Evidence for carbynes in comets might come from remote-sensing analyses of the volatile species in the coma of active comets, in particular from the study of carbon-chain molecules abundances [88]. Using narrowband filter photometry, C3 and C2 were detected in amounts that are classified as being typical in comets Hale-Bopp and Halley [89] and as "being depleted in carbon-chain molecules in comet 67P/Churyumov-Gerasimenko, the new target of the ESA ROSETTA mission, and comet LINEAR 1999...

NASA s most recent comet missions are Deep Impact and Rosetta. Deep Impact was launched on January 12, 2005, with Comet Tempel 1 as its target. The spacecraft encountered Tempel 1 on July 3, 2005, at which time it released a 770-pound (350 kg) copper projectile at the comet. Cameras and spectrometers on the spacecraft photographed and collected samples of materials ejected from the comet nucleus and relayed that information to scientists on Earth. Rosetta was launched on March 2, 2004, with Comet 67P/Churyumov-Gerasimenko as its target. The spacecraft will orbit the comet and make observations for about two years as the comet approaches the Sun. It will also release a small package of instruments that make the first-ever landing on the surface of a comet.

For obtaining and studying the phase-angle dependence of linear polarization for comets, we used our own homogeneous data sets received with narrowband filters [31,34-40]. Only comet C/1982 Ml (Austin) was observed through the wideband V filter. These data were supplemented with data for comets C/1982 Ml (Austin), 67P/Churyumov-Gerasimenko [41], C/1989 XI (Austin) [42-45], C/1983 HI (IRAS-Araki-Alcock) [46], and IP/Halley [47]. All data for the blue and red domains of the continuum spectra are shown on the left and right panels in Fig. 1(a). Most measurements of polarization were made for the whole coma (several...

The Central On-Board Computer of the Philae Lander in the Context of the Rosetta Space Mission. Andras Baldzs, from the Wigner Research Centre for Physics in Budapest, Hungary, presented an overview of the major hardware and software design aspects of the central on-board computer of the Philae lander, which traveled over 10 years as the precious payload of the Rosetta spacecraft that recently made the historical encounter with the comet 67P/Churyumov-Gerasimenko.
