Does the comet Siding Spring pose a threat to the Mars orbiter?
In 2013 it was thought possible that Comet Siding Spring would create a meteor shower on Mars or be a threat to the spacecraft in Mars orbit. Studies in 2014 showed the threat to orbiting spacecraft to be minimal. The greatest threat would be about 100 minutes after closest approach.
How long will it be until comet C 2013 a1 Siding Spring returns to the inner solar system?
about 740,000 years
According to current estimates, its next visit will be in about 740,000 years.

The atmosphere of a comet, called its “coma,” is made of gas and dust that spew out of the sun-warmed nucleus. The atmosphere of a typical comet is wider than Jupiter.
What year will Halley’s comet return?
2061
Astronomers have now linked the comet’s appearances to observations dating back more than 2,000 years. Halley was last seen in Earth’s skies in 1986 and was met in space by an international fleet of spacecraft. It will return in 2061 on its regular 76-year journey around the Sun.
Can you buy a rock from Mars?

How often is Mars hit by meteors?
Mars Hit By Space Rocks 200 Times a Year. Small space rocks are carving fresh craters into the Martian surface more often than previously thought, researchers say. A new study finds that there are more than 200 asteroid impacts on the Red Planet every year.
Will comet C/2013 A1 Siding Spring impact Mars?
A NASA media telecon on Friday, Nov. 7, will provide initial science observations of comet C/2013 A1 Siding Spring’s close flyby of Mars and the impact on the Martian atmosphere. The imaging spectrometer on NASA’s Mars Reconnaissance Orbiter has provided an image of the coma surrounding a comet that flew near Mars this week.
What is the best image of a comet on Mars?
NASA’s Hubble Space Telescope has produced a unique composite image of comet Siding Spring as it made its never-before-seen close passage of a comet by Mars. A camera on NASA’s Mars Reconnaissance Orbiter has taken the highest-resolution image ever made of an Oort Cloud comet, taking advantage of the comet’s Mars flyby.
What did NASA’s Mars Reconnaissance Orbiter see on Mars?
NASA’s Mars Reconnaissance Orbiter, which has sent home more data about Mars than all other missions combined, is also now providing data about a comet that buzzed The Red Planet today (Oct. 19).
