Sally Ride (May 26, 1951 – July 23, 2012) was an American astronaut and physicist. Born in Los Angeles, she joined NASA in 1978, and in 1983 became the first American woman and the third woman to fly in space, after cosmonauts Valentina Tereshkova in 1963 and Svetlana Savitskaya in 1982. She was the youngest American astronaut to have flown in space, having done so at the age of 32. She was selected as a mission specialist astronaut with NASA Astronaut Group 8, the first class of NASA astronauts to include women. After completing her training in 1979, she served as the ground-based capsule communicator (CapCom) for the second and third Space Shuttle flights and helped develop the Space Shuttle’s robotic arm. In June 1983, she flew in space on the Space Shuttle Challenger on the STS-7 mission. The mission deployed two communications satellites and the first Shuttle pallet satellite (SPAS-1). Ride operated the robotic arm to deploy and retrieve SPAS-1. Her second space flight was the STS-41-G mission in 1984, also on board Challenger. She spent a total of more than 343 hours in space. She left NASA in 1987. We celebrate her 74^th birthday with an image of a Lego figure made in her honour …
