The ESA’s 10 year mission of the Rosetta satellite to rendezvous with Comet 67P and to launch Philae the Comet Lander which has landed and will commence a one year full studies of this comet with pics from the lander and satellite and data of a variety of on-board instruments.
Comet 67P/Churyumov–Gerasimenko is a very interesting comet just from its shape alone.
The first image is from Philae as it was launched from Rosetta. The bubbles are sun-flare – glare on the RAW image with the Sun and its rays on the center bottom of the raw image.
These 11 experiments will run for about 64 hours before exhausting batteries. Afterwards, every other day after battery recharge, they will run for about 1 hr. [since the landing bounced, the lander is not in an optimal location/position to optimally charge so the original estimates may now differ.]
This is a tremendous engineering and science acheivement of the ESA to be the first to land upon a comet. The rendezvouse began on 6-August-2014 and for the last three months mapped the comet’s contours and emissions looking for an interesting and viable landing spot. 11:06 ET has the landed and is communicatinging – images to come.
Poland is also a part of ESA now. On the Philae Lander is one instrumentation that was built in Poland. More details are here .
More than 70 scientific instruments that were built in Poland, has[sic] already been sent to space. The instruments built at the Space Research Center of the Polish Academy of Sciences have studied Titan’s surface, have been on board ESA’s Venus and Mars Express missions, and are now studying the comet 67P/Churyumov–Gerasimenko.
