It Actually Is Rocket Science: 2021 Student Launch Competition Opens
Every year, NASA challenges middle school, high school, college, and university students from around the United States to design, build, test, and fly a high-powered amateur rocket to at least 3,500 feet above the ground, and then land. In order to compete, interested teams must submit a proposal to the NASA Student Launch program by 3 p.m. CDT Sept. 21. Selected teams will be announced in early October.

Future Rocket Engines May Include Large-Scale 3D Printing
NASA engineers are exploring a new way to 3D print rocket engine parts using metal powder and lasers. The method, called blown powder directed energy deposition, is faster and more affordable than conventional fabrication methods. The development is part of NASA’s Rapid Analysis and Manufacturing Propulsion Technology, or RAMPT, project.

Engineers Complete 5th Green Run Test of Space Launch System Core Stage
Engineers have completed the fifth of eight Green Run tests on the core stage of NASA’s new Space Launch System rocket, continuing progress toward a milestone hot fire test this fall. Operators concluded a test of the stage’s thrust vector control system on the historic B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, on Sept. 13. The test provided critical verification of the control system and its related hydraulics as operators gimbaled the stage’s four RS-25 engines just as they must move during flight to steer the rocket and maintain a proper trajectory.

OSIRIS-REx Sampling Area to Sclae
The OSIRIS-REx team released animations showing a size comparison of the planned sample collection area before and after the spacecraft arrives at near-Earth asteroid Bennu. The original mission plan envisioned a sample site with a diameter of 164 feet (50 meters), but the sampling region has been determined to be approximately 26 feet (8 meters) in diameter.
