The 6 ton dead satellite that has been plunging towards earth for the past several days has finally landed. NASA scientists cannot yet determine exactly where the satellite crashed, but they did say it was somewhere in the Pacific Ocean. Many are wondering where the huge pieces of supersonic debris will turn up?

Most of the satellite was expected to burn during its descent, but NASA predicted 26 large pieces of supersonic debris will survive all the way and hit the earth’s surface. NASA warned the debris could weigh up to 330 pounds a piece, and will stretch along a 500-mile path.

Scientists say the risk of damage is very small. A significant amount of debris does not survive the severe heating which occurs during re-entry. Components which do survive are most likely to fall into the oceans or other bodies of water or onto sparsely populated regions like the Canadian Tundra, the Australian Outback, or Siberia in the Russian Federation.

s of Friday Sept. 16, 2011, NASA’s Upper Atmosphere Research Satellite, or UARS, is expected to re-enter Earth’s atmosphere September 23, plus or minus a day. The re-entry of UARS is coming a day earlier than previously predicted because of a sharp increase in solar activity this week. Solar effects from the sun can create an extra drag on satellites in space because they can heat the Earth’s atmosphere, causing it to expand, agency officials have said.

The exact date and geographic location of re-entry is hard to predict because it depends on solar activity and the satellite’s orientation as its orbit decays. As re-entry draws closer, predictions on the date will become more reliable. NASA is keeping a close watch on the falling satellite, but will only be able to pinpoint its actual crash zone to within about 6,000 miles (10,000 km) about two hours before re-entry.

This week Pew Research released its Internet and American Life Project. Based on their research, virtually all smartphones now include a built-in GPS receiver to enable location tracking, but only 55% of U.S. smartphone owners have used their phone’s GPS system to help get local directions or recommendations.

Pew did not speculate about that other 45%, but I found this to be a very interesting statistic. One of the problems with a smartphone GPS system is that it can be unreliable when you are unable to get a cell phone signal, so those who can afford a smartphone may also be willing and able to spend the cash on a better and more reliable GPS navigation system. Perhaps, the remaining 45% of people who can afford a smartphone either have a handheld GPS device, such as a Garmin Nuvi, or their vehicle has a factory-installed GPS navigation system.

GPS Tracking Without a Warrant – Should It Be Legal?

How would you feel if the police put a GPS tracking device on your vehicle without having a warrant? Without your knowledge, they would be able to track your movements quite well. If the police did this to you in order to gather evidence used to accuse you of a crime, you might rightly feel that your constitutional rights have been violated.

After all, the Fourth Amendment to the U.S. Constitution protects people facing criminal charges in California and across the United States from unreasonable searches and seizures. Logically, you could assume that placing a GPS tracking device on a person’s car without a warrant would be precisely that type of unreasonable search. However, law enforcement authorities would like to be able to do just that. The U.S. Supreme Court recently agreed to take on a case that will address this precise issue.

In 2005, Antoine Jones drove around with a GPS tracking device inconspicuously attached to his Jeep. He had no idea the GPS device was attached to his vehicle. The device recorded the vehicle’s every movement, 24 hours a day, seven days a week, for about 4 weeks total. Law enforcement agents placed the tracking device on his vehicle without first obtaining a court ordered warrant.
