SpaceX Falcon 9 Launches Northrop Grumman Cygnus XL to ISS With 11,000 Pounds of Cargo

Overview

• Cygnus XL S.S. Steven R. Nagel, which launched Saturday at 7:41 a.m. EDT from Cape Canaveral, is on course to the International Space Station after a successful Falcon 9 flight and booster landing at Landing Zone 40.
• The station’s Canadarm2 is set to capture the spacecraft Monday at 12:50 p.m. Eastern, with NASA astronauts Jack Hathaway and Chris Williams operating the arm before berthing to the Unity module’s Earth-facing port.
• The ship carries about 11,000 pounds of cargo that includes a Cold Atom Laboratory upgrade to trap and cool atoms to near absolute zero for quantum sensing research and possible dark-matter searches.
• Other investigations include gear to scale up therapeutic stem-cell production, tiny worms to study the gut microbiome in microgravity, and a radio receiver to improve space‑weather models that protect GPS and radar.
• External and educational payloads include ClimCam for East African weather imaging on the European Columbus platform and the student-built LEOPARDSat‑1 CubeSat for radiation shielding tests; the craft will stay until October before a trash‑disposal re-entry, marking the fourth straight Cygnus launched on Falcon 9 as Northrop readies Antares 330.
