Opportunity is continuing the circumnavigation of "Concepcion" crater. During this period Opportunity traversed around a ray of ejecta that is comprised of rock debris from the impact that formed the crater.

Spirit is in her winter position, still embedded in the area called "Troy" on the west side of Home Plate.

Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars.

New studies of ripples and dunes shaped by the winds on Mars testify to variability on that planet, identifying at least one place where ripples are actively migrating and another where the ripples have been stationary for 100,000 years or more.

Mars Express encountered Phobos last night, skimming past at just 67 km, the closest any manmade object has ever approached Mars' enigmatic moon. The data collected could help unlock the origin of not just Phobos but other 'second generation' moons.

NASA's newest Mars orbiter, completing its fourth year at the Red Planet next week, has just passed a data-volume milestone unimaginable a generation ago and still difficult to fathom: 100 terabits.

Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble.

ESA's Mars Express will skim the surface of Mars' largest moon Phobos on Wednesday evening. Passing by at an altitude of 67 km, precise radio tracking will allow researchers to peer inside the mysterious moon.

NASA's Mars Odyssey began a second campaign Monday to check on whether the Phoenix Mars Lander has revived itself after the northern Martian winter. The orbiter received no signal from the lander during the first 10 overflights of this campaign.

A dramatic 3D Mars view based on terrain modeling from NASA's Mars Reconnaissance Orbiter data shows "highs and lows" of Mojave Crater.

Spirit is parked for the winter in the embedded area called "Troy" on the west side of Home Plate. Efforts continue to prepare the rover for winter.

Opportunity Status for sol 2152-2157: Opportunity is positioned near the rim of the very young crater "Concepcion."

Today Mars Express began a series of flybys of Phobos, the largest moon of Mars. The campaign will reach its crescendo on 3 March, when the spacecraft will set a new record for the closest pass to Phobos, skimming the surface at just 50 km.

NASA's Mars Exploration Rover Spirit is now parked for the winter. The rover team is commanding Spirit this week to make additional preparations for the Mars southern hemisphere winter season.

Near the center of a Martian crater about the size of Connecticut, hundreds of exposed rock layers form a mound as tall as the Rockies and reveal a record of major environmental changes on Mars billions of years ago.
