Breaking: PioneerLabs has engineered a microbe able to live on Mars, consuming solely nutrients found on the planet to create building materials. I interviewed Erika Alden DeBenedictis, the CEO, to learn how they did it and what might come next. Much of the interview was about bottlenecks to growing...

@Pioneer__Labs @erika_alden_d I don't understand what it means for the bacteria to be able to "live on Mars", if it didn't have to survive any of the Mars atmospheric conditions. It seems more like "bacteria that can live off a feedstock we expect to be cheap on Mars", no?

@Pioneer__Labs @erika_alden_d Oh she is great at her explanations. Great speaker too. I fully believe and support @pioneer__labs

Mars will be our next planetary home for human civilization. Here are a few things you need to know > Mars formed about 4.5 billion years ago alongside Earth and likely started as a warmer, wetter world before it lost its global magnetic field and dried into the cold desert seen today > Mars is only about half the physical size of Earth, but because it has no oceans, its total dry land area is similar to all of Earth’s continents combined, making it effectively 100% usable “real estate” > Surface gravity on Mars is just 38% of Earth’s, so you could jump roughly three times higher and lift much heavier objects than you could on Earth > New evidence suggests a massive reservoir of liquid water may be trapped 10–20 kilometers beneath the Martian crust, theoretically enough to cover the whole planet in an ocean if it were brought to the surface > The search for alien life has intensified after NASA’s Perseverance rover found rocks with “leopard spot” patterns that may record chemical signatures consistent with ancient microbial life, though the findings are still being tested > Martian weather is extreme: the average temperature is about -81°F (-62°C) and can drop near -225°F in some regions, yet summer days near the equator can briefly reach around 70°F, similar to a mild day on Earth > Colonizing Mars will be difficult because of toxic soil, high radiation, and a very thin atmosphere, but deep underground water and protected subterranean habitats could make long-term human survival scientifically possible > Sunsets on Mars appear blue rather than red because fine dust in the thin atmosphere scatters red light away from the line of sight and lets more blue light pass through > Mars has two small, irregular moons, Phobos and Deimos; Phobos is slowly spiraling inward and is expected to eventually break apart, likely creating a temporary ring system around the planet > The planet hosts some of the most extreme landscapes in the solar system, including Olympus Mons, a giant volcano about three times taller than Mount Everest, and Valles Marineris, a canyon system so huge it makes the Grand Canyon look tiny by comparison > We are still only visitors on Mars, but with every SpaceX Starship mission, we get closer to the day this harsh red desert becomes humanity’s next home H/t: X Freeze

Elon Musk just said the first missions to Mars don’t matter. From the man spending billions to get there. Musk: “The first missions to Mars are not that important. What matters is, can you get sufficient tonnage to Mars such that Mars can prosper on its own?” Everyone pictures the landing. The boots on red soil. The flag. Musk isn’t thinking about the landing. He’s thinking about what happens when the ships stop coming. Musk: “The key test being: can Mars survive if the resupply ships stop coming?” That’s not a milestone. That’s a survival audit. If Mars needs Earth to exist, Mars isn’t a civilization. It’s a campsite. The distance between a base and a civilization is the distance between receiving supplies and making them. Musk: “It’s not just that you’d need to build, for example, a chip fab on Mars, but you need the ability to build fabs.” Not the factory. The ability to build the factory. Not the chip. The capacity to create the machine that creates the chip. Mars doesn’t need the outputs of civilization. It needs the ability to regenerate civilization from scratch. Musk: “What really matters is that Mars is self-sustaining. That we are truly a multi-planet species, such that we’ve achieved planetary redundancy.” Planetary redundancy. A cold engineering term for the most existential project ever attempted. Two independent copies of everything it took 10,000 years to build. Running simultaneously. So one can fail without taking everything with it. Every civilization in history was one catastrophe from permanent erasure. We accepted that as a condition of existence. Musk accepted it as an engineering problem. Musk: “There’s always some risk of an annihilation event on Earth.” One event on one planet. And the universe goes back to unfolding in front of nothing. Musk: “The probable lifespan of consciousness increases dramatically as soon as we are a multi-planet species.” The lifespan of consciousness. Not of humans. Not of the species. Consciousness. He’s not preserving people. He’s preserving the phenomenon. The thing the universe spent 13.8 billion years producing. The only thing in existence that knows it exists. We are not backing up a population. We are backing up the universe’s awareness of itself. If Earth goes dark and Mars holds, consciousness doesn’t just survive. It proves it was never dependent on one rock. It proves awareness can outlive the place that first produced it. Earth was never the home of consciousness. It was the womb. And the purpose of a womb is to produce something that outgrows it. We spent 300,000 years building everything we know on a single planet and praying nothing went wrong. Musk is building the first civilization ever designed to survive its own origin.
