(CNN) -- The comet Siding Spring whizzed within 87,000 miles of Mars on Sunday -- close enough to the Red Planet that the fleet of spacecraft orbiting Mars 'ducked' for cover.
But not before gathering some data.
NASA took the precaution of having the spacecraft move behind the planet to avoid getting hit by Siding Spring's trail of dust and gas.
A new NASA spacecraft called MAVEN, short for Mars Atmosphere and Volatile Evolution, will help scientists figure out what happened to the red planet's atmosphere. Its elliptical orbit will allow it to pass through and sample the entire upper atmosphere of Mars.

It made observations of the comet before sheltering behind Mars, NASA said in a news release.
'The spacecraft performed flawlessly throughout the comet flyby,' said Mars Reconnaissance Orbiter Project Manager Dan Johnston of NASA's Jet Propulsion Laboratory. 'It maneuvered for the planned observations of the comet and emerged unscathed.'
The Mars Reconnaissance Orbiter immediately began to transmit information to Earth, but the full downlink could take days, NASA said.
Siding Spring sped by Mars at a speed of about 126,000 miles per hour.
The comet does not pose a threat to Earth and was headed back out to the outer reaches of the solar system, according to NASA.
Hours after the comet passed at its closest point to Mars, NASA was still awaiting confirmation on the status of the Mars Odyssey orbiter and the new Mars Atmosphere and Volatile EvolutioN (MAVEN).

Several Earth-based and space telescopes, including the Hubble Space Telescope, also took pictures.
The NASA rovers that are on the surface of Mars were protected by Mars' atmosphere, NASA said.

Comet Siding Spring is expected to come within 87,000 miles of Mars at about 2:27 p.m. ET on Sunday -- very close for a comet flyby. The space rock is moving at about 126,000 mph (56 kilometers per second).
