<\/a>About four months after delivering several tons of scientific experiments and supplies to the International Space Station<\/a>, Northrop Grumman\u2019s uncrewed Cygnus cargo spacecraft is scheduled to depart the orbiting laboratory Tuesday, June 29. This morning, flight controllers on the ground sent commands to use the Canadarm2 robotic arm to robotically detach Cygnus from the Earth-facing port of the Unity module and maneuver it into place.<\/p>\n Live coverage of the spacecraft\u2019s release will air on NASA Television and the agency\u2019s website<\/a>, and the NASA app<\/a> beginning at noon EDT, with its release from the robotic arm scheduled for 12:25 p.m.<\/p>\n NASA astronaut Megan<\/a> McArthur will monitor Cygnus\u2019 systems upon its departure from the space station.<\/p>\n The Cygnus resupply spacecraft is named after NASA mathematician Katherine Johnson<\/a>, a Black woman who<\/strong> broke through barriers of gender and race, calculating orbital mechanics for some of the first U.S. human spaceflights.<\/p>\n Cygnus arrived at the International Space Station Feb. 22 with nearly 8,000 pounds of scientific investigations<\/a> and supplies following a launch<\/a> two days prior on Northrop Grumman\u2019s Antares rocket from NASA\u2019s Wallops Flight Facility on Wallops Island, Virginia. It was the company\u2019s 15th commercial resupply services mission to the space station for NASA.<\/p>\n For departure coverage and more information about the mission, visit: https:\/\/blogs.nasa.gov\/spacestation\/<\/a>.
