A new U.S. law describes what NASA (the National Aeronautics and Space Administration) will do in the future. President Obama signed it on Monday.
The law says NASA will:
- Keep the International Space Station open until at least 2020
- Help companies use space travel for business
- Find new ways to get astronauts out of Earth's orbit
- Develop a new vehicle for taking people into space
- Spend money on "green" aviation -- the kind that's less harmful to the environment.
