[QUOTE="Analoguesat, post: 158585, member: 176362"] Older members will remember the Pioneer 10 & 11 missions - shot out into space in the mid 1970's they returned the first close up pics of Jupiter. They were tracked and monitored until 2002 with occasional success in downloading telemetry from 10. Increasing distance (P10 is 87AU out now) and the slow decay of the nuclear reactors on board led to the last attempt at contact in 2003 failing. P10 was tracked for 7.6 billion miles(!) and has now travelled 8 billion miles and it travelling at over 27000 mph...... _http://spaceprojects.arc.nasa.gov/Space_Projects/pioneer/PNhome.html There will be one last effort on March 6th to contact Pioneer 10 and this really is the last chance - the spacecraft trajectory will soon mean that the antenna is no longer pointing at the Earth. _http://www.planetary.org/programs/projects/pioneer_anomaly/update_200511.html Incredible all but one of the earlier Pioneers which were launched in the mid 1960's were nominally partially operational into the mid 1990's [/QUOTE]
