News Excerpt
A recent study has found that asteroid 16 Psyche, which orbits between Mars and Jupiter, could be made entirely of metal and is worth an estimated $10,000 quadrillion — more than the entire economy of Earth.
NASA’s Psyche mission
The Psyche mission is a journey to a unique metal asteroid orbiting the Sun between Mars and Jupiter. What makes the asteroid Psyche unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system.

About asteroid 16 Psyche
•    First discovered in 1853, located around 370 million kilometres away from Earth, asteroid 16 Psyche is one of the most massive objects in the asteroid belt in our solar system. The somewhat potato-shaped asteroid has a diameter of around 140 miles.

Is the asteroid really worth $10,000 quadrillion?
    NASA scientists believe that the asteroid is made up of almost entirely of iron, nickel and several other rare materials like gold, platinum, cobalt, iridium and rhenium.
    Hypothetically, if it was to be transported to Earth, NASA has calculated that the iron alone would be worth more than $10,000 quadrillion.
    However, NASA clarified that there was no way for the asteroid to actually be brought back to Earth as we lacked the technology to do so.

Highlights of the latest study on asteroid 16 Psyche
    The study involved the first ultraviolet observation of Psyche, offering a clearer picture of the asteroid’s composition for the first time.
    Unlike most asteroids that are made up of rocks or ice, scientists believe that Psyche is a dense and largely metallic object thought to be the core of an earlier planet that failed in formation.
    Metal asteroids are not commonly found in the solar system, and scientists believe that studying 16 Psyche may offer a rare glimpse of what the inside of a planet really looks like.


Chang’e -5 probe
About Chang’e -5 probe
•    The Chang'e-4 lunar probe mission - named after the moon goddess in Chinese mythology is humanity's first probe to land on and explore the far side of the moon.
•    No lander or rover has ever touched the surface there, positioning China as the first nation to explore the area.
•    Unlike the near side of the moon that is "tidally locked" and always faces the earth, and offers many flat areas to touch down on, the far side is mountainous and rugged. It was not until 1959 that the Soviet Union captured the first images of the heavily cratered surface, uncloaking some of the mystery of the moon's "dark side".
•    A major challenge for such a mission is communicating with the robotic lander: as the far side of the moon always points away from earth, there is no direct "line of sight" for signals. As a solution, China blasted the Queqiao ("Magpie Bridge") satellite into the moon's orbit, positioning it so that it can relay data and commands between the lander and earth.

Recent Findings
    So far, the probe has survived on the far side of the Moon for 630 Earth days, equivalent to 45 lunar days, and the rover has travelled 547.17 meters.
    The rover also explored the impact crater about 1.3 kilometres northwest of the landing site and the areas with high reflectivity.
    With the panoramic camera, infrared imaging spectrometer and lunar radar, the rover can peer beneath the surface of the mysterious far side of the Moon, based on which multiple achievements have been made and published recently in the journal Nature Astronomy.
    The scientific team carried out in-depth study on the radar detection data and obtained important findings on the lunar soil and shallow structure of the landing area.
    The latest discoveries are of great significance for understanding the evolution of the South Pole-Aitken basin of the Moon, as well as for the future exploration and study on the composition and structure of the lunar interior.
