Today is World Nutella Day, which seems like an excellent opportunity to explore the time that a spoonful of chocolate hazelnut spread nearly caused an interplanetary incident.
It’s 2013, and six people are living on Mars – or at least as close as you get at the moment. They’re isolated in the HI-SEAS analog habitat in Hawaii, cut off from life on Earth for four months. Their NASA-funded mission is to explore the ‘Risks associated with an inadequate food system.’ The problem is that, during long-duration space missions (such as a mission to Mars), astronauts will inevitably get tired of eating rehydrated meals. So then they will eat less, lose weight, miss out on essential nutrients and potentially compromise the mission.
One possible solution is to allow astronauts to cook using shelf-stable (long-life) ingredients. But that means the crew needs extra cooking equipment and spends time preparing meals and cleaning up. So does the psychological benefit of better feed outweigh the resource costs?
That was what the crew of the first HI-SEAS mission were researching, comparing pre-packaged instant meals with ones they cooked themselves. The study tracked the crew’s satisfaction with their meals, alongside their use of power, water, food and other supplies.
For principal investigator Dr Kim Binsted, the project’s goal was to work out the most efficient grocery list for Mars in terms of cost, mass, taste and nutrition. By the end of four months, the researchers would have a good grasp of which food items were essential and which ones should stay on Earth.
The Mission 1 Crew was Simon Engler, Dr Sian Proctor, Kate Greene, Dr Oleg Abramov, Dr Yajaira Sierra-Sastre, Angelo Vermeulen (mission commander).

Traditionally, greenhouses can be quite energy and water intensive, running on fossil fuels which are detrimental to the environment. This is why more and more UK homeowners and gardening enthusiasts are designing their greenhouses with sustainability in mind. In this article, we’ll talk you through the different areas where you can consider improving the sustainability of your greenhouse and how these could benefit you – so that you can garden with a green conscience as well as a green thumb.
Using wallpaper to update your space brings in patterns and textures that plain old paint just can’t match. Especially with numerous peel-and-stick wallpaper options, you have various designs you can choose from without having to fully commit for years.
When it comes to interior design, it can be tricky to know what decor trends to buy into and what to skip. While 2023 trends included leaning into bold color, maximalist style, dark countertops, and a nod to Art Deco, some others like all-white interiors, sparse spaces, and wiggly furnishings weren't as popular. They may not be entirely trends to skip, but at least ones to put on the back burner if you are currently designing or updating your space. Looking for some advice? We sat down with interior designers to get their take on design trends they wish they'd skipped.
It’s at this time of year, I think, that a polytunnel or greenhouse really comes in handy in the garden. Over the summer it may just be a tangle of tomato vines – productive, but a space that you really only go in to keep up with the watering chore, or to harvest ripe tomatoes. You know you’re going to come out with green stains on your clothes and hands that smell funny – tomatoes are like that. Those tomatoes will hang on longer into the autumn than you thought they would, and by the time you’ve cleared out the polytunnel the season will be so far advanced that it will be cold and dark and your crop of overwintering salads will barely be growing – just marking time until the days are long enough for them to actually grow.
The ice cream experiments continue, with a spate of frozen yoghurt trials. I have never been a big fan of chocolate ice cream, but something I read online (and a half-empty jar of Nutella) prompted me to give Nutella frozen yoghurt a go!
Just over a year ago, when we were celebrating the 50th anniversary of the first Moon landing, I talked about the lack of diversity in space and mentioned Mary Jackson. In 2016, the movie Hidden Figures shared the stories of Mary Jackson and two other Black female mathematicians – Katherine Johnson and, Dorothy Vaughan. They worked at NASA when a ‘computer’ still meant a person carrying out mathematical calculations. The film is based on a book by Margot Lee Shetterly, which I am reading at the moment. The book offers a more detailed and accurate account of the prejudice these women (and others) had to overcome.
Can we grow food on the Moon or Mars? That was the question that started Dr Wieger Wamelink, ecologist and exobiologist at the University of Wageningen in the Netherlands, on a research quest in 2013.
Getting a plant payload into space is rarely straightforward. In this episode, Emma the Space Gardener chats with Dr Carl Carruthers, who started out sending his own research projects into space and then became Chief Scientist at Nanoracks. There he worked on projects to send palm tree seeds to the International Space Station for the UAE and to design a kit to turn school kids into space farmers.
