Juno II was a launch vehicle developed by America's space program to enable boosting larger scientific payloads into space. The modified Jupiter C (sometimes called Juno I) that was used to launch Explorer I had minimum payload lifting capabilities, as Explorer I only weighed 31 pounds.
Juno II successfully launched a Pioneer IV satellite on March 3, 1959, and an Explorer VII satellite on October 13, 1959. Pioneer IV passed within 37,000 miles of the [[moon]] before going into permanent solar orbit. Explorer VII had a total weight of 91.5 pounds and carried a scientific package for detecting micrometeors, measuring the Earth's radiation balance, and conducting
other experiments.
On November 3, 1960, a Juno II sent Explorer VIII into a 1,000-mile deep orbit within the ionosphere. In 1961, Juno II launched an 82-pound satellite into orbit to conduct a complex gamma-ray astronomy experiment.
Subsequently improved launch vehicles replaced the Juno II as the primary launcher for the Explorer satellite series.
