What Can Be Done to Help Astronaut Vision in Space?

Spaceflight takes a serious toll on the human body. As NASA’s Twin Study demonstrates, long-duration stays in space lead to muscle and bone density loss. There are also notable effects on the cardiovascular, central nervous, and endocrine systems, as well as changes in gene expression and cognitive function. There’s also visual impairment, known as Spaceflight-Associated Neuro-ocular Syndrome (SANS), which many astronauts reported after spending two months aboard the International Space Station (ISS). This results from increased intracranial pressure that places stress on the optic nerve and leads to temporary blindness.

Researchers are looking for ways to diagnose and treat these issues to prepare for future missions that will involve long-duration stays beyond Earth and transits in deep space. A cross-disciplinary team of researchers led by the University of Western Australia (UWA) has developed a breakthrough method for measuring brain fluid pressure that could reduce the risk of SANS for astronauts on long-duration spaceflights. This research could have applications for the many efforts to create a human presence on the Moon in this decade and crewed missions to Mars in the next.

NASA and Axiom Space Do a Partial Reveal of the Spacesuit That Will be Worn on the Moon

NASA and Axiom Space Inc. provided a first, limited look at the new spacesuits that will be worn by the next astronauts to land on the Moon. The Axiom Extravehicular Mobility Unit (AxEMU) spacesuit that will be worn for the Artemis missions was only partially revealed at an event at Johnson Space Center in Houston, in order not to give away any proprietary information about the suit.

“Since a spacesuit worn on the Moon must be white to reflect heat and protect astronauts from extreme high temperatures,” Axiom Space said in a press release, “a cover layer is currently being used for display purposes only to conceal the suit’s proprietary design.”

Want Artemis to Succeed? Virtual Reality Can Help

Artemis astronauts are returning to the Moon, and they’ll be following in Apollo’s footsteps when they go. But things are different this time. Not only is technology far more advanced, but so is the way we think about technology and how we design it.

A new paper shows how two of modern technology’s offspring— virtual reality (VR) and user-centred design (UCD)—can be brought to bear on the Artemis Program.

Spectacular Night Launch Sends SpaceX Crew 6 to the Space Station

The NASA/SpaceX Crew 6 members are now on their way to the International Space Stations after a spectacular nighttime liftoff from Launch Complex 39A at Kennedy Space Center.

At 12:34 am EST, a SpaceX Falcon 9 rocket sent a Dragon spacecraft named Endeavour into orbit. Onboard were NASA astronauts Stephen Bowen and Warren Hoburg, along with United Arab Emirates (UAE) astronaut Sultan Alneyadi and Roscosmos cosmonaut Andrey Fedyaev.

Remembering the Gutsy and Hilarious Apollo Astronaut Jim McDivitt

An image of Jim McDivitt on Apollo 9, March 7, 1969, where McDivitt is conducting the world’s first docking of two crewed spacecraft with internal transfer – a technique that would become critical in the later missions to the moon. The image is from underexposed film and recovered by Andy Saunders, who used it for the cover shot of the new book “Apollo Remastered.” Credit: NASA / JSC / ASU / Andy Saunders.

Former NASA astronaut Jim McDivitt, who commanded the important Gemini IV and Apollo 9 missions – both crucial for NASA’s ability to reach the Moon — has died at age 93. His family said he passed away peacefully in his sleep on October 13, 2022.

NASA Chooses a Supplier to Build its Moonwalking Spacesuits

NASA announced they have chosen Axiom Space to build the spacesuits for the next astronauts to walk on the Moon. The spacesuits will be used on the Artemis III mission, which is planned to land the first woman and the first person of color on the lunar surface.

Axiom Space says the new spacesuits will provide astronauts with advanced capabilities for space exploration while providing NASA commercially developed human systems needed to access, live, and work in microgravity as well as on and around the Moon.

Using Virtual/Augmented Reality and Holoportation to Help Improve Mental Health for Future Mars Astronauts

We recently explored how the Apple TV+ series, For All Mankind, gives us a harsh reality check about the harshness of human space exploration. In the show, astronauts struggle, some go crazy, and a lot of them die in the pursuit of planting our flag just a little farther from home. We discussed how while For All Mankind is both science fiction and takes place in an alternate universe, our future Artemis and Mars astronauts will very likely endure the same struggles and hardships as the show’s beloved characters.

When Artemis astronauts finally land on the Moon, they’ll be there anywhere from a few days to a few months. While the Moon is only a few days travel time from Earth, Artemis astronauts may still get a little cranky being stuck in their habitat and unable to go outside without a spacesuit.

We Still Have no Idea if it's Safe to be Pregnant in Space

Can humans reproduce in space? The short answer is that we don’t know. The long answer is maybe, but there are significant barriers to overcome to make zero-gravity pregnancy safe, and research into the subject is only just beginning.

Socks, The Final Frontier

What is the greatest challenge facing humans as we prepare for the first crewed missions to Mars? Solar and cosmic radiation? Atrophying bone and muscle? Growing food? How about laundry? It’s strange but true, right now we don’t have a way to clean laundry in space.

Astronauts Going to Mars Will Receive Many Lifetimes Worth of Radiation

In a recent study published in Space Physics, an international team of researchers discuss an in-depth study examining the long-term physiological effects of solar radiation on astronauts with emphasis on future astronauts traveling to Mars, to include steps we can take to help mitigate the risk of such solar radiation exposure. The researchers hailed from the United Arab Emirates, New Zealand, India, United States, Italy, Greece, and Germany, and their study helps us better understand the in-depth, long-term health impacts of astronauts during long-term space missions, specifically to Mars and beyond.
