As winds whirled and converged to the west of Endeavour Crater, Opportunity's power dropped dramatically in October, but the Mars Exploration Rover (MER) pressed on. By month's end, the robot field geologist had completed her assignments – including capturing the first close-in shot of a comet from the surface of the Red Planet – and was roving onward through the darkness, driving the mission into the 130th month of what started out more than 10-and-a-half years ago to be a 3-month tour.

Mars Orbiter Mission shifts orbit to take cover from Siding Spring

Srinivas Laxman • October 09, 2014

With only 10 days remaining until the arrival of Comet Siding Spring at Mars, ISRO has shielded the Mars Orbiter Mission (MOM) from the comet. On Tuesday MOM’s orbit was altered so as to move it behind the Red Planet when the comet arrives. MOM will carry out observations of the comet and its Mars Colour Camera will click images of it.
