Sensor Test for Orion Relative navigation Risk Mitigation (STORRM)
This new docking navigation system prototype consists of an eye-safe lidar Vision Navigation Sensor, or VNS, a high-definition docking camera, as well as the avionics and flight software. Both sensors will provide real-time three-dimensional images to the crew with a resolution 16 times higher than the current space shuttle sensors. This next generation system also provides data from as far away as three miles – three times the range of the current shuttle navigation sensor.
The hardware will be tested by astronauts aboard STS-134, the last planned shuttle mission, currently scheduled for April 2011, as part of the STORRM Development Test Objective (DTO). On Flight Day 11 of the mission, the shuttle crew will conduct an unprecedented on-orbit maneuver; they will undock from the space station and then re-rendezvous with the station on an Orion-like approach.
