For the first time, plants from the earth are growing on the moon. The China National Space Administration(中国国家航天局) showed photos of cotton seeds sprouting into life. It said they were among several plants that were "growing well". The plants are part of a Chinese project to the far side of the moon. Project leader Liu Hanlong said the cotton was the first to sprout. He said he chose the plants because they were small, strong and could grow in the difficult conditions on the moon's surface.

Professor Liu Hanlong said the project's aim was to understand how plants grow outside of the earth and the longterm aim is to develop plants that can grow on the moon or on planets like Mars. The professor said the team was looking at the future survival (生存) in space. Learning about these plants growing could allow us to lay the foundation for (为……打下基础) starting a space base.
