Imperadores, e outros déspostas, sempre agiram da mesma maneira: é preciso escavar um canal? Expulsem os camponeses do traçado. Vamos abrir avenidas? Derrubem esses hutongs (cortiços). Espaços para escritórios e empresas multinacionais: passem os tratores nesses três quarteirões.
Enfim, quando não há problemas em deslocar algumas milhares de pessoas, tudo avança...

9,000 people to make way for huge radio telescope

MORE than 9,000 people in southwest China’s
Guizhou Province will be relocated before the completion of the world’s
largest radio telescope in September, local authorities said yesterday.
Development of the Five-hundred-meter Aperture Spherical Radio
Telescope (FAST), which sits between hills in the rural region, began in
March 2011 with an investment of 1.2 billion yuan (US$184.3 million).
On completion, the telescope will be the world’s largest of its kind,
overtaking Puerto Rico’s Arecibo Observatory, which is just 300 meters
in diameter.
The relocation program was proposed last year at the Guizhou
Provincial Committee of the Chinese People’s Political Consultative
Conference, according to its secretary-general Li Yuecheng.
Anyone living within 5 kilometers of the telescope will be relocated
to create “a sound electromagnetic wave environment,” Li said.
The move will affect 9,110 residents, he said. Each person will
receive compensation of 12,000 yuan, with some ethnic minority families
getting an additional 10,000 yuan in housing support, the official said.
Wu Xiangping, director-general of the Chinese Astronomical Society,
said earlier that the telescope’s high level of sensitivity “will help
us to search for intelligent life outside of the galaxy.”
Meanwhile, Chinese scientists said they have developed a system to
measure the leak rate for a vacuum environment to be used in the
country’s three-step lunar exploration program.
According to researchers at the Lanzhou Institute of Physics under
the China Academy of Space Technology, the system will help scientists
figure out a better way to preserve samples from the moon.
“The third step of the lunar exploration project involves taking
samples from the surface of the moon back to Earth,” said Li Detian, the
chief scientist on the research team.
“The samples will be packed in a vacuum environment. The accuracy of
measuring the finest leak in a vacuum capsule will have direct impact on
the research result of the samples.”
Cheng Yongjun, a member of the team, said the measurement system will
ensure a similar vacuum environment as found on the moon for the
samples.
It will also make sure that the 2 kilogram samples remain
uncontaminated on their way back to Earth, and prevent them from being
affected by any kind of environment change, including extremely high and
low temperatures.
China has a three-step moon exploration project: orbiting, landing
and return. The Chang’e-5 lunar probe is scheduled to be launched in
2017, which will fulfill the final stage of the project.
