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. It is designed for operation in low Earth orbit, serving as an atmospheric drag brake to facilitate the removal of satellite debris. [2]
The first successful solar sail spacecraft was the Japanese IKAROS mission, launched on 21 May 2010. [3] [4] [5]
The project is further developing technologies first tested on their STRaND-1 CubeSat, launched in February 2013. [6] 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. [7] [8]
CubeSail will be a three-axis stabilised solar sail satellite. [6] 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. [6] Attitude control can be enhanced by using the solar radiation pressure force on the sail to generate rotation torques. [9] The radiation pressure can also be used to induce a change of altitude as well as orbital inclination. [9]
The spacecraft will be deployed in a low Earth orbit (800 km altitude) on a Sun-synchronous orbit. [9]
The CubeSail nanosatellite is a CubeSat of the 3U format. [10] The satellite bus occupies approximately 1U, and the remaining 2U house the two-axis translation stage and sail-deployment subsystem. [10]
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. [6]
Solar sails are a method of spacecraft propulsion using radiation pressure exerted by sunlight on large surfaces. A number of spaceflight missions to test solar propulsion and navigation have been proposed since the 1980s. The first spacecraft to make use of the technology was IKAROS, launched in 2010.
A CubeSat is a class of small satellite with a form factor of 10 cm (3.9 in) cubes. CubeSats have a mass of no more than 2 kg (4.4 lb) per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are deployed into orbit from the International Space Station, or launched as secondary payloads on a launch vehicle. As of December 2023, more than 2,300 CubeSats have been launched.
The O/OREOS is a NASA automated CubeSat nanosatellite laboratory approximately the size of a loaf of bread that contains two separate astrobiology experiments on board. Developed by the Small Spacecraft Division at NASA Ames Research Center, the spacecraft was successfully launched as a secondary payload on STP-S26 led by the Space Test Program of the United States Air Force on a Minotaur IV launch vehicle from Kodiak Island, Alaska on 20 November 2010, at 01:25:00 UTC.
LightSail is a project to demonstrate controlled solar sailing within low Earth orbit using a CubeSat. The project was developed by The Planetary Society, a global non-profit organization devoted to space exploration. It consists of two spacecraft — LightSail 1 and LightSail 2. LightSail 1 was an engineering demonstration mission designed to test its new sail deployment method in space, it did not perform solar sailing. LightSail 2 was a fully functional spacecraft intended to demonstrate true solar sailing and incorporated the lessons learned from LightSail 1. LightSail is a follow-on project to Cosmos 1 — a solar-sail spacecraft designed by The Planetary Society in the early 2000s, which was destroyed during a launch failure in 2005.
IKAROS is a Japan Aerospace Exploration Agency (JAXA) experimental spacecraft. The spacecraft was launched on 20 May 2010, aboard an H-IIA rocket, together with the Akatsuki probe and four other small spacecraft. IKAROS is the first spacecraft to successfully demonstrate solar sail technology in interplanetary space. The craft's name is an allusion to the legendary Icarus, who flew close to the Sun on wings made of bird-feathers and wax.
Shin'en, known before launch as UNITEC-1 or UNISEC Technology Experiment Carrier 1, is a Japanese student spacecraft which was intended to make a flyby of Venus in order to study the effects of interplanetary spaceflight on spacecraft computers. In doing so, it was intended to become the first student-built spacecraft to operate beyond geocentric orbit. It was operated by UNISEC, a collaboration between several Japanese universities.
Waseda-SAT2 is a Japanese satellite which launched in May 2010. It is a student-built spacecraft, which will be operated by Waseda University, and is intended to be used for Earth observation and technology demonstration. It will test the use of extendible paddles to provide attitude control. The satellite is a single unit CubeSat.
NEE-01 Pegaso is an Ecuadorian technology demonstration satellite, and Ecuador's first satellite launched to space. Built by the Ecuadorian Civilian Space Agency (EXA), it is a nanosatellite of the single-unit CubeSat class. The spacecraft's instruments include a dual visible and infrared camera which allows the spacecraft to take pictures and transmit live video from space.
Technology Education Satellite (TechEdSat) is a successful nano-sat flight series conducted from the NASA Ames Research Center in collaboration with numerous universities. While one of the principal aims has been to introduce young professionals and university students to the practical realm of developing space flight hardware, considerable innovations have been introduced. In addition, this evolving flight platform has tested concepts for Low Earth Orbit (LEO) sample return, as well as planetary nano-sat class mission concepts.
STRaND-1 is a failed 3U CubeSat developed by Surrey University's Surrey Space Centre (SSC) and Surrey Satellite Technology (SSTL). The 4.3 kg (9.5 lb) nanosatellite was launched into orbit on board a PSLV Rocket from India on February 25, 2013, Smartphones have flown in space before inside the International Space Station, and the computer from a PDA launched inside two Japanese CubeSats in 2006 and 2008.
Space Tethered Autonomous Robotic Satellite II or STARS-II, was a nanosatellite built by Japan's Kagawa University to test an electrodynamic tether in low Earth orbit, a follow-on to the STARS mission.
ArgoMoon is a CubeSat that was launched into a heliocentric orbit on Artemis 1, the maiden flight of the Space Launch System, on 16 November 2022 at 06:47:44 UTC. The objective of the ArgoMoon spacecraft is to take detailed images of the Interim Cryogenic Propulsion Stage following Orion separation, an operation that will demonstrate the ability of a cubesat to conduct precise proximity maneuvers in deep space. ASI has not confirmed nor denied whether this took place, but several images of the Earth and the Moon were taken.
InflateSail was a 3U CubeSat launched on PSLV C38 on 23 June 2017 into a 505 km polar Sun-synchronous orbit. It carried a 1 m long inflatable rigidizable mast, and a 10 m2 drag-deorbiting sail. Its primary aim was to demonstrate the effectiveness of drag based deorbiting from low Earth orbit (LEO). Built by Surrey Space Centre of the University of Surrey, it was one of the Technology Demonstrator CubeSats for the QB50 mission. An identical drag sail payload was planned to be included on the RemoveDEBRIS demonstrator.
ASTERIA was a miniaturized space telescope technology demonstration and opportunistic science mission to conduct astrophysical measurements using a CubeSat. It was designed in collaboration between the Massachusetts Institute of Technology (MIT) and NASA's Jet Propulsion Laboratory. ASTERIA was the first JPL-built CubeSat to have been successfully operated in space. Originally envisioned as a project for training early career scientists and engineers, ASTERIA's technical goal was to achieve arcsecond-level line-of-sight pointing error and highly stable focal plane temperature control. These technologies are important for precision photometry, i.e., the measurement of stellar brightness over time. Precision photometry, in turn, provides a way to study stellar activity, transiting exoplanets, and other astrophysical phenomena.
