NASA has opened media accreditation for the Northrop Grumman CRS-25 mission, which will launch the company's Cygnus XL cargo spacecraft to the International Space Station on a SpaceX Falcon 9 rocket. This is an announced, future mission, not a completed launch; liftoff is targeted for no earlier than 10:49 a.m. EST on Sunday, Nov. 29, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
Why it matters
The mission is a routine but strategically important cargo resupply flight, carrying research that includes hardware for making tiny DNA-inspired particles in orbit. It reflects the continued reliance on U.S. commercial providers to keep scientific work on the station running.
The Cygnus XL is the 25th spacecraft Northrop Grumman has built under its NASA contract to deliver supplies to the International Space Station, which has been continuously occupied for 26 years. The mission will launch on a SpaceX Falcon 9 rocket, and the stub does not report payload mass or other performance specifications.
The players
NASA
The U.S. space agency that operates the International Space Station and contracts commercial companies to deliver cargo to it.
Northrop Grumman
A U.S. aerospace company that builds the Cygnus spacecraft used for station cargo resupply under its NASA contract.
SpaceX
The commercial rocket company whose Falcon 9 launch vehicle will carry the Cygnus XL to orbit.
The details
Cygnus will be launched on a Falcon 9 and then captured by astronauts using the Canadarm2 robotic arm, the station's large remotely operated robotic arm. Once captured, it will be installed on the Unity module's Earth-facing port, where its cargo can be unloaded. The spacecraft is expected to carry several new experiments, including hardware for manufacturing tiny DNA-inspired particles in space and human muscle cells and medications for testing therapies against muscle loss.
Timeline
Nov. 12, 2026, 11:59 p.m. EST: deadline for U.S. citizen media accreditation applications.
Nov. 29, 2026, 10:49 a.m. EST: targeted liftoff of Cygnus on a Falcon 9 rocket.
May 2027: Cygnus is scheduled to depart the space station.
The Tech Race
The Cygnus XL extends Northrop Grumman's contracted line of station resupply vehicles, which has been a central part of NASA's effort to rely on commercial providers for orbital cargo. The mission's research, including DNA-inspired particle manufacturing and muscle-loss therapeutics, reflects the station's use as a testbed for work that is not possible on Earth.
Members of the public who want to cover the launch in person must submit media accreditation by the Nov. 12 deadline, and the launch is targeted for Nov. 29 from Florida. The mission's experiments could eventually affect future cancer and osteoarthritis drug delivery methods, though these benefits are projected rather than demonstrated.
The takeaway
Watch whether the Nov. 29 liftoff occurs on schedule and whether Cygnus is captured and installed at the Unity module's Earth-facing port as planned. Those milestones will show whether the mission's experiments reach the station as scheduled.
What happens next
Media accreditation applications for U.S. citizens are due by 11:59 p.m. EST on Nov. 12, ahead of the targeted Nov. 29 liftoff from Cape Canaveral. The Cygnus spacecraft is scheduled to remain at the station until May 2027.
