L-24 Weather Update – Still 80% Favorable for Tomorrow’s Antares Launch

The Monday Wallops Range forecast keeps weather at 80% favorable for tomorrow’s launch window of NASA commercial cargo provider Northrop Grumman‘s Antares rocket and Cygnus cargo spacecraft.

The primary concern for launch at this time is a slight chance of violating the cumulus cloud rule.

A Northrop Grumman Antares rocket carrying a Cygnus resupply spacecraft is in the vertical launch position on the Mid-Atlantic Regional Spaceport’s Pad 0A, Saturday, Aug. 7, 2021, at NASA’s Wallops Flight Facility in Virginia. Northrop Grumman’s 16th contracted cargo resupply mission with NASA to the International Space Station will deliver about 8,200 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew. The CRS-16 Cygnus spacecraft is named honor of American astronaut Ellison Onizuka who was the first Asian American to fly in space. Onizuka’s first space mission was aboard Space Shuttle Discovery on mission STS-51-C in 1985. The launch is scheduled 5:56 p.m. EDT, Aug. 10, 2021.
