| EPOXI Comet Hartley 2 Flyby Video (2010.11.04) |

This video clip was compiled from images taken by NASA's EPOXI mission spacecraft during its flyby of comet Hartley 2 on Nov. 4, 2010. During the encounter, the spacecraft and comet whisked past each other at a speed of 12.3 kilometers per second (27560 miles per hour). The spacecraft came within about 700 kilometers (435 miles) of the comet's nucleus at the time of closest approach. "While future generations should have the opportunity to truly explore comets, this flyby gives us an excellent preview of what they will get to enjoy," said EPOXI principal investigator Michael A'Hearn of the University of Maryland, College Park. "Hartley 2 exceeded all our expectations in not only scientific value but in its stark majestic beauty." The video clip of the flyby is comprised of 40 frames taken from the spacecraft's Medium-Resolution Instrument during the encounter. The first image was taken at about 37 minutes before the time of closest approach at a distance of about 27350 kilometers (17000 miles). The last image was taken 30 minutes after closest approach at a distance of 22200 kilometers (13800 miles). The spacecraft was able to image nearly 50 percent of the comet's illuminated surface in detail. The EPOXI mission's flyby of comet Hartley 2 was only the fifth time in history that a comet nucleus has been imaged, and the first time in history that two comets have been imaged with the same instruments and same spatial resolution. credit: NASA/University of Maryland source ...

| Mars Express - Phobos Flyby By Visualization (2010.03.07) |

Mars Express encountered Phobos on 7 March 2010, smoothly skimming past at just 67 km, the closest any manmade object has ever approached Mars enigmatic moon. The data collected could help unlock the origin of not just Phobos but other second generation moons. Something is not right about Phobos. It looks like a solid object but previous flybys have shown that it is not dense enough to be solid all the way through. Instead, it must be 25-35% porous. This has led planetary scientists to believe that it is little more than a rubble pile circling Mars. Such a rubble pile would be composed of blocks both large and small resting together, with possibly large spaces between them where they do not fit easily together. credits: ESA/DLR/FU Berlin (G.

Karolina Gočeva (in Macedonian: Каролина Гочева, born April 28, 1980) in Bitola is currently the leading Macedonian female singer. She got her first big break at the age of 11 when she performed at the children's festival "Si-do" in Bitola and annual festival "Makfest 1991" in Štip with the song "Mamo, pušti me" ("Mum, let me go"). Her career was just starting, so she used the national festivals to promote her voice and talent. She became a regular participant in SkopjeFest, debuting in 1994 when she performed the song "Koj da ti kaže" ("Who to tell you"). In the following years she participated successfully, especially when SkopjeFest was used to choose a song for Eurovision. In 1996, Karolina participated with "Ma, ajde kaži mi" ("Come on, tell me") and reached 9th place. In 1998, she participated with "Ukradeni noќi" ("Stolen nights") and was more successful, reaching 4th place with 10454 televotes. In 2000, Karolina joined the record label, Avalon Productions, who helped her release her debut album "Jas imam pesna" (I've got a song). From that album, Karolina released many singles including "Sakaj me" ("Love me"), "Bez ogled na se"("No matter what") and "Nemir" ("Restless"), the latter of which she sang in a duet with Tose Proeski. With her first album released, Karolina took part at the SkopjeFest Eurovision song selection. Karolina nearly missed out coming in 2nd with song "Za nas" ("For us") from Darko Dimitrov, which managed to receive 916 points.
