Why Rockets Don’t Go Straight Up to Space

The Jolly Leader on Instagram: "A Masterclass in DIY Engineering: The Thai Rocket Festival! 🚀🔥 ​Watch as this massive, homemade circular rocket—known as a Girandola style rocket—takes to the skies during a traditional Rocket Festival. What starts with a thick cloud of smoke quickly turns into a steady, powerful ascent as the rocket spins its way toward the clouds. The rhythmic "huffing" sound of the engines is as mesmerizing as the visual itself! ​Known for being both a spiritual tradition and

Jeffrey Epstein on Instagram: "The operating principle of a liquid hydrogen rocket engine can be divided into several key stages: 1. Storage and supply of fuel and oxidizer: A liquid hydrogen rocket engine uses liquid hydrogen (LH2) as fuel and liquid oxygen (LOX) as an oxidizer. These substances are stored in two separate cryogenic tanks at very low temperatures (hydrogen about -253°C, oxygen about -183°C). Fuel and oxidizer are supplied to the fuel lines using high-pressure pumps. 2. Mixing an
