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.

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

Posted by Emily Lakdawalla on 2014/09/15 04:53 CDT | 6 comments

This morning, the European Space Agency announced the selection of a landing site for little Philae on the head of comet Churyumov-Gerasimenko. Although a primary site has been selected, landing Philae successfully is going to be tough, and the mission is now working to manage people's expectations.

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?

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.
