In a significant event for space exploration, the Northrop Grumman Cygnus spacecraft is scheduled to depart the International Space Station (ISS) on Friday, Dec. 22. This departure marks not just the end of its four-month tenure at the ISS but also a pivotal moment in the ongoing collaboration between NASA and its international partners. The Cygnus spacecraft, after delivering over 8,200 pounds of essential supplies and scientific equipment, is now set to embark on the final phase of its journey.
Cygnus’ Mission at the ISS
The spacecraft arrived at the space station on Aug. 4, following a successful launch on Northrop Grumman’s Antares rocket from NASA’s Wallops Flight Facility in Virginia. Since then, Cygnus has played a crucial role in not only resupplying the station but also in carrying out scientific investigations and technological experiments. This mission, the 19th commercial resupply service to the ISS by Northrop Grumman, underscores the critical importance of private-public partnerships in advancing space research and exploration.
Live Coverage of the Departure
NASA has announced that live coverage of the Cygnus spacecraft’s departure will begin at 7:45 a.m. EST on the NASA+ streaming service, including NASA Television, the NASA app, YouTube, and the agency’s website. This offers an unprecedented opportunity for enthusiasts and the public to witness a key operation in space mission management.
The Role of Technology and Astronauts
The departure will involve the use of the space station’s Canadarm2 robotic arm, which will detach Cygnus from the Unity module’s Earth-facing port. NASA astronaut Loral O’Hara will be closely monitoring the systems of Cygnus upon its departure, showcasing the blend of human skills and robotic technology in space operations. O’Hara’s role is vital in ensuring the successful completion of this phase of the mission.
The Final Journey
Following its departure, Cygnus will undergo a deorbit engine firing in early January, leading to a planned destructive re-entry. This phase of the mission is as critical as any, with the spacecraft – filled with trash from the station – set to safely burn up in Earth’s atmosphere. This efficient disposal method highlights the ongoing efforts to manage space debris responsibly.
Honoring Astronaut Laurel Clark
In a touching tribute, Northrop Grumman named this spacecraft after the late NASA astronaut Laurel Clark. Clark, who contributed immensely to space exploration, continues to inspire future missions and explorations.
