Group-6, the three satellites were orbited by a Long March-2C launch vehicle from the LC3 Launch Complex of the Xichang Satellite Launch Center. The launch took place at 03:43 UTC.

Like the previous missions on the series, this mission is once again classed as involving new remote sensing birds that will be used to “conduct electromagnetic probes and other experiments.”

As was the case in previous launches of the Yaogan Weixing series, analysts believe this class of satellites is used for military purposes, in particular forming a high-revisit smallsat constellation for signal intelligence missions or imaging activities.

** Astra rocket damaged on pad in preparation for orbital launch from Alaskan spaceport this week: Astra rocket damaged in pre-launch tests –

In an email late March 23, Chris Kemp, chief executive of Astra, said the rocket had been damaged in prelaunch testing earlier in the day. “We’ll be rescheduling launch,” he said, but had not selected a new launch date. He did not elaborate on the damage the rocket sustained.

Local radio station KMXT reported March 23 that there had been an “anomaly” at the launch site on Kodiak Island that prompted an emergency response. There were no injuries reported, but the area was cordoned off.

“The area is still hazardous and should be avoided. There will be personnel on site overnight to monitor,” Mark Lester, chief executive of Alaska Aerospace, which operates the spaceport, told KMXT after the emergency response concluded.

Here is an earlier report on the launch plan: Astra readies for possible launch attempt next week – Spaceflight Now

After missing out on an opportunity to win up to $12 million in prize money through DARPA’s Launch Challenge earlier this month, Astra is gearing up for another possible orbital launch attempt next week from Alaska, the company’s chief executive said Friday.

Chris Kemp, Astra’s co-founder and CEO, said in an email Friday to Spaceflight Now that Astra is not planning to launch Monday, but the company is “working towards a possible launch attempt later in the week” from the Pacific Spaceport Complex at Kodiak Island, Alaska.

The company’s first small satellite launcher was scheduled to take off during a two-week window in late February and early March in a bid to win the DARPA Launch Challenge. But schedule delays and an aborted countdown on the final day of the Launch Challenge window March 2 kept Astra from winning a $2 million prize from DARPA, which would have allowed the company to proceed to a second mission later this month with a $10 million prize attached.

** The Chinese startup launch company Galactic Energy plans to put a payload into orbit this summer: Galactic Energy Prepares Ceres-1 Rocket for First Launch – IEEE Spectrum

Galactic Energy, a low-key private Chinese rocket firm, celebrated its second birthday in February. That’s early days for a launch company, and yet the company is set to make its first attempt to reach orbit this June.

The rocket is named Ceres-1, after the largest body in the asteroid belt, and will launch from China’s Jiuquan Satellite Launch Center in the Gobi Desert. With three solid fuel stages and a liquid propellant fourth stage, it will be able to lift 350 kilograms of payload to an altitude of 200 kilometers in low Earth orbit.

The firm’s ability to move this quickly is due to a mix of factors—strong corporate leadership, an experienced team, and policy support from the Chinese state.

Concerns about the coronavirus pandemic have prompted officials to postpone the planned March 30 launch of Argentina’s SAOCOM 1B radar observation satellite from Cape Canaveral aboard a SpaceX Falcon 9 rocket, officials said Tuesday.

Travel restrictions imposed by coronavirus to slow the spread of the COVID-19 viral disease, and restrictions on non-essential work, have hindered space activity around the world. CONAE, Argentina’s space agency, said the launch of the country’s SAOCOM 1B Earth-imaging spacecraft will be postponed.

CONAE did not announce a new target launch date for the SAOCOM 1B mission.

As usual for these roundups, there is yet more news from Boca Chica on the acceleration of Starship prototype construction. Local stay-at-home proclamations for coronavirus protection look to be the only way that the Starshp development will be slowed. Welders wanted: SpaceX is hiring to ramp up production of stainless steel Starship |

SpaceX is looking to hire lots of folks to help ramp up production and testing of its ambitious Starship Mars-colonizing architecture over the coming months — and the company recently issued a public recruiting pitch.

“The design goal for Starship is three flights per day on average [per ship], which equates to roughly 1,000 flights per year at greater than 100 tons per flight. This means every 10 ships would yield 1 megaton per year to orbit,” Jessica Anderson, a lead manufacturing engineer at SpaceX, said last week during the launch webcast for the company’s latest batch of Starlink internet satellites.
