NASA Discovery: 7 Earth-Sized Planets

Scientists from NASA announced on February 22 that they have discovered seven planets orbiting a nearby star. The planets are all about the same size as Earth, and three of them are in what scientists call the “habitable zone.”

(The habitable zone is the area of space around a star where a planet is most likely to have liquid water on its surface. Scientists believe water is necessary for anything to live on a planet.)

Astronauts Will Turn Trash Into Tools

Astronauts on the International Space Station (ISS) may soon be able to turn their used forks and knives into tools and satellite parts.
Tethers Unlimited Inc., an aerospace technology company, has developed a system that combines a waste recycling machine with a 3D printer.
Astronauts will put waste items made of plastic into the recycling machine, called the Positrusion Recycler. When they press a button, the Recycler will sterilize and melt down the plastic and turn it into 3D filament.
