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.

Within hours of reaching microgravity, astronauts’ body fluids shift toward the head, dulling smell and taste — one reason NASA monitors daily nutrition so closely as crews fight the muscle loss space exercise alone cannot fully prevent
The first thing that happens to a body in orbit is that it starts to rearrange itself.

A University of Tokyo study found that students who wrote schedules on paper recalled them better than those who used a tablet or phone — suggesting old-fashioned lists may give the brain stronger memory cues
Give a person a diary, a tablet and a phone, ask them to write down the same set of appointments, then quiz them an hour later, and the one who used paper tends to recall the simpler details more reliably.

The psychology of ambition, isolation, and meaning under extremes — and what frontier life teaches us about being human.
Voyager 1 crossed into interstellar space in August 2012, yet it remains inside the gravitational reach of our Sun — true departure from the solar system, via the Oort Cloud, won't happen for 30,000 years
Proxima Centauri b is our closest known habitable-zone exoplanet, just over four light-years away, and it may be warm enough for liquid water if it has kept an atmosphere. But that “if” is enormous: its red-dwarf star blasts it with extreme radiation strong enough, in some models, to strip an Earth-like atmosphere away.
In a 3.5-billion-year-old clay-rich rock from Gale Crater, NASA’s Curiosity rover identified 21 carbon-based molecules — including a nitrogen-bearing ring structure linked to the chemistry that can precede RNA and DNA — showing that ancient Martian sediments can preserve surprisingly complex organic chemistry for billions of years.
For billions of years, Earth’s magnetic field may have been doing something unexpected: helping guide particles stripped from our upper atmosphere across the 385,000 kilometres to the Moon, where they became trapped in lunar soil — a 2025 finding that adds a surprising new argument for studying the regolith beneath a future Moon base.

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.
