Seminar Abstract:

In January 2016, NASA selected SNC’s Dream Chaser Cargo System (DCCS) to provide cargo delivery, return, and disposal services for the International Space Station (ISS). Under the Commercial Resupply Services 2 (CRS2) contract, Dream Chaser will provide a minimum of six cargo service missions to and from the ISS between 2020 and 2024.

The DCCS is designed to deliver up to 5,500 kg of pressurized and unpressurized cargo to the ISS with the ability to conduct orbital disposal services and responsively return of pressurized cargo at less than 1.5 g’s to a gentle runway landing. The vehicle is designed for high reusability, reducing overall cost and providing rapid turnaround for re-flight opportunities, the ability to launch on top of multiple launch vehicles, and land at a wide variety of runways around the world. These capabilities make the Dream Chaser a flexible and viable option for reliable transportation to LEO while supporting a large variety of pressurized and unpressurized cargo and experiments.

Though the NASA CRS2 contract is the current customer, a team at SNC is looking beyond to other mission types Dream Chaser can support. Thursday’s presentation will have an overview of the DCCS along with additional capability to support alternative payloads and/or alternative missions. SNC is proud to have members of the technical team at the presentation to support LASP’s questions during the presentation and looking forward to discussing future possibilities with LASP.
