The Polaris Dawn mission, funded by billionaire Jared Isaacman and Elon Musk’s SpaceX, may hint at the future of space travel.
NASA’s decision to send Starliner’s crew home on a SpaceX capsule will have implications for Boeing, the agency itself and the astronauts still on the space station.
Lunar volcanism was thought to have stopped two billion years ago.
These small galaxies are either crammed with stars or they host gigantic black holes. The data astronomers have collected continues to puzzle them.
Traveling to space is riskier than many extreme sports − an increase in private missions could mean more civilians taking that risk.
Meteorites contain a wealth of information about the origins of our solar system, helping us to understand their, and even Earth’s, origin and evolution.
Most planets that have the potential to host life have one side always facing their sun.
While space is mostly empty, it does have some matter and particles spread throughout it.
For years, researchers have wondered what energy source allows the solar wind − a projection of charged particles from the Sun − to rush by at hundreds of miles a second.
Nasa’s decision to prioritise the safety of the astronauts, and to work with another commercial partner in finding a solution, is a triumph of wisdom and caution.
The SpaceX-backed mission has no professional astronauts aboard.
Boeing Starliner took the astronauts to the International Space Station – but NASA doesn’t think it’s safe for the return trip. What happens next?
The Polaris Dawn mission will test communications, perform research and conduct a spacewalk with SpaceX extravehicular spacesuits.
The new study seems to confirm that molten magma covered the Moon’s surface shortly after its formation.
The space missions of the future will need to coordinate multiple satellites and spacecraft − and figure out how to refuel, repair and even replace them in orbit.
If a star gets too close to a black hole, it gets shredded and produces a complex ball of light. These videos are the first time this dramatic event has been simulated in detail.
The manoeuvres will set up an encounter with Jupiter in 2031.
Space may be considered the final frontier, but the US was once a frontier, too. How can space industry leaders avoid repeating practices that led to colonialism in the 18th century and beyond?
Butch Wilmore and Suni Williams were supposed to stay around eight days on the space station.
