- billizm, on 06/29/2008, -0/+16Throw more junk up there. It worked in Futurama.
- tabassman, on 06/29/2008, -0/+16WALL-E!
- Craga89, on 06/29/2008, -2/+17Polluting the sun? I seriously doubt anything would get a few thousand miles from the sun before being incinerated.
- melonade, on 06/29/2008, -1/+14Very interesting. Pretty crazy that we're already getting ready for "space tourism."
- jjb123, on 06/29/2008, -2/+12Asteroids have been colliding with the sun for billions of years, I doubt our dead satellites will mess it up.
- drewbe121212, on 06/29/2008, -0/+7Wall-E?
- inactive, on 06/29/2008, -0/+4All sorts of people have all sorts of subjects that they enjoy discussing. Maybe you should get friends that dislike American Idol and Britney Spears?
- Thrilltone, on 06/29/2008, -0/+4A small bolt that may have fallen off of the MIR outhouse travelling at 10,000 mph will slice right through an astronaut.
- JazzFlight, on 06/29/2008, -1/+5Here is the solution:
http://en.wikipedia.org/wiki/Planetes - skoles, on 06/29/2008, -0/+4If they found that even things as small as paint flecks pose a danger why didn't they stop painting the rockets & shuttles? I'm sure it's just for cosmetic purpose unless the paint has some heat reflecting properties
- PhillyMJS, on 06/29/2008, -1/+5He said something about a "schedule conflict," and was last seen headed for the bathroom with a copy of 'Zero-G Juggs' tucked under his arm.
- metalsiren, on 06/29/2008, -0/+4not too much around in terms of hard-SF manga/anime. i enjoyed it.
- diggduggjoe, on 06/29/2008, -0/+4That cloud of debris may come in handy when the aliens come to invade us.
Anyway, it is good that we are looking to clean it up. It is a big job, unless we can find a cheap form of fuel to allow automated scoops to actively collect the crap. - danunderscore, on 06/29/2008, -1/+5You could always shoot tennis balls at them like Conan
- pell, on 06/29/2008, -0/+3Additional WALL-E reference.
- JasonCox, on 06/29/2008, -0/+3WALL-E + Fire Extinguisher?
- Mnevis, on 06/29/2008, -1/+4Those tethers are all well and good, but they don't fix the massive amounts of trash already up there. Nor are they effective if the satellite gets blown into bits during its mission.
How about a Katamari Damacy ball satellite? We launch a giant magnetic ball up there and via small bursts of thrust we send it spinning around the planet on varying trajectories. As it circles the planet it smashes into ***** and draws in near debris which gets magnetically bound to the ball. When done, launch the thing into the sun.
OH OH! OR we could turn the resulting ball into a fancy little orbiting junk yard. Then we could keep it in reserve for any incoming comets or meteors and just move the junkyard into the path of the doomsday body. I mean, the mess would be ***** huge, but at least we might still be alive, right? - bluechips23, on 06/29/2008, -0/+2Why not shoot lasers at those trash, thereby burning them in space?
OR
build a giant trash bag with special glue and stuff that can catch any floating tiny space trash
OR
Just let Wall-E do its magic? - jameshales, on 06/29/2008, -0/+2The point is that the debris takes too long to enter the Earth's atmosphere. It's orbiting, like whatever objects the debris came from.
- KingGorilla, on 06/29/2008, -1/+2Us pollute the universe? Do we have that kind of man power/resources?
- dwyn, on 06/29/2008, -0/+1Send tourists up on a trip to blast at trash with lasers... the Nintendo generation saves the world!
- terencec, on 06/29/2008, -0/+1put it in a bag, then the bag on the curb
- philforhumanity, on 06/29/2008, -0/+1Here are a few more suggestions: http://www.philforhumanity.com/Space_Debris.html
- swordedge, on 06/29/2008, -1/+2you won't pollute the sun. There is enough pressure from solar wind that anything we toss out into interplanetary space will orbit and probably leave to solar system in a few thousand years. Or to put it another way, it is fairly hard to make something hit the sun.
There is a nut scientist out there that wants to put Nuclear waste into space 4 pounds at a time sending it out of the solar system. By the time it reaches the nearest star, it will be inert - letherial, on 06/29/2008, -0/+1that plus we could also send them up there and sale the junk...look honey, i picked this up from space....capitalism at its finest
- odiego, on 06/29/2008, -0/+1Thanks.
- didgital, on 06/30/2008, -0/+1absorbing actually. mylar and mirros do most of the reflecting
- didgital, on 06/30/2008, -0/+1Not all objects in space fall, it depends on how close they are to our planet. If they're close enough, they eventually re-enter and burn up (most of it, most of the time - titanium propellant tanks are the best at making it through). Some will float there forever at ~17,000 mph (moving in any which direction to the earth -except elevation) unless it hits another object (exponentially becoming more debris) or it's eventually removed.
- didgital, on 06/30/2008, -0/+1Please keep reading the science section. Eventually you will realize our atmosphere is not the universe.
- starmanjones, on 06/29/2008, -1/+2i think it was a joke.
- odiego, on 06/29/2008, -2/+2Why dont the debris burn when entering the Earth's atmosphere?
- wilhoitm, on 06/29/2008, -1/+1Send all of it to the Sun and cause a Super Nova! Adiós, Muchachos!
- zebraz, on 06/29/2008, -3/+3Define trash.
If it cost some crazy price to get the trash up there.
It should be worth something.
You don't get that junk up there for free. - Siesna, on 06/29/2008, -1/+1I think that's the point of the "Laser Brooms."
Laser Brooms: Baseball-size pieces of debris are too small for tethers but large enough to pierce spacecraft. Hitting them with lasers would disrupt their orbit, causing them to fall and burn up.
I think they're concerned with larger objects that won't burn up. - diggwebq, on 03/15/2009, -0/+0Define trash.

http://www.zestrx.com/product/cialis.html - madwaxer, on 06/29/2008, -1/+1i've got a good one, launch a really large magnet with tentacles of iron cable attached (will only work for metals at first. then send a few into different orbits around earth to pick up the junk out there using controlled thrusting. when its done send it off to the sun in a slung trajectory path. the odd missing spy sats wouldn't be too badly missed tho
- gotikon, on 03/09/2009, -0/+0Not only are we polluting the planet...but the whole universe?! Typical. ;)
“A more feasible plan is to attach miles-long “electrodynamic tethers,” wound on a spool, to all new satellites. Once a satellite ends its mission, it would deploy the cable and Earth’s magnetic field would induce an electric current in it. This interaction imparts a force on the craft that pushes it through the atmosphere until most of it burns up harmlessly, says Rob Hoyt, the president and chief scientist of Tethers Unlimited, a company working to develop the technology.”

- kutsal, on 06/30/2008, -1/+1Gather them up into a huge ball of space-trash, attach a rocket to it, and send it on a trajectory towards the Sun while avoiding the rest of the planets along the way.
Problem solved. - babygirlcrib, on 11/15/2008, -0/+0http://generalelectricdishwasher.blogspot.com/

http://daybedcomfortersets.blogspot.com/ - Siesna, on 06/29/2008, -1/+0I've always wondered why we just left all that crap floating around up there.
- beesaretasty, on 06/29/2008, -2/+1Send it to Uranus!
It doesn't even make sense but I like to make myself laugh. I have the mind of a 12 year old. - bara3190, on 06/29/2008, -1/+0I really liked your article, particularly this paragraph it makes a lot sense. Possibly Johnson would consider using spacecraft (Shuttle or the new orbiter) when headed to the space station or on return to push the debris closer to earths orbit. I know NASA uses the shuttle to help keep the station in orbit.

"Enemy" satellites could suddenly be considered "debris"; hit them with the laser...
- Paramnesia, on 06/29/2008, -2/+1Yah there is an idea - Forget investing in biodegradable plastics (already invented), reusing our raw materials etc.
Giant slingshot for the win! -
