I'm becoming excited to see this launch coming up. hopefully it'll go on the planned Aug 29 attempt. I'm planning to take the kids down to see it even though school will have already started by then.

Said to be the most powerful rocket ever launched..... every time I saw the shuttle go up I thought how it must have been to see that huge rocket go up for the Apollo missions. This is a different kind of rocket so don't know how it'll compare, but still....should be good.

I just wish I had a better understanding of orbital mechanics!

I had thought about buying tickets to get to see it form the closest viewing point but by the time the my browser got me in those were sold out....just as well, would have been a lot of dollars for the whole family and then other logistical issues as well.....

Anyway, I just finished watching the press conference that NASA streamed live yesterday. This is shaping up to be very interesting. The only thing that really soured me though was that they made a big deal about equality...first woman....first person of color... equal numbers all around. Not one of the reporters bothered to ask why the fractions didn't need to match the applications or match the "most qualified".

Anyway, I'm excited. Several years ago at Airventure I saw Gene Cernan speak...basically about how sad it is that we stopped going. I really wish he could have seen this.

Get kerbal space program. And say goodbye to your free time.

Altho I’m not at ULA anymore, a little bit of the upper stage of the rocket systems ( the ICPS) has my tiny bit of software…..I’ll watch it on NASA tv.
 
I have been invited to three manned launches over the last 40 so years..and every single one got scrubbed to outside my travel window…that being said I don’t plan to be there on 29 August so your probably ok, but it’s always an issue…but we always had fun and it was part of the journey. I have attended Shuttle launches as a member of the public and it was truly amazing when those SRB’s lit off.
 
yeah, I first moved to Fl back in 94. Didn't go over for a launch for a long time because "they always cancel"...
finally the stars aligned.... weekend, a shuttle was launching Saturday AM something like 3AM....what the H... I'm going. Told a friend at work. He said what the H..., I'll join you....
it was awesome. Had no idea where to go, drove to Titusville, to the NASA causeway bridge then north on US1...found a spot where there was a trail in the woods down to the water, put our chairs there, feet in the water. wow.

Sounds like a good way to be eaten by a gator.
 
I remember watching on TV when STS-1 took off. I asked one of the other engineers at Martin Marietta Denver Aerospace if he knew what a drag race between the shuttle and Saturn V would look like (I was in high school when Apollo 11 landed). He said that the shuttle would, indeed, leap off the pad, but the Saturn V would catch it and leave it behind. Higher sustained g's once it got moving. Remember, when they lit off the engines on the Saturn V it weighed more than it would generate in thrust and had to burn off some fuel getting the engines up to full power before it could move.

"The F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed." :biggrin:
 
Just did some research...if you can believe wikipedia
this Block 1 variant of the SLS will deliver 8.8 million # of thrust at liftoff
while the Satun V had a maxiumum thrust at liftoff 7.891 million #

I suppose the big difference is the SRB's vs the liquid rocket engines. Any idea how they compare? I'm guessing the SRB's are somehow more efficient, probably less fire a drama....
still, should be good.
 
About 10 years ago a few of us mostly driven by Apollo engineers that I hang out with ( I am the only one with out a PHD in something) tried to get NASA to rename the SLS…trying to drive interest back into the program through a elementary stem students submitting a name…SLS is so lame vs Saturn V…

Actually participated in that debacle…anyway if you knew the history of US space exploration…having kids under 18 participating with winning essays or classroom submissions including a name of vehicles has a been commonplace. This was prior to Boaty Mc Boatface, but the plan was to continue the tradition. Unfortunately NASA’s priority at the time was Muslim Outreach…some would say they still have lost their way, and one of the reasons it’s been so delayed. Having grown up in this community, NASA is just as woke as the rest of our government…

The numbers varied by iteration of the rocket, but the typical thrust of the first stage was >7.5M lbs and the typical weight of the assembled, loaded rocket was <6.5M lbs. So it had a positive thrust/weight ratio once the engines were all at full power.
