Mars rovers

NASA's Perseverance Mars rover has captured photos of a big sunspot, which should rotate into view for those of us on Earth in the coming days.

NASA's Ingenuity Mars helicopter has taken to the skies yet again, covering 866 feet (264 meters) of ground on its 55th Red Planet flight.

The Curiosity Mars rover recently aced its toughest Red Planet climb yet: a sharp 23-degree slope covered slippery sand and wheel-size rocks.

NASA has test-fired rocket motors as part of the development of an ascent vehicle designed to launch samples off the surface of Mars.

Ancient mud cracks found by NASA's Curiosity rover suggest that Mars underwent a repeated cycle of wet and dry spells that could have supported the emergence of life.

NASA's Perseverance Mars rover captured a stunning video of the Ingenuity helicopter on Aug. 3, during the little chopper's 54th Red Planet flight.

Ingenuity is back in action and a 54th flight is already in the works, according to NASA. The helicopter is now resuming scouting duties for a big Mars rover mission seeking life.

A budget review from the Senate Appropriations Committee is suggesting NASA consider canceling Mars Sample Return if the agency can't rein in the mission's growing costs.
