@myhumehealth - I bought one of your band and so far so bad! I paid but it doesn’t get delivered and you have no humans to help out. 0/5 on customer support. I hope to receive my band and never needing your support in the future
@KenKirtland17 Good point @KenKirtland17 . We could take the acoustic test system at the Cape but the TVAC requires a huge investment and it’s not portable.
It was an honor to host @NASAAdmin yesterday in Florida! Our Blue Moon MK1 lunar lander provided an amazing backdrop as we gear up for acoustic testing. 📷: NASA
And I had my hand on the noise control system creating the noise that replicates the 🚀! It was a blast! @davill , you have an amazing team that with passion, knowledge and dedication are writing a chapter of space history. I am privileged to have been their pen for a few lines!
This week we completed direct field acoustic testing on our Blue Moon MK1 lunar lander, a major flight‑qualification milestone.
We surrounded the fully integrated lander with a ring of 34‑ft speaker towers to generate a near‑diffuse acoustic field, matching the New Glenn payload fairing environment at over 138 decibels overall sound pressure level. MK1 ran in a flight-like configuration: tanks pressurized with helium and nitrogen, batteries powering the vehicle, with all critical avionics and guidance systems operating.
43 triaxial accelerometers measured response during a two‑minute exposure at protoqualification levels. Because the lander's vibration environment is driven by acoustic loads, this test replaces traditional shaker-based vibration testing and more accurately represents ascent conditions.
Next stop: @NASA_Johnson for thermal vacuum chamber testing.

@424BasilStreet sono sicuro che le sa che Newson and Trump non possono essere rivali per la Casa Bianca. @LaRepubblica_it una correzione sarebbe d’uopo
@whatever Finland and Sweden don’t have the oil of Norway . Norway comes after Costa Rica when it comes to happiness. His question about Norway is probably because it’s the only he knows
As the great @elonmusk would tweet: “Wow”

@Rainmaker1973 I tried the @Apple on the same photo (took a screenshot) and the result is exactly as show in this video. So I am assuming that the result of Galaxy is also true. In conclusion @Apple get your act together and do something useful and not just expensive!
@Rainmaker1973 The iPhone executes this which is correct as multiplication are computed first. The old calculator computes (50+50)x2, that is it puts parentheses at its choice
