WASHINGTON — Sally Ride, who blazed trails into orbit as the first American woman in space, died Monday of pancreatic cancer. She was 61.

Ride died at her home in the San Diego suburb of La Jolla, said Terry McEntee, a spokeswoman for her company, Sally Ride Science. She was a private person and the details of her illness were kept to just a few people, she said.

Ride rode into space on the space shuttle Challenger in 1983 when she was 32. After her flight, more than 42 other American women flew in space, NASA said.
