Pacific likely for satellite fall
www.bbc.co.uk
US officials still talk about late Friday (GMT) for the fall to Earth of Nasa's defunct, six-tonne UARS satellite.
- UARS orbited the Earth between 57 degrees North and South
- Nasa calculated some 26 components might survive the fall to Earth
- The largest was a moveable instrument platform weighing almost 160kg
- In total, about half a tonne could have made it all the way to the surface
- The risk of any one of 7bn people being hit was 1 in 3,200, Nasa says

Hello weekend,
There's an article written by Jonathan Amos, there's his smile, there's my eyes, and I read his writings. Currently I'm listening to music, faint, and as my love story that has been deprecated, hurtling back and forth above the ceiling of my life has been quite old, and some time it will be plunged into my heart with a terrible condition: marriage, but nevertheless it has not been done, even more backward than the day I had anticipated. As on Friday morning, NASA researchers analyzed, the sun is no longer a major factor in the rate of decline in the satellite falls to Earth, then ... hmm I was measuring, what is the most appropriate analogy to the sun in my life story? .... Love? Ah, I've told myself, it was too out there, more obsolete than the sun.... shananana. If so, haa... yesyesyes! I got it! Sex! Yes! Sex is the sun in my life, and it's no longer a major factor in the affairs of this marriage. Ehheeh ...
Just like the British royal air force(RAF) that been at the forefront in efforts of countries to track the UARS satellite (which is expected to fall), my closer friend has called me many times asking this problem. The air force base of RAF Fylingdales in North York Moors has used giant radar to track UARS. This base has a network of radars with the strongest ability to track in the world radar, it was able to track all objects in the orbit, even starting from small objects with a size of 10 cm, then as a closest friend, he was also able to track my heart's content until the unspoken things. But, well ... so, such that its base, being built in an atmosphere of cold war to keep track of all the missile attacks, then the role is still played to this day. I mean, the role of a close friend of mine ...
"The operating room space at the air base Fylingdales works 24 hours every day by the military and civilian personnel. Now it will work to track UARS when it enters the Earth's atmosphere," said an RAF spokesman to media on Friday (09/23/2011). "Solid State Phased Array Radar (SSPAR) will be used by both of British and U.S. Air Force to track the UARS final orbit, "he said, as well as what was said by my closest friend, "I'll be with you every time you need me in anything". He didn't just say to me but also embraced me and kissed my lips. I did not return his kiss.
That information would be used by various agencies across the state to predict the return of UARS traces in Earth's atmosphere. Furthermore it was said that with the majority of the earth was water or the ocean, then the chances of its falling to the ground was small. Yesterday, an aerospace company in California predict UARS would fall around Pacific Ocean. The satellite wreck was touted as the largest space junk that fell to earth in 32 years. UARS satellite was launched in September 1991 by space shuttle "Discovery" to examine the ozone layer, to measure the wind and air temperature.
For the long history of romance in my past, my close friend said, "Ouch, damn your future husband!" hahaha
NASA said the UARS down again and would arrive to Earth at 13:23 until 15:09 local time, but time and location were still uncertain. The satellite passed over eastern Canada and Africa and mostly through the Pacific, Atlantic and India during that period. NASA has repeatedly said the potential collapse of UARS debris in residential areas was very small indeed. Satellite component was expected to melt due to friction that occured in the atmosphere. But there were approximately 26 sections that might not be destroyed in the atmosphere and re-entry into Earth. NASA said the lightest part of the UARS wreck components was weighing one kilogram and the heaviest weight reached 159 kg. They were expected to fall and spread with a range of 800 km.
The extent of falling location (as estimated by NASA) made the determination of it became a very difficult thing to do. But because the Earth's surface area is filled with water up to 70 percent, then most likely the object will land there. "Throughout the history of the space program up to 50 years, there has not found anyone who had been wounded by a piece of space junk that goes back to Earth," said Mark Matney, a scientist who studied the debris at NASA's space object. Matney also added that it was necessary to note, NASA has pieces of junk back into the atmosphere every day.
Do you know what is NASA on the ceiling of my mind? It's my mother!...
... So, exactly, what was I waiting for the fall? See, his smile is like a Betelgeuse in the galaxy of my mind, every weekend. Jonathan Amos. Then I drop my body into bed with a nameless feeling.25 September 2011 Last updated at 00:31 GMT

Dear Amos,CZ-LA 92811
A friend while eating toast with me asked jokingly, "Gee, why doesn't it fall in the lap of George Bush?"
Then the joke was overlaid by another friend, "Or fall in to the laps of dashing countries that become the American allies, such as France or England,.... for example?"
Maybe she was just looking for a close neighbor of the UK and taking France as an example, but she made me slightly disagree.
"French?" I was stunned for a moment.Then simultaneously crossed two faces full of love in my head. A man's face and an object that was chewing the toast.
["A man's face is his autobiography. A woman's face is her work of fiction" - OSCAR WILDE's quote]It was Valentino Vie's face and the object was my mouth on my face. My mouth! My face! My fiction! Well, but at that time I felt no close relationship between my mouth and my mind or between my work and my fiction.
That joke was also enlivened by closing words of a friend who always spoke more wisely, "Never mind. Whatever happens in space, it's not a problem on earth. The earth's natural satellite has been named as the moon, and the UARS is just a man-made satellite, that's why the UARS always related to technical factors. Look, the moon never fall into our laps, though for once. There are many catastrophic events on earth that is more evident, for example the typhoon in Philippines. (Hello, Philippines) What are the benefits we focus on expensive projects while the famine in Somalia still need to be tackled..., for example. Why do the scientists more proud to spectacular project but less humane? "
"Well, science is important!" I replied.
"Yes, but the space science for me is more easily achieved with a dream!"
"What do you mean?"
"Well, I can't go to buy a ticket freely to prove all the info from NASA! Perhaps to death I'll never be able to go to the moon to cover the news directly ... hahaha.. all the news about space is too theoretical for me!
"I have a ticket for you!"
"Yeah?"
"Yeah. One way ticket to the blue!" said my other friend.
"What do you mean?To the blue sky?"
"No. To the blue feeling!"
"Ahahahaa....
