  Pioneer 10 - Wikipedia, the free encyclopedia
Pioneer 10 was the first spacecraft to travel through the asteroid belt, and was the first spacecraft to make direct observations of Jupiter.
Pioneer 10 was also outfitted with a plaque to serve as a message for any extraterrestrial life, in the event that it may be discovered.
Pioneer 10 is heading in the direction of the star Aldebaran in the constellation Taurus.

 Pioneer 10 & 11
The third stage was required to rocket Pioneer 10 to the speed of 51,810 kph needed for the flight to Jupiter.
During the passage by Jupiter, Pioneer 10 obtained the first close-up images of the planet, charted Jupiter's intense radiation belts, located the planet's magnetic field, and discovered that Jupiter is predominantly a liquid planet.
As of February 1996, Pioneer 10 was at a distance of 9.5 billion kilometers from Earth.

 Pioneer plaque - Wikipedia, the free encyclopedia
On board each of the unmanned spacecraft Pioneer 10 and Pioneer 11 is a plaque with a pictorial message from mankind.
The original idea, that the Pioneer spacecraft should carry a message from mankind, was first mentioned by Eric Burgess when he visited the Jet Propulsion Laboratory, Pasadena during the Mariner 9 mission.
The first plaque was launched with Pioneer 10 on March 2, 1972, and the second followed with Pioneer 11 on April 5, 1972.

Pioneer 10 reached a speed of 32,400 mph needed for the flight to Jupiter, making it the fastest human-made object to leave the Earth; fast enough to pass the moon in 11 hours and to cross Mars' orbit, about 50 million miles away, in just 12 weeks.
Pioneer 10 was the first spacecraft to pass through the asteroid belt, considered a spectacular achievement, and then headed toward Jupiter.
Pioneer 10 explored Jupiter, traveled twice as far as the most distant planet in our solar system, and as Earth's first emissary into space, is carrying a gold plaque that describes what we look like, where we are, and the date when the mission began.

 Pioneer 10, 11 Quicklook
Pioneers 10 and 11 were the first spacecraft to visit Jupiter (Pioneer 10 and 11) and Saturn (Pioneer 11 only).
Pioneer 11's mission ended on September 30, 1995 when its RTG power level was insufficient to operate any experiments and the spacecraft could no longer be controlled.
Pioneer 10 is expected to operate until sometime in 1997 when its power levels are also expected to fall below the minimum required levels.

 The Perils of Pioneer 11
Pioneers 10 and 11 were originally conceived in 1969 as small, simple, spin-stabilized spacecraft for humanity's first venture into the outer Solar System.
The Pioneers would be the first spacecraft to fly through the asteroid belt; there was no significant chance of hitting a large asteroid, but hitting a few hundred grains of sand would be almost as bad, and nobody knew how many small particles might lurk undetected in the belt.
Pioneer 11's primary mission was to be the backup for Pioneer 10 -- if Pioneer 10 failed before completing its Jupiter flyby, Pioneer 11 would repeat that flyby.

Pioneer 10, missing, feared dead for eight months, was phoning home to let scientists know that it was still alive and kicking.
But, as Lasher notes, "in retirement Pioneer 10 still served the public as a valuable space resource at no extra cost to the taxpayers." It has been used to train spacecraft controllers in tracking station protocol and continues to be tracked as a part of study in communication technology.
One of the greatest surprises raised by the original Pioneer mission was, according to Lasher, the persistence of the solar wind, the stream of charged particles that radiates from the sun.

 Study of the Anomalous Acceleration of Pioneer 10 and 11
This paper shows that the anomalous acceleration of the spacecraft Pioneer 10 and 11 in the direction of the Sun is due to the presence of dust in the Kuiper belt, which has been ignored in the calculation.
AU), when the Pioneer 10 and 11 spacecraft are in the Kuiper belt and move through it, we observe, as should be expected, that they move at an almost constant velocity in a direction away from the sun.
That change of momentum of Pioneer 10 is due to the collision with dust in the Kuiper belt.

 Pioneer 10 & 11 - Abstract
Pioneer 10, which was launched in 1972, was the first probe sent to the outer planets.
Before Pioneer 11 was launched, the gain and threshold settings of its starlight sensor were modified to improve performance on the basis of experience gained during the first few months of Pioneer 10's flight.
Pioneer's path was calculated by use of celestial mechanics, and the radio data provided information to keep the trajectory updated and to determine the masses of planetary bodies the Pioneers encountered.
