Draper Multi-Environment Navigator (DMEN) Hazard Detection Campaign

Completed TRL 6 (started at 4, targeting 6)

Description

The Draper Multi-Environment Navigator (DMEN)is a vision navigation system consisting of a suite of sensors, circuitry, a computer, and algorithms to process data into a navigation solution for rocket-powered landing systems. The system has successfully completed a high-altitude balloon campaign. This latest suborbital flight campaign plans to advance the instrument to higher altitudes faster velocity and simulated ground hazards under rocket-powered decent. 

Problem Statement 
While DMEN continues to show promise as a terrain-relative navigation instrument through Flight Opportunities campaigns, there is a second major function of DMEN that remains untested in flight: vision-based hazard detection. Draper has internally funded the creation of monocular vision, shadow-based hazard detection software compatible with the DMEN hardware. Although a camera-in-the-loop image simulator has been developed to test this software, flight data from a rocket-powered lander vehicle would greatly increase confidence in the software and the system TRL.

With this latest suborbital flight campaign, Draper is following on to the first two DMEN campaigns with rocket-powered lander vehicle testing. In addition to adapting the DMEN hardware to the intended flight vehicle, two flights will be planned to reach an altitude of approximately 500 meters and then execute a lunar-landing-like final approach, including flying over a simulated hazard field. 

Technology Maturation
DMEN has achieved high TRL (6-7) for both ground and low-altitude operations. The hazard detection technology is currently at TRL 4. This rocket-based flight campaign, including a hazard field, should allow for the collection of data and validation of algorithms in a relevant environment, advancing the system to TRL 5.

Benefits

As exploration reaches further into our solar system, crewed and robotic spacecraft will need to perform entry, descent,and landing (EDL) to complete their missions. The Draper Multi-Environment Navigator (DMEN) Hazard Detection Campaign aims to advance technology toward this goal. DMEN is a vision navigation system consisting of a suite of sensors, circuitry, a computer, and algorithms to process data into a navigation solution. The system has successfully completed a high-altitude balloon campaign. This latest suborbital flight campaign plans to advance the instrument to higher altitudes and faster velocity for continued testing.This would benefit NASA missions, the commercial space industry, and the nation.

How to get involved

This is early/mid-stage (TRL 6) — 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.
