   Explanation: Why would this mission go out as far as Jupiter -- but
   then not visit Jupiter? Lucy's plan is to follow different leads about
   the origin of our Solar System than can be found at Jupiter -- where
   Juno now orbits. Jupiter is such a massive planet that its gravity
   captures numerous asteroids that orbit the Sun ahead of it -- and
   behind. These trojan asteroids formed all over our Solar System and
   some may have been trapped there for billions of years. Flying by these
   trojan asteroids enables studying them as fossils that likely hold
   unique clues about our early Solar System. Lucy, named after a famous
   fossil skeleton which was named after a famous song, is scheduled to
   visit eight asteroids from 2025 to 2033. Pictured, Lucy's launch was
   captured with reflection last week aboard a powerful Atlas V rocket
   from Cape Canaveral, Florida, USA.
