If it allows us to own a huge new tax generating industry...that can't be all bad.

Ok - snark aside, what's the value proposition of this new industry?

I was wondering the same thing. There doesn’t seem to be any market. It’s not tourism. Even orbital tourism for us plebs is decades or more away. There are no resources worth mining on mars. You can’t claim land. You can’t do ****.

The only thing where there’s a possible market is asteroid mining. But we’re 100-500 years away from resources like nickel, iron, and other non-precious metals becoming scarce. Much less be profitable to mine off earth.

At this point, it’s just a big dick-measuring contest between billionaires

Space has always been a dick-measuring contest... This isn't new...

They need to build and operate a deep water habitat before they ever go to Mars.

I'm not going to get into defending the concept of space...cuz I don't care and I only get into it if I know the topic thoroughly. But I'll give my opinion on several aspects of this.

First, if we're going into space I would personally rather see this private than public. It would cost a horrific amount of taxpayer dollars that could be used more productively on earth. Of course, NASA would need to be there to regulate, etc.

Second, the value prop is not for me to decide. If industries see one, they'll invest - which is probably as it should be. The several potential value props are raw materials, improved energy, tourism and a technology halo (the last of which is not likely a positive for society).

Third, if space travel happens and we're the leaders...there will be significant wealth and technological innovation benefits.

Fourth, if we do pass which I doubt...then others will go into space. The Chinese will be there in 20 years regardless of what we do. We may live to regret that.

SpaceX makes it 3 launches/3 landings on its latest booster.

Not bad.

Can't do sh**? Says who? The International Space Treaty of 1967 is a gentleman's agreement waiting to be broken once valuable resources are found. A technical loophole exists in that those responsible for items in space have rights to the territory surrounding their spacecraft (ie: the land around the Apollo landings is US territory.


The issue though isn't with mining asteroids, Mars, or the Moon, for precious metals or other resources to bring back to Earth. The idea is to use these short stops of resources as a Celestial Sunoco station for points beyond.

If you're routinely travelling to Mars, why lug a giant tank filled with your supplies from Earth. Have enough to get you to the Moon, fill up with the resources (potentially found on the Moon if there are any), and be on your way again. Lower weight launches requires less fuel to move that weight into space.

Asteroid mining could take place with the resources mined being housed on the Moon. 1/6th gravity makes landing/take need way less fuel than bringing it all the way to Earth.

So in summary:

1) Launch a handful of horrifically expensive, subsidized, experimental rockets

2) ???

3) Significant wealth

It was more believable when I heard it from the underpants gnomes.

Pitching commercial space exploration to investors should be as illegal as pitching Ponzi schemes or perpetual motion.

(snark back on, BTW :) )

There was gold in the New World, too. There were even companies formed to get that gold. Some failed and some had a marvelous ROI.

But, then again, so did piracy.

SpaceX blew the landing. Landed in the ocean just short of the Cape.

3 things of interest

1. New Horizons made its rendezvous with Ultima Thule on the 1st. First picture shows a rust colored snowman shaped object.

2. China landed a probe on the far side of the moon. They're using a satellite at the Earth-Moon L2 point to send the signal back

3. SpaceX has rolled Crew Dragon out to Pad 39A. The unmanned demo flight will be later this month.

4. OSIRIS-REx is orbiting the asteroid Bennu, surveying for a good place to do a biopsy.

This is an incredible story and I hope all of it comes true.

First, that's really cool. I hope that tech makes its way into common use sooner rather than later.

Second, what are the downstream consequences? It seems like a good way for some third-world nation to start yet another deforestation project into order to capitalize on more agriculture land on these sugar-rich plants.

In response to #2. That appears to be one of the major problems. We need to do a better job on preventing deforestation. I'm not studied up enough to know the answer.

But, for example, this appears to be directly related to algae and some of the stuff that was done there? I would imagine if it all could be algae based that would be easy enough to produce in mass quantities and cheaper than ripping forest down. Just one idea.
