SLS is already obsolete.  The entire thing needs to be shitcanned (again) but this time forever.

But I guess they need to test fire their 50 year old rocket engines to get the rust out of them.

Cancelling the Constellation program was the dumbest thing they ever did.

S/SH is easily 5-10 years from operational human flights.  Especially with that 'we're going to catch the booster' idea.

Catching the booster has zero to do with human safety.

Hold.  Might fire later, maybe.  Check back and see if it's been lit or not.

I love how it still "costs" over $100 million per engine to build something that was designed in the 1970s.

Meanwhile, Musk claims that it costs about $1 million to build a Raptor engine.  Granted, Musk is probably lying exaggerating, as he often does, but even if he is wildly exaggerating by a factor of 10, the Raptor is still going to be more than 10x cheaper to build than a RS-25.

Doesn’t surprise me at all that an engine designed in the 1970s would cost more than one designed for more modern manufacturing methods.

Ares V was cool, and I wish they would have stayed with that program.  The problem with SLS is not the concept per se - it is the grotesque incompetence on the part of NASA and the main contractors in implementing it.  It should have been cancelled as soon as it became apparent that they were completely unable to keep costs under control - especially since that was the rationale for the cancellation of Constellation.  The entire reason to just re-use old technology and re-use existing equipment was to save money and time.  

If SLS could have been built on schedule, and on budget, it would obviously still have been old tech (and the approach of just throwing away half a billion $ in engines for each launch is insane) - but it could still have been a reasonable stop-gap approach that could have been realistic for the short term.  But given just how ludicrously expensive it has gotten (is the launch cost up to $2 billion per launch now?) that train has left the station long, LONG ago.  

Had they cancelled SLS, they should NOT have started development of a new system.  NASA and their contractors have demonstrated how mired they are in a completely unrealistic outdated and financially unsustainable model.  Instead, they should have adopted the principles of the Commercial Crew/Cargo programs, and partnered with commercial vendors on specific cost contracts to build the hardware, specifying the mission goals and specs, but not the hardware itself.

SLS under Obama and under Trump are almost night and day.  Though it doesnt help that weather, manufacturing mistakes, and a pandemic hurt the program.
Under Obama they not only had no deadlines they had no real mission so they did things VERY slowly.  With deadlines, a mission, etc, things have been moving much better.

Core 1 had a welding issue so they put it to the side to be repaired later and core 2 was then built (Artemis 1).  Other delays are damage sustained due to hurricanes and the Green Run was delayed due to the pesky WuFlu.  Had Obama and his administrator actually created a real goal/deadline like Jim and Trump did we would be talking about launch number 2 or 3 right now of the system.

When I first heard it, I thought it sounded goofy - but when you look at just how ridiculously accurate SpaceX has gotten in landing Falcon cores, and how accurate the SN8 prototype was (even without directional thrusters, and just using the engine gimbal) when it was coming in for its (crash) landing , I am not even very skeptical any longer.  I bet they can figure it out pretty quickly.  
View Quote

Figure out what , how to land it without it blowing up ?

What was it , 6 or 8 months ago that fanboys were gloating that Starship(s) would be doing orbital flights THIS MONTH ?
Does SpaceX not have to build and test and make reliable a booster first before it gets a Starship in to space ?
Maybe a reliable Starship should come first , Yes / No ?

They have along way to go before they get that glorified grain silo in to space and it would not shock me if Artemis beats them to it.

The disassembly before flight is not true, fake news.

I agree completely.

That said, if the Starship program had been handed $20 BILLION and had been handed free engines that were already fully developed (and all of the previous Ares development), and given ten years of time - I am pretty confident that Starship would have landed on the moon by now, and would probably be well on the way to Mars.

Artemis will be neat - but the costs have been completely ridiculous, given that we are talking about merely replicating something we already did 50 fucking years ago, and doing so using proven an existing technology (and in fact re-using a bunch of parts sitting in warehouses).

The last couple of times that my wife and I have been at KSC, it's almost sad to walk through their displays.  It's like it's a history museum, with an homage to the past ... and then some wishful thinking and fantasies about what they would LIKE to do in the future, but you know it's never going to happen.  It feels like NASA is just this old geezer in the nursing home on life support, reminiscing about the good old days.
