Happy Quest for Questions Day, rocketeers!

Here at Apogee, we believe that a single, curious question can be the launchpad for incredible discovery. Customer questions have consistently led to breakthroughs, not just for the person asking, but for our entire community and even for us! For instance, a customer's query about a specific simulation setting was the direct inspiration for our recent Peak-of-Flight Newsletter (Issue #666) on using the Cd Override in RockSim-Pro.

Your questions push the boundaries and help everyone learn. That's why we want to shine a spotlight on the best place to get them answered: the RockSim Live Training stream!

Every Friday afternoon, Apogee's founder, Tim Van Milligan, goes live on YouTube to talk all things rocketry. This is your free, weekly opportunity to ask anything and everything about rocket design, simulation, and construction.

Wondering how much black powder your Katana needs for dual deployment? (Episode 190)
Trying to design a rocket with tube fins? (Episode 186)
Curious about the difference between RockSim and RockSim Pro? (Episode 164)
No question is too simple or too complex. Tim tackles them all live, using the RockSim software to demonstrate solutions in real-time.

So, bring your curiosity, your design challenges, and your "what if" scenarios. Let's find the answers together.

Join us for the next RockSim Livestream this Friday at 2 p.m. Mountain Time (4 p.m. Eastern).
