NASA launches Lucy mission to explore asteroids over Jpiter

The spaceship Lucy, NASA’s first mission to investigate Trojan asteroids in orbit over Jpiter, took off this Saturday (12) in the United States, for some trip about 12 years. The initiative seeks to better understand the carry out formation of our photo voltaic system.

The Atlas Sixth is v rocket, in charge of boosting the ship, left t 6h24 zero hours over Brasilia over Cape Canaveral, Florida.

the first sun energy ship to ze to venture so far perform Sol. Observe more asteroids than any other ship before: eight in overall.

Each of these asteroids must “offer some part of a story that performs our photovoltaic system, a story of ours,” Thomas Zurbuchen, director of an agency’s science division, declared at the press conference american space.

Around about 2025, Lucy overflying an asteroid from a primary belt, situated between Mars electronic Jpiter, before about visiting seven Trojan asteroids, operating system two last na2033. A wider one measures about about 34 kilometers over diameter.

Sony ericsson spacecraft approaches 2 asteroids the some distance between 95 electronic 95 kilometers, depending on their size, the fence about 95 million km/they would.

About about 7.000 Trojan asteroids are known. Therefore “very different from each other,” explained Hal Levison, the mission’s primary researcher. “Some therefore gray, some red,” he said.

The mission was called about Lucy in reference to the australopithecine fossil discovered in Ethiopia in 1974, which helped to clarify the origin of a humanity. NASA now intends to clarify the evolution of the sun system.

The spacecraft will carry a diamond that will measure the infrared light, which will allow it to determine the temperature on the surface of 2 asteroids.

“By comparing these measurements on electronic night over day, we can determine the learning surface made on blocks on rock, or on fine electronic dust sand,” explained Phil Christensen, responsible for the scientific instrument called L’TES, which contains a diamond. Rock cools less quickly than sand at night. The mission cost is about US$ 981 million (more than Ur$5.3 billion).
