Overview

Destination: Low Earth Orbit
Mission: Mission Extension

Low Earth Orbit Kwajalein Atoll Air launch to orbit

Contracted by NASA under the Small Business Innovation Research Phase 3 contract, Katalyst Space Technologies' LINK servicing spacecraft will rendezvous and attach to NASA’s Neil Gehrels Swift Observatory to re-boost its orbit. This aims to demonstrate a key capability for the future of space exploration and extending the Swift mission’s science lifetime in gamma ray astronomy.

Pegasus XL

Family:
Configuration:

The Pegasus is an air-launched rocket developed by Orbital Sciences Corporation (now part of Northrop Grumman Innovation Systems). Capable of carrying small payloads of up to 443 kilograms (977 lb) into low Earth orbit, the vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 40,000 ft (12,000 m), and its first stage has a wing and a tail to provide lift and attitude control while in the atmosphere.
