Anybody else watch SpaceX blow up
Jan 19, 2020, 4:13 PM
|

their Falcon rocket this a.m.? It was a test of the Dragon crew capsule's escape abort system.
It seemed to be succesful, so the USA is now back in the business of putting astronauts in outer space again..probably in a couple months.
Since privatizing space, the whole launch thing has become safer and routine. There are now hundreds of conpanies that are launching and recovering rockets. Pretty remarkable.

There are also companies putting this amazing little satellites in space for private use. Whats scary is even ISIS and Al Qaeda will have satellites soon.

I'll send you an 'Anti Satellite' installation kit for your home. But Wait! There's More! For an additional $4.99 you'll also receive the 'ASIK' for your car or boat as well!

Yep. I’m very interested to see how they and the other private companies do. I’m most interested to see if they actually have the guts to go beyond what the NASA moon missions accomplished or if it’s all just talk. I’m skeptical since there is one thing you can always count on with the business world; it’s all about the bottom line (but still hopeful).

Two HUGE problems going to Mars
Jan 19, 2020, 4:52 PM
|
|
One in a weightless environemnt humans lose a lot of muscle mass. Astronauts on the ISS have to work out 2 hours a day and still they lose a lot of muscle. About a year is the longest any humans have made it. It takes 9 months just to get to Mars.
The second major problem is radiation. The ISS is protected by earths magnetic field. We have no radiation shield yet that would work. We are decades from figuring this out.

Those aren’t trivial problems to overcome either.
For muscle deterioration there’s at least a line of sight to managing that. For radiation exposure, not so much. One of the ways they may solve it on a Mars colony is to not solve it, but rather hide from it by building a subterranean colony.
That doesn’t address exposure during the trip though. I haven’t heard of any commercially available solution to that save a giant chunk of metal at the ### end off the ship to deflect it.

I thought that the problem was bone density rather than loss of muscle. Muscle can be addressed. Bone density is a tougher issue.

The privatization of the space industry and the innovation it’s provided is directionally reducing the cost of space travel. With a lower cost structure in place, the next big challenge is to figure out how to monetize space travel/tourism to create an economically sustainable industry.
Beyond that, we’ll need to identify and capitalize on further opportunities to derive more value from space travel which in turn would justify bigger bets in the industry. For example, are their planets/moons that possess rare earth elements that would justify harvesting them? If that pans out, it would further justify more costly and riskier exploration of our solar system.

But what did the moon landing accomplice other than spending a butt load of taxpayer money ?

https://en.wikipedia.org/wiki/Solar_Orbiter
She is a contamination control engineer for ULA (her title is actually rocket scientist 1) She is responsible for making sure the rocket does not contaminate the spacecraft during the launch. Secondly, on NASA missions they are required to protect the solar system from earth bacteria etc (planetary protection)
It launches in a couple weeks.

That’s gotta make you so proud as a father.
I recall a special recently on NatGeo(I think) on that aspect of NASA missions. If I remember correctly anything that leaves orbit essentially goes through a clean room, is sterilized, wrapped, loaded, and unwrapped prior to launch.
I guess the concern is that 50-yrs from now we find life on Mars and it turns out being bread mold from the sandwich the probe forklift driver was eating as he loaded it onto a rocket.

Is it actually reducing the cost of space travel?
Or is it currently being subsidized by investors? If it’s the latter, eventually those investors are going to need to be repaid and it will end up costing more.

Right now the answer to both your questions is yes.
It’s significantly reducing cost, and that’s the purpose of all of the reusable rocket and craft tech we’ve seen succeed and fail over the last several years. The question is whether the cost reduction combined with some very rich customers will result in a sustainable industry that makes money.

It'll make money. Insane money. Wealth on a level the human race has simply never had before.
First step is mining near-Earth asteroids. Start sticking flags in chunks of platinum (or lithium, which is probably going to be worth more going forwards!) the size of football stadiums - and there's a gazillion of those within reach - and then ask what space is worth...and that's just for starters. Beamed energy arrays that soak up solar energy and transmit it back are next. Eventually you'll see all the dirty dangerous industries start getting moved up the gravity well to space where you're not going to be able to contaminate the water table with an oops-type spill or give a town cancer and there's no such thing as the EPA. Long before that you're going to see all manner of folks building habs in orbit and the various stable LaGrange points - L1, L2, L3, and so on - between Earth and the moon where they can start their own perfect societies away from the influence of meddlesome governments and nosy neighbors. Somewhere in that you're going to see folks headed outwards for Mars and the belt.
Once it gets rolling, it's going to make the Gold Rush look like amateur hour. Big thing is re-usable heavy-lift capability. Once SpaceX and the like get that rolling, look out, because the rush is on. If it takes 20 more years, I'll be shocked.

but NASA liked their vehicle so they gave them some cargo flights to the ISS. ULA will supply the rockets. They will be on ULA's new rocket the Vulcan.
Dream chaser could be man rated easily since that is what it was designed for originally.

I'm a huge fan of SpaceX. Their innovation is why the rocket launching industry is moving forward so quickly.
It will be good to tell the Russians to get lost after SpaceX and Boeing successfully launch crews to the space station.
With SpaceX, we can be sure an American company will dominate the industry into the foreseeable future. They have other things up their sleeve this year besides the Crew Dragon that will blow everyone's mind.

SpaceX doesn't have a factory in China or anywhere outside the U.S. Due to national security issues, only American citizens can work for the company.

Nerds!
Anyway, do I believe that a private company can outperform the gov in anything.... yes.
But,”Elon Musk’s growing empire is fueled by $4.9 billion in government subsidies”. That’s hardly a private venture.
The difference is that when Musk has an actual profit, the investors share it....but, the taxpayers made it possible.

could not be sustained. The U.S. is now looking at doing it in a way that makes more sense for the future. NASA is now the customer instead of a provider.
The fact that we now have safer, reusable, technology with fuels that are not toxic, and a cooperative plan around the world, makes this much more exciting.
The first airplane flight was amazing. But when society started building airports and utilizing aircraft, that was just as important, though it may not have elicited the same excitement.
