 NOTE: 
  There has been no contact with the MAVEN spacecraft since December 6, 2025 
  with some evidence it experienced an unplanned delta-V Dec. 4 and is spinning
  in an altered trajectory. Therefore predicts after December 4, 2025 may be 
  inaccurate.

 LAUNCH DATE:                                    MARS ARRIVAL DATE:
 Nov 18, 2013 @ 18:28 UTC                        September 22, 2014 @ 02:24 UTC
 Trajectory here begins after stage separation.

 LAUNCH VEHICLE:
  Atlas V-401
   ("4" means 4-meter enclosure fairing, "0" means 0 strap-on boosters, 
    "1" means the Centaur stage has one engine) 
  Cape Canaveral Air Force Station, Florida, USA
  Space Launch Complex 41 (SLC-41)

  Centaur separation at 52m 42.2s after launch, over the western coast
  of Australia.

 BACKGROUND:
  The Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft orbits Mars
  to explore the upper atmosphere of the planet, study its nature and the
  role solar activity plays in atmospheric loss over time, providing insight   
  into the history of Mars' atmosphere and climate, liquid water, and planetary 
  habitability.  

  After capture into Martian orbit, it took 5 weeks for the spacecraft to reach 
  its final science-mapping orbit, test the instruments, and test science 
  mapping sequences. After the commissioning phase, MAVEN had a 1-Earth-year 
  primary mission during which it made its key measurements.

  The science orbit is an ellipse 150 x 6200 km having a 75 degree inclination 
  with respect to the Martian equator. At its lowest point, it passed through 
  the atmosphere and directly sample gas composition. At its highest point, 
  it can carry out ultraviolet imaging of the entire planet. Five "deep dips" 
  made measurements down to 125 km.

 SCIENCE INSTRUMENTS:
  Particles and Fields Package (PFP)
   Solar Energetic Particle (SEP)
   Solar Wind Ion Analyzer (SWIA)
   Solar Wind Electron Analyzer (SWEA)
   SupraThermal and Thermal Ion Composition (STATIC)
   Langmuir Probe and Waves (LPW)
   Magnetometer (MAG)
  Imaging Ultraviolet Spectrometer
  Neutral Gas and Ion Mass Spectrometer (NGIMS)

 SPACECRAFT PHYSICAL PROPERTIES:
  Solar-powered, with a high-gain antenna that can be pointed to Earth for
  twice-weekly communications sessions.

  Length: 37.5 feet (11.4 meters)
  Spacecraft dry mass: 1991 pounds max (903 kilograms)
  Wet (Fueled) mass at launch: 5622 pounds max (2550 kilograms)
  Power: 1135 watts (when Mars is furthest from the Sun)

 SPACECRAFT TRAJECTORY (JPL navigation):
   Trajectory begins after Centaur booster stage separation. 
   Fit to data through 2025-Dec-04, prediction thereafter.
