Pioneer Plaque

March 2

1998 Data sent from the Galileo spacecraft indicates that Jupiter's moon Europa has a liquid ocean under a thick crust of ice.

1972 - Pioneer 10 (USA) launched on an Atlas/Centaur rocket. It become the first probe fly through the asteroid belt and on to the planet Jupiter (in 1973). Pioneer 10 carries a plaque designed to identify its origin should the probe be encountered as it drifts through the Milky Way galaxy. Pioneer 10 is still returning data as of March 1999, and is 10.81 billion kilometers (6.716 billion miles) from Earth. 27 years after the launch the real-time tracks of Pioneer 10 are being used to train spacecraft controllers in tracking station protocol and data archiving procedures.
