Just got this message from my nephew at Oxford Uni... "There is a (admittedly slight) chance that a recently discovered comet, C/2013 A1 (Siding Spring), might be on a collision course with Mars in October 2014. Latest observations certainly include an impact possibility within the range of error. If it hits, estimates suggest a 500km wide, 2km deep crater arising from a ~20 Petaton event. That's something like 4 million times the (estimated) explosive power of the current global nuclear arsenal. Would be interesting to watch and see if any of the rovers on the surface manage to survive such an impact (I would imagine only possibly Curiosity but keeping lines of communication open with it might prove difficult). Might make for (eventually, but not in our lifetimes) some interesting future Martian meteorites." http://www.universetoday.com/100298/is-a-comet-on-a-collision-course-with-mars/ Graham Received on Wed 27 Feb 2013 07:38:24 AM PST |
