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

A |     (ECNS) -- Tourists visiting Hengdian World Studios in east China’s Zhejiang Province can now step in front of the camera and play the lead in a vertical-format short drama for 218 yuan ($32), as a newly launched filming experience proves popular with young visitors.    The 218-yuan package includes a standard script and filming, but does not cover makeup, styling or admission to the attraction.        A 388-yuan ($58) option includes makeup and styling. More than 20 scripts are available for individual visitors, with wish-fulfillment storylines similar to those commonly seen in popular online short dramas among the most sought-after choices.    For visitors, the experience involves more than simply dressing up for the camera. Participants act out scripted scenes and may have to perform the same shot several times to get it right.    One woman who traveled from Jiangsu Province said playing a short-drama heroine for the first time was a fresh and enjoyable experience, while another visitor noted that even a single shot could sometimes take several attempts.    The experience had been running for less than a week when the operator said it was already receiving five to six groups a day, totaling around 30 to 40 visitors. More than 100 people had taken part by that point.    Related topics on Douyin had attracted more than 1 million views, while some tourists had traveled by plane from other cities specifically to try the experience.     AI is currently used mainly to generate establishing shots and atmospheric visuals, while its wider application in the filming process is still being explored. Wire-assisted stunt filming featured in some online videos is not yet included in the official experience.    (By Helen Mo, intern Yang Hongran)                    。    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.。
