I heard that because earth is 70% water, it will probably land in water.
But according to [1], its movement is almost evenly split between land and water in the uncertainty interval.

- tlamponi 5y agoBut still, the last time China did this metal parts sprayed down on a ~150 km wide land stripe in the Ivory Coast... If it would just hit those ignorant people not caring about such impacts they would maybe re-think...
- iamgopal 5y agoYes, ignorant people should think and rethink twice before becoming ignorant.
- wungsten 5y agoThey meant China should re-think, not the victims.
- lupire 5y agoWere there damages reported? Low population density areas give low odds of collisions, plus free metal to be scavenged/recycled Article here mentions metal found but not damages. https://www.newsweek.com/chinese-rocket-rained-metal-ivory-coast-earth-orbit-1588865?amp=1 https://www.newsweek.com/chinese-rocket-rained-metal-ivory-c...
- tremon 5y agoI'm not sure how to read that chart. Is it showing the object is expected to circle the earth 4 more times, then crash somewhere to the west of Australia?
- Ajedi32 5y agoThe legend says: > Yellow Line – ground track uncertainty after predicted reentry time (ticks at 5-minute intervals) > Blue Line – ground track uncertainty prior to predicted reentry time (ticks at 5-minute intervals) So the rocket could re-enter anywhere along the yellow or blue lines.
- tremon 5y agoThanks, I had completely missed that legend. It was folded by default here (?)
- Denvercoder9 5y agoActually, it can also re-enter outside of the yellow or blue lines. They given an error margin of 24 hours on the predicted reentry time, and the drawn tracks are only 6 hours long.
- Ajedi32 5y agoLooks like it just updated; margin of error was reduced to 22 hours and the drawn tracks now show the full range. I imagine that as the rocket gets closer to reentering the page will continue to be updated with more precise estimates.
- MadVikingGod 5y agoThat is the orbital prediction at the estimated time of reentry. They take where it is right now projected about 3 days out, and show us 6hrs before and after. LEO takes around 2 hrs or less to circle the earth. This will change. If there is more drag then expected, or any one hundreds of different things happen, the reentry time will change, and then the predicted area will change.
