Streak and Plume from SpaceX Crew2 Launch

What’s happening in the sky? The pre-dawn sky first seemed relatively serene yesterday morning over Indian Harbor Beach in Florida, USA. But then it lit up with a rocket launch. Just to the north, NASA’s SpaceX Crew-2 Mission blasted into space aboard a powerful Falcon 9 rocket. The featured time-lapse video — compressing 12-minutes into 8-seconds — shows the bright launch plume starting on the far left. The rocket rises into an increasingly thin atmosphere, causing its plume to spread out just as it is lit by the rising Sun. As the Crew-2 capsule disappears over the horizon, the landing plume of the returning first stage of the Falcon 9 descending toward the SpaceX barge in the Atlantic Ocean can be seen. Up in space, the Endeavour crew capsule is expected to dock with the International Space Station (ISS) this morning, delivering four astronauts. The Crew-2 astronauts join Expedition 65 to help conduct, among other tasks, drug tests using tissue chips — small microfluidic chips that simulate human organs — that run rapidly in ISS’s microgravity. via NASA

Wikipedia article of the day is Old Spanish Trail half dollar. Check it out: Article-Link Summary: The Old Spanish Trail half dollar was a commemorative coin struck by the United States Bureau of the Mint in 1935. It was designed by L.Β W. Hoffecker, a coin dealer who had been the moving force behind the effort for a Gadsden Purchase half dollar, vetoed by President Herbert Hoover in 1930, and he sought another commemorative coin that he could control if authorizing legislation was passed. He chose the travels of Spanish officer Álvar NΓΊΓ±ez Cabeza de Vaca in the early 16th century. Though Hoffecker’s hometown of El Paso, Texas, is featured on the coin, Cabeza de Vaca came nowhere near its site. Hoffecker purchased the coins from the Mint at face value and sold them to collectors, ostensibly on behalf of the local museum, but in fact for his personal profit, something he later denied before Congress. His design for the coin, featuring the head of a cow (the English meaning of cabeza de vaca), has brought mixed reviews from numismatic commentators.
