美国太空总署(NASA)现正研究利用磁力浮动的技术,制造下一代到太空的交通工具,可以大大减低飞行太空的成本,也许到那时,很多人都可负担得起到太空的平价观光费用。科学家认为,推动太空船到太空,环绕地球运行,最昂贵的部分是将太空船推动到高空,离开地球的地心吸力。科学家计划 NASA is studying ways to use magnetic floating technology to make the next generation of vehicles for space that can greatly reduce the cost of spaceflight, and perhaps by that time, affordable space for many people. cost. Scientists believe that to promote the spacecraft to orbit around the earth, the most expensive part is to push the spacecraft to high altitude, leaving the earth’s geocentric suction.
