The Space Show this week – Dec.21.2020

The Space Show Asks For Your Support:

The Space Show wishes all of you a very Merry Christmas, Happy New Year, a healthy holiday season and 2021. Here at The Space Show we are winding down 2020, a year that has been challenging for us and each of you. Despite the year’s challenges we have managed to continue bringing you great guests, lots of listener participation with phone calls, emails and blog commentary. The Space Show has continued our strong advocacy for commercial space development, a lunar return and eventual humans to Mars mission plans. We have supported having a strong national security space policy plus we love our planetary science program which is the best in the world. Many of you have promoted your books, websites, blogs, ideas and work on The Space Show this year as well as in previous years. Students have been on The Space Show gaining valuable experience related to their future skills and career choices. The list of Space Show accomplishments is a lengthy one but I think you get the picture.

Production of The Space Show is expensive, so we ask for your support to continue working hard advocating for the space industry we all want, especially in these uncertain times for our industry and country. Fulfilling The Space Show mission is why we ask for your financial support. Thee Space Show, as a live broadcast internet radio talk show with multiple phone lines for the guests and listener discussions, is not just another podcast. Our unique format featuring live broadcasts, real time callers and listener emails helps The Space Show stand out bringing you in-depth information about all aspects of our industry. Each year we engage in our end of the year fundraising campaign to help continue our work into the coming year. We are now in our annual end of year campaign and we are asking you to please support The Space Show with a gift today. Don’t forget that as a nonprofit 501c3 with the One Giant Leap Foundation as our parent, your contribution entitles you to an IRS tax deduction along with a California tax deduction if you are a California tax payer (check with your tax advisor for details applicability). But tax deductions are not a reason to contribute to us. You contribute to us because of our programming, because we fight and advocate for what you want in space, because we educate with facts and solid information and because we offer everyone the opportunity for civil discussions on all space related topics. You contribute to us because you have a voice with our guests, with each other and in future programming. That is why you contribute and why we are asking you to contribute once again this year. We believe The Space Show delivers the value you deserve and that we have earned your respect which you show us by helping to financially support us.

Videos: “Space to Ground” + Other ISS reports – Dec.19.2020

Here is the latest episode in NASA’s Space to Ground weekly report on activities related to the International Space Station:

** ISS 20th Anniversary Panel: Trailblazing International Partnerships – NASA

The International Space Station is one of the most ambitious international collaborations ever attempted, and is a convergence of science, technology and human innovation that provides humanity a one-of-a-kind proving ground for Artemis as we go forward to the Moon and on to Mars. International collaboration in space exploration serves as an unparalleled and inspiring example of what humanity can do when it comes together to achieve a common goal for the common good. NASA’s partnerships with the Canadian Space Agency, European Space Agency, Japan Aerospace Exploration Agency, and Roscosmos aboard the space station have led to an unprecedented continuous human presence in space for nearly 20 years. In recognition of the 20th anniversary of continuous human presence aboard the International Space Station, listen as Space Foundation Board Member Jeanne Meserve sits down the International Space Station partner leaders as they discuss what it has taken to keep this global partnership successful. Joining the conversation is the International Space Station Partner Leadership consisting of Joel Montalbano of the National Aeronautics and Space Administration, Sergei Krikalev of Roscosmos, Luc Dubé of the Canadian Space Agency, Frank De Winne of the European Space Agency, and Junichi Sakai of the Japanese Aerospace Exploration Agency.

** Cosmic Kiss: Matthias Maurer’s first mission to the International Space Station – European Space Agency, ESA

ESA astronaut Matthias Maurer from Germany has been assigned his first mission to the International Space Station. He is expected to fly to the Space Station in the autumn of 2021. The mission is called Cosmic Kiss and Maurer will spend six months in orbit, carrying out vital science and operations on behalf of researchers and international partners worldwide.

** Greenhouse in Antarctica Helping Astronauts on Long-Duration Missions – NASA’s Kennedy Space Center

A few intrepid researchers will begin an arduous journey to Antarctica on Dec. 20 to conduct plant cultivation investigations in an extremely remote region of the world at the German Neumayer III Station, operated by the Alfred Wegener Institute (AWI). One researcher heading to this desolate wilderness on the Ekstrom Ice Shelf is Jess Bunchek. The plant scientist from NASA’s Kennedy Space Center will be a guest researcher at the German Neumayer III Station, operated by the Alfred Wegener Institute (AWI). Bunchek will spend about a year investigating plant cultivation in isolated, confined, and extreme (ICE) environments in the EDEN ISS greenhouse, managed by the German Aerospace Center (DLR) Institute of Space Systems. These efforts complement NASA research on growing plants in the ultimate closed loop environment – space. For more than 20 years, a multinational partnership has allowed astronauts to live and work in a unique microgravity laboratory aboard the International Space Station. Research conducted at the EDEN ISS greenhouse on this mission could benefit people on Earth and astronauts on future missions to the Moon and Mars.

Rockets, Space transport roundup

Space transport roundup – Dec.16.2020

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

** Dec.9: First high altitude flight test of a SpaceX Starship prototype successfully demonstrated two key requirements for returning from orbit: (1) controlled stable flight while in a horizontal orientation during unpowered descent and (2) the flip to vertical maneuver after restarting the engines. The vehicle was powered by three Raptors, which fired for nearly five minutes before reaching the 12 km altitude. (Two of the engines shut down sequentially during the later phase of the ascent.) This provided a big gain in the amount of data on in-flight performance of the LOX/Methane engines compared to the short hops with earlier prototypes.

Unfortunately, during the SN8 vehicle’s relatively short vertical descent to the bullseye of the landing pad, a drop in pressure from the propellant tank in the tip of the nosecone reduced the thrust of the Raptor engine and the vehicle landed too hard and exploded. This operational problem can be prevented in a straight-forward manner in future flights. After 60+ successful Falcon 9 booster recoveries, the company knows how to land a rocket vertically.  However, SpaceX has had no experience with flying a rocket in a horizontal attitude and controlling it with side fins. It also had never swung a vehicle from horizontal to vertical. So this was a very successful test. While it might have flown again if it landed safely, SN8 was never intended to provide more than suborbital test data.

This multi-exposure image nicely captures the liftoff and return of Starship SN8’s epic test flight:

** Dec.16: Astra reaches space for first time but falls just short of orbit: The launch from the Alaskan spaceport sent the upper stage of the two-staged Rocket 3.2 to 390 kilometers in altitude and “just a half a kilometer per second short” of orbital velocity according to Astra CEO Chris Kemp. According to Eric Berger,

The company had not quite gotten the mixture of kerosene to oxidizer correct—something that is difficult to test on the ground—and wound up with an excess of liquid oxygen. Had the upper stage burnt kerosene for a few more seconds, the upper stage would have reached orbit. As it was, the booster peaked at an apogee of 390km above the Earth’s surface.

Kemp claimed this flight nevertheless exceeded the team’s expectations for the rocket, which did not have a payload on board.

Kemp has said that it would take three launches before they achieved orbit. Last March, Rocket 3.0 was destroyed in a fire on the pad and, in September, Rocket 3.1 flew for 30 seconds before a guidance problem led to a shutdown of the engines and the loss of the vehicle. Rocket 3.3 is expected to fly early in 2021 and it will carry a payload for a customer.

The company’s goal is to offer very low cost access to orbit for small satellites. To achieve this they have sought a simple but robust rocket design that can be built at low cost. According to Astra,

Rapid test and iteration are the cornerstones of our development process. We’ve performed thousands of rocket engine tests at our headquarters in Alameda, a few hundred feet away from where those engines are designed and built. We can afford to experiment quickly and repeatedly because our rockets are far less expensive. The rockets are primarily constructed from lightweight aluminum, instead of costly composite and 3D printed materials.

Small crews for launch are also a part of the plan: Astra set up a rocket launch with five people and came within seconds of orbit | Ars Technica

Astra was founded to provide rapid, low-cost access to space for small satellites. The quick turnaround between its first and second flights suggests it may make good on this promise. It’s impressive, too, that the company needs just five people to set up its launch site. At Kodiak, Astra has a concrete pad and a tent. A week before launching the rocket, its launcher, propellant, and other equipment arrived in four shipping containers from California. A team of five set the launch system up, and employees back at Astra’s headquarters in Alameda, California, controlled the launch through cloud computing.

The company needs to prove in 2021 that it can build and operate rockets that not only get to orbit but do so reliably and frequently.

** Dec.15: Rocket Lab Electron rocket puts Synspective StriX-α synthetic aperture radar (SAR) satellite into a 500km circular orbit. This was the 17th Electron launch. There was no attempt to recover the first stage.

** Dec. 12: Virgin Galactic SpaceShipTwo test flight aborted after avionics failure prevents engine ignition: Virgin Galactic Update on Test Flight Program – Virgin Galactic

Virgin Galactic Holdings, Inc. (NYSE: SPCE), a vertically integrated aerospace and space travel company, announced an update following its recent test flight on December 12, 2020. During the test flight, the rocket motor did not fire due to the ignition sequence not completing. Following this event, the pilots conducted a safe landing and return to Spaceport America, New Mexico as planned.

Virgin Galactic is now conducting post-flight analysis and can so far report that the onboard computer which monitors the propulsion system lost connection, triggering a fail-safe scenario that intentionally halted ignition of the rocket motor. This system, like others on the spaceship, is designed such that it defaults to a safe state whenever power or communication with sensors is lost. The pilots in the spaceship, as well as the engineers and pilots in mission control, are well prepared for any off-nominal results, as they plan and rehearse many potential scenarios during pre-flight simulation practice sessions, including a scenario where the rocket motor does not ignite after release from the mothership.
