The Night Sky Guy, Andrew Fazekas, talks about his beautiful new, Star Trek-inspired guide to the real wonders of astronomy. Emily Lakdawalla has done wondrous things with images from India’s Mars Orbiter Mission. Bill Nye the Science Guy wants NASA to set a deadline for humans to reach Mars. Don’t mess with Bruce Betts when he tells you what’s up in the night sky. We’ll give away “Star Trek, The Official Guide to Our Universe,” in the space trivia contest.
