#22: "Why is this so hard if NASA can predict the weather 100 years out? (sarc)"

That is actually a very good point. The same physics that governs the motion of this satellite governs weather patterns.

The complexity of climate prediction is beyond all the computing power on earth combined. Even if we knew the equations, we could never know the initial conditions which rule them. Only God has that kind of omniscience.

Skylab Fallout cocktail recipe

1/2 oz Absolut® vodka
1/2 oz Bacardi® 151 rum
1/2 oz gold tequila
1/2 oz gin
1/2 oz Everclear® alcohol
1/2 oz Blue Curacao liqueur
1/2 oz pineapple juice

Put plenty of ice in glass pour rum and everclear first refill with ice - put your tequila, gin, vodka and your blue curacao in. Put your pineapple juice in and shake, serve with a lemon slice and cherry.

*****

Ow, my head hurts just remembering this. I suppose that if one were to delete the vodka and add an equal measure of Baijiu, all you'd need is to rename the drink appropriately.

LOVED that show! Janine Turner was gorgeous, even if her hair was too short.

Heavens Above doesn’t track every piece of space junk, of which there is a lot. A tumbling booster state is possible, but they’re typically dropped before reaching orbit. There are also things like discarded panels, interstages, etc. One astronaut was working outside the ISS and lost a whole tool kit.

Rest in peace Commander Husband/crew STS-107.

Somewhere in my old PC hard-drive I've got a(low quality)video I took of the ISS overhead with the shuttle trailing behind.

Dittos to that! GREAT show! (”In your dreams Fleishman”!). Back many moon ago I spent a lot of time ‘relaxing’ (Heh!) in Roslyn’s, (TV’s Cicely), Brick Tavern after a day’s off road motorcycle scrambling in the nearby coal hills and mountain trails. Good times from a long ago time. Not sure of the time frame, but I think the tree huggers shut all riding down about 40 years ago there.)

Yeah, it looked like a largr cylinder going end over end, causing the light fluctuation. But it was with some cheesy high power binocs so I had to guess it was not very high if I could see the shape. Might have fallen sometime after, from someone’s launch.

Meteorites are worth good money. If a meteorite hits a building it is worth a lot more. Don’t know the value of space junk.

Walmart might be interested in selling Chinese space junk. Rollback priced appropriately named.

I can barely see the rings of Saturn with my 16x binos (the shaking doesn’t help). The angular diameter of the ISS is only slightly larger than that, when about 200 miles directly overhead. Even if what you saw was much lower, say 100 miles, it would have to have been very large to see its shape with binoculars. Still possible, however.

This article doesn’t take account of a very significant effect on a decaying orbit, due to the oblateness of the earth.

In Tiangong 1’s case, its orbit is tilted at about 43 degrees to the equator, and due to the equatorial bulge it comes closer to the atmosphere by about 10 km, twice each orbit as it crosses the equator.

I have seen very little mention of this, but the basic fact can be verified.

I have been using a tracking site, in the name of n2yo ( a radio call sign, ) which evidently DOES take this into account, in addition to the eccentricity of the orbit, which has only one high and one low point per orbit, of course.

It seems to me that this would be important in predicting the time of the final plunge, since I would think it would occur on one of these “dips” when the orbital nadir aligns with the equator, because a dip in surface altitude of an extra 10 km, say, could “snag” it.

Well, that’s all beyond my, ah, “resources”, so I’m contenting myself with obsessively watching the track.

I think it’s great that a mentally retarded person like yourself has learned to type and to use the Internet.

Wish you all the best on your path toward independent living!
