in which the engines would work in parallel (packet) in order to achieve a greater flight range. His announcement was met with ridicule and skepticism by his scientific colleagues because at that time, it was believed that 1000 km was the absolute limit for rocket range. In NII-4 he led a team of researchers that did important studies on packet rockets, satellite orbital motion, optimal pitch control programs for launching into orbit, reentry trajectories and heat shielding. This team designed Sputnik-3, Luna-1, Luna-3, Luna-4 and the early Venus and Mars probes. In 1956,
