Quick Facts

About the Project:

Lisa Concept
LISA mission concept.

Space Technology 7 (ST7) will flight test the Disturbance Reduction System (DRS), system-level technology designed to demonstrate trajectory control and formation-flying spacecraft position control. DRS will feed into future missions, such as the joint European Space Agency and NASA Laser Interferometer Space Antenna (LISA) mission.

About the Technology:

The ST7 DRS consists of clusters of micronewton thrusters and controlling software residing on a dedicated computer. In concept with the European Space Agency's LISA Technology Package Inertial Sensor, DRS is based on the concept of a freely floating mass, shielded from nongravitational forces, onboard a host spacecraft.
