> But also NASA landed two SUVs on mars first try, using skycrane, Full remote. they developed and built mars helicopter/drone (rip). First try. But spaceX gets the glory because... break things??

NASA lost a good number of probes in the process of getting the expertise to do that.

And likely quite a few test devices in building out the skycrane.

You cant be making shit up and equating a test to blowing up 7 rockets

wtf does that have to do with Curiosity program? All of these are 2+ decades old.

Besides, you make it as if SpaceX couldn't learn from nasa mistakes, not to mention core team of SpaceX are ex-nasa already.

what kind of elon musk logic is that?

That’s 20 years of learning how to design and land things on mars. They wouldn’t have been able to build Curiosity without the past experiences. The Curiosity program itself started in 2002, just a couple years after the missions above.

What people say is that knowledge in the field is extremely hard to transfer, and easily lost. As an example, apparently we are completely unable to rebuild the Space Shuttle and Saturn rocket, even though technology is vastly more advanced today. Each vehicle really is a “program” including all its people and supply chain. This is also something SpaceX is trying to change by building actual production lines for their engines and bodies, not one-off builds.

So you are saying that Curiosity team had probably not learned anything from those 20 years old programs?

You are literally strengthening my point...

▲ricardobeat 3 months ago | parent [-]

No, that’s about “SpaceX learning from NASA’s past mistakes”. You also don’t seem to get the point that they were 2-year old programs when Curiosity started, so I’ll just leave it here.

▲me_me_me 3 months ago | parent [-]

Yeah leave it here. You are probably tired after moving the goalposts so many times.

▲ricardobeat 3 months ago | parent [-]

Please don’t play these games on HN. A few of these threads will get your account flagged.

It was a single comment, how can the goalposts have moved “so many times”. You made no effort to engage on a reasonable discussion, and made a smart-ass comeback with something I did not say instead, it’s simply not an interesting conversation to be had.
