Question: Who as one of the seven crew members killed in the Space Shuttle "Challenger" disaster, who's death lead to the cancellation of the Teacher in Space Project ?

full_context: Document 1: STS-26: STS-26 was the 26th NASA Space Shuttle mission and the seventh flight of the orbiter "Discovery". The mission launched from Kennedy Space Center, Florida, on 29 September 1988, and landed four days later on 3 October. STS-26 was declared the "Return to Flight" mission, being the first mission after the Space Shuttle "Challenger" disaster of 28 January 1986. It was the first mission since STS-9 to use the original STS numbering system, the first to have all its crew members wear pressure suits for launch and landing since STS-4, and the first mission with bailout capacity since STS-4. STS-26 was also the first all-veteran crew mission since Apollo 11, with all of its crew members having flown at least one prior mission.
Document 2: Space Shuttle Challenger: Space Shuttle "Challenger" (Orbiter Vehicle Designation: OV-099) was the second orbiter of NASA's space shuttle program to be put into service following "Columbia". The shuttle was built by Rockwell International's Space Transportation Systems Division in Downey, California. Its maiden flight, STS-6, started on April 4, 1983. It launched and landed nine times before breaking apart 73 seconds into its tenth mission, STS-51-L, on January 28, 1986, resulting in the death of all seven crew members, including a civilian school teacher. It was the first of two shuttles to be destroyed in flight, the other being "Columbia" in 2003. The accident led to a two-and-a-half year grounding of the shuttle fleet; flights resumed in 1988 with STS-26 flown by "Discovery". "Challenger" itself was replaced by "Endeavour" which was built using structural spares ordered by NASA as part of the construction contracts for "Discovery" and "Atlantis".
Document 3: Christa McAuliffe: Sharon Christa McAuliffe (September 2, 1948 – January 28, 1986) was an American teacher from Concord, New Hampshire, and was one of the seven crew members killed in the Space Shuttle "Challenger" disaster.
Document 4: NASA's Story: NASA's Story is a documentary series by Dangerous Films for the BBC to commemorate 50 years since the formation of NASA. The series looks at NASA's early history, the triumphs and disasters, notably the Apollo 1 fire, through to the manned Moon missions and the Space Shuttle era. The show includes various interviews with astronauts and NASA personnel such as Chris Kraft, Jon Clark, Leroy Cain, Scott Carpenter, Neil Armstrong and Buzz Aldrin, both crew members of Apollo 11.
Document 5: STS-51-L: STS-51-L was the 25th flight of the American Space Shuttle program, and disastrous final mission of the Space Shuttle "Challenger", which lifted-off from Launch Complex 39-B, at the Kennedy Space Center in Florida, on January 28, 1986. The mission ended in catastrophic failure with the destruction of "Challenger", starting at 73 seconds after lift-off, and the death of all seven crew members. The Rogers Commission determined that the cause of the destruction was due to the failure of an O-ring seal on the starboard Solid Rocket Booster (SRB).
Document 6: Kalpana Chawla: Kalpana Chawla (March 17, 1962 – February 1, 2003) was an American astronaut and the first woman of Indian origin in space. She first flew on Space Shuttle Columbia in 1997 as a mission specialist and primary robotic arm operator. In 2003, Chawla was one of the seven crew members who died in the Space Shuttle "Columbia" disaster when the craft disintegrated during its re-entry into the Earth's atmosphere. Chawla is a recipient of the Congressional Space Medal of Honor.
Document 7: Ronald McNair: Ronald Erwin McNair (October 21, 1950 – January 28, 1986) was an American physicist and NASA astronaut. He died during the launch of the Space Shuttle "Challenger" on mission STS-51-L, where he was serving as the Mission Specialist. He is survived by his wife, Cheryl, and two children.
Document 8: Teacher Corps: Teacher Corps, whose correct title was the National Teacher Corps, was a program established by the United States Congress in the Higher Education Act of 1965 to improve elementary and secondary teaching in predominantly low-income areas. Individual Teacher Corps projects were developed by "institutions of higher education" (colleges or universities with a teacher-training program) in partnership with local school districts. The local director was a college professor, and courses specific to teaching inner city students and disadvantaged students were developed by the college and used in the master's level education program. Teams of interns under the supervision of master teachers worked in the district's schools to help carry out project goals. The purpose of the Teacher Corps was to train and retain teachers for disadvantaged school districts, who would work with the communities they served. Some of the interns became teachers in the communities they had worked in after the program ended. Others took jobs elsewhere teaching disadvantaged students, usually in their home states. Interns worked on community projects in addition to teaching. One of the Trenton, NJ community programs that continued for years after the program ended, was an annual carnival fundraiser to raise money for the Mott Elementary School library.
Document 9: STS-61-C: STS-61-C was the twenty-fourth mission of NASA's Space Shuttle program, and the seventh mission of Space Shuttle "Columbia". It was the first time that "Columbia", the first operational orbiter to be constructed, had flown since STS-9. The mission launched from Florida's Kennedy Space Center on 12 January 1986, and landed six days later on 18 January. STS-61-C's seven-person crew included the second African-American shuttle pilot, future NASA Administrator Charles Bolden, the first Costa Rican-born astronaut, Franklin Chang-Diaz, and the second sitting politician to fly in space, Representative Bill Nelson (D-FL). It was the last shuttle mission before the Space Shuttle "Challenger" disaster, which occurred just ten days after STS-61-C's landing.
Document 10: Project Mercury: Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. An early highlight of the Space Race, its goal was to put a man into Earth orbit and return him safely, ideally before the Soviet Union. Taken over from the U.S. Air Force by the newly created civilian space agency NASA, it conducted twenty unmanned developmental flights (some using animals), and six successful flights by astronauts. The program, which took its name from Roman mythology, cost $277 million in 1965 US dollars, and involved the work of 2 million people. The astronauts were collectively known as the "Mercury Seven", and each spacecraft was given a name ending with a "7" by its pilot.
Document 11: Challenger (1990 film): Challenger is a 1990 American disaster drama television film based on the events surrounding the Space Shuttle "Challenger" disaster. Its production was somewhat controversial as the families of the astronauts generally objected to it. The film concentrates on the safety inspections and arguments surrounding the O-rings that ultimately were blamed for the explosion of "Challenger". While doing this, it also aims to show the personal humanity of the seven crew members. Generally, the film supports the Space Shuttle program and the dedication of NASA personnel in general while criticizing NASA management.
Document 12: Educator Astronaut Project: The Educator Astronaut Project is a NASA program designed to educate students and spur excitement in math,science, and space exploration. It is a successor to the Teacher in Space Project of the 1980s that was cancelled after Christa McAuliffe died in the Space Shuttle "Challenger" disaster (STS-51-L). NASA halted the teachers project amid concerns surrounding the risk of sending civilians to space.
Document 13: NASA Astronaut Group 15: There were 23 astronauts in the NASA Astronaut Group 15. The group name for these astronaut trainees was originally "Slugs" because no group was convened the previous year and thus the group was slow in arriving. Group members adopted "The Flying Escargot" as their moniker, possibly in reference to two members of the group being from France, or in reference to the famous "flying escargot" scene in the movie "Pretty Woman". The group featured ten pilots, nine mission specialists, and four international mission specialist trainees.
Document 14: Canceled Apollo missions: Several planned missions of the Apollo manned Moon landing program of the 1960s and 1970s were canceled for a variety of reasons, including changes in technical direction, the Apollo 1 fire, hardware delays, and budget limitations. Immediately after the program achieved its primary objective in July 1969 with Apollo 11 to land men on the Moon and return them safely, nine more landing missions were planned, but the last three, Apollo 18, 19 and 20, were canceled.
Document 15: NASA Astronaut Group 3: Astronaut Group 3 was the third group of astronauts selected by NASA. Their selection was announced in October 1963. Fourteen astronauts made up Group 3. Four died in training accidents before they could fly in space. All of the surviving ten flew in the Apollo program; five also flew Gemini missions. Aldrin, Bean, Cernan and Scott walked on the Moon. They are the only ones of the first 19 NASA astronaut groups to have no members at all fly on the Space Shuttle.
