Cargo ship Cygnus XL leaves the space station and heads for a planned fiery end

Status
Confirmed. NASA's space-station blog, Oct. 9, 2026, and a NASA Ames article the same day on the heat-shield capsules.
Northrop Grumman's Cygnus XL cargo ship left the International Space Station on Friday when the station's robotic arm let it go at 12:44 p.m. Eastern, NASA said. It had been docked for nearly six months. Flight controllers plan to steer it into the atmosphere on Monday, where it will burn up with trash from the station. NASA will not show that live. On board are 12 small test capsules carrying new heat-shield materials. They will gather data as the ship falls.
NASA's station blog says the arm released the ship from the Earth-facing port of the Unity module. It had arrived with about 11,000 pounds of supplies and research. Controllers will command the deorbit on Monday, Oct. 12. No clock time for the deorbit was given. An earlier NASA calendar had listed release at 12:45 p.m. The blog says 12:44 p.m.
The capsule experiment is the Kentucky Reentry Probe Experiment, called KREPE-3, the third in a series. NASA Ames says it is run with the University of Kentucky, the state of Kentucky, and NASA's EPSCoR program. One capsule holds a 3D-printed heat shield designed at NASA's Johnson Space Center. Results are not in yet.
What is still unknown or disputed
- The deorbit time on Monday.
- What the heat-shield capsules measured. Results are not posted.
