Small Satellites Timeline

  • 1869-1879 First Fictional Artificial Satellites

    The first fictional depictions of satellites being launched into orbit are published in Edward Everett Hale’s short story The Brick Moon (1869) and Jules Verne’s The Begum’s Fortune (1879).

  • 1934 Communications Act

    Passed long before the first spaceflight, the Communications Act has been amended over time to govern requirements for commercial satellite operations, licensing, and coordination in the use of the radio spectrum.

  • 1945 Satellite Communications System Proposed

    British science fiction writer and inventor Arthur C Clarke (1917-2008) publishes an article that shows how geostationary satellites could be used for worldwide radio and television broadcasts and communication.

  • 1957 Start of the First Space Age

    The space age began on October 4, 1957 with the Soviet launch of Sputnik 1, the first human-made object to orbit the Earth. This event surprised many in the United States and raised fears that the Soviet Union was pulling ahead in missile technology. It ignited a frenetic competition for superiority in space. In pursuit of that superiority, both countries made significant investments in order to attain rapid technological advances in rockets, satellites, and human spaceflight. Because of these advances, the United States and Soviet Union quickly became the dominant powers in space.

    From 1957 through 1990, the United States and Soviet Union were responsible for 93 percent of all satellites launched into space.

    Soviet Union’s first (small) satellite 82 kg

  • 1958 Explorer 1

    United States’ first (small) satellite 14 kg

  • 1958 National Aeronautics & Space Act

    The act established NASA as well as U.S. objectives in space: expanding space knowledge; creating and improving space vehicles; studies of benefits from space operation; preserving the United States as a space leader; and sharing discoveries with defense agencies.

  • 1960 Smallsats as Pathfinders

    A large number of small satellites were launched throughout the 1960’s to obtain space environment data, flight test various technologies, and provide operational communications.

  • 1962 Start of the Commercial Space Age

    The first commercial use of satellites was the Telstar 1 (small) satellite which was launched in 1962. The satellite and launch were paid for by AT&T and Bell Telephone Laboratories. Telstar 1 was capable of relaying television signals across the Atlantic Ocean, and was the first satellite to transmit live television, telephone, fax, and other data signals.

  • 1971 Intel 4004 Microprocessor

    The World’s first commercially produced microprocessor.

  • 1972 Beginning of Landsat Program

    The Earth Resources Technology Satellite is launched. This beqins the longest-running programme of satellite imagery of the Earth, later renamed Landsat. Landsat instruments acquire millions of images that are used to evaluate natural and human changes to the Earth.

  • 1977 Start Of Small Satellite Doldrums

    Satellites grew heavier over time as satellite functionality expectations and launch vehicle payload capacity to low Earth orbit increased. Microsatellites, nanosatellites, and picosatellites were replaced by heaver, much more capable, spacecraft over time. This trend resulted in the “Small Satellite Doldrums” that started in approximately 1977 and lasted 10 years. During that period of time, very few microsatellites were launched and no nano or pico satellites were launched.

  • 1978 Kessler Syndrome

    The “Kessler syndrome” (also called the ”’Kessler effect”, “collisional cascading”, or “ablation cascade”), proposed by NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit due to space pollution is high enough that collisions between objects could cause a cascade in which each collision generates space debris that increases the likelihood of further collisions.

  • 1984 The Commercial Space Launch Act

    The law grants the U.S. Department of Transportation regulatory oversight of commercial space flight, it indemnifies companies for large third-party damages and it establishes regulations for commercial human space flight.

  • 1984 Land Remote-Sensing Commercialization Act

    The law is primarily concerned with transferring the U.S. government-owned Landsat satellite program to private industry, allowing companies to take over operation of the Earth-imaging satellite constellation.

  • 1987 End of Small Satellite Doldrums

    Technology and economics reversed the trend towards larger satellites starting in 1987. Technology advances increased the scope of functionalities possible using small satellites, e.g. microprocessors, solar cells, batteries, microelectronics, software, and the Internet.

  • 1990 Start of Secondary Payloads Market

    On Jan. 21, 1990, an Ariane-4 put the French SPOT-2 Earth resources satellite into orbit, along with six microsatellites. This was the first flight of the Ariane Structure for Auxiliary Payload (ASAP) ring that could hold up to six small satellites with a maximum mass of 50-kg each and maximum dimensions of 35 x 35 x 60-cm. The maximum mass that could be put onto the ASAP was 200 kg.

    Microsatellites and nanosatellites now had a standard, commercial, launch service that could put 6 satellites at a time into orbit.

  • 1991 Start of the Second Space Age

    As the cold war came to an end in 1991, the space domain began to transition into what has been called the “second space age.” This transition was the result of nearly simultaneous shifts in the commercial uses of space, the geopolitical environment on Earth, and the military balance of power. The fall of the Soviet Union meant that there were no longer two superpowers locked in a stable, long-term competition in space.

    Beginning in the 1990s space capabilities began to spread to other countries and commercial firms.

  • 1992 Land Remote-Sensing Policy Act

    This law repealed the Land Remote-Sensing Commercialization Act, as transfer to the private sector of the U.S. government-owned Landsat proved problematic. The new law gave the Department of Commerce the power to license and regulate a U.S. commercial remote-sensing industry and to outsource the development of new Landsat components to the private sector.

  • 1994 First GPS Constellation

    The first global positioning system constellation becomes operational. It consists of 24 geosynchronous satellites. GPS is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth.

  • 1999 Cubesat Design Specification (CDS) and Poly-Picosatellite Orbital Deployer (P-POD)

    The CubeSat Design Specification (CDS) provides a framework for the design, construction and launch of Cubesats. A CubeSat is a class of miniaturized satellite based around a form factor consisting of 10 cm (3.9 in) cubes. CubeSats have a mass of no more than 2 kg (4.4 Ib) per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are put into orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle.

    The Poly-Picosatellite Orbital Deployer (P-POD) is a standard deployment system that can deploy up to three 1U cubesats. The P-POD plays a critical role as the interface between the launch vehicle and CubeSats. The P-POD minimizes potential interactions with the primary payload(s) on a launch vehicle by physically enclosing the Cube Sats and requiring that they be launched in a dormant “off” state.

The adapter design becomes a “defacto” standard.

  • 2009 Kessler Syndrome Revisited

    In 2009 Kessler published modeling results which concluded that the debris environment was already unstable, “such that any attempt to achieve a growth-free small debris environment by eliminating sources of past debris will likely fail because fragments from future collisions will be generated faster than atmospheric drag will remove them”. One implication is that the distribution of debris in orbit could render space activities and the use of satellites in specific orbital ranges difficult for many generations.

  • 2022 The Illusion of Smallsat Growth Between 2022 and 2031

    Over 18,500 smallsats (<500 kg) are forecast to be launched between 2022 and 2031. However this forecast gives the illusion of a huge growing market when in reality 81% of the smallsats launched during that period will be from a few mega constellations such as Starlink. Furthermore, the smallsat market faces a growing number of challenges e.g., limited market addressability, difficult profitability, oversupply and concentration of the commercial market in a handful of established players.

    The following trends are expected to result in an increase of the mass of individual satellites launched: continued decline in launch cost, satellite components standardization driving down time and cost to build, on-orbit servicing, desire for increased/multi capabilities, and the high ongoing cost of maintaining a large LEO smallsat constellation.

  • 2030E ISS Decommissioned

    No more cubesat launches from ISS.

  • 2040E The End of LEO Smallsat Communications Constellations

    In-Space Assembly and Manufacturing (ISAM) will allow the assembly of large structures in space, including large antenna structures which can redefine the satellite communications market.

    Satellite antenna size and the data throughput achievable in a satellite communications channel are directly related, but the benefits from an increased aperture size can also be used to enable access to smaller ground antennas or to improve QoS, as well as increase data throughput. As well as gain, increasing satellite antenna size also enables increased spatial discrimination, enabling greater frequency reuse across a given service area. With the satellite industry’s shift from a broadcast model to a connectivity-based approach comes increased competition with terrestrial networks, and a corresponding need to increase total system throughput and spectrum utilisation. The result has been greater interest in larger antenna systems for telecommunications missions. While increasing antenna aperture size will always result in a corresponding increase in link performance, if a significant step forward could be made, a tipping point might be reached allowing direct broadband access to hand-held devices from orbit. Such a step change would have a significant impact on the addressable market and range of applications that could be supported by the satcom sector.
