The Shuttlee, and launched by NASA on a Delta on 10 July 1962. Although the satellite relayed the first television across the Atlantic, large swivelling antennas were required to communicate with it and the 6,000-kilometre apogee restricted its use as a long-distance relay to brief periods.

Back to expendablesatellite. Unfortunately, at T + 8 seconds it exploded at an altitude of 800 feet. The fragmental debris and burning propellant caused severe damage to SLC-4E and the nearby facilities. The explosion also created a toxic cloud that rose to an altitude of 8,000 feet before being blown out to sea.. Eac

Heavyweights advertised flight rate, and that without considerable further development it would not meet its target of being able to insert a 14.5-tonne payload into polar orbit.

Failure and redundancy imminent failure, but not always. In this book, we generally restrict our attention to cases where something actually goes seriously wrong. Not all failures are fatal to the spacecraft,. and, in fact, the most impressive feats of space systems engineering tend to be those that overcome failures. Im
