What's stopping Rocket Lab from expanding the capabilities of the kick stage, and effectively do what this company is trying to do by marketing it? Curie has the flight heritage under its belt.

Electron's performance. 150–225 kg to LEO leaves almost zero margin for hardware that isn't payload. Vigoride will weigh no less than 80 kg wet per Momentus' website, meaning that the limits of Electron would be ~140 kg to a 700 km elliptical orbit with Vigoride providing a max of 1 km/s dV (for a 50 kg payload) from there. That is by no means shabby but it's really hard to conceive of more than a tiny handful of customers for something like that.



Electron market may not be that big for them especially as Curie does alot of what Vigoride does. Their larger tugs when used with new range of 1000-1250kg LVs is lot more interesting. Delivering smallsats to GEO and Lunar orbit.

Would be good to know the name of their test satellite and launch vehicle.

"Momentus plans to conduct an in-orbit demonstration of its key technology, a water-plasma engine, in March or April."

IIRC, Astro Digital (another company the Momentus CEO is financially involved with) is building the bus for their demo flight. Based on past history, my guess is they'd be going up on either a Soyuz or a PSLV.
