For nearly 60 years, humankind has been sending satellites, probes, spacecraft and even some of our own to space as part of a journey to understand the universe and our place in it. For much of that time, the Energy Department and its National Labs have been supplying the space power systems and instruments that make those missions, and the discoveries they uncover, possible.

Our latest infographic, Spaced Out, shows just where in our solar system Energy Department technology has been used. Your journey begins at the sun, where a radioisotope power system enabled the Ulysses spacecraft to study the space environment above and below the poles of our sun for the first time, and ends at the edge of our solar system — where Voyager 1, powered by another type of radioisotope power system, recently became the first human-made object to venture into interstellar space. In between, learn about the missions, past and present, that are pushing the boundary of that final frontier — outer space.
