Skylab was launched 14 May 1973 by a Saturn V (the last launch of such a rocket) with the upper stage removed, but with the avionics remaining in the same position (different from the Saturn INT-21 rocket, which could launch payloads not based on the S-IVB) into a 235-nautical-mile (435-km) orbit. The launch is sometimes referred to as Skylab 1, or SL-1. Severe damage was sustained during launch and deployment, including the loss of the station's micrometeoroid shield/sun shade and one of its main solar panels. Debris from the lost micrometeoroid shield further complicated matters by pinning the remaining solar panel to the side of the station, preventing its deployment and thus leaving the station with a huge power deficit.
