Dragon docks with ISS; astronauts reveal its name is Endeavour

Capitalism in space: SpaceX’s first manned Dragon capsule successfully docked today with ISS.

A few hours after launch the two American astronauts, Doug Hurley and Bob Behnken, also revealed that they had named the capsule “Endeavour.”

I know this is really old news from late last night and early this morning, but I was out on a cave trip (taking a work break to have some fun underground for the first time in three months). I post it for completion. I also know that the live stream of these events was active here all day for my readers to follow things, as they happened.

Prepare for even more increasing space excitement in the coming years. The Trump administration increasingly is shifting NASA’s gears to have private companies build its spaceships and rockets and science instruments. The more they do this, the less expensive and the more capabilities we shall have as a nation. This success will be a challenge for other nations to match, which in turn will raise the stakes and increase the competition, the excitement, and the action in space.

Yes, the 20s I hope are going to roar, at least in space.

SpaceX’s first manned Dragon launch scrubbed due to weather

UPDATE: They were forced to scrub at T-16:54 because of weather. They will try again in three days on May 30th, at 3:22 pm (Eastern). I will post the live stream here on Behind the Black late Friday night.

Original post:
—————————-
I have embedded below SpaceX’s live stream of the first manned Dragon mission, set to launch at 4:33 pm (Eastern). The stream begins at about 12:15 pm (Eastern). Feel free to watch as the day unfolds. Sadly, it is being managed by NASA, not SpaceX, and thus is filled with a lot of the agency’s fake hype.

I have also set it to remain at the top of the page until after the launch, or if it is scrubbed.

On a side note, NASA is now aiming for an August 30 launch of SpaceX’s next manned Dragon mission, the first official operational flight.

Below the fold I am also posting images captured, with some commentary.

SpaceX successfully completes static fire dress rehearsal of manned Dragon Falcon 9

Capitalism in space: SpaceX today successfully completed its standard static fire dress rehearsal prior to launch of the Falcon 9 rocket that will place the first manned Dragon capsule, carrying two astronauts, into space on May 27th.

Today NASA also gave its final okay for the launch. It is now set to happen.

Almost lost: The flag that SpaceX astronauts will claim on ISS

The American flag that flew on the first and last shuttle mission and was left on ISS for the next crew flown on an American spacecraft to claim apparently went missing during the decade since the last American shuttle flight, and took several weeks of searching in 2018 for astronauts to find it.

“We looked and looked and looked,” said Tingle. “I talked to my fellow astronauts that were on board the ISS and everybody had a little bit of a different memory on where it could be or where it might be. So we spent probably three or four weeks just kind of scouring in our spare time, trying to find it.”

They did find it, and now it awaits the arrival of the two-person crew of SpaceX’s Dragon capsule, Bob Behnken and Doug Hurley, set to launch on May 27th, the first Americans to launch from American soil on an American rocket in an American spacecraft in almost a decade.

More important: This will be the first flight of any Americans on a private rocket and spacecraft, built and owned by a private commercial company instead of the government. For the capitalistic and free United States, it marks the end of a half century of a government-run Soviet-style space program and a return to capitalism and freedom.

Japan launches HTV cargo ship to ISS

Japan today successfully launched to ISS the last of its first generation HTV cargo ships.

This was the ninth such cargo ship launched by Japan. The mission was also the last launch of Mitsubishi’s H-2B rocket, Japan’s most powerful. It is being replaced with the H-3 rocket, which they hope to fly for the first time before the end of this year. They also hope that the H3 will be cheaper to operate, and will allow Mitsubishi to garner some commercial business with it, something they failed entirely to do with the H-2B.

This was also Japan’s second launch in 2020, which means they remain outside the leaders in the 2020 launch race:

8 China
6 SpaceX
6 Russia
3 ULA

The U.S. continues to lead China 11 to 8 in the national rankings.

NASA signs deal with Russians for one Soyuz seat to ISS

Citing a need to provide some back-up in case there are more delays getting the American manned capsules being built by SpaceX and Boeing into operation, NASA yesterday announced that it has signed a deal with Roscosmos to buy one seat on the October Soyuz launch to ISS.

The statement did not disclose the value of the deal, but NASA spokesman Josh Finch told SpaceNews the agreement is valued at $90.25 million. That includes the seat on the Soyuz spacecraft and various training, pre-launch and post-landing services. In addition, Finch said that NASA will compensate Roscosmos for bumping a Russian cosmonaut off that Soyuz mission by flying an unspecified amount of Russian cargo to the station on NASA commercial cargo spacecraft.

I wonder if there are other political reasons behind this deal, besides insuring American access to ISS. $90 million is a lot of money to the Russians, and considering their impending loss of income from NASA (with us no longer buying Soyuz seats in the future) as well as their loss of most of their commercial launch business, it could be that NASA managers wanted to shore up Roscosmos’s financial situation. Remember, at NASA there are many who swear a greater loyalty to space operations from all countries, even at the expense of the United States.

Russia launches Progress freighter to ISS

Russia tonight successfully launched a new Progress freighter to ISS using its Soyuz-2 rocket.

The U.S. now leads both China and Russia 10 to 6 in the national rankings. This is the first time that Russia has been able to keep up with China in launches in several years. Since China had expected to launch more times than Russia in 2020, this suggests that China’s launch rate has been reduced because of the Wuhan flu. It at least appears that many of their smaller launch rockets have suspended launches.

We have also heard nothing recently about China’s planned mid- to late-April first launch of its Long March 5B. With only six days left in the month, one wonders if this launch too has been delayed.

New changes to the brain found from long space missions

Scientists have discovered a “significant increase” in the brain’s white matter that occurs after astronauts have completed long missions in weightlessness.

The team conducted brain MRIs of 11 astronauts before they traveled to the ISS, and then again one day after they returned. Scans were then performed at several interval across the following year. “What we identified that no one has really identified before is that there is a significant increase of volume in the brain’s white matter from preflight to postflight,” Kramer says. “White matter expansion in fact is responsible for the largest increase in combined brain and cerebrospinal fluid volumes postflight.”

These changes remained visible one year after spaceflight, which the researchers say indicates they could be permanent alterations. Past research has suggested that changes in the volume of cerebrospinal fluid (CSF) specifically could be a key driver of Visual Impairment Intracranial Pressure in astronauts. The authors of the new study also observed an increase in the velocity of CSF through the cerebral aqueduct, along with deformation of the pituitary gland, which they believe is related to higher intracranial pressure in microgravity.

The uncertainties for this work remain very large. For one thing, the sample (11 astronauts) is very small. For another, the permanence of this change is only suggested and remains unproven.

Nonetheless, this research adds to the growing body of research that suggests that long term weightlessness is generally not good for the human body. It also reinforces the desperate need for research into the effects of even a small amount of artificial gravity. To most efficiently design spacecraft that provide some form of centrifugal force as artificial gravity, we need to find out the minimum required. It could be providing only 10% or 30% Earth gravity could be sufficient. Or not. We just don’t know.

The engineering challenges however go up significantly the more gravity you need to create. For future interplanetary travel this information is critical.

First manned Dragon mission slips to end of May

Capitalism in space: According to NASA administrator Jim Bridenstine, the first manned flight of SpaceX’s Dragon capsule will now occur at the end of May, not mid-May, and will last two or three months.

“I think we’re really good shape,” Bridenstine said in an interview Thursday. “I’m fairly confident that we can launch at the end of May. If we do slip, it’ll probably be into June. It won’t be much.”

The article at the link also reveals that the two astronauts will spend between two to three months on board ISS, not two weeks as originally planned.

Russia confirms launch delay to 2021 of Nauka module to ISS

Dmitry Rogozin, the head of Russia’s space agency Roscomos, confirmed yesterday that the launch of its Nauka module for ISS will not occur in 2020.

In January they had hinted that the mission would be delayed to early 2021.

Construction of Nauka had begun in 1995, twenty-five years ago, which in a sense puts it in the lead for the most dismal government space project, beating out the James Webb Space Telescope (about 21 years since first proposed) and the Space Launch System (16 years since Bush proposed it). All three now say they will launch in 2021 but no one should be criticized if they doubt this.

NASA selects full crew for first operational Dragon mission

Even though SpaceX’s first demonstration manned mission to ISS has not yet occurred, NASA yesterday announced the selection of the full four person crew for the second flight, set for later this year and intended as the first operational mission to ISS, lasting six months.

This announcement tells us several things, all good. First, it appears NASA has now definitely decided that the demo mission, presently scheduled for mid-May, will be a short-term mission. They had considered making it a six-month mission, but it now appears they have concluded doing so will delay the demo launch too much.

Second, that NASA is solidifying its plans for that operational flight, the second for Dragon, including a tentative launch date later in 2020, is further evidence that they intend to go through with the demo mission in mid-May.

Finally, it appears that NASA has decided that it will not buy more seats on Russian Soyuz capsules, something that they had previously hinted they needed to do because the agency was worried the American capsules would not be ready this year. The article describes the negotiations on-going with the Russians about the use of Dragon, as well as the future use by Americans of Soyuz. NASA wishes to have astronauts from both countries fly on both spacecraft (Starliner too, once operational), but Russia is as yet reluctant to fly its astronauts on Dragon. They want to see that spacecraft complete more missions successfully.

Regardless, future flights of Americans on Soyuz will cost NASA nothing, as the agency wishes to trade the seats on the U.S. capsules one-for-one for the seats on Soyuz. It also means that NASA has decided it doesn’t need to buy Soyuz flights anymore, as it now expects Dragon to become operational this year.

NASA confirms May target date for first manned Dragon flight

Capitalism in space: In announcing today it is beginning media accreditation for SpaceX’s first manned Dragon flight to ISS, the agency confirmed earlier reports from SpaceX that they are now aiming for a mid-to-late May launch.

Much can change before then. COVID-19 could get worse, shutting down all launches. The engine failure on yesterday’s successful Falcon 9 launch could require delays.

However, right now, things look good for May, which will be the first time since 2011 that Americans will launch from American soil on an American-built rocket, an almost ten year gap that has been downright disgraceful. Thank you Congress and presidents Bush and Obama! It was how you planned it, and is also another reason we got Trump.

Manned Dragon mission targeted for May

Capitalism in space: According to one SpaceX official, they are now aiming for a May target date for their first manned Dragon mission to ISS, even as they will maintain a launch pace of one to two launches per month.

SpaceX president and chief operating officer Gwynne Shotwell [said] that she expects at least one to two launches per month in the near future, whether they be for customers or for SpaceX’s own internet-satellite constellation, Starlink. “And we are looking at a May timeframe to launch crew for the first time,” Shotwell continued. That launch, called Demo-2, will send NASA astronauts Bob Behnken and Doug Hurley to and from the International Space Station (ISS) aboard SpaceX’s Crew Dragon capsule.

At that pace SpaceX will complete between 12 to 24 launches for the year. They had predicted they would complete 21, so this is in line with that prediction.

The last cargo Dragon to berth with ISS using robot arm

Astronauts yesterday used the robot arm on ISS to berth SpaceX’s cargo Dragon freighter, the last time a Dragon capsule will be berthed to the station in this manner.

The successful supply deliver marked the 20th time a SpaceX Dragon cargo capsule has arrived at the space station since May 2012. The mission, known as CRS-20 or SpaceX-20, also the final flight of SpaceX’s first-generation Dragon spacecraft, which the company is retiring in favor of a new Dragon capsule designed to dock directly with the space station without needing to be captured by the robotic arm.

I could put this another way that is more embarrassing to NASA. After twenty flights, the agency has finally admitted that SpaceX can design a spacecraft that can do automatic dockings, and is now willing to allow it.

That of course is a gross simplification. Nonetheless, the successful unmanned demo flight last year of SpaceX’s crew Dragon, docking directly with ISS, has proven SpaceX can do it. And since that crew Dragon is essentially the same design for SpaceX’s future cargo Dragons, it makes sense to shift from robot-arm-berthing to direct docking for all future Dragon flights.

Axiom and SpaceX sign deal for flying commercial tourists to ISS

Capitalism in space: Axiom, the commercial company that already has an agreement with NASA to build its own commercial modules for ISS, has signed an agreement with SpaceX to use its crew Dragon capsule to ferry one professional and three tourists to ISS, as soon as the second half of 2021.

The private crew members will spend at least eight days on the orbiting research platform, allowing them to enjoy “microgravity and views of Earth that can only be fully appreciated in the large, venerable station,” Axiom said in a statement.

Axiom said Thursday it has signed a contract with SpaceX to transport a commander “professionally trained” by Axiom and three private astronauts to the space station on a Crew Dragon spacecraft. The mission could take off as soon as the second half of 2021, Axiom said.

This is SpaceX’s second commercial customer for its Dragon capsule. Two weeks ago it signed a deal with Space Adventures to fly four tourists on a crew Dragon for up to five days.

NASA leaning towards long-duration flight for 1st Dragon mission

Capitalism in space: According to one former astronaut as well as a review of photos of the training being given to the astronauts who will fly on SpaceX’s first manned Dragon flight, this Space News article thinks that NASA will make that first flight a long-duration mission.

This Dragon demo mission is officially still planned as a short mission, no more than two weeks. To extend it requires additional training, which the photos appear to show, and would thus delay its launch by as yet an unspecified time period.

The article also cites a third reason NASA is now favoring the long-duration option: The issues with Boeing’s manned Starliner capsule:

Another factor in any decision to extend Demo-2 is the status of the other commercial crew vehicle, Boeing’s CST-100 Starliner. That vehicle flew an uncrewed test flight in December, but software problems during the flight, including one which shortened the mission and prevented a docking with the ISS, have raised questions about whether a second uncrewed test flight will be needed. An investigation into those problems is expected by the end of this month.

Even if NASA decides a second uncrewed test flight of Starliner is not needed, a review of all of the spacecraft’s one million lines of code, and other reviews, is likely to delay a crewed test flight of the spacecraft. NASA and Boeing had previously agreed to make that test flight a long-duration mission, with NASA astronauts Mike Fincke and Nicole Mann and Boeing astronaut Chris Ferguson performing space station training in addition to that for the Starliner itself.

The delay in Boeing’s long duration mission leaves a gap in the schedule for maintaining crews on ISS. Flying Dragon long-duration would help solve that.

NASA confirms seriousness of 2nd Starliner software issue

At a press conference today, NASA and Boeing officials confirmed the rumors that there was a second software error during Starliner’s unmanned demo mission in December that might have caused a serious failure had it not been caught on time.

[After the first software error], engineers began reviewing other critical software sequences as a precaution and discovered yet another problem. Software used to control thruster firings needed to safely jettison the Starliner’s service module just before re-entry was mis-configured, set for the wrong phase of flight.

Had the problem not been found and corrected, the cylindrical service module’s thrusters could have fired in the wrong sequence, driving it back into the crew module and possibly triggering a tumble or even damaging the ship’s protective heat shield.

While a detailed analysis was not carried out at the time, “nothing good can come from those two spacecraft bumping back into one another,” said Jim Chilton, a senior vice president for Boeing Space and Launch.

That two different software errors were not caught prior to flight has NASA demanding a complete review of Boeing’s quality control systems. And NASA here is correct. Boeing as a company appears to have fundamental quality control issues up and down the line, in all its projects. A complete review appears warranted.

A Chernobyl fungus that thrives on radiation

Scientists have found that a Chernobyl fungus that eats radiation, turning it into food, is so successful that they have sent samples to ISS to see how it responses to space radiation.

By growing it in the International Space Station, where the radiation level is hiked compared to that on Earth, Venkateswaran and Professor Clay Wang of the University of Southern California were able to monitor mutation. When microorganisms are put under more stressful environments, they release different molecules, which could further out understanding of the fungi and how it can be used to develop radiation-blocking drugs for humans.

It is also possible that the fungus could be adapted for other uses.

Kasthuri Venkateswaran, a research scientist at NASA who is leading the experiments on the Cryptococcus neoformans fungi, believes that by extracting its radiation-absorbing power and manufacturing it in drug form, it could be used as a ‘sun block’ against toxic rays.

It would allow cancer patients undergoing radiation therapy, nuclear power plant engineers and airline pilots to operate without fear of absorbing a deadly dose of rays, Venkateswaran envisaged to Scientific American magazine.

The fungi’s radiation-converting power could also be used to power electrical appliances, with it being touted as a possible biological answer to solar panels.

It appears that the fungi’s high level of melanin contributes to its ability to do this.

ISS crew returns to Earth

Three crew members from ISS returned to Earth today in a Soyuz capsule, including American Christina Koch, who set a new longevity record of 328 for a woman.

Christina Koch launched to the International Space Station aboard the Soyuz MS-12 launch vehicle on 14 March 2019 from the Baikonur Cosmodrome in Kazakhstan. At the time of launch, she was scheduled to perform a six-month mission, returning to Earth on the Soyuz MS-12 vehicle in early October 2019.

However, a variety of factors aligned to place NASA in the position of allowing one of its astronauts to remain aboard the International Space Station for close to one year. Christina was the logical choice given her background and EVA/spacewalk training. The decision, announced just one month after she began living and working aboard the Station for a few months, meant Christina would become the world-wide record holder for longest continuous time in space by a woman.

In fact, with a landing Thursday, Christina will have been in space 328 days, just 12 days shy of fellow NASA astronaut Scott Kelly’s record for single-longest continuous time in space by a NASA astronaut at 340 days.

The overall longevity record still belongs to Russian Valeri Polyakov, at 438 days in 1994-1995.

Why Bigelow passed on NASA bid for new ISS module

Capitalism in space: In an interview this week, Robert Bigelow provided his reasons for not bidding on the NASA agreement to build additional modules for ISS, won by passed on NASA bid for new ISS module, won by Axiom this week.

In a Jan. 28 interview, Robert Bigelow said his company decided not to bid on a NASA competition for access to an ISS docking port for a commercial module because the funding NASA offered for doing so was too low. NASA announced Jan. 27 it selected Axiom Space to use the port through its Next Space Technologies for Exploration Partnerships (NextSTEP) program.

When NASA issued the request for proposal in June for the docking port, NASA said it projected making $561 million available for both the docking port solicitation and a separate one to support development of a free-flying commercial facility. “That was asking just too much” of the company, Bigelow said. “So we told NASA we had to bow out.”

NASA now appears willing to separate the free flyer from the program, meaning that it wishes to make more money available to both, something Bigelow says is necessary because at the moment he believes there are not enough customers outside NASA for any orbital space business to make a profit.

On this last point I think Bigelow might be wrong. I also think it will be a mistake for NASA to provide these companies too much money. Keep them on a tight lease, force them to work efficiently so that they lower costs. This will make it easier for them to charge less to outside customers, thus widening their customer base more quickly.

If NASA gives them a blank check, it will remain the only customer, as the companies will then end up spending too much building their facilities, making it impossible for any other private customer to afford using it.

NASA picks Axiom to build three private commercial modules on ISS

Capitalism in space: NASA today picked the new space station company Axiom to build three modules to ISS, designed to operate as a private commercial operation.

The first segment launch is targeted for 2024. The three segments will include a node with multi-ports, a crew module, and a research module, and will be the “hotel” for private tourists that Axiom hopes to send to ISS two or three times per year. The entire section will also be designed to eventually separate from ISS when that station is retired and operate, with more additions, as an independent station.

This decision did not include the actual contract, only the choice of company to build this new section of ISS. Later negotiations will determine the fixed price amount that NASA will pay.

Why did NASA pick Axiom, which has not yet launched anything, and bypass Bigelow, which has launched two independent test modules and one that has been attached to ISS and working successfully now for several years? This quote explains:

Although Axiom is a relatively young company, having been formed only four years ago in 2016, there is no lack of experience within the company’s ranks.

Axiom’s Co-founder and CEO is Micheal Suffredini, who formerly worked at the Johnson Space Centre (JSC) as the program manager for the International Space Station project.

The Axiom team also includes Michael Lopez-Alegria, a former NASA astronaut who flew on the space shuttle three times and commanded the 14th Expedition to the ISS, as well as former shuttle commanders Brent Jett and Charles Bolden, the latter of whom served as NASA’s 12th administrator from 2009 to 2017.

Axiom is also working alongside several companies with extensive experience with the ISS program, this includes Boeing, who has made several of the modules that make up the US Segment, including Node 1 and the US Laboratory Module. Axiom is also working alongside Thales Alenia Space, Maxar Technologies and Intuitive Machines to get this project off the ground. [emphasis mine]

In other words, it appears it’s not what you know, it’s who you know. This is not to say that the individuals and companies listed above do not know much, but that the company’s real experience with building private modules is lacking. Boeing has built NASA’s modules, but those were for the government and were therefore costly. I have grave doubts they could do this inexpensively, though I could be wrong.

The key will be whether they aim to make their profits from their commercial customers, or use NASA (and the federal government) as their cash cow. The track record of most of Axiom’s partners suggests the latter. For example, Bigelow built and launched its BEAM module to ISS for $17 million, and got it done in three years. We don’t yet know the cost of Axiom’s modules, but their target build-time is already longer, at four to five years

Don’t get me wrong. I applaud NASA’s approach here. They are ceding ownership and construction to a private company, and allowing its work to be commercialized for profit, something that NASA routinely opposed for decades. I just worry that the company it has chosen will be not up to the task, and is not focused on making those profits.

Airbus gets ESA as customer for its ISS commercial platform

Capitalism in space: Airbus has signed up the European Space Agency (ESA) to use its as-yet unlaunched ISS Bartolomeo module as an experimental platform.

The Bartolomeo platform – named after Christopher Columbus’ younger brother – is currently in the final stage of launch preparation at Airbus in Bremen and is scheduled for launch to the ISS in March 2020. Bartolomeo is developed on a commercial basis by Airbus using its own investment funds and will be operated in cooperation with ESA.

The platform can accommodate up to 12 different experiment modules, supplying them with power and providing data transmission to Earth. Bartolomeo is suitable for many different experiments. Due to the unique position of the platform with a direct view of Earth from 400 kilometres, Earth observation including trace gas measurements or CO2 monitoring of the atmosphere are possible, with data useful for climate protection or for use by private data service providers.

This is the European effort to duplicate the slow commercialization of ISS that is also taking place in the U.S., with more and more of the payloads and operating platforms on the station being developed, owned, and operated not by NASA but by private companies.

Launch abort data suggests Dragon performed “flawlessly”

A preliminary review of the data gathered during SpaceX’s launch abort test on January 19, 2020 suggests the system performed “flawlessly”.

The Crew Dragon began its launch escape maneuver at 10:31:25 a.m. EST (1531:25 GMT) — initiated by a low setting of an on-board acceleration trigger — when the Falcon 9 was traveling at a velocity around 1,200 mph (536 meters per second), according to SpaceX.

Eight SuperDraco thrusters immediately pressurized and ignited as the Falcon 9 rocket’s first stage engines were commanded to shut down as part of the abort sequence. The escape engines on the Crew Dragon produced nearly 130,000 pounds of thrust at full power. The SuperDracos performed flawlessly, SpaceX said, accelerating the capsule away from the top of the Falcon 9 at a peak acceleration of 3.3Gs. The SuperDracos accelerated the spacecraft from about 1,200 mph up to more than 1,500 mph (about 675 meters per second) in approximately seven seconds, according to SpaceX.

At this point it appears the only reason the first manned launch might be delayed a bit is if NASA decides to turn it into a long duration mission, requiring new training for the crew.

Russia again delays launch of Nauka module for ISS

Russia yesterday announced that it will once again delay the launch of its Nauka module for ISS due to “additional adjustments that should be carried out due to the use of original propellant tanks.”

The TASS article did not explain what those adjustments will be, though it did outline some of the sad history of Nauka, which Russia had begun construction in 1995, a quarter of a century ago.

Earlier, Roscosmos Director General Dmitry Rogozi said the research module’s original propellant tanks, manufactured about 18 years ago, could be replaced with those from the Fregat booster. However, later it was decided to send the module to the ISS with its original tanks.

The construction of the Nauka module began in 1995. Russia initially planned to launch the Nauka lab to the ISS as a back-up of the Zarya compartment (the station’s first module that continues its flight as part of the orbital outpost) but the launch was numerously delayed. In 2013, the Nauka module was sent to the Khrunichev Space Center after metal chips were found in its fuel system.

Right now they are saying it will probably launch early in 2021, not late in 2020 as previously announced.

Dragon returns to Earth with mice and cookies baked in space

After several months docked to ISS SpaceX’s cargo Dragon returned to Earth today, bringing back forty mice send up in December for research and some cookies that were baked in space.

Researchers want to inspect the handful of chocolate chip cookies baked by astronauts in a special Zero G oven just in time for Christmas. The oven launched to the space station in November, so astronauts could pop in pre-made cookie dough provided by DoubleTree. A spokesman for the hotel chain said five cookies were baked up there, one at a time. The company plans to share details of this first-of-its-kind experiment in the coming weeks. “We made space cookies and milk for Santa this year,” NASA astronaut Christina Koch tweeted late last month from the space station, posing with one of the individually wrapped cookies.

Scientists also are getting back 40 mice that flew up in early December, including eight genetically engineered to have twice the normal muscle mass. Some of the non-mighty mice bulked up in orbit for the muscle study; others will pack it on once they’re back in the lab.

At the moment the only way to get experiments like this back from ISS is with cargo Dragon. Hopefully that will change when Sierra Nevada’s Dream Chaser mini-shuttle finally flies in the next few years.
