Они сделали это! Минимальное расстояние пролета составило 3,2 км. ЕМНИП, это рекорд. Разрешение фото до 10 метров. Отн. скорость 10,73 км в сек. До Земли 7000000 км.

Chinese space probe flies by asteroid Toutatis

 BEIJING, Dec. 15 (Xinhua) -- China's space probe Chang'e-2 has successfully conducted a maneuver in which it flew by the asteroid Toutatis, about seven million km away from the Earth.
Travelling in deep space, Chang'e-2 made the flyby on Dec. 13 at 16:30:09 Beijing Time (08:30"09 GMT), the State Administration of Science, Technology and Industry for National Defense (SASTIND) announced on Saturday.
The flyby was the first time an unmanned spacecraft launched from Earth has taken such a close viewing of the asteroid, named after a Celtic god.
It also made China the fourth country after the United States, the European Union and Japan to be able to examine an asteroid by spacecraft.
Chang'e-2 came as close as 3.2 km from Toutatis and took pictures of the asteroid at a relative velocity of 10.73 km per second, the SASTIND said in a statement.
Sources with the administration told Xinhua that Chang'e-2 is continuing its deep space travel and will reach a distance of more than 10 million km away from Earth in January next year.
Chang'e-2 was launched on Oct. 1, 2010 from Xichang Satellite Launch Center and later orbited the moon to finish a more extensive probe than its predecessor Chang'e-1.
Chang'e-2 left its lunar orbit for an extended mission to the Earth-Sun L2 Lagrangian point on June 9, 2011, after finishing its lunar objectives, which collected data for a complete lunar map.
The probe departed from L2 this year and began its mission to Toutatis.
"The success of the extended missions also embodies that China now possesses spacecraft capable of interplanetary flight," said Wu Weiren, chief designer of China's lunar probe program.
Chang'e-2's extended missions, which were conducted millions of km away from Earth, have tested China's spacecraft tracking and control network, including two newly built measuring and control stations in the northwest Xinjiang Uygur Autonomous Region and northeast Heilongjiang province, according to the SASTIND.

More info: 20 Kbps at 7 million km, 90% data has been received so far.

Asteroid Toutatis Slowly Tumbles by Earth



December 14, 2012
 Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have generated a series of radar data images of a three-mile-long (4.8-kilometer) asteroid that made its closest approach to Earth on Dec. 12, 2012. The radar data images of asteroid Toutatis have been assembled into a short movie, available online at: http://www.jpl.nasa.gov/video/index.php?id=1175 .

 The images that make up the movie clip were generated with data taken on Dec. 12 and 13, 2012. On Dec. 12, the day of its closest approach to Earth, Toutatis was about 18 lunar distances, 4.3 million miles (6.9 million kilometers) from Earth. On Dec. 13, the asteroid was about 4.4 million miles (7 million kilometers), or about 18.2 lunar distances.

 The radar data images of asteroid Toutatis indicate that it is an elongated, irregularly shaped object with ridges and perhaps craters. Along with shape detail, scientists are also seeing some interesting bright glints that could be surface boulders. Toutatis has a very slow, tumbling rotational state. The asteroid rotates about its long axis every 5.4 days and precesses (changes the orientation of its rotational axis) like a wobbling, badly thrown football, every 7.4 days.

 The orbit of Toutatis is well understood. The next time Toutatis will approach at least this close to Earth is in November of 2069, when the asteroid will safely fly by at about 7.7 lunar distances, or 1.8 million miles (3 million kilometers). An analysis indicates there is zero possibility of an Earth impact over the entire interval over which its motion can be accurately computed, which is about the next four centuries.

 This radar data imagery will help scientists improve their understanding of the asteroid's spin state, which will also help them understand its interior.

 The resolution in the image frames is 12 feet (3.75 meters) per pixel.

 NASA detects, tracks and characterizes asteroids and comets passing close to Earth using both ground- and space-based telescopes. The Near-Earth Object Observations Program, commonly called "Spaceguard," discovers these objects, characterizes a subset of them, and plots their orbits to determine if any could be potentially hazardous to our planet.

 JPL manages the Near-Earth Object Program Office for NASA's Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology in Pasadena.

Surface Features of Asteroid Toutatis Revealed by Radar

With optical telescopes, it's difficult to make out the surface features of asteroid Toutatis. Radar gives us a different picture. On Dec. 12 and 13, 2012, scientists pointed NASA's Goldstone Solar System Radar precisely on the asteroid while it was over four million miles/6.9 million kilometers away. Using the bounced radar signals scientists assembled these "images" showing the surface features of Toutatis, an asteroid measuring about 3 miles long (4.8 km). The orbit of Toutatis is well understood. An analysis indicates there is zero possibility of an Earth impact over the entire interval over which its motion can be accurately computed, which is about the next four centuries.

Во дают китайцы!

Не то слово... На базе не самой новой ГСО-платформы, пусть и допиленной.

А еще каких-то 15 лет назад все ухахатывались над анекдотами про двести кочегаров и т.п.

Молодцы китайцы! Тут я им по-настоящему завидую.

это ещё раз говорит о преимуществе развитого социализма над загнивающем капитализмом.  равно как и запуск первого спутника в КНДР :!:

А теперь он развернется и возьмет курс на Европу, спутник Юпитера...
