A tribute to the Class of 2020 will be headed into space along with astronauts Bob Behnken and Doug Hurley.
Ahead of the historic launch, SpaceX and NASA solicited photos from students all over the world in kindergarten through grad school. The pictures were used to create a mosaic of the Earth.
The mosaic was printed out and will fly aboard SpaceX's Crew Dragon.
You can view the mosaic on the SpaceX website. It allows you to zoom in and view individual photos, as well as search for students from specific schools.
The launch was scheduled to take place Wednesday but was scrubbed due to weather.
When they do launch, the astronauts will be traveling to the International Space Station.
It will be the first time in nine years that American astronauts will lift off from their home soil and it will be the first time ever that a rocket developed by a private company will carry U.S. astronauts into space.
