In one of the most dramatic, high-risk space flights to date, SpaceX launched a gargantuan Super Heavy-Starship rocket on an unpiloted test flight

One day after launching a Starship rocket on a dramatic test flight in Texas, SpaceX readied a Falcon Heavy rocket for launch Monday from Florida

The ambitious mission won't actually look for life, but it should find out if the presumed ocean provides a habitable environment.

In one of the most dramatic, high-risk space flights to date, SpaceX launched a gargantuan Super Heavy-Starship rocket on an unpiloted test flight Sunday and then used giant "mechazilla" mechanical arms on the pad gantry to pluck the descending first stage out of the sky in an unprecedented feat of engineering. The Starship upper stage, meanwhile, looped around the planet and re-entered the atmosphere over the Indian Ocean as planned, enduring temperatures nearing 3,000 degrees as it descended to a controlled, on-target splashdown. The spacecraft came through the hellish heat of re-entry in relatively good condition, protected by improved heat-shield tiles and beefed-up steering fins

Returning astronauts taken to “local medical facility” after initial checks aboard recovery ship

Three NASA astronauts who just wrapped up a 235-day mission to the International Space Station discussed their flight with reporters Friday, but

Researchers analyzed lunar soil brought back by China's Chang'e-6, the first spacecraft to return with a haul of rocks and dirt from the little-explored far side.

Marc and Sharon Hagle, both making their second space flight, were among the passengers for the NS-28 mission.
