宏大構想：我們要去火星嗎？的劇情簡介 · · · · · ·
The attempt to send and land astronauts on Mars risks billions of dollars and the lives of those brave enough to attempt it. Is the possible benefit really worth the risk? And is it really achievable?
Guiding us through this ethical and scientific minefield is Dr Kevin Fong. Kevin\'s diverse background in astrophysics, aeronautics and medicine makes him uniquely placed to understand the technical and human challenges of this perilous journey. With the help of the BBC\'s rich archive and a cast of supporting experts, Kevin leads us through the journey to Mars stage by stage.
For Kevin, not only is this the toughest journey we will ever attempt, it is one that he feels we ultimately must make if we are to survive as a species.
2019年是尼爾·阿姆斯特朗登陸月球50周年。這是太空競賽的巔峰，也是整個20世紀最偉大的科技成就，但是我們是否應該派宇航員前往火星呢？美國國家航空航天局在1969年成功登陸月球之後，最大的目標就是派遣宇航員登陸火星表面，但事實證明這比想象中難度更大。太空處於真空狀態，人類顯得出奇脆弱。宇航員至少需要六個月時間才能抵達火星。在此期間，它們必須要保護自己免受太空高強度輻射的威脅，要承受遠離家園的心理後果，還要準備大量的氧氣。這些還只是登陸火星計劃中的部分問題。
