Skylab reached orbit but immediately suffered a critical setback: its micrometeoroid shield tore away during launch, taking a solar panel with it and jamming another, leaving the station overheating and underpowered. NASA scrambled to redesign a repair mission in just ten days. The first crew, launched eleven days later, successfully deployed a makeshift parasol sunshade and freed the jammed panel, saving the station.
Skylab was built from a repurposed Saturn V third stage, essentially a converted rocket hull turned into an orbital workshop nearly the size of a small house, with room for three astronauts to live and work for weeks at a time. Its launch was meant to showcase the fruits of the Apollo program's hardware repurposed for long-duration spaceflight research.
The near-disaster during ascent, when aerodynamic forces ripped away the station's protective micrometeoroid shield 63 seconds after liftoff, threatened to cook the station's interior and cripple its power supply. Engineers on the ground, working around the clock, devised an improvised gold-colored parasol sunshade that could be deployed through a small airlock.
When astronauts Pete Conrad, Paul Weitz, and Joseph Kerwin arrived on May 25, they performed a nail-biting spacewalk repair that effectively rescued the entire station, allowing it to host three crews and roughly 2,000 hours of scientific research over the following year, proving that humans could live and work in orbit for extended missions and paving the way for the International Space Station decades later.
