Moon to Mars

New findings show the heart becomes more spherical when exposed to long periods of microgravity in space, with implications for an eventual manned mission to Mars.

A new study shows that basalts from the Moon’s mantle contain hydrogen from water indigenous to Earth.

A new study shows that the nutritious value of leafy vegetables grown in space could be increased with bright pulses of light.

Researchers have found that some tumors seem to be much less aggressive in the microgravity environment of space compared to their behavior on Earth. This work is the latest in a large body of evidence on how space exploration benefits those of us on Earth.

A new study will examine the effect of gravity and radiation on DNA damage and repair. This kind of research not only aims to make space safer for astronauts, but to improve health care for the Earth-bound as well.

Scientists have calculated the radiation risk of a trip to Mars. The finding use data provided by NASA's Curiosity rover, and highlight the risks that future human explorers might face.

NASA has extended the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission for an additional 28 days. LADEE will now make the closest orbit of the lunar surface yet, gathering valuable data from low altitudes in the Moon's thin atmosphere.

A new study shows that growing up in space can weaken a key part of the immune system in fruit flies.

A new study reports how spaceflight alters the activity of a fungal pathogen.
