任务简介

Fram2 是世界上首次前往极地轨道的载人航天任务。该任务以挪威极地研究船 Fram 命名,龙飞船将从佛罗里达发射进入 90° 圆形轨道,成为首个从近地轨道飞越地球极地地区的人类航天飞行。龙飞船上将安装一个穹顶舱,以便在 425–450 公里的高度进行地球观测。 在为期 3 至 5 天的任务中,机组人员将研究绿色碎片和淡紫色连续发射带,这些现象与 STEVE(强热发射速度增强)现象类似,后者持续在地球大气层以上约 400–500 公里的高度被观测到。此外,机组人员还将与 SpaceX 合作开展一系列研究,以更好地了解太空飞行对人体的影响,包括在太空中拍摄首张人类 X 射线图像、即时培训工具以及研究太空飞行对行为健康的影响。 王春(Chun Wang),一位企业家和探险家,共同创立了 f2pool 和 stakefish,担任本次任务指挥官。飞行器指挥官将由电影导演兼摄影师 Jannicke Mikkelsen 担任。飞行器驾驶员将是专业极地探险家和向导 Eric Philips,他曾完成前往北极和南极的滑雪探险。最后一名机组成员是任务专家 Rabea Rogge,一位来自柏林的机器人研究员,目前在挪威攻读博士学位。

SpaceXSpaceXfram2: First Human Spaceflight To Earth’s Polar Regions

Fram2 is the world’s first astronaut mission to polar orbit. Named after the Norwegian polar research ship Fram, the Crew Dragon spacecraft will launch into a 90° circular orbit from Florida, making it the first human spaceflight to fly over Earth’s polar regions from low-Earth orbit. A cupola will be installed on the Dragon spacecraft to allow for Earth observation from at an altitude of 425 – 450 km. During the 3-to-5-day mission, the crew will study green fragments and mauve ribbons of continuous emissions comparable to the phenomenon known as STEVE (Strong Thermal Emission Velocity Enhancement), persistently measured at an altitude of approximately 400 - 500 km above Earth’s atmosphere, among other studies. The crew will also work with SpaceX to conduct a variety of research to better understand the effects of spaceflight on the human body, which includes capturing the first human x-ray images in space, Just-in-Time training tools, and studying the effects of spaceflight on behavioural health. Chun Wang, an entrepreneur and explorer who co-founded f2pool and stakefish, serves as the mission commander. The vehicle commander will be Jannicke Mikkelsen, a film director, and cinematographer. The vehicle pilot will be Eric Philips, a professional polar adventurer and guide who has completed ski expeditions to the North and South Poles. The final crew member will be mission specialist Rabea Rogge, a robotics researcher from Berlin, currently pursuing her PhD in Norway.
