Portal Space Systems Wants to Build the Delivery Van, Tow Truck and Fighter Jet of Orbit
Launch got cheaper. Movement after launch did not. Portal is betting that sunlight, ammonia and a 3D-printed thruster can turn satellites from fixed infrastructure into vehicles - if its ambitious flight program catches up with the pitch.
General Galactic
General Galactic is an El Segundo, California deep-tech startup building water-based propulsion and propellant-generation systems for spacecraft. Its Genesis platform splits water via electrolysis into hydrogen and oxygen, powering a multimode engine that pairs high-thrust chemical burns with efficient electric maneuvering. Founded in 2023 by Stanford-trained, ex-SpaceX and ex-Varda engineers, the company frames itself as the future 'energy and logistics company' of the solar system - and is applying the same electrolysis reactor tech on Earth to turn waste CO2 into fossil-free natural gas.
