An 85% 3D-printed rocket just made it through Max Q & survived

Relativity Space just successfully launched its Terran 1 rocket... a test rocket which is 85% 3D-printed with the goal of getting through Max Q or the time of highest atmospheric pressure on the vehicle to see if it could survive
And the test was a success... with the rocket getting through Max Q all the way to main engine cutoff (MECO) and first stage separation before the second stage failed to fully light and unable to reach orbit.
However... getting to MECO & stage 1 separation is a huge success for Relativity Space... just proving a 3D-printed rocket can survive Max Q.

We are fricked.

I thought it was scrubbed? I had a thread all typed up at 9:45 and the live feed said it was scrubbed for the night?

But could it make through Max Hardcore? Doubt it.

I googled "Max Q" and quickly reminded myself why I went into ISDS instead of engineering.
I THINK I get the concept now though.

they held the countdown several times throughout the evening... but the rocket did take off tonight

"Max Q"
Think of it like when you are trying to stick your dick into something. There is that initial physical resistance right before it breaks through and everything starts to slide easily the height of that resistance is Max Q and it is the point you are most likely to break your dick.

The implications of this are..... well..... I will let the experts chime in on this one.

In other words, before reaching max q, the dynamic pressure increase due to increasing velocity is greater than the dynamic pressure decrease due to decreasing air density such that the net dynamic pressure (opposing kinetic energy) acting on the craft continues to increase. After passing max q, the opposite is true. The net dynamic pressure acting against the craft decreases faster as the air density decreases with altitude than it increases from increasing velocity, ultimately reaching 0 when the air density becomes zero.
Sounds pretty simple to me

Yea buddy!
That shite makes perfect sense to me now! now.
Hell they should hire me to help em bust that "Max Q"

This is all I am going to think about when my wife lets me have sex with her next year.

Good news. Now your mom can start 3-D printing her dildo.

Good luck, have fun!!!

They have a dozen jobs open in S Mississippi at Stennis. Also another company called Rocket Lab is going to build rockets here as well, theirs are carbon…so plenty of work if y’all are interested in that field.

First stage survived. Second stage not so much.

Second stage not so much.
