IMAGE Early Orbit Operations Going Well

IMAGE Early Orbit Operations Going Well!

• Spacecraft All sub-systems are healthy and
  operating nominally
• Re-orientation with spin-axis to normal completed
• Nutation eliminated with magnetic torquer
  procedure
• Real-time and store/dump telemetry modes tested
  and nominal
• Instruments All instruments are working
  nominally and out-gassing high voltages have
  been cycled on
• HENA high energy neutral atom camera. (APL)
• MENA medium energy neutral atom camera. (SwRI)
• LENA low energy neutral atom camera (GSFC)
• EUV extreme UV cold plasma (He) camera. (UAz)
• FUV far UV (auroral) camera. (UCB)
• RPI radio plasma imager. (UML)
• Planning for a first light press conference at
  AGU
• Science measurement will begin on May 15, 2000

Instrument Checkout Preliminary, uncalibrated,
uncorrected images

• RPI echoes with 200 m antennas

• HENA neutral mass spectrum and 2 Ring current
  images

• EUV (3-heads) observations of the Plasmasphere

Instrument Checkout - Auroral Observations

• Wideband Imaging Camera over 140-160 nm (LBH
  band)

• Oxygen Aurora at 135.6 nm

• Proton Aurora at the Doppler shifted Lyman
  H-alpha line at 121.82 nm
