EXPERIENCE THE CHARM OF GRAVITY ASSISTS
Once every 175 years the outer planets of our solar system (Jupiter, Saturn, Uranus, Neptune) line up just so – in a way that allows us to use each planet’s gravity to travel to the next. And that’s just what the Voyager mission did, in the process obtaining some spectacular views of the outer planets in the process.
So if you’re not planning to be around in the 2150s with Captain Jonathan Archer, the Daleks, et al. for the next one, you can still curl up here on Earth and enjoy the concept. Celebrate The Grand Tour from the comfort of your couch. Created by the “Exoplanet Travel Bureau” (aka NASA’s visual strategists), this great faux retro futurism travel poster has been turned into a plush fleece throw. We don’t mean to brag, but it IS the sort of thing that only comes around once every 175 years.
