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.

Mars Exploration Rovers Update: Opportunity Gets Extension, Returns Killer Panoramas, and Roves onto Mystery Rocks

A.J.S. Rayl • October 04, 2014

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.

Philae's landing day announced as Rosetta swings to comet's dark side

Emily Lakdawalla • September 26, 2014

ESA announced today that Philae will be landing on November 12, 2014. What time the landing occurs depends on which landing site they use.

Mars Orbiter Mission test firing successful; all ready for orbit insertion

Srinivas Laxman • September 22, 2014

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).

MAVEN orbit insertion timeline

Emily Lakdawalla • September 21, 2014

Today's the day that MAVEN enters orbit at Mars, bringing the number of Mars orbiters up to four. So far everything looks good. The orbit insertion burn should begin tonight at 18:50 PDT / 01:50 UTC. I'll be on stage with Mat Kaplan and Rich Zurek at Planetary Radio Live, keeping up to date with the latest news from the spacecraft; here is a timeline in PDT, UTC, CEST, and IST to help you follow along.

Comet Siding Spring Mars encounter: One Mars Express plan becomes two

ESA Mars Express Team • September 17, 2014

The Mars Express Flight Control Team at ESOC have been actively preparing for the flyby of comet C/2013 A1/Siding Spring on October 19. Initial estimates gave the possibility that Mars Express might be hit by 2 or 3 high-speed particles. Happily, additional observations by ground and space telescopes have shown the risk to be much lower – and perhaps even as low as zero. In today's blog post, the team explain how this (happy!) real-life, real-time development is affecting their preparations for fly-by.

A landing site for Philae, but it's not going to be easy

Emily Lakdawalla • September 15, 2014

This morning, the European Space Agency announced the selection of a landing site for little Philae on the head of comet Churyumov-Gerasimenko.

So Close and Yet So Far: Why isn't Siding Spring going to sandblast Mars?

Tony Farnham • September 09, 2014

Comet Siding Spring is going to make a very close approach to Mars in October. Any comet dust that reaches Mars has the potential to inflict significant damage on the spacecraft orbiting the planet. As it turns out, however, Mars and its orbiters are likely to see very few, if any, impacts. Why?
