The last successful contact was made with the spacecraft Pioneer 10, one of the most distant man-made objects in the universe. Pioneer 10 is heading in the direction of the star Aldebaran in the constellation Taurus at roughly 2.6 AU per year. If Aldebaran had zero relative velocity, it would take Pioneer 10 about 2 million years to reach it.

Since that time, thanks in part to their use of computer technology, Butler and Marcy have become known as “the world’s most successful planet hunters”.
Telstar 401, a satellite owned by AT&T that transmitted computer data, phone calls, and television programming, suddenly fails for no apparent reason. AT&T attempts for over a week to reestablish contact, but ultimately fails. While AT&T never officially acknowledges the possibility, many scientists believe that a major solar storm may have contributed to the failure of the satellite.
