At that instant, Tang Yue felt as though he had returned to a century ago in the era of Yuri Gagarin and Alan Shepard. The engineers had given their all to construct a launch pad weighing hundreds of tonnes and used the R-7 and Redstone rockets that weighed nearly thirty tonnes to send a payload of 70 kilograms.
That was extremely disproportionate in terms of mathematics and physics, with them spending massive amounts of resources to ultimately concentrate on such an individual.
A long period of time had passed, and during this time, humans gained the ability to build space stations, to land on the moon, and to head for Mars. However, they had forgotten that all of that once started from careful micro-steps. In the early days, liquid oxygen and ethanol engines that were sent to near-Earth orbit had a carrying capacity of fewer than three tonnes and the manned spacecraft was only two meters long.
