Study: Trip to Mars Could Weaken Astronaut’s Immune System

January 25, 2019

Some of the biggest challenges NASA faces, if it is to meet its goal of sending humans to Mars, is making sure its astronauts are kept healthy and safe from harm. Unlike current space flights, a round-trip mission to Mars could take up to 3 years. Cosmic and solar radiation and a weakening of muscles and bones […]

Four members of the joint STS-135/Expedition 28 crews are able to spend part of their last shared time onboard the International Space Station performing floating exercises that can't be done in Earth's gravity. Inside the Harmony Node 2 module, are NASA astronauts Mike Fossum (top), Expedition 28 flight engineer, and Doug Hurley, STS-135 pilot; and Ron Garan, Expedition 28 flight engineer. The crew member at bottom is partially obscured and is unidentified. (NASA)

Weightlessness Can Cause Body Temperature to Rise

February 14, 2018

Watching astronauts float in the weightlessness of space may look like a lot of fun, but scientists have found that such an environment can also have negative physical and psychological effects on humans. Scientists from Germany’s Charité – Universitätsmedizin Berlin say they have found another health aspect of weightlessness – it can produce a higher body temperature. […]

This time-lapse video, assembled from a set of Hubble Space Telescope photos, reveals two asteroids orbiting each other that have comet-like features. The asteroid pair, called 2006 VW139/288P, was observed in September 2016, just before the asteroid made its closest approach to the Sun. (NASA, ESA, and J. DePasquale and Z. Levay (STScI))

But scientists seem […]
