Past, Present, and Future of Closed Human Life Support Ecosystems - A Review
(47th International Conference on Environmental Systems, 2017-07-16)
During the development of human space exploration, the idea of simulating the Earth’s biosphere to provide human life support led to the convergence of space biology and the field of ecology to develop closed manmade ...
A Method for Determining Body Weight Replacement Load during Squat Exercise in Weightlessness
(47th International Conference on Environmental Systems, 2017-07-16)
Studies on Astronauts in Mir space station has confirmed a loss of 1-2% in bone mass density for each month.They are prone to lose as much as 20% of their bone strength in their lower body which includes pelvis, hip bone, ...
Smart Sample Concentration System for Microbial Monitoring of Potable Water in the International Space Station
(47th International Conference on Environmental Systems, 2017-07-16)
The International Space Station (ISS) Water Processor Assembly requires routine microbial monitoring to ensure the safety of flight crews. Existing microbial detection methods are culture-based – posing a health risk in ...
Numerical Method to Simulate the Performance of Microgravity Membrane Gas-Liquid Separator
(47th International Conference on Environmental Systems, 2017-07-16)
Microgravity membrane gas-liquid separation technology is one of the key technologies of environmental control and life-support system, and the effective simulation of gas-liquid two-phase flow is an important method to ...
Thermal Design of HTV Small Re-entry Capsule
(47th International Conference on Environmental Systems, 2017-07-16)
JAXA is developing the HTV small re-entry capsule (HSRC) with a diameter of 0.84 meters aiming for experimental sample returning from the International Space Station also for basic technology demonstration of a re-entry ...
Thermal Performance of Oscillating Heat Pipe with Heat Switch Function for Lunar Mission
(47th International Conference on Environmental Systems, 2017-07-16)
The heat switch function of Oscillating Heat Pipes (OHP) with temperature controlled reservoir was experimentally investigated. Heat switch function of the OHP was hoped to use for a lunar rover or planetary observation ...
Life Support Multidimensional Assessment Criteria
(47th International Conference on Environmental Systems, 2017-07-16)
The primary evaluation scheme for comparison of life support systems is Equivalent System Mass (ESM). ESM can be used to identify the most efficient or least costly-to-launch option when selecting a solution from a group ...
Transient Mathematical Modeling of a Reservoir Controlled Loop Heat Pipe
(47th International Conference on Environmental Systems, 2017-07-16)
In this paper, a mathematical model of a loop heat pipe attached with thermoelectric converter was developed to simulate the transient behavior of actively controlled loop heat pipe radiator system. In this study, the ...
Numerical Analysis of the Effects of the Overboard Vent on Spacecraft
(47th International Conference on Environmental Systems, 2017-07-16)
During the operation of manned spacecraft, the pressure relief of the cabin is inevitable when pressure imbalance, fire or atmospheric pollution occur. Process of venting through the nozzle will generate distinct counterforce ...
Stiffness Equations of Astronauts EVA Glove (Orlan-DM)
(47th International Conference on Environmental Systems, 2017-07-16)
The Extravehicular Activity (EVA) Glove is one of the most important parts of an astronaut’s spacesuit. Bulk and stiffness of this glove cause many problems for astronauts such as dexterity reduction, increase of fatigue ...
