MEMS
 MEMS stands for Micro Electro Mechanical
Systems
 It is the integration of electrical devices and
mechanical structures at the micrometer (10-6
m =
0.000001 m) scale.
 NASA has a very special interest in MEMS
technology.

TYPES OF MEMS
 Sensor - converts a nonelectrical input quantity (i.e.
pressure, temperature, acceleration) into an electrical
output quantity. Sensors are commonly encountered.
 Actuator - converts electrical input quantities into
non-electrical output quantities.
 Smart - MEMS combined with additional electronic
circuitry for control and processing information.

ROLE OF MEMS
 Command and control systems
 Inertial guidance systems
 Attitude determination and control systems
 Power systems
 Propulsion systems
 Thermal control systems
 Communication and radar systems
 Distributed semiautonomous
 Space environment sensors
 Interconnects and packaging

MEMS DEVICES
Micro heat pipe
Silicon satellites
 Micro satellites (1kg 100kg mass)
 Nano satellites ( 1g – 1kg mass)
 Pico satellites ( 1mg – 1g)
 Femi satellites (1 micro’s – 1mg mass)

SOLAR SAIL
 NASA is one of the organizations that have been
studying this amazing technology called solar
sails that will use the sun's power to send us into
deep space.
 Solar sails (also called light sails or photon sails) are
a form of spacecraft propulsion using the radiation
pressure (also called solar pressure) from stars to
push large ultra-thin mirrors to high speeds.
 A solar sail-powered spacecraft does not need
traditional propellant for power, because its
propellant is sunlight and the sun is its engine.

SOLAR SAIL HISTORY
 Nearly 400 years ago, as much of Europe was still
involved in naval exploration of the world, Johannes
Kepler proposed the idea of exploring the galaxy using
sails.
 The earliest reference to solar sailing was in Jules Verne's
1865 novel ”From the Earth to the Moon”, coming only
a year after Maxwell's equations were published.
 Scientists have since discovered that sunlight does exert
enough force to move objects.
 NASA has been experimenting with giant solar sails that
could be pushed through the cosmos by light.

ADVANTAGES OF SOLAR SAIL
 No requirement of fuel
Spacecraft work without a rocket engine
Keeps accelerating over almost unlimited distances
Quick acceleration

LIMITATIONS OF SOLAR SAIL
 Don't work well, if at all, in low Earth orbit below about
800 km altitude due to erosion or air drag
Physically large
Payload size is often small
Deploying solar sails is also highly challenging to date

CONCLUSION
 Micro-electromechanical systems and Solar Sail have
proved to be a part of the developing age especially in the
field of space and technology.
A solar sail is a spacecraft without a rocket engine. It is
pushed along directly by light particles from the Sun,
reflecting off its giant sails.
Solar sails will set new speed records for spacecraft
and will enable us to travel beyond our solar
system.
