The sky is being privatised and divided - before anyone got a vote. Deeply reported films on who is quietly claiming low orbit, the radio spectrum, and the Moon, and what that land-grab costs the rest of us on the ground.

Mind & Meaning
The Greenland shark lives roughly 400 years — longer than any other vertebrate on Earth — and when scientists sequenced its genome in September 2024, they found the species' extraordinary lifespan appears to rely on enormous quantities of duplicated DNA-repair genes, in a biological strategy still keeping individual sharks alive that were born during Shakespeare's lifetime.
Somewhere in the cold dark water below the Arctic ice, several individual Greenland sharks alive today were almost certainly already…

A massive star appears to have exploded twice — first as a supernova, and then again days later when the two neutron stars its first explosion had created violently crashed into each other — in what astronomers announced in December 2025 may be the first event of its kind ever observed, so unprecedented that physicists have invented a new word for it: "superkilonova"
The unusual sequence began with a signal from a routine source. On 18 August 2025, the LIGO gravitational wave detectors in the United…

Mind & Meaning
The psychology of ambition, isolation, and meaning under extremes — and what frontier life teaches us about being human.
The ocean produces roughly half of Earth’s oxygen — not the rainforest, which uses up most of what it makes — through photosynthesis by phytoplankton, microscopic marine organisms so abundant that a single teaspoon of seawater can contain as many as a million of them.
The smell of the ocean — that sharp, clean scent people travel thousands of kilometres to breathe — is not salt, which has no real smell, but partly dimethyl sulphide: a sulfur gas released when compounds made by microscopic marine algae are broken down by bacteria, death, and grazing in the sea.
A space telescope that has spent 22 years detecting the most powerful explosions in the universe is now falling toward Earth, and a startup in Arizona built its rescue craft in seven months flat — a schedule Science described as almost unheard of for a NASA mission
In 1971, Apollo 14 astronaut Stuart Roosa carried hundreds of tree seeds around the Moon in a metal canister inside his personal kit. When the seeds returned to Earth, many were germinated by the U.S. Forest Service and planted as “Moon Trees” — ordinary-looking trees that, decades later, showed no discernible difference from trees whose seeds had never left Earth.

A giant barrel sponge growing on a Caribbean reef off the island of Curaçao was estimated to be roughly 2,300 years old when it was photographed by researchers — meaning it began growing at the bottom of the ocean during the lifetime of Hannibal and survived as a single continuous living organism, filtering seawater on that exact spot, from before the founding of the Roman Empire until it died of disease in 2012

A blind cave salamander called the olm is projected to live past a hundred years, and biologists still cannot explain how it ages so slowly
About Space Daily
Space, science, and the human side of the frontier. Since 1995.
Space Daily is an independent publication covering three connected beats: the space industry, the science behind it, and the psychology of ambition, isolation, and meaning under extremes. Founded in Tokyo in 1995, we’ve built a thirty-year archive of rigorous reporting on the people, missions, and ideas pushing humanity outward — and on the human dynamics shaped by frontier life. The same ambitions, pressures, and patterns of mind that drive humanity to the stars also shape how we live on Earth. We employ modern AI technologies to support our editorial workflows; every published piece is editorially directed and reviewed.
