Polaris Dawn is setting the stage for what will occur in low Earth orbit once NASA leaves the International Space Station, as the U.S. is planning to do.

The hatch of the Crew Dragon spacecraft opened for the first time into nothingness. Four people were exposed to the vacuum of space, and two peered through a ladder.

They're traveling farther than anyone else has in half a century.

The destruction of SpaceX’s mega-rocket on its second flight created one of the largest holes ever detected in the ionosphere, the ionized layer of the atmosphere.

Boeing has received approval from NASA to proceed with the undocking and autonomous return of the spacecraft.

The Polaris Dawn crew will travel farther from Earth than any humans have since the Apollo missions.

SpaceX lost a rocket that was completing its 23rd flight.

In a remote and rather unlikely scenario, Williams and Wilmore might have to cross the atmosphere in a SpaceX Crew Dragon without their spacesuits.

ULA CEO Tory Bruno accused SpaceX of passing off an incomplete Raptor 3 engine as finished one.

The astronauts on Boeing's Starliner, originally scheduled for a 10-day mission, have been on the International Space Station for two months now.

Preparations for Starship’s fifth flight are progressing.

NASA has stated behind closed doors that it hasn’t yet made a final decision.
