Try Astronaut Grapes for something completely different. Enjoy your fruits just as the Astronauts do: the freeze-dried way! These fruits aren’t dried like traditionally preserved foods. Instead, the moisture is removed completely through the freeze-drying process. This leaves the final treat weighing nearly nothing… which is critical when trying to reach the stars! Freeze dried food items have been aboard space missions since the early Mercury Missions. They continue to be used on NASA missions today. You may not ever get to the stars, but you can treat yourself to a starry, healthy snack.
