MMRTG

Vendor profile

Overview

MultiMission Radioisotope Thermoelectric Generator (MMRTG), was designed with the flexibility to operate on planetary bodies with atmospheres, such as at Mars, as well as in the vacuum of space. An MMRTG generates about 110 watts of electrical power at launch, an increment of power that can be matched with a variety of potential mission needs. As with prior RPS, ensuring a high degree of safety is also a fundamental consideration.

Summary: For more than 60 years, NASA has been breaking barriers to achieve the seemingly impossible—from walking on the Moon to pushing the boundaries of human spaceflight farther than ever before. We work in space and around the world in laboratories and wind tunnels, on airfields and in control rooms to explore some of life’s fundamental mysteries: What’s out there in space? How do we get there? And what can we learn that will make life better here on Earth? We are passionate professionals united by a common purpose: to pioneer the future in space exploration, scientific discovery and aeronautics research. Today, we continue NASA’s legacy of excellence and innovation through an unprecedented array of missions. We are developing the most advanced rockets and spacecraft ever designed, studying the Earth for answers to critical challenges facing our planet, improving the air transportation experience, and so much more.
