Genetically modified salad could be crucial to keeping the bones of humans on Mars healthy.
This is according to researchers from the University of California who have added a human gene to regular lettuce.
Weak bones are a problem humans will face in space because living in microgravity environments leads to a loss of bone mass. Somen Nandi, of the University of California at Davis, said: “Astronauts can carry transgenic seeds, which are very tiny — you can have a few thousand seeds in a vial about the size of your thumb — and grow them just like regular lettuce.
NASA plans to grow food on future spacecraft and on other planets as a food supplement for astronauts.Astronauts have proven that they can grow lettuce on the International Space Station so growing lettuce on Mars could be possible.that time in space can weaken human bones and there’s concern this could prevent long distance space travel.: “Nasa has learned that without Earth’s gravity affecting the human body, weight-bearing bones lose on average 1% to 1.
