از همه ی شما تقاضا دارم که نظرات خودتونو در مورد این وبلاگ اعلام کنید نقاط ضعف و قوط اون رو هم بگین.
توی یه وبلاگ دیگه دیدم که نویسنده از مخاطباش خواسته بود که در مورد شخصیتش حدس بزنن .
حالا اگه شما هم حوصلتون گذاشت ۴ خط بنویسین البته نه در مورد خودتون بلکه در مورد من (که نمیشناسین) ضمنا اگه فردی بتونه مشخصات من رو کامل بگه ....
شاید یه هدیه ناقابل پیش ما داره
.
آسمان دلتون بدون ابر همیشه شاد و سربلند باشید.

This dramatic image of Io was taken by the Long Range Reconnaissance Imager (LORRI) on New Horizons at 11:04 Universal Time on February 28, 2007, just about 5 hours after the spacecraft's closest approach to Jupiter. This processed image provides the best view yet of the enormous 290-kilometer (180-mile) high plume from the volcano Tvashtar, in the 11 o'clock direction near Io's north pole.
This is the last of a handful of LORRI images that New Horizons is sending "home" during its busy close encounter with Jupiter - hundreds of images and other data are being taken and stored onboard. The rest of the images will be returned to Earth over the coming weeks and months as the spacecraft speeds along to Pluto. + Read more

The Moon is the central figure in two different kinds of eclipses within one week. Here’s how. A total lunar eclipse, partly visible from every continent around the world, will occur on March 3 when the Moon will pass into and out of the shadow of Earth. The Moon will appear to glow with a distinct reddish cast. The entire event will be visible from Europe, Africa and western Asia. In eastern Asia, Moonset occurs during various stages of the eclipse. For example, the Moon sets while in total eclipse from central China and southeast Asia. Western Australia catches part of the initial partial phases but the Moon sets before totality. Observers in eastern North and South America will find the Moon already partially or totality eclipsed at Moonrise. From western North America, only the final phases are visible. ![]() Image above: Total Lunar Eclipse: 2004. Credit: Fred Espenak. Here in the United States, you have to be in the eastern half of the country to see the total eclipse. At the end of the day on Saturday, go outside and face east. As the sun sets in the western skies, a red Moon will rise before your eyes--fantastic! Maximum eclipse is at 6:21 p.m. EST. The next total lunar eclipse will occur on August 28 this summer. ![]() Video right: STEREO spacecraft captures a lunar transit of the sun. Click on image to view video. Credit: NASA. + STEREO high resolution images On Feb. 25, 2007 there was another kind of eclipse of the Moon when it crossed the face of the Sun - but it could not be seen from Earth. This sight was visible only from the STEREO-B spacecraft in its orbit about the sun, trailing behind the Earth. NASA's STEREO mission consists of two spacecraft launched in October, 2006 to study solar storms. The transit started at 1:56 am EST and continued for 12 hours until 1:57 pm EST. STEREO-B is currently about one million miles from the Earth, 4.4 times farther away from the Moon than we are on Earth. As a result, the Moon will appear 4.4 times smaller than what we are used to. This is still, however, much larger than, say, the planet Venus appeared when in transited the Sun as seen from Earth in 2004. This alignment of STEREO-B and the Moon was not just due to luck. It was arranged with a small tweak to STEREO-B's orbit last December. The transit is quite useful to STEREO scientists for measuring the focus and the amount of scattered light in the STEREO imagers and for determining the pointing of the STEREO coronagraphs. The Sun as it appears in these the images and each frame of the movie is a composite of nearly simultaneous images in four different wavelengths of extreme ultraviolet light that were separated into color channels and then recombined with some level of transparency for each. + Click here for additional eclipse details | |

Aboard the International Space Station, the Expedition 14 crew members continued their work this week with scientific experiments, station maintenance and additional clean up following the Feb. 22 Russian spacewalk.
Friday, the three crew members participated in an experiment that tests hand-eye coordination before, during and after the mission to better understand how the brain adapts during spaceflight. The experiment will be performed again with Expedition 15.
A planned altitude reboost for the space station on Friday was cancelled and rescheduled for later this month. With the launch of the STS-117 shuttle mission delayed until no earlier than late April, Russian flight controllers now plan on two separate reboosts for the station.
The first reboost, now planned for around March 16, will position the station for the launch of the Expedition 15 crew and U.S. businessman Charles Simonyi on the Soyuz TMA-10 craft from the Baikonur Cosmodrome on April 7.
A second reboost on March 28 improves rendezvous opportunities for Atlantis’ flight and brings the station into the correct trajectory for the returning Soyuz craft to land in Kazakhstan on April 19 with Expedition 14 Commander Mike Lopez-Alegria, Flight Engineer Mikhail Tyurin and Simonyi.
Flight Engineer Suni Williams participated in robotics proficiency training with a computer-based simulation Wednesday. This training program maintains the crew's skill level in using Canadarm2 without actually moving the robotic arm.
On Tuesday, the International Space Station Independent Safety Task Force issued its final report. It was released simultaneously to Congress, NASA and the public.

Why Explore Space?
Completing the International Space Station, explains NASA Administrator Mike Griffin, is an integral part of the Vision for Space Exploration.
"Today," Griffin writes, "NASA is moving forward with a new focus for the manned space program: to go out beyond Earth orbit for purposes of human exploration and scientific discovery. And the International Space Station is now a stepping stone on the way, rather than being the end of the line."

| NASA's Cassini spacecraft has captured never-before-seen views of Saturn from perspectives high above and below the planet's rings. Over the last several months, the spacecraft has climbed to higher and higher inclinations, providing its cameras with glimpses of the planet and rings that have scientists gushing. "Finally, here are the views that we've waited years for," said Dr. Carolyn Porco, Cassini imaging team leader at the Space Science Institute in Boulder, Colo. "Sailing high above Saturn and seeing the rings spread out beneath us like a giant, copper medallion is like exploring an alien world we've never seen before. It just doesn't look like the same place. It's so utterly breath-taking, it almost gives you vertigo." Image right: Taking in Saturn's rings in their entirety was the focus of this particular imaging sequence. Image credit: NASA/JPL/Space Science Institute + Full image and caption + More images The images taken over last two months are being released today and include black and white and color mosaics, as well as a dramatic movie sequence showing the rings as they appeared to Cassini while it sped from south to north, rapidly crossing the ring plane. Also released is a playful view of the rings from high above, with the planet removed. Cassini's highly inclined orbits around Saturn will be progressively lowered so that, by late June-- three years after entering orbit -- the spacecraft will once more be orbiting in the ring plane. The new images and movie are available at: http://www.nasa.gov/cassini , http://saturn.jpl.nasa.gov and http://ciclops.org . The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
