A Japanese spacecraft has landed on a faraway asteroid, where it will collect space rock that may hold clues to how the Solar System evolved.

The successful touchdown on the Ryugu asteroid was met with relief and cheering in the control room at Japan’s space agency, JAXA.

It is the second landing for the unmanned Hayabusa-2, which touched down on the asteroid in February.

After blasting a crater into Ryugu, it has returned to pick up fresh rubble.

As the samples will come from within the asteroid, they will not have been exposed to the harsh environment of space.

It’s hoped the rock will give scientists more data on the origins of the Solar System.

Hayabusa-2 is due to bring the specimens back to Earth next year.

Left over from 4.5 billion years ago

Ryugu belongs to a particularly primitive type of space rock, left over from the early days of our Solar System.

It may therefore contain clues about the conditions and chemistry of that time – some 4.5 billion years ago.

  • Spacecraft’s ‘bomb’ crater found

Hayabusa-2 started its mission to reach Ryugu in 2014, launching from Japan’s space port Tanegashima.

The asteroid is a 900m-wide space rock, about 290 million km (180 million miles) from Earth.

Ryugu holds key clues into the origin of the Solar System

Asteroids are essentially leftover building materials from the formation of the Solar System.

It’s also thought they may contain chemical compounds that could have been important for kick-starting life on Earth.

They can contain water, organic (carbon-rich) compounds and precious metals.

The last of those has even tempted several companies to look into the feasibility of asteroid mining.
