The 7 Coolest Active Space Probes

TL;DR

Explore seven of the coolest active space probes like Opportunity, Juno, ACE, Dawn, Kepler, and Voyager I & II.

Transcript

Since Sputnik 1 launched the Space Race in 1957, we’ve sent thousands of things into space. Lots have spent their entire lives orbiting Earth from communications satellites to the International Space Station and the Hubble Space Telescope. But others have gone a lot farther away, and today, there are way too many active probes out there to fit in a... Read More
