NASA’s Lucy mission began early Saturday at the agency Kennedy Space Center in Cape Canaveral, Florida.
Lucy, Troy’s first mission to Jupiter’s asteroid, will travel approximately 4 billion miles and take off on the United Launch Alliance (ULA) Atlas V rocket.

Lucy’s main mission is almost 12 years, during which she visits eight asteroids (main belt asteroid and seven Trojan horses) that share an orbit with Jupiter at the planet’s Lagrange point.
The Lagrange point is the location around the planet’s orbit where the gravitational pull of the planet and the sun and the movement of the orbit combine to form an equilibrium.
Asteroids are thought to be the debris of the primitive materials that formed the outer planets, and scientists say that studying asteroids provides important clues about the formation of the solar system.
In history, NASA has no other space mission launched to many different destinations in independent orbits around the Sun.
Lucy – traveling at average cruising speeds of 39,000mph and 15,000mph when flying each asteroid – is the first to travel a little further than Jupiter’s distance and return closer to Earth for final gravity assist. It can also be a spaceship. It sends it back to the last Trojan encounter.
Scientists select several targets to study and use some equipment to collect visual, constructive, and physical information.
With two giant solar panels needed to power the spacecraft, Lucy, over 51 feet wide, has the high-gain antennas needed to communicate with the Earth inside the spacecraft’s body.
In its body, the Lucy Thermal Emission Spectrometer (L’TES) measures the surface temperature of the asteroid by observing the thermal infrared spectrum, and the Lucy Long Range Reconnaissance Imager (L’LORRI) is a high-resolution panchromatic. Visible Cameras Provide Details Surface Images and L’Ralph have infrared imaging spectrometers that reveal absorption lines that act as fingerprints for various silicates, ice, and organics. The L’Ralph Multispectral Visible Imaging Camera (MVIC) is also a Trojan horse that helps determine the configuration.

Lucy can also use a terminal tracking camera (T2CAM) to track asteroids passing within 600 miles of each target.
In addition to spectrometers and robotic cameras, Lucy uses Doppler traces to measure mass.
In addition, Lucy operates farther from the Sun than any other solar-powered spacecraft to date.
At 7:09 am eastern daylight saving time, NASA tweeted that the $ 981 Lucy mission “has successfully deployed solar panels and is now officially on a grand journey to Jupiter’s Trojan asteroid.”
Lucy is big Artificial diamond This mission of splitting rays with a far-infrared spectrometer is not named after the Beatles’ famous “Lucy in the Sky with Diamonds”.
Instead, Lucy was discovered in Ethiopia in 1974 and was chosen in honor of the fossilized human ancestor of the same name.
Paleoanthropologist Donald Johanson, who discovered the fossil, said in an interview from Lucy’s launch site, “Being here this morning is absolutely open-minded … what the creativity of the human mind does. To see if we can do it. ”

At the end of the mission, Lucy continues in a stable orbit, moving from near Earth’s orbit to a herd of Trojan horses.
“The team carefully planned to prevent Lucy from colliding with the Earth or contaminating places where life could exist for more than 100,000 years,” NASA wrote on its website. “If future humans do not collect Lucy as an early historical relic of solar system exploration, Lucy’s orbit will eventually become unstable and Jupiter will probably send a spacecraft to or throw it out of the solar system.”
