 MISSION LAUNCH DATE:                                           MARS LANDING:
  Jul 30, 2020 11:50 UTC (in flight)                            Feb 18, 2021

 LAUNCH VEHICLE:
  Atlas V-541 from Cape Canaveral Air Force Station, Florida, USA

 BACKGROUND:
  This mission carries the Perseverance rover and Ingenuity Mars Helicopter

  Landing site is an ancient river delta for a lake that once filled Jezero 
  Crater (but is now dry).

  Sky-crane descent system.
 
 PERSEVERANCE ROVER
  Dimensions:  3 m long, 2.7 m wide, 2.2 m tall (similar to Curiosity)
  Mass      : 2015 kg (126 kg heavier than Curiosity)
  Power     : MMRTG (thermoelectic generator)
  Navigation: New Terrain Relative Navigation system
    
  Science Objectives
   * Look for habitability: 
       Identify past environments capable of supporting microbial life
   * Seek biosignatures:
       Seek signs of possible past microbial life in those habitable 
       environments, particularly vertain types of rocks known to preserve 
       signs of life over time
   * Cache samples:
       Collect core rock and "soil" samples and store them on the Martian 
        surface
   * Prepare for humans:
       Test oxygen production from the Martian atmosphere

 INGENUITY (MARS HELICOPTER)
  This experimental autonomous aircraft, carried to Mars attached to the 
  belly of the Perseverance rover,  will test powered flight in the thin
  Martian atmosphere, which is about 1% as thick as Earth's, or comparable
  to an altitude of 100,000 feet on Earth. 
 
  Counter-rotating blades spin at 2400 rpm. Equipped with computers, 
  navigation sensors, internal heaters, and two cameras (color and 
  black-and-white), this engineering test aircraft will provide information 
  to inform decisions on small helicopters for future Mars missions.

   Dimensions: 0.49 meters (~19 inches)
   Rotor span: 1.2 meters (~4 feet)
   Mass      : 1.8 kg
   Power     : solar, self-recharging

  After receiving commands from Earth, relayed by Perseverance rover, the
  test flight(s) are performed without further real-time input.

 SPACECRAFT TRAJECTORY: 
  Post-launch fit to tracking data. Trajectory starts about an hour after
  launch, after probe separation.
