K-1 (reusable space vehicle)
A two-stage, fully reusable aerospace vehicle designed to carry out a wide
range of missions, including payload delivery to low-earth
orbit (LEO), payload delivery to high-energy orbits with a K-1 Active
Dispenser, technology demonstration flights, microgravity
missions, and commercial cargo resupply, recovery, and reboost services
for the International Space Station. It is being
developed by Rocketplane Kistler,
a company which has recently won an award from NASA of more than $200 million
to help with work on the K-1, especially as it relates to the ISS.

The K-1 will be 121 feet (36.9 m) in overall length, 22 feet (6.7 m) in
diameter and weigh 841,000 pounds (382,300 kg) at liftoff. The vehicle,
powered by liquid-propellant engines supplied by Aerojet
Corporation, is designed to be reused 100 times.
Rocketplane Kistler plans to establish two launch sites for operating the
K-1, at Woomera, Australia, and Spaceport
Nevada. Test flights and initial commercial operations will be conducted
from Woomera. Spaceport Nevada is the second launch site and is located
at the Nevada Test Site, near Las Vegas.
