Nasa mathematician Katherine Johnson, who helped launch the initially American into orbit around the Earth, has died at the age of 101.
Nasa, which describes Ms Johnson as one of its “most influential figures”, announced her demise on Twitter.
“Today, we celebrate her 101 decades of lifestyle and honor her legacy of excellence that broke down racial and social obstacles,” it wrote.
Ms Johnson’s position at Nasa was highlighted in the film Concealed Figures.
The 2016 movie tells the tale of African-American ladies whose maths abilities served place a US astronaut into orbit in the 1960s.
