But Where Did It Land? We wondered who would have to pay for repairs if it landed on a house. But don't even think about keeping a piece for yourself. The satellite has been slowed down by a change in its orientation. Scientists won't be able to determine where pieces of the UARS satellite will fall until two hours before impact.
The UARS anticipated fall to Earth is almost six years after the end of a productive scientific life. Although the spacecraft will break into pieces during re-entry, not all of it will burn up in the atmosphere. It is impossible to pinpoint just where in that zone the debris will land, but NASA estimates the debris footprint will be about miles long. The UARS satellite, launched in from the Space Shuttle, was the first multi-instrumented satellite to observe numerous chemical constituents of the atmosphere with a goal of better understanding atmospheric photochemistry and transport.
Ooh, cannot wait for the re-entry; sounds exciting and definitely worth checking up on. Good luck!!

Launched from the Space Shuttle Discovery on September 15, , the seven-ton spacecraft orbited the Earth more than 78, times, using 10 onboard scientific instruments to collect data on a variety of chemicals, including carbon dioxide, ozone, chlorine, methane, nitrogen oxides and chlorofluorocarbons. As a result, scientists have gained a better understanding of the energy input, chemistry and dynamics of the upper atmosphere and the coupling between the upper and lower atmosphere.
UARS also measured winds and temperatures in the stratosphere, as well as the energy input from the Sun, research that is now being applied to improve weather forecasting models and help scientists understand the forces behind global climate change.
Before UARS, little was known about the atmospheric region between 80 kilometers and kilometers above the Earth, since radio-equipped balloons would explode at that altitude, and ordinary satellites burn up. UARS orbited at a safe kilometer altitude, aiming its cameras at the atmosphere below. Although the mission was originally intended to last only 3 years, its deployment was long enough to observe an entire year solar cycle.
Data collected from UARS offered conclusive evidence that chlorine in the atmosphere - originating from human-produced chlorofluorocarbons - is at the root of the ozone hole. In all, the ten UARS instruments have provided the most complete data on upper atmospheric energy inputs, winds, and chemical composition ever gathered.
Together, these observations constitute a highly integrated investigation of the nature of the upper atmosphere, and help define the role of the upper atmosphere in climate and climate variability.
In its first two weeks of operation, UARS data confirmed the polar ozone-depletion theories by providing three-dimensional maps of ozone and chlorine monoxide near the South Pole during development of the ozone hole.
Moreover, UARS collected data on the chemistry, dynamics and radiative inputs to the upper atmosphere far beyond its designed lifetime. UARS was designed to last 18 months, but upgrades extended its life for years beyond its expected lifespan.
