NASA’s Boeing 777 has returned to the agency’s fleet after undergoing heavy structural modifications as it transforms from a giant passenger plane into the agency’s next-generation airborne science laboratory. After a check flight and a three-hour transit from Waco, the aircraft returned to NASA’s Langley Research Center in Hampton, Virginia, on April 22.Since January 2025, the aircraft has been in Texas receiving hardware and structural upgrades to prepare for science operations. The modifications include installing dedicated research stations and extensive wiring. This allows payload systems to communicate with sensors such as lidar and infrared imaging spectrometers during flights. Cabin windows were enlarged and open portals installed at the bottom of the fuselage to mount remote-sensing instruments.
“Airborne missions at NASA use cutting-edge instruments to explore and understand our home planet,” said Derek Rutovic, program manager for the Airborne Science Program at NASA Headquarters in Washington. “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.”
Acquired in 2022 to succeed NASA’s retired DC-8 aircraft, the 777 will expand the agency’s airborne research capacity. It can accommodate 50 to 100 operators and carry 75,000 pounds of equipment for flights lasting up to 18 hours.
“NASA’s DC-8 was an incredible workhorse for Earth science for nearly 40 years,” said Kirsten Boogaard …
