Rocket Lab Expands Space Systems Footprint with New High Volume Reaction Wheel Production Facility

The new production facility comes as Rocket Lab secures contracts to supply major satellite constellations with reaction wheels
LONG BEACH, Calif., September 1, 2021 (Rocket Lab PR) – Rocket Lab USA, Inc. (Nasdaq: RKLB) (“Rocket Lab” or the “Company”), global leader in launch and space systems, today announced that construction is underway on a new production facility capable of supplying up to 2,000 reaction wheels per year to fulfil growing demand from satellite constellation customers.
The new production facility, which joins Rocket Lab’s existing 380,000 sq/ft manufacturing footprint, comes as Rocket Lab signs deals to supply reaction wheels for a number of undisclosed satellite constellations. The production line incorporates advanced metal machining centers optimized for unattended operation, automated production tools, and automated environmental testing workstations. More than 16 new roles are expected to support the new production facility and the growing Space Systems operations at Rocket Lab by the end of the year.
The new production facility is the latest expansion of Rocket Lab’s Space Systems business, which was strengthened in 2020 by the acquisition of Toronto-based Sinclair Interplanetary, a leading provider of high-quality, flight-proven satellite hardware including reaction wheels and star trackers. Sinclair Interplanetary pioneered high-reliability reaction wheels for small satellites and there are close to 200 wheels currently operating on orbit.
Rocket Lab founder and Chief Executive Officer, Peter Beck, said the new production facility leverages Sinclair Interplanetary’s heritage and marries it with Rocket Lab’s extensive experience with high-rate manufacture of aerospace components for the Electron launch vehicle to make what the Company considers best-in-class satellite hardware available to customers at scale.
“For the longest time, spacecraft and satellite components have been built individually by highly specialized engineers with a high price tag and long wait times to match. With the rise in constellations, the demand for high-quality components and spacecraft produced at scale continues to grow and we’re addressing the bottleneck head on. Halfway through 2021, we had already surpassed the total number of satellite components produced by Sinclair annually and we’re continuing to accelerate production to meet the needs of our customers.”
Rocket Lab satellite components, including reaction wheels and star trackers, are now used in more than 200 satellites globally including industry-leading constellations BlackSky and Kepler Communications. Since acquiring Sinclair Interplanetary, Rocket Lab has added 2,700 sq/ft of production facilities to the Sinclair Interplanetary facilities in Toronto, Canada and expanded the team to support higher production volume and enable R&D for new satellite hardware and products.
About Rocket Lab
Rocket Lab is a global leader in space, building rockets and spacecraft that make it easier to get to orbit and to do amazing things there. Founded in 2006, Rocket Lab provides end-to-end mission services that provide frequent and reliable access to space for civil, defense, and commercial markets. Headquartered in Long Beach, California, Rocket Lab designs and manufactures the Electron launch vehicles and Photon satellite platform and is developing the Neutron launch vehicle. Since its first orbital launch in January 2018, Rocket Lab’s Electron launch vehicle has become the second most frequently launched U.S. rocket annually and has delivered 105 satellites to orbit for private and public sector organizations, enabling operations in national security, scientific research, space debris mitigation, Earth observation, climate monitoring, and communications. Rocket Lab has two launch sites, including a private orbital launch site located in New Zealand, and a second launch site in Virginia, USA expected to be operational by the end of 2021. Rocket Lab’s Photon spacecraft platform has been selected to support NASA missions to the Moon and Mars, as well as the first private commercial mission to Venus.

He missed one option: wheel de-saturation without using propellant. However, I’m not surprised because this is something of a emergency mode like that used by Kepler, though it could be considered similar in principle to a magnetorquer (i.e. de-saturation by reaction against an external field/flux).
I’m familiar with this because last year the INTEGRAL telescope ran too low on propellant and its RCS became sufficiently unreliable to de-saturate the reaction wheels. We therefore developed a ‘Z-flip’ strategy to control angular momentum accumulated from external torques – primarily from solar radiation – by essentially flipping the spacecraft 180deg around the Sun axis (Z) roughly once every orbit. Needless to say, it works and INTEGRAL continues to produce excellent gamma-ray and X-ray data over a year later… and providing yet more proof that Newton was right 🙂
Maybe this is a dumb question, but could a reaction-wheel combine function with a flywheel power-storage? So desaturation of a reaction-wheel by means of using it like a flywheel powered generator?

Two flywheels stacked with their spin axes aligned but spun-up to the same speeds at the same rates but in opposite directions would store energy while accumulating zero overall angular momentum within the spacecraft. Reversing the process exactly would then allow energy extraction without disturbing the spacecraft’s attitude. However, extracting energy asymmetrically would cause the spacecraft to slew so, in principle, the functions of energy storage and attitude control could be combined in this way.
Unfortunately, I suspect this approach would only be beneficial to a very narrow range of spacecraft as you would be trading savings in battery mass against additional wheel mass and possible restrictions on slew size and pointing accuracy – especially when passing slowly through the zero speed region. I don’t know if this has been seriously considered but suspect it was in the early days when battery mass was much more constraining. Having said that, wear, stability and reliability issues raised by mechanical bearings, especially if they have to support significant side loads, may have been a big put-off.
