Spacecraft escaping the Solar System

The folowing charts show you the current positions of the four spacecraft: Pioneer10, Pioneer11, Voyager1 and Voyager2 which are leaving the Solar System. Pioneer 10 distance from Sun : 82.39 AU Speed relative to the Sun: 12.222 km/sec (27,340 mph) Distance from Earth: 12.31 billion kilometers (7.65 billion miles) (Round-trip Light Time = 22 hours 49 minutes)

After over 30 years, it appears that Pioneer 10 has sent its last signal to Earth. The power source on Pioneer 10 finally degraded to the point where the signal to Earth dropped below the threshold for detection in its latest contact attempt on 7 February 2003. No more attempts at contact are planned at this time. The previous three contacts had very faint signals with no telemetry received. Pioneer's last, very weak signal was received on 23 January 2003. The last time a Pioneer 10 contact returned telemetry data was on 27 April 2002.
