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

Emily Lakdawalla • August 10, 2018 • 2

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.

Dawn Journal: Going Out on a High...Or Maybe a Low

Marc Rayman • July 18, 2018 • 7

Rapidly nearing the end of a unique decade-long interplanetary expedition, Dawn is taking phenomenal pictures of dwarf planet Ceres as it swoops closer to the ground than ever before.

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.

Dawn Journal: Spiralling Down

Propelled by the perfect combination of xenon ions, hydrazine rocket propellant and adrenaline, Dawn is on the verge of its most ambitious exploits yet.

Hayabusa2: Ryugu takes shape

Emily Lakdawalla • June 14, 2018

Hayabusa2 is now less than 1000 kilometers away from Ryugu, and the tiny asteroid is beginning to betray its shape.

Hayabusa2's Approach phase has begun with a new photo of Ryugu!

Emily Lakdawalla • June 07, 2018 • 1

On June 3, Hayabusa2 ended use of its ion engines, for now, and is coasting the remaining distance toward Ryugu. It's using an optical navigation camera to image the asteroid's position against a field of background stars to help it navigate.
