International Space Station program ocean was found to be possible only with Russia's assistance. At the time ISS was launched, the Russian Space Agency had experience from de-orbiting the Salyut 4, 5, 6, and 7 space stations, while NASA's first intentional controlled de-orbit of a satellite (the Compton Gamma Ray Observatory) would not occur for another two years. NASA currently has no spacecraft capable of de-orbiting the ISS at the time of decommissioning. Skylab, the only space station built and launched entirely by the US, decayed from orbit slowly over 5 years, and no attempt was made to de-orbit the station using a deorbital
New Norcia Station New Norcia Station New Norcia Station (also known as NNO) is an ESTRACK Earth station in Australia for communication with spacecraft after launch, in low earth orbit, in geostationary orbit and in deep space. It is located south of the town of New Norcia, Western Australia. It was the first ESA deep space ground station, followed by Cebreros Station and Malargüe Station. The station operates one 35-meter dish designated NNO-1 capable of two-way transmission in both S- and X-bands using 2 and 20-kilowatt transmitters. The antenna weighs over 600 tonnes and is 40 metres tall. Future upgrade plans include adding
