It might kill us, but the perchlorate-rich liquid water of Mars could be our best opportunity yet of rooting out the possibility of microbial Martian life.
Scientists have their first evidence that trickles of liquid water play a role in sculpting mysterious dark streaks that appear during summertime months on Mars.
Once again the world is abuzz about water on Mars -- what's the fuss about this time?
Spacecraft landings and water evidence are just some of the cool things NASA Mars Reconnaissance Orbiter has spotted in its 10 years after launching to the Red Planet.
The Earth and Mars will be on opposite sides of the sun this month, meaning we'll lose contact with our beloved Mars rovers and orbiters.
NASA's Mars Reconnaissance Orbiter (MRO) has spotted its roving buddy Curiosity on the Martian landscape, but the rover seems to be missing its tell-tale tracks in the red planet's dirt.
After Curiosity dramatically touched down on Mars in 2012, it kicked up some dirt that still hasn't faded from view.
Like a coworker looking over her shoulder in the office, Curiosity has a Martian colleague checking up on her progress from high above.
