Hilarious seeing all he space 'tards trying to convince us that sending Artemis to a precise location to nearly intersect with the moon's orbital path is some sort of highly advanced futuristic breakthrough.
The math to achieve this is actually over FOUR HUNDRED YEARS OLD, courtesy of Johannes Kepler who published his First Law of Planetary Motion in 1609.
He also published his Second Law (the Law of Equal Areas) in 1609, which I remember learning in high school. With these two laws, it is relatively simple to calculate trajectories, velocities, gravity effects, planetary motion, etc.
Isaac Newton, of course, further developed the mathematical framework to handle all this in the 17th century.
Anyone claiming NASA has achieved some sort of astonishing breakthrough to "slingshot" Artemis around the moon is four centuries outdated. The math to do this predates the founding of the United States of America.
There's nothing new about Artemis other than the new level of hype and propaganda surrounding it.
