6-min readJeff Bezos and Elon Musk both want to colonise space. Nasa is also trying to put people on to the dusty surface of Mars.Plenty of experiments have been conducted to see whether plants can flourish in space.It was a small pilot step for trialling a potential nutrient source, one possibly big leap - at least the experimenters hope - for the future of space travel.
Cells from a cow are fed the things they need to grow, like amino acids and carbohydrates. The cells multiply until muscle tissue forms, and eventually becomes meat that you can eat. This process is called "cultivation" or "proliferation". Larry Connor, Eytan Stibbe, and Mark Pathy launched from Kennedy Space Center in Florida, accompanied by former astronaut Michael Lopez-Alegria. They were due to return to space on Sunday 24 April, after which the cells will be closely analysed.Even if the experiment is a success and it is proven that meat can be grown in space, it doesn't necessarily mean it's a good idea.
Aleph Farms says it believes the sterility problem can be handled, particularly in space where relatively small quantities of meat would need to be produced. But contamination would be disastrous for a community on Mars - the space equivalent of a crop failure. But there are other considerations when planning long space missions - like the mental health of astronauts.
