Matt we don't need a bigger NASA budget. What we need is fiscal responsibility in the use of that budget; things like not giving a dime of it to companies with a decades-long history of sucking it dry and then asking for more, without actually producing what they were contracted for.

Matt we don't need a pony. What we need is a unicorn.


I thought Elon was going to give us all a pony?! And an electric one at that...

Getting rid of the useless Orion and launching the crew with a proven Falcon 9 and Dragon (or Atlas V and Starliner) would help. SLS isn't designed to launch astronauts, wasn't that acknowledged already by the Ares I?

SLS is specifically designed to be a crew rated vehicle in its final form. Initial versions of the vehicle may have some parts are not fully crew rated. For example EM-1 will be using a non crew rated ICPS (needs to have abort detection hardware and software added), Orion (ECLSS is not complete) and LAS (inert abort motor).

There is no proven crew dragon and F9 would put Dragon LAS to test a couple times now.

How much more will be spent on Orion and getting it on SLS? If it truly is redundant for a lunar mission (and I really don't see how it is) then it seems like you could make an argument for directing those funds to SLS.

Fine, SLS to LEO, NASA contracted SEP from LEO to LLO. Ukrainian hypogolic lunar lander. lunar modules made by Bigelow Aerospace. Talk with Russia and ESA to determine where to land, and which scientific missions to focus on.

in 8 years some work for a full-time outpost could be set up remotely. Maybe not ISRU, (although that should be looked at as well) but possibly the supply caches, equipment and even some excavation work for a moon base. It might be worth revisiting ideas from Project Promethius to have a compact reactor in place.

You are confusing Ares V with SLS. They are totally different things. SLS is designed to launch astronauts, just the delta IV-derived underpowered upper stage of the first launch is not crew rated, all the proper later upper stages will be.

A Note is that the EUS has only passed the PDR in Jan 2017 and not yet made it to CDR meaning only the outline and requirements exist not the detail design. CDR is not usually any sooner than 6 months after PDR for complex systems. EUS CDR is likely to be next year or even later in 2019. After CDR it should not take more than 2 years to build the first flight EUS. Putting it ready by sometime in 2021 for acceptance testing.

But indeed one of the baseline requirements is that it be designed to Human Rating standards.

So at the moment the LV for EM-2 is still being designed and once the stage is designed then the pad and VAB changes must be designed.

Just because SLS is designed to carry humans does not require that it be used that way.  All the safer for those expensive unmanned missions to Europa, etc.
