NASA Astronaut Group 9 was a group of 19 NASA astronauts announced on May 29, 1980, and completed their training by 1981. This group was selected to supplement the 35 astronauts that had been selected in 1978, and marked the first time that non-Americans were trained as mission specialists with the selections of ESA astronauts Claude Nicollier and Wubbo Ockels. In keeping with the previous group, astronaut candidates were divided into pilots and mission specialists, with eight pilots, eleven mission specialists, and two international mission specialists within the group.
NASA Astronaut Group 10 was a group of 17 astronauts that were announced on May 23, 1984 and consisted of seven pilots and ten mission specialists. Although selected in 1984, no member of the group would fly until 1988 due to the Challenger disaster and the resulting grounding of the Space Shuttle fleet.
