Antares is building compact nuclear microreactors to deliver reliable, mobile energy where it’s needed most: remote military bases, austere industrial sites, and, one day, deep space and underwater missions. The team includes engineers, operators from SpaceX, Relativity Space, Ursa Major, MIT, Rigetti Computing, and the U.S. Air Force.
