Lunar Assay via Small Satellite Orbiter (LASSO)

Background
The LASSO program, initiated by DARPA, aims to enhance the United States' capabilities in space situational awareness through the development of technologies for autonomous satellite navigation and increased satellite maneuverability.

The program focuses on creating a spacecraft that can identify areas on the Moon with over 5% water concentration, facilitating resource utilization for in-situ resource utilization (ISRU) on the lunar surface. The mission is designed to operate in lunar orbit without deploying equipment on the lunar surface itself.

Work Details
The contract involves multiple phases:
- Phase 1A focuses on concept design, including defining scientific objectives and technical approaches;
- Phase 1B involves refining designs and subsystem specifications;
- Phase 2 is dedicated to building and launching the spacecraft.

Key tasks include:
- Developing a spacecraft capable of autonomous navigation in low lunar orbit (LLO).
- Designing a prospecting sensor to detect water concentration remotely.
- Balancing altitude for high-resolution measurements with energy requirements for prolonged orbital data capture.
- Conducting economic viability analyses of proposed ISRU approaches without government input.
- Performing detailed subsystem analysis including propulsion, communication, power, and thermal management systems.
- Validating designs through simulations and testing, including Software In The Loop (SWIL) testing for high-risk technologies.
- Delivering a final spacecraft ready for integration with NASA for launch.

Period of Performance
The overall program is structured into three phases: Phase 1A lasting approximately 6 months, Phase 1B lasting about 18 months, and Phase 2 anticipated to take around 12 months.

Place of Performance
The work will primarily be conducted at contractor facilities with potential collaboration involving NASA and USGS personnel.
