The 5 ground breaking missions racing to Interstellar Space

Only 5 human-made spacecraft have ever achieved the speed needed to escape our solar system and enter interstellar space. In this cosmic race animation, we map the sheer magnitude of their incredible journeys—from Pioneer 10 to New Horizons—and explore where our solar system actually ends. Discover how legendary NASA missions like Voyager 1, Voyager 2, Pioneer 10, Pioneer 11, and New Horizons utilized the "gravity assist" cosmic slingshot to supercharge their speeds. We also break down the two major boundaries of deep space: the Heliopause (roughly 120 AU away) and the gravitational edge of the Oort Cloud (extending up to 100,000 AU). Learn why New Horizons, despite being the fastest object launched from Earth, will never actually catch up to the Voyagers! 👇 Which legendary space mission do you think is the most important?
