Spacecraft wakes up - level 1
Scientists send a spacecraft probe to space. This is in November, 2014.
The probe lands on a comet. The probe gets information. It gets power from sunlight. It runs out of power. It stops in a shadow. Now, it cannot get power. It stops sending information to the scientists.
Now, the comet flies closer to the sun. The shadow on the comet moves. The probe is in sunlight. It gets power again. It sends information to scientists again.
Difficult words: scientist (a person who studies a lot to learn about our world or space), probe (an electronic thing we use to get information from far away), comet (an icy rock that is flying in space).
