Meteorites, ores and rare metals are the subjects of an unusual exhibition in Tokyo and may be visited until September 29.
The University of Tokyo’s museum is sponsoring the exhibition, with the aim of prompting visitors to consider how to obtain natural resources that are running out. The display includes a 2 centimeter fragment of a meteor that fell in Chelyabinsk province in central Russia in February.
The fragment contains more platinum and iridium than ores found on Earth. This suggests that similar asteroids could be a potential source of natural resources in the future.
The visitors may also admire a meteorite believed to have fallen in present-day Africa about 450 million years ago. The meteorite is over 90 percent iron and contains about 3 times the amount of iron than ores produced on Earth.
Mud containing rare earths is also being exhibited. A university team collected the sample from the seabed near Japan’s eastern tip in the Pacific.
Associate professor Hideaki Miyamoto, involved in the organizing of the event said to the media that he hopes that the exhibition will prompt visitors to consider whether to look to space for resources or to invent new ways of making good use of the Earth’s limited supply.
