Although the US’ Moon landings were mostly made famous by the fact that it featured real-life human beings bunny hopping across the lunar surface, they weren’t there just for a refreshing stroll over the lunar regolith in deep vacuum. Starting with an early experimental kit (EASEP) that was part of the Apollo 11 mission, the Apollo 12 through Apollo 17 were provided with the full ALSEP (Apollo Lunar Surface Experiments Package). It’s this latter which is the subject of a video by [Our Own Devices].
Despite the Apollo missions featuring only one actual scientist (Harrison Schmitt, geologist), these Bendix-manufactured ALSEPs were modular, portable laboratories for running experiments on the moon, with each experiment carefully prepared by scientists back on Earth. Powered by a SNAP-27 radioisotope generator (RTG), each ALSEP also featured the same Central Station command module and transceiver. Each Apollo mission starting with 12 carried a new set of experimental modules which the astronauts would set up once on the lunar surface, following the deployment procedure for that particular set of modules.
Although the connection with the ALSEPs was terminated after the funding for the Apollo project was ended by US Congress, their transceivers remained active until they ran out of power, but not before they provided years worth of scientific data on many aspects on the Moon, including its subsurface characteristics and exposure to charged particles from the Sun. These would provide most of our knowledge of our Moon until the recent string of lunar landings by robotic explorers.

Not a hack…
Humans in space is definitely a hack. Why wouldn’t you want to know about the cool stuff they did there?
Once again, the hack is in the comments
Want something to hack, on the moon?, the dust!
Looking at the pictures shows how the dust was one of the biggest issues, fantasticly fine, statickly charged, adrasive, and everywhere in unlimited quantities.The dust is also I believe chemicaly reactive with
water and likely other things bieng brought to the moon.
The dust is bad enough that any long term outpost on the moon will
need some way to keep habitation and any presurised work areas dust free, and sealing locks and moving parts will be difficult.
Mars is different, as there is enough water , atmosphere and gravity to cement a lot of the dust, still a problem, but the moon dust is a huge challenge.
Robots don’t mind the dust.
The Mars insight probe disagrees

There has been some thought on using solar or nuclear to crack the aluminum and oxygen apart in regolith, then recombine them violently as solid fuel boosters. Not the best rocket in the universe, but considering it’s basically free while you’re on the moon… It’s good enough to get a lot of other useful stuff out of the gravity well:

Ok, here’s the ‘hack’ angle…. could alsep been fixed on Apollo 16
On Apollo 16 the holes for the probes were dug by Charles Duke who managed to drill down to 3 m (10 ft) below the surface.[4] The drill on Apollo 16 had been modified to rectify the issues experienced on the prior mission, Apollo 15. The experiment came to an end before it started when John Young tripped over the cable connecting the experiment to the ALSEP central station.[5][4] The cabling was designed to resist tensile strains from being tugged, but it was not designed to resist tearing motions.[1] Repairing was considered but rejected due to it needing several hours of surface time.[4]
