Lucy’s work takes its moniker from the slightly excavated bones of an ancient human ancestor, Australopithecus afarensis, discovered in 1974, that changed the notion of human origin and evolution. The research team hopes that the spacecraft will support the planetary science that those fossils did in paleoanthropology, by giving us the shape and evolution of our solar system.
In the early days of the sun, the debris was surrounded by a rotating disk around a small Sun. The metal pieces connect, grow snow, and mature on the beautiful planets we see today. Asteroids actually lose a pile from there. “It’s a residue from the earliest times before the planets,” says Tom Statler, a Lucy scientist at NASA.
He compares the study of asteroids with the study of pyramids – such as the pyramids, in this image, and Jupiter, Saturn, Uranus, and Neptune, and Trojan asteroids were developed. You can just find out more about how these great buildings came to be from the three completed triangles. Find a construction site, and you can learn more about their brand. “The items that eventually became Trojans were made all over the sun and were transported to be seized right now,” Statler said. “The Trojans are some of the remains that were swept away and left there.”
And although our planet is rocky, not a gas giant, studying the outer planets gives us insight into how they were made. “It’s clear and clear that no planet is perfect,” said Statler. “Earth is what it is because the sun is what it is … In order to understand the Earth, we need to understand how other planets were created and developed.”
Lucy relied on three major weapons: L’LORRI, L’TES, and L’Ralph. The original “L” means it is part of Lucy’s work, because everything is placed on equipment that has already flown. LORRI and Ralph were weapons inside New Horizons work in Pluto with a Kuiper belt. “L’LORRI,” that is, means “Lucy Lorri,” says Michael Vincent, chief executive of the Southwest Research Institute’s space department. OTES was part of OSIRIS-REx flights that asteroid Bennu. “The devil we know is what we want to stick to,” says Vincent. (Also, one of the scientists on the project has a French history and was, Vincent’s joke, “trying to figure out the place.”)
L’LORRI is actually a beautiful camera, big enough that it can take pictures of 200-foot craters from 600 miles away, and map them to reveal the history of the asteroid. It can search for rings and satellites, and helps Lucy navigate to asteroids. Other than that, choosing a remote drop to consider is not easy. “These things aren’t good out there, and we’re starting to split,” says Vincent.
L’TES works as unconnected thermometers that you can detect from Covid-19 flashlights, but instead of directly on the forehead, the instrument points to an asteroid position and takes its temperature by detecting the infrared temperature from which it emits. “Over time,” says Vincent, “you get the whole picture by looking at different locations,” says Vincent. Their purpose is to measure “inertia inertia,” or to run or cool as much asteroid temperature or cooling — an indication of the material being formed. For example, the sand retains some of the heat as opposed to the rock, which you may have noticed if you have traveled long distances in the setting sun.
