CLEANING UP SPACE, ONE SATELLITE AT A TIME
MMA’s dragNET™ De-Orbit system consists of a lightweight, compact-stowed, thin membrane that releases via a simple heater power circuit. Deployment of the de-orbit membrane is powered by the release of spring energy and, once tensioned, creates the necessary drag to passively de-orbit the spacecraft or launch vehicle. dragNET™ leaves valuable space propulsion resources for extension mission life, weighs only 2.8 kilograms, and will achieve de-orbit of a 180 kg (400 lb) ESPA-class spacecraft from altitudes of <850 kilometers in less than 10 years.
dragNET™ has been flight qualified to meet DoD and NASA requirements for de-orbiting satellites in low earth orbit 9=(LEO), and has successfully de-orbited the ORS-3 Minotaur I Upper Stage within a 2-year time frame.
Key product characteristics are:
- An elegant bolt-on solution that minimizes impact to integration and operations
- De-orbit < 25 years from 850 km
- 14 m2 of effective aerodrag deployed area
