Short answers, pulled from the story.

When did Pioneer 6 launch from Cape Canaveral?

Pioneer 6 launched on the 16th of December 1965 from Cape Canaveral. It was part of a series designed to measure solar wind and magnetic fields.

What instruments did Pioneer 7 carry during its mission?

Each probe carried a suite of sensors including magnetometers and plasma analyzers. The Solar Wind Plasma Faraday Cup measured positive ions and electrons in the solar stream while Cosmic-Ray Telescopes detected high-energy particles arriving from galactic sources.

How far did Pioneer 8 orbit from the Sun after launching on the 13th of December 1967?

Pioneer 8 achieved a mean distance of 1.1 AU from our star after launching at 14:08 UTC from Cape Canaveral. This orbit placed it alongside other probes in distinct heliocentric paths between 1965 and 1968.

Why is Pioneer 9 significant for solar storm monitoring in August 1972?

In early August 1972 Pioneer 9 recorded significant observations of one of the most potent solar storms ever recorded. That event proved the most hazardous to human spaceflight during the Space Age.

When did Pioneer 6 lose contact with Earth after operating for over thirty-five years?

Pioneer 6 operated for over thirty-five years before losing contact in 2000. A successful telemetry contact occurred on the 8th of December 2000 to celebrate 35 years of continuous operation.
