Some of Mars' most important secrets are hiding beneath the surface.

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

ESA Mars Express Team • September 17, 2014 • 2

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.

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

Tony Farnham • September 09, 2014 • 5

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?

Comet Flyby Missions for Mars Rovers

Mark Lemmon • August 21, 2014 • 2

On October 19, the Mars rovers — like their orbiting cousins — will become comet flyby missions. Comet C/2013 A1 (Siding Spring) will pass within 140,000 km of Mars.

Mars orbiters plan for their October encounter with comet Siding Spring

Emily Lakdawalla • August 13, 2014 • 2

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.

Comet Siding Spring: Risk Assessment

Karl Battams • August 07, 2014 • 6

On October 19, 2014, Comet Siding Spring is going to have an extremely close encounter with the planet Mars. The bottom line: it seems most likely that our Martian spacecraft will be absolutely fine.

Opposition time for Mars, and several months of dancing with the stars

ESA Mars Express Team • April 08, 2014 • 1

The Mars Express team showcases some of the best viewing opportunities of Mars in 2014, including how to spot Comet Siding Spring when it flies past Mars this October.

Comet Siding Spring Mars encounter: Cosmic bully spotted by ESA and NASA

ESA Mars Express Team • March 31, 2014

Hubble has taken some great new images of our 'friend,' Comet Siding Spring, due to pass by Mars at less than 136,000 km on October 19 – less than half the distance between Earth and our moon.

Comet Siding Spring Mars encounter: Ya gotta have a little ‘tude

ESA Mars Express Team • March 24, 2014

In the latest update on how the Mars Express flight control team is planning to deal with Comet Siding Spring is all about attitude -- and hiding behind the biggest guy in the fight.
