NASA Receives Modified Boeing 777 Flying Laboratory at Langley Research Center

NASA has received its new flying laboratory, a modified Boeing 777 airliner that arrived at the agency's Langley Research Center in Hampton, Virginia, on April 22, 2026. The Boeing 777 completed a check flight and a three-hour transit from Waco, Texas, where it underwent extensive structural modifications. L3Harris, which handled the modifications, delivered the aircraft ahead of schedule.

The Boeing 777, a 777-200ER model manufactured in 2003, was previously flown by Japan Airlines under the registration JA704J. It saw commercial service before going into storage in Southern California in 2020. NASA bought the aircraft in December 2022 for less than $30 million.

The plane underwent an initial series of modifications at NASA Langley Research Center before arriving in Waco in January 2025. L3Harris partnered with Yulista on the modification work, accelerating the program using advanced engineering techniques including 3D scanning and specialized installation tooling. Nearly 35,000 precision holes were drilled into the belly of the aircraft.

Modifications in Waco included the installation of dedicated research stations, extensive wiring, enlarged cabin windows, and ports in the bottom of the fuselage to mount remote-sensing instruments. The Boeing 777 also received new power, data, and communications systems, along with accommodations for instrument operators.

Wiring harnesses in the fuselage allow operators' workstations to communicate with sensors such as LIDAR and infrared imaging spectrometers during flights.

Research station and wiring upgrades in the cabin are being performed by NASA and HII. The Boeing 777 will accommodate between 50 and 100 onboard operators. It offers a useful payload of 75,000 pounds and can conduct missions of up to 18 hours at a maximum altitude of 43,000 feet.

The Boeing 777 will become NASA’s largest research aircraft platform, taking over from the agency’s retired Douglas DC-8. The DC-8, from 1969, accommodated 45 researchers and flight crew, could carry 30,000 pounds of scientific instruments and equipment, and typically conducted missions lasting between six and 10 hours.

NASA retired the DC-8 after it returned to Armstrong Flight Research Center in Palmdale, California, on April 1, 2024, following its final test mission.

The Boeing 777 carries the registration N577NA. It will be used for gathering Earth science data, including using sensors to monitor activities and phenomena on the surface of the globe, such as studying polar ice fields and monitoring wildfires. Earth sciences missions will involve remote sensing and gas sampling instruments.

Airborne missions at NASA use cutting-edge instruments to explore and understand our home planet. The 777 will be the largest airborne research laboratory in our fleet, collecting data to improve life on our home planet and extend our knowledge of the Earth system as a whole.

I’m excited for what the 777 will bring. Being part of that team, I got to see the impact up close. It gives us the ability to bring together more partners, more educational opportunities, and more instruments. That will make a real difference in the data we collect moving forward.

The Boeing 777 will primarily be used for airborne science campaigns but will support a variety of other mission requests as the aircraft is available, similar to the DC-8, a NASA spokesperson said. The DC-8’s mission spectrum included sensor development, satellite sensor verification, telemetry data retrieval, optical tracking for space vehicle launch and re-entry, and research studies of the Earth’s surface and atmosphere.

The Boeing 777 is expected to fly its first science mission in January 2027 as part of the North American Upstream Feature-Resolving and Tropopause Uncertainty Reconnaissance Experiment (NURTURE). The NURTURE mission will involve studying high-impact winter weather events, including severe cold air outbreaks, wind, snow and ice storms, and hazardous seas.

It will gather data in North America, Europe, Greenland, and the Arctic and North Atlantic Oceans.

The NURTURE payload has been installed on the Boeing 777 alongside general modification work. NASA also retired the Stratospheric Observatory for Infrared Astronomy (SOFIA), a Boeing 747SP, in 2022. The War Zone reported these details on the Boeing 777's modifications and capabilities.
