Placed for more than two years in a gravitationally stable point between the Earth and sun, the spacecraft collected charged particles streaming out from the sun, called the solar wind. NASA's Genesis spacecraft delivered the first samples from beyond the orbit of the moon in 2004.

This finding led scientists to theorize that the moon formed from rock and metal that flung off a collision between a young Earth and a Mars-size object about 4.5 billion years ago.Īn artist’s rendering of solar wind, which is a stream of charged particles continually released from the sun. Among many other things, Apollo samples revealed that the makeup of the moon and Earth are so similar the two likely formed from the same material. Apollo astronauts collected and returned 842 pounds (382 kilograms) of rocks and dust across six missions.īecause moon rocks are better preserved than Earth rocks, they offered unprecedented insight into how our planet and solar system formed-a history largely erased on Earth by erosion, climate cycles, volcanic activity, and plate tectonics. It also launched a new era of science, engineering, and exploration. NASA astronaut Neil Armstrong's famous line, 'That's one small step for man, one giant leap for mankind,' commemorated humanity's first footsteps on a world beyond Earth. Here is an overview of the history and future of missions, organized by NASA and its partners, to bring home pieces of space.ġ969: NASA's moonwalk delivers first space samples Many more sample-gathering missions to the moon and beyond followed, growing in ambition with each passing decade.

The practice of retrieving samples from space began in 1969 with NASA's Apollo 11 mission, the first to land astronauts on the moon.
