Artist Conception of the Hayabusa2 spacecfaft landing on Ryugu
n December of 2014, the Japanese Aerospace Exploration Agency (JAXA) launched the Hayabusa2 mission. As the second spacecraft to bear this name, Hayabusa2 was deployed by JAXA to conduct a sample-return mission with an asteroid. By studying samples of the near-Earth asteroid 162173 Ryugu, scientists hope to shed new light on the history of the early Solar System

Rover-1B shot a 15-frame movie on asteroid Ryugu’s surface. This movie covers a little over an hour, 9:34 a.m. to 10:48 a.m. EDT, on September 22. “Enjoy ‘standing’ on the surface of this asteroid!” the Hayabusa2 team tweeted. Read more:

Earlier this week asteroid Ryugu had a visitor. The Mobile Asteroid Surface Scout (MASCOT) landed on Ryugu on October 3rd after it was successfully deployed from the Japanese Hayabusa2 space probe. The little hopping robot’s visit was brief however, and it stopped functioning on Oct. 4th 2018.

Japan’s Hayabusa2 mission is about to get down to business. After arriving at asteroid Ryugu at the end of June 2018, and dispatching its tiny rovers to the surface, the spacecraft is about to approach the surface of the asteroid and get some samples.

Japan’s Hayabusa2 spacecraft has completed an important part of its mission to asteroid Ryugu. The spacecraft descended to the surface of the asteroid to collect two samples with its sampling horn. We don’t know for sure if samples were successfully collected, but all indications are that the sampling mission went well.
This is an exciting accomplishment for JAXA, and marks their second successful asteroid sampling mission, following the success of the first Hayabusa mission to the asteroid Itokawa.

Japan’s Hayabusa 2 spacecraft is now the first spacecraft to retrieve a subsurface sample from an asteroid. On July 11th,2019 the spacecraft touched down for a second time on asteroid 162173 Ryugu. This time, the probe retrieved a sample from a crater it excavated with its impactor.

DCAM 3 captured this image of the SCI impact on 5 April 2019. The impact debris is a small spray of dust against the black of space, near the top-right limb of the asteroid. Image: JAXA
[PPTD] These images were taken immediately after today’s touchdown (Jul 11, 2019) with the ONC-W1. First photo was taken at 10:06:32 JST (on-board time) and you can see the gravel flying upwards. Second shot was at 10:08:53 where the darker region near the centre is due to touchdown.

On Monday, at 10:37 AM local time (02:37 AM PST; 05:37 Tuesday 09-17-2019 EST) JAXA announced their success on the mission’s official Twitter account. They also posted time-lapse photos of the target markers falling towards the surface, which slowed a slight parabolic arc to their descent. Professor Makoto Yoshikawa, Hayabusa 2’s mission manager at JAXA, also issued a statement about the agency’s success.

Credit: JAXA Like the previous MINERVA-II rover (ROVER-1), ROVER-2 will land on the surface, hop around to relocate, and conduct science operations with its suite of scientific instruments – which include two cameras, a thermometer, and an accelerometer. This represents the final phase of Hayabusa2‘s science campaign at Ryugu – which will end this December, followed by the spacecraft returning to Earth (arriving by December 2020).
Japan’s Hayabusa 2 mission to asteroid Ryugu has reached one of its final milestones, if not its climax. The sample-return spacecraft has launched the Minerva-II2 rover at the asteroid. This is the last of four rovers that Hayabusa 2 is deploying on Ryugu.

Japan’s Hayabusa 2 spacecraft is on its way home.(Novenber 2019) The asteroid-visiting, sample-return mission departed asteroid Ryugu (162173 Ryugu) on Wednesday, beginning its year-long journey back to Earth. And it’s carrying some precious cargo.

In 2014, the Japan Aerospace Exploration Agency (JAXA) dispatched its Hayabusa2 spacecraft to rendezvous with 162173 Ryugu, a Near-Earth Asteroid (NEA) that periodically passes close to Earth. In 2018, this sample-return mission reached Ryugu and spent the next year and a half studying its surface and obtaining samples from its surface and subsurface. By 2020, these samples made it back to Earth, where scientists began analyzing them in the hopes of learning more about the early history of the Solar System and answering key questions about the origins of life.
