Aircraft List

The NASA Airborne Science Program provides a unique set of NASA supported 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, 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

Non-NASA Aircraft
NASA instrumentation may fly on non-NASA Federal aircraft as well as academic and commercial platforms for which agreements for access by SMD investigators are in place, in process, or have recently been approved by NASA Aviation Management as airworthy and safe to operate. For more information, please review the current ASP Call Letter for further requirements and guidance. Please note that in addition to filing the required Flight Request, investigators are responsible for contacting vendors to determine if the platform meets the requirements of the proposed scientific investigation. It is also 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.

Grob G-520 Egrett

Raytheon Flight Test Operation’s EGRETT II aircraft is an all composite, multi-purpose, single turboprop engine, high aspect ratio, mid-wing platform specifically designed to accommodate a wide variety of electro-optical, radar, LIDAR, SIGINT, and scientific / research payloads for high altitude, long endurance, applications.

The aircraft can operate from most paved runways. No special airport infrastructure is required. The aircraft has dual GPS and is all-weather (IFR/icing) capable and is dual certified as both an EXPERIMENTAL and NORMAL aircraft under US regulations.

Twelve non-pressurized equipment bays, totaling 225 cubic feet, are distributed throughout the fuselage and can be configured, in modular packages, to accept various customer payloads or adapt to changing mission requirements. The equipment bays are ventilated and heated or cooled as necessary to maintain a temperature controlled environment. The entire lower portion of the fuselage is non-structural greatly simplifying ease of access and modification of the aircraft for unusual side or downward looking payload configurations.
