The type of vehicle that will carry people to the Red Planet is shaping up to be “like a two-story house you’re trying to land on another planet. 

ORNL Director Thomas Zacharia (center, seated) visited Robertsville Middle School to present a check in support of the school’s CubeSat efforts.

Last November a team of students and educators from Robertsville Middle School in Oak Ridge and scientists from Oak Ridge National Laboratory submitted a proposal to NASA for their Cube Satellite Launch Initiative in hopes of sending a student-designed nanosatellite named RamSat into...

By producing 50 grams of plutonium-238, Oak Ridge National Laboratory researchers have demonstrated the nation’s ability to provide a valuable energy source for deep space missions.

With the production of 50 grams of plutonium-238, researchers at the Department of Energy’s Oak Ridge National Laboratory have restored a U.S. capability dormant for nearly 30 years and set the course to provide power for NASA and other missions.

Since its 1977 launch, NASA’s Voyager 1 spacecraft has travelled farther than any other piece of human technology. It is also the only human-made object to have entered interstellar space. More recently, the agency’s New Horizons mission flew past Pluto on July 14, giving us our first close-up lo...
