The abstract of the open access 2014 paper Meteor hurricane at Mars on 2014 October 19 from comet C/2013 A1 says:
omet C/2013 A1 will make a very close approach with the planet Mars on 2014 October 19. For this event, we compute the density of cometary dust particles around the Mars Express spacecraft, in order to assess the real risk for space probes. We also estimate the zenithal hourly rate (ZHR) and discuss observational opportunities for the resulting Martian meteor shower. We find, for a surface of 2.7 m2, that the Mars Express spacecraft will experience approximately 10 impacts from particles larger than 100 μm in size. The fluence per square metre is found to be 3.5 during the encounter. The equivalent ZHR is computed to be ZHR ≃ 4.75 × 109 h−1, making this event the strongest meteor storm ever predicted. We call this event a ‘meteor hurricane’, which we define to be a meteor shower with ZHR exceeding 106 h−1. The event will last approximately 5 h in total, and peak around 20:00 UT (Earth UT time). We call for observations of this unique event by all possible means, but also warn operators of Mars-orbiting spacecraft against the risks of impacts from comet particles larger than 100 μm, with impacts speeds of 57.42 km s−1.
The paper warns operators of Mars-orbiting spacecraft of a "meteor hurricane" and estimates the real possibility of Mars Express getting hit by a 100 μm particle at 57 km/s.
It also suggests that folks watch for this event "by all possible means".
- Did Mars Express get hit by a "Meteor hurricane"? (2014 October 19, comet C/2013 A1) Were any impacts detected at all during this timeframe?
- Was the observed at all "by all possible means"? For example did any rover try to look for meteors at dusk while the sky darkened but they were still warm enough to operate? Did any orbiting spacecraft look down on the night side for fireballs?
