NASA launches mission ‘Lucy’ to study Trojan asteroids

NASA has successfully launched the Lucy mission, which is supposed to study the asteroid Donnelandhansson and seven of the Trojan asteroids orbiting Jupiter, on the morning of October 16th.

The mission was launched on an Atlas V rocket made by the United Launch Alliance — previously frozen for launching the U.S. Space Force’s first satellite test, an Orbital Delay Flight 2 test mission involving Boeing Starliner and other missions — from the 41st launch space at the Cape Canaveral Space Power Station in Florida. NASA said it is currently at a speed of 67,000 km / h.

“The name of the fossil skeleton of one of our first known ancestors,” NASA said, “Lucy’s mission will allow scientists to study two swarms of Trojan asteroids that orbit the Sun with Jupiter. Scientific evidence suggests that Trojan asteroids are remnants of matter created by giant planets. Their study can reveal previously unknown information about their formation and the evolution of our solar system in the same way that Lucy’s fossil skeleton revolutionized our understanding of human evolution. “

Lucy will be NASA’s first mission to visit the Trojan asteroids; it will also see the most asteroids among the agency’s missions to date. This whole search will take some time: NASA said it expects the mission to reach Donald Johnson in 2025, encountering asteroids The first Trojans in 2027, and then you will finally see the swarming Trojan asteroid swarm in 2033.

These encounters will be made possible by a series of Earth’s gravity assistants in 2022, 2024 and 2031. The first two assists are supposed to allow Lucy to reach Donnelandhanson and the leading Trojan asteroid swarm, whom the mission with “four focused flies” will see and final assistance should allow. To the trailing swarm of Trojan asteroids 12 years after launch.

“We started working on Lucy’s mission concept in early 2014, so this launch was long in the making,” said Lucy’s managing director, Hel Levison. “It will still be several years before we reach the first Trojan asteroid, but these objects are worth the wait and all the effort because of their immense scientific value. They are like diamonds in the sky.”
