Antares achieves zero-power criticality at INL
Leveraging more than $140 million in private capital fundraising, over 322,000 square feet of operational manufacturing space, and multifaceted partnerships with the Departments of Energy and Defense, reactor start-up Antares has become the first company involved in the Reactor Pilot Program to achieve zero-power fueled criticality—a full month ahead of the July 4 deadline set by President Trump’s Executive Order 14301.
This milestone, announced yesterday, was achieved with the company’s Mark-0: a sodium heat-pipe-cooled, TRISO-fueled microreactor. The Mark-0 is a forerunner to the company’s flagship design, which it calls the R1. For Antares, this development represents a key validation of its reactor physics, control systems, and supply chain.

Magnetoplasma Sail (MPS) is one of the sail propulsion system using the solar wind and suitable for deep space exploration. MPS uses an artificial magnetic field for capturing the solar wind, which is generated by a combination of a coil and a plasma injection. In order to measure thrust of a miniature MPS directory, a parallelogram-pendulum-type thrust stand was developed and installed on MPS ground simulator. In comparison with 0.6 N of Magnetic Sail thrust for 90 mm-magnetosphere, when the magnetospheric size for 115 mm was produced, 4.0 N thrust of the miniature MPS was obtained. The thrust value may include thrust originated with MPD arcjets used for magnetospheric inflation. Our next step of thrust measurement is evaluation of thrust increment for magnetospheric inflation.
