NASA is developing capabilities that will allow missions at high altitudes to take advantage of signals from Global Navigation Satellite System (GNSS) constellations — like GPS commonly used in the U.S. These signals — used on Earth for navigation and critical timing applications — could provide NASA’s Artemis missions to the Moon with reliable timing and navigation data. NASA’s Space Communications and Navigation (SCaN) program is developing the technologies that will support this goal.

KENNEDY SPACE CENTER, Fla., October 26, 2020 (CASIS PR) – When Northrop Grumman launched its Cygnus spacecraft to the International Space Station (ISS) on October 2, 2020, it was loaded with a multitude of research and technology development investigations to be carried out onboard the orbiting laboratory.

Once Cygnus berthed with the space station three days later and its contents were unloaded by the astronauts onboard, it was time to start performing some of the science that flew on Northrop Grumman’s 14th commercial resupply services (CRS) mission.

HOUSTON (NASA PR) — The Northrop Grumman Cygnus spacecraft was bolted into place on the International Space Station’s Earth-facing port of the Unity module at 8:01 a.m. EDT while the spacecraft were flying about 261 miles above the South Pacific Ocean.

At 5:32 a.m. EDT, Expedition 63 Commander Chris Cassidy of NASA used the International Space Station’s robotic Canadarm2 to grapple the Northrop Grumman Cygnus spacecraft as Ivan Vagner of Roscosmos monitored Cygnus systems during its approach. 

The spacecraft’s arrival brings close to 8,000 pounds of scientific investigations, technology demonstrations, commercial products, and other cargo. 

The Cygnus spacecraft for this resupply mission is named in honor of Kalpana Chawla, who made history at NASA as the first female astronaut of Indian descent. Chawla, who dedicated her life to understanding flight dynamics, lost her life during the STS-107 mission when the space shuttle Columbia disintegrated upon reentering Earth’s atmosphere

Cygnus will remain at the space station until its departure in mid-December. Following departure, the Saffire-V experiment will be conducted prior to Cygnus deorbit and disposing of several tons of trash during a fiery re-entry into Earth’s atmosphere approximately two weeks later.
