The Space Elevator is one of those ideas that seems to have an endless supply of lives. Originally proposed about a century ago, this concept calls for a tether of supermaterial that connects a station in orbit to Earth’s surface. Our planet’s rotation would keep this tether taught, and a system of “climbers” would transport people and payloads to and from space. The engineering challenges and costs associated with such a structure have always been enormous. But every generation or so, new research comes along that causes engineers and space agencies to reevaluate the concept.

Dmitry Rogozin is no Longer the Head of Roscosmos
According to a recent report by Euronews, the controversial head of Roscosmos (Dmitri Rogozin) has been dismissed from his position.

Since 2018, he has led Russia’s space program and established a reputation for inflammatory statements and anti-Western bluster, especially where Russia’s invasion of Ukraine, U.S., and European sanctions are concerned. His dismissal was part of a reshuffle ordered on Friday, July 15th, by Russian President Vladimir Putin.
