A propos de cet article

1 Sheet, 11 inches by 8.5 inches, printed on both sides. Item has some wear and soiling, especially at edges. Timeline. A sample return mission is a spacecraft mission with the goal of collecting and returning with tangible samples from an extraterrestrial location to Earth for analysis. Sample return missions may bring back merely atoms and molecules or a deposit of complex compounds such as loose material ("soil") and rocks. NASA's OSIRIS-REx mission is the first U.S. mission to retrieve a pristine sample of an asteroid and return it to Earth for further study. The mission's target is Bennu, a carbon-rich near-Earth asteroid that is also potentially hazardous to Earth. Asteroids are the leftover debris from the Solar System's formation process that began more than 4.5 billion years ago. Studying Bennu will revolutionize our understanding of the early Solar System and teach us much about planetary history and the origin of life. The OSIRIS-REx mission will expand our knowledge of the hazards and resources in near-Earth space and will serve as a precursor to future asteroid missions. OSIRIS-REx was scheduled to be launched on September 8, 2016 from Space Launch Complex 41 at Cape Canaveral Air Force Station, FL. OSIRIS-REx seeks answers to the questions that are central to the human experience: Where did we come from? What is our destiny? Asteroids, the leftover debris from the solar system formation process, can answer these questions and teach us about the history of the sun and planets. The OSIRIS-REx spacecraft is traveling to Bennu, a carbonaceous asteroid whose regolith may record the earliest history of our solar system. Bennu may contain the molecular precursors to the origin of life and the Earth's oceans. Bennu is also one of the most potentially hazardous asteroids, as it has a relatively high probability of impacting the Earth late in the 22nd century. OSIRIS-REx will determine Bennu's physical and chemical properties, which will be critical to know in the event of an impact mitigation mission. Finally, asteroids like Bennu contain natural resources such as water, organics, and precious metals. In the future, these asteroids may one day fuel the exploration of the solar system by robotic and manned spacecraft. MISSION OBJECTIVES OSIRIS-REx's key science objectives include: Return and analyze a sample of Bennu's surface Map the asteroid Document the sample site Measure the orbit deviation caused by non-gravitational forces (the Yarkovsky effect) Compare observations at the asteroid to ground-based observations.…
