>Swinburne and CSIRO researchers have successfully made iron under Mars-like conditions, opening the door to off-world metal production.

Not trying to be pedantic but really curious, it should be off-earth not off-world, right?

Off-world meaning that the iron production is made by alien not human.

Google defines (citing Oxford Languages) offworld as:

* away from earth or (in science fiction) from a place treated as the native world.

* involving, located in, or coming from a place outside one's native world or planet.

While Wiktionary defines it as:

* (chiefly science fiction) Not on Earth.

* (chiefly science fiction) Away from Earth.

To me that sounds like Mars would qualify
