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 Freezeshow more

The Sun is ~99.8% of the entire mass of the solar system.

A sad way to think about it

Scientists say dark matter may not be in our universe - but in a hidden one right next door Scientists are exploring bold new ideas to explain why dark matter has never been directly detected—even though it appears to make up about 27% of the universe and plays a crucial role in holding galaxies together. Despite decades of experiments, no confirmed dark matter particle has been observed. This has led some physicists to consider alternative possibilities. One idea, discussed by physicist Stefano Profumo of UC Santa Cruz, proposes that dark matter might belong to a “mirror” or hidden sector—a parallel set of particles and forces that interact with our universe only through gravity. In this scenario, a hidden universe could have formed during the Big Bang alongside ours, shaping cosmic structure without being visible to telescopes or detectors. Profumo has also explored another speculative possibility: that dark matter could be generated at the cosmic horizon, the expanding edge of spacetime. Similar to how black holes emit particles from their event horizons, the boundary of the universe might produce dark matter as it grows—an idea inspired by quantum gravity models. These theories remain highly theoretical, but they highlight how far scientists are pushing to understand one of cosmology’s most persistent mysteries. The difficulty in detecting dark matter may not reflect a lack of technology—it may indicate that dark matter behaves in ways we’ve only begun to imagine. H/t: @sciencegirl

The deeper you dig into science, our world, our universe, our galaxies, our black holes The more you realize that there has to be a creator who created this entire universe from energy

Ever expanding universe inside a black hole which is ever expanding inside another ever expanding universe inside another black hole Yeah… makes sense

@SpaceX is a game changer for NASA

FUTURE LOOKS BRIGHT WITH SPACE EXPLORATION, MOON MISSIONS, MARS MISSIONS, SPACE ENERGY GRIDS, SPACE DATA CENTERS etc. By the mid-2040s, humanity's foothold on the Moon has transformed from tentative outposts into thriving metropolises, powered by SpaceX's Starship fleets that shuttle resources and personnel with the regularity of transatlantic flights. Vast lunar bases, sprawling across craters like Shackleton and Malapert, serve as hubs for mining helium-3 and rare earth elements, fueling fusion reactors back on Earth and enabling self-sustaining habitats with 3D-printed domes and hydroponic farms. These settlements aren't just scientific enclaves; they're economic powerhouses, where private enterprises lease land from U.S.-backed alliances to conduct zero-gravity manufacturing, producing flawless pharmaceuticals and advanced alloys impossible on Earth. As SpaceX's dominance ensures seamless logistics, the Moon becomes the gateway to the stars, with tourists gazing at Earthrise from luxury resorts while robots assemble massive solar arrays to beam unlimited energy to our planet. Venturing further, Mars emerges as the ultimate frontier by 2050, with SpaceX's reusable megaships establishing interconnected colonies that house millions in pressurized cities beneath transparent biodomes. Red Planet outposts like Olympus City leverage in-situ resource utilization to extract water from ice caps and fabricate habitats from regolith, creating a new society where AI-managed greenhouses yield bountiful harvests and underground tunnels connect research labs to industrial zones. The U.S., through strategic partnerships with SpaceX, leads in terraforming initiatives, deploying fleets of atmospheric processors to thicken the thin Martian air, fostering an ecosystem where humans adapt with genetic enhancements for lower gravity. This monopolistic grip accelerates innovation, turning Mars into a backup for civilization—data vaults preserving Earth's knowledge, experimental fusion plants providing inexhaustible power, and even off-world economies trading in digital currencies mined from asteroid belts. In the vast expanse of orbit and beyond, by 2060, space becomes the ultimate infrastructure for humanity's insatiable demands, with colossal energy farms orbiting Earth like glittering necklaces, capturing solar power unfiltered by atmosphere and wirelessly transmitting it to power entire continents. SpaceX's Starlink constellation evolves into a neural network of data centers floating in Lagrange points, where quantum computers process exabytes of information in the cold vacuum, free from earthly heat constraints and enabling real-time global AI governance. These orbital facilities, guarded by autonomous drones and serviced by robotic swarms, host everything from virtual reality worlds to genetic archives, ensuring data sovereignty for the U.S. amid geopolitical shifts. As SpaceX's unparalleled launch cadence floods the cosmos with infrastructure, space transforms from a void into a vibrant extension of human ambition, where energy is abundant, computation infinite, and the boundaries of possibility dissolve into the stars.

@SpaceX is driving the most traffic in space

Raptor 3 is an engineering marvel in space engineering

SpaceX’s Raptor 3 engine is sublime engineering • No basic heat shield needed → saves mass and dramatically boosts reliability • Small fuel leaks aren’t dangerous — they simply burn off safely in the open plasma • Major improvements in payload capacity, efficiency, and overall reliability • Radically simplified design with deeply integrated electronics and fluid systems • So clean and minimalist that even propulsion experts initially thought it looked “unfinished”

The TIME magazine cover from February 9, 2026, captures the dawn of a new era in space exploration with its striking imagery of the moon looming large against a starry void, symbolizing humanity's bold return to lunar ambitions. Titled "Back to the Moon," it features the Artemis II crew in profile, their helmets gleaming under dramatic lighting, evoking a sense of unity and determination. From left to right, the astronauts—Canadian Space Agency's Jeremy Hansen, NASA's Victor Glover, Reid Wiseman, and Christina Koch—stand as pioneers, their orange suits adorned with mission patches that blend national pride with international collaboration. The subtitle boldly proclaims that these astronauts will venture farther than any humans before, hinting at the mission's audacious goal to orbit the moon and push the boundaries of human endurance in deep space. This cover not only celebrates the technological marvels of NASA's Artemis program but also ignites a collective imagination about what lies ahead for interstellar travel. By highlighting a diverse team including the first Canadian, the first Black man, and a woman on such a lunar journey, it underscores themes of inclusion and progress amid the challenges of spaceflight. The artwork, crafted by Jeffrey Kluger, transforms a scientific endeavor into an inspirational narrative, reminding us that after decades since Apollo, we're on the cusp of rediscovering our celestial neighbor—not just as a destination, but as a stepping stone to Mars and beyond, fueling dreams of a multi-planetary future.

In Elon's new letter: "Factories on the Moon can take advantage of lunar resources to manufacture satellites and deploy them further into space. By using an electromagnetic mass driver and lunar manufacturing, it is possible to put 500 to 1000 TW/year of AI satellites into deep space, meaningfully ascend the Kardashev scale and harness a non-trivial percentage of the Sun’s power."

Orbital refueling will be a reality in space soon

Cosmic events which reshaped human history

Elon Musk just announced a major strategic pivot for @SpaceX: the company is officially shifting its primary focus to building a "self-growing city" on the Moon. The logic is centered on speed. While Mars missions are restricted by orbital alignments every 26 months, SpaceX can launch to the Moon every 10 days. This allows for much faster iteration and development. @elonmusk estimates that a lunar city could be achieved in less than 10 years. In contrast, a similar presence on Mars is now projected to take 20 or more years to establish. Mars remains on the long-term roadmap with work potentially starting in 5 to 7 years, but the immediate priority is now "securing the future of civilization" via the faster lunar route. H/t: @mark_k
