When Robert Behnken and Douglas Hurley lift off from Kennedy Space Center to the International Space Station, Nasa will be hoping they will both break tradition and set a new course for US spaceflight.
They flew during the Space Shuttle years and have been tasked to begin a new level of space travel to the ISS (International Space Station).
They will spend roughly 3 months aboard the ISS and then splash down back in the Atlantic just like the old days. See a test flight below.
