[Epsilon3](https://www.g2.com/products/epsilon3/reviews) By Epsilon3 **Average Rating:** 4.2/5 **Total Reviews:** 260 Software for complex engineering, testing, and operational procedures. At Epsilon3, we modernize space missions and complex engineering and testing by building the industry standard of operational software. We are a team of engineering and design leaders from Northrop, Google, and SpaceX, where we ran operations first-hand to bring American astronauts to the ISS. Current mission tools are neglected in a program lifecycle, creating inefficiency, errors, and added costs over the course of a project. Epsilon3 arms operators with the best possible tools throughout an entire project’s lifecycle, which result in 10X more efficiency and operator-friendliness.
