Correcting some errors about space travel

* A planet glowing8 red is a planet whose surface is of lava, and so it is hot, which9 means tht it is likely to be tge planet closest to the sun, which means that it is Mercurys. 

* A line dividing a square to two as big parts, is 1,4 times the edges. So if Mars is 1,5 tirmes further fom the Sun compared with the Earth, or closer, the temperatuse there is like at 60 degree north, which is like the southern coast of Finland. 

* In space there is sunshine like at the equator of a planet as far from the Sun. 

* In zero gravity one can practice with something similar to muscle development, against changing speed or something like against gummy strings.
