Crewed Mission to Mars May Be Exposed to Unsafe Levels of Radiation, Study Warns_我的网站

一 | While scientists and science fiction authors alike have long dreamed of sending crewed missions to Mars, a new study suggests these plans may hit a snag – a big one.,The authors of a yet to be peer-reviewed study argue that the participants of such a mission to Mars would end up being exposed to radiation – namely, to “energetic charged particles from Galactic and Solar origin” – both while in transit and while on the planet itself, with the “thin spacecraft shield” and “rarefied Martian atmosphere” offering little in the way of protection.,The research team attempted to gauge the impact of a simulated 1,000-day mission to Mars on various organs of the human body, and concluded that astronauts may be exposed to radiation doses above one Sievert, which is over the safe limit set by most space agencies, New Scientist points out.,“We suggest mitigation strategies such as improved ways of shielding and dietary supplements, and make recommendations for the safety of astronauts in future crewed missions to Mars,” the team wrote in the abstract of their work available on the arXiv preprint server.,Ideas about how astronauts may be protected from radiation during a mission to Mars have already been proposed, such as the concept of a radiation shield comprised of a fungus found growing at the Chernobyl Nuclear Power Plant.,Last year, one architecture studio even unveiled a project for a self-sufficient and sustainable city that would be built on the red planet itself.。

二 | 此役张安达前两局以2:0领先,第三局亨德利扳回一局,但随后,张安达分别以78:0和75:0连续两局零封对手,以大比分4:1报了12年前的一箭之仇。在不久前的欧洲大师赛资格赛中,亨德利以大比分0:5完败于马克·乔伊斯,昔日世界台球领域的超级巨星已无当年之勇。

三 | 在资格赛首日其它几场赛事中,中国选手徐思、陈子凡、赵剑波、李行悉数获胜,挺进正赛。英国公开赛资格赛第二日,又将迎来4名中国选手,其中最引人注目的是奉献赛季首秀的丁俊晖,他的对手是子承父业的“95后”英国小将小莱恩斯。此外,另一位“80后”老将田鹏飞、刚在冠军联赛中杀入决赛的鲁宁,以及14岁时成为斯诺克史上最年轻的排名赛八强选手吕昊天,都将在当日登场亮相。(完)
