At SSDL, students had been working on the <a href="/w/index.php?title=OPAL_(Spacecraft)&action=edit&redlink=1" class="new" title="OPAL (Spacecraft) (page does not exist)">OPAL</a> (Orbiting Picosatellite Automatic Launcher) microsatellite since 1995. OPAL's mission to deploy daughter-ship "<a href="/wiki/Picosatellite" class="mw-redirect" title="Picosatellite">picosatellites</a>" had resulted in the development of a launcher system that was "hopelessly complicated" and could only be made to work "most of the time". With the project's delays mounting, Twiggs sought <a href="/wiki/DARPA" title="DARPA">DARPA</a> funding that resulted in the redesign of the launching mechanism into a simple pusher-plate concept with the satellites held in place by a spring-loaded door.<a href="#cite_note-Helvajian2008-10">[10]</a>: 151–157  Desiring to shorten the development cycle experienced on OPAL and inspired by the picosatellites OPAL carried, Twiggs set out to find "how much could you reduce the size and still have a practical satellite". The picosatellites on OPAL were 10.1 cm × 7.6 cm × 2.5 cm (4 in × 3 in × 1 in), a size that was not conducive to covering all sides of the spacecraft with solar cells. Inspired by a 4 in (10 cm) cubic plastic box used to display <a href="/wiki/Beanie_Babies" title="Beanie Babies">Beanie Babies</a> in stores,<a href="#cite_note-abio-6">[6]</a> Twiggs first settled on the larger ten-centimeter cube as a guideline for the new CubeSat concept. A model of a launcher was developed for the new satellite using the same pusher-plate concept that had been used in the modified OPAL launcher. Twiggs presented the idea to Puig-Suari in the summer of 1999 and then at the Japan–U.S. Science, Technology and Space Applications Program (JUSTSAP) conference in November 1999.<a href="#cite_note-Helvajian2008-10">[10]</a>: 157–159  The term "CubeSat" was coined to denote <a href="/wiki/Miniaturized_satellite#Nanosatellite" class="mw-redirect" title="Miniaturized satellite">nanosatellites</a> that adhere to the standards described in the CubeSat design specification. Cal Poly published the standard in an effort led by aerospace engineering professor Jordi Puig-Suari.<a href="#cite_note-tiny-12">[12]</a> <a href="/wiki/Bob_Twiggs" title="Bob Twiggs">Bob Twiggs</a>, of the Department of Aeronautics & Astronautics at Stanford University, and currently a member of the space science faculty at Morehead State University in Kentucky, has contributed to the CubeSat community.<a href="#cite_note-13">[13]</a> His efforts have focused on CubeSats from educational institutions.<a href="#cite_note-cnn-14">[14]</a> The specification does not apply to other cube-like nanosatellites such as the NASA "MEPSI" nanosatellite, which is slightly larger than a CubeSat. GeneSat-1 was NASA's first fully automated, self-contained biological spaceflight experiment on a satellite of its size. It was also the first U.S.-launched CubeSat. This work, led by John Hines at NASA Ames Research, became the catalyst for the entire NASA CubeSat program.<a href="#cite_note-15">[15]</a> In 2017, this standardization effort led to the publication of ISO 17770:2017 by the <a href="/wiki/International_Organization_for_Standardization" title="International Organization for Standardization">International Organization for Standardization</a>.<a href="#cite_note-16">[16]</a> This standard defines specifications for CubeSats including their physical, mechanical, electrical, and operational requirements.<a href="#cite_note-17">[17]</a> It also provides a specification for the interface between the CubeSat and its launch vehicle, which lists the capabilities required to survive the environmental conditions during and after launch and describes the standard deployment interface used to release the satellites. The development of standards shared by a large number of spacecraft contributes to a significant reduction in the development time and cost of CubeSat missions. <div class="mw-heading mw-heading2"><h2 id="Design">Design</h2>[<a href="/w/index.php?title=CubeSat&action=edit&section=2" title="Edit section: Design">edit</a>]</div> The CubeSat specification accomplishes several high-level goals. The main reason for miniaturizing satellites is to reduce the cost of deployment: they are often suitable for launch in multiples, using the excess capacity of larger launch vehicles. The CubeSat design specifically minimizes risk to the rest of the launch vehicle and payloads. Encapsulation of the launcher–<a href="/wiki/Payload_(air_and_space_craft)" class="mw-redirect" title="Payload (air and space craft)">payload</a> interface takes away the amount of work that would previously be required for mating a piggyback satellite with its launcher. Unification among payloads and launchers enables quick exchanges of payloads and utilization of launch opportunities on short notice. Standard CubeSats are made up of 10 cm × 10 cm × 11.35 cm (3.94 in × 3.94 in × 4.47 in) units designed to provide 10 cm × 10 cm × 10 cm (3.9 in × 3.9 in × 3.9 in) or 1 L (0.22 imp gal; 0.26 US gal) of useful volume, with each unit weighing no more than 2 kg (4.4 lb).<a href="#cite_note-:6-2">[2]</a> The smallest standard size is 1U, consisting of a single unit, while the most common form factor was the 3U, which comprised over 40% of all nanosatellites launched to date.<a href="#cite_note-18">[18]</a><a href="#cite_note-specs-19">[19]</a> Larger form factors, such as the 6U and 12U, are composed of 3Us stacked side by side.<a href="#cite_note-:6-2">[2]</a> In 2014, two 6U <a href="/wiki/Perseus-M" title="Perseus-M">Perseus-M</a> CubeSats were launched for maritime surveillance, the largest yet at the time.

Most COTS and custom designed electronics fit the form of <a href="/wiki/PC/104" title="PC/104">PC/104</a>, which was not designed for CubeSats but presents a 90 mm × 96 mm (3.5 in × 3.8 in) profile that allows most of the spacecraft's volume to be occupied.

Stackthrough connectors on the boards allow for simple assembly and electrical interfacing and most manufacturers of CubeSat electronics hardware hold to the same signal arrangement, but some products do not, so care must be taken to ensure consistent signal and power arrangements to prevent damage.<a href="#cite_note-27">[27]</a> Care must be taken in electronics selection to ensure the devices can tolerate the radiation present. For very <a href="/wiki/Low_Earth_orbit" title="Low Earth orbit">low Earth orbits</a> (LEO) in which atmospheric reentry would occur in just days or weeks, <a href="/wiki/Radiation" title="Radiation">radiation</a> can largely be ignored and standard consumer grade electronics may be used.

Aluminum used on the structure which contacts the P-POD must be <a href="/wiki/Anodize" class="mw-redirect" title="Anodize">anodized</a> to prevent <a href="/wiki/Cold_welding" title="Cold welding">cold welding</a>, and other materials may be used for the structure if a waiver is obtained.<a href="#cite_note-specs-19">[19]</a> Beyond cold welding, further consideration is put into material selection as not all materials can be <a href="/wiki/Materials_for_use_in_vacuum" title="Materials for use in vacuum">used in vacuums</a>. Structures often feature soft dampers at each end, typically made of rubber, to lessen the effects of impacting other CubeSats in the P-POD. Protrusions beyond the maximum dimensions are allowed by the standard specification, to a maximum of 6.5 mm (0.26 in) beyond each side. Any protrusions may not interfere with the deployment rails and are typically occupied by antennas and solar panels. In Revision 13 of the CubeSat Design Specification an extra available volume was defined for use on 3U projects. The additional volume is made possible by space typically wasted in the P-POD Mk III's spring mechanism. 3U CubeSats which utilize the space are designated 3U+ and may place components in a cylindrical volume centered on one end of the CubeSat. The cylindrical space has a maximum diameter of 6.4 cm (2.5 in) and a height no greater than 3.6 cm (1.4 in) while not allowing for any increase in mass beyond the 3U's maximum of 4 kg (8.8 lb). Propulsion systems and antennas are the most common components that might require the additional volume, though the payload sometimes extends into this volume.

This may be due to limitations in the primary computer's ability to control the payload with limited communication protocols, to prevent overloading the primary computer with raw data handling, or to ensure payload's operation continues uninterrupted by the spacecraft's other computing needs such as communication.

Combinations of these systems are typically seen in order to take each method's advantages and mitigate their shortcomings. <a href="/wiki/Reaction_wheels" class="mw-redirect" title="Reaction wheels">Reaction wheels</a> are commonly utilized for their ability to impart relatively large <a href="/wiki/Moment_(physics)" title="Moment (physics)">moments</a> for any given energy input, but reaction wheel's utility is limited due to saturation, the point at which a wheel cannot spin faster. Examples of CubeSat reaction wheels include the Maryland Aerospace MAI-101<a href="#cite_note-34">[34]</a> and the Sinclair Interplanetary RW-0.03-4.<a href="#cite_note-35">[35]</a> Reaction wheels can be desaturated with the use of thrusters or magnetorquers. Thrusters can provide large moments by imparting a <a href="/wiki/Couple_(mechanics)" title="Couple (mechanics)">couple</a> on the spacecraft but inefficiencies in small propulsion systems cause thrusters to run out of fuel rapidly. Commonly found on nearly all CubeSats are magnetorquers which run electricity through a coil to take advantage of Earth's magnetic field to produce a <a href="/wiki/Moment_(physics)" title="Moment (physics)">turning moment</a>. Attitude-control modules and solar panels typically feature built-in magnetorquers. For CubeSats that only need to detumble, no attitude determination method beyond an <a href="/wiki/Angular_rate_sensor" title="Angular rate sensor">angular rate sensor</a> or electronic <a href="/wiki/Gyroscope" title="Gyroscope">gyroscope</a> is necessary. Pointing in a specific direction is necessary for Earth observation, orbital maneuvers, maximizing solar power, and some scientific instruments. Directional pointing accuracy can be achieved by sensing Earth and its horizon, the Sun, or specific stars. Sinclair Interplanetary's SS-411 Sun sensor<a href="#cite_note-36">[36]</a> and ST-16 star tracker<a href="#cite_note-37">[37]</a> both have applications for CubeSats and have flight heritage.

The mission CubeSat technology is called <a href="/wiki/Mars_Cube_One" title="Mars Cube One">Mars Cube One</a> (MarCO); each one is a six-unit CubeSat, 14.4 in × 9.5 in × 4.6 in (37 cm × 24 cm × 12 cm). MarCO is an experiment, but not necessary for the InSight mission, to add relay communications to space missions in important time durations, in this case from the time of InSight atmospheric entry to its landing. MarCO launched in May 2018 with the InSight lander, separated after launch and then traveled in their own trajectories to Mars. After separation, both MarCO spacecraft deployed two radio antennas and two solar panels. The high-gain, <a href="/wiki/X_band" title="X band">X band</a> antenna is a flat panel to direct radio waves. MarCO navigated to Mars independently from the InSight lander, making their own course adjustments on the flight.
