Space transport roundup – Dec.31.2019

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

** China’s Long March 5 heavy lift rocket placed a satellite into geostationary transfer orbit last Friday in a successful return to flight following a failure on the second launch of the system in 2017.

China can now proceed with a series of important launches including a Mars rover in July, a new crew spacecraft in September, and the Chang’e 5 lunar sample return mission in late 2020. The LM-5 is also needed for the  launch of modules for a new space station that begins assembly in 2021.

** Interstellar Technologies to carry out the fifth launch of an suborbital MOMO rocket in Japan. The liftoff planned forlast  Saturday was scrubbed:

MOMO-F5 sounding rocket countdown has been halted due to range safety and technical issue. Launch is scrubbed for this window.

Next launch attempt is currently set for January 1st. Get updates on the next launch attempt at Interstellar Technologies, Inc. (@natsuroke) | Twitter

The event will be live-streamed.

** Boeing Starliner Calypso returned unscathed by launch and reentry:

Boeing emphasized the good condition of the spacecraft, which showed “little scorching” from reentry and used only a fraction of its onboard propellant reserved for reentry, which the company said confirmed aerodynamic models of the spacecraft. The interior of the Starliner cabin appeared the same after landing as it did before its Dec. 20 launch from Cape Canaveral, the company noted, evidence that “the Starliner’s fully operational life support system functioned as intended and the layout of the interior is well-suited to support crew members in the future.”

The statement, though, provided no updates on the timer problem that turned what was originally an eight-day mission into a two-day one without a planned docking at the International Space Station. The spacecraft’s mission elapsed timer, which is set by communicating with its Atlas 5 rocket prior to liftoff, was off by 11 hours. That caused the spacecraft to think it was on the wrong phase of its mission after separation from the rocket’s upper stage, triggering thruster firings that used excessive amounts of fuel until ground controllers could take over and turn off the thrusters.

** Virgin Orbit nears first flight of the LauncherOne rocket: In One Year and Out the Other | Virgin Orbit

Now, we’re getting ready to shift all of our operations to the customized 747 that serves as our fully mobile launch site. Parked at “the hammerhead,” a part of the taxiway adjoining the primary runway at the Mojave Air and Spaceport, we’ll do the final mate of the rocket to Cosmic Girl and run through our rehearsals again. 

In January, we plan to have Chief Test Pilot Kelly Latimer and the rest of our flight crew guide us through one more taxi test with the mated rocket and an additional captive carry test with our orbital flight hardware. Then, we’ll be ready to light this candle and conduct our launch demonstration. 

For years, everything’s been building: our team, our market, our technical expertise, and our enthusiasm. As 2019 draws to a close, we’re stronger and smarter than we’ve ever been before, and feeling ready to rock. To stay in the loop, follow us on Twitter, Facebook, Instagram or LinkedIn.

** Firefly Aerospace also nearing debut of the Alpha smallsat launcher:

** The Chinese SIASAIL-I sail passes deployment tests following launch last September. The sail, developed by the Shenyang Institute of Automation (SIA), was packed within a CubeSat and successfully deployed in orbit. Although structurally the same as a solar sail, this sail test  is apparently aimed not at demonstrating net solar propulsion but at acceleration of spacecraft de-orbiting by increasing the drag through the minute amount of atmosphere  in low earth orbit.

From China Daily:

[Liu Jinguo, deputy director of the SIA Space Automation Technology Research Office, ]l  said that they managed to fold the flexible membrane and put it into the deployment machine, which is smaller than a billiard ball.

After the satellite platform is put into orbit, scientists carry out technical verification through two-stage deployment. At the first stage, the solar sail body is pushed out of the satellite platform and turned 90 degrees. The second stage is to erect masts and gradually spread the sail. The unfolded solar sail is about 0.6 square meters, which is equivalent to the size of eight Macbook airs laptop computers.

** LightSail 2: Fulfilling a Dream – Planetary Society – This solar sail did demonstrate net solar propulsion.

Carl Sagan dreamed of solar sailing before founding The Planetary Society in 1980. Now our members have helped us fulfill that dream.

** Bob Zimmerman reviews the rocket industry in the past year: The state of the global rocket industry in 2019 | Behind The Black

First and foremost 2019 showed a decline in total launches from 2018, with global launches dropping from 111 to 97. The 2019 totals were also about 30% below the number of launches predicted by the various countries and launch companies that are now active.

Does this drop in launches mean that the rocket industry is in decline? Not at all. The 97 launches last year were also the most launches in a single year since 1990, when the Soviet Union existed and routinely puffed up the totals each year with many unnecessary launches prompted by their bloated communist bureaucracy. (See last year’s graph for the yearly numbers going back to 1980.)

More important, the numbers this year are based on a much more robust launch industry, made up of many more sound competing constituents, both public and private.

And he concludes:

Thus, it appears that 2020 could herald the beginning of a very aggressive worldwide space industry, achieving more launches each year than ever accomplished in any year since Sputnik launched in 1957.

** SpaceX:

**** Falcon 9 launch of Starlink 2 with the second set of 60 satellites is set for this Friday, Jan. 3rd at 10:24 pm EST (0324 GMT on 4th from Cape Canaveral. It appears that the static firing test on the pad may happen on the day before rather than the usual several days prior. This is consistent with their efforts to speed up the launch pace. The company hopes to do Starlink launches about twice a month in 2020.

**** SpaceX is trying the make the Starlink satellites less bright so as to ameliorate their impact on astronomy: SpaceX set to launch less reflective Starlink satellite – Orlando Sentinel.

A launch planned for Friday from the Space Coast will test a possible solution. SpaceX will experiment with a non-reflective coating on the bottom of one satellite in its next batch of 60, scheduled to lift off from launch complex 40 at Cape Canaveral Air Force Station at 11:20 p.m.

The Astronomical Society has had numerous conversations with SpaceX since the first Starlink launch, on May 23, to discuss how to make the satellites less intrusive. Even now, at their operating altitude of about 550 kilometers, they are still right on the edge of visibility to the unaided eye.

But for research-grade telescopes? They’re “ferociously bright,” Hall said. That means they’re getting in the way of data collection, with the streaks of light ruining the scientific quality of images.

**** CRS-19 Cargo Dragon set to depart from the ISS next Sunday, Jan. 5th. NASA.gov/live will broadcast the departure starting at 9:15 p.m. EST.

**** Elon linked on Twitter to a SpaceX-made Falcon 9 Crew Dragon simulation from 2011 that I posted on Youtube:

Unfortunately, I believe the licensees of the Muse soundtrack will benefit from the big bump in views rather than I.

**** Elon pointed to a new animation of a Crew Dragon mission to the ISS released this week:

**** Crew Dragon with astronauts on board could launch as soon as February but NASA reviews will take months (and that’s assuming the in-flight abort test goes well):

**** Starship

****** Elon posted a lot of info on development of the Starship on Tweeter in the past few days. Here’s a sampling:

Orbital vehicle in Texas:

The next vehicle, which will be referred to as SN1 rather than Mk.3, could be flying by March:

Forming and attaching stainless steel structures:

Pressurizing the tanks to push propellants into the turbo-pumps:

Autogenous refers to using a gaseous form of a propellant itself for pressurizing the tank rather than using a separate inert gas like helium. The high pressure composite pressure vessels (COPVs) to hold helium were involved in both Falcon 9 explosions. Helium is also quite expensive now.

****** New structures in construction: SpaceX borrows Tesla’s tent factory strategy for new Starship production HQ – Teslarati

Confirmed yesterday morning by CEO Elon Musk, SpaceX has copied Tesla’s approach to factory expansion and is building a giant tent to upgrade its South Texas Starship production facilities.

A big step towards more traditional aerospace-style manufacturing facilities, SpaceX has contracted the same company used by Tesla to create a fourth general assembly line (GA4) in a giant tent outside its Fremont, CA factory in 2018. Instead of Model 3s, however, Sprung Instant Structures (Sprung for short) is rapidly raising a large tent that will eventually allow SpaceX to fabricate and weld more Starship parts and sections in an enclosed environment, an improvement from the current practice of building prototypes out in the harsh environment of coastal Texas.

In typical fashion, Musk believes that the new enclosed production facilities – just a collection of shipping crates as of December 18th – could be ready to begin manufacturing Starship parts as early as next month, and the progress Sprung has made makes it unusually hard to fault his optimism.

Videos: “Space to Ground” ISS report – Dec.27.2019

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

** Down to Earth Swimming in the Universe – “I’d give a lot to see that view again” – Mike Fossum. I don’t understand why people doubt the economic value of space tourism. Many people will pay a lot to go to space to see the sights Fossum and other astronauts have been lucky see.

In anticipation of the space station 20th anniversary, NASA astronaut Mike Fossum shares how he experienced the universe differently during his time in low-Earth orbit in this episode of “Down to Earth – Swimming in the Universe.” This shift is known as “the Overview Effect,” a term coined by space philosopher Frank White.

** Christina Koch Record Breaking Spaceflight Interviews – December 27, 2019

Aboard the International Space Station, Expedition 61 Flight Engineer Christina Koch of NASA discussed her record-setting mission and life on the orbital outpost during a series of media interviews Dec. 27. Koch, who launched to the station back in March, will pass former NASA astronaut Peggy Whitson’s mark of 288 days in space for the longest single spaceflight by a woman on Dec. 28. Koch is scheduled to return to Earth Feb. 6 on a Russian Soyuz spacecraft with a total of 328 days in space, second only to former NASA astronaut Scott Kelly’s record of 340 days in space as the longest single flight by an American astronaut.

** #AskNASA┃ How Will Astronauts Live at the Moon?

NASA is working with its partners to design and develop a small spaceship that will orbit the Moon called the Gateway. This spaceship will be a temporary home and office for astronauts, just about a five-day, 250,000-mile commute from Earth. NASA’s Gateway Program Logistics Element Manager Mark Weiss answers questions about the Gateway’s development’s for the Artemis Missions. The first logistics service to the orbital outpost is expected to deliver science, cargo and other supplies in support of the agency’s new Artemis lunar exploration program, which includes sending the first woman and the next man to the surface of the Moon by 2024.
