Siding Spring Mars Spacecraft
This artist's concept shows NASA's Mars orbiters lining up behind the Red Planet for their "duck and cover" maneuver to shield them fro comet dust that may result from the close flyby of comet Siding Spring (C/2013 A1) on Oct. 19, 2014.

All three NASA orbiters around Mars confirmed their healthy status Sunday after each took shelter behind Mars during a period of risk from dust released by a passing comet.

Mars Odyssey, Mars Reconnaissance Orbiter and the Mars Atmosphere and Volatile Evolution (MAVEN) orbiter all are part of a campaign to study comet C/2013 A1 Siding Spring and possible effects on the Martian atmosphere from gases and dust released by the comet. The comet sped past Mars today much closer than any other known comet flyby of Mars or Earth.

Additional information about the precautions and observations by each of the three orbiters is at and

for Odyssey, Mars Reconnaissance Orbiter and MAVEN, respectively.
