Virginia's First Satellite Launch – 50 Years Ago Today

50 Years Ago Today: The First Spacecraft Launched Into Orbit From Virginia
“Explorer 9 was the first spacecraft placed in orbit by an all-solid rocket and the first spacecraft successfully launched from Wallops Island. It was launched on 16 February 1961. Explorer 9 was the first in a series of 3.66 m inflatable spheres to be successfully placed into orbit solely for the determination of atmospheric densities. It was identical in its objectives and configuration to the earlier unsuccessful launch of Explorer S-56.”
Keith’s 15 Feb note: Thanks to a tip by @NASAHistory. Too bad Wallops PAO is not aware of this anniversary.
