From a distance of about 700km, Ryugu's rotation was observed.
Ryugu has been photographed at a distance of 700km in a series of images that show the asteroid rotating.
Ryugu seen from a distance of 920km
Ryugu has now been photographed from a distance of about 920km. The shape of the asteroid gradually appearing.
Ryugu seen from a distance of 1500km
Ryugu has been photographed from a distance of about 1500km. The shape still cannot be seen but the asteroid is very bright.
We have carried out the second optical navigation trajectory correction manoeuvre (TCM02)
On June 11, 2018 at around09:30 - 10:40 JST, the thrusters were fired several times to give an acceleration of 13 cm/s (x-direction), 1 cm/s (-y-direction), 26 cm/s (z-direction). The distance from the spacecraft to the asteroid during the manoeuvre was about 1320km and their relative speed after TCM02 was about 2.1m/s. Until now, Hayabusa2 was approaching Ryugu from the side. But with TCM02, the asteroid is now directly in front of the spacecraft, along the direction of travel.
LIDAR turned on for the first time in two years
The laser altimeter (LIDAR) onboard Hayabusa2 has been turned on for the first time in two years and is functioning well.
Ryugu seen from a distance of 2600km
Optical navigation has begun, using the Optical Navigation Camera. An image of Ryugu taken with the Optical Navigation Camera has been released. (June 07, 2018)
Completion of forward cruise ion engine operation
Ion engine operation to the asteroid is now over. From now on, we enter the final approach phase to asteroid Ryugu. (June 04, 2018)
Hayabusa2's Star Tracker has successfully imaged Ryugu!
The Star Tracker onboard Hayabusa2 has successfully imaged asteroid Ryugu. This data will be used during optical navigation. (May 15, 2018)
"Hayabusa2 NOW" is open!
Communication with Hayabusa2 is via radio waves that are transmitted and received by large antenna at ground stations on Earth. Our website “Haya2NOW” shows these communications in real time. (May 15, 2018)
Hayabusa2 Provisional Mission Schedule
Hayabusa2 mission schedule: provisional version (as of February 21, 2018). (May 07, 2018)
What kind of asteroid is Ryugu？
Hayabusa2 is rapidly approaching Ryugu, so what kind of asteroid is this space rock? Let's take a tour of what we know so far.（Makoto Yoshikawa：2018.04.04）
Hayabusa2 has detected Ryugu!
Hayabusa2 has detected Ryugu! On February 26, 2018, asteroid Ryugu was imaged by the ONC-T (Optical Navigation Camera - Telescopic).
What will asteroid Ryugu look like? We are looking for host organisations for a space art contest!
Between June and July 2018, the spacecraft will reach asteroid Ryugu. We invite science museums, planetariums, public observatories and other centres with space-related activities to become contest "nodes" and help us gather the most imaginative artwork from around the world.
Asteroid Ryugu was observed by VLT successfully
Asteroid Ryugu was observed by the 8.2m telescope of the Very Large Telescope (VLT) of the European Southern Observatory (ESO, Chile) during the night between 11 and 12 July, 2016, and the lightcurve and spectral data were obtained.
Downlink Test Using Ka-band
Today (June 29, 2016), we made a downlink test using Ka-band,and the result was successful. The antenna of DSS26 in Goldstone, DSN (Deep Space Network) of NASA was used and the calibration for the ground station was done today.
We made the first test of Ka-band in the beginning of January 2015, and the test of today was the second time. The distance between the Earth and the spacecraft is about 50 million km, which is about four times larger than the distance at the first test. We are using the X-band (8 GHz) for the daily operation, and we will use the Ka-band (32 GHx) when the spacecraft arrives at Asteroid Ryugu and send the data of Ryugu to us.

Photographing the Earth just before Hayabusa2's swing-by : Complete version
This is a complete version of the image that we showed on December 3.
The Earth’s southern hemisphere taken by TIR (Thermal Infrared Imager) on Hayabsua2
On December 4, 2015, the Earth’s southern hemisphere was imaged by TIR (Thermal Infrared Imager) on Hayabusa2, just as the spacecraft left the Earth upon completing its swing-by.
Antarctica and surroundings imaged by HAYABUSA2

Photographing the Earth just before Hayabusa2's swing-by
As the spacecraft approached the Earth on December 3, 2015, Hayabusa2's onboard Wide angle Optical Navigation Camera (ONC-W2) snapped a few photographs of our planet.
The orbit for Hayabusa2's Earth swing-by has been decided!
Hayabusa2 is set to swing-by the Earth on December 3rd, 2015. Two orbital correction manoeuvres (denoted TCM1 and TCM2) were performed back in November and the precise orbit for the swing-by was fixed.
The Earth and Moon taken by TIR (Thermal Infrared Imager) on Hayabsua2 (II)
On November 26, 2015, the image of the Moon circling the Earth was taken with the TIR (Thermal Infrared Imager) onboard the Hayabsua2 spacecraft as it approached the Earth.
