The sky USED to be the limit, but now that NASA is podcasting you'll get your first listen to how the real stars -- along with the moon, Mars, the sun -- help us Earthlings kick off our new year. NASA gives weekly updates on its current endeavors, audio and video features from the NASA website, NASA Brain Bites -- five podcasts in all. You could waste time contemplating what the Mars rover is up to, or what Christmas was like in outer space, or you could let NASA give you the update themselves so you can begin fulfilling your 2006 resolution to rule the world.
