东京奥运会开幕式将上演人造流星雨

分类:体育英语   更新:2016/8/13   来源:本站原创

    A Japanese research company called ALE Co. (aka Star-ALE) is bidding to put on a sensational1 pyrotechnics display for the opening ceremony of the 2020 Summer Olympics in Tokyo. But this is no regular fireworks show: ALE Co.'s 'Sky Canvas' is an artificially created meteor shower - uh-huh - which would see hundreds of tiny, coloured fireballs rain down over the host city.

    一家叫做ALE CO的日本公司正在筹划在2020东京夏季奥运会开幕式上进行一场举世无双的烟火表演:他们的“天空画布”项目将上演一场人造流星雨,届时将有数百颗彩色火球从天而降。

    According to a report at industrial design site Core 77, if ALE Co. has its way, this amazing concept would result in the human-made shooting stars being visible from well outside of Tokyo too, with the next-level pyrotechnics expected to be viewable from up to 100 kilometres away from the city.

    But how does it all work? ALE CO. says it can "artificially recreate" the process of natural shooting stars by sending up a satellite into orbit carrying a payload of between 500 to 1,000 specialised pellets called "source particles".

    Once the particles – composed of chemicals designed to emit flames in various colours - are discharged from the satellite, they'd travel around Earth until they enter the atmosphere and begin to burn up. With numerous particles being discharged at the same time, the company says it can create a safe, on-demand meteor shower for the wonderment of the crowds below.

    But wonderment comes at a cost, and in this case, that cost isn't cheap. Core77 reports that each combustible2 pellet comes in at about US$8,100 to produce, and that's not including the costs involved in actually launching the Sky Canvas satellite. Ouch.

    The company has tested its source particles in the lab, using a vacuum chamber3 and hot gases to simulate the conditions t
