Initiating the second joint exposed experiment on board "Kibo" with the Republic of Turkey

Last Updated: July 19, 2018

In the evening of May 23, 2018, the second experiment of the collaboration mission between Japan and Turkey (*1) has been initiated using the Experiment Handrail Attachment Mechanism (ExHAM) of the Exposed Facility, an external platform outside the Japanese Experiment Module (JEM) "Kibo" of the International Space Station (ISS).

In this experiment, potential satellite-oriented polymer materials with radiation resistant properties will be exposed to space environment for about a year and have performance evaluation after returned to Earth.

At the start of the experiment, researchers from Istanbul Technical University visited Japan and witnessed the moment with JAXA officials in the Kibo Mission Control Room at JAXA Tsukuba Space Center (TKSC).

Comment by Professor Nilgun Baydogan of Istanbul Technical University witnessing the moment the experiment being initiated

We are honored to have this precious opportunity for experiments using the actual space environment. We expect that the results obtained from this experiment will contribute to the development of communication satellite technology.

Along with the Japan-Turkey collaboration experiment, a Japanese experiment has also been underway for "Assessment of degradation of polymer fiber material device exposed to cosmic rays" proposed by Kyoto Institute of Technology, selected as the first utilization theme for the ExHAM onerous utilization program that started in JFY 2017.

The theme whose experiment was initiated so shortly, only five months after the conclusion of the contract, demonstrates that space experiments have become more accessible.

*1:Cooperation mission between Japan and the Republic of Turkey

The "cooperation on Kibo utilization" is a Japan-Turkey national cooperation. In December 2010, "the cooperation agreement relating a space and aeronautical field" was signed by Minister of Education, Culture, Sports, Science and Technology (MEXT) of Japan, and Minister of State for Space Policy, and Ministry of Transport, Maritime Affairs and Communications (MTMAC) of the Republic of Turkey.

Eventually, Japanese Prime Minister Abe and Turkish President Erdogan promised to deepen the "strategic partnership" between the two countries at the Japan-Turkey Summit Meeting held in October 2015.

Upon the bilateral agreement, on September 8, 2016, JAXA and the Republic of Turkey's MTMAC signed a cooperation agreement related to "Kibo" utilization.

The cooperation agreement stipulates that JAXA will offer Turkey opportunities to deploy a 3U CubeSat and conduct long-term exposure experiments of materials and other subjects (twice).

The first long-term material exposure experiment was initiated in April, 2017 and the second experiment was initiated after samples of the first experiment were replaced with the next. The first experiment samples will be returned to the Earth by the Dragon spacecraft (SpX-15).
