Scientists at the University of Surrey, working on the project funded by the European space company Astrium, have devised a 3 kg miniature satellite or "nanosatellite" fitted with a "solar sail"."CubeSail" is a device which can be fitted to satellites or launch vehicle upper stages that are sent into orbit and then can be deployed to successfully de-orbit equipment that has reached the end of its mission.
A 5 x 5 m, 3 kg, deployable sail is being developed to fit in a 10 x 10 x 30 cm nanosatellite and will be used in a demonstration mission to be launched in late 2011 demonstrating passive means of deorbiting for future satellites.
Dr Vaios Lappas, lead researcher on the project and Senior Lecturer in Space Vehicle Control at the Surrey Space Centre, said: "Protecting our planet and environment is key for sustainable growth. CubeSail is a novel, low cost space mission which will demonstrate for the first time space debris/satellite deorbiting using an ultra light 5 x 5 sail stowed and supported on a 3 kg nanosatellite.
“Successful deployment and testing of the sail can enable a low cost/mass solution to be used for future satellites and launch vehicle upper stages reducing dramatically the problem of space debris.
"Following successful in orbit demonstration, the proposed deorbit system will be offered as a standard deorbit system for Low Earth Orbit missions for satellites with a mass of less than 500 kg at a very low cost."
