Highlights from a Sept. 28, 2015, briefing with NASA officials discussing the strongest evidence yet that liquid water flows intermittently on present-day Mars.

All landings on Mars are difficult, but NASA's Perseverance rover is attempting to touch down in the most challenging terrain on Mars ever targeted.

What does it take to get a spacecraft to Mars? This 60-second video covers a few key things to remember when planning a trip to the Red Planet.

The Nasa rover called ‘Curiosity’ has finally arrived at Gale Crater on planet Mars after a 154 million miles journey, hurtling towards the Mars at over 13,000 mph. The main aim of Curiosity is to see whether the environment of Mars once held the ingredients of life and so Curiosity will drill into

2015 marks 50 years of successful NASA missions to Mars starting with Mariner 4 in 1965. Since then, a total of 15 robotic missions led by various NASA centers have laid the groundwork for future human missions to the Red Planet. The journey to Mars continues with additional robotic missions planned...

NASA's Mars Exploration Rover Mission (MER) is an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the sending of the two rovers—MER-A Spirit and MER-B Opportunity—to explore the Martian surface and geology.

Atlas V roars off the launch pad sending NASA's next Mars rover toward the Red Planet. The launch date was November 26, 2011 and the landing in Mars is scheduled for August 6, 2012.

Another giant leap towards a mission to Mars: expendable structures could be the next extraterrestrial breakthrough, as they weight less to launch and are more compact on the rocket. On arrival, they can be inflated to provide safe and sustainable living quarters, work spaces and laboratories for pe...

Landing the Curiosity rover on Mars is the most difficult and nail-biting part of the whole mission. See just how hard it is to land on Mars in this 60-second video.

A photo taken by NASA’s Mars Reconnaissance Orbiter appears to show spiders walking across the surface of Mars, but, in this case, things do not always look as they appear.
