Don't underestimate the importance of this newest moon touchdown.
The first by the US in additional than 50 years, the primary by a personal firm and the primary so near the intriguing south pole.
Many different nations have landed throughout America's absence: Russia, China, India and most lately Japan. The US is a late runner within the new sprint to the moon.
When America was final there it was with the Apollo programme, which employed 500,000 folks and consumed 2.5% of GDP yearly for a decade.
NASA is sending people again, maybe in as little as two years. But this time it must do it cheaper.
That's the place non-public corporations are available in. The newest touchdown was by Texas-based Intuitive Machines, which was paid $118million (£94million) to take a payload of scientific devices.
That's a cut price for NASA, and a problem for the corporate, which has needed to innovate with 3D-printed rocket engines and different expertise to maintain prices down.
Innovation by corporations like Space X and Blue Origin have made it far cheaper to place satellites into near-Earth orbit. And the hope is that non-public corporations can do the identical to open up entry to the moon, shuttling folks and gear to the floor at a practical worth.
The rekindled curiosity within the moon is due to water.

In the completely shadowed craters on the south pole the temperature is as little as minus 230C and there are good indications that water is current in large portions as ice. That's why Odysseus was despatched to the area.
Water would make long-duration human missions doable.
It would supply hydration for astronauts. But break up the H2O molecule and there may be additionally oxygen to breathe and hydrogen to make rocket gasoline.
But not till robotic spacecraft and rovers truly go into the craters will it's clear how a lot there may be, and the way simply it may be collected.
Odysseus will not try this. But critically the spacecraft is testing out the navigational aids that will likely be wanted to securely land on the south pole, a hazardous area of boulders, cliffs and slopes.
That will make future landings much less of a big gamble. Half of all earlier missions have led to failure.
The success of this touchdown will speed up the arrival of extra spacecraft. Several missions are already deliberate this yr.
In the Greek myths Odysseus was the sensible, courageous hero who undertook a difficult journey.
The similar could possibly be stated of Odysseus the spacecraft because it opens a brand new chapter in lunar exploration.
