The difference between the amount of energy the Earth receives from the sun and the energy it radiates back to space affects whether our planet's climate warms or cools. For now, nobody can measure that temperature difference precisely, but scientists at Johns Hopkins University’s Applied Physics Laboratory, in Maryland, plan to change that, using an array of small, inexpensive satellites called ‘cubesats.’ VOA’s George Putic has more.
地球从太阳上接收能量的数量与地球向太空中反射能量数量之间存在差异,这一差异可以反映地球气候冷暖如何 。如今,没人能够精测测量这一温差,但是,在坐落于马里兰的美国约翰霍普金斯大学应用物理实验室中,科学家们计划改变这一状况,方法就是使用一些小型、价格不贵的卫星,他们称其为“cubesats”本台记者乔治·卜迪科为我们带来更多报道 。
