Japanese billionaire pulls plug on private 'dearMoon' lunar Starship mission

The Japanese billionaire who commissioned SpaceX for a private mission around the moon on a Starship rocket has abruptly canceled the project, citing ongoing uncertainties around when the launch vehicle will be ready to fly.

“I signed the contract in 2018 based on the assumption that dearMoon would launch by the end of 2023,” Yusaku Maezawa, the backer of the project, said on X. “It’s a developmental project so it is what it is, but it is still uncertain as to when Starship can launch.”

The dearMoon mission was first announced in 2018 — back when Starship was known as Big Falcon Rocket — and it was set to be the first Starship launch to fly humans around the moon and back. At that time, the two parties said they were targeting as early as 2023 for the 240,000-mile journey.

Maezawa announced the eight people who would accompany him and the crew on the mission in late 2022, including Everyday Astronaut’s Tim Dodd, South Korean idol TOP and music producer Steve Aoki. At that point, the publicly stated schedule on the dearMoon website still held to the 2023 timeline; however, four years on from the project’s announcement, it was becoming very obvious that the target launch date was infeasible, given that Starship had, at that time, not yet performed even a single orbital test flight. The project was delayed indefinitely last November.

The cancellation seems to have come as a surprise to at least some of the crew members. “Had I known this could have ended within a year and a half of it being publicly announced, I would’ve never agreed to it,” Dodd said. “We had no prior knowledge of this possibility. I voiced my opinions, even before the announcement, that it was improbable for dearMoon to happen in the next few years.”

Irish photographer Rhiannon Adam, also selected for the mission, was more cutting: “As someone with a critical brain, much of this doesn’t make sense, particularly with regard to timeline. I never believed we were going in 2023, or 2024,” she said.

Reporting at the time suggested that SpaceX was pursuing space tourism as a way to fund the development of the massive, hugely complex rocket. While neither SpaceX nor Maezawa have ever disclosed the likely considerable down payment amount for the flight, Musk said during an event announcing the mission that it was “a non-trivial amount that will have a material impact” on the rocket’s development costs.

But SpaceX’s business has considerably changed since 2018: The company has hit a number of impressive milestones, including certifying and flying its crewed Dragon spacecraft for astronauts, bringing its Starlink satellite internet constellation online, and upping the Falcon rocket launch cadence to nearly 100 per year in 2023. (The company is on track to beat its own record this year.)

The company also scored a landmark contract from NASA to use a version of Starship as a lunar lander for the agency’s Artemis program, and this no doubt considerably shifted SpaceX’s priorities moving forward. Space tourism had to take a backseat to the interests of their largest single customer.

SpaceX’s valuation has steadily climbed, and investor appetite for SpaceX stock seems nearly insatiable. At the end of 2018, the company was valued at $30.5 billion; as of last month, it was reportedly considering a tender offer that could value the company at roughly $200 billion. Meanwhile, space research and news organization Payload Research estimated that SpaceX likely doubled its revenue in 2023 versus the previous year to $8.7 billion.

It seems that Maezawa’s fortune has shifted as well. According to Forbes, his net worth is now $1.4 billion, which is just half as much as it was when dearMoon was announced. Maezawa also scratched his space itch in 2021, when he flew in a Russian Soyuz capsule on a 12-day trip to the International Space Station with the private spaceflight company Space Adventures.

  • Astronauts stuck aboard ISS as Starliner issues delay return

    STORY: Problems with Boeing’s Starliner capsule have upended the original plans for the return of two astronauts to Earth, leaving them aboard the International Space Station as teams look at last-minute fixes. :: June 5, 2024Since its liftoff on June 5 the capsule has had five helium leaks, five maneuvering thrusters go dead and a propellant valve fail to close completely.The current problems center on Starliner’s expendable propulsion system, which is needed to back away from the ISS and position it to dive through Earth’s atmosphere. Starliner can stay docked at the ISS for up to 45 days, according to comments by NASA’s commercial crew manager Steve Stich. He said recent test-firings of the thrusters gave mission teams confidence in a safe return, though tests and reviews are ongoing. A source who spoke on the condition of anonymity said internally, NASA’s latest targeted return date is July 6. That would mean the mission, originally planned for eight days, would instead last a month. Even with the propulsion issues NASA has said Starliner would still be capable of returning the astronauts to Earth if absolutely necessary – that is, if the capsule must serve as an escape pod.If Starliner is deemed incapable of safely returning Barry "Butch" Wilmore and Sunita "Suni" Williams, one option would be sending them home aboard SpaceX's Crew Dragon.NASA and Boeing officials, as well as engineers familiar with the program, told Reuters nothing about Starliner’s current problems indicates that this would be needed.This is Starliner's first mission to orbit carrying astronauts - the final test needed before NASA can certify it as the U.S. space agency's second ride to the ISS.

  • The battle against Guatemala's 'garbage island'

    STORY: This island in Guatemala is made of garbage.There are plastic bottles, tires, sofas — even human remains have been found here.Local residents are worried about it.They fish in Lake Amatitlan, and making a living from it.Tourism boat driver Celestino de la Cruz says he remembers when the lake was crystal clear.Now it's more of a greenish hue.“I don’t know why the lake has deteriorated, it’s a shame to see it,” he says.:: FilePart of the problem, experts say, is industrialization in Guatemala City’s metropolitan area.Rivers carry contaminated water to the lake, which leads to excess nitrogen and propels the growth of a toxic blue-green algae.There have been laws since 2006 seeking to control nitrogen levels in the lake.And surrounding municipalities got funding for water treatment plants - but those resources were re-allocated.The agency for sustainable management of the lake says it’s removing about 100 trucks of trash a day - even during the heavy rains of the winter season.They placed a retention barrier on the lake’s surface that's more than a mile long."We all have the intention to save the lake. It is our hope that one day we will be able to save it,” says trash extraction manager Yuri Geovani.He says without those efforts, the lake would probably be a swamp by now.The agency says over 190,000 cubic feet of trash has been scooped up this year alone.That’s more than two Olympic-sized swimming pools.

  • How a new synthetic skin could help people with eczema

    STORY: This is a lab-grown - synthetic - INFECTED - skin sample.Researchers at Sheffield Hallam University say it could be key to helping people with eczema.“What we're doing is we're making an inflamed skin model and looking at the differences between normal skin and inflamed skin and how bacteria have different relationships with inflamed skin compared to normal skin."Though synthetic skin isn't new - they say this is the first that truly represents skin problems people suffer from.“We’re growing artificial skin in the lab, and we are making an inflamed model of the skin that's representative of atopic dermatitis."Amy Grayson is a post-doctoral researcher at Sheffield Hallam University."And then what we do is we put healthy skin bacteria on the models to make a more representative model because previous models in the past have only used inflamed skin, but they haven't factored in the fact that the skin microbiome has an effect on how the skin grows."The school’s commercial research unit is collaborating with US consumer goods giant Colgate Palmolive.Their goal is to perfect an artificial skin that not only simulates the full thickness of human skin but also accurately emulates its microbiome, including bacteria, fungi, and viruses.It would have important implications for the skincare industry - 20 years after the European Union banned animal testing for cosmetic purposes.The technique relies on mass spectrometry machines developed by Waters Corporation, which can identify molecules by their weight.With it - cosmetic and pharmaceutical companies would be able to test products as if they're being applied to natural human skin.Jim Langridge is the director of Health Sciences at Waters Corporation.“The technology that we develop here at Waters allows researchers to probe the layers of artificial skin so they can determine very precisely the penetration of different drugs and different molecules into those artificial skin sections. So they can determine the different layers and they can also determine how far that drug has penetrated into those layers using our unique technology.”Eczema is a complex, recurring, inflammatory skin condition affecting more than 200 million people worldwide.The condition can be hard to manage.Sufferers often struggle to identify what triggers it to flare up – and how to treat it once it does."For too long it's been trial and error for a lot of people."Andrew Proctor is the chief executive of the National Eczema Society."But where you've got something like this, a novel research approach, it means that there's an opportunity of understanding better what works and why it works and so the opportunity to help people manage their eczema more effectively is just really exciting."
