A NASA spacecraft sent out to collect rocks from an asteroid seems to have nabbed a lot of material, but there's now an unexpected problem — a flap isn't closing because some rocks are stuck.
NASA has collected and is returning its first sample from an asteroid. The rocks and dust could help us understand potentially dangerous space rocks and the history of the solar system.
Astronauts have been able to cast ballots from above since the Texas legislature gave its blessing in 1997. "It's critical to participate in our democracy," NASA astronaut Kate Rubins said.
The sun can affect people's electronics, the power grid and communications and navigation systems. But scientists predict that for the next decade or so, the sun's activity will not be too disruptive.
Scientists have found a gas associated with living organisms in a region of Venus' atmosphere. They can't figure out how it got there if it didn't come from life.
Scientists and engineers in California are building a unique 3.2 billion pixel camera for a telescope under construction in Chile. The camera has taken its first test pictures — of broccoli.
An experiment involving some "mighty mice" on the International Space Station could someday help astronauts maintain muscle and bone strength on interplanetary journeys.
None of us is perfect, and sometimes the Hubble Space Telescope just flat-out points to the wrong spot in the sky. This has been happening more than ever in the last couple of years.
An experimental drug let mice spend a month in the International Space Station's near-zero gravity without losing mass. It could help people spend years in space without major health consequences.
