“龙”飞船载业馀太空人升空 开展首次绕极地飞行任务

美国太空探索技术公司的“龙”飞船载四人“私人”宇航团队升空,开启人类首次载人绕地球两极飞行任务。由于此前的载人飞船均未进入过极地轨道飞越地球两极,这次机组人员将以前所未有的方式观察地球。

美国东部时间星期一(3月31日)晚上9时46分许(新加坡时间4月1日早上9时46分许),太空探索技术公司(SpaceX)的“猎鹰9”火箭携“龙”飞船从佛罗里达州肯尼迪航天中心发射升空。火箭将把飞船送入轨道倾角为90度的极地轨道。宇航员将飞越地球两极,从距地面约430公里的高度观察探索两极,并研究太空环境中的人体健康。

新华社引述美国媒体的报道说,执行这次代号“Fram2”任务的团队四名成员分别是来自马耳他的任务指挥官王春、挪威的飞船指挥官扬尼克·米克尔森、德国的任务飞行员拉贝亚·罗格以及澳大利亚的任务专家兼医疗官埃里克·菲利普斯。

这次任务以挪威极地探险船“Fram”命名,为期三至五天。据任务网站介绍,团队将开展22项实验,包括首次在太空拍摄人体X射线图像,首次尝试在太空种植蘑菇等。宇航员还将使用可穿戴设备监测睡眠、压力、激素水平、血糖等健康数据,研究太空飞行及微重力环境对人体健康的影响。

据太空探索技术公司介绍,“龙”飞船搭载四人返回地球时,将溅落在加利福尼亚州海岸附近。这将是太空探索技术公司载人飞船首次在太平洋溅落。

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
