NASA announced the Advanced Mid-Power Electric Rocket (AMPERE) Challenge, which invites U.S. commercial companies to develop and demonstrate prototypes of mid-power Hall effect thrusters operating in the 3-7 kW range. The agency says government and industry stakeholders have identified such systems as critical for satellite, defense and exploration missions.

The challenge offers $500,000 in total prizes, with up to two winning teams each eligible for as much as $250,000 in cash, plus access to NASA testing and technology across three phases. NASA says the effort aims to speed maturation of electric propulsion, validate real-world performance in its test facilities and support future agency and commercial missions.

Eligibility is limited to companies incorporated in the United States with a primary place of business there. Registration opened November 9, 2026, and closes January 27, 2027. Rules and eligibility details are available on the challenge website.
