“Lucy is in the sky!” NASA announced at 9:34 GMT (6:34 in Brazil) on Saturday on its Twitter accounts.

And the US space agency was referring to the launch of the Atlas V rocket aboard the Lucy spacecraft, The first spacecraft designed to study Trojan asteroids on Jupiter.

Lucy embarked on a 12-year journey to study eight different asteroids: one in the main belt between Mars and Jupiter and another seven located in the region called Troy. The goal is to gain new perspectives on the formation of the solar system 4.5 billion years ago.

Trojan asteroids, according to mission scientist Hal Levison, are physically different from each other. “For example, they have very different colors, some are gray, some are red,” he explained at a news conference on Friday (15). The differences indicate how far away they may have formed from the Sun before taking their current trajectory.

“Whatever Lucy discovers, it will give us vital clues to the formation of our solar system,” said Laurie Glaze, director of NASA’s Planetary Science Division.

At around 7:40 AM (Brazil time), Lucy successfully detached from the rocket and is now traveling alone toward the asteroids. NASA scientists, who were watching the Florida control room launch, celebrated the moment with a round of applause.

Scientific evidence, according to NASA, indicates that the asteroids of Troy are the remnants of the material that formed the giant planets. Studying her could reveal previously unknown information about the formation and evolution of our solar system, just as Lucy’s fossilized skeleton revolutionized science’s understanding of human evolution.

The probe will fly over an asteroid between Mars and Jupiter for the first time around 2025.

“It will take several years before we reach the first Troy asteroid, but it will be worth the wait and all the effort because of its tremendous scientific value. They are like diamonds in the sky,” said Hal Levison.

Lucy is the first solar-powered spacecraft to venture very far from the sun. To do this, she carries on board two huge solar panels, each approximately 7.3 meters wide.

The cost of the mission is approximately $981 million.
