NASA today decided to postpone the Dawn Asteroid mission again. Read the story here.
The mission is very interesting in the sense that it is the first time we are visiting an asteroid closely. Remember, in most space sci-fi thrillers, mining colonies in asteroid belt is a common story line. It looks like instead of rare, exotic materials like Naquida or something like it, but for water.
My interest in the mission is not colonizing the asteroid belt, but the use of several new technologies that NASA has been putting in the back burner for so long, the ion propulsion drive being the first of them.
I still haven’t figured out why NASA takes at least 100 times more money, time and other resources to do something that you can do otherwise. But hey, it is NASA
