@jeovannijuarez9518 who is having trouble understanding that NASA and SpaceX are partners on the ISS supply and crew flights?
What's being talked about here is the NASA mission to the mars which is via SLS, compared to the SpaceX mission to mars which is via Starship.
NASA has nothing to do with Starship, so that's not a partnership (though NASA will probably buy into Starship later, when they realize how far ahead it is)
And yes, the astronauts on Dragon are from NASA, because they are the paying passengers on the rocket, which is why NASA gave SpaceX any money.
Now, that said, SpaceX would not exist without NASA having hired them just before they went bankrupt, and they have worked very closely for years now, trading engineers, giving each other full access to their designs and knowledge, and they really have been working as partners, and they are years ahead because of the NASA support, but that doesn't mean that they aren't still going to beat NASA to Mars by a long shot.
Though probably by then, NASA will have bought tickets and sent one of their astronauts along lol

@Ellivation the non perishable items Costco has are generally available elsewhere too, but generally if I am comparing whatever Costco has to what Walmart offers, usually Costco has better.
Walmart doesn't care if they sell crap, and so they sell a lot of it.
For an example, between working construction and having horses I buy a lot of garden hoses, and Costco only gets the best.
So when they have them early in the year, I buy whatever I need, and they last better than pretty much any other hose I have gotten elsewhere. Now, I could spend a lot of money and get a "professional grade" hose, but that adds up when you need a bunch for horses and gardens, and the low priced Costco hose works just as well.
They only carry the best windshield wiper and. The car batteries are excellent, as is the warranty, I try not buy car or truck batteries anywhere else.
The food is always top notch, produce, etc, while other stores it's hit or miss if they get a good batch, if Costco has it I know it's going to be good, and on the rare occasion where something is bad, I can get a refund the next time I am in even if it's two months later and I don't have packages or receipts lol
Some things, cashews and coconut oil specifically, Costco has literally the best available.
They sell so much of both of those, they have incredible buying power, and so demand the highest quality that the growers produce. I think they still sell the majority of the world cashew production, and they are pretty high on coconut oil too.
And again, if I see it in Costco, I can trust that it's been tested and vetted by their buyers, and has a higher chance of being a good product than something I see on a Walmart shelf.

@jeovannijuarez9518 guess who trained the NASA astronauts on all the systems involved in the launch and operation of the capsule? And where that training was done?
Hawthorne by SpaceX.
The space station training was done by others, because that's not SpaceX technology, but anything SpaceX builds, it's going to be doing the training for.
And when SpaceX builds a rocket to Mars, it's the only one who will be able to train the astronauts to fly it.
And remember, Boeing has their own astronauts, one will be flying on their first manned Starliner flight along with 2 NASA astronauts.
Training astronauts is a specialized program, and has to be down by the people creating the technology, so even if NASA employed astronauts fly on Starship, they will have been trained by SpaceX, so SpaceX can train their own just as easily.

@commonsenseskeptic yup, a successful landing but with a sticky valve is such an insurmountable problem! Might as well scrap the whole thing.
Back in reality, Elon has said that they gained enough data from that launch and landing to focus on preparing for a full stack launch, and so instead of spending more time and energy on hops, everyone is working on integrating everything for the orbital launch.
If they still had things that needed hops to test or figure out, they would be doing more hops, but once you reach the performance goals for that stage of testing, why keep doing it?
Of course you are a dedicated negative viewpoint, so you see any changes to the plan as proof of failure, when they are actually signs of optimism and success, that the team believes they are ready for an orbital flight on the next launch.

While it is true that hemp and bamboo grow in height faster than trees, they require much more care, better conditions, and it is harder to get the volume that you get from tree farms.
Tree farms can cover thousands of acres of wilderness, requiring no care beyond the initial seedling plantings, and thrive in areas where you can't grow bamboo or hemp.
Pretty much any hemp grown is directly displacing some food product that was being grown there, and requires the same kind of machinery and irrigation and tending as other crops, for much less yield per acre.
And yes, trees take 20 years between harvests, but when you are running thousands or millions of acres, rotating through, you always have some ready to harvest, and when you harvest a section of timber, you get many times more fiber than anything else, including bamboo, because bamboo is hollow, while trees are solid.

I haul a lot of the giant paper rolls out of some of the Georgia Pacific paper mills, as well as some others on the west coast, and deliver it to several GP and Westrock and PCA box plants down throughout California, as well as hauling recycled cardboard bales to the mills, and delivering to Amazon Fulfillment centers, and I am a Prime member, so this video has a lot of familiar sights in it! Lol
Most of the boxes that I see being produced in California, and this is not surprising, are for food related products, produce, etc, but at least one of plants I regularly go to (westrock in the bay area) has a dedicated Amazon box line.

@dudeman8989 ummm, share cropping means that a grower contracts with a farmer to grow hemp on their fields, for a share of the crop. This means that the farmer will stop growing whatever they had been growing, usually food, and grow hemp instead, thus displacing a food crop on prime fertile ground.
And if the hemp is not being grown in fertile ground, then more fertilizer is needed to get it to grow.
Also, generally speaking forestry replantings will usually only fertilize the new seedlings when planting them, and then only in poor soil.
Once they get roots down and start dropping needles, they actually improve the soil fertility since they bring it up from deeper then other plants get it.
I rarely ever hear of anyone spraying trees, especially not coniferous trees used for making paper.
So your arguments don't stand up to facts.
Oh, and hemp would use a lot more pesticides, but very few pesticides are currently approved for use on hemp because it hasn't been tested and added to the label yet, so it can't legally be used, especially not for any grown for human use. Once the companies get the testing done, you will see a lot more pesticide being used.

@jeovannijuarez9518 oh, you are right that NASA is more experienced at training astronauts, and so I fully expect that when SpaceX begins their training programs for the Dear Moon mission, and whatever other missions they want their own astronauts for, that they will make a deal with NASA for use of their facilities that don't need to be specific to SpaceX equipment, and that NASA astronauts will be involved in the training program, supporting the SpaceX staff.
Or maybe SpaceX will just hire NASA astronauts like Bob and Doug, people who have all the NASA training and experience, and also understand SpaceX well, and have them set up the training program.
And for missions to the ISS, even just tourist missions, Tom Cruise, movie crews etc, part of the training will occur at the NASA ISS training facility, and maybe some at the Russian ISS training facility, and if they are going to be doing any evas, they would probably use the neutral buoyancy facility, but SpaceX can get access to all of this as a customer, and do the training themselves, except maybe for the ISS specific parts.
And considering that all the NASA training stuff is decades old, as is their training program, I would expect to see SpaceX developing new EVA space suits, in which case, building a swimming pool and making a new neutral buoyancy training facility for the new equipment isn't very expensive, and for anything to the moon or Mars, there isn't much that NASA has that would be applicable to the training, but anything that it does have, SpaceX would have access to.

@Rommie26 no. Lol
Roads have to support the weight of traffic, handle extreme temperature swings without falling apart or buckling up, and most importantly, provide good traction for cars.
Asphalt does all these great, gives the best smooth ride, can be made porous so rain doesn't puddle on it to increase wet traction, and is flexible to allow use on softer sub soils where the road flexes under heavy loads. It is cheap and easy to install, and can have more layers added on top to renew its surface.
Concrete is much more expensive and labor intensive to install, and never gives as nice a ride as asphalt, but it lasts a few years longer before full replacement is needed. As concrete ages, it begins warping, which makes the ride worse and worse over the years.
There is really no other technology or technique that would survive the conditions and make a safe road surface.
