 NOTE (2014-Jun-10):
  C/2013 A1 (Siding Spring) will have its closest approach to Mars on Oct 19, 
  2014 at a distance of about 135,000 km. 
  
  Location of predicted MRO minimum risk from comet particles 
  (occultation mid-point):

   Latitude: 7.6083 deg
   Time:     19-OCT-2014 20:08:07.182392952 ET (CSS CA + 98 min)

 MISSION LAUNCH DATE:                                        MARS ARRIVAL DATE:
  Aug 12, 2005 11:43 UTC (it's up and away)                  March 10, 2006

  Notes:  Aug 10, 2005: Original launch was scrubbed (gyros)
          Aug 11, 2005: Second attemped was launch scrubbed (fueling sensors)

 LAUNCH VEHICLE:
  Atlas V two-stage. Separation from Centaur: 2005-Aug-12 12:40:51.68 UTC

 BACKGROUND:
  MRO aerobraked for 6 months from the post-insertion 35 hour orbit, saving 
  450 kg of fuel. Primary science phase starts in November of 2006 and 
  nominally operates for 2 Earth years from a 112 minute, near circular polar 
  orbit. 

 SPACECRAFT PHYSICAL PROPERTIES:
  Height=  6.5 m                          Solar panels =   20 m^2
  Width = 13.6 m (tip-to-tip)             launch weight= 2180 kg

 SPACECRAFT TRAJECTORY: 
  Trajectory starts after Centaur launch stage separation (cruise phase).
  Trajectory after 2026-Sep-13 is PREDICTION.
