I imagine...
After flying for nine months the astronauts got to mars it was cold, bleak and not a plant to be seen but when they got to their camp an insulated thermal bubble they couldn't beleave their eyes, there were green grass as far as the eyes could see and a few plant here and there, the atmosphere was so thin that you could see the stars clearly and there was a few small clouds from the plants!
