Welcome to the SOFIA Science Center

Cycle 7 Call for Proposals Released!


Latest Update

Updates to sensitivity values in the HAWC+ chapter of the Observer’s Handbook and SITE were completed on August 3, 2018 to reflect final commissioning analysis based on Cycle 5 and Cycle 6 observations. Cycle 7 proposers are encouraged to verify their exposure time estimates for HAWC+ and FIFI-LS.

Additionally, for normal proposals longer than nine pages and SOFIA legacy proposals longer than 16 pages, DCS will return a warning that the proposal document is too long. If all individual section limits listed in the Call for Proposals documents have been adhered to, this warning may be ignored.

For all Cycle 7 major updates, visit the Cycle 7 webpage.

Cycle 7 timeline

Cycle 7 will feature two Calls for Proposals issued by the Universities Space Research Association (USRA) to solicit observing proposals from the U.S. and international astronomical communities. Proposals for both calls are due Septemeber 7, 2018 and observations are expected to begin April 27, 2019. Approximately 400 hours of observing time are available for regular observing proposals, with $4M in funding available to support guest observers based in the US. Thesis enabling proposals intended to enable and support PhD theses based on SOFIA data will be supported, with highly ranked proposals in this category eligible for up to two years of graduate student support.

In addition to the regular Call for Proposals, Cycle 7 will host a second call to premiere the SOFIA Legacy Program to enable programs spanning two cycles. Each cycle will utilize approximately 50 hours of the 100 total available hours for the Legacy Program for Cycle 7. $1M will be available to support Legacy Programs.

There is an additional call for those affiliated with German institutions administered by the German SOFIA Institute (Deutsches SOFIA Institut; DSI) on behalf of the German Aerospace Center (Deutsches Zentrum für Luft und Raumfahrt; DLR) that will offer an additional approximately 70 hours of observing time.

The Proposal Resources page contains all necessary documentation and useful tools for submitting proposals, including the following documentation for Cycle 7:
