根据美国宇航局最新公布的一个设想,人类将有望在未来20年内将宇航员送上火星表面。这项新计划是由美国宇航局喷气推进实验室的科学家们提出来的,其核心计划是首先将宇航员送往火星的卫星火卫一,随后再从那里启程登陆火星。而其最终计划则是在2043年实现让人类宇航员在火星表面生活一年的目标。其关键点是,该计划将完全基于目前已经存在或已经处于开发阶段的技术来达成全部目标。这种充分利用现有基础的方案被视为是在不大幅增加现有航天预算的情况下,达成载人火星登陆
According to NASA’s latest announcement, mankind is expected to send astronauts to the surface of Mars within the next 20 years. The new plan was proposed by scientists at NASA’s Jet Propulsion Laboratory, whose core plan is to first send the astronauts to Mars on Mars and then land on Mars again. Its final plan is to achieve the goal of letting human astronauts live on Mars for one year by 2043. The key point is that the program will reach its full goal based solely on technologies that are currently in place or already under development. This program, which takes full advantage of the existing infrastructure, is seen as reaching a manned Mars landing without substantial increases in the existing space budget
