When NASA first started sending up astronauts, they quickly discovered that ballpoint pens would not work in zero gravity. To combat the problem, NASA scientists spent a decade and $12 billion to develop a pen that writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to 300°C.
在美国太空总署第一次派太空人上太空时,他们很快发现圆珠笔无法在零重力的情况下工作。为了解决这个问题,美国太空总署花了10年时间和120亿美元研发了一种可以在零重力,倒置,水下,和几乎一切表面包括玻璃上书写,适应温度的范围从0摄氏度到300摄氏度的钢笔。
