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. |
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.
Since its blast-off, Chang'e 2 has scored several
records: being the first to capture full coverage map of the moon with a
resolution of seven meters; being the first object ever to reach the L2 point
directly from lunar orbit; and being the first to closely observe the asteroid
Toutatis.
China early this year published a full coverage map of
the moon, as well as several high-resolution images of the celestial body,
captured by Chang'e-2. The resolution of the images is 17 times greater than
those taken by Chang'e-1.
"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.
However, China still belongs to the second tier in lunar
probe internationally, said Ouyang Ziyuan, chief scientist for China's lunar
orbiter project, adding that the Unites States and Russia are still leading
nations in this field.
Wu Weiren stressed international cooperation in lunar
probe, saying it is a shared responsibility of world scientists to work
together in lunar and deep space exploration for the common good of the human
race.

Comentário: Pois é leitor, a China torna-se assim a
quarta nação do mundo (EUA, Rússia, Japão) a se aventurar com uma espaçonave em
espaço profundo (após a órbita lunar) e a Agência Espacial Chinesa (CNSA) passa
a ser a quinta a realizar esse feito, já que a NASA, ROSCOSMOS, ESA, e JAXA são
as outras que já cumpriram missões ou estão cumprindo nessa região profunda do
espaço. Vale dizer que como a Agência Espacial Europeia (ESA) é composta por
diversos países europeus e nenhum deles realizou um feito com esse sozinho,
somente os EUA, a Rússia, o Japão e agora a China são detentores desse recorde,
mas estando a Índia bem próxima também de alcançar esse feito, pois já chegou recentemente
em órbita lunar. Vale lembrar que o Brasil em parceria com a Rússia está
tentando entrar nesse fechadíssimo clube com a iniciativa de 13 instituições universitárias
e de pesquisas no desenvolvimento de uma pequena sonda visando envia-la para um
asteroide em 2015, ou seja, a já conhecida “MISSÃO ASTER”, mas que dependerá do
governo DILMA para que possa sair do papel. O leitor diria: “Duda, vá com calma, você esta sonhando muito alto”, mas na verdade não seria exatamente uma questão de sonho e sim de completo delírio.
Ótimo receber notícias sobre o SpaceMeta, e espero que possam nos mais aprofundar a respeito do seu projeto para o GLXP. Relativamente ao feito dos chineses, sabemos que em breve seremos nós, e em 2017 tiraremos a prova dos 9 (e creio que este projeto não se pode atrazar, porque tudo depende também dos calculos de envio, logo creio que seja mister se cumprir as datas neste caso).
ResponderExcluirCaro Israel!
ResponderExcluirComo o novo PNAE é um documento fantasma, desconhecido por todos, não temos nem condições de saber se a "Missão ASTER" foi ou não foi incluída no documento, e assim sua realização ainda é incerta.
