Elon Musk has at all times been locked in on Mars.
The world’s richest man has repeatedly mentioned that he based SpaceX again in 2002 primarily to assist settle the Pink Planet. Certainly, the company’s website locations Mars entrance and heart, explaining why the fourth rock from the solar is the perfect goal for human exploration and enlargement.
However over the weekend, Musk threw us a curveball, saying that SpaceX is now centering its settlement plans on the moon — no less than within the brief time period.
“For these unaware, SpaceX has already shifted focus to constructing a self-growing metropolis on the moon, as we are able to doubtlessly obtain that in lower than 10 years, whereas Mars would take 20+ years,” the billionaire wrote on Sunday afternoon (Feb. 8) via X, the social media platform he purchased in 2022.
“The mission of SpaceX stays the identical: lengthen consciousness and life as we all know it to the stars,” he added. “It’s only doable to journey to Mars when the planets align each 26 months (six month journey time), whereas we are able to launch to the moon each 10 days (2 day journey time). This implies we are able to iterate a lot sooner to finish a moon metropolis than a Mars metropolis.”
Should hinted at this shift final week, in a lengthy update detailing SpaceX’s plans to function a million-strong constellation of data-center satellites in Earth orbit.
The automobile that may launch all of those satellites is Starship, the absolutely reusable megarocket that SpaceX has been growing to realize its off-Earth settlement targets. In that Feb. 2 replace, Musk harassed Starship’s lunar potential.
“Because of developments like in-space propellant switch, Starship will likely be able to touchdown huge quantities of cargo on the moon,” he wrote.
“As soon as there, will probably be doable to ascertain a everlasting presence for scientific and manufacturing pursuits,” Musk added. “Factories on the moon can reap the benefits of lunar assets to fabricate satellites and deploy them additional into house. By utilizing an electromagnetic mass driver and lunar manufacturing, it’s doable to place 500 to 1000 [terawatts]/yr of AI satellites into deep house, meaningfully ascend the Kardashev scale and harness a non-trivial share of the solar’s energy.”
(The Kardashev scale, named after the Soviet scientist who got here up with it in 1964, classifies civilizations based mostly on the quantity of vitality they’ll management. A Kind I civilization can harness all of its residence planet’s energy; a Kind II can exploit everything of its star’s vitality, through a Dyson sphere or different such construction; and a Kind III has its complete galaxy’s output at its fingertips. Humanity has not even made it to Kind I but.)
However the off-Earth data-center facet is a mere “bonus component” of the brand new moon-focused technique, Elon Musk harassed in an X post on Monday (Feb. 9).
“The precedence shift is as a result of I am apprehensive {that a} pure or artifical disaster stops the resupply ships coming from Earth, inflicting the colony to die out,” he wrote. “We are able to make the moon metropolis self-growing in lower than 10 years, however Mars will take 20+ years as a result of 26-month iteration cycle. That’s what issues most.”
And SpaceX hasn’t given up on Mars settlement. In different X posts over the previous few days, Musk has emphasised that the brand new plan simply pushes the timeline again a bit.
“Mars will begin in 5 or 6 years, so will likely be completed in parallel with the moon, however the moon would be the preliminary focus,” he wrote on Monday morning. In one other current publish, he mentioned {that a} crewed Mars flight might occur in 2031.
Whereas the settlement give attention to the moon is new, SpaceX has been working towards a crewed lunar mission for about 5 years now. In April 2021, NASA introduced that it had selected Starship to be the first crewed lander for its Artemis program, which aims to establish a permanent, sustained human presence on and around the moon by 2030 or so.
If all goes according to plan, Starship will deliver astronauts to the lunar surface for the first time on the Artemis 3 mission, which is currently expected to launch in 2028. But that timeline assumes success on Artemis 2, which will launch four people around the moon and back to Earth as soon as next month.
It also assumes that Starship will be ready, which certainly cannot be taken for granted. The giant rocket has flown 11 test flights to date, all of them suborbital, so there are a lot of development boxes left to check.
Starship still needs to ace an orbital mission, for example, and show that it can be refueled off Earth. (Each Starship lunar mission will require multiple “tanker” flights — perhaps 10 or 12 of them — to fill the vehicle with propellant for the long journey to the moon.)
Last fall, then-NASA Acting Administrator Sean Duffy voiced concern with the pace of Starship’s development, announcing that he planned to open SpaceX’s moon-landing contract up to competition from other companies, such as Jeff Bezos’ Blue Origin.
That threat may have died down, given that Duffy no longer leads NASA; billionaire tech entrepreneur Jared Isaacman, who has flown to Earth orbit twice with SpaceX, is now the agency’s chief. But competition is still very much in the air; Blue Origin recently announced that it’s pausing its suborbital space tourism flights for at least two years to work on getting humans to the moon.
