SOFIA Archival Research Program

The proposal call is closed. The deadline for submitting proposals was February 12, 2021, 21:00 PST (February 13, 2021, 5:00 UTC).

On December 4, 2020, the SOFIA program released a Call for Proposals for the SOFIA Archival Research Program (SARP). This program will fund archival research projects primarily using SOFIA data to encourage the use of available SOFIA archival data in the Infrared Science Archive (IRSA). Two distinct types of proposals for the archival research program are solicited in this round:

  • Regular Proposals - Large programs requesting up to $150,000 per year, or more in exceptional cases, and lasting up to two years
  • Small Proposals - Targeted programs requesting up to $50,000 and lasting for one year 

This call is open to all US institutions. This complements the Astrophysics Data Analysis Program (ADAP) under the NASA Research Opportunities in Space and Earth Sciences (ROSES) solicitation. More information.


Director's Discretionary Time

Suggestions for Director's Discretionary Time (DDT) observing projects are welcome at any time. Up to 7% of the observing time may be used for such projects. By default, any surplus DDT is used for already-accepted proposals from the annual proposal Call.


Cycle 9

The Cycle 9 proposal call is closed. The deadline for submitting proposals was September 4, 2020, 21:00 PDT (September 5, 2020, 4:00 UTC). Proposal selections were made in December 2020 and are listed here.

On June 2, 2020, the SOFIA program released two Calls for Proposals: one Call for regular proposals, and a separate Call for the SOFIA Legacy Program (SLP). Funding is available for Guest Observers with affiliations in the U.S.; the total available Guest Observer funding available for Cycle 9 is expected to be approximately $4M for regular proposals and $2M per year for SLP proposals. The Calls were issued on behalf of NASA by the Universities Space Research Association (USRA). Parallel calls for the German community were issued by the German SOFIA Institute (DSI; University of Stuttgart). A formal update to the Calls was released on July 24, 2020.

In addition, as part of the SOFIA Science Utilization Policies, a fraction of the observing time can be awarded by the Director as Director's Discretionary Time to handle observations that cannot be accommodated by the annual Call for Proposals. The policies and procedures are available at the above link.


Cycle 8

The Cycle 8 proposal call is closed.

The selected proposals are listed here.

On May 31, 2019, the SOFIA program released two Calls for Proposals with three types of proposal opportunities: one Call for regular proposals, and a separate Call for both the SOFIA Legacy Program (SLP) and the new SOFIA Archival Research Program (SARP). Funding is available for Guest Observers with affiliations in the U.S.; the total available Guest Observer funding available for Cycle 8 is expected to be approximately $4M for regular proposals, $1M per year for SLP proposals, and $300k for SARP proposals. The Calls were issued on behalf of NASA by the Universities Space Research Association (USRA). Parallel calls for the German community was issues by the German SOFIA Institute (DSI; University of Stuttgart). There were no changes made in the formal update to the Call for Proposals, released on July 20, 2019. The deadline for submitting proposals was September 6, 2019, 21:00 PDT (September 7, 2019, 4:00 UTC). There is a one-week extension in the deadline for submitting proposals for proposers directly affected by Hurricane Dorian. Contact the Science Mission Operations director Dr. Harold Yorke with a brief, specific, explanation to request the extension.

In addition, as part of the SOFIA Science Utilization Policies, a fraction of the observing time can be awarded by the Director as Director's Discretionary Time to handle observations that cannot be accommodated by the annual Call for Proposals. The policies and procedures are available at the above link.
