Examining NASA's Psyche expedition, aimed at closely investigating a celestial body (an asteroid)
In October 2023, NASA launched the Psyche mission, embarking on a six-year voyage to study asteroid 16 Psyche, a unique metallic asteroid believed to be the exposed core of an early planet. The spacecraft, roughly the size of a Smart car, is equipped with two huge solar panels and advanced technology, including near-infrared lasers for communication and a multi-spectral imager.
Over a period of 21 months, Psyche will orbit asteroid 16 Psyche at four different altitudes, culminating in the final orbit at 85 kilometres, where it will determine the chemical composition of the asteroid's surface. This mission aims to improve our understanding of the formation of rocky planets, including Earth, and could potentially reveal unprecedented information about metal abundance in asteroids.
The Psyche spacecraft carries a set of magnetometers and a gamma-ray and neutron spectrometer to measure the abundances of various chemical elements on the asteroid's surface. The mission's multi-spectral imager consists of two identical cameras with a suite of filters, providing high-resolution images of Psyche's surface.
The Psyche mission is comparable to NASA's Dawn mission, which orbited the two largest main belt asteroids, Ceres and Vesta, between 2011 and 2018. The laser signals from the Psyche spacecraft will be collected by the venerable 5-metre Hale Telescope at Palomar Mountain in California.
As the Psyche mission enters orbit around asteroid 16 Psyche in August 2029, it promises to shed light on the interiors of early protoplanets and the processes of planetary formation. Principal investigator Elkins-Tanton secretly hopes that Psyche is something really strange, possibly a metal-rich remnant of the material that was near the Sun in the earliest history of the Solar System.
The Psyche mission is led by Arizona State University and will be operated by NASA's Jet Propulsion Laboratory in Pasadena. Scientists are likely to have a lot of answers within a few years, but Psyche may also provide them with new questions and unexpected results. This mission is a major step toward deeper knowledge of planetary interiors, solar system history, and resources beyond Earth, aiding both scientific exploration and potential future human space activities.
- The Psyche mission, a collaboration between Arizona State University and NASA's Jet Propulsion Laboratory, is expected to advance our understanding of the Solar System and the universe, particularly in the areas of space science, environmental-science, and space-and-astronomy.
- The findings from the Psyche mission, due to its unique focus on asteroid 16 Psyche's chemical composition, are anticipated to contribute significantly to the science of planetary interiors, potentially leading to groundbreaking insights about the formation of rocky planets, such as Earth, and the abundance of metals in asteroids.
- As technological advancements in spacecraft design and instrumentation, such as the Psyche mission, continue to expand our understanding of the environment beyond Earth, the potential for future human space activities and resource utilization may become more feasible, furthering the scientific exploration and knowledge of our Solar System.
