    "description": "This visualization shows active spacecraft orbiting Mars and their relationship to Comet Siding Spring.   The comet passes  very close to Mars on  October 19, 2014.  The camera is looking from the direction of the Sun towards Mars.  The camera is fixed to Mars and the orbit trail of Mars goes off to the right.As Comet Siding-Spring makes its way through the Martian neighborhood it reaches the closest distance at about 18:32 UT.   Debris left by the comet follows behind the comet on the line representing where the comet was.  This derbis impacts Mars at about 20:08 UT.    Scientists and engineers are concerned that the derbis may harm the spacecraft.  Several of the spacecraft have executed orbital maneuvers to put them on the opposite side of Mars when the debris impacts. || ",

            "description": "On October 19, Comet Siding Spring will pass within 88,000 miles of Mars – just one third of the distance from the Earth to the Moon! Traveling at 33 miles per second and weighing as much as a small mountain, the comet hails from the outer fringes of our solar system, originating in a region of icy debris known as the Oort cloud.Comets from the Oort cloud are both ancient and rare. Since this is Comet Siding Spring’s first trip through the inner solar system, scientists are excited to learn more about its composition and the effects of its gas and dust on the Mars upper atmosphere.NASA will be watching closely before, during, and after the flyby with its entire fleet of Mars orbiters and rovers, along with the Hubble Space Telescope and dozens of instruments on Earth. The encounter is certain to teach us more about Oort cloud comets, the Martian atmosphere, and the solar system’s earliest ingredients. || ",
