The tiny helicopter took off and hovered briefly — the first such flight on another planet. The Perseverance rover kept tabs on the mission from a viewing point about 60 yards away.

NASA is counting down to what should be the final major test of the massive rocket it is building to put the first woman and the next man on the moon.

Following a 300 million-mile voyage through space and a dangerous drop to the surface, Perseverance will be put through its paces before getting to a search for ancient Martian life.

After the InSight lander had trouble drilling a sophisticated thermometer into the Martian surface, a Plan B also didn't work, and the instrument ended up backing itself out of the ground.

The European Space Agency's new images show a 51-mile-wide ice-filled depression in the surface of Mars caused by the impact of a meteorite or other celestial body.

There's a new probe on Mars. After Monday's tricky landing, NASA's InSight spacecraft is to deploy a sensitive seismometer and temperature probe to let scientists explore the planet's interior.

With the sun entirely blocked out by dust, the solar-powered rover has presumably fallen asleep to wait out the storm. NASA scientists say they are "very concerned," but that they hope for the best.

Scientists can't say whether there is, or ever was, life on the Red Planet. But two Martian rock samples contained organic molecules — which contain carbon, the chemical element central to life.

It captured images that show some of the key regions NASA's robot has explored since 2012.

The streaks on the Red Planet's surface appear to be caused by salty water, but how much water there is — and where it comes from — remains a mystery.
