History
Space Micro was founded in 2002 by David J. Strobel and David Czajkowski as their second entrepreneurial venture following the successful sale of their first company, Space Electronics, Inc., to Maxwell Technologies in 1999.
Since 2002, the company has designed, manufactured and launched hundreds of subsystems into space, accumulating millions of hours of space flight heritage. Subsystems have flown on spacecraft for NASA (LADEE, IRIS, TESS), JPL, Department of Defense, aerospace primes (Lockheed Martin, Boeing) as well as Airbus, ULA, Dynetics, Moog, Raytheon, and commercial space entities such as Astrobotic and Astroscale.
In 2022, Space Micro was acquired by Voyager Space Holdings.
A spacecraft is a vehicle that is designed to fly in outer space and operate there. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle.
Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable.
The European X-ray Observatory Satellite (EXOSAT), originally named HELOS, was an X-ray telescope operational from May 1983 until April 1986 and in that time made 1780 observations in the X-ray band of most classes of astronomical object including active galactic nuclei, stellar coronae, cataclysmic variables, white dwarfs, X-ray binaries, clusters of galaxies, and supernova remnants.
The Mars Telecommunications Orbiter (MTO) was a cancelled Mars mission that was originally intended to launch in 2009 and would have established an Interplanetary Internet between Earth and Mars. The spacecraft would have arrived in a high orbit above Mars in 2010 and relayed data packets to Earth from a variety of Mars landers, rovers and orbiters for as long as ten years, at an extremely high data rate. Such a dedicated communications satellite was thought to be necessary due to the vast quantity of scientific information to be sent to Earth by landers such as the Mars Science Laboratory.
Spacecraft design is a process where systems engineering principles are systemically applied in order to construct complex vehicles for missions involving travel, operation or exploration in outer space. This design process produces the detailed design specifications, schematics, and plans for the spacecraft system, including comprehensive documentation outlining the spacecraft's architecture, subsystems, components, interfaces, and operational requirements, and potentially some prototype models or simulations, all of which taken together serve as the blueprint for manufacturing, assembly, integration, and testing of the spacecraft to ensure that it meets mission objectives and performance criteria.
Astrionics is the science and technology of the development and application of electronic systems, subsystems, and components used in spacecraft. The electronic systems on-board a spacecraft are embedded systems and include attitude determination and control, communications, command and telemetry, and computer systems. Sensors refers to the electronic components on board a spacecraft.
The Lunar Atmosphere and Dust Environment Explorer was a NASA lunar exploration and technology demonstration mission. It was launched on a Minotaur V rocket from the Mid-Atlantic Regional Spaceport on September 7, 2013. During its seven-month mission, LADEE orbited the Moon's equator, using its instruments to study the lunar exosphere and dust in the Moon's vicinity. Instruments included a dust detector, neutral mass spectrometer, and ultraviolet-visible spectrometer, as well as a technology demonstration consisting of a laser communications terminal. The mission ended on April 18, 2014, when the spacecraft's controllers intentionally crashed LADEE into the far side of the Moon, which, later, was determined to be near the eastern rim of Sundman V crater.
TriDAR, or Triangulation and LIDAR Automated Rendezvous and Docking, is a relative navigation vision system developed by Neptec Design Group and funded by the Canadian Space Agency and NASA. It provides guidance information that can be used to guide an unmanned vehicle during rendezvous and docking operations in space. TriDAR does not rely on any reference markers positioned on the target spacecraft. Instead, TriDAR relies on a laser based 3D sensor and a thermal imager. TriDAR's proprietary software uses the geometric information contained in successive 3D images to match against the known shape of the target object and calculate its position and orientation.
SSETI Express was the first spacecraft to be designed and built by European students and was launched by the European Space Agency. SSETI Express is a small spacecraft, similar in size and shape to a washing machine. On board the student-built spacecraft were three CubeSat picosatellites, extremely small satellites weighing around one kg each. These were deployed one hour and forty minutes after launch. Twenty-one university groups, working from locations spread across Europe and with very different cultural backgrounds, worked together via the internet to jointly create the satellite. The expected lifetime of the mission was planned to be 2 months. SSETI Express encountered an unusually fast mission development: less than 18 months from kick-off in January 2004 to flight-readiness.
The Unified S-band (USB) system is a tracking and communication system developed for the Apollo program by NASA and the Jet Propulsion Laboratory (JPL). It operated in the S band portion of the microwave spectrum, unifying voice communications, television, telemetry, command, tracking and ranging into a single system to save size and weight and simplify operations. The USB ground network was managed by the Goddard Space Flight Center (GSFC). Commercial contractors included Collins Radio, Blaw-Knox, Motorola and Energy Systems.
The Laser Communications Relay Demonstration (LCRD) is a NASA mission that will test laser communication in space for extremely long distances, between Earth and geosynchronous orbit.
LituanicaSAT-1 was one of the first two Lithuanian satellites. It was launched along with the second Cygnus spacecraft and 28 Flock-1 CubeSats aboard an Antares 120 carrier rocket flying from Pad 0B at the Mid-Atlantic Regional Spaceport on Wallops Island to the International Space Station. The launch was scheduled to occur in December 2013, but later was rescheduled to 9 January 2014 and occurred then. The satellite was broadcasting greetings of Lithuanian president, Mrs. Dalia Grybauskaitė. The satellite was deployed from the International Space Station via the NanoRacks CubeSat Deployer on 28 February 2014. All LituanicaSAT-1 subsystems have been turned on, tested and proved to be working properly. The mission is considered a complete success by its team of engineers. The mission ended upon the reentry and disintegration of the satellite on 28 July 2014.
Laser communication in space is the use of free-space optical communication in outer space. Communication may be fully in space or in a ground-to-satellite or satellite-to-ground application. The main advantage of using laser communications over radio waves is increased bandwidth, enabling the transfer of more data in less time.
A ground segment consists of all the ground-based elements of a space system used by operators and support personnel, as opposed to the space segment and user segment. The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground. The primary elements of a ground segment are:
Lunar Flashlight was a low-cost CubeSat lunar orbiter mission to explore, locate, and estimate size and composition of water ice deposits on the Moon for future exploitation by robots or humans.
Lunar IceCube is a NASA nanosatellite orbiter mission that was intended to prospect, locate, and estimate amount and composition of water ice deposits on the Moon for future exploitation. It was launched as a secondary payload mission on Artemis 1, the first flight of the Space Launch System (SLS), on 16 November 2022. As of February 2023 it is unknown whether NASA team has contact with satellite or not.
The spacecraft bus is a carbon fibre box that houses systems of the telescope and so is the primary support element of the James Webb Space Telescope, launched on 25 December 2021. It hosts a multitude of computing, communication, propulsion, and structural components. The other three elements of the JWST are the Optical Telescope Element (OTE), the Integrated Science Instrument Module (ISIM) and the sunshield. Region 3 of ISIM is also inside the spacecraft bus. Region 3 includes the ISIM Command and Data Handling subsystem and the Mid-Infrared Instrument (MIRI) cryocooler.
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.
The Frontier Radio is a family of software-defined radios developed by the Johns Hopkins University Applied Physics Laboratory. Four variants have been developed: the Frontier Radio (FR), the Frontier Radio Lite, and the Frontier Radio Multi Lingual, and the Next-Gen Frontier Radio. In addition, the Frontier-S and Frontier-X are licensed derivatives manufactured by commercial aerospace company Rocket Lab.
OPTOS was a Spanish nanosatellite designed and developed by INTA with support from the European Cooperation for Space Standardization (ECSS) as a low-cost technology demonstrator. It was launched in 2013 and had a service life of three years.
