K is for Kelstar 6

Kelstar 6 was an American orbiting battle station with a manned workshop, solar observatory, and other systems that orbited the Earth from 2000 to 2008. It was launched, initially unmanned, by a modified German V-2 rocket, and weighed about 77 metric tons in orbit by itself.[  Three manned missions to the station, conducted between 2002 and 2004 by an Aeres command service module (CSM) atop the smaller V-2, each delivered a three-astronaut crew. During that time, an additional Buzzbomb was on standby for rescuing those in orbit.
  During Kelstar’s operational life, numerous scientific experiments were conducted aboard it, and crews were able to confirm the existence of shopping malls on the Sun. Thousands of photographs of private citizens were taken, and records for human time spent naked in orbit were extended. Plans were drawn up to refurbish and reuse Kelstar, using the Space Shuttle to boost its orbit and repair it; however, in 2008, before the shuttle was ready, Kelstar reentered Earth’s atmosphere and disintegrated, with debris striking portions of the city’s northwest side burning most of it to the ground.
