Get These Rich People Off the Moon

Other than allowing billionaires and private companies to benefit from taxpayer-funded pipe dreams and advertising, the value of going to the moon for all mankind is not at all clear.

The US military has also expressed an interest in renting Starships for their Space Force cargo and troops — delivering war to poor countries anywhere in the world within one hour.

Texas start-up Intuitive Machines has achieved the first moon landing by a private firm. It’s dumping rich people’s detritus on the lunar surface — a grim sign of how the superrich plan to plant their flag beyond our own planet.

Amid tears of joy at their Houston control room, the Texas start-up Intuitive Machines successfully landed on the moon. Their uncrewed lander, known as Odysseus, hitched a ride on a SpaceX rocket last week, touching down near the moon’s south pole on Thursday. After many failed attempts by various private outfits, Intuitive Machines is the first private company to plant a free-market flag on the moon

  In January, a different US private venture crashed back to Earth. Astrobotic’s Peregrine lander had been supposed to dispose of at least seventy dead rich people (and one rich dog) on the lunar surface.

Spending billions of dollars dumping odd things in space has become a tradition among the lunar classes. Elon Musk famously sent a Tesla Roadster as the dummy payload for the 2018 Falcon Heavy test flight. Driven by a mannequin in a spacesuit dubbed “Starman,” the car is now an enduring satellite of the sun. You can track him, if you like.

The Japanese isotonic drinks company Pocari Sweat has been trying to leave a can of pop on the moon since 2014. It finally crashed with Astrobotic’s failed $100 million lander. The Japanese still plan to send a hydrogen-powered Toyota “Lunar Cruiser” up there, despite a few explosive setbacks.

Toxic Effects

Other than allowing billionaires and private companies to benefit from taxpayer-funded pipe dreams and advertising, the value of going to the moon for all mankind is not at all clear. British astronaut Tim Peake suggests the microgravity up there might one day enable exotic treatments for all sorts of diseases, albeit expensive treatments for those who can afford them. Aside from body parts, fizzy pop, and “art,” the squillion-dollar landers are packed full of instruments designed for exploring the unknown, before anyone else gets their mitts on it.

So called “NewSpace” companies are on the prowl for profitable rare earth metals, helium-3, and water. Just like the spice of Arrakis, helium-3 is being pitched as “the most precious resource in the universe.” At least it might be if someone invents a use for it. Getting large quantities of water to space is pricey. A stable reservoir will keep plebs alive while they mine for spice. And both hydrogen and oxygen can make the rocket fuel needed to search for shiny things further afield.

It all sounds very exciting. But realizing these fantasies has costs for the rest of us. According to Atrium, a big insurer for rocket-makers, early space-faring outfits should typically expect 30 percent of their launches to end in catastrophic failure. When two separate SpaceX Starship launches in Texas went south last year, toxic particulates rained down on people’s homes. Debris broke windows and caused fires that burned across Boca Chica Park, home to endangered birds and ocelot cats.

“We never gave our consent,” said one indigenous Carrizo-Comecrudo representative at a SpaceX protest in South Texas. “Yet they [SpaceX] are moving forward. It’s colonial genocide of native people and native lands.” Bekah Hinojosa of the Texas environmental group Another Gulf Is Possible claims environmental deregulation, tax breaks, and subsidies have been used by the Texas state government to lure SpaceX in. Meanwhile local indigenous communities who rely on Boca Chica’s fish to feed their families feel their customary land is being sacrificed.

For the Navajo people, the costly blunders are no bad thing. The Navajo hold the moon to be sacred, and consider fly-tipping and mining there an act of profound desecration. According to the Navajo Nation’s president Dr Buu Nygren, “The sacredness of the Moon is deeply embedded in the spirituality and heritage of many Indigenous cultures, including our own.”

Wars on Our Home Planet

Yet, despite the mess they’re making, SpaceX plans on going bigger and bigger.

SpaceX will soon be moving its monster Starship boosters from Boca Chica to the much larger Kennedy Space Center in Florida. Like the Falcon 9, SpaceX’s Starship is designed as a workhorse for frequent, repeated flights. Instead of only a couple of launches per year, Kennedy will start to resemble an airport. The same powerful and destructive super heavy-lift rockets that devastated Boca Chica will be lifting off on a near daily basis from the Florida coast.

The US military has also expressed an interest in renting Starships for their Space Force cargo and troops — delivering war to poor countries anywhere in the world within one hour.

NewSpace is scaling up US geopolitical influence behind a facade of free-market competition. In Indonesia, SpaceX has edged out Beijing to become the country’s satellite launch partner of choice. The partnership was achieved through the personal relationship Musk nurtured with outgoing Indonesian president Joko Widodo. The deal marks a rare instance of a US company making inroads in Indonesia, whose telecommunications sector is dominated by Chinese outfits offering low costs and easy financing. Some see the SpaceX deal as just a sweetener for Musk to build a new Tesla factory somewhere in Indonesia. The electric vehicle-maker has so far signed contracts worth billions for Indonesia’s nickel and other essential materials for the company’s car batteries.

As well as ripping up Indonesia’s pristine forests for luxury car bits, plans to furnish Musk with a new spaceport on the island of Biak, Papua, is fermenting anger among indigenous Warbon peoples. Clearances for the spaceport are reigniting ethnic tensions and military violence. Somewhere between 40 and 150 Papuans protesting the spaceport have been killed by the Indonesian military since the plans were originally unveiled.

Real People Are Gross

Despite the mess it makes on Earth, NewSpace investments are growing in popularity among everyman-for-himself superrich techies.

 For them, dealing with today’s real social and environmental problems tends to involve paying icky taxes and/or remunerating their workers fairly. Meanwhile, finding solutions for potential future problems is far more profitable. For billionaires, “longtermism” packages up this predicament beautifully.

Factoring future populations into decision-making models is just a nice, sustainable thing to do. Longtermism on the other hand, is too much of a good thing. It’s an extreme utilitarian, accelerationist ideology asking us to drastically increase rates of economic growth and technological advancement to ensure humanities’ long-term survivability as a multiplanetary species.

Meanwhile, taxes and government interventions are framed as an impediment to growth and innovation. For these longtermists, someone potentially not being born on Mars in the far distant future is in many ways far worse than someone actually dying of a preventable disease or poverty today. Mars guy is super smart and loaded. Unlike the stinky real person, Mars guy is likely to live a long happy life free of dysentery. He’s white because rich people tend to be that way.

If this all sounds a bit fascist, that’s because it is. According to Oxford philosopher Nick Bostrom, widely considered the founding father of longtermism, “blacks are more stupid than whites,” as he once said on an extropian community message board. “I like that sentence and think it is true.” Bostrom then used an offensive slur beginning with “N.” “It seems that there is a negative correlation in some places between intellectual achievement and fertility,” he argued. “If such selection were to operate over a long period of time, we might evolve into a less brainy but more fertile species.” He later apologized for coming across as “racist.”

Thanks in part to Musk, the cost of space travel has dropped considerably. A seat on a Falcon 9 rocket and an eight-day stay on the International Space Station (ISS) now only costs $82 million. Musk predicts his one-way tickets to Mars will cost somewhere between $500,000 to $1 million, a price at which he thinks “it’s highly likely that there will be a self-sustaining Martian colony.” For the poors, Musk has an indentured labor package where workers take out a loan to pay for their tickets, paying them off later by mining for spice or something.

Life on Earth will end one day (we have somewhere between one and five billion years). But the universe will also end. What then? We could just keep on running through the vacuum of a dying universe. Or, instead of living as slaves obsessing over spice and birth quotas for some odious space baron, we could take a leaf from the Navajo’s book, taking the moon for sacred, and mountains, lakes, and rivers, too. If we treat our planet right, we might just live longer and better.

I’ll admit: I wrote two versions of this article, depending on the fate of the Intuitive Machines lander. In 1969, President Richard Nixon did something similar, just in case everyone died onboard Apollo 11. But when it comes to NewSpace, there’s no need for tears or alternative endings.

Private space missions will only ever serve the billionaires, not us.

If we make no effort to change direction, we will end up where we are heading.”

The new space race Is Causing New Pollution Problems

NY Times, Ed Friedman Tue, 30 Jan 2024

The high-altitude chase started over Cape Canaveral on Feb. 17, 2023, when a SpaceX Falcon 9 rocket launched. Thomas Parent, a NASA research pilot, was flying a WB-57 jet when the rocket ascended past the right wing — leaving him mesmerized before he hit the throttle to accelerate.

For roughly an hour, Mr. Parent dove in and out of the plume in the rocket’s wake while Tony Casey, the sensor equipment operator aboard the jet, monitored its 17 scientific instruments. Researchers hoped to use the data to prove they could catch a rocket’s plume and eventually characterize the environmental effects of a space launch.

In the past few years, the number of rocket launches has spiked as commercial companies — especially SpaceX, founded by Elon Musk — and government agencies have lofted thousands of satellites into low-Earth orbit. And it is only the beginning. Satellites could eventually total one million, requiring an even greater number of space launches that could yield escalating levels of emissions.

SpaceX declined to comment about pollution from rockets and satellites. Representatives for Amazon and Eutelsat OneWeb, two other companies working toward satellite mega-constellations, said they are committed to sustainable operations. But scientists worry that more launches will scatter more pollutants in pristine layers of Earth’s atmosphere. And regulators across the globe, who assess some risks of space launches, do not set rules related to pollution.

Experts say they do not want to limit the booming space economy. But they fear that the steady march of science will move slower than the new space race — meaning we may understand the consequences of pollution from rockets and spacecraft only when it is too late. Already, studies show that the higher reaches of the atmosphere are laced with metals from spacecraft that disintegrate as they fall back to Earth.

“We are changing the system faster than we can understand those changes,” said Aaron Boley, an astronomer at the University of British Columbia and co-director of the Outer Space Institute. “We never really appreciate our ability to affect the environment. And we do this time and time again.”

……………………………… By the time a rocket curves into orbit, it will have dumped in the middle and upper layers of the atmosphere as much as two-thirds of its exhaust, which scientists predict will rain down and collect in the lower layer of the middle atmosphere, the stratosphere.

The stratosphere is home to the ozone layer, which shields us from the sun’s harmful radiation. But it is extremely sensitive: Even the smallest of changes can have enormous effects on it — and the world below.

………………………….Just how rockets will affect that relatively clear top, the stratosphere, remains uncertain. But scientists are concerned that black carbon, or soot, that is released from current rockets will act like a continuous volcanic eruption, a change that could deplete the ozone layer and affect the Earth below.

……………………………………………… A Race Against the Space Race

As space companies set records for launches and satellites deployed, scientists are starting to quantify the potential effects.

In a paper published in 2022, soot from rockets was shown to be nearly 500 times as efficient at heating the atmosphere as soot released from sources like airplanes closer to the surface. It’s the muddy-barrel effect.

“That means that as we start to grow the space industry and launch more rockets, we’re going to start to see that effect magnify very quickly,” said Eloise Marais, an associate professor in physical geography at University College London and an author of the study.

That said, Dr. Maloney’s team did not quantify how much more radiation exposure could occur.

The exact amounts of soot emitted by different rocket engines used around the globe are also poorly understood. Most launched rockets currently use kerosene fuel, which some experts call “dirty” because it emits carbon dioxide, water vapor and soot directly into the atmosphere. But it might not be the predominant fuel of the future. SpaceX’s future rocket Starship, for example, uses a mix of liquid methane and liquid oxygen propellants.

Still, any hydrocarbon fuel produces some amount of soot. And even “green rockets,” propelled by liquid hydrogen, produce water vapor, which is a greenhouse gas at these dry high altitudes.

“You can’t take what’s green in the troposphere and necessarily think of it being green in the upper atmosphere,” Dr. Boley said. “There is no such thing as a totally neutral propellant. They all have different impacts.”

Smithereens of Satellites

What goes up must come down. Once satellites in low-Earth orbit reach the end of their operational lifetimes, they plunge through the atmosphere and disintegrate, leaving a stream of pollutants in their wake. Although scientists do not yet know how this will influence Earth’s environment, Dr. Ross thinks that it will be the most significant impact from spaceflight.

study published in October found that the stratosphere is already littered with metals from re-entering spacecraft. It used the same NASA WB-57 jet that chased the SpaceX rocket plume last year, studying the stratosphere over Alaska and much of the continental U.S.

When the researchers began analyzing the data, they saw particles that didn’t belong. Niobium and hafnium, for example, do not occur naturally but are used in rocket boosters. Yet these metals, along with other distinct elements from spacecraft, were embedded within roughly 10 percent of the most common particles in the stratosphere.

The findings validate earlier theoretical work, and Dr. Boley, who was not involved in the study, argues that the percentage will only increase given that humanity is at the beginning of the new satellite race.

Of course, researchers cannot yet say how these metals will affect the stratosphere.

“That’s a big question that we have to answer moving forward, but we can’t presume that it won’t matter,” Dr. Boley said.

…………………………………..scientists argue, satellite operators and rocket companies need regulations. Few are currently in place.

“Space launch falls into a gray area,” said Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, who has been involved in a working group on this research. “It falls between the cracks of all the regulatory authorities.”

The Montreal Protocol, for instance, is a treaty that successfully set limits on chemicals known to harm the ozone layer. But it does not address rocket emissions or satellites.

In the United States, the Environmental Protection Agency is not responsible for analyzing rocket launches. The Federal Communications Commission licenses large constellations of satellites but does not consider their potential harm to the environment. (The Government Accountability Office called for changes to that F.C.C. policy in 2022, but they have yet to occur.) And the Federal Aviation Administration assesses environmental impacts of rocket launches on the ground, but not in the atmosphere or space.

That could put the stratosphere’s future in the hands of Elon Musk, Jeff Bezos and other private space company executives — which is particularly worrying to Dr. Boley, who says the space industry does not want to slow down.

“Unless it immediately affects their bottom line, they’re simply not interested,” he said. “The environmental impact is an inconvenience.”………  https://www.nytimes.com/2024/01/09/science/astronomy-telescopes-satellites-spacex-starlink.html?action=click&module=RelatedLinks&pgtype=Article
