Engineers have successfully tested a spare reaction wheel on Mars Odyssey in their effort to bring the spacecraft back into full operation.
After more than 11 years of non-operational storage, the spare reaction wheel passed preliminary tests on Wednesday, June 12, spinning at up to 5,000 rotations per minute forward and backward. Odyssey engineers plan to substitute it for a reaction wheel they have assessed as no longer reliable. That wheel stuck for a few minutes last week, causing Odyssey to put itself into safe mode on June 8, Universal Time (June 7, Pacific Time).
Mars Odyssey put itself into safe mode on Friday when it detected problems with one of the three reaction wheels used to orient the spacecraft.

If this space probe goes down, it will make it more difficult to rely data back from Opportunity, now on the Martian surface, and Curiosity, due to land in two months.
Winter on Mars has finally ended, and Opportunity is on the move again.

Though this Science article outlines well the present “consensus” for Mars’s past climate, it also tries to make it sound like the planetary science community had once believed that Mars was once ocean-covered like the Earth and now has abandoned that consensus. To this I say bunk. Though many respected planetary scientists have looked for and found evidence for a past ocean on Mars, this possibility has always been controversial. From my readings most planetary scientists have always believed that Mars has generally been dry, interspersed with short periods when there is flowing liquid water on its surface. Even the advocates of the Martian ocean never proposed an Earthlike ocean, but a somewhat shallow and short-lived phenomenon.
