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.

Comet Siding Spring Mars encounter: How to determine the orbit of a comet?

ESA Mars Express Team • March 12, 2014 • 2

In the quest to track Comet Siding Spring, the Mars Express team tells us how computing the orbit of a comet isn't as straightforward as science fiction would have us believe.

Hypervelocity Cratering and Riding Out the Risk

ESA Mars Express Team • March 06, 2014

Today's update from the Mars Express team contains the realisation that, for some of the risks associated with October's Siding Spring flyby, there may not be much the team can do.

Space is really, really big – except sometimes it isn’t

ESA Mars Express Team • March 04, 2014

Here's the next installment in the continuing story of how the Mars Express team is preparing for Comet Siding Spring flyby, 19 October 2014. This week: introducing the spacecraft's subsystems and structure – and wondering how we can absorb impacts.

Comet Siding Spring Mars encounter: Why orienting Mars Express is the heart of the challenge

ESA Mars Express Team • February 28, 2014

Today's post continues where we started last week with an update from the Mars Express Flight Control Team at ESOC on their preparations for the 19 October Comet Siding Springs flyby. Today: defining the challenge!

Mars Express team readies for Siding Spring

On Sunday, 19 October 2014, at around 18:30 UTC, comet C/2013 A1 – known widely as 'Siding Spring' after the Australian observatory where it was discovered in January 2013 – will make a close fly-by of Mars.

A new comet observing campaign for C/2013 A1 (Siding Spring)

Karl Battams • January 27, 2014 • 1

You thought you were rid of us...but we're back! Following the spectacular and, quite frankly unprecedented, success of the Comet ISON Observing Campaign, we are launching a similar venture for another unique cometary encounter that's happening this year. In October 2014, comet C/2013 A1 (Siding Spring) will pass extremely close to Mars.

Will comet Siding Spring make a meteor shower on Mars?

Emily Lakdawalla • March 05, 2013 • 6

JPL's Solar System Dynamics group shows that there is still a possibility that C/2013 A1 (Siding Spring) could hit Mars. But the uncertainty in its position at that time is large -- the closest approach could happen an hour earlier, or an hour later -- so we're a long way from knowing yet whether it will or (more likely) won't impact.

Comet to whiz past Mars in October 2014

A recently discovered comet, C/2013 A1 (Siding Spring), is going to be passing very close to Mars on October 19, 2014. Does it pose a risk to spacecraft?

Lovely album of photos from WISE
