... “intellectual grandfather” of many small satellites that are built by students at colleges and universities for launch today. The heritage characteristics still found in student experimental small satellite projects are: (i) compact size ... controlled active de-orbit system. Yet another option that has evolved has been for student experimental satellites to include light weight passive de-orbit systems such as end of life balloons, sails ...

... through the use of “national technical means”, or spy satellites. Satellites supply a daily service, with applications as diverse as cartography, fire monitoring, ocean current mapping, iceberg tracking, urban planning, renewable and nonrenewable ... Sun or an active transmitter on a satellite interacts with the atmosphere, land, ocean, or vegetation in different ways. Some energy is reflected back to the satellite, some is scattered, and the target ...

... . Other satellites look at the cloud patterns and temperatures and give us our weather and hurricane forecasts days in advance. Still others help us search for minerals, or study the oceans, or study the ozone layer which protects us from sunburn. Many long distance phone calls go by satellite, and war reporters send their news back from the battle zones via satellite ...

... study more in detail the collision risk between the SPOT satellites and the catalogued space debris. The main objectives of this experimental procedure were to better assess the risk and to highlight ... be carried out, giving in particular statistical information concerning the fly-by distances between the satellites and the objects in space. Finally the need for new theoretical studies was evidenced together ...

... Life on Earth exists, and may well have begun, at hot springs on the deep ocean floor. This life is supported by chemical energy rather than sunlight. It is not unreasonable ... hot springs at the rock-ice interface on large tidally-heated bodies such as the satellites of the outer planets. Of all the possible candidate worlds, Europa is the likeliest to ...

... , agility '''JBIS Reference Code ''' - 2004.57.318 '''Number of Pages''' - 7 Abstract This paper presents experimental results on the performance of a Control Moment Gyroscope (CMG) cluster. The goal is to design a CMG cluster for 3-axis control for agile microsatellites. The experimental data are compared with simulation (theoretical) results and both are used to verify the principles ...
