Bioastronautics—at the interface of biology, medicine, engineering and space research—challenges the state of the art in human protection and integrative physiology.

An astronaut who travels for long periods far from earth is affected by weightlessness, space radiation and psychological stress, and is utterly dependent on artificial life-support. Bones and muscles, cardiovascular regulation and sensory-motor control depend on gravity on earth and require protection during space flight. The challenge of bioastronautics is to protect the astronaut during and following long flights, and to provide air, water, food, and telemedicine, while dealing with the scientific issues of gravitational biology.

HST’s PhD Program in Bioastronautics prepares graduate students in space life sciences, aerospace engineering and space medicine for a broad range of possible career opportunities. The program provides its students with a combination of science and engineering coursework, clinical experiences, space-related research apprenticeships, and thesis research options at MIT, Harvard, and associated hospitals.

Academic Program

MEMP students who wish to affiliate with the Bioastronautics program must complete the following requirements in addition to the regular MEMP curriculum.

  • HST 515J Aerospace Biomedical and Life Support Engineering 
  • 16.453 Human Factors Engineering 
  • 16.89J Space Systems Engineering OR 16.851 Satellite Engineering

And at least one subject from the following list: 

  • HST 560J Radiation Biophysics 
  • HST 971J Strategic Decision Making in Biomedical Enterprise 
  • HST 020 Musculoskeletal Pathophysiology
  • 2.183J Biomechanics and Neural Control of Movement

Students in the program may optionally complete a summer apprenticeship at a NASA Center. Students also have the option (space permitting) to use either the Aerospace Medicine Clerkship at Johnson Space Center or the Space Medicine Short Course at University of Texas Medical Branch to fulfill the elective portion of the Introduction to Clinical Medicine and Medical Engineering (HST202).

Applications to the PhD Program in Bioastronautics should be made as part of an application to MEMP and are due by December 1 *CHANGE* of each year for the following September.  

Applicants to MEMP/Bioastronautics must meet the general requirements for MEMP applicants, which include a baccalaureate degree in engineering or physical science and demonstration of a sustained interest in applications of engineering and physical science to biology or medicine through courses, research, and/or work experience. In addition, candidates for MEMP/Bioastronautics must have completed at least a bachelor's degree or substantial minor in a related area such as aeronautics and astronautics, mechanical engineering, electrical engineering, biomedical engineering, mathematics, or physics, as well as coursework and/or research experiences demonstrating a sustained interest in space life sciences.

Please contact hst-phd-admissions [at] for information about applying to MEMP for information regarding the Bioastronautics academic program.
