Perhaps you’ve heard, however Elon Musk is outwardly a Moon fan now. He has traditionally been the final word cheerleader for human missions to Mars, and as not too long ago as final yr, he stated his goal was to go straight to the pink planet and that the Moon was “a distraction.” Now, he has apparently modified his thoughts, asserting that SpaceX has shifted focus to constructing a metropolis on the Moon.
Throughout the house science neighborhood, this information concerning the Moon has largely been met with eye rolls, primarily as a result of so many have change into jaded towards Musk’s overly bold plans and wildly unrealistic time scales.
“It was exhausting for me to take these Mars plans critically,” stated house coverage knowledgeable Wendy Whitman Cobb of the Faculty of Superior Air and House Research. She has stored an eye fixed on SpaceX’s job postings lately and identified that the corporate has proven no real interest in hiring roles associated to Mars applied sciences. This means there has lengthy been a disconnect between the precise work that SpaceX is doing in its improvement of Starship versus the grandiose means that Musk has talked about future colonization plans.

“I’m undecided SpaceX, the corporate, was ever centered on Mars. I believe that was largely [Musk],” she stated.
Even among the many most ardent Mars fans, there’s an acknowledgement that the technical challenges standing between humanity and a crewed Mars mission are important. Constructing habitats, rising meals, defending towards radiation, and different problems with infrastructure and process are important obstacles that should be overcome, to not point out challenges similar to in-space refueling of rockets and launching a rocket from one other planet — which comes with its personal challenges associated to the extraordinarily skinny carbon dioxide environment and the shortage of a launchpad to make use of as a steady base.
These are all doubtlessly solvable points, however they require the event and testing of latest applied sciences, which is able to take years or, extra doubtless, many years. And when you find yourself on the lookout for a testing floor, the Moon — just a few days away from Earth, with evacuation attainable in an emergency — is considerably extra interesting than Mars, the place astronauts can be on their very own for months at a time.
This has been NASA’s method lately below its Moon to Mars program. First, the logic goes, we use the Artemis program to check and observe placing astronauts on a lunar base for a interval of weeks or longer, then we use that data to ship future explorers on longer-term missions to Mars.
“The Moon is probably the most pure place on the earth to me, to begin when it comes to a long-term, sustained presence in deep house,” stated astronomer Paul Byrne of Washington College in St. Louis. It might have been simpler to do that constructing instantly from the Apollo missions within the ’60s and ’70s, when institutional data was nonetheless obtainable, however it might nonetheless be finished: “One of the best time to do it was after Apollo, however the second greatest time to do it’s now.”

There are additionally good scientific causes to go to the Moon, similar to studying concerning the formation of the photo voltaic system. There are even proposals to place telescopes there, making the most of the shortage of environment to permit a lot higher energy from a smaller telescope in comparison with these on Earth.
However probably the most urgent motivations to return people to the Moon are largely geopolitical, with China looking for to develop its human house program and stake out a presence there inside the subsequent decade and the US unwilling to be crushed to the punch.
Equally, SpaceX’s guiding motivation could also be much less philosophical and extra classically capitalist, as the corporate engages in some old school competitors with its rival Blue Origin. Jeff Bezos’ firm is growing its personal lunar lander for NASA and will doubtlessly leapfrog SpaceX to change into a big lunar accomplice for NASA.
“It’s possibly simply primary enterprise rivalry,” Whitman Cobb stated. “That has been the hallmark of Blue Origin versus SpaceX for many years now.” There’s additionally the matter of SpaceX’s looming IPO and the necessity to present traders what a practical plan for earning profits would possibly contain.
Regardless of the motivations of these concerned, and for all of the frustration with Musk’s off-the-cuff method to asserting house coverage, there’s a hope that having him come round to supporting a virtually achievable Moon mission is a constructive step.

“I discover it encouraging, as a result of it’s extra lifelike,” stated Kyler Kuehn, appearing director of Science at Lowell Observatory. “Even when the timescale is possibly nonetheless unrealistic.”
Even now, Musk is claiming that, following Moon missions, SpaceX might be constructing a metropolis on Mars “in about 5 to 7 years,” a hilariously optimistic timeline provided that Starship has not even been confirmed flightworthy but. You would possibly recall Musk beforehand claiming that people can be on Mars by 2022, or 2024, or 2029.
He has additionally mentioned making cities on Mars “self-sustaining,” an much more bold and unrealistic aim for the close to future, in addition to sci-fi concepts like terraforming Mars and constructing spaceports there. It’s not that these grand plans may by no means be realized by humanity, however they definitely gained’t be occurring in any of our lifetimes, and pretending that they’ll allow human life on Mars inside the subsequent few years is delusional at greatest and downright misleading at worst.
In spite of everything, it’s straightforward to make an announcement, however a lot more durable to grapple with the cautious, incremental strategy of technological improvement — particularly when there are human lives at stake. Below these situations, specialists aren’t shocked when house mission timelines regularly slip.
“While you go from advertising and marketing to the precise engineering, that is at all times what was going to occur,” stated Kuehn.
And, he factors out, there’s worth in being upfront concerning the scale of the challenges forward: “If individuals understood that these issues are exhausting and it’s going to take many years — they won’t like to listen to it, however they’d get a greater concept of how this actually works, and in some methods, that may be inspirational. It’s a multi-generation downside: I’m not going to get to go to Mars, however possibly my daughter will.”
Nonetheless, because the gulf between the tech bro advertising and marketing converse and the sluggish, costly, cautious actuality of house exploration widens, “there’s a threat that the general public will get jaded by this, on the time when NASA and different house companies want the general public to get behind them,” stated Byrne.
Because the face of house exploration to a lot of the general public, Musk’s phrases nonetheless carry weight and due to this fact duty: “There comes a degree the place the general public is both going to lose curiosity or simply begin to suppose that this can be a rip-off and it’s not ever going to work.”
