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. || ",

C/2013 A1, better known as Comet Siding Spring, will make a remarkably close pass of Mars on October 19, 2014. At closest approach, Comet Siding Spring will come within 82,000 miles of the Red Planet – just one-third of the distance from the Earth to the Moon. During the flyby, NASA will position its Mars fleet both to protect it from comet dust, and to make observations of the comet and its effects on the upper atmosphere of Mars. || ",

            "description": "The Tracking Data Relay Satellite (TDRS) fleet has provided spacecraft communications and tracking since the 1980's. Designed to replace most ground stations and provide longer periods of coverage, TDRS spacecraft have become an indispensable component of both manned and unmanned Earth orbiting space missions.This visualization begins by showing how a typical spacecract (NIMBUS-7) communicated with the ground before TDRS. The spacecraft occassionally communicated with ground stations as its orbit briefly took it within range. This required ground stations to be spread all over the world and only allowed for sporatic communications between spacecraft and the ground.As the animation continues, the TDRS fleet of spacecraft are introduced and a typical modern-day spacecraft, the Tropical Rainfall Measuring Mission (TRMM), is also introduced. As TRMM orbits the Earth, various TDRS spacrecraft are able to track and communicate with TRMM. This contact could be continuous, but for most spacecraft, continuous coverage is unnecessary. Constant communications between TDRS spacecraft and ground stations at White Sands and Guam are shown.The visualization then adds many of the other TDRS users and shows how they communicate.An additional (\"extra\") visualizaiton of the TDRS fleet communicating with user spacecraft is provided from a slightly different angle. These animations were created for a video supporting the launch of TDRS-12 (also called TDRS-L). || ",
