Josh IN SPACE Posted January 11, 2018 Share Posted January 11, 2018 Perhaps ZUMA is a reference to Montezuma II, of Tenochtitlan? Come on FH static fire, let's go. Quote Link to comment Share on other sites More sharing options...

sh1pman Posted January 11, 2018 Share Posted January 11, 2018 Is prop load that big of a milestone? They just pump RP-1 and LOX into the tanks until they're full. Quote Link to comment Share on other sites More sharing options...

Yeah, it is. They are testing all the propellant loading gear for 2 extra boosters that has never been used before. Quote Link to comment Share on other sites More sharing options...

Whilst I understand prop loading is a big milestone, surely the whole point of the Heavy is it’s easy because you just get what works for the F9 and add 2 more exactly the same. Should almost be mundane by now surely? Edited January 11, 2018 by Jaff . Quote Link to comment Share on other sites More sharing options...

What if there is debris in the fuel lines, etc, etc. Quote Link to comment Share on other sites More sharing options...

So take any racing pit crew and tell them "okay, now instead of doing one car at a time, we're going to bolt three race cars in tandem, and you can change the tires and refuel all of them at once."

Having been present at the first launch attempt of EFT-1 and hearing that there was a fault with the Delta IV's fuel valve (wouldn't shut iirc); I personally don't think they can test fueling enough.

Undoubtedly, one of the things they learned is that there are many more "thats" which they don't know about, and every time you change something, and even if you don't, those "thats" can creep up on you. Remember, there are millions of things that can happen to a rocket, and only one of them is good.

It's just that the explosion is supposed to be forced out the bottom rather than expanding outward. Quote Link to comment Share on other sites More sharing options...

Green Baron Posted January 11, 2018 Share Posted January 11, 2018 Just guessing: the NASA dates are for the certification flights, everything should be ready by then, but the companies can undertake private flights if they like/can afford/don't damage too much ?

It's not Starliner, I bet it's LV certification. Atlas V is already man-rated. F9 requires 5 block 5 flights to get a certification.

Getting the payload into the correct orbital position is the outcome that's required. Whether or not they get a flight-proven first stage back means that there are shades of good. (Still vastly outnumbered by the number of possible bad outcomes) Edited January 11, 2018 by Damien_The_Unbeliever Quote Link to comment Share on other sites More sharing options...
