  • Asteroid Ryugu

The Yomiuri ShimbunJapanese asteroid explorer Hayabusa2 reached a point about 20 kilometers above its target asteroid, Ryugu, at 9:35 a.m. Wednesday, after having left the Earth at the end of 2014, the Japan Aerospace Exploration Agency announced Wednesday.

From a distance, Ryugu initially appeared round, then gradually turned into a square before becoming a handsome shape similar to fluorite.

Ryugu's shape resembles a spinning top and measures 900 meters in diameter.

"From a distance, Ryugu initially appeared round, then gradually turned into a square before becoming a handsome shape similar to fluorite [known as the "firefly stone" in Japanese]", said project manager Yuichi Tsuda.

Landings are planned for September as well as February and April next year.

Hopefully, by 2019, Hayabusa2 will make its way back to Earth just to be in time to eject a capsule containing the samples to Earth by 2020.

It also said it is equipped with three miniature rovers which can roam the surface of the asteroid and conduct close-up probes.

He said asteroids with this general shape tended to be fast-rotating, completing one revolution every three or four hours.

While noting that nothing has been decided regarding another launch, he said, "I feel that I would like to keep giving it a shot". About 600 people who had gathered to observe the launch in the Hokkaido town watched as the rocket fell from the sky in flames.

He "rapidly accelerated, through a stop sign and across a raised pedestrian mall, and drove directly into the crowd", it said. Prosecutor Joseph Platania said in a statement that the federal indictment would have no effect on the pending state case.

Ryugu is classified as a potentially hazardous asteroid, meaning it has an orbit around the sun that could bring it close to earth and it is of sufficient size to cause significant damage if it hit. The asteroid's craters, as well as geographical features, also become visible.

From this crater, the probe will collect "fresh" materials unexposed to millennia of wind and radiation, hoping for answers to some fundamental questions about life and the universe, including whether elements from space helped give rise to life on Earth. Its Osiris-Rex spacecraft is expected to reach the asteroid Bennu later this year and return with samples in 2023.

Scientists want Hayabusa 2-which will probe Ryugu with a number of smaller rovers and instruments-to return samples from the asteroid's surface. In 2006, the first Hayabusa craft managed to touch down on the surface of the near-Earth asteroid Itokawa three times - revealing that instead of being a chunk of solid rock, the asteroid was essentially "a bunch of rubble being held together by shared gravity", as NPR's Joe Palca reported.

The spacecraft, after its journey of 3½ years, is now going to start its real work of endeavoring to blow the crater, in order to collect samples to bring them back to the Earth, eventually.

Pictures taken by Hayabusa Two's ONC-W1 (Optical Navigation Camera - Wide angle) on June 24 show Ryugu is roughly shaped like an eight-sided dice. The image was taken in the distance of about 40 kilometers (25 miles) between the explorer and the asteroid.

Earlier images taken 62 miles to 124 miles (100 to 200 km) from Ryugu suggest the asteroid had a complex evolutionary history, according to Jaxa.
