Five things to know about NASA's mission to a metal world

Sensitive instruments to explore metal-rich asteroid

At the very center of the Earth is a core of metal—so hot and so deep down as to be unreachable and impossible to study directly. But we might learn more about it and the cores of other Earth-like planets by studying the asteroid Psyche. Based on observations made through telescopes, it is believed to consist of 60% metal, probably an iron and nickel alloy. Looking a bit like a potato and measuring about 150x250 km, Psyche may be the innermost core of a planet that, following a violent collision with another object, was stripped of its outer crust.
NASA is scheduled to send a mission to Psyche on Oct. 13. It will be NASA's fourteenth Discovery Program mission. Preparations started in 2017 with launch planned for 2022, but due to the corona pandemic, NASA was unable to complete the necessary testing in time.
China is planning to double the size of its space station

The International Space Station (ISS) will be retired in 2030 after more than 32 years of continuous service. Naturally, there are questions regarding what will replace this station, which has served as a bastion for vital research and inter-agency cooperation in space. In the past, China has indicated that their Tiangong ("heavenly palace") space station will be a successor and rival to the ISS, offering astronauts from other nations an alternative platform to conduct research in Low Earth Orbit (LEO). As part of this plan, China recently announced plans to double the size of Tiangong in the coming years.
This announcement was shared last Wednesday, October 4th, during the 74th International Astronautical Congress (IAC 2023) in Baku, Azerbaijan. According to the China Academy of Space Technology (CAST), three new modules will be added to Tiangong, which currently consists of the Tianhe Core Cabin Module (CMM) and two Laboratory Cabin Modules (LCM)—Wenhian ("Quest for the Heavens") and Mengtian ("Dreaming of the Heavens").
