Studies of recent Martian climate change are on the rise with new data from Mars Reconnaissance Orbiter. Much as scientists study Earth's ice ages through layered deposits, the science team is seeking clues to Mars' past by studying ice-rich layers at the Martian poles. The mineral gypsum and clay minerals found at the poles will be important, as they are indicators of wet conditions on Mars in the past. Radar penetrations that reveal thickness and fine-scale layering will also help define climate variations and environmental conditions on Mars over time.

Full story from Johns Hopkins University

NASA's latest orbiter to visit Mars achieved another mark of success this week. The mineral-mapping instrument on Mars Reconnaissance Orbiter has successfully removed its lens cover and is ready to start observing the planet. This comes on the heels of a successful test of the orbiter's subsurface radar antenna. This period of powering on instruments and completing calibrations leads up to the orbiter's primary science phase, beginning in November 2006.

August 30, 2006

Nearly six months after it entered orbit, Mars Reconnaissance Orbiter has concluded its aerobraking phase. The spacecraft had been dipping in and out of the red planet's atmosphere to adjust its orbit. On August 30, 2006, during its 445th orbit, the spacecraft fired its intermediate thrusters to raise the low point of its orbit and stop dipping into the atmosphere.

March 10, 2006

Cheers of joy filled the mission control area at NASA's Jet Propulsion Laboratory today as its latest mission to Mars met a critical mission milestone: Mars orbit insertion. At 2:16 p.m. (PST), ground controllers were informed by the Deep Space Network that they had locked up on Mars Reconnaissance Orbiter's signal as the spacecraft reappeared above Mars. This communication was a tremendous relief to the mission team as they had to wait nearly half an hour for their spacecraft to emerge from behind the red planet and back into range so that radio signals could again be transmitted. A few minutes later, it was confirmed that the orbiter was captured into the intended initial orbit.

This diagram illustrates the Mars Reconnaissance Orbiter's journey from launch to Mars. The inner circle (blue) represents Earth in orbit around the Sun (center). The green and yellow line represents the spacecraft on its way to Mars. The outer (red) circle represents Mars in orbit around the Sun. Four major stages of the mission are labeled: launch, cruise, approach and Mars orbit insertion. Also labeled are the opportunities for trajectory correction maneuvers, or chances to tweak the orbiter's path. The third trajectory correction maneuver was deemed unnecessary due to the precision of the spacecraft's current path.
