🥾 Did you know that astronauts hike as part of their training? Hiking has been an element of astronaut survival training since the early 1960s and was part of geological training in the Apollo years. Enjoy these trekking images of @NASA_Astronauts for #NationalHikingDay #NASAhistory

It is #TakeaHikeDay, or #NationalHikingDay
