最近，美国亨氏公司发布了全球首款“火星番茄酱”。制作这款番茄酱的番茄是研究人员耗时九个月，在与火星相似的土壤、温度和水环境中培育的火星版番茄。然而，亨氏的“火星番茄酱”目前并不对外销售。

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 Insti⁃tute 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 re⁃sources similar to what future Mars farmers would have.

2Instead of sunlight, for example, the tomatoes were exposed to LED lights. Research⁃ers also brought in roughly 7,800 pounds of Mojave Desert soil, a relatively close approxi⁃mation of the red planet's rocky regolith (风化层). 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 (有适应力的)in the Mars⁃like envi⁃ronment.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'sThe 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.
