Specs for the Rockwell STS

Gemini Sparkle

Key Takeaways:

  • The vehicle is a high-performance orbital spacecraft, capable of reaching altitudes up to 643 km and speeds of nearly 28,000 kph (17,321 mph), with an astonishing ascent rate of 132,000 fpm.
  • It operates with a vertical launch (indicated by 0 ft takeoff distance) involving Solid Rocket Booster and External Tank separation within minutes, but lands horizontally like a glider, requiring a significant runway ground roll of 7,000 to 10,000 feet.
  • Massive at liftoff (4.5 million pounds), the system dramatically lightens for touchdown (230,000 pounds) and is designed to transport a maximum cargo of 28,803 kg (63,500 pounds) to orbit.
