A Japanese astronaut on Thursday apologized for data fabrication and alternation in a research project that he oversaw over a decade ago, Xinhua reported.
Furukawa was responsible for an experiment conducted between 2016 and 2017 which aimed to examine how stress accumulates in the human body when ordinary people stay in a confined space for two weeks.
The Japan Aerospace Exploration Agency (JAXA) determined that Furukawa was responsible for supervising the research and on Tuesday issued a disciplinary warning to the astronaut.
Furukawa, the third Japanese person to have completed a long-term mission in space, is scheduled to make his second stay on the International Space Station this year.
Some JAXA executives, including President Hiroshi Yamakawa, were also reprimanded over the case.
