NASA Advanced Mid-Power Electric Rocket Challenge

Mid-power (3-7 kW) Hall effect thruster systems have been identified by government and industry stakeholders as critical capabilities for satellite, defense, and exploration missions. Given the need for this capability, NASA is launching the Advanced Mid-Power Electric Rocket (AMPERE) Challenge. The NASA AMPERE Challenge invites U.S. commercial companies to develop and demonstrate mid-power Hall effect […]
