ISS国際宇宙ステーション「きぼう」日本実験棟での空間感覚に関する試論

摘要

国際宇宙ステーション（：International Space Station、以下、ISSと呼ぶ）は、地上約400kmの軌道上を周回する巨大な有人施設である。科学•技術をより一層進歩させ地上社会の発展に資することを目的とし、地球の観測や新薬•新素材の開発支援等を行う。計15ヶ国が参加する国際共同プロジェクトで、日本も「きぼう」日本実験棟（以下、日本実験棟と呼ぶ）の開発などをとおして参加している。1998年から建設がはじまり2011年に完成した。%This paper reports the results of experiments in which two astronauts evaluate the volume and impression of the laboratory room and the storage room in the Japanese Experiment Module "Kibo" of the International Space Station under microgravity, and 29 students evaluate the volume and impression of the two mockup rooms on the ground. The results are as follows.1)The volume of the storage room of ISS was overestimated, or the volume of the laboratory room was underestimated. On the other hand, both the volume of the two mockup rooms were evaluated almost exactly. 2) Both the storage room and the laboratory room of ISS were evaluated as being "spacious", "not oppressive", "calming" and "comfortable". On the other hand, the mockup of the storage room was evaluated as being "not spacious", "oppressive" and "calming", and that of the laboratory room was evaluated as being "spacious", "not oppressive" and "not comfortable".
