With all the talk about the current set of astronauts returning early from the International Space Station (ISS) due to medical issues as well as last year’s issue with Chinese astronauts stuck on their station, it is hard to keep track of who is in space these days.
Hence, you may want to stay up to date on those floating in space by using this website – https://whoisinspace.com/. As of today, there are 10 humans in space – 6 on the ISS (3 from the US, 3 from Russia, and 1 from Japan) and 3 on China’s Tiangong space station.
As shown in the image above, the site also gives some stats on the crews, such as the mission that brought them to the station as well as each person total amount of time in space.
Just think of it as a Who’s Who listing for low Earth orbit.
“NASA is postponing the Thursday, Jan. 8, spacewalk outside the International Space Station. The agency is monitoring a medical concern with a crew member that arose Wednesday afternoon aboard the orbital complex. Due to medical privacy, it is not appropriate for NASA to share more details about the crew member. The situation is stable. NASA will share additional details, including a new date for the upcoming spacewalk, later.”
–Statement on NASA’s website regarding a spacewalk that was to take place tomorrow outside the International Space Station (ISS). The planned spacewalk, which was to fix a solar array and last for six and a half hours, involved astronauts Mike Fincke and Zena Cardman. It would have been Cardman’s first and Fincke’s tenth spacewalk.
Update: The four astronauts that are part of Crew-11 on the ISS will be returning to Earth earlier than planned because of health issues. According to NBC News, the matter relates to a single astronaut with a medical condition who is currently in stable condition.

Santa’s gift-giving territory is pretty wide, but it is not clear whether he will make it to the International Space Station (ISS). However, the astronauts are ready if he does show up. They have hung their space boots by the airlock with cheer.

Here are some recent space-related stories of interest.
For several years now, in discussing plans for its human spaceflight program beyond the International Space Station, Russian officials would proudly bring up the Russian Orbital Station, or ROS…Oleg Orlov, director of the Institute of Biomedical Problems of the Russian Academy of Sciences, said ROS will no longer be composed of entirely new modules. Rather, its core will be the Russian segment of the International Space Station. “The Scientific and Technical Council of Roscosmos supported this proposal and approved the deployment of a Russian orbital station as part of the Russian segment of the ISS,” Orlov reportedly said.
NASA is losing critical communication links with its Mars missions. After recently losing contact with the MAVEN spacecraft, the agency faces the impending loss of the Mars Odyssey orbiter, which has been circling the Red Planet for over two decades. As both orbiters approach the end of their operational lifespans, NASA will soon have to find ways to maintain data relay capabilities for its rovers and other missions on the fourth planet.
A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data suggests a more complicated picture: Titan’s interior is more likely composed of ice, with layers of slush and small pockets of warm water that form near its rocky core. Led by researchers at NASA’s Jet Propulsion Laboratory in Southern California and published in the journal Nature on Wednesday, the new study could have implications for scientists’ understanding of Titan and other icy moons throughout our solar system.

Just as Jared Isaacman, NASA’s new Administrator, started to settle into his new post, the White House updated the nation’s space priorities.
Returning to the Moon by 2028, and the establishment of initial elements of a permanent lunar outpost by 2030;
Deploying of nuclear reactors on the Moon and in orbit, including a lunar surface reactor ready for launch by 2030; and
Spurring private sector innovation and investment by upgrading launch infrastructure and developing a commercial pathway to replace the International Space Station by 2030.
Adding nuclear reactors as its own goal seems a little odd since it could simply be wrapped into the first goal related to a permanent lunar outpost, but maybe this is just to kick regolith into the eyes of the Chinese who announced a similar intention.
Returning to the Moon by 2028 will certainly be a challenge, but luckily Administrator Isaacman is showing no favorites when it comes to meeting this goal. This week he made this statement about plans to return to the Moon:
I don’t think it was lost on either vendor that whichever lander was available first to ensure that America achieves its strategic objectives on the moon is the one we were going to go with.
His friend Elon Musk was certainly listening, but so far we have not heard him say that the new NASA Administrator has a 2 digit IQ. Of course, it has only been a few days, though the honeymoon is likely to be very short.
