Late Friday 23rd September, 201 night, officials at the NASA, announced they expect the re-entry between 11:45 p.m., eastern time and 12:45 a.m.
NASA has narrowed the window for re-entry of a six ton satellite, with the news from Kennedy Space Centre.
On twitter NASA spent the day answering questions from other users.
• Myth of 'flaming space debris" - Pieces of #UARS landing on Earth will not be very hot. Heating stops 20 miles up, cools after that.
• Pieces of #UARS will have slowed down a lot by the time they reach Earth: could be as low as 30 mph.
• Nothing radioactive on #UARS. Main reason NOT to touch anything that you think could be debris: sharp metal cuts.
• Earth, in orbit, plows through several hundred tons of meteors per day. So we'll all survive Friday's 6-ton falling satellite
• #UARS hasn't landed yet, If the debris hits the ocean it wont cause a big wave. The pieces aren't that big.
NASA and the world are still waiting to see where pieces of a soon to be burned up satellite might land.
NASA said the satellite will pass over Canada and Africa, as well as the Pacific, Atlantic and Indian oceans.
Solar activity is no longer the major reason in the satellite's descent. Rather, its orientation apparently has changed, and that's slowing its fatal plunge.
Water covers about 70 percent of the planet's surface, so it is very likely that the debris from this satelltie will fall into a body of water.
On Friday, NASA put North America back in the possible target zone, with a low chance that any surviving debris will land in the United States.
The odds of a person being struck haven't changed: one in 3,200.
It's the largest satellite to enter the Earth's atmosphere in more than 30 years, and a much smaller concern than the 75-ton Skylab that fell to Earth in 1979. Debris from that device hit Western Australia.
Entire India was on tenter-hooks particularly, Telangana and Hyderabad at the Skylab re-entry in the year 1979. many selling away their properties, cattle, farm lands and belongings, as some others making merry and last feast before the doom. A few others went to cities and spent time nearer to hospitals in hope of quicker medicare in an eventuality of the SKYLAB hitting them.
Many people selling away their cattle, etc., leaving homes and going to other cities and states fearing the Skylab. Many offered prayers and made peace offerings at temples, mosques and churches.
I was a student of Osmania University, and went riding my Royal Enfield BULLET bike, in and around, Hyderabad India, finding a curfew like situation and the city roads filled with people and their cattle huddled on the pavements and roads.
It passed off, with the SKYLAB falling in to the INDIAN OCEAN some where near Perth, Australia, every one heaved sighs of relief, but for some when they returned to their homes found their houses burgled etc.,
To date there are, Cafetaria, restaurants,shops, bars etc., named SKYLAB in Hyderabad and Secunderabad, and many other towns and cities of Telangana.
Now mobiles, net, TVs and so on and the business of the TELANGANA STATE struggle not much of the frenzy is not seen at all anywhere in TELANGANA
