火星东半球被认为蕴含丰富的冰
#火星

日本高知大学等团队利用地球永冻层的地形数据,得出结论称火星东半球地下有丰富的冰。现在火星是平均气温零度以下极度寒冷和干燥的环境。约 40 亿年前温暖湿润气候时的海水有一部分在地下以冰的形式保留下来。载人航天探测中,水是人类维持生命不可或缺的物质,氢可以用作燃料。如果能在火星上获得,就能为有限的物资运输腾出运力。在 NASA 绕火星卫星拍摄的高清图像中,该团队在实际可以探测的区域内观察了约 4800 张照片,对冰缘地貌的分布进行了调查。结果发现,以东半球为主的3个区域内,多种冰缘地貌密集分布,由此得知地下可能存在大量的冰。3个密集区域与气候模型所需的大量积雪覆盖区相吻合。如果这些冰位于相对较浅可以挖掘的范围,那么着陆时或许可以利用。另一方面,西半球几乎没有冰缘地形。

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.

Telegram hopes to raise $1bn with a convertible bond private placement

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
