For instance, a NASA design study for an ambitious large space station envisioned 4 metric tons per square meter of shielding to drop radiation exposure to 2.5 mSv annually (± a factor of 2 uncertainty), less than the tens of millisieverts or more in some populated high natural background radiation areas on Earth, but the sheer mass for that ...
American astronaut Marsha Ivins demonstrates the effects of microgravity on her hair in space. The effects of spaceflight on the human body are complex and largely harmful over both short and long term. [1] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). [2]

People are now worried about their well-being after a doctor pointed out how “gaunt” Williams, 59, was starting to look. Health concerns started to grow after new photos of two NASA astronauts ...
A: The International Space Station is a really exciting place to live and work. The views are incredible. People ask me if I was bored while I was on the Space Station for six months and I can ...
March 8: A 0.7 kilograms (1.5 lb) piece of space junk that survived reentry has impacted a house in Naples, Florida. No people were harmed. No people were harmed. NASA later confirmed the object to be an inconel stanchion that was a part of a cargo pallet with old batteries jettisoned from the ISS in March 2021.
Humans reached outer space mediated in 1944 and have sustained mediated presence since 1958 , [a] as well as having reached space directly for the first time on 12 April 1961 (Yuri Gagarin) and continuously since the year 2000 with the crewed International Space Station (ISS), or since the later 1980s with some few interruptions through crewing ...
[1] [2] The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. [3] Research on the ISS improves knowledge about the effects of long-term space exposure on the human body.
