Hi Mr. Bruno! Thank you for doing this AMA!

I'm a student interning for a big partner of ULA's, still deciding on a career to pursue, and was wondering what fields you foresee being big influences on your industry in the coming decades. Are there any big technologies in early development that you think will have have a large impact on space travel down the road that would be well worth getting involved in now? Thank you!

What's it like getting to work with rocket engines everyday? Being as complex and as mission-critical as they are is it more tense than some other aspects of SLS or is all the more exciting? And with the RS-25 being an older piece of hardware does it ever pose any quirky challenges? And lastly, how did you get involved with the propulsion engineering side of spaceflight? Thank you!
