May 9, 2017 – NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA, issued its Cycle 6 Call for Proposals, on May 1, 2017, soliciting observing proposals from the U.S. and international astronomical communities. Approximately 500 hours of observing time will be awarded. The call for proposals was issued by the Universities Space Research Association (USRA) on behalf of NASA.
There will be a formal update to the call for proposals on June 5, 2017, that incorporates any changes based on information about the observatory obtained after the initial release of the call. The deadline for submitting the Phase I proposals is June 30, 2017, 21:00 PDT.
SOFIA is the largest airborne observatory in the world, capable of making observations that are impossible for even the largest and highest ground-based telescopes. SOFIA is a joint project of NASA and the German Aerospace Center (DLR).
