Beyond the world we know is space;
a universe full of a million possibilities,
accompanying our exploration in this universe.
When i first heard the idea of Rosetta
I felt it would be extremly difficult
We arrive at a comet, we don't flyby.
We stay there, we oribiting
Non of this has ever been done before.
10 years and two months after it has started on March 2, 2004...
...the ESA spacecraft reached Comet Churyumov-Gerasimenko.
The snow here on Earth,...
...all the water on earth...
...might have come from comets.
We think there are organic molecules on comets.
And the comets from somewhere out there...
...brought the basic building blocks of our life...
...to the primitiv earth as well.
It's the first time...
...that a space craft has flown so far from the sun using solar panels.
Rosetta's solar generator is now only providing as slow amount of electricity.
It is primarily used to warm the probe enough...
...so that the elctronic equipment and scientific instruments where not damaged by the low tempretures.
After a series of maneuvers the Rosetta spacecraft orbit...
...the comet in a constant distance of 100 and 50 kilometres on August 6th 2014.
Phiele is a Lander that will separate from it's parents space craft in 2014.
Land on a target in commentary region and carry out a complete measurement program.
To get the speed and the right direction to the comet,...
...Rossetta had to be perform three flyby’s from Earth to get its direction,...
...one flyby to Mars in 2007 to correct the trajectory and two flyby’s to asteroids in 2008 and 2010 to fine-tune the trajectory.
Followed by a 31-month hibernation mode until January 2014 where the approaching sequence started.
Rosetta’s Mission was controlled from the European Space Operations Centre in Darmstadt, Germany.
It was further planed, claibrated and distributed from the European Space...
...Astronomy Centre in Villanueva de la Cañada, near Madrid in Spain.
Hello and welcome inside the main control room which is quite exciting.
We also get a good view of the countdown clock here before Rosetta will wake up.
It requires 45 minutes for the signal to travel with the speed of light...
...to come from the space craft to us.
The Rosetta mission was generational project.
During the 10 years flight time of Rosetta, more than 2,000 people were assisting the mission.
Rosetta spacecraft consists of the Rosetta orbiter with 12 scientific instruments...
...and the Philae lander with nine additional instruments.
The hope of Mission was to get a better understanding of comets and the early solar system.
Over the time of the mission a generational team management was established...
...with alloed mission continuity and the transfer of knowledge to future and younger team members.
Named by the Rosetta stone,...
...a stele of Egyptian origin featuring a decree in three scripts and...
...by the Philae obelisk,...
...which bears the bilingual Greek and Egyptian heroglyphic inscription.
In this sense, Rosetta carried a disc with a translation of 6,500 pages in different languages.
It was the first spacecraft to fly alongside a comet as it...
...headed towards the inner Solar system and...
...examine at close proximity the activity of a frozen comet as it is warmed by the Sun.
A magnetic field around the comet was found, but not longer detected on the comets nucleus.
The lander sent incredible footage back to the orbiter...
...before its battery power was empty and its exact position was unkown.
Because of its unkown surface, the orbiter mapped the comet to find the perfect landing position.
In Berlin we have biult three instruments for this Lander.
The roles camera on the buttom of the lander...
...will aquire 607 images that will reach earth hours later.
The Mufus device will be hammered into the surface to measure the thermal properties.
These will be then refine using the other instruments to...
...understand which kind of environment landed on.
It wasn't like this great potato that we first imagined.
That it was actually much more interesting.
It consists of two parts.
This double structure was not expected and we all have the same initials thought.
How will we will land on this.
It hasn't made things any easier.
It's a massive challenge, technologicly.
But on the same time, the reason we are at this comet is for science.
No other reason!
We're doing this to get the best size to characterize this comet...
...as has never been done before.
After considering of all the different aspects of the possible landing sites.
We have decided on landing site J.
We've also selected an alternative landing site C on the body.
Philae successfully made the first soft landing on a comets nucleus when it touched down on November 12th 2014.
Philae bounced twice on the comets surface until...
...two harpoons were fired into the comet to prevent the lander from bouncing off,...
...as the comet's escape velocity is only around 1 m/s.
Almost 2 years the ESA was looking for the position of Philae until they announced that the lander was discovered.
The lander was canted at an angle of around 30 degrees into a dark crevice of the comet,...
...explaining the lack of electrical power to establish proper communication with the orbiter.
The orbiter reached Philae again on June 13 and July 9 2016,...
...before contact was lost once again.
There was no communication afterwards and...
...the transmitter to communicate with Philae was switched off in July 2016.
On his mission the Rosetta spacecraft achieved some historic firsts.
It was the first European spacecraft passing the asteroid belt and...
...to operate a flyby close to Jupiters orbit using solar power.
Only competed by the successful touchdown of the Philae lander on the comet.
Rosetta and Philae’s instruments searched for organic molecules,...
...nucleic acids (the building blocks of DNA and RNA) and...
...amino acids (the building blocks of proteins) by samepling and...
...analysing the comet’s nucleus.
The only amino acid detected thus far is glycine,...
...along with the precursor molecules, namely, methylamine and ethylamine.
Sixteen organic compounds, four of which were seen first time on a comet,...
...including acetamide, acetone, methyl isocyanate and propionaldehyde were found on the comet.
The comets nucleus contains only little to no water ice visible.
The water that was found suggests that water on Earth was not coming from comets.
First analyses strongly suggest that carbon is present as polyaromatic...
...organic solids mixed with sulfides and iron-nickel alloys.
The carbon in this organic material is bound in "very large macromolecular compounds".
The most outstanding discovery was the detection of...
...large amounts of free molecular oxygen gas surrounding the comet.
The the significant results found from the mission has to be analysed by scientists in the next decades.
After 17 months of orbiting the comet Churyumov-Gerasimenko,...
...the European space probe completed the most detailed study of a comet in human history.
On September 28th 2017, a previously unrecovered image taken by the spacecraft...
...was reported and recovered after completion of the mission.
It is the closest image from the surface of the comet,...
taken from a distance of 17-21 meters and just shows one square meter of the comets surface.
On September 29th 2016 the descent of Rosetta orbiter...
...to the surface of Comet Churyumov-Gerasimenko began.
The orbiter impact 14.5 hours later on the surface in the Sais region.
No other mission in ESA’s history was so heavily featured on social media.
