R0SETTA MISSION

SABONTU H. & REESE H.  3/25/15  P6

-Rosetta is a spacecraft on a 10 year mission to catch a comet ''67P/churyumov-Gerasimeko''

-Rosetta will be the first spacecraft to soft-land a robot on a comet also the first       spacecraft to accompany a comet as it enters our inner solar system,observing at close  range the comet changes as the Sun's heat transforms into luminous apparition that  has frightened and inspired people for centuries.

MAIN GOAL:To catch a comet and help translate older language of comets and thermal signature.

MISSION OCCURRED:March 2,2004-December 31,2015

TECHNOLOGY/EQUIPMENT: Philae Oblisk (look in fun facts section)

-It is an unmanned mission

-The Rosetta spacecraft is named after the ancient Rosetta stone that you can visit today in London's British Musuem.

-The Philae Lander is named after Philae Obelisk which provided the key to our first understanding of Egyptian Hieroglphics.

-In January 2014 Rosetta fired against its engines position

  • On March 4, 2005, Rosetta caught up with Earth and executed the first of its four gravity assists (three from Earth and one from Mars). This first gravity assist hurled Rosetta toward Mars for its meeting in 2007.
  • En route to Mars, Rosetta's instruments analyzed the collision between Deep Impact's impactor and comet Tempel-1 on July 4, 2005.
  • In February 2007, Rosetta executed a close flyby of Mars, which provided the gravity assist it needed to loop back toward Earth for a second flyby in November 2007.
  • In November 2007, Rosetta executed its second Earth flyby, gaining the gravity assist it needed to pass Mars' orbit and reach the asteroid belt.
  • On September 5, 2008, Rosetta passed within 1700 km of asteroid Steins, enabling its instruments to closely observe the flying rock.
  • In November, 2009, Rosetta swung back for a final boost from Earth’s gravity to return again to the asteroid belt.
  • On July 10, 2010, Rosetta flew within 3000 km of asteroid Lutetia, and again used its instruments to observe at close range this asteroid, ten times larger than Steins.
  • By May, 2011, Rosetta was coasting through areas in the outer solar system where the sun is almost a billion km away. At that distance, Rosetta’s solar panels are not able to gather much energy from the Sun, so the spacecraft shut down most electrical activities and will hibernate until comet C-G returns from its long transit in the outer solar system.
  • In January 2014, Rosetta will fire its engine to position itself next to comet C-G in May 2014 as it comes hurtling by. Rosetta will release the Philae for a controlled soft landing on the comet. The Philae will then transmit critical data from the comet’s surface for relay back to Earth. Philae will use harpoons to anchor itself to the comet.
  • After escorting comet C-G past its perihelion (closest point to the Sun), Rosetta will terminate its mission.
