Rendezvous with Rosetta By: Zahra Mirzaiyan Solar System, Kuiper belt & Oort cloud Solar System, Kuiper belt & Oort cloud • Distance from sun: 4.8 Billion Km • Size: 3.2 billion km • Material & Shape: flat disk of icy debris and much larger objects as big as the moon and Pluto, that lies in the same plane as the orbits of the planets Solar System, Kuiper belt & Oort cloud • Distance from Sun: 30 Trillion km! • Size: Completely surrounding Solar System! • Material & Shape: The Oort Cloud is not disk-shaped like the Kuiper Belt; it’s round like a ball,It completely envelops the sun and the rest of our solar system. Billions of icy bodies pass through this enormous celestial ballroom as they weakly orbit our sun. Why Comets? Comet 67P/Churyumov–Gerasimenko • • • • Origin: originally from the Kuiper Belt Orbital Period: 6.45 years Velocity: 38Km/s Size: approximately 4.3X4.1km The Rosetta Probe and the Lander “Phliae” • Origin: built & Launched in 2004 by ESA • Size & Weight: 2.8X2.0X2.1m & 2.9 Tons • Mission: studying the Comet remotely and by the lander “Philae” Mission overview • Duration: appx 10 years • Goals: Landing Philae on surface, taking samples, analyzing and sending back Data In Action & Breakthroughs • During Touch down, two critical instruments for sticking and stabilizing Philae on surface went impaired. Philae hit the surface and bounced back, hovering for hours. Finally it landed in an area with less sunlight to recharge its batteries. Fortunately its initial battery charge could do for the first samplings, analyzing and data sending back giving scientists significantly important information. • From the data analysis scientists could find Organic carbon based Molcules on the surface of the Comets. It actually could find the seeds of life! • Spectrometry from rosetta itself could find out that the ratio of Deuterium to Hydrogen is higher than which exists on earth. The Rosetta Stone • Created: 196 BC • Discovered: 1799 • Size: 114.4 × 72.3 × 27.93 cm Thank You
