NASA is sending a cool spacecraft called PACE into space.
PACE will help us understand why Earth is special and how it supports life.
It's going to study the oceans, the air, and the clouds in the sky.
PACE will use special tools to watch and learn about Earth for a really long time.
It will tell us about the air we breathe and things that affect our climate.
Right now, scientists are making sure PACE is super ready for its big trip into space.
PACE will ride into space on a powerful rocket called Falcon 9 from SpaceX.
PACE has cool tools to understand how Earth's weather and oceans work.
The information from PACE will help us take care of our planet better.
Everyone is very excited about PACE because it will teach us new things and make Earth even better!
