The first hibernation studies with human subjects could be feasible within a decade, a European Space Agency (ESA) researcher thinks.

Such experiments would pave the way for a science-fiction-like approach to long-duration space missions that would see crew members placed into protective slumber for weeks or months on their way to distant destinations.

Hibernating on a year-long trip to Mars would not just prevent boredom in a tiny space capsule; it would also save mission cost, as the hibernating crew members wouldn't need to eat or drink and would even require far less oxygen than those awake. There are other, rather odd benefits of hibernation, as well. Research in animals suggests that bodies of hibernating astronauts might waste away much less than the bodies of those awake in microgravity. Upon arrival, these hibernators would thus be fit and ready to commence challenging exploration almost straight away after regaining consciousness.

For all these reasons, hibernation, also known as torpor, has long been a staple of sci-fi space movies. From "Alien" to "2001: A Space Odyssey," fictional space travelers have crossed vast distances cocooned unconscious inside high-tech pods while AI machines and android robots keep their spacecraft on a steady course.

Now Live: Artemis I launch with Astronaut Kayla Barron.

Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars.

Space health: The dark side of multiple spaceflights on human brain structure Spaceflight experience, in particular longer missions and shorter inter-mission recovery time, induce fluid changes in the brain that may not return to normal before subsequent flights, reports a study published in Scientific Reports. Ventricles — cavities in the brain filled with cerebrospinal fluid — expand increasingly with longer spaceflight missions up to six months, and inter-mission intervals of less than three years may not allow sufficient time for the ventricles to fully recover. Spaceflight induces widespread changes in the human brain including ventricle volume expansion, but it is unclear if these changes differ with varying mission duration or number of previous spaceflight missions. Rachael Seidler and colleagues scanned the brains of 30 astronauts using MRI, pre- and post-spaceflight, including those on two-week missions (eight astronauts), six-month missions (18 astronauts) and longer (four astronauts). They found that longer spaceflight missions resulted in greater ventricular enlargement, which tapered off after six months in space. The authors found that for 11 astronauts who had more than three years to recover in between missions, there was an associated increase in ventricle volume after their most recent mission. However, the authors found that in seven astronauts who had a shorter recovery time in between missions there was little to no enlargement of the ventricles post-flight compared to pre-flight. They propose that less than three years between spaceflights may not be enough time to allow ventricles to recover their compensatory capacity to accommodate the increase in intracranial fluid and they remain enlarged when the astronauts return to space within this time frame. As spaceflight becomes more frequent and of longer duration, the findings provide insight into how spaceflight experience, both previous and current, may influence brain changes. The authors conclude that their findings can help to improve guidance for future mission planning.

NASA announced the crew for Artemis II: Christina Koch, Jeremy Hansen, Victor Glover, and Reed Wiseman. The mission will probably launch in 2025 (it’s currently scheduled for no earlier than November 2024). Here’s a rundown of what the mission will do (and what it won’t, which is land on the moon).

Chinese Astronauts Performed Emergency Space Station Repairs Following Debris Impact

China’s space station crew carried out two spacewalks this past winter to repair the solar wings attached to the core module, which had been damaged by space debris. Taking out the Trash (in Space) The Tiangong space station’s core module, Tianhe, suffered a partial loss of power due to the impact, leading China to dispatch its astronauts on a pair of spacewalks for orbital repairs.

63th anniversary of the first Human Space fight.

63 years ago, on April 12, 1961, all radio stations on Earth interrupted their broadcasts to report sensational news - a man in space!

ROSCOSMOS is also placing orders for the development, manufacture and supply of space equipment and space infrastructure objects. The state corporation is also responsible for international space cooperation and tasked with setting the stage for the future use of results of space activities in the social and economic development of Russia.

The group will fly aboard NASA's Orion spacecraft as part of the Artemis program, which aims to return astronauts to the surface of the Moon for the first time in more than 50 years, establish a long-term presence on the lunar surface and eventually put humans on Mars.

The four-person crew will include NASA astronauts Christina Hammock Koch, Victor Glover and Reid Wiseman as well as Canadian astronaut Jeremy Hansen.

"We have a lot to celebrate, and it's so much more than the four names that have been announced. We need to celebrate this moment in human history," said Glover, Artemis II's pilot, during a Monday morning event to announce the crew. "Artemis II is more than a mission to the Moon and back. It's more than a mission that has to happen before we send people to the surface of the Moon. It is the next step on the journey that gets humanity to Mars."

Meet Sophie Adenot, one of the new ESA career Astronauts. Born in 1982 in France, she seems to have done everything right to get in this position. After studying spacecraft dynamics in France, she did a master of science at MIT specifically on centrifuge training for astronauts.

Right after she joined the France Air Force to become a helicopter pilot. In this role she worked as search and rescue pilot, formation flight leader, team captain and as experimental test pilot.

Sophie has received multiple distinctions for her work as young leader and her outreach for gender equality.

Can't wait to see her float in Space!

NASA Suspend ISS Spacewalks, Spacesuits Leaking Water

NASA Suspend ISS Spacewalks, Spacesuits Leaking Water

There have been more than 200 spacewalks outside the ISS since it launched in 1998.Picture: NASA It might be time for NASA to ditch its aging ISS spacesuits. The space agency announced a pause to all its spacewalks until it has a better handle on a lingering and frightening issue that’s causing water to leak inside of astronauts’ helmets. The latest incident happened during an extravehicular…
