Join the largest annual public space event on Earth!
World Space Week (WSW) is an annual observance held from October 4 to October 10 established by the United Nations General Assembly to be an international celebration of science and technology and their contribution to the betterment of the human condition.
Every year, the World Space Week Association, in coordination with the United Nations Office of Outer Space Affairs, selects a theme that participants are asked to incorporate into their World Space Week events. The theme for World Space Week 2012 is “Space for Human Safety and Security.” All World Space Week participants are requested to: 1) Plan World Space Week programs that address this theme in some way; 2) Incorporate this theme into all of their World Space Week publicity materials.
Various WSW events will be hosted by local participating organizations. In the Philippines, there are 11 registered events for WSW 2012. Everyone is invited to attend these events.
To infinity and beyond! 😀
Google and Youtube are celebrating 50th Anniversary of Space flight! 😀
The Google Doodle’s art wizards have created a distinctly 1960s-looking version of the famous logo. 🙂
The first letter ‘o’ has been replaced with a drawing of Gagarin in his space suit while the second ‘o’ has become the planet Earth.
Charmingly, when you first see the logo, an animated spaceship launches from the planet’s surface. If you want to see it take off again, just hit refresh.
The Gagarin Google Doodle is the latest in a long line of artistic logo variations that the search engine has produced.
Yuri Gagarin: 50th Anniversary of First Human Spaceflight
Gagarin made history when his Vostok 1 spacecraft took off from the Baikonur Cosmodrome in Kazakhstan and completed a 108-minute orbit of the Earth on Tuesday April 12, 1961.
Unsurprisingly, he became a national hero and was awarded the Hero of the Soviet Union.
Gagarin’s flight spurred the international space race between the United States and the Soviet Union, leading President John F. Kennedy to set the goal of being the first to land on the moon.
Seven years after Gagarin’s first journey into space, he was killed on a routine training flight. His pioneering legacy is remembered at Star City, Moscow’s oldest space-flight training facility.
“What beauty. I saw clouds and their light shadows on the distant dear earth…. The water looked like darkish, slightly gleaming spots…. When I watched the horizon, I saw the abrupt, contrasting transition from the earth’s light-colored surface to the absolutely black sky. I enjoyed the rich color spectrum of the earth. It is surrounded by a light blue aureole that gradually darkens, becoming turquiose, dark blue, violet, and finally coal black.”
— Yuri Alekseyevich Gagarin, Soviet pilot and cosmonaut

NASA’s Solar Dynamics Observatory (SDO) satellite captured the dark moon creating a partial eclipse of the Sun last March 2-4, 2011.
More still images here.
Watch HD Video.
These images, while unusual and cool to see, also have practical value to the SDO science team. Karel Schrijver of Lockheed-Martin’s Solar and Astrophysics Lab explains: “The very sharp edge of the lunar limb allows us to measure the in-orbit characteristics of the telescope e.g., light diffraction on optics and filter support grids. Once these are characterized, we can use that information to correct our data for instrumental effects and sharpen up the images to even more detail.”
On October 7, 2010, SDO observed its first lunar transit when the new Moon passed directly between the spacecraft (in its geosynchronous orbit) and the Sun.
The planned Valentine’s Day (Feb. 14, 2011) rendezvous between NASA’s Stardust-NExT mission and comet Tempel 1 inspired this chocolate-themed artist’s concept.

Just a few hours ago, NASA’s EPOXI mission spacecraft successfully flew past comet Hartley 2 at 6:59:47 a.m PDT (13:59:47 Universal Time) Thursday, Nov. 4.
The Deep Impact probe zoomed to within 435 miles (700 kilometers) of Hartley and it took incredible images of the comet’s solid nucleus. The close encounter marked just the fifth time that a spacecraft has ever visited a comet.
Experts say initial images from the flyby provide new information about the comet’s volume and material spewing from its surface. The small but active comet is full of surprises, with spinning jets, geysers of cyanide gas, and a strange, irregularly-shaped core. The nucleus is only about 2.2 km (1.4 miles) across, so there’s not much mass in it, which means that it has weak gravity. In fact, the round ends of the nucleus are bumpy and rough, indicating material is loosely aggregated there.
EPOXI is an extended mission that uses the already in-flight Deep Impact spacecraft. Its encounter phase with Hartley 2 began at 1 p.m. PDT (4 p.m. EDT) on Nov. 3, when the spacecraft began to point its two imagers at the comet’s nucleus. Imaging of the nucleus began one hour later.
I watched the coverage of this event through an online live steaming available at NASA TV. I was updating my Facebook and Twitter account as I was waiting for updates and images of the closest approach. After more than an hour since the webcast began, the first images that were taken many hours before close encounter were received. They depicted the comet nucleus as little more than a point of light, with the fuzzy coma surrounding it. I was saving screenshots every now and then as the images came in.
Moments later, a few of the close-approach images were finally shown. I was really amazed upon seeing its odd peanut-shaped body with an irregular and contoured surface. Images are available here and here. According to NASA EPOXI’s tweet, the 55 images taken about every 15 minutes were 256 x 256 subframes and the 5 close approach are full frames 1024 x 1024.
Those bright streamers of light are jets of gas shooting away from the comet, formed when frozen material on the comet surface gets heated by the Sun, expands, and shoots away.
These are medium-resolution; hi-res ones will be coming soon.
Scientists are interested in comets because they’re icy leftovers from the formation of the solar system about 4.5 billion years ago. Studying them could provide clues to how Earth and the planets formed and evolved.
Congratulations to the EPOXI team for a successful commetary encounter and for sending amazing images! 😀
