Clean Up Space Junk or Risk Real-Life 'Gravity' Disaster, Lawmakers Say
space.com ^ | 5/9/2014 | Denise Chow

Posted on 05/10/2014 6:31:17 AM PDT by rktman

While the plot of the hit Hollywood film "Gravity" is fictional, the United States must bolster efforts to address the alarming amount of space junk surrounding Earth, or risk potentially catastrophic collisions in orbit, lawmakers said today (May 9). Such real-life accidents could resemble the horrifying destruction depicted in the movie, they said.

Simple. We just launch a couple of space shuttles and tow big nets behind them. Oh, wait. We don't launch space shuttles any more. Well we'll just use one of our other manned vehicles then. Oh, wait. We don't have any of those either. How about we use some of the inputs from the muslim world that has helped our progre........... Hmmm. Can't recall that either. Calling chaz bolden, calling chaz bolden. How about a little more outreach there charlie.

99.9% of all the stuff in orbit would burn up on re-entry.
This is just alarmism and chicken little talk.

Fifty foot holes with trampolines. Isn’t that the new plan?

lawmakers said today.

Because as we all know, lawmakers are the real subject matter experts, as they've shown time and time again.

It must be the fear of that .1% smacking their house that they are really scared about. See maps at link:

A cost effective idea I like is nicknamed “a big ball of goo”. A satellite is launched, and once in orbit its protective shell is discarded. The satellite then projects telescoping tubes. The end of each tube is attached to a large “tent”, so as the tubes extend, the tent expands to become an irregular “big ball”.

An inert gas is pumped into the vacuum within the tent, which warms in sunlight, then a high expansion polymer foam is sprayed into the tent. When warmed by the Sun it is a sticky goo, and shaded by the Earth it is hard but flexible.

After that, the idea is to either collide the ball of goo with space junk, or for the space junk to collide with it. That it punches holes in the tent does not matter. And though its inertia will destabilize the orbit of the satellite, it can be adjusted by pumping inert gas through some of the tubes.

After colliding with perhaps tons of debris, its orbit is decayed so that it all burns up in the atmosphere.

Right, and how do they deal with all of the air resistance? The nets will pull the Shuttles straight down.

So good that all the REAL problems are long solved.
Now we have so much time and resources to deal with this problem and don’t foget about Globull Warming....

Oh great, polute the earth with burning debris. We should just take video of the junk, then turn off the monitor. Presto, junk-be-gone. /s
Hey, its just as rational as earth being deflated by space junk.

LOL! Deploy the nets AFTER they reach orbit. Oh, wait. We don’t do that anymore anyway. I’m thinking the Smithsonian ain’t giving hers up anyway. Or LA or the one at the visitors center at KSC either. Not to mention, the infrastructure has been rendered useless already. Now, where’s my hard hat?

Attain orbit, then deploy nets.

I wasn’t even thinking that...but yea, those nets would have to deal with some pretty violent heat from the engines at launch. LOL.

"Space," it says, "is big. Really big. You just won't believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space, listen..."

Hitchhikers Guide to the Galaxy - Chapter 8

Even that miniscule portion of space inside the orbits of Geostationary satellites down to Low Earth Orbit is a volume on the order of 100 Trillion cubic miles.

Give the job to Congress, the Treasury or Obama'a Budget gurus, they think nothing of dealing with Trillions of this or that.

I can see it now. The BSM* will get funded to address the issue.

This is not news. That risk has been there for a long time already.

The project will be halted until an Environmental Impact Study is done concerning the Endangered Flop-Eared Space Tortoise.

They just figured that out huh? We’ve only known there’s a dangerous quantity of man dropped crap out there for 20 years, maybe more. But somebody makes a movie and suddenly the government listens.

“After colliding with perhaps tons of debris, its orbit is decayed so that it all burns up in the atmosphere.”

Nice idea except a sticky ball with tons of debris will not burn up in the atmosphere.

As the outer shell heats up, the heat gets transfered to the core. When enough pressure builds in the core, a massive gas detonation will occur a mile or so above the ground. It will be similar to the Siberian explosion in 1907.

The problem isn’t re-entry, the problem is trying to launch stuff through it. Orbital speeds are really high, a nut can do a lot of damage to a ship when traveling at these speeds.

Why don’t they just add a small retro jet that can push the stuff in to atmosphere when launched. A money making project for a company to send up drones to nudge the stuff down.

Oh gosh.

First, I couldn’t sleep at night because of the impending disaster caused by Global Warming.

Next, I couldn’t sleep at night because of the impending disaster caused by Global Climate Change.

Next, I couldn’t sleep at night because of the racism being spewed by Donald Sterling.

Now, I can’t sleep at night because of the impending disaster that will be caused by space junk.

I am concerned that soon I will be unable to sleep at night because of the lack of potential man-made disasters.

What is a Freeper to do?

Space shuttle windshield section. Damage from a paint chip. A bolt probably would have taken it out.

I don’t think we’re putting retro jets on what is literally millions of little nuts, bolts, paint chips, and other chunks of crap. The danger isn’t the big things that can be easily seen by eyes and radar, it’s the little Ace Hardware store effluvia that our space missions leave behind. Think of it like highway rocks, only instead of your car doing 75 it’s doing multiples of the speed of sound.

At the end of the video the key issue this congressional committee will have to deal with is - who will be designated to attend a conference in Paris in June?

Thanks for your thoughts & humor...

The first two are proven-bogus impending "disasters"...

The Sterling-NBA flap has used up it's 15 minutes on this news cycle.... Then again (& JMO):
There will be 15 more minutes for this one....
.....When he prefers charges for illegal wiretapping a private conversation...
-- AND successfully sues the NBA et als for defamation of character & interfering with his personal/privately owned business interests.
(He has a constitutional right to be a bigoted idiot and still say what he pleases in private-- & the reputation of his business interests remain protected by civil law)

*********

The Kessler Syndrome is real research with real scientific probabilities
(If I recall correctly... the Cascade Theory was his doctoral thesis)....
--YET--
The "disaster" will take place in orbit -- rendering a lot of spaced-base tech useless...

I guess that's better than lying awake at night wondering if some satellite is going to land in your back yard...
.... OOoorrr....
Put a knot on your punkin'....
Just say'n....

ENJOY YOUR WEEKEND

Don't forget to think about the space flotsam created when the Chicoms destroyed one of their satellites in orbit.

Yep. "The Kessler syndrome". Thanks. I was trying to remember what it was called.

I loved Gravity, BTW. I know it had a few science errors but that's OK. It's entertainment. My only regret after the final credits rolled was not seeing it in the theater.

I’ve read that the ISS is all banged up from the outside from tiny pieces of leftover satellites colliding with it.

Just put booster rockets on all satellites so when their useful life is over, you can launch them into the Sun and they’ll just burn up. Yep, that will be effective....

I think it highly unlikely that a polymer ball would do that, having a density about twice as great as Styrofoam.

Best bet is to deploy a spaceship with a tractor beam. Scientists have shown such a force is feasible in experiments. Just get Obama on board to fund a project, should only cost 100 trillion or so. Obama loves spending money, should be a cinch to approve this.

Clean Up Space Junk or Risk Real-Life 'Gravity' Disaster, Lawmakers Say

Well, DUH!

Unfortunately...

All normal citizens, students, the MSM, politicians and "specialized" "scientists, all share the gift of self-imposed ignorance.

The only concept of the constellation of satellites they know are the graphics regularly on TV and even "Science" channels, which grossly distort the actual scales involved, and resulting "empty" space.

Few are curious enough, intellectually, to actually learn and see the reality beyond the cartoons.

And they all fall prey to the propaganda scaremongers.
