Early Mars may have had a warmer and denser atmosphere allowing for the presence of liquid water on the surface. However, climate model studies have not been able to reproduce these conditions even with a CO2 atmosphere of several bars. Recent 3D simulations of the early Mars climate show that mean surface temperatures only slightly below 273K could be reached locally.

Explosive Crater Twins on Mars

High-Resolution Stereo Camera nadir and colour channel data taken during orbit 11467 on 4 January 2013 by ESA's Mars Express have been combined to produce this colour view of two craters, both roughly 50 km in diameter. The data were acquired in the Thaumasia Planum region just south of Vallis Marineris at approximately 17°S / 296°E and have a ground resolution of approximately 25 m per pixel. The northern (right) crater is named Arima, while the southern (left) crater is unnamed. Both large craters sport central pit features.

Hardware from a spacecraft that the Soviet Union landed on Mars in 1971 might appear in images from NASA's Mars Reconnaissance Orbiter.

Explosive Crater Twins on Mars

Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA's Mars Express on 4 January. The 'twin' craters are in the Thaumasia Planum region, a large plateau that lies immediately to the south of Valles Marineris, the largest canyon in the Solar System.

Mars' Atmosphere Is Still Dynamic

Mars has lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate. Rover team members reported diverse findings today at the European Geosciences Union 2013 General Assembly, in Vienna.

Photos from NASA's Mars Reconnaissance Orbiter show how the parachute that helped NASA's Curiosity rover land on Mars last summer has subsequently changed its shape on the ground.

Opportunity Update: March 21-26, 2013

Opportunity Moves Into Place for Quiet Period of Operations - sols 3255-3260, Mar. 21, 2013-Mar. 26, 2013: This location, called 'Big Nickel,' is the last in-situ (contact) target before the rover departs from Cape York, once solar conjunction is concluded.

The discovery of box-like geologic structures on Mount Sharp centered in Curiosity's Gale crater landing site, is raising interest for rover exploration as potentially habitable for past life on Mars.

Restarting science operations after 3 weeks of computer problems, the Mars rover Curiosity will be using its robotic arm and the Goddard Sample Analysis at Mars (SAM) laboratory to process a triple-dose of drilled subsurface rock in a more intense search for organic carbon before April 4, when Mars will move behind the Sun blocking communications until May 1.

The positions of the planets next month will mean diminished communications between Earth and NASA's spacecraft at Mars.

NASA's Mars rover Curiosity is expected to resume science investigations in a few days, as engineers quickly diagnosed a software issue that prompted the rover to put itself into a precautionary standby status over the weekend.

Scientific confirmation that the NASA Mars rover Curiosity has found a location habitable to Martian microbial life 3 billion years ago is an historic milestone in planetary exploration.

ESA and Roscosmos set for Mars missions

ESA and the Russian federal space agency, Roscosmos, have signed a formal agreement to work in partnership on the ExoMars programme towards the launch of two missions in 2016 and 2018.

NASA's Mars rover Curiosity continues to move forward with assessment and recovery from a memory glitch that affected the rover's A-side computer. Curiosity has two computers that are redundant of one another. The rover is currently operating using the B-side computer, which is operating as expected.

Sols 3234-3240, Feb. 27, 2013-Mar. 05, 2013: Opportunity is exploring different locations around the inboard edge of 'Cape York' on the rim of Endeavour Crater.

An analysis of a rock sample collected by NASA's Curiosity rover shows ancient Mars could have supported living microbes.

The latest trajectory of comet 2013 A1 (Siding Spring) generated by the Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., indicates the comet will pass within 186,000 miles (300,000 kilometers) of Mars and there is a strong possibility that it might pass much closer.

Scientists with the $2.5 billion Mars rover Curiosity will reveal potentially historic discoveries about Mars next week in Washington D. C.

Survey on Sending Humans to Mars

Phillips & Company, a global communications firm, and Explore Mars, a non-profit corporation committed to advancing the cause for human exploration of Mars, today released findings and full analysis of a nationwide survey of U.S. citizens that focused on their opinions about the exploration of Mars.

The Mars rover Curiosity is this week in the midst of potentially historic discoveries as the full range of its capabilities are brought to bear for the first time on a gray powdered Martian subsurface rock sample.
