Past Proposal Calls

Cycle 4

The SOFIA Cycle 4 Call for Proposals, released on May 1, 2015 solicited observing proposals using SOFIA from the US and International astronomical communities for approximately 500 hours of observing time. It was issued on behalf of NASA by the Universities Space Research Association (USRA). Approximately 80 hours of observing time were offered via the German SOFIA Cycle 4 proposal call to astronomers affiliated with German institutions. The deadline for Phase I proposal submission to both US and German queues was July 10, 2015.

The Call for Proposals for observing with SOFIA during Cycle 3 was released on May 23, 2014. The deadline for submitting proposals was July 18, 2014. Observations will start in March 2015.


Cycle 2

The Call for Proposals for observing with SOFIA during Cycle 2 was released on April 29, 2013. The deadline for submitting proposals was June 28, 2013. Observations will take place during calendar year 2014.


Cycle 1

The Call for Proposals for observing with SOFIA during Cycle 1 was released in November, 2011. The deadline for submitting proposals was January 27, 2012, and the observations are scheduled to start in Spring, 2013.


Basic Science

"Basic Science" was the second phase of early science operations, following Short Science. The results of the Basic Science proposal call were announced in November, 2010, following an independent peer review of the proposals submitted. Basic Science flights began in June, 2011 and were completed in September, 2011.


Short Science

The flights for Short Science with FORCAST were completed in December, 2010 and the GREAT flights were completed in April, 2011.

In June 2008 the SOFIA project issued a call for participation in the very first scientific studies to be carried out by the observatory. Twenty-seven white papers were received. These were evaluated by a peer-review panel in the beginning of October. Based on their recommendations, the project has invited Dr. Paul Harvey (Univ. of Colorado, Boulder), Dr. Mark Morris (Univ. of California, Los Angeles) and Dr. David Neufeld (Johns Hopkins Univ.) to join the Short Science program. Drs. Harvey and Morris will collaborate with the FORCAST team, and Dr. Neufeld with the GREAT team. We congratulate them, and look forward to their participation in the SOFIA scientific program.
