The Christian Science Monitor has a good article, What’s next for US spaceflight, if not the moon? geared for those who may not follow space news daily. Yes, believe it or not, they exist and they are called…people.
The CSM’s article does a good job of posing questions such as, Where would NASA fly in the future, and when? or Why bother with human spaceflight at all? and then tries to answer those questions in a lucid and approachable manner. The article does talk about the changes the Obama Administration wants to make to NASA, their likely impact, and even their unlikely chances.
For those unsure of what Constellation is, why human space flight is important, or what changing to the flexible path could mean, What’s next for US spaceflight, if not the moon?, is a great place to start learning.
