舌尖上的太空

上图为NASA拍摄的国际空间站内种植的太空生菜。2015年8月10日，生活在国际空间站内的宇航员们已经准备好品尝他们从蔬菜种植系统中收获的红生菜的样本。这种蔬菜种植系统平时用来试验宇航员们在太空中种植的蔬菜。

Astronauts on the International Space Station are ready to eat on 10 August 2015 a sample from their harvest of a crop of 'Outredgeous' red romaine lettuce from the Veggie plant growth system that tests hardware for growing vegetables and other plants in space.

太空蔬菜采用的是营养液无土栽培的方法

建立一个电脑化的蔬菜种植系统是载人飞船前往火星这一项目当中重要的一步。此项目的目标是评估该种植系统对于NASA火星计划的可持续性。

The goal of the project is to evaluate its sustainability in NASA?s ongoing Journey to Mars program.

提到太空生菜的味道，宇航员们纷纷表示“味道好极了，并且饶有兴趣地将醋和橄榄油倒在生菜上调味品尝。[Photo：Sina]

Most astranauts praised the taste of the lettuce. They also pour vinegar and olive oil on the lettuce to improve its taste.

种植成功并且能够品尝到太空蔬菜对于太空研究意义非凡，这意味着宇航员能更好地应对严酷的太空环境，保证基本的生活需求，并且能够延长太空探险任务的期限。
