Back in 1969, it was the Apollo 11 crew who flew to the moon in a spaceship. When U. S. astronauts Neil Armstrong and Edwin “Buzz” Aldrin stepped foot on the moon, they were the first. Meanwhile, their fellow astronaut Michael Coilins circled the moon in their spaceship, named Columbia.
When Armstrong and Aldrin were done with their walk, they returned to the command module, and back to Earth. That part of the spaceship is on view at the Smithsonian's Air and Space Museum in Washington, D. C. But, if you cannot get to Washington, soon you will be able to see Columbia on your computer or your smartphone.
Digital scientists are scanning the inside of the spaceship. They are creating an online model, in three dimensions, or“3 D”. By looking at these photographs, you will be able to see outer space, the way the astronauts did. It will be like sitting in their seats.
Want your very own Columbia spaceship? You will be able to print a 3D copy of Columbia. Experts say anyone can make a life-sized model. But they expect most people to make smaller models of the 320×400 cm(11'X 13')command module.
Scientists are using special 3D technology to scan the inside. They use cameras on long arms to take the photographs. The thousands of photographs taken will be combined with 50 laser scans.
What would it be like to sit inside Columbia and take a look around? All the images will be loaded into software that allows you to look around the module on a computer screen. The user will be able to see the Columbia both inside and out. The Smithsonian says that the 3D technology gives the user ways to see things they cannot see at the museum. And it will give information that even the museum curators(馆长)have not seen before.
“With the Command Module, no one has been inside since it came into the collection, ” says Adam Metallo. Smithsonian 3D imaging specialist. “Now the information we capture can give anyone in the world a view of what it looks like inside this incredible piece of history. ”
China is showing the world its great resolve in the global climate campaign with concrete and self-motivated efforts as well as serious commitment.
At the opening ceremony of the Paris climate summit, Chinese President Xi Jinping restated China's plan made in June to cut its carbon emissions(排放)per unit of GDP by 60-65 percent from 2005 levels by 2030, and increase non-fossil fuel sources in primary energy consumption to about 20 percent.
With a large population, China is facing increasing resource limits, severe environmental pollution and a worsening ecosystem, and its citizens are also becoming increasingly aware of environmental problems. Suffering environmental problems and seeing the efforts as important to transforming its economic growth pattern, the country has much at risk if climate change is left unattended.
Actually, climate change efforts are already included in China's medium—and long-term program of economic and social development, and ecological efforts are the clear characteristics in China's 13th Five-Year Plan(2016-2020).
Although it is and will be a developing country for a long time to come, China has been actively involved in the global campaign against climate change, now topping the world in terms of energy conservation and use of new and renewable energies.
However, China's development rights need to be respected. It is unfair to overstress China's status as one of the world's largest greenhouse gas emitters and regard it as the major part of responsibilities in the global fight against climate change.
It is worthy of notice that China's emissions of greenhouse gases per person are far lower than those of developed countries, especially the United States, although rapid economic expansion and its population base have made it one of the biggest producers of the gases.
To show its great resolve, Beijing in September also announced the establishment of an independent South-South cooperation fund of 20 billion RMB to help developing countries affected by global warming.
While China is eagerly accomplishing its policy commitments, developed countries should stop questioning China's commitment to fighting climate change and pointing fingers, and start shouldering their due responsibilities instead.
As the saying goes, “No man is an island. ”We all need to connect with other people to fully give meaning to our lives. As we grow older, we develop closeness to certain people.
