SpaceX launches 60 mini satellites into orbit

Is that a joke or is it real? WOW!

Space junk has wounded several satellites. Someday someone is going to have to figure an economical way to gather that stuff. A stupid stunt by the Chinese a number of years back was to test a satellite destroyer. It worked, the mock or dead satellite exploded scattering junk everywhere. Whoops.

Maybe eventually they will invent some kind of command for a satellite that is nearing it's expire date to self-destruct or come down?

Like the Mission to Mars, it is a fragile dream. It seems highly risky and speculative. The chances that the Company will crash (literally), before their stock sky-rockets seems very high. We can call it the Communication Revolution.....and hope for the best.

If you read up on Elon Musk, he's a genius. He taught himself code at age 12 by getting a book, then invented a game that he sold for $500. He started his career by getting a $28,000 loan from his father, which he repayed in full. He started one company, sold it, started another which became Paypal which he sold to Ebay, then got TSLA and founded SpaceX. His dream is to found a colony on Mars. I don't know why, but we all should have a dream, it lifts our spirits.

Mars used to have an atmosphere, like Earth, but somehow lost most of it. I've heard of a theory that something can be done to replenish or restart it (it went over my head)***. If anyone can do it, Elon can, or he probably will inspire others to do it after he's gone. Elon has as many admirers as he has haters. One of his biggest critics and hater is Einhorn, and Elon has invited him to tour his Tesla factory. That is pretty magnanimous! I wouldn't be surprised if Einhorn comes away a reluctant admirer.

*** If that is not possible, they can always construct something like we have here in Tucson, where people can live inside it and grow their own food.

I understand that many people want it to work, but the unknowns, including costs are huge.

Well, Musk is able to do missions for 1/3 the cost of other big players like NASA and Boeing. He's been re-using rockets that used to be scrapped, saving millions. Computer hard drives used to fill up whole rooms, yet now they're very tiny (and much cheaper). One positive thing you can say about the human race, they're innovators. They went from inventing a crude wheel to inventing space machines that have traveled to the edge of our solar system.

SpaceX it looking at putting 42,000 up there in order to eventually cover the Earth's outer region with a giant net (maybe) of Starlink satellites. This has astronomers troubled. Does this trouble you? I don't know how I feel. Everybody should love satellites right?

How bout a net to catch the space junk? Then no one will get killed and they can recycle, right?

How about just blowing everything into outer space? Then it will be someone else's problem, if they are out there.

I thought about that, too, but it would be self-harming when we Earthlings start space explorations. It's hard enough avoiding meteorites, never mind thousands of man-made junk. Musk's "Starman'' riding in his Mustang is one too many already. šŸ˜’

I was kidding. Please keep the junk orbiting your planet to yourself. How about landfills on the moon?

That would be a great idea, we could clean up Earth and take it all to the moon. BUT, big companies plan to mine the moon in the future for its minerals, I don't think THEY would like that.
