Today’s Wallops Range forecast keeps weather at 75% favorable for the Saturday launch window of NASA commercial cargo provider Northrop Grumman’s Antares rocket and Cygnus cargo spacecraft.
Northwesterly winds are expected Saturday morning into Saturday afternoon as an arctic area of high pressure builds into the Mid-Atlantic. Scattered low-level clouds, breezy winds, and cold temperatures are expected for Saturday, Feb. 20. The primary concerns for launch at this time are ground winds and a very slight chance of cumulus clouds and cloud ceilings.

Northrop Grumman is targeting 12:36 p.m. EST Saturday, Feb. 20, for the International Space Station-bound Cygnus, loaded with about 8,000 pounds of research, crew supplies, and hardware. Launch will be from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility near Chincoteague, Virginia.
Live coverage of the launch will air on NASA Television, the agency’s website and the NASA app beginning at 12 p.m. EST Saturday, Feb. 20, with a prelaunch event Friday, Feb. 19.
