The awards reflect leadership in the aerospace business community and sustained achievement in service to Marshall and to NASA’s overarching mission.
NASA Tests First 3-D Printed Rocket Engine Part Made with Two Different Alloys
Marshall engineers have tested NASA’s first 3-D printed rocket engine prototype part made of two different metal alloys through an innovative advanced manufacturing process. NASA has been making and evaluating durable 3-D printed rocket parts made of one metal, but the technique of 3-D printing, or additive manufacturing, with more than one metal is more difficult.
Three Spacewalks Scheduled for the International Space Station
The International Space Station‘s Expedition 53 crew is gearing up for three maintenance spacewalks set to take place in October over a period of two weeks. During the spacewalks, NASA astronauts Randy Bresnik, Mark Vande Hei and Joe Acaba will work on the Canadarm2 robotic arm and replace cameras on the station’s truss.
NASA’s OSIRIS-REx Make Close Approach to Earth en Route to Near-Earth Asteroid
NASA’s OSIRIS-REx spacecraft made a close approach to Earth Sept. 22, using the planet’s gravity to slingshot itself toward its ultimate destination, Bennu — a near-Earth asteroid. Observatories and amateur astronomers with specialized equipment viewed the spacecraft as it approached and retreated from its closest position over Earth, approximately 11,000 miles.
Two Stars, Three Dimensions, and Oodles of Energy
For decades, astronomers have known about irregular outbursts from the double star system V745 Sco, which is located about 25,000 light years from Earth. Caught by surprise in 1937 and 1989, where ready when the system erupted on Feb. 6, with a suite of telescopes including NASA’s Chandra X-ray Observatory.
