Congratulations to the whole MAVEN team for a successful orbit insertion yesterday. Here's a look at what we can expect for the next 7 weeks of the mission:

First week after MAVEN Mars Orbit Insertion (Sep 21-28)
  • Sep 22: MAVEN Transition to Transition Phase Configuration; possible IUVS observation
  • Sep 22: At 09:12 UTC, Mars Orbiter Mission test-fires its main engine
  • Sep 24: Periapsis Lowering Maneuver 1 -- a rocket burn at apoapsis will reduce the spacecraft's orbital energy and drop its periapsis closer to the planet
  • Sep 24: At 02:00 UTC, Mars Orbiter Mission arrives
  • Sep 26: MAVEN Period Reduction Maneuver 1 -- a rocket burn at periapsis will shrink the size of the orbit, lowering the apoapsis

Second week after MAVEN arrival (Sep 29-Oct 4)
  • Oct 2: Period Reduction Maneuver 2

Third week after MAVEN arrival (Oct 5-11)
  • Oct 5: Periapsis Lowering Maneuver 2
  • Oct 6: Particles and Fields package checkout; Periapse Time Estimation data collection
  • Oct 7: Neutral Gas and Ion Mass Spectrometer (NGIMS) pre-deploy checkout 1
  • Oct 9: Period Reduction Maneuver 3
  • Oct 10: Langmuir Probe and Wves (LPW) deployment
  • Oct 11: Articulated Payload Platform and Solar Wind Electron Analyzer (SWEA) deployment

Fourth week after MAVEN arrival (Oct 12-18)
  • Oct 13: Payload Platform calibration / Remote sensing instrument checkout
  • Oct 14: NGIMS checkout 2 / cover deploy
  • Oct 16: Comet Siding Spring science begins

Fifth week after MAVEN arrival (Oct 19-25)
  • Oct 19: At 18:32 UTC, Siding Spring passes by Mars
  • Oct 22: Post Siding Spring spacecraft checkouts
  • Oct 23: Periapsis Lowering Maneuver 3
  • Oct 24: Extreme Ultraviolet (EUV) scans

Sixth week after MAVEN arrival (Oct 26-Nov 1)
  • Oct 24: LPW sync and modes
  • Oct 28: Solar Energetic Particle (SEP) and Magnetometer (MAG) scans
  • Oct 29: Electra Bit Error Rate, Sniff, Switch exercise (Electra is not a science instrument; it is the communications relay for landed Mars missions like Curiosity and Opportunity.)
  • Oct 30: Periapsis Lowering Maneuver 4
  • Oct 31: Payload Platform calibration / Remote sensing instrument checkout repeat

Seventh week after MAVEN arrival (Nov 2-8)
  • Nov 3: LPW ping test
  • Nov 4: MAG roll
  • Nov 5: NGIMS checkout 3
  • Nov 6: Engineering dry run; Electra communications pass with Curiosity
  • Nov 7: Orbit trim maneuver 0
  • Nov 8: Science start
