Momentus will have its first launch June 27, 2019. They have $9 million in seed funding and have $20 million in customer contracts. The first mission is called El Camino Real and is the pathfinder mission.
Joel Sercel is presenting on Momentus Space’s Water-Plasma Propelled In-Space Transportation Services.
The system is super-safe and can be transported on the seat of a commercial airplane.
In 3-4 years, there will be 1500 small sats launched per year without including the mega-constellation satellites and Momentus sees these small satellites as a large potential market.
$1.2 million for 1 kilometer per second of delta-V for the Vigoride product.
All later systems on their roadmap have 6 kilometers per second of delta-V.
They use microwaves to heat water. A resonant cavity superheats water to plasma (ionized gas) at several thousand degrees kelvin.
Vigoride Extended will be able to take 200 kilogram from low-earth orbit to lunar orbit. It could take 300 kilograms from low-earth orbit to GEO.
The cost would be $100,000/kg.
Ardoride would be able to move a few thousand kilograms.
They will have 2 to 3 times the ISP of chemical rockets.
They can dispense multiple satellites in different orbits and keep going.
