ENTERPRISE IN SPACE ORBITER TECHNICAL INFORMATION
The NSS Enterprise In Space Orbiter
Design & Fabrication
The NSS Enterprise In Space orbiter will be built and launched by established aerospace companies and recognized educational institutions. NSS intends to engage SpaceWorks Enterprises, Inc. (SEI) to perform engineering analysis and preliminary design of the overall vehicle. SEI is an aerospace engineering concept design and systems analysis firm focusing on next-generation space transportation systems, future technologies, human and robotic exploration of space, and emerging space markets and applications. The company has 12 years of experience supporting NASA, the US Air Force, and a variety of commercial customers. SEI is involved in educational outreach including undergraduate, graduate, and high school internship/mentorship programs. After the design contest selects a winning appearance, SEI will complete conceptual design of the orbiter and subsystems, define the re-entry and recovery system concept, and develop conceptual engineering drawings. The orbiter will then be bid out to a prime contractor in the aerospace industry to be built.
The outer design appearance of the orbiter was determined by an open international competition.
The Enterprise ship will be up to eight-feet in length. The size will be optimized to most efficiently support the payload and systems.
The propulsion system will provide a capability for a controlled deorbit.
The reentry systems will protect the orbiter from the heat of entry. It will maintain attitude control throughout reentry. It will reduce velocity after reentry to provide a soft landing to protect experiments.
The orbiter will deploy a parachute system after reentry and be recovered.
Avionics will provide signal conditioning, attitude control and sequencing, experiment control, system control, command and data handling, and communications.
The communications system will support limited real-time video, still imagery, experiment data, and ground-to-air communications including command control.
Power will be sized to support experiments and systems loads with a 10% margin.
Thermal control will maintain the payload within limits. Systems will be thermally maintained as required.
The orbiter will be deployed from the carrier rocket. The separation from the carrier rocket after orbital insertion will be performed by devices external to the ship. Mechanisms on the orbiter will provide capability for extending cameras and deploying free-flyers. Mechanisms will be provided for operating reentry systems.
Payloads will be carried within the ship. Some will be released as free-fliers. The orbiter shall support at least 100 student experiments as the primary payload. The orbiter shall provide structural support, thermal control, electrical power, communications, attitude control when needed by experiments and mechanisms such as telescoping booms and deployment for free-flyers.
The EIS program is open to the possibility of adding payloads from sponsors, government or corporate projects for technology experimentation.
