Product Description

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
  • Efficient, highly scalable packaging
  • Mass < 2.8 kg
  • Frangibolt® actuated release
  • High margin, robust and reliable spring-powered deployment
  • Shaped, deployed membrane to support vehicle passive stability
  • Optional Standoff Mechanism and De-orbit Power Electronics
