This beautiful picture book tells the story of two scientists who worked together side by side to send humans into space.

Mary Jackson was super smart. She loved maths and science, and she loved to learn. When Mary got a job at NASA, it was a dream come true! But this was a time when Black people were segregated from white people, and Mary had to fight hard for every opportunity.

In 1953, Mary started working alongside Kaz Czarnecki. They soon realised how much they could share and teach each other. The two were from completely different backgrounds, but it didn't matter at all – they had so much in common.

This was the beginning of a friendship that lasted for decades. Together, they worked on amazing experiments and achieved incredible things, like working to land astronauts on the moon.

Friends Change the World is a series of picture books that celebrates the power of friendship. From musical greats to sports champions, scientists and explorers to artists and activists, these are the true stories of real friends who achieved amazing things. Whether best friends since school or thrown together by a chance encounter, they supported and inspired each other to make their shared dreams come true. This charming series shows 4- to 7-year-olds how togetherness, respect and friendship can make the world a better place.
