James P. Bagian

James P. Bagian is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand James P. Bagian rather than just read about it. In short: James Philip Bagian (born February 22, 1952), is an American physician, engineer, and former NASA astronaut of Armenian descent. During his career as an astronaut, he logged 337 hours of space-flight, over two missions, STS-29 (in 1989) and STS-40 (in 1991).

Key takeaways

  • James P. Bagian belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect James P. Bagian to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of James P. Bagian from memory before moving on to harder problems.

Reference excerpt

James Philip Bagian (born February 22, 1952), is an American physician, engineer, and former NASA astronaut of Armenian descent. During his career as an astronaut, he logged 337 hours of space-flight, over two missions, STS-29 (in 1989) and STS-40 (in 1991). After leaving NASA in 1995, Bagian was elected as a member of the National Academy of Medicine. He was also elected as a member of the National Academy of Engineering in 2000 for the integration of engineering and medical knowledge in applications for aerospace systems, environmental technology, and patient safety. Bagian is currently the Director of the Center for Healthcare Engineering and Patient Safety at the University of Michigan. Bagian is the only person of Armenian descent to have been in space.

Education Bagian graduated from Central High School in Philadelphia, Pennsylvania, in 1969; received a Bachelor of Science degree in mechanical engineering from Drexel University in 1973, graduating first in his class, and a Doctor of Medicine degree from Thomas Jefferson University in 1977, where he was a member of Alpha Omega Alpha.

Experience Bagian worked as a process engineer for the 3M Company in Bristol, Pennsylvania, in 1973, and later as a mechanical engineer at the U.S. Naval Air Test Center at Patuxent River, Maryland, from 1976 to 1978, and at the same time, pursued studies for his medical degree. Upon graduating from Thomas Jefferson University in 1977, Bagian completed one year of general surgery residency with the Geisinger Medical Center in Danville, Pennsylvania. He subsequently went to work as a flight surgeon and research medical officer at the Lyndon B. Johnson Space Center in 1978, while concurrently completing studies at the USAF School of Aerospace Medicine in San Antonio, Texas, where he graduated first in his flight surgeons class. He was completing a residency in anesthesiology at the University of Pennsylvania when notified of his selection by NASA for the astronaut candidate program. Bagian received his Professional Engineers Certification in 1986 and was board-certified in aerospace medicine by the American College of Preventive Medicine in 1987. Since 1981, Bagian has been active in the mountain rescue community and has served as a member of the Denali Medical Research Project on Denali. He has been a snow-and-ice rescue techniques instructor on Mount Hood during this period. Bagian is a colonel in the U.S. Air Force Reserve and is the pararescue flight surgeon for the 939th Air Rescue Wing. He is a USAF-qualified freefall parachutist, holds a private pilot's license and has logged over 1,500 hours flying time in propeller and jet aircraft, helicopters, and gliders.

NASA experience Bagian became a NASA astronaut in July 1980. He took part in both the planning and provision of emergency medical and rescue support for the first six Shuttle flights. He served as the Astronaut Office coordinator for Space Shuttle payload software and crew equipment, as well as supporting the development of a variety of payloads and participating in the verification of Space Shuttle flight software. In 1986, Bagian served as an investigator for the 51-L accident board. He was responsible for the development program and implementation of the pressure suit used for crew escape and various other crew survival equipment to be used on future Shuttle missions, and is in charge of Shuttle search and rescue planning and implementation for the Astronaut Office. Bagian was a member of the NASA Headquarters Research Animal Holding Facility Review Board. He has authored numerous scientific papers in the fields of human factors, environmental and aerospace medicine. A veteran of two space flights (STS-29 in 1989 and STS-40 in 1991), Bagian has logged over 337 hours in space. In 2003 Bagian served as the Chief Flight Surgeon and Medical Consultant for the Columbia Accident Investigation Board and currently serves as a member of the NASA Aerospace Safety Advisory Panel.

STS-29

Bagian first flew on the crew of STS-29, which launched from Kennedy Space Center, Florida, aboard the Orbiter Discovery, on March 13, 1989. During this highly successful five-day mission, the crew deployed a Tracking and Data Relay Satellite and performed numerous secondary experiments, including a Space Station "heat pipe" radiator experiment, two student experiments, a protein crystal growth experiment, and a chromosome and plant cell division experiment. Bagian was the principal investigator and performed Detailed Supplementary Objective 470 which described, by the use of transcranial Doppler, the changes of cerebral blood flow and its relationship to Space Adaptation Syndrome (SAS) and Space Motion Sickness (SMS). Bagian was the first person to treat SMS with the drug Phenergan by intramuscular injection. This represented the first successful treatment regimen for SMS and has now been adopted by NASA as the standard of care for the control of SMS in Shuttle crews and is routinely used. In addition, the crew took over 3,000 photographs of the Earth using several types of cameras, including the IMAX 70 mm movie camera. Mission duration was 80 orbits and concluded with a landing at Edwards Air Force Base, California, on March 18, 1989. With the completion of this mission, he logged over 119 hours in space.

Worked examples

Example 1 — a first encounter with James P. Bagian

Start with the simplest possible case. Write down what James P. Bagian claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to James P. Bagian before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about James P. Bagian ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of James P. Bagian

In research
James P. Bagian appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses James P. Bagian in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
James P. Bagian is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, American people of Armenian descent, Armenian astronomers, so understanding it makes those chapters shorter.
In everyday life
Look for James P. Bagian outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
