NASA, Northrop Grumman, and SpaceX are accelerating the next commercial resupply flight to the International Space Station to maximize launch opportunities following an assessment of mission readiness. NASA now is targeting no earlier than 6:11 p.m. EDT, Sunday, Sept. 14, for the launch of a Northrop Grumman Cygnus XL on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
The Cygnus XL spacecraft will deliver more than 11,000 pounds of science, research, and supplies* to the orbital complex, including materials to produce semiconductor crystals in space and equipment to develop improvements for cryogenic fuel tanks. The spacecraft also will deliver a specialized UV light system to prevent biofilm growth and supplies to produce pharmaceutical crystals that could treat cancer and other diseases.NASA is targeting arrival of the Cygnus XL spacecraft and its installation aboard the space station on Wednesday, Sept. 17.
The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For almost 25 years, people have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration of the Moon and Mars.
