Analysis of Skeletal Muscle Metrics as Predictors of Functional Task Performance : EORS_FOI

Mon, 23 Nov 2009 23:23:44 GMT

OBJECTIVES:
Space flight induces a host of physiological changes that have harmful effects on human function in normal gravity. Upon entry into a gravitational environment, astronauts must cope with impairments in strength, balance, and the ability to ambulate. Although scientific investigations have begun to explain the underlying physiological mechanisms of these changes; the corre ...

Analysis of Volatile Organic Compounds on Mir Station : 9401666

Mon, 23 Nov 2009 23:23:44 GMT

OBJECTIVES:
With long-term space habitation quickly becoming a reality, the need for development of more advanced life support systems has become a priority. One drawback of current life support systems is the lack of real-time, on-site monitoring of the changing concentrations of volatile organic compounds (VOCs) present in the living environment. Applications of this technology extend far ...

Cardiovascular and Cerebrovascular Control on Return from International Space Station (CCISS) : E117

Mon, 23 Nov 2009 23:23:44 GMT

OBJECTIVES:
The ability to maintain arterial blood pressure and brain blood flow immediately on return to Earth after prolonged spaceflight is one of the most critical factors for crew health and safety. Although the heart rate component of the arterial baroreflex is impaired on return from space, this is not in itself a critical issue as crewmembers who are about to faint normally hav ...

Soft Contact Lens Application Test : DSO 427

Mon, 23 Nov 2009 23:23:44 GMT

OBJECTIVES:
The objective of this experiment was to determine the effectiveness of a method of application and fixation of specially marked contact lenses to the eyes during orbital flight.

Intraocular Pressure : DSO 425

Mon, 23 Nov 2009 23:23:44 GMT
OBJECTIVES:
The objective of this experiment was to determine if intraocular pressure increases with the anatomical changes experienced in orbital flight.

Study of In-flight Fluid Changes : DSO 423

Mon, 23 Nov 2009 23:23:44 GMT
OBJECTIVES:
The objective of the experiment was to assess the redistribution of fluid volumes including losses and changes in composition and pressure as influenced by the loss of hydrostatic forces during space flight.

Eye-Hand Coordination : DSO 418

Mon, 23 Nov 2009 23:23:44 GMT
OBJECTIVES:
The objective of this experiment was to evaluate changes in the perception of motion levels in crewmembers during space flight and immediately postflight.

Assessment of Endurance Capacity by Gas Exchange and Heart Rate Kinetics During Physical Training : EKE

Mon, 23 Nov 2009 23:23:44 GMT
The preservation of aerobic capacity is a major goal of exercise countermeasures during weightlessness. A widely used measurement for endurance capacity is maximal oxygen uptake (VO2 max) used during incremental levels exercise tests until exhaustion. A potential alternative method that will allow the reduction in the frequency of such tests, is to determine the dynamics of pulmonary oxygen uptak ...

Biomedical Analyses of Human Exposed to a Long Term Space Flight : Hair

Mon, 23 Nov 2009 23:23:44 GMT
OBJECTIVES:
The purpose of this experiment is to examine the effect of long-term space flight exposure on human hair. Hair from International Space Station (ISS) crewmembers will be collected in certain periods - preflight, in flight and postflight. In this experiment, the investigator plans two analyses on human hair from ISS crewmembers. First, nucleic acids (RNA and mitochondrial ...

Mycological Evaluation of Crew Exposure to ISS Ambient Air : Myco

Mon, 23 Nov 2009 23:23:44 GMT
OBJECTIVES:
It is well known that a living and working environment in the International Space Station (ISS) has been progressively contaminated by a number of microorganisms since the beginning of its construction. These microorganisms possibly may cause serious life-threatening diseases and allergies if the immune system is compromised. The objective of this study is to evaluate the r ...
