The unmanned spacecraft will provide cargo – such as food, water and scientific instruments – to the International Space Station (ISS) under NASA’s Commercial Resupply Services 2 (CRS2) program. Jena-Optronik’s RVS3000 rendezvous and docking sensor will support the autonomous approach of the Dream Chaser to the ISS making it the fourth ISS supply spacecraft to use the sensor technology from Jena. The selection follows consultations between Sierra Nevada Corporation and Jena-Optronik which started thanks to the DLR sponsored US-German Aerospace Roundtables (UGART).

“RVS3000 sensors on Dream Chaser will lead us to new technical dimensions”, explains Dr. Florian Kolb, Director Lidar Products at Jena-Optronik. “For the first time a cargo spacecraft will be reused. This is a premier in space. Reusing our technology, including handling by astronauts, is also an exciting premier for us that warranted to go the extra mile to support our customer.”

With the program and its contribution, Jena-Optronik enters the market of in-orbit multiuse missions. Each Dream Chaser will have two RVS3000 sensors on board, which will be dismounted by an astronaut and stowed within the spacecraft before the undocking.

“In the literal sense: chasing the dream of travelling in space.  The sensor solution selected by SNC will have the capability to approach other targets besides the ISS – a crucial capability to set up an infrastructure in orbit or to support demanding robotic tasks. We are proud to be  part of these new spectacular missions!”, illustrates Dietmar Ratzsch, President & CEO Jena-Optronik.
About Dream Chaser Spacecraft

Owned and operated by SNC, the Dream Chaser spacecraft is a reusable, multi-mission space utility vehicle (SUV). It is capable of transportation services to and from low-Earth orbit, where the International Space Station (ISS) resides, and is the only commercial, lifting-body vehicle capable of a runway landing. The Dream Chaser Cargo System was selected by NASA to provide cargo delivery and disposal services to the ISS under the Commercial Resupply Services 2 (CRS2) contract. All Dream Chaser CRS2 cargo missions are planned to land at Kennedy Space Center’s Shuttle Landing Facility.
