Tiny fruit flies are helping NASA study how brain activity and sleep patterns change when organisms live in the microgravity of space.
An experiment on the International Space Station will build on the United States' legacy of using fruit flies to understand how life endures in space.

WASHINGTON — SpaceX has been awarded a $150.4 million contract to launch as many as 28 satellites for the Pentagon’s space agency, the Defense Department announced Dec. 31.
The contract is to launch a mix of small and medium spacecraft of different sizes that the Space Development Agency is acquiring from multiple vendors.

Chemists at Scripps Research have made a discovery that supports a surprising new view of how life originated on our planet.

NASA has shown what it will look like when its Perseverance rover touches down on Mars, a challenging sequence that the agency describes as "7 minutes of terror."
The Perseverance rover was launched in the summer and is scheduled to arrive on Mars in February.

There's something a little off about our theory of the universe. Almost everything fits, but there's a fly in the cosmic ointment, a particle of sand in the infinite sandwich. Some scientists think the culprit might be gravity-and that subtle ripples in the fabric of space-time could help us find the missing piece.

In the far north, the swelling Arctic Ocean inundated vast swaths of coastal tundra and steppe ecosystems. Though the ocean water was only a few degrees above freezing, it started to thaw the permafrost beneath it, exposing billions of tons of organic matter to microbial breakdown. The decomposing organic matter began producing CO2 and CH4, two of the most important greenhouse gases.
