Busek was founded in 1985 by Vlad Hruby in Natick, Massachusetts.[1] Busek started as a laboratory outside of Boston, Massachusetts .
Flight missions
TacSat-2
Busek's BHT-200 hall effect thruster
The first US Hall thruster flown in space, Busek's BHT-200, was launched aboard the Air Force Research Laboratory's (AFRL) TacSat-2 satellite. The Busek thruster was part of the Microsatellite Propulsion Integration (MPI) Experiment and was integrated on TacSat-2 under the direction of the DoD Space Test Program. TacSat-2 launched on December 16, 2006 from the NASA Wallops Flight Facility.[2]
Aerojet, under license with Busek,[5][6] manufactured the 4 kW Hall thruster (the BPT-4000) which was flown aboard the USAF AEHF communications spacecraft.
OneWeb
In 2023, Busek announced the successful on-orbit commissioning of its BHT-350 Hall-effect thrusters on 80 OneWeb satellites, launched in December 2022 and January 2023 on SpaceXFalcon 9 rockets. The new OneWeb communications satellites use the thrusters for orbit-raising, station-keeping, collision avoidance and de-orbiting at the conclusion of each satellite’s mission.

Busek's BIT-3 ion thruster operating on several propellants
Busek has demonstrated experimental xenon Hall thrusters at power levels up to and exceeding 20kW.[9] Busek has also developed Hall thrusters that operate on iodine,[10][11]bismuth,[12][13]carbon dioxide,[14]magnesium,[15]zinc,[16] and other substances. An iodine fueled 200 W Busek Hall thruster will fly on NASA's upcoming iSat (Iodine Satellite) mission. Busek is also preparing a 600 Watt iodine Hall thruster system for future Discovery Class missions.[17]
As of July 2012[update], Busek was also working on a DARPA-funded program called DARPA Phoenix, which aims to recycle some parts of on-orbit spacecraft.[21]
In September 2013, NASA awarded an 18‑month Phase I contract to Busek to develop an experimental concept called a High Aspect Ratio Porous Surface (HARPS) microthruster system for use in tiny CubeSat spacecraft.[22][23]
In order to deal with space debris, Busek proposed in 2014 a remotely controlled vehicle to rendezvous with this debris, capture it, and attach a smaller deorbit satellite to the debris. The remotely controlled vehicle would then drag the debris/smallsat-combination, using a tether, to the desired location. The larger sat would then tow the debris/smallsat combination to either deorbit or move it to a higher graveyard orbit by means of electric propulsion. The larger satellite is named the Orbital Debris Remover, or ORDER which will carry over 40 SUL (Satellite on an Umbilical Line) deorbit sats and sufficient propellant for a large number of orbital manoeuvres required to effect a 40-satellite debris removal mission over many years. Busek is projecting the cost for such a space tug to be US$80 million.[25]
