Time to Hit Warp Speed, Galileo

April 23, 2013By

Report from ENC: Constellation Needs 22 Satellites in Three Years Launch, deploy, and operate “22 satellites in less than 3 years.” That’s two satellites every three months, leading to a four-at-once launch in 2014. And that’s the challenge that Europe and the European Space Agency (ESA) now face. This pointed call to action during the opening plenary of the European... read more
