Open Call: Cycle 10 calls and DDT proposals including the Flash Call for Far-Northern SOFIA/HAWC+ Observations

To stay up to dates with the latest programmatic updates, sign up for the e-Newsletter here.


Flash Call for Far-Northern SOFIA/HAWC+ Observations

Through this "Flash Call", the SOFIA program invites Director's Discretionary Time (DDT) proposals for observations with the HAWC+ instrument in the celestial region: 23 hr < RA < 10 hr for Dec>50 degrees, or any RA for Dec>75 degrees, to be observed in January-February 2022. A total of up to ~5h of observing time is available. These observations will balance the flight plans for already-accepted guest observer programs.Scientific observations with the FPI+ guide camera are also possible.

Proposals should be submitted through the USPOT tool, using the proposal process for Director's Discretionary Time observations. The Observers Handbook details properties of HAWC+.

Proposals are due on Nov 15, 2021, 11:59 pm PST. The proposals will be evaluated though an abbreviated, dual anonymous, review process. Proposers are therefore reminded to anonymize their texts accordingly.

Questions about the call or proposals can be addressed to the SOFIA Help desk: sofia_help@sofia.usra.edu.


Cycle 10

The calls for Cycle 10 observations are open as of October 29, 2021, with a deadline of January 28, 2022, 21:00 PST (January 29, 2022 4:00 UTC). Detailed information about the Cycle 10 calls can be found here.

Two Calls for Proposals are offered:

  • A Call for regular programs, for which approximately 550 hours of observing time is offered and funding up to $5.5M is expected to be available for eligible proposers
  • A Call for the SOFIA Legacy Program, which solicits observing programs that will enable a rich archival dataset of significant scientific value to the astronomical community. Up to three legacy proposals will be accepted, with each allocated up to ~200 hours of observing time (~100 hours of observations per cycle). Funding is expected to be available at the level of $2M per year.

All six instruments -- EXES, FIFI-LS, FORCAST, FPI+, GREAT, and HAWC+ -- will be available during the Cycle (October 1, 2022 to September 30, 2023). SOFIA plans to carry out three Southern deployments: a long deployment scheduled approximately June through September 2023 (GREAT and HAWC+), and two short deployments in November 2022 (FIFI-LS) and March 2023 (EXES). Formal updates to the Calls will be provided on December 10, 2021.


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.

DDT proposals are submitted through the USPOT tool, using the process described here.


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.


Flash Call for FORCAST Observations

The proposal call is closed.

The SOFIA program invites Director's Discretionary Time (DDT) proposals, through this "Flash Call", for observations with the FORCAST Long Wavelength Camera in the celestial region: RA, Dec: 13h - 19h, > +70˚, to be executed during flights at the end of June 2021. A total of up to ~6h of observing time is available, depending on detailed flight planning constraints. 

The defining observations for three of the flights in the upcoming SOFIA/FORCAST series (OC8O), June 28 - July 3, are of the Moon, using the Short Wavelength Camera. Because of array latency, scientific observations with that camera are not viable for the rest of each flight. Based on initial flight plans, a set of end-of-flight, return-legs are, however, available for observations with the Long Wavelength Camera (LWC), in imaging or grism mode. Scientific observations with the FPI+ camera are also possible.

Because the details of flight legs are only settled once flight plans are laid out (relatively close to the flight dates), the turn-around for this Flash Call is short and proposals are due by 11:59pm on Wednesday May 26, 2021 (PDT). More information.


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). Proposal selections were made in April 2021 and are listed here.

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.


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.
