solar array wing panels were folded against the orbital workshop
for launch, one on each side. When Skylab reached orbit, the arrays
would extend, exposing solar cells to the Sun to produce 12 kilowatts
of power. This array contains 147,840 solar cells.
the launch in May 1973, the micrometeoroid shield accidentally deployed
too soon, jamming one solar array wing and damaging the other so
badly that both the wing and the shield were torn loose from the
workshop. As a result, Skylab in space had only one solar array
wing, as seen in this exhibit.
clever engineering and improvisation, the effect of the damage was
minimized, and planned Skylab operations were completed despite
the reduction in power.
