    UFO Rosetta probe & Philae lander approach comet

    Cool space stuff!

    Rosettas lander Philae will target Site J, an intriguing region on Comet 67P/ChuryumovGerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites.

    Site J is on the head of the comet, an irregular shaped world that is just over 4 km across at its widest point. The decision to select Site J as the primary site was unanimous. The backup, Site C, is located on the body of the comet.

    The 100 kg lander is planned to reach the surface on 11 November, where it will perform indepth measurements to characterise the nucleus in situ, in a totally unprecedented way.

    But choosing a suitable landing site has not been an easy task.

    As we have seen from recent close-up images, the comet is a beautiful but dramatic world it is scientifically exciting, but its shape makes it operationally challenging, says Stephan Ulamec, Philae Lander Manager at the DLR German Aerospace Center.

    None of the candidate landing sites met all of the operational criteria at the 100% level, but Site J is clearly the best solution.

    Rosetta's Lander Philae Snaps Mind-Blowing Comet Selfie : Discovery News

    dnews files 2014 09 comet selfie 670x440 140910 jpg - Rosetta probe & Philae lander approach comet

    Youd be hard-pressed to find a more impressive selfie than this!

    Attached to the European Space Agency's comet-chasing spacecraft Rosetta, the Philae lander opened one of its robotic eyes when the mission was orbiting comet 67P/ChuryumovGerasimenko at a distance of only 50 kilometers (31 miles) on Sunday. With two high-contrast exposures, the lander captured one of Rosettas solar panels in the foreground with the comet behind.

    Philae is currently going through a series of preparations ahead of its historic landing on the comets nucleus, the first time such a feat has ever been attempted. The camera used in this selfie, called the Comet Infrared and Visible Analyser (CIVA), is one of ten instruments the lander will use to study the comets surface up-close.

    Part of this instrument, called CIVA-P, will compile a 360 degree panoramic image of the probes landing site, returning a truly alien view to scientists back on Earth.

    BBC News - Rosetta takes 'selfie' ahead of landing site selection

     77527285 comet on 5 september 2014 - Rosetta probe & Philae lander approach comet

    The Rosetta spacecraft has sent a hauntingly beautiful picture of itself from deep space.

    It was taken with the CIVA camera situated on Rosetta's landing craft known as Philae.

    The image was taken on 7 September from a distance of about 50km from the comet seen at the top of the picture.

    It shows the edge of the spacecraft and one of its 14m-long solar wings glistening in sunlight against the blackness of space.

    Faint details of the spacecraft's protective blanket, the ridges of one of the solar wing's supports can be seen clearly as can the wiring and hinges on the wing itself.

    At the top of the picture is Comet 67P also known as Churyumov-Gerasimenko with each of its distinct lobes visible.

    Five possible landing sites were chosen last month. They were selected because they appeared to be relatively flat and smooth. But as the spacecraft has neared the comet, its rocky jagged surface which can be clearly seen in this picture has come sharply into focus.

    UFO Rosetta probe to deploy Philae lander on Nov 12th

    Rosetta to deploy lander on 12 November / Rosetta / Space Science / Our Activities / ESA

    The European Space Agencys Rosetta mission will deploy its lander, Philae, to the surface of Comet 67P/ChuryumovGerasimenko on 12 November.

    Philaes landing site, currently known as Site J, is located on the smaller of the comets two lobes, with a backup site on the larger lobe. The sites were selected just six weeks after Rosetta arrived at the comet on 6 August, following its 10-year journey through the Solar System

    In that time, the Rosetta mission has been conducting an unprecedented scientific analysis of the comet, a remnant of the Solar Systems 4.6 billion-year history. The latest results from Rosetta will be presented on the occasion of the landing, during dedicated press briefings.

    The main focus to date has been to survey 67P/ChuryumovGerasimenko in order to prepare for the first ever attempt to soft-land on a comet.

    UFO Philae landing site

    ESA confirms the primary landing site for Rosetta / Rosetta / Space Science / Our Activities / ESA

    Philae s primary landing site mosaic large - Rosetta probe & Philae lander approach comet

    ESA has given the green light for its Rosetta mission to deliver its lander, Philae, to the primary site on 67P/ChuryumovGerasimenko on 12 November, in the first-ever attempt at a soft touchdown on a comet.

    Philaes landing site, currently known as Site J and located on the smaller of the comets two lobes, was confirmed on 14 October following a comprehensive readiness review.

    Since the arrival, the mission has been conducting an unprecedented survey and scientific analysis of the comet, a remnant of the early phases of the Solar Systems 4.6 billion-year history.

    Rosetta and Philae separation confirmed / Rosetta / Space Science / Our Activities / ESA

    Separation large - Rosetta probe & Philae lander approach comet

    The Philae lander has separated from the Rosetta orbiter, and is now on its way to becoming the first spacecraft to touch down on a comet.

    Separation was confirmed at ESAs Space Operation Centre, ESOC, in Darmstadt, Germany at 09:03 GMT / 10:03 CET. It takes the radio signals from the transmitter on Rosetta 28 minutes and 20 seconds to reach Earth, so separation actually occurred in space at 08:35 GMT / 09:35 CET.

    The first signal from Philae is expected in around two hours, when the lander establishes a communication link with Rosetta. Philae cannot send its data to Earth directly it must do it via Rosetta.

    Should find out about the landing by about 4pm GMT.

    It's like they did the world's greatest trick shot.

    That's incredibly clever stuff IMO.

    ... and it would have been great for the late Colin Pillinger to have seen this happen.
