The Transorbital Expedition Vehicle (or TEV) is a small transporter of micro-satellites at long-range capable of sending 25kg to the Moon, starting from the low orbit.
Now the space economy relies on miniaturised satellites typically called microsatellites and CubeSats, capable of reproducing in constellations the functions of the big and old satellites but with a significantly reduced price, also accessible to newborn private companies. Unfortunately, the higher orbits are still not yet reachable by these satellites due to the massive quantities of the chemical fuel required.
Endowed of water-solar electric propulsion the TEVs are meant to be mounted on satellites.
The main structure of our satellites is composed by the Artank, a slightly inflatable structure that works as both fuel tank and solar array surface, reducing the effect of ionizing radiation, optimizing the structural mass and being a non-moving-parts solar array deployment system. In this way every mission can be studied individually, aiming to trajectories and exploring scenarios that could be otherwise impossible; for example, long-duration flights in the extremely low Earth orbit (ELEO), orbital plane shifts, transitions of constellations in the geostationary orbit, lunar missions and interplanetary trajectories.
