http://spaceprojects.arc.nasa.gov/Space_Projects/pioneer/PNStat.html<br /><br />STATUS UPDATED: 1 February 2003 <br /><br />Pioneer 10 <br /><br />Distance from Sun : 82.19 AU <br />Speed relative to the Sun: 12.224 km/sec (27,345 mph) <br />Distance from Earth: 12.21 billion kilometers (7.59 billion miles) <br />(Round-trip Light Time 3D 22 hours 38 minutes) <br /><br />The Pioneer 10 signal was detected on 23 January 2003, but because of <br />limited link time (due to a high-power transmitter trip) no telemetry was <br />received. During uplink on 22 January 2003, the high-power transmitter <br />tripped off. A second high-power transmission was limited to a short time at <br />the end of the track. A GTT-off command was radiated. During downlink on <br />23 January 2003, the signal was found but there was no lockon to the <br />subcarrier. (Roundtrip Light Time was 22 hours 35 minutes). <br /><br />On 5 December 2002, there was a Pioneer 10 contact. The Deep Space Station<br />(DSS) near Madrid (DSS-63) found the signal but could not lock onto the<br />receiver, and so no telemetry was received. The signal level was just under<br />the threshold value. The uplink from DSS-14 at Goldstone, sent 4 December<br />2002, at a power level of 325 kw, confirmed that the spacecraft signal <br />is still there (Round Trip Light Time 3D 22 hours 24 minutes). <br /><br />Project Phoenix also picked up the signal at Arecibo in Puerto Rico.
