Deep Space Travel for Humans

Many theoretical ideas

• Aclubierre Drive
• Solar Sail
• Magnetic Sail
• Worm Hole

4
Practicality

• Methods mentioned are impractical, impossible by
  known standards, and we dont even know if there
  even feasible.
• AlcubierreMake this, and youll be the greatest
  scientist ever
• WormholeThrow a can of tuna into Large Hadron
  Collider? I wish.
• Magnetic and Solar Sails Have constant energy
  source (Solar flares and photons). What
  materials can be used?
• No funding, not enough energy/technology, and
  lack of materials.

Nowdays we use

Feasable Ideas

• Lets focus on what is actually a good idea, and
  will not let us go over our heads

7
Nuclear Energy

• Two types of energy gained from nuclear
  reactions.
• Fissure split an atom into smaller parts,
  releasing huge energies. Have used fissure to
  create efficient energy
• Fusioncombining light elements to create heavier
  elements. Have NOT used fusion to create
  efficient energy. A lot of energy is still
  required to make fusion. More powerful than
  fission

Types of Nuclear Propulsion systems

Types of nuclear propulsion systems

• Nuclear ElectricIonizes fuel instead of heating
  it up, and sends it through an electric field.
  Basically same idea as Nuclear Thermal with
  chemical energy, but uses electrical
• Electric Propulsion with nuclear reactor
• Satellites nowadays use Electrical propulsion.

• Explosive Propulsion
• Nuclear Thermal Propulsion

Chemical Rocket vs Nuclear Rocket
12
Issues with Nuclear Propulsion

• Public view
• Radiation exposure
• In some methods, lack of constant propulsion
• Methods of utilization
• Trouble getting nuclear energy for use into
  space.
• Preferred it be fusion

13
Plasma Rockets

• Plasma instead of liquid hydrogen
• For the curious, plasmaionized gas
• Many see it as a precursor to Nuclear Fusion
• VASMIR
• Electrically charged plasma rocket,
• Gets energy from heating plasma, then releases it
  as electrical energy (electrical propulsion)
• Converts Plasma to electrical energy using
  magnetic fields
• Renewable since it uses gases in outer space.

14
Three Steps of Vasimr

• Gas is ionized
• Add energy, usually by adding voltage or heat
• Ion cyclotron heating
• Heats up electrons in a tokamak
• Heating of gas turns to propulsion
• Energy expelled turns to thrust for rocket

Pictures

• Tokamak
• Ion cyclotron heating

16
Miscellanous

• Problems with plamsa rockets
• Technology, funding, and public view.
• Questions to physicists
• Materials used for making kinds of ships?
• Radiation protection? Most likely aluminum
  composite.
• When or who will create a fusion reactor with
  more output energy than input? Almost at a
  break-even
