Only surround yourself by people who want you to succeed and are willing to sacrifice their time to help you do so. Happiness is key to a successful life.

@joebarnard Great interview question, might use this later 👀

[Ethan McCowan @EthanMccowan]

@Astro_Chuck COPV When?

[Ethan McCowan @EthanMccowan]

@joebarnard Entropy or something like that

[Ethan McCowan @EthanMccowan]

@MayHow42 @lrocket @Astro_Chuck I’ve worked for 4 different aerospace companies, and they’ve all used NX. It’s very powerful and has good integration with their teamcenter application in production environments.

On the test stand Aeon R fires at 100% power for 180 seconds 🔥

📍 @NASAStennis, R Complex
🚀 180 seconds of hot fire = the max duration for a Terran R first stage flight plus margin.
🔁 Test, learn, iterate, repeat.

[Tim Ellis @thetimellis]

3 full iterations on Aeon R engine design + test already. Quite different between designs, this means Terran R will be more mature and advanced for reliable reusability and performance by the time it flies in 2026

@kegrocket Tribolube 71! Might be a good alternative depending on the application

@Apple any chance I can get a new 13” M4 IPad pro to replace my 1st generation iPad Pro I used to get my engineering degree? 👀

It has been nonstop smiles since Saturday, but we can't decide whether it is from the successful launch and recovery of the rocket or graduation this Friday... we are leaning more towards rocket.

[Queen City Rocketry @UCSpaceportCup]

On Saturday, the team successfully launched our rocket and had successful ejection of the payload capsule. Battling 15 mph winds, the team was able to achieve an altitude of 7,184 ft. The rocket and payload capsule were both recovered with minimal damage.

Have a little bit of rocket with your coffee this morning.

Our real time rail launch is then followed by a 1/8th speed video. Are you able to see the Mach diamond?

Our payload system utilizes compressed nitrogen to expel our capsules from their bays. Table testing proved the system delivers a sufficient force to break the shear pins holding the capsules during assembly and ascent. Our balcony testing validated the parachute deployment.

[Queen City Rocketry @UCSpaceportCup]

Our rocket will separate into three separate, connected, sections during recovery: lower body tube, avionics bay and upper body tube. The lower body tube has our fins, motor and motor mount tube. Our avionics bay is just as it sounds, a small section containing the rocket avionic

The CEAS Expo is happening on Tuesday, April 9th from 12:00 - 5:00 PM at the Duke Energy Convention Center. Stop by our booth to learn more about our rocket system and discover all the other senior capstone projects worked on throughout this year. See you there!

Mrs. Williams was my 5th grade science teacher 12 years ago and was the teacher who got me hooked on space. It was exciting to go back to her classroom and inspire the next generation of scientists and engineers! The future is bright indeed.

[Queen City Rocketry @UCSpaceportCup]

Last week members of the team visited @MrsWilliamsMI classroom at Mason Intermediate (@MasonSchools & @principalmesser) and talked to students about rocket science and lead a soda straw activity.

[MrsWilliams @MrsWilliamsMI]

@ucrocketry Best of the Best right here! Thank you for engaging our Ss in meaningful, real-world learning experiences! We had a “blast!” (Pun intended) 🚀 @EthanMccowan @principalmesser @uofcincy @MasonSchools @flyAmyfly

[MrsWilliams @MrsWilliamsMI]

Loved having @ucrocketry come teach our Ss all about rockets! Ss designed and build straw rockets. 🚀 Tomorrow we test and collect data! @EthanMccowan @principalmesser @flyAmyfly

I’m gonna give 10 random people that repost this and follow me $25,000 for fun (the $250,000 my X video made)

I’ll pick the winners in 72 hours

@MKBHD “Boz, Scaggs”

[Ethan McCowan @EthanMccowan]

@MKBHD Box Scaggs, “thanks to you”, has a little bit of everything and is one I use frequently
