 BACKGROUND:
  NASA's Europa Clipper spacecraft will carry a suite of science instruments 
  to assess habitability of Jupiter's ice-covered moon Europa (502) while
  confirming the existence and nature of an expected sub-surface ocean.

  Launched            : 2024-Oct-14 16:06 UTC (SpaceX Falcon Heavy, KSC LC-39A)
  Mars gravity assist : 2025-Mar-01
  Earth gravity assist: 2026-Dec-03
         Arrival      : 2030-Apr-11 (5.50 year time-of-flight)
  Mission length      : 4.12 years (prime mission, JOI to E49)
  End-of-mission      : 2034-Sep   (directed to Ganymede impact ~30d after E49)

  The spacecraft is expected to orbit Jupiter 75 times and conduct 49 flybys 
  of Europa at altitudes as low as 25 km. This will reduce exposure to the high
  levels of radiation Europa moves within.

  Gravity-assists from Europa (49), Ganymede (7), and Callisto (9) will be used
  to target different Europa close approach points on each flyby.

 SPACECRAFT:
  Considering solar arrays and radar antennas, Europa Clipper will be the
  largest spacecraft NASA has developed to-date for an interplanetary mission. 
  When arrays are deployed, the spacecraft will span 30.5 meters.

  Main body (bus): 3 x 4.7 x 4 meters
  Dry mass (no propellant): 3241 kg
  Propellant: 2750 kg
  Solar power arrays: 2 x 14.2 x 4.1 meters

  Europa Imaging System (EIS)
  Europa Thermal Emission Imaging System (E-THEMIS)
  Europa Ultraviolet Spectrograph (Europa-UVS)
  Mapping Imaging Spectrometer for Europa (MISE)
