Last year, Spirit became stuck in loose sand. This prevented the rover from driving to a sun-facing slope for the winter

NASA mission controllers have not heard from Mars rover Spirit since March 22 as the rover faces its toughest challenge yet – trying to survive the harsh Martian winter.

On July 26, mission managers began using a paging technique …

Mariner 9 image of the north polar cap of Mars. The image was taken on 12 October 1972, about one-half Martian month after summer solstice, at which time the cap had reached its minimal extent. The cap is about 1000 km across. The interior dark markings are frost-free sun-facing slopes. A smooth layered sedimentary deposit underlies the cap. The image

Two images of the Phoenix Mars lander taken from Martian orbit in 2008 and 2010. The 2008 lander image shows two relatively blue spots on either side corresponding to the spacecraft’s clean circular solar panels. In the 2010 image scientists see a dark shadow that could be the lander body and eastern solar panel, but no shadow from the western

The purpose of the Mars500 study is to gather data, knowledge and experience to help prepare for a real mission to Mars. Obviously there will be no effect of weightlessness, but the study will help to determine key psychological and physiological effects on people in such an enclosed environment for such an extended 520-day period of time.

The experiment is …

A crew of six, including two Europeans, will soon begin a simulated mission to Mars in a mockup that includes an interplanetary spaceship, Mars lander and martian landscape. The Mars500 experiment, as long as a real journey to Mars, is a test of human endurance.

Their mission is to mimic a full mission to Mars and back as accurately as …

Images from the recent flyby of Phobos, on 7 March 2010, are released today. The images show Mars’ rocky moon in exquisite detail, with a resolution of just 4.4 metres per pixel. They show the proposed landing sites for the forthcoming Phobos-Grunt mission.

ESA’s Mars Express spacecraft orbits the Red Planet in a highly elliptical, polar orbit that brings it …

This image of Phobos’s surface was obtained by the Super Resolution Channel (or SRC, a part of the High Resolution Stereo Camera experiment) on board ESA’s Mars Express on 3 August 2008 (orbit 5889). The distance from the moon’s centre was 656 km, and the image resolution is 6 m/pixel. The original image has been corrected for mirror distortion. Credits:

Spirit’s view of its own predicament. The rover is now parked for the winter with its solar panels tilted 9 degrees away from the sun.

Mars rover Spirit has tenaciously swept, scraped, and squeezed secrets from the forbidding surface of Mars for 6 years. Now at an impasse, up to its belly in sand, it has struggled to tilt its …

Jan. 26, 2010: After six years of unprecedented exploration of the Red Planet, NASA’s Mars Exploration Rover Spirit no longer will be a fully mobile robot. NASA has designated the once-roving scientific explorer a stationary science platform after efforts during the past several months to free it from a sand trap have been unsuccessful.

The venerable robot’s primary task in …

It rises in the east at sunset, pumpkin-orange and brighter than a first magnitude star. You stare at it, unblinking. Unblinking, it stares right back.

It is Mars.

This week Earth and Mars are having a close encounter. On Jan. 27th, the Red Planet will be only 99 million kilometers away and look bigger through a telescope than at any …
