The US space agency NASA has launched its first Lucy mission to study Jupiter's Trojan asteroids.

  • The Lucy probe was launched on a United Launch Alliance (ULA) Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida on October 16, 2021.
  • Jupiter's Trojan asteroids are two large clusters of space rocks that scientists believe are remnants of the primordial material that formed the solar system's outer planets.
  • The mission life of Lucy is 12-year, during which the spacecraft will fly by a total of eight ancient asteroids to study about solar system's evolution.

Why the name LUCY?

  • There is a reason behind why NASA has named this mission as Lucy. In 1974, a human skeleton was found in Hadar, Ethiopia. After his study, scientists described him as the world's oldest human skeleton ever found. This skeleton was named Lucy (Australopithecine afarensis).
  • To investigate Trojans on Jupiter, NASA has named its mission after the skeleton named Lucy. This spacecraft has gone out in search of fossils that are orbiting the Sun along with Jupiter, millions of kilometers from Earth.
