Armstrong and Rock Box

Apollo 11 commander Neil Armstrong works with an Apollo Lunar Sample Return Container during a two-and-a-half-hour lunar surface simulation training exercise. The image was taken on Apr. 18, 1969, in Building 9 at the Manned Spacecraft Center in Houston, Texas. The sample tubes carried by NASA's Mars 2020 Perseverance rover are destined to carry the first samples in history from another planet back to Earth.
