Capitalism in space: ULA’s Atlas-5 rocket today successfully launched Boeing’s manned Starliner capsule into orbit on its second attempt to complete an unmanned demo mission to ISS.

The capsule having been deployed by the rocket then followed with a final burn using the capsule’s own engines to get into its proper orbit for rendezvous with ISS tomorrow at 7:10 pm (Eastern). It was during this rendezvous period that Starliner had its problems in the first demo mission in December 2019 that caused the mission to be aborted prior to docking. Hopefully those software issues have been solved and all will go well through tomorrow.

It is interesting to compare the operation and equipment of Boeing/ULA vs SpaceX. While SpaceX has aimed for a sleek look, Boeing/ULA both retain the industrial feel of past rocketry. Neither is wrong, but the difference highlights the consequences of having competing operations. You get variety.

The leaders in the 2022 launch race:

21 SpaceX
15 China
7 Russia
3 Rocket Lab
3 ULA

American private enterprise now leads China 30 to 15 in the national rankings, and the entire world combined 30 to 25.

NASA bans American spacewalks on ISS because of chronic spacesuit issues

10:04 am

NASA's failed spacesuit
NASA’s failed Moon spacesuits

Because of repeated water leaks in the helmets of NASA’s complex spacesuits and the agency’s inability to fix the problem, agency managers have to decided to cease all American spacewalks on ISS until engineers can definitively solve the problem.

The problem first occurred during a 2013 spacewalk, causing a major investigation. Though engineers managed to gain some control over the problem, it was never truly solved. In the most recent spacewalk on March 23rd, astronauts found water inside one helmet after the walk was over. That suit will now be returned to Earth for inspection and engineering work.

This suspension of spacewalks likely delays four spacewalks planned this year to complete the upgrade to the station’s power system.

Meanwhile, NASA’s own program to build new spacesuits for its lunar missions has been an utter failure — costing more than a billion dollars over fourteen years and producing nothing — thus forcing the agency to turn to the private sector to get new suits.

Study: Russian astronauts on ISS have better techniques for protecting the brain

9:12 am

According to a study comparing the changes in the brain experienced during long term missions on ISS, it appears that the Russians have developed better protocols for preparing themselves for return to Earth that prevents the enlargement in one part of the brain seen in American astronauts.

From the link:

The study focused on 24 Americans, 13 Russians, and a small, unspecified number of astronauts from the ESA. The researchers collected MRI scans of the astronauts’ brains before and after they spent six months on the ISS (only 256 individuals have visited the space station).

After being in space, all the space travelers exhibited similar brain changes: cerebrospinal fluid buildup and reduced space between the brain and the surrounding membrane at the top of the head. The Americans, however, also had more enlargement in the regions of the brain that serve as a cleaning system during sleep, e.g. the perivascular space (PVS).

…The Russian astronauts did not exhibit enlarged PVS, suggesting there might be differences in protocol that are neuro-protective.

From the paper itself:

[Russian C]osmonauts undergo six lower body negative pressure (LBNP) sessions starting two weeks prior to landing, while NASA and ESA astronauts do not typically do it. LBNP induces caudal displacement of fluids from the upper body by placing the legs and pelvis in a semiairtight chamber with negative pressure.

An advanced resistive exercise device (ARED) is regularly used by space flyers to perform free weight exercises on the ISS, but the load and frequency of use are lower for [Russian] cosmonauts compared with NASA and ESA astronauts. Lifting heavy loads during resistive exercise is often accompanied by a brief Valsalva maneuver, inducing increased ICP and decreased cerebral blood flow and cerebrovascular transmural pressure, which can result in PVS fluid accumulation. Although the effects of LBNP and ARED on the brain during spaceflight are unknown, they could partly explain the different WM-PVS changes detected in astronauts and cosmonauts. We cannot exclude that other factors (e.g., diet) might play a role in this difference. Further studies are required to confirm these hypotheses.

Apparently two protocols are different that seem to help the Russians. First, the LBNP, developed by the Russians on their earlier space stations, is essentially a pair of pants that sucks fluids down to the legs, simulating the situation normally found on Earth, and thus reduces the fluids in the upper body sooner than landing. Second, doing exercises simulating lower weight loads apparently helps the Russians as well.

Endurance successfully splashes down, returning 4 astronauts after a 6 month mission

11:50 pm

Capitalism in space: SpaceX’s Endurance spacecraft successfully splashed down tonight off the coast of Florida, bringing home four astronauts after a six month mission on ISS.

This event capped a remarkable month for SpaceX. It launched two manned missions to ISS (one of which was entirely private) while returning two (including that private mission after seventeen days). In between the company also launched three Falcon 9 rockets putting satellites into orbit. All told, in the four weeks since the April 8th launch of the Axiom private manned mission to ISS, SpaceX completed five launches, all of which successfully landed the first stages for later reuse.

More important, everything on every one of those launches and splashdowns went like clockwork, with no problems, delays, or glitches. The only thing that delayed anything was the weather, something no one can do anything about.

Rocket engineering is hard, maybe the hardest technical challenge facing humans. The high quality of SpaceX’s work however is beginning to make it seem routine.

Berger: The media should ignore Rogozin

8:56 am

Eric Berger today beat me to the punch with a very cogent op-ed outlining how the press is consistently being fooled by the head of Roscosmos, Dmitry Rogozin, by reporting what he says without really understanding any of the larger context.

It happened again this weekend. Both Bloomberg and Axios reported that Russia is quitting the International Space Station due to sanctions imposed by the United States on Russia. Each of these stories garnered considerable attention. And each of these stories was also wrong.

…Specifically, this is what Rogozin said on state television this weekend: “The decision has been taken already, we’re not obliged to talk about it publicly. I can say this only—in accordance with our obligations, we’ll inform our partners about the end of our work on the ISS with a year’s notice.”

This may sound ominous, but that is the wrong interpretation of Rogozin’s words. There is actually some positive news in there, with Rogozin saying Russia will give NASA and its other partners a full year’s notice before departing. This is more than enough time for NASA and its commercial partners, Northrop Grumman, SpaceX, and Boeing, to work together to salvage the larger Western segment of the space station.

Rogozin’s most recent comments are even more positive than his comments in early March, when he threatened to break off the ISS partnership by the end of the month.

The ignorance of both the Bloomberg and Axios reports were amplified in that they were reporting nothing new, as Rogozin had essentially revealed this decision three weeks earlier.

The bottom line is that Russia is facing the death of its space program. It doesn’t have the cash to finance its own space station, and it has no one else to fly with. China says it will be glad to work with Russia on its Tiangong station, but it isn’t going to put out one dime to help pay for Russian efforts. Nor will the future American private stations.

Thus, most of what Rogozin says is bluster, not to be taken too seriously. Russia is going to stay with ISS for at least the next two years, and if it eventually decides to continue the partnership through ’30 it will be no surprise.

Axiom signs deal with the UAE to fly one astronaut to ISS in ’23

10:52 am

Capitalism in space: Axiom announced today that it has signed an agreement with the United Arab Emirate (UAE) to fly a UAE astronaut to ISS in ’23 for a six month mission.

Axiom was able to put its own passenger on this flight because of a complex deal with NASA that had Axiom act as the go-between for Mark Vande Hei’s launch on a Soyuz in April ’21. Axiom brought the flight for NASA (which didn’t have the funds), and got in exchange a free seat for a passenger on a later American launch. Axiom has now sold that seat to the UAE.

The UAE in turn solidifies its space effort, with a six month manned mission to ISS.

The deal also demonstrates the priceless value of leaving ownership to American companies. Axiom made this deal to sell globally its long term space station plans, and it will use a SpaceX Dragon capsule and Falcon 9 rocket to launch it. Both companies thus make money on their products, instead of the cash going to NASA. Such profits will only encourage further sales, not only to these companies but to other competing American rocket and space station companies.

SpaceX’s Freedom spacecraft docks with ISS

9:15 am

Capitalism in space: As planned SpaceX’s Freedom capsule successfully docked with ISS last night, delivering four NASA astronauts to ISS for a five-month mission.

This launch was the sixth manned flight to ISS by SpaceX, and the seventh overall, with two of those seven launches entirely commercial and paid for by private customers. It appears that, based on already announced plans, that ratio between government and private customers should continue during the next few years, though beyond that expect the private launches to eventually outpace the government ones. When that begins to happen SpaceX might decide to expand its fleet from the four capsules (Endeavour, Resilience, Endurance, and Freedom) it presently operates.

Watch first flight of SpaceX’s fourth capsule, Freedom, carrying four NASA astronauts

10:23 pm

The next launch of a NASA crew to ISS is scheduled to occur tonight at 3:52 am (Eastern) using SpaceX’s new capsule, Freedom, the fourth in the company’s fleet of manned spacecraft. Note too that the first stage of this Falcon 9 rocket will be making its fourth flight into space.

I have embedded the live stream below. As I write this, at 1:19 am (Eastern) the crew has just entered the capsule. Go here for details about the flight, which will be a five month mission.

Commander Kjell Lindgren, veteran of one previous expedition on the space station, leads the four-person crew awaiting liftoff Wednesday. He will be joined by pilot Bob Hines and mission specialist Jessica Watkins, two first-time fliers from NASA’s astronaut corps. European Space Agency astronaut Samantha Cristoforetti, a native of Italy who spent nearly 200 days in orbit in 2014 and 2015, rounds out the crew.

If the launch goes well, Freedom will dock with ISS about sixteen hours later.

If you watch, I must once again note that every person you see aiding the astronauts will be a SpaceX employee. Except for some of the announcers and NASA’s mission control for operating ISS, the launch mission control and everything else is run by this privately owned commercial company.

Return of Axiom mission delayed again because of weather

9:16 am

Because of marginal winds at the splashdown points, SpaceX, Axiom, and NASA agreed today to delay the return of Axiom’s first private mission to ISS one more day.

The Axiom Mission 1 (Ax-1) crew is now targeting to undock from the International Space Station 8:55 p.m. EDT Sunday, April 23.

Weather permitting, the Ax-1 crew is targeted to close the hatch at about 6:45 p.m. Sunday, April 24, to begin the journey home in SpaceX Dragon Endeavour with splashdown off the coast of Florida approximately 1:00 p.m. Monday, April 25.

This delay will also delay the launch of NASA’s next crew to ISS on SpaceX’s new Dragon capsule, Freedom, now scheduled for launch no earlier than April 27th.

New schedule announced for landing of AX-1 crew and launch of NASA crew

9:17 am

Because of poor weather at the splashdown points on Earth, SpaceX and NASA have worked out a new schedule for both the landing of Axiom’s first passenger flight to ISS as well as NASA’s next launch of astronauts.

The integrated NASA, Axiom Space, and SpaceX teams have agreed on a plan for the Axiom Mission 1 (Ax-1) crew to undock from the International Space Station at 8:35 p.m. EDT Saturday, April 23, for a splashdown off the coast of Florida about 1:46 p.m. Sunday, April 24. The decision was made based on the best weather for splashdown of the first private astronaut mission to visit the International Space Station and the return trajectory required to bring the crew and the SpaceX Dragon Endeavour spacecraft back to Earth safely.

…The departure of Dragon Endeavour from the space station will clear the docking port for the arrival of Dragon Freedom and NASA’s SpaceX Crew-4 astronauts. The earliest potential launch opportunity for the Crew-4 mission is 4:15 a.m. Tuesday, April 26, with additional opportunities Wednesday, April 27, and Thursday, April 28. These launch opportunities are undergoing a more detailed program review to ensure they align with integrated operational timelines. The teams want to provide a two-day gap after Ax-1 return for data reviews from splashdown and to prepare for the Crew-4 launch, including the staging of recovery assets.

If the landing occurs on April 23rd as now planned, the Axiom passengers will have spent fifteen days in space, about four more than originally planned.

Axiom again cancels return of manned mission due to weather

9:12 am

Capitalism in space: Because of continuing poor weather on Earth, SpaceX & Axiom once again canceled the planned return of manned mission yesterday.

At the moment there is no word on when SpaceX’s Endeavour capsule will undock and bring its passengers home. Since a NASA crew is preparing for launch on Saturday, April 23rd, we should expect that return to occur beforehand.

This article from Israel about the delay, which also focuses on the flight of Israeli businessman Eytan Stibbe, had this interesting tidbit:

Businessmen Stibbe, American Larry Connor of Ohio, and Canadian Mark Pathy have paid $55 million apiece for the rocket ride. The visitors’ tickets include access to all but the Russian portion of the space station. [emphasis mine]

When the Russians launched Dennis Tito and other tourists in 2000s, I am unsure if those tourists were allowed in the American portion of the station. My guess would be yes, but that would be a guess, and very easily wrong. During the two tourist flights to ISS in October and December it is also unclear if those passengers had access to the American half. Considering the competition for tourist flights that now exists, I would suspect no.

Return of first Axiom commercial crew from ISS delayed

8:55 am

Capitalism in space: Because of iffy weather at their planned splashdown point, SpaceX and Axiom have delayed the return of Axiom’s first commercial crew at ISS so that they will splashdown tomorrow.

Weather permitting, the four-member private astronaut crew now is targeted to undock at about 10 p.m. Tuesday, April 19, to begin the journey home with splashdown off the coast of Florida no earlier than approximately 3:24 p.m. EDT Wednesday, April 20.

If weather remains an issue, the return to Earth of Endeavour could be delayed further.

Boeing and NASA set May 19th for second Starliner unmanned demo launch

10:21 am

NASA yesterday announced May 19th as the new launch date for Boeing’s second attempt to complete the first unmanned Starliner demo mission to ISS.

The uncrewed mission will test the end-to-end capabilities of the Starliner spacecraft and Atlas V rocket from launch to docking and return to Earth at one of five designated landing zones in the western United States. Following a successful completion of the OFT-2 mission, NASA and Boeing will determine a launch window for NASA’s Boeing Crew Flight Test (CFT), Starliner’s first flight with astronauts aboard.

The first unmanned demo flight in December 2019 failed to dock with ISS and had to be cut short due to serious software issues. The launch of the second unmanned demo flight was scrubbed mere hours before launch in August of 2021 due to serious valve issues.

Thus, Boeing’s manned capsule is more than two years behind schedule. Not only has Boeing had to pay more than $400 million for a second demo mission, the delays have caused a lot of business with NASA and with tourists to instead go to SpaceX. Hopefully, the company has finally fixed all issues and will succeed and begin manned operations later this year.

Russia backs off its threats to leave ISS partnership

10:19 am

In several short news posts on Russia’s state-run press today, the Putin government indicated that it has backed off from its threats to end the partnership at ISS quickly.

First, Roscosmos’s head, Dmitry Rogozin, announced that it will proceed with its barter deal with NASA and allow astronauts from NASA and others to fly on Soyuz while Russian astronauts fly on Dragon and eventually Starliner.

“Why give up something that is useful? Anna Kikina [Russian woman cosmonaut] flew to Houston (USA) to familiarize herself with the design of the modules of the ISS American segment and the Crew Dragon spacecraft whose crew she may join. On our part, we are not ruining anything and keep to preliminary accords, although we continue waiting for the government’s decision on the program of cross flights,” Rogozin explained.

Second, Rogozin made statements that suggested Russia will maintain its full partnership on ISS through ’24, and maybe beyond.

Now Russia has to set up its mind about the year until which it cooperates on the ISS project, Rogozin said. “Yes, the Americans want it [cooperation] to last until 2030. The previous talks said that it would be until 2028. But let me repeat again that we have to decide on the main thing: to continue cooperation on the ISS or switch to the ROSS [Russian Orbital Service Station]. Subsequently, we will decide on what to do with our two new modules on the ISS that we docked last year,” Rogozin said.

In other words, Russia ain’t going no where. It might decide eventually to launch a new core module for their own station, and then transfer the newer modules on ISS to it, but none of this will happen until a final date for ISS’s deorbit is established.

Based on Rogozin’s earlier bombastic threats, I had expected Russia to take a harder position. It appears cooler heads in Roscosmos convinced Rogozin and Putin that in terms of cost and safety, a quick exit made no sense.

This decision to back off was also probably influenced by Russia’s losses in the Ukraine. It is no longer in a strong negotiating position in anything, has lost almost all its economic partnerships with the west, and thus does not wish to lose the one partnership that remains, on ISS.

SpaceX successfully launches Axiom’s first commercial flight to ISS

8:19 am

Capitalism in space: SpaceX today successfully launched the first commercial mission to ISS by the private company Axiom, carrying three passengers and one Axiom astronaut as commander.

The replay of the live stream of the launch is embedded below.

The first stage, which landed successfully on the drone ship in the Atlantic, completed its fifth flight. The capsule Endeavour was making its third flight. This is also the second private manned mission launched by SpaceX.

Docking with ISS is scheduled for early tomorrow morning.

All in all, it was a perfect launch, on time and as planned. This has become so routine for SpaceX that we tend to take it for granted. We shouldn’t. Launching people into space remains one of the hardest things humans do, and will likely always be so.

The leaders in the 2022 launch race:

13 SpaceX
9 China
5 Russia
2 ULA
2 Rocket Lab

The U.S. now leads China 20 to 9 in the national rankings.

Rogozin tweets: ISS cooperation to end

5:59 pm

Dmitry Rogozin, the head of Russia’s aerospace corporation, Roscosmos, today confirmed in a series of tweets that Russia intends to end its partnership at ISS due to the sanctions imposed on Russia due to its invasion of the Ukraine.

Rogozin however did not provide any details other than saying:

Specific proposals of Roscosmos on the timing of the completion of cooperation within the framework of the ISS with the space agencies of the United States, Canada, the European Union, and Japan will be reported to the leadership of our country in the near future.

I predict the following:

1. No more barter flights, exchanging Russian and international astronauts on each other’s capsules.
2. No more mutual research on the station.
3. Russia leaves as of ’24, after it adds its remaining modules.

Once those extra modules are launched and installed on the Russian half of ISS, Roscosmos will be more capable of separating its half from ISS and fly it independently. There will be engineering challenges, but this plan will give them two years to address them. It will also give everyone else the time necessary to plan for that separation.

Soyuz capsule returns three astronauts safely, completing Mark Vande Hei’s 355 day mission

8:28 am

A Russian Soyuz capsule successfully returned three astronauts back to Earth today, thus completing Mark Vande Hei’s 355 day mission, the longest so far achieved by an American astronaut.

Vande Hei’s record is the fifth longest overall, behind four other Russians on Mir. Musa Manarov and Vladimir Titov were the first to complete a year-long flight in 1987-1988. Sergei Avdeyev’s flight of 381 days on Mir in 1998-1999 is the second longest. Valery Polyakov holds the record for the longest flight, 437 days in 1994-1995.

Now that Vande Hei is safely back on Earth, expect Dmitry Rogozin, the head of Roscosmos, to make some announcement in the next day or so further limiting cooperation at ISS. It is my expectation he will end the discussions between Roscosmos and NASA to exchange one-for-one flights on each other’s capsules. While the partnership to maintain and occupy ISS will continue, Rogozin will likely end any cooperation otherwise.
