Summary
CubeSail is a proposed nanosatellite project by the Surrey Space Centre (SSC) in England. The spacecraft is to be a 3U CubeSat propelled by a 25 m² solar sail. The project is financed and technically supported by aerospace manufacturers Astrium and Surrey Satellite Technology.

Overview edit
The project is further developing technologies first tested on their STRaND-1 CubeSat, launched in February 2013.[5] CubeSail will deploy a 25 m2 solar sail, which will be used to demonstrate the propulsive effect of solar radiation pressure and the de-orbiting capabilities of the sail as a drag augmentation device.[6][7]
Attitude control edit
CubeSail will be a three-axis stabilised solar sail satellite.[5] Attitude control (orientation) is necessary because the orientation of the sail relative to the Sun direction will determine the propulsion force. Full three-axis attitude control will be performed by means of a centre of mass/centre of pressure offset technique, complemented by three magnetorquers and a reaction wheel.[5] Attitude control can be enhanced by using the solar radiation pressure force on the sail to generate rotation torques.[8] The radiation pressure can also be used to induce a change of altitude as well as orbital inclination.[8]
The spacecraft will be deployed in a low Earth orbit (800 km altitude) on a Sun-synchronous orbit.[8]
Configuration edit
The CubeSail nanosatellite is a CubeSat of the 3U format.[9] The satellite bus occupies approximately 1U, and the remaining 2U house the two-axis translation stage and sail-deployment subsystem.[9]
Objectives edit
The objectives of the CubeSail mission are to demonstrate the concept of solar sail propulsion of a 3-axis stabilised 25 m2 solar sail for one year while in low Earth orbit; and to demonstrate the use of gossamer structures (very light gauze-like fabric) as a drag augmentation device for satellite de-orbiting.[5]
