When the Artemis 1 mission was launched by NASA's Space Launch System, SLS, in November, it became the world's most powerful rocket, exceeding the thrust of the previous record holder, Saturn, by 13%. With liftoff came a loud roar heard miles away.
In JASA Express Letters, researchers from Brigham Young University and Rollins College in Florida reported noise measurements during the launch at different locations around Kennedy Space Center.
The data collected can be used to validate existing noise prediction models, which are needed to protect equipment as well as the surrounding environment and community. These data will be useful as more powerful lift vehicles, including the SLS series, are developed.
"We hope these early results will help prevent the spread of possible misinformation, as happened with the Saturn 5," author Kent Gee said. "Numerous websites and discussion forums suggested sound levels that were far too high, with inaccurate reports of the Saturn 5's sound waves melting concrete and causing grass fires.

NASA's Interstellar Mapping and Acceleration Probe (IMAP) spacecraft has completed the Mission Critical Design Review and is on track to meet its scheduled 2025 launch. Southwest Research Institute (SwRI) is managing the payload office, providing the scientific instrument Compact Dual Ion Composition Experiment (CoDICE) and is participating on other instrument teams for the mission, which will study the interaction between the solar wind and the interstellar medium as well as the fundamental processes of particle acceleration in space.

New information about an emerging technique that could track microplastics from space has been uncovered by researchers at the University of Michigan. It turns out that satellites are best at spotting soapy or oily residue, and microplastics appear to tag along with that residue.
