Momentus announces new customer for its cubesat upper stage services

Capitalism in space: Momentus, an company that is offering an upper stage to move tiny cubesats into higher orbits after launch, has announced that the United Kingdom cubesat company SteamJet has purchased that upper stage for use when its next satellite is launched on a Russian Soyuz rocket later this year.

Momentus’s approach signals a fundamental change that commercial space is now undergoing. Traditionally the launch company would provide this kind of service, but for cubesats flying as secondary payloads that isn’t possible. Momentus is thus taking it on as an independent secondary launch service for cubesats alone. With this announcement the company already has five customers, with launches scheduled for the next two years.

SteamJet also is most intriguing along these same lines.

Once in orbit, SteamJet intends to demonstrate a propulsion system that uses water or another low pressure, non-toxic, non-corrosive fluid propellant to create thrust. SteamJet houses its propulsion system in a module shaped like a tuna can that attaches to the exterior of a cubesat.

A lot of exciting things are going to be happening in space in this coming decade, and almost all will be because of private enterprise, freedom, and competition, fueled by profit.
