Wear, 1962
Abstract Operation of mechanical devices beyond the earth's atmosphere presents a number of peculiar problems to the lubrication engineer. The environment includes meteroids, weightlessness, various forms of radiant energy, temperature extremes, and ultrahigh vacuum. From a practical viewpoint, the high vacuum provides the most interesting challenges

Validation of design for space launch vehicles
1993 Proceedings Real-Time Systems Symposium, 2002Interactions between fault tolerance and real-time requirements make the design of fault tolerant avionics for launch vehicles a challenge due to the necessity to handle time constrained execution of asynchronous events concurrently with potential faults. Results of designed experiments run on a prototype fault tolerant network are described. The shape

Telemetry Data Reduction for Space Vehicles
IEEE Transactions on Aerospace, 1964Real-time automatic digital data reduction and evaluation have been used at Lockheed Missiles and Space Company for the last year and a half. The advantages of this method over analog-record methods are clearly demonstrated. The computer programming-software is described which controls the system.

On spacing policies for highway vehicle automation
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000This paper develops a framework for the design and evaluation of spacing policies for adaptive cruise control. Spacing policies are evaluated from the point of view of string stability, traffic flow stability and traffic flow capacity. The standard constant time-gap spacing policy can guarantee string stability but is shown to suffer from poor traffic ...

Huge object manipulation in space by vehicles
IEEE International Workshop on Intelligent Robots and Systems, Towards a New Frontier of Applications, 2002Studies about space robots have assumed a relatively small object as a manipulated target. But in space a target object can be relatively huge, for example the spacecraft, the space station, the solar power satellite, etc. In these cases, manipulation by several vehicles which have a thrust engine is superior than that by arms mounted on the ...

Smart Vehicle Spaces [Guest Editorial]
IEEE Pervasive Computing, 2016During the past few decades, cars have transformed from being relatively mundane spaces underpinned by mechanical platforms with sprinklings of electronics into complex computational platforms. As a result of this continual development and the smart spaces it has enabled, we are now seeing the signs of tectonic shifts in car-related experiences ...

As stated, LEO space vehicles are more representative of the immediate growth in the development and deployment of space systems. Their comparative simplicity also allows for easier analogy and framing for cyber discussions around space systems in general. There are, however, many other types of space vehicles in and beyond Earth’s orbit. These systems
