Will there be gardens in space?
Astronauts on board the International Space Station(ISS) recently made history by taking bites of some red romaine lettuce(生菜). They became the first humans to eat food that was grown completely in space.
The lettuce was planted on the ISS in a small greenhouse called “Veggie”, which uses LED lights to help plants grow in space.
First, the astronauts cleaned the lettuce with special sanitizing wipes(消毒纸巾) and then ate it with some salad dressing(色拉酱).
“It was one small bite for man, one giant leap(飞跃) for...our journey to Mars,” one astronaut Scott Kelly later posted on social media.
Space vegetables are a part of the NASA experiment called “Veg-01”, a study on how plants grow away from the effects of Earth’s gravity(引力). It will allow astronauts to grow and eat their own food during long space explorations(探索).
“If we are ever going to Mars someday, we’re going to need a spacecraft that is much more self-sustainable(自给自足) in its food supply,” said Kelly.
Growing fresh plants on a spacecraft may also provide oxygen and help keep astronauts alive, NASA said.
“Veg-01” started in May 2014. The first batch(批) of vegetables took 33 days to grow in space before they were taken back to Earth for a safety check.
After making sure it was safe to eat, astronauts planted a second batch on July 8. They let the plant grow for another 33 days and were then able to eat it.
Astronauts usually only get some fruit and vegetables when a supply ship comes to the ISS. Now with the vegetables grown in space, they can eat whenever they want.
