International Space Station

Photovoltaic (PV) solar cells, which convert incident solar radiation directly into electrical energy, today represent the most common power source for Earth-orbiting spacecraft, such as the International Space Station, where a photovoltaic engineering testbed (PET) is actually assembled on the express pallet. The solid-state photovoltaics, based on gallium arsenide, indium phosphide, or silicon, prove capable, even if to different extents and with... 

The prototype of the detector has already been tested in space on the space shuttle. The AMS will be placed on the International Space Station (ISS) orbiting Earth in the fall of 2003. One of the most important experiments will be the search for antimatter of a cosmological origin. 

Imagine that NASA has given you a ton of money to develop a mass sensor for the International Space Station. It will be used for monitoring the air quality inside the station. Which type of mass sensor could you NOT use QCM, SAW, cantilever (in bending), or cantilever (resonant mode) ... 

For closed-cycle applications, such as for spacecraft, submarines, or transportation vehicles, the combinations of lightweight, reasonable power density, and compact size are favorable features in comparison with equivalent-capacity battery-based systems. In the International Space Station, for example, both electricity and water are provided by fuel cells. Fuel cells have not only been used in space exploration, but also in submarines (because they generate no noise or vibration). They have also been used to recover the energy from methane that is generated by wastewater, by garbage dumps, and more recently in automobiles as an alternative to the IC engine. 

Our planet receives as much solar energy in 30-40 minutes as humankind uses in a year. Solar energy is the most abundant energy source on the planet. It is already being used as the energy source of space vehicles and space stations. (The energy source on the International Space Station is an acre-size solar collector receiving an insolation of 1.37 kW/m2.) The capacity of a collector is expressed in terms of its peak power production (wp). ... 

While concepts in scientific measurements and properties of matter were being addressed in their general chemistry course, students participated in a 2-week activity in the WDKA Space Science course where they designed and built a model of the International Space Station (ISS) adapted from an activity developed by the National Aeronautics and Space Administration (NASA).14 They researched the history, design, and facilities of the ISS as well as the nature of science missions on the ISS. They were then provided with a variety of...

Chapter 9, Disposal, Degradation, and Recycling, can be used for a class project for Earth Day. Students have sent projects on the effects of the environment on plastics out into space on the International Space Station. Classes can do a similar project on a smaller scale by studying the effects of the weather on some plastic samples kept outside the classroom window. 

My knowledge grew at Bend Research, Inc. under Harry Lonsdale, another membrane pioneer who was involved in the theoretical and practical side of membranes since the early 1960 s at Gulf General Atomic (predecessor of Fluid Systems, now Koch Membrane Systems), Alza, and later Bend Research, which he co-founded with Richard Baker. At Bend Research, I had the opportunity to develop novel membranes and membrane-based separation processes, including leading several membrane-based projects for water recovery and reuse aboard the International Space Station. 

The 260 million Pathfinder and the Mars rovers are sending streams of data from the Martian surface back to Earth. Meanwhile, the International Space Station has been bedeviled by a seemingly endless stream of accidents. The Mir space station, brought back to Earth and crashed into the ocean after 15 years in 2001, had several incidents where lives were at great risk, including a fire and a collision with a docking ship. The greatest measurable achievements in space have been made by the unmanned robotic vehicles and instruments.

Any use of novel responsive polymer components in space applications requires ground testing and ultimately space qualification to accommodate the complex LEO environment and better understand synergistic materials degradation. We have therefore participated in MISSE-6 (Materials International Space Station Experiment) with a combination of active and passive sample exposures that have been selected as a first flight experiment of piezoelectric polymers in LEO for space qualification. Two exposure conditions were available, the VUV backside and the VUV+AO ram direction of the MISSE assembly. Our experimental strategies for sample selection, exposure conditions and in-situ performance measurements are presented here.

In 1839, Sir William Robert Grove, a British lawyer and physicist, built the first fuel cell. More than 100 years later, fuel cells finally found a practical application—in space exploration. During short space missions, batteries can provide enough energy to keep the astronauts warm and to run electrical systems. But longer missions need energy for much longer periods of time, and fuel cells are better suited for this than batteries are. Today, fuel cells are critical to the space shuttle missions and to future missions on the international space station.
