In light of adverse weather predicted for the launch day, JAXA postponed the launch of Epsilon-3, the third Epsilon launch vehicle which encapsulates NEC Small radar satellite "ASNARO-2" *, from the JAXA Uchinoura Space Center, to no earlier than January 18, 2018.
The Epsilon-3 launch was previously scheduled for January 17, 2018.
The new launch day will be informed once determined.

The H-IIA Launch Vehicle No. 37 with the Global Change Observation Mission - Climate "SHIKISAI" (GCOM-C) and the Super Low Altitude Test Satellite "TSUBAME" (SLATS) onboard lifted off at 10:26:22 a.m. on December 23, 2017 (Japan Standard Time) from the Tanegashima Space Center.
The launch and flight of H-IIA F37 proceeded as planned. So did the separation of SHIKISAI and TSUBAME, which was confirmed respectively at approximately 16 minutes and 13 seconds and 1 hour and 47 minutes 59 seconds after liftoff.

JAXA has updated the launch date of the Epsilon-3 which encapsulates the ASNARO-2. The Epsilon-3 launch, originally scheduled for November 12, 2017, was postponed as its electrical system needed further confirmation. JAXA has identified and taken countermeasures against the factor that delayed the launch. The new launch date will be January 17, 2018.

On November 14, 2017, JAXA invited to the JAXA Tanegashima Space Center (TNSC) the member of the media to see the LE-9 engine assembled for tests. The rain at the site hardly detracted many from around the country to look at the LE-9 model installed in the TNSC firing test chamber.
LE-9 is the liquid rocket engine designed to propel the first stage of H3 Launch Vehicle now under development. From April to July, a series of engine firing testing was conducted on the first LE-9 test engine (Test model#1) primarily to confirm the sequence of activate/deactivate commands and to gain performance data. The second LE-9 test engine (Test model#2) was made public to the press. After the data from the test series is being reviewed and objectives met, the next series of tests on Test model#2 will get readied to start.

The launch schedule of the H-IIA Launch Vehicle No. 37 (H-IIA F37) has been decided to be between 10:26:22 thru 10:48:22 a.m. on December 23 (Sat), 2017 (Japan Standard time). The launch will be performed by Mitsubishi Heavy Industries and JAXA.
H-IIA Launch vehicle No. 37 incorporates JAXA's newly developed outcome to insert SHIKISAI and TSUBAME into different orbit altitude respectively. It will expand opportunities of multiple satellite launch and take full advantage of the capability of H-IIA.

During launch, a rocket makes huge noise equivalent to hundred large passenger jet engines. The acoustic energy can cause damage to its payload as well as the rocket itself. To minimize it, H3 that JAXA is now developing seeks to achieve the world’s quietest launch. As part of the noise reduction program, HARE (H3 Scaled Acoustic Reduction Experiment) was carried out from April to July, at the JAXA Noshiro Rocket Test Center, Akita. The water system is designed to protect the Shuttle and its payloads from any damage that may occur from acoustical energy reflected from the Mobile Launcher Platform (MLP) during launch.
The countermeasures have mainly evolved around simple noise testing and numerical noise analysis. Based on these, installment of the devises has been made at the ground facility including water suppression system and sound absorbing walls. The acoustic tests on a 1:24 scale model of H3 and launch system provided critical data about how the powerful noise generated by the engines and boosters. The data also elucidated the transient pressure rate at the ignition of the solid motor. Analysis of the data will give JAXA deeper understanding of the mechanism of noise generation during liftoff. Application of the HARE data, along with other acoustic data collected at H-IIA and B launches will be used for the design and development of H3 and the ground facility.

The Japan Aerospace Exploration Agency (JAXA) decided to postpone the launch of the third Epsilon Launch Vehicle (Epsilon-3) with the Advanced Small-size Radar Satellite (ASNARO-2) on Board to November 12, 2017, from the Uchinoura Space Center.
JAXA will take extra time to rectify the incompatibility found in the electrical system of the Epsilon-3 in the course of launch campaign at the launch site.

The new launch date will be announced as soon as it is determined.

JAXA announces that the Epsilon 3 launch encapsulating the second Advance Satellite with New System Architecture for Observation (ASNARO-2) is scheduled on November 12, 2017. The launch window is 6 a.m. through 6:35 a.m., in Japan Standard time.
Epsilon launch is not new - the proceeding two were sent up to space. Epsilon 3 has had improved its mechanism for satellite separation. Preparation for the launch is underway.
On the day of the launch, there will be live feed from the JAXA Uchinoura Space Center. The details soon will begin to come out.

Unit tests of the turbopumps, components of the LE-9 engine, are underway at the JAXA Kakuda Space Center. The oxygen and fuel turbopumps are LE-9's essential parts, responsible for supplying liquid oxygen and liquid hydrogen fuel to the engine's main combustion chamber. The liquid hydrogen turbopump delivers 750 liters, or four drum containers of cryogenic liquid hydrogen per second into the LE-9's combustion chamber. The turbopumps mounted on the replicated LE-9 engine undergo a series of testing to ensure their function and performance. At the Kakuda Center, there is a burn pond for disposal of hydrogen gas boil-off. Boiling off unused liquid hydrogen to dissipate produces a towering blaze that can reach fifty meters. Images of LE-9 development is available in the video below with excerpts from the unit testing.

JAXA is inviting all to write notes to cheer on the project members and the mission of Epsilon-3, to be launched this fiscal year.
The project members of the past series of Epsilon launches have drawn strength from the similar campaigns.
The notes sent to JAXA will be printed as part of the decal (sticker) attached to the body of the launch vehicle. JAXA appreciates the positive participation by many.

Application Deadline: 5 pm (JST), August 7, 2017
*The deadline has been changed.

JAXA tested LE-5B-3, the liquid rocket engine designed to propel the second stage of H3 Launch Vehicle now under development. LE-5B-3 enhances the LE-5B-2 engine that likewise boosts the second stage of H-IIA and H-IIB. LE-5B-2 has earned the time-tested record of reliability after scores of successful H-II launches. Improvements are being made to lower the cost of LE-5B-3, without compensating the dynamics to blast off H3, a larger rocket and to sustain its flight.

Following the design improvements for affordability and performance which reached the desired level in August 2016, JAXA successfully conducted the test of the liquid hydrogen turbopump in December 2016 through January 2017. The liquid hydrogen turbopump -- equivalent of the heart of a human body -- draws in the propellants into the engine thrust chamber.

Since March 2017, the first engine with the hydrogen turbopump, assembled for certification was completed, kicking off its preliminary firing testing. The test is proceeding on schedule. By September 2017, test results will expectedly prove the soundness of the basic design improvements.

SRB-3 is an auxiliary rocket, also now under development as solid rocket booster to be attached to the base of the H3 rocket. Strap-on solid rocket boosters derived from SRB-3 reinforce H3’s launch capabilities. Varied configuration – zero, two or four booster(s), depending on the desired thrust – gives the launch vehicle a higher degree of flexibility, one of its strengths. JAXA pursuits cost reduction by use of the technology that produced SRB-A, H-II rocket’s first stage engine, and simplification of the attachment methods. The SRB-3 rocket motor, almost the same size as SRB-A’s, is also configured for the first stage of the Epsilon launch vehicle.

Based on the design review, since April 2017, JAXA has started testing motor strength using the full-scale motor case. SRB-3 is subject to a series of tests, including ground firing and separation.

Computerized images of JAXA's H3 rocket, to be launched in Japanese fiscal 2020, have been available to the public.
The minute-long animation begins with the image of H3, now under development, punching through clouds up towards the space.
With the development in full swing, JAXA appreciates support by all - we certainly draw strength from it to make the total process successful.

On March 31, in Tanegashima Space Center, LE-9 engine for the new H3 type of launch vehicles was installed on the facility’s firing test stand used for liquid fuel boosters. The test schedule will be available on the website as soon as determined.

Solid particles containing iron (dust particles) act to promote the formation of molecules in interstellar space, and are key to understanding physical and chemical processes there.
Iron contained in dust particles comes in various forms such as metallic iron and iron oxide, each with different properties. Previous studies have suggested that iron is present mainly in forms other than iron oxide, iron carbide, and iron sulfide. To verify the possibility that metallic iron is present, a research team led by Dr. Kimura (Hokkaido University) performed in situ observations of gaseous iron cooling in a microgravity environment, and investigated the ease of iron aggregation (the efficiency at which metallic iron forms).
The experimental results showed that, unlike in the results of ground experiments, it was difficult for iron atoms to aggregate. In other words, it is difficult for metallic iron to form in outer space.
The team speculates that iron in dust particles is not a metal, but rather contained as a compound, or adhered to other particles as an impurity.
The results of this research were published in the online journal Science Advances of the American Association for the Advancement of Science on 21 January 2017.

At 8:33 a.m., (Japan Standard Time) January 15, 2017, SS-520 No. 4, JAXA's sounding rocket launched from the Uchinoura Space Center.

JAXA launched the sounding rocket S-520-28 at 4:00:00 p.m. on December 17, 2012 (Japan Standard Time) from the Uchinoura Space Center. The launch aims at conducting a homogeneous nucleation experiment* using the microgravity environment. The vertical angle at the launch was 76 degrees and the experiment went smoothly as planned. The flight and operation of the onboard equipment went well, and, at 10 seconds after liftoff, the nucleation experiment with calcium carbonate started, then at 100 seconds, the nucleation reproduction test started as planned.
The sounding rocket then reached its maximum altitude of 312 km at 283 seconds after liftoff, then dropped into the south eastern ocean off Uchinoura. The acquired data this time will be analyzed in detail.

*In the homogeneous nucleation experiment, we aimed at observing nucleation, which was the first phase of crystallization, by utilizing the microgravity environment during the first few minutes of flight while the sounding rocket was on a ballistic trajectory, then to understand the physics of nucleation. In addition, the experiment also had a purpose of acquiring basic data for future long-term tests to be held repeatedly at the International Space Station.

The 25-year operation and precious observation data of the Experimental Geodetic Satellite "AJISAI" (EGS) was highly evaluated by the Geodetic Society of Japan, and, on May 23, 2011, the Tsuboi Prize (Group Prize) was awarded to a group led by former space verification team project manager Eiichi Hashimoto. The group consists of JAXA, the National Institute of Information and Communications Technology (NICT), the Japan Coast Guard (JCG), Geospatial Information Authority of Japan (GSI), and Hitotsubashi University. The AJISAI was launched on August 13, 1986, to establish the Japan's geodetic datum. The Tsuboi Prize of the Geodetic Society of Japan (Group Prize) is awarded to a group that has made outstanding contributions to geodetic studies as organizational activities are particularly important for geodetic research.
