Mars Orbiter Mission activates all science instruments as NASA, ISRO form joint Mars working group

Posted by Srinivas Laxman on 2014/10/01 11:19 CDT

Mars Orbiter Mission (MOM) began its science activities fully on Wednesday with all five science instruments being activated. And on Tuesday, an ISRO-NASA Mars working group was formed which will "seek to identify and implement scientific and technological goals that NASA and ISRO have in common regarding Mars exploration."

Curiosity update, sols 748-763: Driving and Drilling at Pahrump Hills

Posted by Emily Lakdawalla on 2014/09/29 05:57 CDT | 6 comments

The biggest news on Curiosity of late is that the rover has drilled her fourth full drill hole on Mars! Drilling happened at a site called "Confidence Hills" on sol 759. But before she did that, she took a long series of amazing photos of rock formations at Jubilee Pass, Panamint Butte, and Upheaval Dome.

Mars Orbiter Mission delivers on promise of global views of Mars

Posted by Emily Lakdawalla on 2014/09/29 11:15 CDT | 16 comments

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.

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

Posted by ESA Mars Express Team on 2014/09/17 10:44 CDT | 2 comments

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.

Curiosity update, sols 727-747: Beginning the "Mission to Mount Sharp"

Posted by Emily Lakdawalla on 2014/09/12 07:08 CDT | 3 comments

A lot has happened behind the scenes on the Curiosity mission in the last few weeks. The mission received a pretty negative review from a panel convened to assess the relative quality of seven different proposed extended planetary science missions. Then, just a week later, the mission announced big news: they have arrived at Mount Sharp.

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

Posted by Tony Farnham on 2014/09/09 09:02 CDT | 5 comments

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?

Mars Exploration Rovers Update: Opportunity Suffers Unwanted Computer Reboots, Hunkers Down for Reformat
Sols 3740 - 3769

Curiosity update, sols 697-726: Mars thwarts driving and drilling

Posted by Emily Lakdawalla on 2014/08/22 04:24 CDT | 2 comments

The Mars gremlins really had it in for Curiosity this month. A computer glitch and slippery sand conspired to delay the rover's progress toward Mount Sharp. And shifting rocks proved unsafe for drilling. The rover will continue driving toward Mount Sharp, departing Bonanza King without drilling, skirting Hidden Valley along a plateau to its north.

Mars orbiters plan for their October encounter with comet Siding Spring

Posted by Emily Lakdawalla on 2014/08/13 06:00 CDT | 2 comments

Now that we have reasonable confidence that our Mars orbiters will be safe from the close passage of comet Siding Spring, we are free to be excited about the opportunity that the encounter represents. At a community workshop on August 11, representatives from Mars missions shared their plans for great comet science.
