Cranfield De-Orbiting Sail Products

Space debris mitigation policies are increasingly being mandated in order to limit or reduce the growth of the debris population in Earth orbit with the ESA Clean Space initiative establishing Space Debris Mitigation requirements.  The Inter-Agency Space Debris Coordination Committee (IADC) mitigation guidelines express the removal of space systems within the Low Earth Orbit (LEO) region be de-orbited not later than 25 years after the End of Mission.  Cranfield Aerospace Solutions Limited (CAeS) declare the availability of the Cranfield Drag Augmentation System (DAS).

The DAS is an atmospheric drag augmentation system that deploys a De-Orbiting sail (or film Aerobrake) from LEO satellites to increase drag to more rapidly de-orbit the satellite. Developed by the Cranfield University Space Research Group, the DAS is already in Earth orbit: Icarus-1 was launched on SSTL TechDemoSat-1 (TDS-1) on 8 July 2014 and Icarus-3 was launched on SSTL Carbonite-1 on 10 July 2015. Both are still on mission.

A smaller compact DAS named DOM (De-Orbiting Mechanism) is currently scheduled for launch late 2017 aboard the European Space Agency (ESA) European Student Earth Orbiter (ESEO).  All De-Orbiting Devices are configured to match each small or micro-satellite’s specific criteria (1000kg satellite, ~800km orbit) to allow expected de-orbit in

  • Low-cost
  • Simple (both design and interfaces to satellite)
  • Safe
  • Reliable
  • Mass ≤ propellant mass to deorbit
  • Minimal impact on host satellite
  • Easily testable in 1-g
  • No additional debris production
  • Tolerates some failures/degradation of host satellite
