Busek Co. Inc. is a spacecraft propulsion company providing thrusters, electronics, and complete systems for spacecraft.[1]

Busek spaceflight heritage includes the first US Hall thruster in space (TacSat-2),[2] the first electrospray thruster in space (LISA Pathfinder),[3] four micro-pulsed plasma thrusters flown aboard FalconSat-3,[4] and a BHT-200 Hall thruster flown aboard FalconSat-5.[5]

History

Busek was founded in 1985 by Vlad Hruby [1][6] and incorporated in Natick, Massachusetts. Starting as a small laboratory outside of Boston, Massachusetts, Busek facilities have expanded to over 20,000 square feet of laboratory, engineering, testing, and product assembly space.[7]

Flight missions

Busek products have spaceflight heritage on several missions, including:

LISA Pathfinder

The first spaceflight-qualified electrospray thruster was manufactured by Busek and launched aboard the European Space Agency's LISA Pathfinder satellite on December 3, 2015.[3] The micro-newton colloid-style electric thruster was developed under contract with NASA’s Jet Propulsion Laboratory (NASA ST-7 Program), and part of NASA’s Disturbance Reduction System (DRS) which serves a critical role in the LISA Pathfinder science mission.[8]

TacSat-2

Busek's BHT-200 hall effect thruster

The first US Hall thruster flown space, Busek's BHT-200, was launched aboard the Air Force Research Laboratory’s (AFRL) TacSat-2 satellite.[9] 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]

FalconSat-3

Busek delivered four MPACS (Micro-Propulsion Attitude Control Systems) that launched aboard the Air Force Academy’s FalconSat-3 mission on March 8, 2007 from Cape Canaveral. The MPACS are integrated micro-pulsed plasma thrusters (microPPTs)[10] and the first US-designed and built coaxial microPPTs in orbit. MPACS provides precise attitude control on small (< 100 kg) satellites and are valuable for missions requiring precise pointing (e.g., high-resolution imaging).[4]

FalconSat-5

Busek's Space Plasma Characterization Source was launched aboard the AFRL and USAF Academy's FalconSat- 5 satellite on November 2010.[11] The integrated unit consisted of an ammonia cold-gas thruster, a BHT-200 Hall effect thruster, high speed plasma probe, neutral source, propellant management system, Power Processing Unit (PPU), instrument electronics, and Digital Control Interface Unit (DCIU).[5]

AEFH

Aerojet, under license with Busek,[12][13] manufactured a 4 kW Hall thruster (the BPT-4000) which was flown aboard the USAF AEHF communications spacecraft. The thruster is credited with saving the first satellite by raising it to geosynchronous orbit after failure of the spacecraft's main apogee engine.[14]

Research and development

Propulsion

Busek's BIT-3 ion thruster operating on several propellants

Busek has demonstrated a variety of experimental xenon Hall thrusters at power levels up to and exceeding 20 kW.[15] Busek has also developed Hall thrusters that operate on iodine,[16][17] bismuth,[18][19] carbon dioxide,[20] and other substances.

In 2008, a Busek Hall thruster appeared in National Geographic.[21] Other publicized Busek technologies include RF ion engines[16][22] and a resistojet rocket.[23] Another focus is CubeSat propulsion,[16] proposed for the 2018 Lunar IceCube mission.[24]

As of July 2012, Busek was also working on a DARPA-funded program called DARPA Phoenix, which aims to recycle some parts of on-orbit spacecraft.[25]

In September 2013, NASA awarded an 18‑month Phase I contract to Busek to develop an experimental concept called High Aspect Ratio Porous Surface (HARPS) microthruster system for use in tiny CubeSat spacecraft.[26][27]

ORbital DEbris Remover (ORDER)

In order to deal with human-caused space debris, Busek proposed in 2014 a remotely controlled vehicle to rendezvous with debris, capture it, and attach a smaller deorbit satellite to the debris, then drag the debris/smallsat-combination, by means of 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 plus sufficient propellant for the large number of orbital maneuvers 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.[28]
