THE FIRST 3D
PRINTED ROCKET

Relativity is scheduled for its second launch of Terran 1, called "GLHF" (Good Luck, Have Fun), from Launch Complex 16 in Cape Canaveral, Florida. Our launch window opens at 1300ET on March 11th, 2023. This launch of Terran 1 by Relativity will not include a customer payload.
As a two-stage, 110ft. tall, 7.5 ft. wide, expendable rocket, Terran 1 is the largest 3D printed object to exist and to attempt orbital flight. Working towards its goal of being 95% 3D printed, Relativity’s first Terran 1 vehicle is 85% 3D printed by mass. Terran 1 has nine Aeon engines on its first stage, and one Aeon Vac on its second stage.
Like its structure, all Relativity engines are 3D printed, and use liquid oxygen (LOX) and liquid natural gas (LNG), which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars.

I thought this was very interesting. I hope they are successful. 

That is interesting since 3d printing could help in some ways with heat shielding. 

Range is cleared
 
go at 14:42  EST to continue count down from 00:01:10
 
 
& HOLD @ 00:00 engines were on
 
checking vehicle health Now .... see if today can happen
 
"launch recycle" countdown clock reset to 45:00 - & holding
 
countdown has restarted
 

 
 
they are @ 00:30:00 and counting
 
 
 
 
 

 
That is sooo stupid. Start a 45 minute countdown and not one person checks and realizes that the permitted launch window ends in 44 minutes. Wonder how many millions of dollars that mistake cost them.
 
 

Third try they got it launched, around 1:20.

Unfortunately, the second stage rocket didn't engage for a failure. Hopefully they can get that fixed since it's interesting that it's 3d printed.

I assume more attempts will be made until they get it right.
