Small chance Comet C/2013 A1 Siding Spring will impact Mars

Post by Tom » March 2nd, 2013, 11:51 am

Only a 1 in 10,000 chance of it actually hitting the Red Planet, but with it's nucleus at over 30 miles in diameter, it would be quite a spectacle. http://www.skyandtelescope.com/news/hom ... 06441.html

We now know that there is little chance for impact. Instead, Siding Spring will pass to within 139,500 kilometers of Mars. It will come closest around 1:27pm CDT on Sunday the 19th. Sadly, professional observatories in the Northern Hemisphere are all but "shut out" of observations of the close pass by Mars.

That isn't stopping NASA's fleet from trying its best to accumulate massive amounts of data on the object. This month the Hubble Space Telescope, Spitzer, Kepler, Chandra, the Curiosity and Opportunity rovers, MAVEN, Odyssey and the Mars Reconnaissance Orbiter will set their instruments on Siding Spring. Also, I believe NASA has at least one instrument on board Mars Express.

Siding Spring originated in the Oort Cloud.

The close pass will occur in just a few minutes. There is nothing on the NASA-TV schedule which suggests live coverage.

These are the instruments, crafts and locations which now should be monitoring the Mars-Siding Spring meeting this week...
The Chandra X-Ray Observatory: http://chandra.harvard.edu/
The Hubble Space Telescope: http://hubblesite.org/
The Infrared Telescope Facility: http://irtfweb.ifa.hawaii.edu/
The Kepler Spacecraft: http://keplerscience.arc.nasa.gov/K2/index.shtml
The Mars Exploration Rovers: http://mars.nasa.gov/mer/home/index.html
Mars Express: http://www.esa.int/Our_Activities/Space ... rs_Express
Mars Odyssey: http://www.nasa.gov/mission_pages/odyssey/index.html
Mars Orbiter Mission: http://isro.gov.in/mars/home.aspx
The Mars Reconnaissance Orbiter: http://www.nasa.gov/mission_pages/MRO/main/index.html
MAVEN: http://lasp.colorado.edu/home/maven/
The Spitzer Space Telescope: http://www.spitzer.caltech.edu/

Please keep in mind that the Mars-located craft and instruments might be protecting themselves from Siding Spring's accompanying dust.

This is the closest pass of a Solar System planet by a comet in recorded human history. Also try this page for information...
