From Earth? Because those things are small and we're far away.
How small? The biggest things left behind by the Apollo missions were abour 20 feet wide. When we point Hubble at the moon it has a resolution of about 100 feet per pixel.
Europe's SMART-1 satellite took pictures from orbit around the moon and I think it never had a resolution better than 50ft per pixel or so.
Keep in mind that all those really high resolution photographs in Google Earth are taken from airplanes only a half dozen miles away at most.
