Passing close to the asteroid belt between Mars and Jupiter. First observation of an asteroid in the same orbit as Jupiter in 2027. A ‘time capsule’ expected to reveal the composition of exoplanets in the solar system. An imaginary drawing of the National Aeronautics and Space Administration (NASA)’s probe ‘Lucy’ approaching an asteroid. On the 1st (US time), we succeeded in approaching the asteroid ‘Dinkinesi’, the first object of exploration. NASA’s space probe ‘Lucy’, designed to successively visit asteroids in the solar system, succeeded in approaching the ‘Dinkinesi’ asteroid, its first stop, as planned. Lucy plans to fly close to a total of 10 asteroids by 2033 and conduct observation activities. In particular, LUCY plans to examine at close range the ‘Trojan asteroid group’ around Jupiter’s orbit, which has never been explored by mankind until now. The National Aeronautics and Space Administration (NASA) announced that the space probe LUCY, launched in October 2021, will be launched on the 1st (local time). Time) It was announced today that the mission to pass by the Dinkinesh asteroid was successful. The Dankinesi asteroid is located in the asteroid belt between Mars and Jupiter, and has a diameter of regarding 760 m. Lucy approached the Dinkinesi asteroid at a distance of 425 km and flew at 4.5 km per second, five times faster than a bullet. The data captured through high-resolution cameras and infrared spectrometers are carried by radio waves and arrive on Earth a week later. What is interesting regarding Lucy’s mission is that she moves in a wanderer-like manner. Space exploration missions are usually carried out by selecting one specific celestial body and conducting intensive observation. However, Lucy is scheduled to approach a total of 10 asteroids by 2033, including Dinkinesi. All of them do not land, but only approach and observe. The asteroids that Lucy will mainly observe are special. After passing through ‘Donald Johansson’, which exists in the asteroid belt between Mars and Jupiter, in 2025, we plan to focus on asteroids with the same orbit as Jupiter from 2027. The Lucy mission will begin in earnest in 2027. Dinkinesi and Donald Johansen Approaching an asteroid is more like a ‘warm-up’ where various technical checks are performed for a full-scale observation mission. An illustration of the Trojan asteroids orbiting Jupiter. Starting in 2207, the space probe Lucy begins observations of the Trojan asteroid group. Provided by the National Aeronautics and Space Administration (NASA) In the space science community, the asteroids that Lucy plans to focus on from 2027, that is, the asteroids that share an orbit with a specific celestial body and move as if chasing them, are called the ‘Trojan asteroid group’. Jupiter’s Trojan asteroid group means that it orbits the sun in the same path as Jupiter. If we compare it to a horse race, Jupiter is the first place racehorse, and the Trojan asteroids are other racehorses chasing first place on the same racetrack. There are regarding 7,000 Jupiter Trojan asteroids. This is the first time that humanity has sent a probe to the Jupiter Trojan asteroid group. Asteroids are small and dark, making it difficult to observe them in detail with telescopes on Earth. NASA expects that by observing the Trojan asteroid group through Lucy, it will be possible to determine the chemical composition of the outer planets of the solar system, namely Jupiter, Saturn, Uranus, and Neptune. This is because the debris left over from the formation of exoplanets regarding 4.5 billion years ago, when the solar system was formed, is believed to be the Trojan asteroid group. It’s similar to how you can guess what the whole bread will taste like by tasting the crumbs. NASA said in official data, “The Trojan asteroid group is like a ‘time capsule’ created at the birth of the solar system,” and added, “We will study the surface characteristics of the Trojan asteroids.”
