BackForward Satellite Programme: Interstellar Mapping and Acceleration Probe 

Programme details
Programme description
  • IMAP a spin stabilised satellite at the L1 Lagrange point orbiting the sun with a science payload of 10 instruments for heliophysics. 
  • Part of the NASA solar terrestrial probes programme to provide real time data for space weather predictions
  • IMAP is being developed with Princeton University
  • IMAP Mission Operation Center at Johns Hopkins University Applied Physics Laboratory, which will operate the spacecraft. 
  • Planned duration of 3 years.
  • More details here and here
Data circulation
  • IMAP will supply critical real-time space weather data through its "IMAP Active Link for Real-Time" or I-ALiRT. 
  • All science and other data will be shared with the heliophysics community
  • The NASA Space Physics Data Facility (SPDF) is the final archive for IMAP with regular transfer of data to the SPDF so that the data can be made available.
