The document summarizes the Mini-Magnetospheric Plasma Propulsion (M2P2) concept. M2P2 uses a magnetic field and plasma injected from a helium source to create an artificial magnetosphere around a spacecraft that interacts with solar wind particles to provide thrust. A prototype M2P2 system could accelerate a 100-200 kg spacecraft to velocities of 50-80 km/s using only 15-30 kg of propellant over 3 months. M2P2 offers potential advantages over conventional chemical rockets and solar sails by providing continuous thrust with less fuel and mass.

MINI MAGNETOSPHERIC PLASMA PROPULSION
INTRODUCTION • M2P2- Mini Magnetic Plasma Propulsion. • Also known as “Plasma Sail" • Concept proposed by the astrophysicist Robert Winglee • High thrust is imparted to the space craft
BASIC PRINCIPLE • Solar sail- Transfer of momentum from solar wind using a thin film attached to the space craft called solar sail. • Solar wind pushes it constantly • Space vehicles can be moved at similar speeds
BASIC PRINCIPLE - contd Solar sail
PREDECESSOR OF M2P2 – MAGNETIC SAIL • A loop of conducting wires create a magnetic field around a space vehicle • Magnetic field reflects the charged particles from the sun (solar wind) • The momentum impart by reflection provides thrust to the space craft
MINI MAGNETOSPHERIC PLASMA PROPULSION - MECHANISM • Advanced form of magnetic sail propulsion • Solar panel powers a solenoid and generates a magnetic field • Helium source injects plasma into magnetic field.
M2P2 MECHANISM - contd • Plasma is trapped in magnetic field lines. • Magnetic field expands – plasma grows • Field lines expands to a outward radius of 18-36 miles around the spacecraft • Interaction with solar wind increases tremendously
CREATING A MAGNETOSPHERE Magnetic field + plasma = Strong Solar Wind Coupling Plasma injection dn wr a o S i l
M2P2 PROTOTYPE • Main parts :- Solenoid : * Used for producing magnetic field * Encased in stainless steel against direct exposure to plasma. Helium plasma source Gas feed system * Provide constant gas supply against plasma leak
M2P2 PROTOTYPE copper housing coil connections
ARTISTS IMPRESSION OF A MINI-MAGNETOSPHERE DEPLOYED AROUND SPACECRAFT
MODEL PERFORMANCE For an 15- 30 kg amount of propellant the performance is: •Accelerated spacecraft mass :100-200 kg •Velocity attained : 50-80 km/s •Acceleration period : 3 months.
COMPARISONS  Theoretically 10 times faster than space shuttle (4.3 million miles/day vs. 430,000 miles/day)  Could overtake Pioneers 10 & 11 and Voyagers 1 & 2 (launched in the 1970s);  Will be the first manmade object to leave solar system
ADVANTAGES Provides constant force with less amount of fuel No new technology is used Lighter and less bulkier than sails No erosion of components –magnetic bubbles protects the spacecraft
ADVANTAGES - contd The magnetic bubble self adjusts to solar wind as the vehicle travels away from sun Magnetosphere protects crew from harmful radiations Cost efficient
LIMITATIONS • Requires good superconducting wires to maintain the magnetic field intact.
