The moon has been quiet for half a century. That will change in the 1920s. Several space superpowers have announced plans for a return to the moon.
For example, Russia and China have already announced that they will build a moon base together. Others, such as the US, Europe, India and Japan, are also busy.
Return to the moon in this decade
The moon is the closest celestial body and also the only celestial body on which humans have walked. It seems unbelievable, but with the primitive technology of half a century ago, with on-board computers that could do less than those in a bank card now, people landed and walked on the moon. This was mainly due to the then much greater risk appetite. A crew of the Apollo 13 mission did not survive. A few other missions were close. Partly because of this, and the enormous cost, our barren satellite has been quiet for nearly half a century since the last Apollo astronaut took off.
That will change in the 1920s. Various powers have announced plans for a return to the moon. Isaac Arthur here shares the plans of the Americans.
The moon is especially interesting as a transfer point and for mining. The moon's gravity is low, allowing spaceships to take off and land with relatively little fuel. Also nice is that the Moon close to the earth. The moon can be reached with a journey of no more than a few days. All other destinations, such as Mars, Mercury or the outer planets, require months or even years with today's technology. Although there is less to be gained on the moon than at more distant destinations, and the day length and gravity are unfavorable to humans, these advantages outweigh the disadvantages of returning to the moon.
