Rosetta landing site choices
Published on Sep 12, 2014

On 15 September the Rosetta mission will announce the primary and back up landing sites for comet 67P/Churyumov-Gerasimenko.
This video reviews the five shortlisted landing sites, why they were selected and how the comet’s unusual ‘duck’ shape affected the choice.
The Rosetta orbiter has been studying the comet since May and choosing the right place to land is crucial in order to examine the comet further. The orbiter’s data – together with that from the Philae lander – will provide unprecedented insights into our solar system.
The film also covers the preparation by scientists, members of the mission control team at the European Space Operations Centre at Darmstadt, in Germany, and the challenges ahead.

Philae’s descent and science on the surface

Annotated version of the Philae’s mission at comet 67P animation.
The animation begins with the deployment of Philae from Rosetta at comet 67P/Churyumov–Gerasimenko in November 2014. It will take several hours for it to reach the surface. Because of the comet’s extremely low gravity, landing gear will absorb the small forces of landing while ice screws in the probe’s feet and a harpoon system will lock the probe to the surface. At the same time a thruster on top of the lander will push it down to counteract the impulse of the harpoon imparted in the opposite direction.
Once it is anchored to the comet, the lander will begin its primary science mission, based on its 64-hour initial battery lifetime. The animation shows a number of the science instruments in action on the surface.
Rosetta’s Philae lander is provided by a consortium led by DLR, MPS, CNES and ASI.

The Rosetta mission is ongoing at comet 67P/Churyumov–Gerasimenko. The landing site for Philae has been chosen. The adventure continues! But already Rosetta is providing the scientific community more than any previous comet mission.

Rosetta - A Lesson on Comets
Published on Oct 10, 2014
Quote:
On October 9, as part of the Von Karman Lecture Series at NASA’s Jet Propulsion Laboratory, Manager of the US Rosetta Project, Art Chmielewski discussed comets and how they have inspired awe and wonder since the dawn of history. In November, the Rosetta spacecraft will attempt to become the first spacecraft to soft-land a robot on a comet – named 67P/Churyumov–Gerasimenko. The ten year Rosetta mission seeks to learn more about the origins of our universe by studying the comet.

Rosetta: close orbits to lander deployment
Published on Oct 15, 2014

Animation showing Rosetta’s orbit in the lead up to, during and after lander separation.
The animation begins on 1 October 2014, when Rosetta is orbiting about 19 km from Comet 67P/Churyumov–Gerasimenko (all distances refer to the comet’s centre). The animation shows the transition to the close 10 km orbit by mid-October, and then the steps taken to move onto the pre-separation trajectory.
On the day of landing, 12 November, Rosetta makes a further manoeuvre 2–3 hours before separation to move to 22.5 km from the comet centre to deploy the lander, Philae. While Philae descends to the surface over a period of seven hours, Rosetta makes another manoeuvre to maintain visibility with the lander. A series of 'relay phase' manoeuvres then move Rosetta out to a distance of about 50 km, before moving first to a 30 km orbit and later to an orbit at about 20 km by early December.
The speed of the animation slows during the separation and lander phase to better highlight these events. The comet shape and rate of rotation is real – the comet rotates with a period of about 12.4 hours.

Landing on a Comet - The Rosetta Mission
October 23, 2014
Quote:
After a 10-year journey of some seven billion kilometres, the Rosetta mission is now heading towards its next major milestone – setting the lander Philae on a comet.
On 12 November 2014, a lander is scheduled to touch down on a comet for the first time in the history of spaceflight. “We don’t know exactly what awaits us there,” says lander Project Manager Stephan Ulamec from the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR).
Landing on Comet 67P/Churyumov-Gerasimenko will enable scientists to carry out experiments in situ for the first time. Comets are considered to be witnesses to the birth of the Solar System. Will the surface of the comet be in a primordial state? Do comets show evidence of prebiotic molecules and water, and did they therefore play a role in the origin of life on Earth? The Rosetta mission is expected to help answer such questions.

Scientists: Rosetta Comet Smells Terrible
Published on Nov 4, 2014
Quote:
The Rosetta comet mission landing is drawing closer, and with the landing of Europe's Philae robot on Comet 67P/Churyumov-Gerasimenko comes another scientific conclusion: the comet smells disgusting. The cloud around the icy comet contains a pungent chemical mix of hydrogen sulfide, ammonia, sulfur dioxide, methanol, carbon disulfide and formaldehyde, which amounts to a terrible, terrible odor. What is it exactly? And what other odors does space have in store? Kim Horcher, Tim Frisch, and Brandon Winfrey (Insomniac Games, Sunset TV Host) discuss!

Preparing for Comet Landing

After a ten-year journey, Rosetta and Philae had finally reached their destination, Comet 67P/Churyumov–Gerasimenko. Rosetta spent many weeks studying the comet, sending lots of information back to Earth. But where was Philae going to land? Eventually the scientists on Earth found the best place on the comet for Philae to land. Soon it was time to make the final preparations for Philae's great adventure. Both spacecraft couldn't wait any longer. The whole world would be watching as Rosetta and Philae prepared for their biggest challenge yet...

Rosetta's science
Published on Nov 6, 2014
Quote:
Rosetta is a science mission and it is using 21 onboard instruments (11 on the orbiter, 10 on the lander) to explore two key scientific questions: did water on Earth come from comets and did comets help kick start life on Earth?
Since Rosetta came out of hibernation in January, we now know comet 67P/Churyumov Gerasimenko’s mass (around 10 billion tonnes), shape (rubber duck) and rotation (every 12 hours and 24 minutes). Its cameras have shown gas and dust streaming away from the comet, locating areas of activity and imaging them for the first time. The orbiter has also captured dust grains and detected water and gases in the comet’s atmosphere or coma
