PROX 1

NSSDCA/COSPAR ID: 2019-036A

Description

The Prox 1 mission was designed to demonstrate automated trajectory control in low-Earth orbit relative to a deployed cubesat, but was later downscoped to just deploy LightSail B and provide an optical .

The spacecraft has been designed, fabricated and tested by a team of Georgia Tech undergraduate and graduate students who will also be resposible for missions operations. The Prox-1 spacecraft is equipped with thermal and visible imagers provided by Arizona State University. Prox-1 will deploy a smaller spacecraft called LightSail B, a 3U CubeSat solar sail demonstration mission developed by The Planetary Society in partnership with Stellar Exploration, Inc. and Cal Poly.

Prox-1 was to fly in close proximity to the LightSail spacecraft, demonstrating automated trajectory control based upon relative orbit determination using passive imaging. Prox-1 was also to acquire images of the LightSail solar sail deployment event, and was to provide first-time flight validation of advanced sun sensor technology, a small satellite propulsion system, and a lightweight thermal imager.
