到达火星需要多长时间?简单解释

by Tobias

问一些业余天文学家,到达火星需要多长时间?旅途需要一些时间,并伴随着一系列特点

到达火星需要多长时间。

人类早就有殖民火星的想法。在遥远的未来,地球可能不再适合人类居住。因此,前往太阳系中的其他行星并在那里建立生命基地是合情合理的。火星尤其适合,但到达火星需要更长的时间。

  • 单程前往火星大约需要九个月。回程也需要同样的时间。航天器总共要运行 18 个月左右。
  • 火星勘测轨道飞行器在七个月内完成了这次飞行。然而,与持续时间更长的太空飞行相比,这次飞行所需的能量要大得多。
  • 以前没有人踏上过火星。迄今为止,只有空间探测器和所谓的漫游者探索过火星。
  • 我们正在努力将人类送上火星。但首先它需要再次登陆月球,这样它才能被用作通往火星的 “垫脚石”。
  • 埃隆-马斯克(Elon Musk)也将目光投向了将人类带向火星。这就是他在 2002 年创立 SpaceX 公司的原因。

太空旅行对人类的影响

人类不是为太空旅行而设计的,这已成为不成文的规定。长时间处于失重状态对健康不利。飞往火星至少需要在太空中停留 400 至 450 天。基于这些原因,长时间停留在太空对人类是不健康的:

  • 宇航员的心理会受到严重伤害。他或她将被长期 “困 “在一个小飞船里,只能与少数几个与他们一起飞行的人接触
  • 从身体角度看,可能会出现健康问题。例如,在太空停留时间较长时,由于失重,骨质会减少。
  • 除此之外,太空飞行期间还会产生太空辐射,人体暴露在辐射之下。这会严重破坏人体细胞中的遗传物质。
