Technically the US measurement system is metric since the Mendenhall Order of 1893 reestablished all customary units as conversion factors of metric units. In 1933 the ASA redefined the inch to be exactly 25.4mm, following the lead of the British Standards Institution in 1930 (precision was increasingly important for manufacturing, and the previous value of 25.40005mm had become impractical). The international yard and pound were officially adopted by the US National Bereau of Standards (now NIST) in 1959, the Metric Conversion Act was passed in 1975, and finally EO 12770 (1991) required all agencies of the executive branch to transition to metric units.
So, from one point of view we’ve been transitioning to metric since 1893 and it’s still not done. From another, the inch is just a metric unit as its length is officially defined in millimeters (all customary units are now based on SI units), therefore the conversion is complete.
The Intuitive Machines lander issue was that no one disarmed the safety switch on the laser guidance system. (No, really!) Luckily NASA had a backup system installed that ended up working better anyway.
Not sure if it ended up working better, as it landed with nonzero horizontal velocity. Though I suppose we’ll never know how well the original system would have performed…

They did it once by mixing meters and feets, and crashed the Mars lander.
Edit: looked it up, wasn’t actually meters vs feet, but newton-seconds vs some American eagles per gun unit for force
it’s an orbiter not a lander
It was intended to be an orbiter.
rods from god
Ended up a missile
Peger the term high velocity lander
Hopefully, the transition to metric is soon and I can stop reading this same joke every week.

Pound-seconds, I believe. Good ol’ LM giving imperial numbers to NASA.

It’s guns per eagle, get it right. What would eagles per gun even be?
A gun that shoots eagles, obviously
We don’t shoot eagles in America, we shoot turkeys. Just as Benjamin Franklin intended.

it happened again with the Intuitive Machines lander that landed on the moon last week

Pretty much the hardware version of && false
