Today NASA's Curiosity Rover landed on Mars.
Its advanced instruments should bring humanity closer to knowing whether life exists on the Red Planet. I discussed the " Spiritual Significance of Mars " during that planet's closest approach to Earth in human history.
I believe that private companies will lead the way to humans landing on Mars. SpaceX founder Elon Musk has said Mars is his ultimate target. In " SpaceX's Entrepreneurial Triumph ," you can read my reflections on the recent successful berthing of that company's Dragon capsule with the International Station.
