NASA and Northrop Grumman are targeting 5:56 p.m. EDT, Tuesday, Aug. 10, for the company’s 16th commercial resupply services mission to the International Space Station. Live coverage of the launch from NASA’s Wallops Flight Facility in Wallops Island, Virginia, will air on NASA Television, the NASA app, and the agency’s websitebeginning at 5:30 p.m. NASA also will hold a prelaunch news briefing Monday, Aug. 9.

Loaded with more than 8,200 pounds of research, crew supplies and hardware, Northrop Grumman’s Cygnus cargo spacecraft will launch on the company’s Antares rocket from Virginia Space’s Mid-Atlantic Regional Spaceport.

The Cygnus spacecraft, dubbed the SS Ellison Onizuka in honor of the first Asian American astronaut, will arrive at the space station Thursday, Aug. 12. At about 6:10 a.m., Expedition 65 NASA astronaut Megan McArthur will capture Cygnus with the station’s robotic arm, and ESA (European Space Agency) astronaut Thomas Pesquet will support her. After Cygnus capture, mission control in Houston will send ground commands for the station’s arm to rotate and install the cargo spacecraft on the Earth-facing port of the station’s Unity module.

Cargo resupply from U.S. companies ensures a national capability to deliver critical science research to the space station, significantly increasing NASA’s ability to conduct new investigations at this laboratory in space. Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. This Cygnus carries experiments that demonstrate 3D printing with dust, use engineered tissue to study muscle loss, and analyze growth of slime mold.

Cygnus also will carry a new mounting bracket that astronauts will attach to the port side of the station’s backbone truss during a spacewalk planned for late August. The mounting bracket will enable the installation of one of the next pair of new solar arrays at a later date.
