On Sept. 1 (Tue.) and 2 (Wed.), the ion engine of the Hayabusa2 was additionally operated in order to increase the orbit control accuracy for the Earth swing-by.
The additional jet emission was completed as scheduled, and the ion engine was operated for about 12 hours in total.
We will analyze telemetry data (data sent from the explorer to indicate its condition) in detail to confirm the status of the engine during the operation and orbit control before and after the emission.

JAXA is holding a naming proposal campaign to christen the asteroid “1999 JU3″,which the Hayabusa2 is scheduled to visit in June or July 2018. Why don’t you try to become a godparent of the asteroid?
The application period is from 1:30 p.m. on July 22 thru 11:59 p.m. on August 31 (Japan Standard Time.)

August 31, 2015 at 11:59 p.m. (Japan Standard Time). (Extended from 10:00)

The Hayabusa2 has been continuously operating its ion engine for the second time since June 2, and successfully completed its operations at 0:25 a.m. on　June 7 (Japan Standard Time.) The second continuous operation lasted for 102 hours as scheduled.
The Hayabusa2 performed the ion engine continuous operation in preparation for the Earth swing-by planned in December, and the total hours of the first and second operations (409 hours and 102 hours respectively) reached 511 hours.
The ion engine operation may be conducted again if needs arise for subtle orbit change after carefully examining the second operation result.

The Hayabusa2 is stably flying in space. The new fiscal year has just started in Japan, and JAXA is taking a new step　as we became a National Research and Development Agency from the previous independent administrative agency. The Hayabusa2 project is also taking a fresh step with a new team, including handing the baton over to a new project manager. All members of the project are engaged in the mission with a fresh mindset.

The Hayabusa2 is stably flying since its launch and smoothly continuing it interplanetary cruising. I can, therefore, take over the mission at the best condition from my predecessor, former Project Manager Hitoshi Kuninaka, who led the development of the project. With many operation experts joining the new team, we would like to successfully send the Hayabusa2 to the asteroid 1999JU3, and have it come home safely.
The Hayabusa2 mission is challenging an unexplored field. We would like to contribute to enhancing the value of technology, science and space exploration through our accomplishments in traveling through the solar system in this six-year mission.

As the development phase is over, Hayabusa2’s deep space exploration has started.
At the beginning of this fiscal year, a multiple number of our project members including myself were subject to personnel changes. Our team worked well with good team spirit to tackle and overcome various obstacles and difficulties. Therefore, I felt a bit disappointed to see part of the team was shuffled. Having said that, those who remain in the team as well as the leaving members vow to work hard and do our best using our expertise in space projects no matter what department we are assigned to. Your continued support for the Hayabusa2 is very much appreciated.

The Asteroid Explorer “Hayabusa2,” launched on Dec. 3, 2014, completed its initial functional confirmation period of about three months. The explorer was moving to the cruising phase on March 3 while heading to the asteroid “1999 JU3.”
The Hayabusa2 is in good health. It will be under preparatory operation including speed increase by continuous operation of the ion engines for an Earth swing-by scheduled in Nov. or Dec., 2015.

The Hayabusa2, launched on Dec. 3, 2014 (JST), is now undergoing the initial functional confirmation. Basic operations and performance of onboard instruments and ground systems have been tested one by one as of the end of January.
Here are some major examples of what we confirmed.

The explorer is currently in good shape.
We will further confirm the coordinated function of multiple instruments of the Hayabusa2, and plan to move to the cruise operation phase (*2) sometime in March.

*1 The autonomous operation is automatic control of an engine without instructions from the ground.
*2 The mode of full-scale navigation operation toward the asteroid through acceleration and orbit control by ion engine thrust.

JAXA confirmed the completion of a sequence of the important operations for the “Hayabusa2” mission. With this confirmation, the critical operation phase* of the Hayabusa2 was completed.
The explorer is now in a stable condition.

We would like to express our sincere appreciation to all parties and personnel concerned for their support and cooperation with the Hayabusa2 launch and tracking control operations.
In addition, we would also like to ask for your continued cooperation and support for the long-term Hayabusa2 space exploration mission.

The Asteroid Explorer “Hayabusa2” was shown to the media at Sagamihara Campus on August 31, 2014.

The Hayabusa2 is the successor of the Hayabusa, which captured sample particles from an asteroid and returned to the Earth in 2010. By capitalizing on the experience of the Hayabusa, the Hayabusa2 aims at acquiring samples and bringing them back from the C-type asteroid “1999JU3” to elucidate the origin and evolution of the solar system and material for life.

“I am bracing for the new voyage of the Hayabusa2.” said Project Manager Kuninaka.
The Hayabusa2 will be transferred to the Tanegashima Space Center for its launch in this winter after its final check there.

Hayabusa2’s Small Carry-on Impactor (SCI) underwent a test in October, 2013.
The SCI is a device to create an artificial crater of the asteroid 1999JU3, which the Hayabusa 2 will travel toward. By making and observing an artificial crater, we can acquire data not only about the surface but also about the inside of the asteroid. In addition, by sampling near the crater, we can collect inside samples of the asteroid.
Hayabusa2 applies a method to throw a metal projectile against the asteroid with high speed to create an artificial crater. Through the test this time, we confirmed the accelerating part of the projectile while aiming to verify if its speed, configuration, and thrown direction precision met the design when the pyrotechnics, which were comparable to those of actual ones for the flight, were ignited to set off the projectile.
The test results were very impressive as the speed and configuration were almost as designed, and the direction precision was also good as the SCI precisely hit a target that was 100 meters away. We were able to successfully complete the performance confirmation test of the SCI pyrotechnic part.
