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.
