HELPFUL TIPS: How to Clean Your Space Underwear

by
NASA Space Underwear

We can probably all agree that sharing your unwashed underwear with another person isn’t ideal. However, for astronauts onboard the International Space Station (ISS), performing a spacewalk requires that they share not only the spacesuits, but also a next-to-the-skin piece of clothing that’s worn underneath the spacesuit and resembles long underwear, known as the Liquid Cooling and Ventilation Garment (LCVG). Access to a freshly laundered LCVG isn’t an option on the ISS, but technicians with the European Space Agency (ESA) are taking steps to improve the antimicrobial properties in LCVG materials to keep these shared garments clean and fresh for … Read more

MARS: NASA Extracts Breathable Oxygen From Thin Martian Air

by
Mars

NASA has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen, the U.S. space agency said on Wednesday. The unprecedented extraction of oxygen, literally out of thin air on Mars, was achieved Tuesday by an experimental device aboard Perseverance, a six-wheeled science rover that landed on the Red Planet Feb. 18 after a seven-month journey from Earth. In its first activation, the toaster-sized instrument dubbed MOXIE, short for Mars Oxygen In-Situ Resource Utilization Experiment, produced about 5 grams of oxygen, equivalent to roughly 10 minutes’ worth of breathing … Read more

SCIENCE: Spaceflight Shrinks Your Heart

What do extreme long-distance swimming and spaceflight have in common? They can both shrink the heart, according to a new study. Both activities reduce the pressure of gravity on the heart, making it so that it doesn’t have to work as hard to pump blood upwards through the body. The heart is a muscle, and just like any other muscle in the body, if it’s not used as much as it used to be, it will shrink. To understand what effect weightlessness has on the heart, a group of researchers analyzed health data from retired astronaut Scott Kelly’s year aboard … Read more

NASA Plans to Land First Person of Color & First Woman on the Moon by 2024

by
Artemis Program - Amazon

NASA will land the first person of color in addition to the first woman on the moon with the Artemis program, NASA’s Acting Administrator Steve Jurczyk revealed today (April 9). Today, President Joe Biden’s administration submitted a budget proposal outlining its priorities for discretionary spending for the fiscal year 2022 to Congress. The proposed budget includes a funding increase that will support Mars sample return, research, climate science and more at NASA. Jurczyk responded to the news in a NASA statement and additionally revealed that the agency will be landing the first person of color on the moon with the … Read more

They’re Baaack – SpaceX Astronauts Splash Down (Video)

by
SpaceX Splashdown

Update 2:50 pm EDT: Everything went as planned, with SpaceX and NASA reporting a successful splashdown. The astronauts radioed in from inside the capsule that they were feeling good. A recovery team has begun the process of extracting the crew from the capsule, while the astronauts run some final checks. The SpaceX Crew Dragon “Endeavour” is on its way back to Earth with astronauts Bob Behnken and Doug Hurley. If all goes well, the splashdown will mark the completion of a successful first flight of the commercial crew era. The vehicle is scheduled to splash down in the Gulf of … Read more

SCIENCE: Space Shrinks Your Brain

Going to space does more than change the way you look at the world — it also changes your brain. In a new small study, published today (Oct. 24) as a Letter to the Editor in The New England Journal of Medicine, a team of researchers from Germany, Belgium and Russia detailed changes in the brains of 10 cosmonauts before and after long-term missions to space, finding “extensive” changes to the brain’s white and gray matter. What these changes mean for the cosmonauts is still an open question. “However, whether or not the extensive alterations shown in the gray and … Read more

SPACE: Going to Mars? You Might Glow in the Dark When You Return

There are plenty of challenges to putting people on Mars, whether you look at the rocket, the astronaut or the planet itself. New data from one of the many spacecraft at work around Mars confirm just how dangerous a round-trip human journey would be by measuring the amount of radiation an astronaut would experience. Cosmic radiation is made up of incredibly tiny particles moving incredibly fast, nearly at the speed of light — the sort of phenomenon a human body isn’t very well equipped to withstand. That radiation travels across all of space, but Earth’s atmosphere buffers us from the … Read more

For Writers: Astronaut Blindness

Today’s writer topic comes from QSFer J. Scott Coatsworth: I saw this article the other day and it fascinated me: https://www.washingtonpost.com/national/health-science/the-mysterious-syndrome-impairing-astronauts-eyesight/2016/07/09/f20fb9a6-41f1-11e6-88d0-6adee48be8bc_story.html It seems like it could be addressed eventually with rotating space stations and centrifugal force, or maybe artificial gravity? I wonder how long is “safe” to be in a weightless environment? And what other things might space do to the human body? I smell plot bunnies! Join the chat
