Explorer is designed to do something no spacecraft has done to date: use its own propulsion system to go from low Earth orbit to an Earth departure trajectory. We designed this spacecraft to take advantage of the relatively low cost and high availability of commercial rideshare launches to low Earth orbit. With this capability, we enable many exploration and high delta-V applications from geosynchronous orbit, to near-Earth asteroids, to destinations as far away as Mars.

Great Performance

The ESPA sized Explorer can give a 10 kg payload a delta-V capability of approximately 5 km/s, taking it from low Earth orbit into interplanetary space. It then provides all of the services a stand-alone mission requires, including deep space communications, navigation, attitude control, thermal control, and substantial payload power. For maneuvering close to celestial objects, Explorer’s Reaction Control System offers full six degree of freedom propulsive maneuvers.

Easy Integration

Explorer has flexible payload interfaces, but also takes advantage of standard CubeSat formats. So, a payload designed to these standards is extremely easy to integrate. The spacecraft effectively acts as a propulsion, communications, control and navigation platform taking your instruments into deep space.

Flexible and Quick

Explorer can launch on a variety of commercial rideshares to low Earth orbit, and decouples launch timing from orbit raising and Earth departure maneuvers. This gives its missions significant independence. Plus, this spacecraft can go from contract to flight in one year.
