“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。

At a time when the Indian stock market is peaking and has rallied immensely compared to global markets, there are companies that have not performed in the last 10 years. These are definitely a minor portion of the market considering there are hundreds of stocks that have turned multibagger since 2020. What went wrong with these stocks? Reasons vary from corporate governance, sectoral weakness, company specific and so on. But the more important question is, are these stocks worth buying?

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
