Here a beautiful visualization of space mission conducted for the last 50 years. This should be the image they should be taking to get funding for space programs. Look at the space crafts that were launched in 1950 and 1960. It would have been costly at that time, but they are such useful things to do for the advancement of human race.
Hope images like this will keep the funding coming and we will have a good space program.
Download this photo for yourself, it would make a lovely wallpaper.
