The Aerocene Float Predictor uses wind forecast data from the US NOAA Global Forecast System, inviting visitors to generate their own fossil fuel
free flight trajectories around the world, based on the wind patterns each day.
The Inspiration Mars mission will use what's known as a
free - return
trajectory to Mars — a special
trajectory that is only available twice every 15 years, where the gravitational fields from the planets perfectly align for a quick and cheap
flight to Mars and back.
