Spacecraft

Although the main spacecraft was built by Lockheed Martin, its instruments and components come from all over the world. Juno is shipped in pieces to the Kennedy Space Center in Florida, where it’s assembled and put on top of an atlas rocket that will blast it off into space.

While building the spacecraft, engineers take extreme care to keep it clean. They work in a clean room and wear special suits that prevent dirt, dust, and hair from contaminating the craft.

Engineers have to test every part of the spacecraft to ensure that it will survive the harsh environment of outer space. They simulate the conditions that Juno may encounter in test chambers. For example, they see how well components can withstand heat and vibration – a test often called shake ‘n’ bake.
