i’m not ashamed.
DISCLAIMER: as i have received some complaints and hates from dumb people, this video is only a JOKE intended to sneer at people who talk about the efficiency of a landing without taking the whole figure in mind.
For instance, the Constant altitude landing is the most efficient way to land but it’s poorly precise and implies some realtime math integration, which is not practicable.
When you target a landing site, the most efficient technique is not the best one. That’s why Apollo missions used a Reverse gravity turn to land on the Moon. It’s a good compromise between ease of execution, precision and efficiency.
