DEEP IN Directed Energy Propulsion for Interstellar Exploration

We will examine a system that will allow us to take a significant step towards interstellar exploration using directed energy propulsion combined with wafer scale spacecraft. One of NASA's goals and one of humanity's grand challenges is to explore other planetary systems by remote sensing, sending probes, and eventually life to explore. This is a long standing and difficult to implement dream. The technological challenges are formidable. A step in this direction is to send small probes that will supplement the current long range remote sensing done by orbital telescopes.

As we outline in our papers the same basic system can be used for many purposes including both stand-on and stand-off planetary defense from virtually all threats with rapid response, orbital debris mitigation, orbital boosting from LEO to GEO for example, future ground to LEO laser assisted launchers, standoff composition analysis of distant object through molecular line absorption, active illumination of asteroids and other solar system bodies, beamed power to distant spacecraft among others. The same system can also be used for beaming power down to the Earth via micro or mm waves for selected applications. This technology will give us transformative options that are not possible now and allows us to go far beyond our existing chemical propulsion systems.

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
