Look out below! A defunct satellite is falling back to Earth and is expected to reenter the atmosphere.
After UARS, come ROSAT, now is time for Phobos !
*”November 11 developments*
All efforts to contact Phobos-Grunt proved futile and the attention of the
press was quickly switching to the inevitable uncontrolled reentry of the
spacecraft into the Earth atmosphere, expected sometimes from the end of
November to the middle of December. NORAD reportedly projected the reentry
of the spacecraft on November 26.
According to known technical specifications of the Phobos-Grunt
mission, the 13-ton vehicle contains more than 10 tons of toxic propellants –
unsymmetrical dimethylhydrazine (fuel) and nitrogen tetroxide (oxidizer).
Although most of the fuel and oxidizer would burn during the initial phase
of reentry, the size and mass of the spacecraft practically guarantees that
surviving metal debris would reach the Earth surface. In addition, a
capsule for soil samples designed to survive a hard landing would be
reentering alongside the spacecraft. Due to its insulated design, the
capsule would likely be torn off from the rest of the vehicle early into
the reentry and its impact would likely take place away from the rest of
the debris along the reentry path. The crash could take place anywhere from
51.4 degrees North latitude to 51.4 degrees South latitude.”
Notes from ROSAT:
ROSAT was launched in 1990 and ended it’s mission in 1999:
Notes from UARS:
“And we believe it’s going to be 26 different components that will hit the surface of the Earth somewhere, with a total mass a little over 500 kilograms.”
“Because this is a U.S. government satellite, any object that does reach the surface of the Earth, should it be found, is still the property of the United States,” said Nick Johnson, chief scientist of NASA’s Orbital Debris Program Office at the Johnson Space Center in Houston. “You do not have the luxury of trying to sell it on eBay.”
Any parts found must be surrendered to the government. Pocketing pieces as souvenirs could lead to charges of theft of government property.
If debris rains down outside the country, or splashes down in the ocean and later washes ashore on foreign soil, then the United Nations’ Outer Space Treaty could still offer the U.S. the option of requesting the debris to be returned. Any of the 100 nations that are party to the 1967 convention would be required to comply, though the U.S. would be responsible for any transportation costs.”
