SMART- 1 EPS Flight Equipment
The Electric Propulsion Subsystem (EPS) provides primary propulsion onboard of the ESA SMART-1 spacecraft, which is the
first of the Small Missions for Advanced Research and Technology (SMART) in the ESA Horizon 2000 plan. The EPS is
supposed to demonstrate the use of electric propulsion as a primary source and under variable input power conditions.
The EPS is composed primarily of a Xenon storage tank, a pressure regulation unit, a flow control unit, a power processing
and control unit, propellant pipework, electrical harnesses, and electric thruster(s). The thrusters that can either be gridded ion
thruster(s) or a Hall plasma thruster(s), The thruster alignment mechanism is not included and is under the direct responsibility
of the SMART-1 Prime Contractor. In addition to the delivery of the SMART-1 EPS hardware, the contract includes also the
assembly, the integration, the verification, on the spacecraft, as well as the support to the Prime Contractor for the
environmental testing and flight operation support. This procurement is to be placed in one single stage starting from the
development phase up to the flight phase. The design definition study phase has been performed at ESA and has been used
to prepare the EPS technical specifications, which are part of the Request For Proposal (RFP). The SMART-1 design is based
largely on existing electric propulsion system, currently developed for North-South station keeping of Geostationary
telecommunication satellites. The development required is therefore limited to the adaptation of an existing system to the
SMART-1 needs as specified in the technical specification.
The activity was initiated in the frame of a previous TRP workplan. The current activity will cover an additional work package.

Title:
Investigation Into MEMS - MEOMS Packaging
Micro Electronic Mechanical Systems (MEMS), commonly called micro-machines, are micron-sized devices that can sense or
manipulate the physical world. MEMS are actual mechanical systems that are created via a process called micro machining.
Due to the growing demand of miniaturised components, manufacturers are being forced to come up with technological
breakthroughs in order to satisfy this demand. MEMS are a combination of mechanical and electrical features in a very small
package.
MEMS are used in medicine, transportation, industrial and consumer products, and most commonly for accelerometers in
automotive air bags. The rapid increase in demand for communications has promoted the development of optical switching
applications where high-speed broadband networks, expanding service capabilities, are needed, thus leading to the Micro
Optical Electronic Machines (MOEMs). These need both improved optical and electrical interfaces as well as more
time-efficient ways to make fiber connections. This is driving the need for new packaging solutions. Protection is a key
element in packaging MEMS and MOEMs because corrosion, moisture, and debris can prevent the devices from working.
Each device must be hermetically sealed in order to prevent the devices from becoming contaminated. The proposed activity
will investigate the MEMS – MEOMS Packaging technologies.
