IS LIVING ON MARS A BILLIONAIRE'S FANTASY?
A base on the Red Planet might be filled with some annoying housemates, but that doesn't mean we can't aspire to setting up a permanent settlement there
On 18 November 2023, SpaceX launched one of the largest rockets ever constructed. Starship marks a step change for humanity's relationship with space - a reusable rocket so powerful that it could carry the mass of today's painstakingly built International Space Station in just two to three launches, and likely quite a bit cheaper. Dreams from the days of the Apollo programme, long squashed by the high cost of space access, are returning and with them, arguments about the value of space to our species.
As with many experimental rockets, Starship failed to achieve all of its goals. Its first rocket stage exploded, and the second needed to self-destruct. Reactions are illustrative of the divide between space analysts and much of the media (and the public). To many, it was proof of failure. Those in the space-geek community generally viewed it as a success. Starship, a rocket the size of a skyscraper, soared 150km (over 90 miles) at high speed, gathering a trove of valuable data before malfunctioning. Not failure progress with a bang.
THEATRE OF HOPE
Space settlement researchers occasionally find themselves arguing about the value of space. For the most gung-ho space advocates, it's a theatre of all hope. It's a way to get rich from asteroid resources, to save the environment by offloading people and industry from an overburdened Earth, and a chance to create a second home for humanity that could survive the death of our planet. Others question why we spend so much on space when we have so many problems on Earth. Some wonder darkly if space billionaires are cultivating a Martian redoubt as a kind of off-world bunker, in case our planet is ruined by climate change or war.

COULD MARINE CLOUD BRIGHTENING HELP US FIGHT CLIMATE CHANGE?
The theory behind marine cloud brightening is that brighter or whiter clouds reflect more sunlight back into space.
IS IT SAFE TO RUN EVERY DAY, OR SHOULD I DITCH MY RUN STREAK TO SAVE MY KNEES?
A running streak, where you run every day without taking rest days, can be highly motivating and beneficial for overall fitness. Running is great cardiovascular exercise and isn't to be discouraged (and finding a routine with some consistency is great). Getting a bit of exercise as often as possible is also hugely beneficial for your mental health.
WHAT MAKES THE MEDITERRANEAN DIET SO GOOD FOR US?
The Mediterranean diet may help you live longer, especially if you also adopt the lifestyle of people living near the Med during the 1950s.
WHAT IS MEXICO'S BLUE HOLE?
The world's deepest blue hole (marine sinkhole) lies off the coast of Mexico's Yucatán Peninsula. It's at least 420m (1,378ft) deep, but explorers still haven't found its bottom.
HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?
Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys. It plays a critical role in various bodily functions, including regulating metabolism, reducing inflammation and helping the body respond to stress. While essential for our health, chronic elevation of cortisol levels can lead to several issues.
THE LUNGFISH
In 1836, European scientists discovered a peculiar animal from the River Amazon that they struggled to identify. Its eel-like body was a few feet long and its air-filled lungs persuaded anatomists it must be a reptile.
ARE WE THE ONLY SPECIES TO HAVE BEEN THROUGH A STONE AGE?
The Stone Age might conjure up images of early humans, sitting around a campfire or hunting prehistoric beasts, but evidence shows that we're not the only species that has learned how to work with stone tools. Wild chimpanzees (Pan troglodytes) use stone tools to crack open nuts.
Should we scrap daylight saving time?
Most of us look forward to the extra hour we get in bed every October, but researchers argue that changing the clocks twice a year harms our health
THE INTERNET OF ANIMALS
SCIENTISTS ARE USING ELECTRONIC TAGS AND SATELLITES TO TRACK WILD ANIMALS AND CREATE A DATA NETWORK THAT COULD HELP US ADDRESS THE BIODIVERSITY CRISIS
MUSIC FOR A DISTRACTED GENERATION
The number of things competing for our attention is often overwhelming. Can dreamy soundscapes created with neuroscience help our bewildered brains to concentrate?
