The Saturn V carried man to the moon and remains the most powerful rocket to successfully launch to orbit. It captures the imagination—but sometimes, it might capture a bit too much imagination. Abundant internet claims about the acoustic power of the rocket suggest that it melted concrete and lit grass on fire over a mile away.
Such ideas are undeniably false. In The Journal of the Acoustical Society of America, researchers from Brigham Young University used a physics-based model to estimate the acoustic levels of the Saturn V. They obtained a value of 203 decibels, which matched the very limited data from the 1960s.
To put that number into perspective, commercial jet engines range from around 120 to 160 decibels.
"Decibels are logarithmic, so every 10 decibels is an order of magnitude increase," said author Kent L.

The Artemis I mission is almost ready for launch: it will send an uncrewed spacecraft beyond the Moon and back.
Watch the replay of this virtual Q&A to learn more about Europe's contribution to the mission: ESA is overseeing the development of the European Service Module, that provides air, electricity and propulsion to the spacecraft. Participants to this media briefing include Josef Aschbacher, ESA Director General ; David Parker, ESA Director for Human and Robotic Exploration ; Jean-Marc Nasr, Airbus EVP Space Systems and Marc Steckling, Airbus Head of Space Exploration

An agreement signed yesterday looks to extend the use of ESA space technology along European roads. The Agency’s Navigation Directorate has finalised a Memorandum of Intent with ERTICO, the organisation for the European Road Transport Telematics Implementation Coordination, a public-private partnership focused on the development, promotion and connection of intelligent road systems and services.
