ORLANDO, Fla., Dec. 24 (UPI) – NASA is testing a space radiation protection vest aboard the International Space Station that could protect astronauts from deadly solar flames on missions to the moon and Mars.
Solar storms with high doses of radiation are among the biggest threats to astronauts on deep space missions. These worst storms could make space sheets too ill to work with and eventually kill them.
The new vest is designed with flexible polyethylene shapes to suit men or women and to protect their most vulnerable organs.
“We’re trying to see if astronauts can wear it as long as possible, without experiencing pain or discomfort,” said Oren Milstein, co-founder and CEO of vest maker StemRad, which is based in Tampa and Tel Aviv, Israel.
“Several astronauts wear the vest, with eight hours as the longest time, while they are asleep,” Milstein said.
The Cygnus Northrop Grumman cargo capsule delivered a StemRad space vest, called the AstroRad, to the space station in November 2019. Since then, astronauts have tested the vest, although NASA has not usually determined who the astronaut is. involved in medical-related trials.
StemRad has helped develop an AstroRad vest based on the 360 Gamma shield vest that protects first responders who need to cover live radio scenes.
Milstein helped find the company in 2011 in part in response to stories of the deaths of firefighters following the 1986 Chernobyl nuclear disaster in Russia.
StemRad is developing the vest for Lockheed Martin, who is a contractor with responsibility for the Orion team capsule on NASA’s planned Artemis lunar missions.
Orion includes a space radiation protection room or closet that can be pulled over by astronauts in an emergency, but that would only be possible for short periods of time, Milstein said. Radiation storms in space can last for days or weeks.
The vest provides targeted protection for the pelvis – where much bone marrow can accept radiation – and other organs such as the lungs, breasts and ovaries, Milstein said.
“Trying to protect the whole body means putting a lot of pressure on it,” he said. “You can reasonably protect a fragment of your body, or a part of your body that happens to be the most sensitive part.”
The space vest is being rolled out at a cost of about $ 1 million each, Milstein said, but the Israeli Space Agency is providing it as part of its contribution to the Artemis international lunar mission effort.
The vest on the space station is now a smaller version designed for women, but Milstein said a male astronaut will wear it at some point.
NASA made a brief note about an experiment in mid-December saying astronauts are trying on the vest.
“The AstroRad effectively protects astronauts from space-carrying ionizing radiation, provides operational simplification, and allows the use of recycled material on board the vehicle,” according to a NASA update.
In the meantime, StemRad has also unveiled new radiation conditions for doctors and radiologists on Earth, which are opposed to increased radiation exposure due to medical scanning equipment and radiation treatment.
The medical suit, known as a StemRad MD, provides both ease of use and better protection due to a heavy leaded cloth with an exoskeleton frame that fits on the outside of the wearer’s feet, said Jean Bismuth, 53, an expert in viral surgery at Houston. Methodist Hospital in Texas. He has been wearing the suit since October.
“It surprised me when I first got it. I ran the halls. I can sit and work or I can stand,” Bismuth said. “You need to have a little sense of place because the frames are on the outside of your feet, but this is an improvement for ergonomics and safety.”

Guinness World Records announced on October 19, 2020, that NASA astronauts Christina Koch (R) and Jessica Meir, who made history with the first female spacecraft on October 18, 2019, are honored for this achievement by feature in the Guinness World Edition 2021 edition. The historic spacewalk took place at the ISS, where they were working on maintenance and refurbishment. Although this was Koch’s fourth spacewalk, it was Meir’s first.

NASA astronaut Scott Kelly is delighted to be aboard the ISS following the hatch launch of the Soyuz spacecraft March 28, 2015. Kelly traveled with Expedition 43 Russian cosmonauts Mikhail Kornienko and Gennady Padalka on the launched Soyuz TMA-16M the day before from Baikonur, Kazakhstan.

Kelly cared for two crops at the Veggie Plant Growth Facility during his year in space. Understanding the most effective ways to grow plants in microgravity is a key part of the future trip to Mars. Growing plants in space will provide crew members with fresh food to supplement their diet, as well as a positive effect on confidence and well-being. Image courtesy of NASA
