NASA is landing a Mars rover named Curiousity this weekend (Sunday night if you want to watch), and if it all goes well it will be an amazing accomplishment.  Check out the video they put together explaining how it all works, including the ‘7 minutes of terror’ during which the little space craft will be out of touch entirely.  Consider taking yourself out of touch entirely for 7 minutes – could you walk away from your phone, email, GPS, TV, tablet, etc. for 7 whole minutes?  Might be harder than you think!
