The Full Story
NASA’s Mariner 2 became the first spacecraft to successfully fly by another planet when it passed Venus in December 1962. This was a landmark in robotic exploration because it proved that interplanetary flybys were possible. Mariner 2 measured Venus’s temperature and atmosphere and helped confirm that the planet was far hotter than expected. Its success opened the way for later planetary missions.
