Two recent finds of satellite fuel tanks - both of carbon-wrapped titanium fuel tanks from the Atlas Centaur upper stages of two US military satellite launches probably - are in the news at the same time. One came down a week ago in Brasil, the other was found in the autumn of 2007 in Australia.

The Brasilian fuel tank is very likely part of the upper Centaur stage of the rocket that launched a US military communications satellite (Global SATCOM, 2007-046B) in October 2007. The Australian fuel tank could be a part of the upper Centaur stage of the rocket that launched another military satellite, USA 138 (1998-016A) in 1998.
