Tonight a Dragon be launched

Helios
Whilst we all hope space X launch goes well , apparently we should be able to see it from UK is sky stays clear , at around  8:30pm when you spot the International space station (ISS) , at :8:50 you should see the dragon space capsule moving towards it , although still be pretty light in sky , but its hard not to miss ISS as its a bright as venus has been.

I don't know if general space travel gets discussed on community message boards , but it is rather energy intensive and polluting as a tourism idea and am a bit puzzled why NASA wants to go to moon when we can already get to mars and supply it , but the supply system to mars even for 12 people would be massive , at around 1/3 the size of the earth and an ave temp of -35oC , its going to pretty hard to grow crops and magnetosphere is less (but not as less as the moon) so high radiation levels possible .

    Yes it is technically a difficult environment and engineering challenge , I think it takes 14 months to get there and how you get back is a real challenge , but my thinking is you put the cost of the moon base into the more expensive mars mission , be a really big supply train, probably a sort of space station for mars with a docking for your space travel ships and some sort of drop system to surface , then you don't have all the hassle of trying to lift from mars surface with a large ship.
