I checked Wikipedia and was shocked to see how many missions have flown to comets and asteroids. And I say that a space buff since the craddle. Kudos to JAXA, they are really good !!!

Japanese spacecraft successfully touches down on an asteroid, grabbing a sample of dust

Around 200 million miles away from Earth, a Japanese spacecraft just grabbed a tiny sample of dirt off the surface of an asteroid — the second time humanity has ever pulled off such a feat. The precious samples are destined to come back to Earth, where they’ll be analyzed by scientists. This scrutiny could tell us a great deal about the chemical makeup of these rocks, as well as what materials were present in the early days of the Solar System.

Well done Hayabusa 2, cannot wait until next year when the sample will return to Earth. Here is another news article about the mission, this time from the BBC,

Asteroid Explorer Hayabusa2’s SCI Put into Operation
April 5, 2019 (JST)
National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)
The National Research and Development Agency Japan Aerospace Exploration Agency (JAXA) separated the SCI (Small Carry-on Impactor) onboard the asteroid explorer Hayabusa2 for deployment to Ryugu and put the SCI into operation.
After the start of the operation, the camera (DCAM3) separated from Hayabusa2 captured an image that shows ejection from Ryugu’s surface, which implies that the SCI had functioned as planned.
Hayabusa2 is operating normally. We will be providing further information once we have confirmed whether a crater has been created on Ryugu.

This image captured by the camera separated from Hayabusa2 (DCAM3) shows ejection from Ryugu’s surface, which was caused by the collision of the SCI against Ryugu.

Image taken at 11:36 a.m., April 5, 2019 (Indicated by the camera, Japan time)

2nd touchdown image bulletin





Today (July 11), the Hayabusa2 spacecraft performed a 2nd touchdown on the surface of asteroid Ryugu. The touchdown occurred at 10:06 JST at the onboard time and was successful. Below we show images taken before and after the touchdown. As this is a quick bulletin, more detailed information will be given in the future.





■ Images taken with the Optical Navigation Camera – Wide angle (ONC-W1)


Immediately after touchdown, we captured images with the ONC-W1. Here are two bulletin images from this camera.

fig2 : This image was taken on July 11 2019 at 10:08:53 JST (onboard time) with the ONC-W1.

■ Images from the Small Monitor Camera (CAM-H)


CAM-H operated before and after touchdown, capturing images 4 seconds before touchdown, the moment of touchdown and 4 seconds after touchdown. (CAM-H is the camera that was developed and installed on Hayabusa2 through public donations. The field of view is downwards beside the sampler horn.)

fig4 : The moment of touchdown captured with CAM-H(image credit:JAXA).


fig5 : Image taken 4 seconds after touchdown with CAM-H (image credit: JAXA).





Cooperation: Kimura lab., Tokyo University of Science


(The technology for CAM-H is the result of previous collaborative research between JAXA and the Tokyo University of Science.)

Sample collection from asteroid (162173) Ryugu by Hayabusa2: Implications for surface evolution

Abstract
The near-Earth asteroid (162173) Ryugu is thought to be a primitive carbonaceous object that contains hydrated minerals and organic molecules. We report sample collection from Ryugu’s surface by the Hayabusa2 spacecraft on 21 February 2019. Touchdown images and global observations of surface colors are used to investigate the stratigraphy of the surface around the sample location and across Ryugu. Latitudinal color variations suggest the reddening of exposed surface material by solar heating and/or space weathering. Immediately after touchdown, Hayabusa2’s thrusters disturbed dark, fine grains that originate from the redder materials. The stratigraphic relationship between identified craters and the redder material indicates that surface reddening occurred over a short period of time. We suggest that Ryugu previously experienced an orbital excursion near the Sun.

Good news for Hayabusa2, let’s hope JAXA extends the mission to allow study of the second asteroid, though it will be down to how much fuel Hayabusa2 has onboard for the thrusters, and how far away the second asteroid is distance wise.

The Hayabusa2 Re-entry Capsule Approved to Land in Australia
August 19, 2020 (JST)

National Research & Development Agency
Japan Aerospace Exploration Agency (JAXA)

On August 10, 2020, JAXA was informed that the Authorisation of Return of Overseas-Launched Space Object (AROLSO) for the re-entry capsule from Hayabusa2 was issued by the Australian Government. The date of the issuance is August 6, 2020.

The Hayabusa2 re-entry capsule will return to Earth in South Australia on December 6, 2020 (Japan Time and Australian Time). The landing site will be the Woomera Prohibited Area. The issuance of the AROLSO gave a major step forward for the capsule recovery.

We will continue careful operation for return of Hayabusa2 and recovery of the capsule, and the operation status will be announced in a timely manner.

Comment from JAXA President, Hiroshi Yamakawa
The approval to carry out the re-entry and recovery operations of the Hayabusa2 return sample capsule is a significant milestone. We would like to express our sincere gratitude for the support of the Australian Government as well as multiple organizations in Australia for their cooperation.
We will continue to prepare for the successful mission in December 2020 in close cooperation with the Australian Government.
