Pioneering African-American Nasa mathematician Katherine Johnson has died at the age of 101.

Axar.az informs citing foreign media.

Nasa announced her death on Twitter, saying it was celebrating her life and honouring "her legacy of excellence that broke down racial and social barriers".

Ms Johnson calculated rocket trajectories and Earth orbits for Nasa's early space missions.

She was portrayed in the 2016 Oscar-nominated film Hidden Figures.

The film tells the story of African-American women whose maths skills helped put US astronaut John Glenn into orbit around the Earth in 1962. Ms Johnson verified the calculations made by new electronic computers before his flight.
