Seriously? So NASA is re-inventing rockets because rockets exist? SLS is different from any other rocket designed, with exception of NLS (which was never built due to budget cutbacks)..
I'm sorry, but I am really GD tired of everyone being critical of NASA... Seriously I try to love my job, to feel like I'm working on something special, but time and time again everyone trashes NASA. And then they play up SpaceX, who has produced two launches, neither of which has worked as advertized. At least no one complains about Army missile work... |

Its a Saturn V with two SRBs strapped on, both of which can be seen at the space MUSEUM on I-565. Combining 1960's technology with 1970's technology is hardly anything new. And they say it will take SIX YEARS to develop and cost $36B; which means it will really cost $72B, or more. We scrapped the Shuttle for this?

Saturn V is LOX/RP1, using the F-1 engine
This is LOX/LH2, using SSME's that we already have and can actually make (can't make F-1's anymore) We scrapped the shuttle because it's extremely complex and expensive to operate, and would have likely resulted in more deaths. You go write your congressman that you want NASA to develop new engines and new materials, but you better be able to find a way to get more money as well. Everytime NASA gets asked to do something new, 2-4 years later politicians cancel it. We control the politicos, so we have no one to blame but ourselves for this situation. |

Adding on to what Mac said, they aren't Shuttle SRBs, they are the RSRMV SRBs developed for Ares. These are bigger, 5 segments instead of 4, with reformulated propelant which macks them much more powerful. And with reformulated insulation that makes them safer.

I agree that political decisions damage NASA, but hey, that ain’t nothing new. It’s been that way since JFK. All Gov’t agencys deal with that; NASA ain’t no different. NASA faces many problems for its manned program, but the biggest is that all the low hanging fruit has been picked and they don’t have an achievable long term goal. They have done the low earth orbit manned stuff and have done the man on the Moon thing. There are no new easy and affordable manned missions left which are worth doing. A manned mission to an asteroid? Why? Asteroids come to use every day. Manned mission back to the Moon? Been there, done that, bought the t-shirt…….. Manned mission to Mars? Two orders of magnitude more difficult than a manned moon mission and with the economic future of the US, there will never be money to fund it. IMO, the focus should be on quickly redeveloping the US’s capability to carry men/supplies to the Station, HST II and un-manned robotic missions to the other planets and their moons. That behemoth that Bolden rolled out is a pieced together junkyard rocket without a purpose. |

Done them? I think they just proved that they are doable. I think that we should be looking at establishing some kind of outpost on the moon, and we should be looking at serious solar collection (and weapons) by placing some big-ass mirrors outside the earth's atmosphere and beaming energy or Taliban-frying lasers back down here.
Easy? I agree. Affordable? What is affordable? Can we afford NOT to do it?
If Magellan had felt that way, we'd be speaking Portugese now.
Done what? All we did was prove that it was possible to get there and walk around and drive around and get back, largely intact. Now the real science can begin. Lets build a permanent minimal gravity facility there.
Agree.
Isnt that what this new proposed lift vehicle would do?
Maybe that's what Obammer told him to do!

[/QUOTE] That behemoth that Bolden rolled out is a pieced together junkyard rocket without a purpose. Except it can lift 5 times as much as the Shuttle, and 35 tons more than the Saturn V. The decision to use solids vs liquids is still up for debate (my understanding). They will be using Solid Rockets at first to test the System because they are available. The one good benefit is Boeing is doing alot of the conceptual design work, which will hopefully prevent some terrible decisions in the past. I dont necessarily agree with NASA's approach all the time but its nice to see something that might work (unlike Ares which was a political stunt from lobbyist) I have alot of friends that rely on keeping NASA alive in Huntsville (including myself), Marshall will only be around if they build another launch vehicle here...
