LARGE REGIONS OF ROCK AND METAL: PSYCHE ASTEROID ILLUSTRATION This illustration depicts the 140-mile-wide (226-kilometer-wide) asteroid Psyche, which lies in the main asteroid belt between Mars and Jupiter. Psyche is the focal point of NASA?s mission of the same name. The Psyche spacecraft is set to launch in August 2022 and arrive at the asteroid in 2026, where it will orbit for 21 months and investigate its composition. Based on data obtained from Earth, scientists believe Psyche is a mixture of metal and rock. The rock and metal may be in large provinces, or areas, on the asteroid, as illustrated in this rendering. Observing and measuring how the metal and rock are mixed will help scientists determine how Psyche formed. Exploring the asteroid could also give valuable insight into how our own planet and others formed. The Psyche team will use a magnetometer to measure the asteroid?s magnetic field. A multispectral imager will capture images of the surface, as well as data about Psyche?s composition and topography. Spectrometers will analyze the neutrons and gamma rays coming from the surface to reveal the elements that make up the asteroid itself. The illustration was created by Peter Rubin.

Spacecraft are heading to a metal asteroid and Jupiter's moons in 2023

28 December 2022

The JUICE and Psyche mission are set to blast off in 2023, with the aim of studying Jupiter's largest moons and a possible iron core of a planet in the hopes of understanding how worlds become habitable

$Mare Crisium is a large, dark, basaltic plain on the Moon that filled an ancient asteroid impact. Basaltic plains on the Moon were created by early volcanic eruptions. Mare Crisium was flooded with basaltic lava, a dark, runny lava commonly found on Earth. Basaltic plains on the Moon are also known as lunar maria, because of a mistaken belief by early astronomers that these dark areas were oceans ? ?maria? is the Latin word for ?seas.? We now know these spots to be plains of basalt created by early volcanic eruptions, but the nomenclature of ?maria? (plural) or ?mare? (singular) remains. The basalts in Mare Crisium range in age from 2.5 to 3.3 billion years old! These dates come from measuring the radioactive isotope signatures of samples returned from Mare Crisium by the Soviet Luna 24 mission. Along the rim of Mare Crisium lies an outer boundary of wrinkle ridges. Wrinkle ridges are commonly found in places where the surface has contracted. As the surface is compressed, it bends and fractures, and can form complicated patterns of faults and folds.$

Bricks made of dust from the moon and Mars could make space buildings

A major component of NASA?s Psyche spacecraft has been delivered to NASA?s Jet Propulsion Laboratory in Southern California, where the phase known as assembly, test, and launch operations (ATLO) is now underway. This photo, shot March 28, 2021 shows engineers and technicians preparing to move the Solar Electric Propulsion (SEP) Chassis from its shipping container to a dolly in High Bay 1 of JPL?s Spacecraft Assembly Facility. The photo was captured just after the chassis was delivered to JPL by Maxar Technologies. Maxar?s team in Palo Alto, California, designed and built the SEP Chassis, which includes all the primary and secondary structure and the hardware components needed for the high-power electrical system, the propulsion system, the thermal system, guidance and navigation sensors and actuators, and the high-gain antenna. Over the next year, additional hardware will be added to the spacecraft including the command and data handling system, a power distribution assembly, the X-band telecommunications hardware suite, three science instruments (two imagers, two magnetometers, and a gamma ray neutron Spectrometer), and a deep space optical communications technology demonstrator. The spacecraft will finish assembly and then undergo rigorous checkout and testing before being shipped to NASA?s Kennedy Space Center in Cape Canaveral, Florida, for an August 2022 launch to the main asteroid belt. Psyche will arrive at the metal-rich asteroid of the same name in 2026, orbiting for 21 months to investigate its composition. Scientists think that Psyche is made up of mostly iron and nickel ? similar to Earth?s core. Exploring the asteroid could give valuable insight into how our own planet and others formed. Arizona State University in Tempe leads the mission. JPL is responsible for the mission?s overall management, system engineering, integration and test, and mission operations.
