据英国《自然》杂志网站2月6日报道,美国国家航空航天局(NASA)马绍尔太空飞行中心的核研究主管迈克尔·霍茨希望宇航员能够乘坐核反应堆到达火星。他认为,少量的铀-235(其能量密度是液体燃料的100万倍)可以通过裂变产生热为火箭提供动力。
According to the British magazine Nature’s website February 6, Michael Hortz, director of nuclear research at the NASA Marshall Space Flight Center, hopes that astronauts can take the nuclear reactor to reach Mars. He believes that a small amount of uranium-235, whose energy density is one million times that of liquid fuels, can power rockets through fission heat generation.
