Fifty years after humans first set foot on the moon, Earth’s only permanent natural satellite is back in the news with China’s successful landing on the moon’s as-yet-unexplored far side. This month, Horizon looks at how Europe is contributing to moon research. We hear from the European Space Agency’s director of human and robotic exploration about their plans to send a robot and then humans to the lunar surface in the 2020s, and speak to the scientists trying to fill the holes in our understanding of how the moon was formed. We also hear how we could solve the puzzle of where water on Earth originated by analysing volatile substances from the moon, and take a look at the methods and facilities being developed to protect precious extra-terrestrial samples from human contamination.

How scientists are piecing together the history of the moon

In the solar system’s early days, a first Earth is thought to have been pulverised by a planet that scientists call Theia. We don’t know what it was made of or where it came from, only that it may have been the size of Mars. The powerful collision destroyed both planets so completely that scientists can only guess what they were like.

New findings suggest that if the moon formed after a giant impact after water had had been received, it should have gotten a share of that water. The question is - where did it go? Image Credit - ANDY SMITH ASTRONOMY

The moon’s water: where did it come from – and where did it all go?

Fragments of moon rock brought back from the lunar surface by astronauts on the Apollo space missions are providing new insights about where our planet’s life-giving water came from.

How to keep lunar samples safe

A lunar rover that can analyse samples in situ and a Europe-wide facility to store extraterrestrial samples will help to protect moon samples from contamination and increase their usability in scientific experiments.

‘The moon is a history museum and we’ve only visited the gift shop’

Humans have not set foot on the moon since 1972, when the last Apollo mission came back to Earth. That could all change in the coming years, however, as entities like the European Space Agency (ESA) are preparing not just to return, but to build a permanent base on the surface.

Quantum technologies

The so-called second quantum revolution is in full swing, with scientists not only able to understand what happens at a sub-atomic level but also control this quantum behaviour enough to develop new technologies. Six months after the launch of the EU’s €1 billion quantum flagship initiative to kickstart a European quantum technologies industry, we take a look at the potential of quantum to revolutionise our future. We speak to one researcher who is helping to build a quantum computer about the global race to do this and how Europe is faring. We take a look at the threat and promise of quantum technologies in the field of cryptography and find out how quantum simulators can be used to solve non-quantum problems. And finally, we speak to the scientists who are using quantum mechanics to improve the performance of brain scanners and better diagnose medical conditions.

Modern-day malnutrition

How did European eating habits go so wrong? We have a plentiful supply of fresh food yet, according to Eurostat, one in every two people in Europe is either overweight or obese, leading to problems such as cardiovascular disease, high blood pressure and lifestyle-related diabetes. In May, we delve into the complex science of healthy eating to understand how to tackle modern-day malnutrition. We speak to public health expert Knut-Inge Klepp about the complex factors determining food choice and how to improve the diet of teenagers. We find out how scientists are working to improve the zinc content of crops to prevent the ‘hidden hunger’ of micronutrient deficiency and look at the importance of widening the diversity of grains that we eat – both for our health and for the environment. We also explore what’s behind the nutritional self-sabotage of eating disorders.

Why meerkats and mongooses have a cooperative approach to raising their pups

Raising children can be a tough job, especially when doing it alone, but some animals like meerkats and mongooses work together to raise their young. Studies of these cooperative creatures are revealing how this highly social behaviour evolved and is shedding light on the roots of our own species’ collaborative abilities.

Which climate innovations will really limit global warming?

From a chemical-free spray that turns sand into lush green land, to a caterer who serves planet-friendly dishes, and from technology that makes stronger concrete with less cement, to insect farms that produce fish food and fertilisers, there is no shortage of ideas to reduce emissions. But which ones work best?
