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.

It's now been two years since Dawn wrapped up its work at the second-largest asteroid. What else did we get from the Vesta encounter besides great photos? Recently, I asked Dawn's deputy project scientist, Carol Raymond, for help in summarizing a few of the big things Dawn taught us.

While the winds of Martian spring blew through Meridiani Planum in September, Opportunity reformatted its Flash memory then continued exploring Wdowiak Ridge on the western rim of Endeavour Crater. Even though the Flash-related issues soon returned, the robot field geologist hardly seemed to notice as it sent home two spectacular panoramas, presented the scientists with a rocky Martian mystery, and delivered yet another September to remember for the mission. And that's not all.

Ever since I first learned about the capabilities of Mars Orbiter Mission's small payload of science instruments, I have been anticipating one type of data in particular: global color views of Mars captured in a single 2000-pixel-square frame. Just days after entering orbit, Mars Orbiter Mission has delivered on that promise.

On Sepember 22 at 02:24 UTC, Earth received word that MAVEN had ended its orbit insertion burn on time, completing its journey to Mars. Today MAVEN has released some of its very first data, taken by the Imaging Ultraviolet Spectrograph just eight hours after arrival.

Here are a few links to what will hopefully be working video feeds watching India's first-ever attempt to place a spacecraft into orbit around another planet. Begin watching in just a few hours, at 6:15 IST / 00:45 UT / 17:45 PDT for an orbit insertion burn scheduled to begin at 07:30 IST / 04:00 UT / 19:00 PDT!

There was celebration in the Mars mission control room in Bangalore on Monday following the success of the crucial four-second test firing of the Mars Orbiter Mission’s (MOM) 440-Newton liquid apogee motor. MOM will now go ahead with the nominal plan for the Mars orbit insertion on September 24 at 07:30 IST (02:00 UT / September 23 19:00 PDT).
