世界首款“火星番茄醬”

胡金瑩

最近，美國亨氏公司發(fā)布了全球首款“火星番茄醬”。制作這款番茄醬的番茄是研究人員耗時九個月，在與火星相似的土壤、溫度和水環(huán)境中培育的火星版番茄。然而，亨氏的“火星番茄醬”目前并不對外銷售。

1Recently， Heinz has just released a special “Marz Edition” ketchup， a kind of ketchup made from tomatoes that were grown in agricultural conditions which imitated those on Mars. The site for this feat was the “Red House”， a greenhouse at the Florida Institute of Technology's Center for Advanced Manufacturing and Innovative Design. There， a team of researchers led by Andrew Palmer， an associate professor of biological science at the school's Aldrin Space Institute， spent thousands of hours fostering tomatoes with resources similar to what future Mars farmers would have.

2Instead of sunlight， for example， the tomatoes were exposed to LED lights. Researchers also brought in roughly 7，800 pounds of Mojave Desert soil， a relatively close approximation of the red planet's rocky regolith （風化層）. In order to maximize the project's chances of success， Heinz's agriculture experts chose four tomato varieties from the brand's seed catalog that they thought would be most resilient （有適應力的） in the Mars?like environment. Two succeed; two didn't.

3Though the process may seem as straightforward and fruitful as what Matt Damon's Mars?stranded characters undertook in 2015's The Martian， there's a lot of careful work that goes into it， from achieving the perfect balance of nutrients in the soil to determining how the plants should be organized. In this case， the researchers found that placing various kinds of plants together in a container rather than giving each its own container could help to increase microbe diversity and decrease the spread of disease. Actually， this is not the first time that scientists have tried to grow plants under Martian conditions， but those studies have mainly concerned “short?term plant growth”.

4“What this project has done is look at long?term food harvesting. Achieving a crop that is of a quality to become Heinz ketchup was the dream result and we achieved it，” said one of the researchers.

5Unfortunately， for ketchup lovers and space enthusiasts， Heinz's “Marz Edition” ketchup isn't for sale. But you should be assured （放心） that if you end up living on Mars， there's a good chance that you'll have ketchup to put on your Martian fries.
