NASA's Lucy mission to launch Oct. 16 to explore Trojan asteroids

NASA to launch Lucy mission to Jupiter’s mysterious Trojan asteroids next month in bid to learn about the formation of the solar system 4.5 billion years ago

  • NASA’s mission to study the Trojan asteroids will launch on October 16
  • It will give experts insight on how the planets formed 4.5 billion years ago and why they ended up where they did
  • It will visit seven Trojan asteroids and one asteroid in the main belt
  • Trojan asteroids orbit the sun in two bands: one in front of Jupiter & one behind
  • These asteroids are made of ancient material that was around as planets formed
  • The 12-year long mission was named for the famous human ancestor and the hit Beatles song, Lucy in the Sky with Diamonds
  • NASA‘s mission to study the Trojan asteroids will launch on October 16, the space agency said late Tuesday.

    In visiting these ancient celestial objects, 미국. space agency hopes to understand more about how the planets formed 4.5 billion years ago and why they ended up where they did.

    Known as the Lucy mission, it will leave from Cape Canaveral Space Force Station at 5:30 오전. ET and explore seven of the Trojan asteroids, that have been called ‘fossilsof the solar system, as well as one asteroid in the main belt.

    ‘추가적으로, Lucy’s path will circle back to Earth three times for gravity assists, making it the first spacecraft ever to return to the vicinity of Earth from the outer solar system,’ NASA said in a 성명서.

    ‘With Lucy, we’re going to eight never-before-seen asteroids in 12 years with a single spacecraft,’ said Tom Statler, Lucy project scientist, in the statement.

    ‘This is a fantastic opportunity for discovery as we probe into our solar system’s distant past.

    The Lucy spacecraft has solar panels on each side to help power its instruments and is 51.8 feet wide and over 46 feet from tip to tip

    The Lucy spacecraft has solar panels on each side to help power its instruments and is 51.8 feet wide and over 46 feet from tip to tip.

    The instruments that will be used to study the asteroidswhich are all different sizesinclude a color visible imager, a thermal emission spectrometer, and a infrared imaging spectrometer.

    During the course of its 12-year long mission, Lucy will travel approximately 4 billion miles.

    The seven Trojan asteroids are named after characters from Greek mythology: Eurybates, Queta, Polymele, Leucus, Orus, Patroclus and Menoetius.

    The Trojan asteroids orbit the sun in two massive swaths - the one in front of Jupiter (L4) and one that is behind it, known as L5

    The Lucy mission, which will last for 12 연령, was named for the famous human ancestor, first discovered in 1974 and the hit Beatles song, Lucy in the Sky with Diamonds.

    Lucy was an adult female of the species Australopithecus afarensis who was found in Ethiopia and is thought to have lived around 3.2 백만년 전

    Her remains are kept at the National Museum of Ethiopia in Addis Ababa and a cast of her remains are on display

    Prior to launch, the Lucy spacecraft will be packed into two halves and NASA engineers will communicate with it via an ‘umbilical cord.

    ‘Launching a spacecraft is almost like sending a child off to collegeyou’ve done what you can for them to get them ready for that next big step on their own,’ said Hal Levison, the principal investigator of the Lucy mission, in the statement.

    In early October, the spacecraft will be sent to Cape Canaveral and ‘matedwith the United Launch Alliance Atlas V 401 rocket that will take it to space.

    Explained: The difference between an asteroid, meteorite and other space rocks

    asteroid is a large chunk of rock left over from collisions or the early solar system. Most are located between Mars and Jupiter in the Main Belt.

    comet is a rock covered in ice, methane and other compounds. Their orbits take them much further out of the solar system.

    meteor is what astronomers call a flash of light in the atmosphere when debris burns up.

    This debris itself is known as a meteoroid. Most are so small they are vapourised in the atmosphere.

    If any of this meteoroid makes it to Earth, it is called a meteorite.

    Meteors, meteoroids and meteorites normally originate from asteroids and comets.

    예를 들면, if Earth passes through the tail of a comet, much of the debris burns up in the atmosphere, forming a meteor shower.
