Pioneer P-3

Pioneer P-3 was the second of a planned series of four lunar probes of the U.S. Space Agency NASA as part of the Pioneer program. You should pivot into a high orbit around the moon and take pictures of the surface, as well as other conduct experiments. Just 45 seconds after launch broke the payload fairing, which led to an unstable trajectory of the rocket, and finally the total loss. Since the mission, as well as the three other missions, was a failure, she received for reasons of confidentiality no numbering but only one letter.

Construction

Pioneer P- 3 had a spherical shape with a diameter of 1 meter. After deployment of the solar panels, they would have had a wingspan of 2.7 meters. The probe contained a number of measuring instruments, including a micro- meteorological ride detector, a Geiger- Müller counter, a proportional counter, a sun detector and an ionization chamber. For the thermal regulation of Pioneer P-3 should contribute 52 small propeller blades. This would have opened when the temperature of the probe to cool to raise by sunlight, the temperature of the probe. Too much temperature they had closed again.

Mission

It was planned that the probe should be delayed after reaching the moon by Braking rockets, thereby entering into a lunar orbit. Because of the destruction of the probe at the start of the mission was a total failure.
