Technological demonstration of protein crystallization at 4℃ (August 16, 2016)

JAXA has conducted protein crystallization (the JAXA PCG experiment) at 20℃ for a long period of time. Meanwhile, new devices to realize the experiment at 4℃ have been organized.

CALET has succeeded in observing electron precipitation (July 6, 2016)

The CALorimetric Electron Telescope (CALET) onboard the Japanese Experiment Module "Kibo" of the International Space Station (ISS) since 2015 has succeeded in observing a tremendous shower of electrons (called "Relativistic Electron Precipitation: REP").

JAXA PCG (fourth session of the second series) begins (May 2, 2016)

The Protein Crystal Growth experiment (JAXA PCG, fourth session of the second series) has begun in the Japanese Experiment Module ("Kibo")

The Philippines' 50-kg-class microsatellite "DIWATA-1" has been received. DIWATA-1 will be released from Kibo this spring. (February 3, 2016)

On January 13, 2016, a 50-kg-class microsatellite called "DIWATA-1" (meaning "fairy" in Filipino) was handed over to JAXA.

The second experiment using the ExHAM now underway (January 19, 2016)

The ExHAM offers the advantage of being able to return samples directly to the cabin after exposure to the space environment, without the need to perform Extravehicular Activities.

Increasingly evident effects of a long-term culture in the space environment on Medaka fish genes (January 18, 2016)

A research group headed by Professor Hiroshi Mitani of Tokyo University and Professor Shuji Terai of Niigata University analyzed the gene expression of medaka cultured on the ISS, with the results being published in PLOS ONE, a U.S. scientific journal.

Japanese and Brazilian CubeSats deployed from Kibo (October 22, 2015)

On September 17, 2015, two CubeSats -- SERPENS developed by the University of Brasilia (UnB) and S-CUBE of the Chiba Institute of Technology -- were successfully deployed from the Japanese Experiment Module ("Kibo").

Protein crystals grown in Kibo have returned to the ground (JAXA PCG experiment) (October 16, 2015)

Samples of the protein crystals for the JAXA PCG experiment launched alongside Astronaut Kimiya Yui aboard the Soyuz TMA-17M spacecraft (43S) on July 23 have completed growth in space and were returned to Earth.

Free-Space PADLES experiment conducted (July 14, 2015)

The first Free-Space PADLES experiment intended to investigate the space radiation dose outside the Japanese Experiment Module ("Kibo") was conducted from June 1-15, 2015.

First experiment using the Exposed Experiment Handrail Attachment Mechanism (ExHAM) started (June 8, 2015)

On May 26, 2015, the first experiment started using JAXA's new experimental device, Experiment Handrail Attachment Mechanism (ExHAM).
