How Loud are the Launches? New Study Measures SpaceX’s Acoustic Levels
A recent study has unveiled the true sound levels generated by SpaceX’s Starship during its initial launch, drawing comparisons with NASA’s Space Launch System (SLS) and the Falcon 9. Conducted following the April 2023 launch of Starship, this analysis provides crucial insights into acoustic impacts, which are important for addressing environmental concerns and mitigating noise pollution near launch sites.
The study highlights that while the Falcon 9 and SLS share similar sound profiles, Starship presents higher acoustic levels, likely due to its larger thrusters and different launch dynamics. Understanding these differences aids in the refinement of launch protocols and environmental compliance, key considerations for future missions.

Space-Flown Seeds: A Unique STEM Experiment with Choctaw Nation
An intriguing STEM experiment is set to take place as heirloom seeds from the Choctaw Nation, previously flown on the International Space Station, will be planted on Earth. These seeds, brought back from space last year, will be compared to those planted directly on Earth to assess any differences in their growth and development.
This experiment aims to engage students and researchers, offering a hands-on learning opportunity about the effects of spaceflight on biological materials. Such projects are vital for educational outreach and inspire the next generation of scientists and space explorers.
