NASA Makes Contact With Pioneer

Even though it's a distant 11.9 billion kilometres away, Pioneer 10 is still coming in loud and clear. NASA scientists sent a message to the spacecraft from California using the agency's Deep Space Network and received a reply just over 22 hours later at a dish in Spain. This communication occurred on the 30th anniversary of the spacecraft's launch.
