Scientists suspect iron meteorites might be able to resist erosion on Mars, which may explain why some appear perched on flat ground rather than embedded in craters. In other cases, a crater may have weathered away long ago, leaving only the rock behind.

The ESCAPADE mission, which launched to space on a Blue Origin rocket on Thursday, breaks the mold of how planetary science missions typically come together.

For the first time in more than five years, humanity has launched a mission to Mars — but it won't be arriving at the Red Planet anytime soon. NASA's twin ESCAPADE probes launched Thursday (Nov. 13) on the second-ever flight of Blue Origin's powerful New Glenn rocket.

A new analysis of data from NASA's Mars Reconnaissance Orbiter reveals that the majority of the Red Planet's dark "slope streaks" did not form as most researchers previously assumed.

NASA's giant Mars Antenna failure hinders spacecraft communication and asteroid studies amid the federal government shutdown.
