ViviSat, a new 50-50 joint venture of U.S. Space and ATK, is marketing a satellite-refueling spacecraft that connects to a target spacecraft using the same probe-in-the-kick-motor approach as MDA, but does not transfer its fuel. Instead, the vehicle becomes a new fuel tank, using its own thrusters to

with direct human assistance. The goal is to extend its operational life by five years via in-orbit stationkeeping. After the Intelsat 901 mission ends, MEV-1 is designed to be able to dock and undock additional times, potentially enabling it to service additional satellites.

Key to the business model is MDA's ability to launch replacement fuel canisters that would be grappled by SIS and used to refuel dozens of satellites over a period of years. These canisters would be much lighter than the SIS vehicle and thus much less expensive to launch

MEV‑1 has the ability to dock and undock several times during its 15 year design life, allowing it to service multiple customers. SpaceLogistics' initial service, using the MEV‑1, will extend the life of the Intelsat 901 satellite for five
