Jan 11, 2021   |   by Julie Bonette A team of eight Dartmouth engineering students was awarded Best Technical Paper at NASA’s Breakthrough, Innovative and Game-changing (BIG) Idea Challenge. The team was one of eight finalists selected from across the country to present lunar exploration technology concepts and prototypes at the BIG Idea Challenge virtual forum earlier this month. The Dartmouth team’s idea, "SHREWs: Strategic Highly-compliant Roving Explorers of other Worlds," focuses on mobility achieved through a class of robots able to latch on to each other to minimize the chance o...

NASA reports 3D Printed Rocket Engine Parts make it through 23 Hot-Fire Tests   Huntsville, AL – Future lunar landers might come equipped with 3D printed rocket engine parts that help bring down overall manufacturing costs and reduce production time. NASA is investing in advanced manufacturing – one of five industries of the future – to make it possible. Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured engine components – a copper alloy combustion chamber and nozzle made of high-strength hydrogen resistant alloy – could withstand th...

[1] – to make it possible. Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured engine components – a copper alloy combustion chamber and nozzle made of high-strength hydrogen resistant alloy – could withstand the same extreme combustion environments that traditionally manufactured metal structures experience in flight. Hot-fire testing of an additively manufactured copper alloy combustion chamber and a nozzle made of a high-strength hydrogen resistant alloy.

By Hillary Smith NASA’s Game Changing Development Program HUNTSVILLE, Ala. — Future lunar landers might come equipped with 3D printed rocket engine parts that help bring down overall manufacturing costs and reduce production time. NASA is investing in advanced manufacturing – one of five industries of the future – to make it possible. Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured engine components – a copper alloy combustion chamber and nozzle made of a high-strength hydrogen resistant alloy – could withstand the same extreme ...
