An interesting note right at the end, so in case anyone missed it: this same launch is believed to be the source of 5 titanium "spaceballs" that fell onto New Zealand in 1972.<p>While the odds are low of any space debris hitting land, it was the photo in this article that surprised me - I was thinking billiard ball size debris, not this - <a href="http://www.stuff.co.nz/the-press/4542804/Government-report-on-space-balls-released" rel="nofollow">http://www.stuff.co.nz/the-press/4542804/Government-report-o...</a>
> The balls, which had Russian markings, were used to pressurise fuel tanks or as stabilisation jets, the report states.<p>Spent a bit of time in the metal trade, sometimes various metals that can best be described as oddities from Sheffield would be heading south, one such time some metal pieces were on this lorry no bigger than a chunk of cheese or hash brown thats broken off, clearly its been part of a larger plate of metal, but its magnetic strength was so strong it needed a screw driver to leverage it off anything it was stuck to. Never seen anything as strong magnetically since, but it had became a sort of competition with people/visitors asked to try to pull it off what other metal it was stuck to.<p>> 20 kilogram, titanium sphere,
> It is not something you would sell to a scrap dealer,'' he said.<p>The titanium being sold as scrap would come down in bars which had been angle-grinded all over to produce long metal splinters so that it could only be handled with a fork lift, the splinters would go through gloves if you tried to handle it. That shows to what lengths some scrap metals were "processed" in order to avoid being stolen.
Can anyone explain how it's possible for the apogee to reduce so much, while the perigee barely changes?<p>Wouldn't the air resistance that lowers the apogee also affect the perigee?<p>Or is it specifically because the object is being slowed at perigee, that the apogee lowers, while the perigee doesn't change much because the apogee is in vacuum?
If a chunk of Soviet space junk falls on someone's house, does the Russian Federation just shrug and say, "That was the USSR, bruh, sorry." They must have assumed responsibility for the Soviet space program, right? It's sort of like firing a bullet into the air... Doesn't matter how long it takes to come down, it's still your fault if it kills someone.
Napkin math: earth's surface area is ~510 million square kilometers. The lander is described as fitting in a 1-meter protective shell. So we have a roughly 1 in 510 billion chance of standing in the lucky spot.<p>(This of course would only be accurate if all square meters of the earth's surface were equally likely to be hit. Not the case since the lander appears to be orbiting the equator.)
tl;dr on why its relevant:<p>„The reentry of the Kosmos 482 Descent Craft will not be your standard reentry. The Descent Craft was designed to survive entry through the dense atmosphere of Venus. It will therefore likely survive reentry into the Earth’s atmosphere intact and make a crash landing (it is extremely unlikely that the parachute system will still work after more than 50 years in space). This will therefore be a high-interest reentry.“
A water splashdown is the highest probability. But I think even with the 52 degree envelope, Russia is still probably the largest landmass in that envelope? So I take ironic pleasure knowing it’s more likely to smack back into Russia than any other country.<p>(I’m making an educated assumption about the geography, but could be wrong)
