  1. Goldrush in Space Asteroid Mining Jake Pan

  2. What are Asteroids? • Asteroids are chunks of rock floating in space: • Left over from the formation of our solar system • Created when two larger objects collided

  3. Why would l want to mine them? • Asteroids contain: • Metals like iron can be used for construction • Rare metals like platinum • Water for astronauts to drink

  4. Size • A few meters across • 1000 kilometers across • Irregular shapes • A scale image of several different asteroids. The largest, 4 Vesta, has an average diameter of 525 km. The smallest, 25143 Itokawa (barely visible in this image), is an ellipsoid with a length of 630 m and a width of 250 m.

  5. Where are located the asteroids? • The planets' orbits around the Sun are represented by elliptical blue lines, and asteroids are represented by dots. Most of the asteroids are clustered in the "main belt" (white dots), but there are other smaller groups of asteroids.

  6. Which asteroids to mine? • Information from: • The National Aeronautics and Space Administration (NASA) • The Jet Propulsion Laboratory (JPL)

  7. JPL Database • Information about their elliptical orbits around the sun. • Semi-major axis: Earth’s average distance from the sun (measured in astronomical units)(AU) • Perihelion: closest distance to the sun • Aphelion: farthest distance from the sun

  8. Physical Information • C-type: most common type clay and rocks and water 75% • S-type: iron, stony materials, platinum 17% • M-type: metallic, nickel, iron

  9. My Plan • l would mine for asteroids S-type, that are near Earth for platinum • Bring platinum back to Earth and sell it. • Land on large asteroids • Check the shape • Check the spinning speed • Check how soon will be the next approach and distance to Earth • Check how much material my spacecraft could bring back from an asteroid in one trip • Would l have to plan multiple trips back and forth to the same asteroid?

  10. The JPL Small-Body Database Search Engine : list of asteroids

  11. JPL Small Body Database Browser : Data about my asteroid Ceres • Orbital elements

  12. Physical parameters

  13. When it was discovered
