Aircraft List

The NASA Airborne Science Program aircraft list provides unique NASA aircraft and commercial aircraft that benefit the earth science community. These manned and unmanned aircraft carry the sensors that provide data to support and augment NASA spaceborne missions.
Reminder: All investigators with approved or pending proposals from the Research Opportunities in Space and Earth Sciences (ROSES) announcements that have a requirement for a NASA Airborne Science platform/instrument, must submit a Flight Request. The Flight Request is also the method to acquire an estimate if your proposal requires a cost estimate for Airborne Science support. However, for investigators proposing to participate on large, multi-aircraft experiments, such as the ROSES Call 2015: KORUS-AQ (Korea US- Air Quality), a single Flight Request will be submitted for each mission by the Project Manager or Project Scientist. The Science Operations Flight Request System (SOFRS) can be reached directly at
For all "Commercial" aircraft, in addition to filing a Flight Request, investigators are responsible for contacting vendors to determine if the platform meets the requirements of the proposed scientific investigation. It is the responsibility of the investigator to ensure that before any preliminary test flights or actual data collection flights utilizing NASA personnel, instruments or funds occur, all vendors successfully complete a NASA airworthiness/flight safety review in accordance with NASA Aviation Safety Policy for Non-NASA Aircraft.

HU-25A Guardian

NASA Langley Dassault HU-25A Guardian

The Dassault HU-25C Guardian is a modified twin-engine business jet, based on the civilian Dassault FA-20G Falcon. The aircraft was previously used by the U.S. Coast Guard as a search-and-rescue platform. NASA acquired this aircraft in 2011 to provide a medium altitude, medium range platform for remote sensing instruments and satellite support. Payload accommodations include a nadir camera port, large search windows on each side of the fuselage, a hard point with pylon under each wing, provisions for mounting atmospheric sampling probes on the crown of the fuselage, and a nadir drop hatch (32 in. long x 19.7 in. wide).
