At Antares, our long-term mission is to make clean energy abundant, from earth to the asteroid belt. We’re fueled by the belief that energy abundance and a strong defense industrial base are the keys to unlocking growth in the American standard of living. That’s why we’re building transportable microreactors for the military.
Exlabs and Antares form alliance to develop nuclear-powered spacecraft, 2025-03-19.
- Exlabs’ initial missions, including its 2028 campaign to rendezvous with the asteroid Apophis, will not rely on nuclear power. But, the company’s modular spacecraft, called Science Exploration and Resource Vehicle (SERV), will be designed to accommodate Antares microreactors.
- Exlabs plans to send a spacecraft equipped with an Antares’ nuclear microreactor to geostationary orbit in late 2028 or 2029.
