Mostly my stories. 😁 One student's mistake is another student's learning opportunity, right?

At #ASA182, attending the sonic boom session. Joe Salamone from , in response to a question about doing a particular analysis: "I'm not sure the juice is worth the squeeze." Love it.

Carson Cunningham presented his analysis of the #noise from the ULA Altas V launch of the NASA Landsat 9 satellite. #ASA182 #PASCAL

Fantastic news! BYU undergrad Matthew Yancey just presented on a noise analysis from the first Alpha launch, recorded at Vandenberg Space Force Base. #ASA182 BYU Acoustics Acoustical Society of America

Impressive presentation by Matthew Yancey at #ASA182. He was able to acoustically identify when one of the four engines shut down about 14 seconds into the first Alpha launch. Looking forward to the next Alpha launch this summer!

There is a definite wow factor but I'm not sure everyone will always agree with this sentiment. Here's a brief summary of a paper on the Falcon 9 sonic boom delivered yesterday at #ASA182. acoustics.org/2apaa6-boom-bu…

With our fight 2 #ToTheBlack launch campaign underway, take a look back at our journey to orbit.

🎉Congratulations to Prof. Brian Anderson for being elected to Fellow of the Acoustical Society of America! His citation notes his "contributions to applications of acoustic time reversal and acoustics education". Keep up the great work, Brian! Acoustical Society of America

What happens when a major rocket launch scrubs? These BYU students are taking "Enter to learn, go forth to serve" to heart. Proud of them.

📢 Announcement: Firefly has been selected by The U.S. Space Force’s (USSF) Space Systems Command (SSC) to provide launch services for SSC’s VICTUS NOX mission to demonstrate end-to-end Tactically Responsive Space capabilities. ow.ly/TtSZ50L1Vqc

Sounds to Astound is awesome! See you there!

.NASA is targeting the next launch attempt for the #Artemis I mission for Nov. 14. ARCHIVED: NASA's Exploration Ground Systems teams will roll the ARCHIVED: NASA_SLS rocket and Orion Spacecraft spacecraft to the launch pad as early as Nov. 4: go.nasa.gov/3CRGKhZ

If you want to learn about launch vehicle noise, I recommend two articles. 1st: an overview of launch vehicle noise research: acousticstoday.org/from-sputnik-t… 2nd: a technical review article covering many topics, including Mach waves and launch pad noise: doi.org/10.1121/10.000…

Earlier this month, Cedar Park's Firefly Aerospace launched its Alpha rocket into orbit from a launchpad at Vandenberg Space Force Base in California trib.al/0ZBbWvV

Rocket noise session going on all day in Chicago C at the Acoustical Society of America #ASA184. Come join us! A lot of fun talks ahead.
