Lucy (spacecraft)
''Lucy'' is a NASA space probe on a twelve-year journey to eight different asteroids. It is slated to visit two Asteroid belt, main belt asteroids as well as six Jupiter trojans – asteroids that share Jupiter's orbit around the Sun, orbiting either ahead of or behind the planet. All target encounters will be Flyby (spaceflight), flyby encounters. The ''Lucy'' spacecraft is the centerpiece of a US$981 million mission. On 4 January 2017, ''Lucy'' was chosen, along with the Psyche (spacecraft), ''Psyche'' mission, as NASA's Discovery Program missions 13 and 14 respectively. It was launched on 16 October 2021. In November 2023 and in April 2025 it flew by and photographed asteroids 152830 Dinkinesh, Dinkinesh and Donaldjohanson, respectively. Lucy will reach its first main target, the Jupiter Trojan asteroid 3548_Eurybates, Eurybates, in August 2027. The mission is named after the Lucy (Australopithecus), Lucy hominin fossils, because study of the trojans could reveal the "foss ...

617 Patroclus
617 Patroclus ( ) is a large binary Jupiter trojan asteroid. It is a dark D-type asteroid and a List of slow rotators (minor planets), slow rotator, due to the 103-hour orbital period of its two components. It is one of five Jupiter trojan asteroids targeted by the ''Lucy (spacecraft), Lucy'' space probe, and is scheduled for a flyby (spaceflight), flyby in 2033. Patroclus was discovered on 17 October 1906, by astronomer August Kopff at the Heidelberg Observatory in Germany, and was named after Patroclus in Greek mythology. It was the second trojan to be discovered and the only member of the Trojan camp named after a Greek figure, as the convention of naming one 'camp' after Greek figures of the Trojan War and the other after Trojan figures had not yet been established. Patroclus was long thought to be one of the 617 Patroclus#Diameter and albedo, largest Jupiter trojans, with a diameter on the order of 150 km. However, in 2001 it was discovered to be a binary asteroid of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid Belt
The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets. The identified objects are of many sizes, but much smaller than planets, and, on average, are about one million kilometers (or six hundred thousand miles) apart. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. The asteroid belt is the smallest and innermost circumstellar disc in the Solar System. Classes of Small Solar System body, small Solar System bodies in other regions are the near-Earth objects, the Centaur (minor planet), centaurs, the Kuiper belt objects, the scattered disc objects, the sednoids, and the Oort cloud objects. About 60% of the main belt mass is contained in the four largest asteroids: Ceres (dwarf planet), C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
52246 Donaldjohanson
52246 Donaldjohanson ( provisional designation ) is a carbonaceous asteroid from the inner regions of the asteroid belt, approximately long and at its widest point. It was discovered on 2 March 1981, by American astronomer Schelte Bus at the Siding Spring Observatory in Australia. The C-type asteroid was the 2nd target of the ''Lucy'' mission, with the spacecraft flying 960 km (600 mi) from the surface on 20 April 2025, revealing the asteroid to be a contact binary. It was named after American paleoanthropologist Donald Johanson, the discoverer of the "Lucy" hominid fossil. Orbit and classification Donaldjohanson is a member of the Erigone family (), a large carbonaceous asteroid family of nearly 2,000 known members, which is named after its parent body 163 Erigone. The Erigone family is a relatively old family that was created by an asteroid collision approximately 150 million years ago. Since Donaldjohanson belongs to this family, it likely has the same age of 150 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravity Assist
A gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby (spaceflight), flyby which makes use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the Course (navigation), path and speed of a spacecraft, typically to save propellant and reduce expense. Gravity assistance can be used to accelerate a spacecraft, that is, to increase or decrease its speed or redirect its path. The "assist" is provided by the motion of the gravitating body as it pulls on the spacecraft. Any gain or loss of kinetic energy and linear momentum by a passing spacecraft is correspondingly lost or gained by the gravitational body, in accordance with Newton's laws of motion#Newton's third law, Newton's Third Law. The gravity assist maneuver was first used in 1959 when the Soviet probe Luna 3 photographed the far side of Earth's Moon, and it was used by inter ...

Lucy In The Sky With Diamonds
"Lucy in the Sky with Diamonds" is a song by the English rock band the Beatles from their 1967 album ''Sgt. Pepper's Lonely Hearts Club Band''. It was written primarily by John Lennon with assistance from Paul McCartney, and credited to the Lennon–McCartney songwriting partnership. Lennon's son Julian inspired the song with a nursery school drawing that he called "Lucy – in the sky with diamonds". Shortly before the album's release, speculation arose that the first letter of each of the nouns in the title intentionally spelled "LSD", the initialism commonly used for the hallucinogenic drug lysergic acid diethylamide. Lennon repeatedly denied that he had intended it as a drug song, and attributed the song's fantastical imagery to his reading of Lewis Carroll's ''Alice in Wonderland'' books. The Beatles recorded "Lucy in the Sky with Diamonds" in March 1967. Adding to the song's ethereal qualities, the musical arrangement includes a Lowrey organ part heavily treated with stu ...

Lucy (Australopithecus)
AL 288-1, commonly known as Lucy or Dinkinesh (), is a collection of several hundred pieces of fossilized bone comprising 40 percent of the skeleton of a female of the hominin species ''Australopithecus afarensis''. It was discovered in 1974 in Ethiopia, at Hadar, a site in the Awash Valley of the Afar Triangle, by Donald Johanson, a paleoanthropologist of the Cleveland Museum of Natural History. Lucy is an early australopithecine and is dated to about 3.2 million years ago. The skeleton presents a small skull akin to that of non-hominin apes, plus evidence of a walking-gait that was bipedal and upright, akin to that of humans (and other hominins); this combination supports the view of human evolution that bipedalism preceded increase in brain size. A 2016 study proposes that ''Australopithecus afarensis'' was, at least partly, tree-dwelling, though the extent of this is debated. Lucy was named by Pamela Alderman after the 1967 song " Lucy in the Sky with Diamonds" b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
