Update 4-8-2024: Learn how to estimate the performance of launch rockets or other space vehicles through free short courses on analyzing orbital mechanics available on the Mars Society’s forums. These courses cover a wide range of topics beyond basic orbital mechanics and provide valuable tools for estimating rocket engine performance. The author also welcomes participation in the New Mars forums. The content includes articles on various engineering topics, such as rocket ballistics and heat transfer. Controversially, the author discusses the fatal mistakes made by NASA that led to the Challenger disaster in 1986, highlighting the poorly-designed O-ring seal joints and the risky decision to fly the shuttle too cold.
