CubeSail is a nanosatellite project by the Surrey Space Centre (SSC) in England. The spacecraft is a 3U CubeSat propelled by a solar sail. The CubeSail project is financed and technically supported by aerospace manufacturers Astrium and Surrey Satellite Technology. The first successful solar sail spacecraft was the Japanese IKAROS mission, launched on 21 May 2010.[2][3][4]

Overview

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.

Attitude control

CubeSail will be the first 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.[6] The radiation pressure can also be used to induce a change of altitude as well as orbital inclination.[6]

The spacecraft will be deployed in a low Earth orbit (800 km altitude) on a Sun-synchronous orbit.[6]

Configuration

The CubeSail nanosatellite is a CubeSat of the 3U format.[7] The satellite bus occupies approximately 1U, and the remaining 2U house the two-axis translation stage and sail-deployment subsystem.[7]

Objectives

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]
