Thank you Pugsley69!
PUGSLEY69!#@#$@#@!#@ Thankyou #$@!#@$@#! I was so worried I wouldn't be able to find out exactly what type of rocket this would be! Much love! "The Internet Provides All."
After a big of digging around i found out its a RL10 hydrogen fueled rocket. Its being developed as a Common Extensible Cryogenic Engine or CECE. Its a rocket designed to be used for Deep throttling, or landing a spacecraft safely and precisely. Due to the fuel type its capable of firing from 104% thrust down to 5.9%. Which allows for a lot of control of the rockets power.
It's lower end of Gas Nozzle.
looks awesome, whatever it is.
I don't know what this is, but I like it.
