A Northrop Grumman Antares rocket, carrying its Cygnus cargo spacecraft to the International Space Station, is awaiting liftoff this afternoon from Virginia Space’s Mid-Atlantic Regional Spaceport at Wallops Flight Facility in Virginia. The five-minute window for launch opens at 3:21 p.m. EST today.
The latest forecast stands at 90% favorable for launch, with the primary weather concern being the cloud ceiling.

Northrop Grumman’s 13th contracted cargo resupply mission with NASA will deliver about 7,500 pounds of science and research, crew supplies and vehicle hardware to the International Space Station. This mission’s science experiments include an experiment on viruses that can target specific bacteria, an investigation on bone loss in microgravity and more.
