On the plus side, this means we'll get another round of "Go or no go"....my favourite part (apart from the actual launch of course)...

Maybe some kids will get to watch the launch live at school now at least, if schools still do that sort of thing.
 
Don't get your hopes up - in it's current form, a SLS based manned mission to mars is probably a pipe dream. Let me explain:

1. You need a large number of SLS launches for a human mission to mars.
NASA currently has neither enough budget nor enough core production facilities .

2. SLS launches are very expensive, and much cheaper alternatives could be available soon.
SpaceX prepares for its first falcon heavy launch mid 2015, will have 2/3 of the LEO payload of SLS Block I for 1/10 of the price.

3. Private companies can develop super-heavy lift boosters too, and they could be ready far in advance of SLS Block II.
SpaceX is currently developing a new engine called Raptor for a new booster. It has a far higher payload target than SLS Block II, and they plan to be ready more than a decade earlier - without government funding.

(other companies are developing new engines and boosters too)

I'm in favour of human missions to mars. But do you think the senate will continue to fund SLS once much cheaper alternatives are ready and available?
Fixed price contracting like what NASA uses for the commercial crew program makes much more sense.


The SpaceX Dragon V2 looks pretty sci-fi-ish -
that's because it's missing the inner lining.
2024/2025 if Mars One happens.
That's an enormous "if".

Do you see a competitive market developing for a mars mission?
Honest question, I'm not an expert on the economics of space travel.

In my very not expert opinion, I think the most that you can hope is like the situation you have in air force jet fighters, when very small numbers (read:2) of bids have to assume a huge r&d risk (or get paid for that by the government). I wouldn't say the next gen jet fighter has been an extremely efficient or cost effective story.

In any case, I think first phase space exploration should be publically funded (though of course, the private sector always plays a big part of it), it's a high risk, long term investment that is problematic for a for profit company, but ideal for the government.
And we can totally afford it, there's no reason not to go all in on mars.

Today I learned my productivity goes way down when I have a livestream open, even if nothing is happening on the stream.

What do you mean nothing happens?

Lock at that shit, action packed!

p.s.
It's probably just me, but it looks like we're flipping the bird to space.
Fuck you space! we're going to make you our bitch!!

I could watch that all day.

In fact, I have been watching that all day.

I've got a feeling they're not going to resolve it and the launch is cancelled.
Most people may realize that. I just wish they would confirm it now so I could try to sleep instead of waiting another half hour. (Since clearly, the space program should cater to my sleep schedule)
 
Will this be able to replace the Soyuz for US needs, in case the Russians decide to deny use of it?
In theory, possible someday.
In practice: Way too expensive, other US vehicles ready much earlier. ISS might not even exist anymore.

Without sufficient government or angel investing, not until we already have a mars habitat, if then. With either, sure.
And we can totally afford it, there's no reason not to go all in on mars.
I'm criticising SLS, not government funded mars missions in general.

SceptiMatt is in accurate name!
Thanks, I guess?
We don't know that. They could in fact be named Mark instead of Matt. Or maybe even Lucy!
My name is in fact Matthias
