Carlos Ortiz Longo
Carlos Ortiz Longo (born August 18, 1962) is a Puerto Rican NASA Aerospace Engineer at the Johnson Space Center, and Commercial Pilot, with over 30 years expertise in Thermal Analysis, Thermal Design, Atmospheric Thermal Protection Systems, Materials Engineering, Mechanical Behavior of High Temperature Structural Ceramics, Mechanical Testing of Materials, Structural Mechanics, Astronaut Crew Health Care Systems, Project Management, and System Management. He also has 20 years experience as a General Aviation, and Commercial and Corporate pilot.
Ortiz Longo was born in San Juan, Puerto Rico where he received both his primary and secondary education. As a child his creative imagination was encouraged by both his parents. His father, Dr. Ortiz, a medical physician, was very influential in his life. He was always fascinated with his son's curiosity and encouraged him to find out how things worked even if it meant taking them apart and putting them back together again.
In 1980, Ortiz Longo enrolled in the University of Puerto Rico at Mayaguez school of engineering. During his third year, while studying mechanical engineering, he came upon an advertisement in his school stating that officials from NASA would be visiting and conducting interviews at the campus. Ortiz Longo responded to the ad and went to the interview. NASA accepted him and offered a him part-time job in the continental United States.
In 1983, he moved to United States and joined NASA as a cooperative education student. He helped train astronauts for the first Spacelab mission which was carried aloft in the Space Shuttle Columbia's payload bay during STS-9.
Earned his Bachelor of Science in Mechanical Engineering from the University of Puerto Rico at Mayagüez in 1984. Inducted to the Engineering Honor Society, Tau Beta Pi. Earned his Master of Science in Material Science and Engineering from the Cullen College of Engineering in 1993. In 1996, Ortiz Longo was part of the Astronaut Selection Program group of 123 finalists (from a pool of 2451 qualified applicants), that interviewed at the Johnson Space Center to become part of Astronaut Class 16. This year, he was also named Space Shuttle Division Chief Engineer for structures, mechanics and materials.
Earned his Doctorate Degree in Material Science and Engineering from the Cullen College of Engineering in 2000. In 2003 he began supporting the Space Station Program as System Manager for the Crew Health Care System (CHeCS).
Dr. Ortiz Longo is also a commercial pilot. He is an avid flyer of vintage and experimental aircraft, including: Boeing Stearman, North American T-6 Texan, Russian Yakovlev Yak-50 (1975) and Yakovlev Yak-52, Boeing B-17, North American B-25, Max Holste Broussard, Wilga PZL-104, North American T-28 Trojan, amongst others. He also flies corporate jets, including the Gulfstream IV, Beechcraft Hawker (British Aerospace 125), Cessna Citation V, and the Embraer Phenom 300.
