The following link is a news article about a project called “Large Synoptic Survey Telescope”. The $400-million project tries to build a telescope to survey the entire sky every three nights for ten years. Honestly this is not the first “science” project that has its way to waste money in history. Nowadays people just obsessed with collecting data, any kind of data from any sources; indeed the biggest problem is what to do with all the data? Unfortunately Hollywood always tells the public that it is quick and easy to find, say, a person from various surveillance cameras but this is a huge job indeed. If it is so easy to do, Mr. bin Laden won’t be still at large at this time. All these imageries require analysts to examine inch-by-inch before one photo is found to be useful. The problem with the American military is not they don’t have enough airborne surveillance platform but they don’t have enough eyes to analyze the imagery data. (Infrared, SAR or hyperspectral imageries even require trained eyes.) In the case of astronomy, I believe most discoveries by using Hubble Telescope came from imageries that were taken a long while ago. It takes time and expertise to examine these photos. What good does it do to stream the imageries of the entire night sky to the internet for the general public? Yes, perhaps we now have the technology to do this kind of survey but we must think beyond achieving the technology milestone.
