Mission Control will be packed with experts, specialists and flight directors around-the-clock as NASA takes on its most complicated mission in more than half a century.

NASA faces concerns over crew safety for future lunar landings as a new report reveals lack of rescue capability for stranded astronauts.

One of NASA’s spacecraft could reenter the atmosphere at approximately 7:45 P.M. EDT tonight. When the 600-kilogram Van Allen Probe A reenters Earth’s atmosphere, it will largely burn up, but there

The mission without a doubt proves that we could deflect a hazardous asteroid away from Earth — so long as we discover it in the nick of time.

This reentry is notable because it poses a higher risk to the public than the US government typically allows. The risk of harm coming to anyone on Earth is still low, approximately 1 in 4,200, but it exceeds the government standard of a 1 in 10,000 chance of an uncontrolled reentry causing a casualty.

When, during the International Space Station (ISS) mission, astronauts Sunita Williams and Butch Wilmore stretched from eight days to over nine months.

Images captured in late 2022 by the DART spacecraft — an experiment that tested asteroid-deflection technology — moments before it deliberately struck the asteroid moon Dimorp

In 1990, NASA carried out an unusual experiment that involved sending thousands of baby jellyfish into space. The goal was to study how living organisms develop in microgravity — and what that might mean for humans born beyond Earth. The experiment began ...
