Arago: Space Issues

Space Issues

The Space issues of this period commemorated the astrological and rocket science advances gleaned from the 1972 and 1973 probes of Pioneer 10 and Mariner 9. These probes greatly increased our understanding of our solar system and its planets. Each probe reached its own milestone: Pioneer 10, launched on March 2, 1972, was the first spacecraft to travel through the asteroid belt (between the orbits of the planets Mars and Jupiter); Mariner 9, launched on November 3, 1973, was the first spacecraft to make use of an interplanetary 'gravitational slingshot.'
