Through targeted development and frequent in space testing, the program:

  • Enables execution of missions at much lower cost than previously possible.

  • Substantially reduces the time required for development of spacecraft.
  • Enables new mission architectures through the use of small spacecraft.

  • Expands the reach of small spacecraft to new destinations and challenging new environments.

  • Enables the augmentation of existing assets and future missions with supporting small spacecraft.

The program achieves its objectives through:

  • Identification and investment in the development of new subsystem technologies to enhance or expand the capabilities of small spacecraft.

  • Sponsorship of flight demonstrations of new technologies, capabilities and applications for small spacecraft.

  • Promotion of the use of small spacecraft as platforms for testing and demonstrating technologies and capabilities that might have more general applications in larger-scale spacecraft and systems.  

Program-funded projects may be executed at academic institutions, in the private sector, at NASA centers, as public-private partnerships, or cooperative agreements.
