"By the time #BlueOrigin was created in 📆 2000, #Amazon had already earned him several billion. #SpaceX 🐇 came about two years later when #Musk successfully sold #PayPal for $160 million. The turtle’s pace 🐢 made #NewShepard #BlueOrigin’s only real achievement in 20 years. A #suborbital booster with a cargo-passenger capsule starts vertically and rises to a height of 100km" https://orbitaltoday.com/2022/04/19/blue-origin-vs-spacex-the-hard-race-to-space-leadership

#Artemis :#NASA's "#SLS #rocket 🚀 is #smaller than the #Saturn V. It is also much more #expensive. Adjusted for #inflation, the cost 💰 of one launch of the Saturn V in the 1960s was around $1.5 billion, which is a far cry from the $4 billion required for just one SLS launch." https://www.aerotime.aero/articles/32011-nasas-powerful-and-contraversial-sls-rocket-ready-to-launch
