Ion beam sources for material processing in their working are no different from those required for space thrusters, ion implanters or for fusion experiments. They are scaled down versions of the devices earlier developed for space research. However, they ... see more

In the near future robotic systems will be playing an increasingly important role in space applications such as repairing, refuelling, re-orbiting spacecraft and cleaning up the increasing amount of space debris. Space Manipulator Systems (SMSs) are robot... see more

Hollow cathodes are electron sources used for the gas ionization and the beam neutralization in both ion and Hall effect thrusters (HETs). A reduction of power and propellant consumption from the cathode is particularly needed in small satellite applicati... see more

For satellite missions, thrusters have to be qualified in large vacuum vessels to simulate space environment. One caveat of these experiments is the possible  modification of the beam properties due to the interaction of the energetic ions with the&n... see more

Harnessing energy at micro-scale from high energy sources has gained significance in recent times for space propulsion and other applications. Conventional solid rocket propellants have advantages in terms of being efficient, compact and safe to handle, t... see more

Subject of this paper is the design of a space robotic mission to the asteroid 433 Eros. The mission aims to grab a boulder from its surface and transport it inside the Earth's Hill sphere. This kind of mission was chosen to develop a method of analysis o... see more

CubeSats provide a cost effective means to perform scientific and technological studies in space. Due to their affordability, CubeSat technologies have been diversely studied and developed by educational institutions, companies and space organizations all... see more

Liquid propellants are fast becoming attractive for pulsed plasma thrusters due to their high efficiency and low contamination issues. However, the complete plasma interaction and acceleration processes are still not very clear. Present paper develops a m... see more

Migration is associated with the search for a more permissive environment. By linking Paris as a place of attachment, the author sees that Paris in this case can be indicated as the “home” for Indonesian gays. The feeling of “full gay” is a feeling that t... see more
