MAN 2021 is going to be a fucking abso-fucking-lutely trash year.

This is my primary reason for liking it, I firmly believe that aerospikes have greater potential than the few testbed engines built, and Venturestar's XRS-2200 was by far the furthest along in it's development. Uprating and modernization using computer design and manufacturing might have led to an actual improvement in performance over conventional deleval engines, but now we probably won't know for decades.
Instead we get SLS, yaaay...

Is there anything SLS can do that Starship Centaur V can't do better?

>>12090059
OH NO NO NO NO SLSBROS.
Literally all Elon would have to say in reply to this is "Hey, my rocket has already flown, where's SLS?"

See this is why competing companies should always be courteous to one-another even if they hate one-another's guts, because when you slag someone off as a "pot smoking weeb" and then your joint Chinese/Indian coded capsule tumbles itself because the software you've written is shit and then NASA, humiliated by your extremely public failure forces you to completely re-do the test, it looks extraordinarily bad. Especially if the "pot smoking weeb" dude then beats your company to a safe, perfectly executed manned mission in a novel capsule developed at a fraction of the cost and time that yours was.

The ABSOLUTE state of Boing!

I know, it's a real shame. The Pyrios boosters would have actually created a reason for SLS to be used in favor of any other competitor too, because out of the gate they would have given SLS a 150MT lift capacity with another 20MT on top after uprating. At that point you could have even made a valid argument that SLS still has a purpose because using the Pyrios boosters it could launch up to 170 ton single piece large payloads.
As is, with S(hit)RBs it's got subpar lifting capabilities considering it's size, cost, and manufacturing cycle time, basically unjustifiably anemic especially with the absolute dogshit Interim Propulsion Stage, since the fucking Yuropoors can't get their shit together and deliver the Exploration Propulsion Stage anytime soon, just another reason why collaborating with other """countries""" is just going to cause more stagnation in the space industry.

It's more that we're not going to be backsliding (unlike what's happened with a certain human spaceflight program). A viable ISS replacement will be in operation contiguously with ISS, starting as some additional modules and then continuing separately.

I've stayed out of the argument about Boeing shilling that's gone on for the past few days, I'm just pointing out that if you want to avoid shitting up a thread it would be a good start if you stop namefagging for no reason. Attention whoring is in and of itself a form of shitting up the thread.

Never flown either but I'm fairly sure considering the number of crashes that it's safer to fly a helicopter compared to something like a harrier. In general helicopters are better at VTOL compared to jet aircraft, they don't have to deal with hot air ingestion as much.
>>10994275
I said components, not an entire vehicle which does nothing. SLS is unique in that regard.

Mr. Bridenstine, I don't feel so good

I agree completely on the technical stuff, the parts are not the issue (except those fuckin SRBs, FUCK SRBs), I'm sure they'll all perform as optimally as they can. I just think they've been configured in the wrong way, high ISP SSMEs would do better work at least higher up in the atmosphere and after leaving it where they're hydrolox propellant can develop more of it's desirable properties. The orange tank is fine too, it's done it's job just fine. The fact that the parts are being utilized in a sub-optimal way directly supports your own point about bad management. SLS is a slap-dash vehicle and things like it aren't made unless the people in charge of planning don't really know what they're doing or aren't designing it for the right reasons. I don't think it's good to build a space vehicle with NASA's limited funding just to burn up excess parts and all of it's missions will suffer because it was built to expend shuttle parts first and do everything else second.

IT'S MADE OUT OF SPARE PARTS

DON'T GIVE A FUCK IF MY BUDGET IS BLEEDING!

>It will exist as long as SLS does.
That doesn't bode well friend.

Yeah but that's been the trend in political behavior for at least half a century.
>>10629978
That sounds great in theory but then you'll remember that the President would be a democrat and all promising projects will get canned for arbitrary reasons that could easily be solved without political intervention and the budget will be both slashed in half and redirected to transgender muslim outreach.
