Along behind the shuttle, trailing on long (long) lines are big wads of duct tape, sweeping the heavens for teeny tiny little pieces of space debris, all of which will stick. A cheap way to troll the heavens and thereby increase our knowledge, what better material to use? Back in Houston..." A ring-tab?"
Space dust capture
http://news.nationa...spacedust.html#main
At the end, they propose gathering space dust using aerogel - really very similar to [stringy's] proposition! [bungston, Oct 04 2004, last modified Oct 06 2004]

Start unwinding duct tape in space and you're just going to turn the asteroid belt into one giant sticky mess. |

Thats precisely what I was thinking, [Mr Burns] ... I have the original NES release of Metroid |
|
| |
Its for sure one of my top favs ... I'll trade you Super Metroid for a Mark McGuire Rookie card, and my soda at lunch tomorrow! |
|
| |
Man, you folks are as old as I am, I remember meteroid! And I have seen the andromeda strain... scared me, too. But you don't think that any of that stuff cound come unstuck from a whole roll of silver wonder, do you? |
|

You need to rethink this while considering the relative velocities of the objects involved. Then you will see why it would not work as planned. |
|
| |
Ahhh, but you see, that is all realtive! I *might* pickup "something!" And that would happen all for the price of a roll of duct tape. It is an experiment, so there is no way to predict the results successfully ahead of time, since your prediction is based upon assumption, no? So, if you haul in the tape and study whatever is attatched to it, and find nothing... no big loss, either. |

No, you won't pick up anything. |
|

You are right, it's all relative. Since you didn't bother to check into the velocities involved, here's your lesson. Your shuttle is traveling at about 8 kilometers per second. Meteors/meteoroids are traveling about 42 kilometers per second, over five times faster. Even if traveling in the same direction, your meteoroid will strike the duct tape at a relative velocity of about 70,000 mph, which will penetrate it faster than any bullet fired on earth. |

No one has mentioned the fact that it’s bloody cold up there. The sealant used for duct tape would become a very thin film of un-sticky and quite inflexible ice. |

There is some merit in this idea. Currently, space dust is gathered by means of a large funnel on the nose of a very high-flying plane (I will look for a link). It seems an inefficient way to gather space dust. Conventional sticky duct tape will probably freeze - although maybe not, depending on solar radiation - it might get pretty hot. Instead of duct tape, you could do this with long, charged mylar strips. They could be very long, trailing behind the shuttle for miles. Not only would it look beautiful thru a telescope, it might pick up a lot of dust. Even if the dust were moving fast, and even if it punched thru the strips, dust is small and should be stoppable by electrostatics. |

I can appreciate the validity of your technical explanations, and even agree... but why don't the astronauts meet the same fate you describe during EVA? Is there some way then, to use the suits they wear to capture particles for analysis? |
|
| |
// why don't the astronauts meet the same fate you describe during EVA? // |
|
| |
Because they are wearing substantially more than duct tape for protection. |
|
| |
The solution is to trap particles inside of material that will slow and capture them, such as aerogel. As you can see by bung's link, NASA is way ahead of you on this. |
|

NASA is way ahed of me on a couple of things, but it is fun to dweam...Now what am I gonna do wid alla dis tape?? |
