Astrophobia is the fear of outer space. It can take many forms, from a fear of the stars to a fear of space travel.
One example of the later is actress Jessica Chastain, who starred in the movie Interstellar. When Hollywood Reporter asked Interstellar cast members if they would personally like to go into space, Chastain was the only one who said no — quite emphatically.
Yet, NASA chose Chastain to narrate this new advertisement for its Orion program.
Based on official plans, Orion will carry only four astronauts into space, once every two years — the lowest flight rate since Project Mercury. It would appear that NASA, like Chastain, has a fear of flying in space [very often].
