A free app for Android, by NASA.

In the last 60 years, NASA has sent hundreds of astronauts into space. In addition to exploring the universe, they have studied the effects of microgravity on the growth of plants, and found ways to use this knowledge for benefit on Earth. 

This is an app that helps you understand the effects of microgravity on plants, and how NASA is using this knowledge to help people on Earth.

The first thing you will need to do is explore the station. There are many things to see and do on the station. Explore the different areas of the station, and try to understand what is happening in each one.

After you have explored the station, it is time to start the experiment. In this experiment, you will be cutting plants, and the more you cut, the more you will grow. It is your job to make sure that the plants are growing properly, and that they are healthy.
