Transcript of The Rosetta Mission

November 8, 2007
Asteroid 2007 VN is "discovered" by an over eager astronomer.
The 20m-diameter asteroid was going to be 5,700 km off the Earth's surface on November 13th.
This led to a terrifying theory that the so-called 'asteroid' would collide with Earth.
Theory actually lasted for a few days until shot down by Denis Deniseko.
He discovered that the 'asteroid' had the exact same trajectory as the
Rosetta
space probe.
Mars Flyby
Launch!
The Rosetta Mission is funded and managed by the European Space Astronomy Centre (ESAC) near Madrid, Spain and built and launched by the European Space Agency (ESA) It is also controlled by the European Space Operations Centre (ESOC) in Germany.
Cost was 1.3 billion Euros ($1.8 billion)
The space probe was set to launch on January 12th, 2003, but a failure of its carrier rocket on December 11 of the previous year delayed it.
The spacecraft, along with its lander the
Philae
finally was launched on March 2nd, 2004.
February 25th, 2007
Rosetta
was slightly off trajectory.
A Mars flyby would slingshot in the right direction.
nicknamed "The Billion Euro Gamble"
out of contact for 15 minutes
Obviously it made it and even took pictures!
Asteroid?
Success!!!
In August 2014, the
Rosetta
rendezvoused comet 67P/Churyumov–Gerasimenko. It made many complex maneuvers to eventually get into a consistent orbit on September 10th.
On September 15th, landing site J, named Agilkia, was chosen to be the landing site for the
Philae.

Landing
Philae sticks a very bouncy landing on November 12th.
It had spent two
hours
bouncing only twice off the surface.
It was only moving at 2.2 miles per hour.
The lander was equipped with harpoons in case the comet got away, but they weren't necessary.
The lander is now commencing the final, 17-month long part of the mission by collecting chemicals to check for signs of life and study of the comets developments.
