Another year of NASA's Human Exploration Rover Challenge has crossed the finish line! 🏁

The annual engineering competition – one of NASA’s longest-standing challenges – held its concluding event April 19 and April 20, at the U.S. Space & Rocket Center in Huntsville, Alabama, near NASA’s Marshall Space Flight Center.

More than 600 students with 72 teams participated as HERC celebrated its 30th anniversary as a NASA competition. Participating teams represented 42 colleges and universities and 30 high schools from 24 states, the District of Columbia, Puerto Rico, and 12 other nations from around the world. Teams were awarded points based on navigating a half-mile obstacle course, conducting mission-specific task challenges, and completing multiple safety and design reviews with NASA engineers.

🚀 Ready for testing!

The payload adapter test article has reached a critical milestone as it prepares for testing here at Marshall Space Flight Center. Made of metal rings and composite panels, the adapter will be part of the SLS (Space Launch System) Block 1B configuration, housed inside the universal stage adapter, and will make its debut during the Artemis IV mission.

Watch as technicians prepare the payload adapter for testing.

NASA achieved a major milestone April 3 for production of new RS-25 engines to help power its Artemis campaign to the Moon and beyond with completion of a critical engine certification test series at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

The 12-test series represents a key step for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to build new RS-25 engines, using modern processes and manufacturing techniques, for NASA’s SLS (Space Launch System) rockets that will power future lunar missions, beginning with Artemis V.

Three new sonifications of images from NASA’s Chandra X-ray Observatory and other telescopes have been released. Sonification is the process of translating data into sounds. In the case of Chandra and other telescopes, scientific data are collected from space as digital signals that are commonly turned into visual imagery. The sonification project takes these data through another step of mapping the information into sound.

The first sonification, IC 443 is a supernova remnant, or the debris of an exploded star, which astronomers have nicknamed the Jellyfish Nebula. A visual composite image of IC 443 includes X-rays from NASA’s Chandra X-ray Observatory and German ROSAT X-ray telescope (blue) along with radio data from the NSF’s Very Large Array (green) and optical data from the Digitized Sky Survey (red). The sonification of IC 443 begins with a top-down scan as the brightness of the data is correlated to the volume of the sound. The sounds are mapped to colors in the image with red light being heard as lower pitches, the green as medium, and the blue light as the higher pitches. This creates notes that sweep up and down in pitch continuously. Several colors are isolated and control the volume of sustained tones with red controlling the lowest note and white controlling the highest note. The background stars in the optical image have been converted to water drop sounds in the sonification.

Started in 2020, the NASA sonification project built off of other Chandra projects aimed at reaching blind and visually-impaired audiences. It has since shown to be meaningful to that community but also impacts much wider audiences, finding listeners through traditional and social media around the world.

A test version of the universal stage adapter for NASA's SLS (Space Launch System) rocket has been on the move at NASA's Marshall Space Flight Center in Huntsville, Alabama, and is now ready for testing. Following its delivery to Marshall by barge from nearby Decatur, teams moved and installed it onto the test stand in Building 4619 on March 12. Standing 32.4 feet tall and measuring 27.6 feet in diameter at its largest point, the universal stage adapter will connect NASA's Orion spacecraft to the core stage and provide additional cargo space for the future Block 1B configuration of the mega-rocket, beginning with Artemis IV. Leidos is the lead contractor for the adapter, which is a first-time build for the SLS rocket. For more information about SLS, visit www.nasa.gov/sls
