Explorer 2 was the second satellite in the Explorer program , which is the first and most extensive program of satellites and spacecraft in the United States. The flight was essentially intended to be a repeat of the successful Explorer 1 mission . However, the 4th stage of the Juno I launcher failed to fire, preventing the satellite from reaching orbit .
Explorer 2 was equipped with a Geiger counter for measuring cosmic rays and an apparatus for detecting micrometeorites.
