United States Air Force GRS Scout X-4
About the GRS Mission
- Type: Earth Science
- Orbit: Low Earth Orbit
GRS (Geophysical Research Satellite) was a geophysics experiment test built by the Cambridge Research Lab (CRL). Data was obtained for 13 orbits, after which time the satellite ceased working due to a failure in the primary power supply.
Launch Pad & Location
Launch Area 3
Wallops Flight Facility, Virginia, USA
The Launch Area 3 launch pad has hosted 13 rocket launches, including 10 orbital launch attempts. The Wallops Flight Facility, Virginia, USA launch site has been the location for 84 total rocket launches.
Wallops Flight Facility is a rocket launch site on Wallops Island on the Eastern Shore of Virginia, United States, just east of the Delmarva Peninsula and north-northeast of Norfolk. The facility is operated by the Goddard Space Flight Center in Greenbelt, Maryland, and primarily serves to support science and exploration missions for NASA and other federal agencies. WFF includes an extensively instrumented range to support launches of more than a dozen types of sounding rockets; small expendable suborbital and orbital rockets; high-altitude balloon flights carrying scientific instruments for atmospheric and astronomical research; and, using its Research Airport, flight tests of aeronautical research aircraft, including uncrewed aerial vehicles.
Vought Scout X-4 Rocket
The Scout family of rockets were were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages.
