“NASA to launch secretive US military payloads on 3 sounding rockets from Virginia tonight”
By Rahul Rao 20 October 2021
The flights are for the military, so details are scant.
NASA will launch three sounding rockets from coastal Virginia on flights that local observers may be able to spot in the sky.
Details about the launches are scarce, as the rockets are carrying payloads from the U.S. Department of Defense. But the three rockets will take off from NASA's Wallops Flight Facility on Wednesday (Oct. 20) between 5 and 11 p.m. EDT (2100 GMT to Oct. 21 at 0300 GMT). Should foul weather scuttle the flights, NASA has slated Thursday (Oct. 21) and Friday (Oct. 22) as backup launch dates.
"The Department of Defense utilizes launch pads at the Wallops Flight Facility for environmentally relevant flight testing of system components. We do not provide dates, times or details in advance," a spokesperson for the Department of Defense told Space.com in an email.
