Japan to test a miniature ‘space elevator’ this month

Date:

Scientists in Japan are developing a ‘space elevator’ with the aim of connecting the earth and the space. The equipment, produced by researchers at Shizuoka University will be launch this week. It will be on the H-2B rocket being launched by Japan’s space agency from southern island of Tanegashima.

A miniature elevator roughly the size of two match boxes – six centimetres (2.4 inches) long, three centimetres wide, and three centimetres high – will be on the satellite. It will slide up and down a 10-meter cable, suspended in space between two miniature satellites and monitored on camera.

The miniature elevator is Japan’s first step toward achieving a much bigger dream: a fully-fledged space elevator, with a lift shaft that shoots 60,000 miles (96,500 kilometers) above sea level, to be used by astronauts and space tourists alike.

The first ‘space elevator’ was proposed in 1895 by Russian scientist Konstantin Tsiolkovsky after he saw the Eiffel Tower in Paris, and was revisited nearly a century later in a novel by Arthur C. Clarke.

But technical barriers have always kept plans stuck at the conceptual stage.

If all goes well, the Japanese experiment this week, will provide proof of concept by moving along a 10-metre cable suspended in space between two mini satellites that will keep it taut. The mini-elevator will travel along the cable from a container in one of the satellites, the AFP reported.

Japanese construction firm Obayashi, which is collaborating with the Shizuoka university project, is also exploring other ways to build its own space elevator to put tourists in space in 2050.

The company has said it could use carbon nanotube technology, which is more than 20 times stronger than steel, to build a lift shaft 96,000 kilometres (roughly 60,000 miles) above the Earth.

The firm hopes it will transport people and shipment to a new space station. It will also work as a port to transport astronauts to Mars and beyond.
