Key Takeaways:

NASA is converting a modified Boeing 777-200ER into its largest flying science laboratory, replacing the retired Douglas DC-8 after 37 years of service.
The 777 offers significant upgrades over the DC-8, including increased capacity for personnel and equipment, a longer range (9,000 nm vs. 5,400 nm), and higher operational altitude and flight duration.
After extensive structural modifications, the aircraft is undergoing final outfitting at NASA's Langley Research Center for its debut mission, NURTURE, in January 2027, which will study cold weather phenomena across North America, Europe, and the Arctic.

A heavily modified Boeing 777-200ER formerly operated by Japan Air Lines will soon become NASA’s largest flying science laboratory.

The retired commercial jet arrived at NASA’s Langley Research Center in Virginia on Wednesday following a check flight and three-hour transit from Waco, Texas, where L3Harris since January 2025 had been making structural modifications. It will replace the space agency’s retired Douglas DC-8, which flew its final science mission in 2024 after 37 years in service.
