Editorial Team

The Space Daily Editorial Team produces content across our two editorial pillars: space industry news and Mind & Meaning. We cover launches, missions, satellites, defense, and the technology of getting humans to space, alongside the psychology of ambition, isolation, and meaning under extremes. Articles reflect our team's collective editorial process, source verification, drafting, technical review, and editing, rather than a single writer's work. Space Daily takes editorial responsibility for content under this byline. For more on how we work, see our editorial policy.

Constellations

The Hubble Space Telescope’s main mirror was ground to the wrong shape by 2.2 micrometers, about one-fiftieth the width of a human hair, and the error was only caught after launch because the device used to verify the mirror on the ground had itself been built wrong

Hubble's primary mirror was polished to perfection, just to the wrong shape, because the device built to measure it had a chipped flake of paint that threw its internal geometry off by 1.3 millimeters. The mirror was checked against a ruler that was itself broken.

The Pioneer 10 and 11 spacecraft were found to be decelerating slightly more than gravity could explain, and for thirty years physicists wondered if Newton was wrong before realizing in 2012 that the answer was the probes’ own waste heat gently pushing them backward at a billionth of Earth’s gravity.

For three decades, two NASA probes drifting toward interstellar space appeared to be decelerating by an amount that gravity alone could not explain. The resolution turned out to be the spacecraft warming themselves.

Science

When the first draft of the Neanderthal genome was published in 2010, researchers found that most people with recent ancestry outside Africa carry between 1 and 4 percent Neanderthal DNA — meaning a human group whose physical traces vanished around 40,000 years ago still survives, in fragments, inside the cells of billions of people alive today

When the first draft of the Neanderthal genome was published in 2010, researchers found that most people with recent ancestry outside Africa carry roughly 1 to 4 percent Neanderthal DNA.

Human Behaviour

Every year, 27.7 million tons of Saharan dust crosses the Atlantic Ocean and settles on the Amazon rainforest, delivering roughly the exact amount of phosphorus the rainforest loses to runoff, which means the world’s most productive forest is fertilised, year after year, by the slow erosion of the planet’s largest desert thousands of miles away.

The connection is one of those facts about the planet that nobody designed and almost no one outside the relevant atmospheric science literature knows about.

Science

The deepest part of the human gut contains a peripheral nervous system of about 500 million neurons — more than the spinal cord — operating with enough independence that researchers sometimes call it the “second brain,” and the body’s emotional responses are frequently well underway in the gut before the conscious mind has been informed about whatever it is responding to

The standard cultural framing of where one's nervous system is located tends to assume that the nervous system is, in any meaningful sense, all in the head.

Deep Space

The Earth’s magnetic field has reversed itself completely roughly 183 times in the last 83 million years — the last reversal happened about 780,000 years ago — and during the transition the field’s strength drops to a small fraction of normal, leaves the planet briefly more exposed to solar radiation, and creates auroras at latitudes where they otherwise never appear.

The Earth's magnetic field is, by every available measurement, the structural feature that protects the surface of the planet from most of the solar radiation that would otherwise sterilize it.

Science

The most accurate atomic clocks in operation now lose less than one second every 30 billion years — and the reason this matters isn’t precision for its own sake, it’s that gravity itself slows time slightly, and these clocks are now sensitive enough to measure the difference between sitting on the floor and standing upright in the same room.

There is a particular fact about the most precise atomic clocks currently in operation that the wider cultural register has, on the available evidence, not yet adequately absorbed.
