A CubeSat is a type of space research picosatellite with dimensions of 10×10×10 centimetres (i.e., a volume of exactly one litre), weighing no more than one kilogram, and typically using commercial off-the-shelf electronics components.

Developed through joint efforts, California Polytechnic State University and Stanford University introduced the CubeSat to the world of academia as a means of opportunity for Universities throughout the world to enter into the realm of space science and exploration.

Currently, a large number of universities and some companies and other organizations around the world are actively developing CubeSats [1]. With their relatively small size, CubeSats can be made and launched for an estimated US$65,000–80,000 each (2004 US dollars). This low price tag, as compared to most satellite launches, has made Cubesat a viable option for schools and universities across the world. Most CubeSats carry one or two scientific instruments as their primary mission payload. A few CubeSat projects have a limited propulsion system; for example, the CubeSat project of the University of Illinois uses an array of small ion thrusters.

Launch history

2003

On 30 June 2003, five university CubeSats and one commercial CubeSat were launched on a Rockot rocket from Russia’s Plesetsk launch site. The launch was executed by Eurockot Launch Services GmbH of Bremen, Germany. The CubeSats on board were:

• Aalborg University's AAU CubeSat
• Quakefinder's Quakesat
• Technical University of Denmark's DTUsat
• Tokyo Institute of Technology's CUTE-I
• University of Tokyo's XI-IV
• University of Toronto's CanX-1

2005

On 27 October 2005, a Kosmos-3M launch vehicle launched from Plesetsk carried three CubeSats into orbit on the SSETI Express mission. The CubeSats on board were:

• Norwegian University of Science and Technology's NCUBE2
• University of Tokyo's XI-V
• University of Würzburg's UWE-1

2006

On 21 February, a M-V launch vehicle launched from Uchinoura, Japan carried a single CubeSat into orbit, namely:

• Tokyo Institute of Technology's CUTE-1.7

On July 26, 14 Cubesats from 11 universities, as well as a private company, were to be launched aboard a DNEPR Rocket, which failed and was destroyed during launch. California Polytechnic State University handled the details. This launch was postponed numerous times due to the primary payload, EgyptSat 1, not being ready. Due to ITAR concerns, the cubesats were moved to a different launch opportunity, with the primary payload from Belka. The launch was lost after the first stage engine shut down prematurely.. It is currently believed that all satellite parts were destroyed. The launch carried:

• ION by University of Illinois at Urbana Champaign, U.S.
• KUTESAT-1 by University of Kansas, U.S.
• NCUBE-1 by Norwegian University of Science and Technology, Norway
• Rincon 1 by University of Arizona, U.S.
• SACRED by University of Arizona, U.S.
• MEROPE by Montana State University, U.S.
• CP-1 by California Polytechnic State University
• CP-2 by California Polytechnic State University

2007

Seven Cubesats were launched April 17, 2007 as secondary payloads on a Dnepr rocket. They included:

• CSTB1 CubeSat TestBed 1 by Boeing -- Boeing Frontiers article Successful Mission Completion news release
• Libertad 1 by Universidad Sergio Arboleda, Colombia
• CAPE1 Cajun Advanced Picosatellite Experiment by University of Louisiana at Lafayette
• CP-3 by California Polytechnic State University
• CP-4 by California Polytechnic State University
• AeroCube 2 by The Aerospace Corporation
• Multi-Application Survivable Tether by Tethers Unlimited, Inc.

Future Launches

CanX-2[2], AAUsat-2, Compass-1[3], Delfi C3[4], CUTE-1.7+APD II[5] and 2nd SEEDS[6] are to be launched by Polar Satellite Launch Vehicle in 2007.[7]

A future launch is planned for 2008 which will include Auburn University's AubieSat-1. The launch date is undetermined.

There is also planned a launch in 2008 of the KY developed KySatI which was developed by multiple Kentucky universities.
