Space shuttle flight

C04-0151. The CO2 exhaled by astronauts must be removed from the spacecraft atmosphere. One way to do this is with solid LiOH C02(g) + 2 LiOH(,5 ) Li2 C03(,3 ) + H2 0(/) The CO2 output of an astronaut is about 1.0 kg/day. What is the minimum mass of LiOH required for a six-day space shuttle flight involving five astronauts ...

Voorhees s experimental study of low-volume-fraction-solid liquid+solid Pb-Sn mixtures carried out under microgravity conditions during a space shuttle flight enabled a wider range of solid-phase volume fractions to be studied without significant influence of buoyancy (flotation and sedimentation) effects [13]. The rate of approach to the steady-state particle-size distribution in 0.1-0.2 volume-fraction... 

Alkaline fuel cells (AFCs) were the first type of fuel cell to be widely used in space exploration applications-for example, in NASA s Apollo and space shuttle flights. Figure 1.8 shows a schematic of an AFC stmcture. AFCs use H2 and 02 as fuel and oxidant, respectively. The electrolyte is a concentrated KOH solution absorbed into an asbestos matrix. The temperature for AFCs ranges from 100-250°C and the efficiency can be > 60%. OH ions are transported through the electrolyte from cathode to anode. The reactions are as follows ... 

Space Shuttle flights also brought new dimensions to the observations of the metals, especially to the study of Mg" ". A typical spectrum of the thermospheric dayglow observed from the Shuttle is shown in Fig. 6 and shows the prominence of the Mg " resonance line as well as the lines of other metals. The spectrograph was aimed at a tangent height of 136 km. Particularly exciting and important for the development of adequate models has been the recent simultaneous observations of Mg and Mg" ". These... 

As a result of experiments originally conducted on Apollo 16 (34), commercial electrophoretic efforts have been undertaken on space shuttle flights (45,46). The apparatus involved employs free flow electrophoresis of a protein mixture for the purification and recovery of a very high valued product. The process itself is proprietary. However, data and models are available from earlier flights and other experiments (34,47,48).

The principle of modularity leads us to examine how the vocabulary of safety may itself be composed of sub-vocabularies, each with its own independent logic. One important example I identified is the vocabulary of risk assessment, which developed independently of the operational language that guides most of the space shuttle flight operations.

In addition to their use as described above, smaller versions of NaS batteries are excellent candidates for use on satellites and space vehicles. When satellites are on the dark side of Earth, they need powerful batteries to continue to run normally solar-powered communication and guidance systems. Relatively inexpensive, lightweight, and durable NaS batteries are excellent candidates for this type of application. They have already been tested on space shuttle flights and operated successfully. 

Implementation of active and passive redundancy can be dynamic. Notably in the case of a space shuttle, flight hazards can be controlled by rapidly changing the mission, as shown in Figure 1.35. The five processing units linked to the flight functions can be reconfigured.
