Hayabusa2 stops short of close approach on first touchdown rehearsal

Emily Lakdawalla • September 13, 2018

Hayabusa2 didn’t quite make it down to its intended 60-meter distance from asteroid Ryugu yesterday. There is nothing wrong with the spacecraft; it’s healthy and returning to its home position. The team will adjust parameters and give it another try in the future.

Hayabusa2 prepares to collect samples, leave Planetary Society names on Ryugu

The names were collected by the Society in 2013, and are stored on target markers that will be dropped on the asteroid.

Hayabusa2 Team Announces Ryugu Landing Sites, Initial Science Survey Results

Emily Lakdawalla • August 24, 2018 • 3

Two months after arrival, the team has reported some preliminary facts about Ryugu. They also announced the selection of candidate landing sites for the spacecraft sample collection, for the German-built MASCOT hopper, and for the MINERVA-II microrovers

Hayabusa2 descends again, this time to lower than 1000 meters above Ryugu

This week Hayabusa2 completed its closest approach yet to asteroid Ryugu. In a successful gravity measurement experiment on August 6, the spacecraft dipped to within 1 kilometer of the asteroid.

A second successful medium-altitude operation for Hayabusa2

For the second time, JAXA navigators have zoomed their cameras and other instruments in on asteroid Ryugu. The August 1 operation was quicker than the previous one, requiring only 26 hours for the descent, science, and ascent.

Hayabusa2 descends from Home Position to take its first close look at Ryugu

Last week, Hayabusa2 approached to within 6000 meters of the surface of Ryugu, taking new photos. The team has developed a set of terminology to describe Hayabusa2's navigational positions around the asteroid.

New goodies from asteroid Ryugu!

Two new global views of Ryugu from Hayabusa2, plus a 3-D animation.

What's the benefit of sample return?

Jason Davis • July 05, 2018 • 1

With Hayabusa2 at Ryugu and OSIRIS-REx closing on Bennu, it's the summer of sample return. Why do scientists go to so much trouble for a piece of a another world?

Hayabusa2 arrived at Ryugu, so I can make comparisons of asteroid scales!

Emily Lakdawalla • June 27, 2018 • 2

On 26 June 2018, Hayabusa2 arrived at its target asteroid, Ryugu. In a very brief status update, I present comparisons of Ryugu to other previously visited asteroids and comets.

Hayabusa2 update: New views of Ryugu and corkscrew course adjustments

Emily Lakdawalla • June 21, 2018 • 2

Ryugu has continued to grow in Hayabusa2's forward view, resolving into a diamond-shaped body with visible bumps and craters! They've done hazard searches, optical navigation imaging, and measured the rotation rate at 7.6 hours.
