A Mars suit or Mars space suit is a space suit for EVAs on the planet Mars. Compared to a suit designed for space-walking in the near vacuum of low Earth orbit, Mars suits have a greater focus on actual walking and a need for abrasion resistance. Mars' surface gravity is 37.8% of Earth's, approximately 2.3 times that of the Moon, so weight is a significant concern, but there are fewer thermal demands compared to open space. At the surface the suits would contend with the atmosphere of Mars, which has a pressure of about 0.6 to 1 kilopascal (0.087 to 0.145 psi). On the surface, radiation exposure is a concern, especially solar flare events, which can dramatically increase the amount of radiation over a short time.

  • マーズスーツ(英語: Mars suit)またはマーズスペーススーツ(英語: Mars space suit)は、火星のEVA用の宇宙服。低軌道のほぼ真空での宇宙歩行用に設計されたスーツと比較して、火星のスーツは実際の歩行と耐摩耗性の必要性に重点を置いている。火星の表面重力は地球の37.8%であり、月の約2.3倍であるため、重量は重要な懸念事項であるが、オープンスペースと比較して熱需要は少ない。火星表面では、スーツにはおよそ0.6~1キロパスカル(0.087~0.145psi)の圧力がある火星の大気と競合する。火星の圧力は約0.6 - 1キロパスカル (0.087 - 0.145 psi) 。表面には、放射線被曝、特に太陽フレアの発生が懸念され、短期間に放射線量が劇的に増加する可能性がある。 火星表面での活動の問題は、空気の大部分が二酸化炭素であるため、人間に十分な酸素があることが含まれる。さらに、空気は海面での地球の大気よりもはるかに低い圧力になる。その他の問題には、火星の塵、低温、および放射線が含まれる。 (ja)
