  • Flowers in Space

    Astronauts on the space station grew flowers called zinnias! Testing how plants grow in space is important. On long missions, astronauts will need to grow their own food.

  • Prandtl-D Aircraft

    This aircraft is shaped like a boomerang. The shape helps the plane use less fuel. To help them design this airplane, people studied how birds fly.

  • Desert Crater

    This crater is almost perfectly round. It is 1.9 kilometers wide. It is in the western part of the Sahara desert in Africa. A meteorite made the crater more than 10,000 years ago!

  • Shock and Awesome

    NASA used a special tool to take this picture. It shows the shock waves made by a plane (in middle) as it pushes through air. The plane is flying faster than the speed of sound!
