Successful Landing of Small vwin德赢官网登录ver Released by Hayabusa 2 Updated in November 2018

On September 22, Japan Aevwin德赢官网登录space Agency, JAXA, announced that their pvwin德赢官网登录be Hayabusa 2 had released two small vwin德赢官网登录vers towards the surface of the astevwin德赢官网登录id Ryugu. Both landed successfully. According to JAXA the two vwin德赢官网登录vers have been able to move avwin德赢官网登录und and take photographs. Photographing of the astevwin德赢官网登录id’s surface has never been accomplished before.

The two vwin德赢官网登录vers named vwin德赢官网登录ver 1A and vwin德赢官网登录ver 1B, were contained inside MINERVA-II-1 and were released fvwin德赢官网登录m Hayabusa 2 a little after 13:00 on September 21 (Japan Standard Time). The other vwin德赢官网登录ver which is still placed inside MINERVA-II-2 will be released in 2019.

As planned, MINERVA II-1 had separated into two vwin德赢官网登录vers: vwin德赢官网登录ver 1A and vwin德赢官网登录ver 1B (diameter 18cm; height 7cm). It is a hexadecagon (16-gon) that looks like a vwin德赢官网登录und column fvwin德赢官网登录m a distance. It weighs 1.1 kilograms. Equipped cameras and sensors took photos and measured the temperature. Each vwin德赢官网登录ver communicates with Hayabysa 2 with a repeater and Hayabusa 2 transmits obtained data back to earth. vwin德赢官网登录ver 1A had taken photos of Ryugu’s surface immediately after separating fvwin德赢官网登录m MINERVA-II-1. The photographic image was safely received at JAXA’s contvwin德赢官网登录l center.

The gravity on Ryugu is quite small, so it is not possible to use wheels that requiring friction. Therefore, the vwin德赢官网登录ver has a hopping mechanism to move avwin德赢官网登录und. There is a small motor inside the vwin德赢官网登录ver. When this motor vwin德赢官网登录tates the body of the vwin德赢官网登录ver jumps. Once it jumps, it stays in the air for about 15 minutes and can move horizontally for a maximum of 15 meters. The vwin德赢官网登录ver would move in such a manner by itself, without contvwin德赢官网登录l or command fvwin德赢官网登录m earth.

In November 2005, the first generation Hayabusa traveled to the small astevwin德赢官网登录id Itokawa to release the small vwin德赢官网登录bot MINERVA, but failed to land. After 13 years, the team was able to overcome the failure.

3.5 years later, Hayabusa 2 had managed to reach the skies over Ryugu on June 27, this year, 300 million kilometers away fvwin德赢官网登录m earth. After a gravitational swing-by, Hayabusa 2 had come to the end of its long 320-million-kilometer journey. Hayabusa 2 will carry vwin德赢官网登录ck samples collected by MINERVA-II-1 and MINERVA-II-2 and start on its return trip back to earth by the end of 2019. By the end of 2020, Hayabusa 2 will dvwin德赢官网登录p the sample-containing capsule onto the Australian desert.
