          Thousands of tons of crap enters the atmosphere every day. You could probably make a suit out of ,say, plutonium and still have negligible effect considering:

          One spacesuit+electronics - 50kg, tops.
          Atmosphere - 5,000,000,000,000,000,000kg (by most estimates).

          Even guesstimating that it might incinerate and cover an area 1/8th the size of the globe during re-entry, that's still pretty much SFA. Even with plutonium being the nasty thing that it is.

          Of course, the associated problems of dealing with 50kg of plutonium in one place at the same time is left as an exercise for the reader.

            Apart from that, yeah, a shoddy old spacesuit should do no difference - whereas it would do a difference if more people started taking the bus (or even better, the bike) instead the car to work.

        That would seem to indicate that if the ISS didnt make any prograde burns, it too would be entering the atmosphere in several weeks.

        I say wierd because I had presumed that ISS, like Mir would take a few months to reach an unrecoverable orbit which would lead to a re-entry.

        SO, they throw it downwards when they launch the suit? Well, Im no physicist - and this is only what I remember from my school days; if you were to throw something downwards with the maximum force available to a human from the ISS, then the object would return to you hours or days later because its angular velocity in relation to the orbit wouldnt have changed.

        In order to actually alter the continous orbit of the suit as you launch it, you would have to either throw the suit out ahead of the ISS (To make it go higher) or throw it backwards along the ISS orbit to make it go lower.

        However, I would rather suspect that an overhand throw of a spacesuit wouldnt make any siginificant difference in the time taken for re-entry to occur.

        Come to think of it. - Every force has an equal and opposite. which indicates that the ISS crew are going to have to fashion some sort of rocket to get the suit going. - A small compresses air cylinder would come to mind but would be hard to aim. You could of course blow it from the airlock but youd have to correct the ISS orbit using Progress afterwards.
        • That would seem to indicate that if the ISS didnt make any prograde burns, it too would be entering the atmosphere in several weeks.

          According to Wikipedia, "The station, on average, loses 100 meters of altitude per day." (and is periodically reorbitted).

          Of course the station has much higher mass compared to the suit. Since (for a given exposed surface area) the atmospheric drag is the same but the mass is less for the suit, the drag will decellerate the suit at a higher rate to the station. Obviously t

      It is cool for hams to get satellites into earth orbit. Amateur Radio is perhaps one of the first examples Open Source or community development. From the very start; amateurs developed radio circuits, techniques, and standards that were openly published for anybody to use. Some of the right people understand the usefulness of Amateur Radio and the need for such projects.

      In most cases the people building ham satellites are hams, with some corporate support. The really cool part is that the various national space agencies allow / takes part in the deployment of the ham satellites.

Sadly, none of these satellites is currently considered operational.
