The competition heats up: NASA has awarded three different companies contracts to develop advanced ion and nuclear propulsion systems for future interplanetary missions, both manned and unmanned.
These are development contacts, all below $10 million. However, they all appeared structured like NASA’s cargo and crew contracts for ISS, where the contractor does all of the development and design, with NASA only supplying some support and periodic payments when the contractor achieves agreed-upon milestones. Because of this, the contractors will own the engines their develop, and will be able to sell them to other customers after development, thereby increasing the competition and innovation in the field.
