Engineering Design

Engineering Design

• Course Objective
• To design and construct a scale model of a lunar
  colony by following the engineering design
  process

2
Background

• By 2020 the U.S. is planning to have established
  a lunar colony.
• By 2040, humans on Mars.
• This challenge was presented to the public by
  President G.W. Bush on January 14, 2004.

3
Background

• The President committed the United States to a
  long-term human and robotic program to explore
  the solar system, starting with a return to the
  Moon that will ultimately enable future
  exploration of Mars and other destinations.
• The President's vision affirms our Nation's
  commitment to manned space exploration. It gives
  NASA a new focus and clear objectives.
• It must be affordable and sustainable while
  maintaining the highest levels of safety.

Why Explore?

• Space Technology Affects the Lives of Every
  American
• More than 1,300 NASA and other U.S. space
  technologies have contributed to U.S. industry,
  improving our quality of life and helping save
  lives.
• Image processing used in CAT Scanners and MRI
  technology in hospitals worldwide came from
  technology developed to computer-enhanced
  pictures of the Moon for the Apollo programs.
• Kidney dialysis machines were developed as a
  result of a NASA-developed chemical process, and
  insulin pumps were based on technology used on
  the Mars Viking spacecraft.
• Programmable Heart Pacemakers were first
  developed in the 1970s using NASA satellite
  electrical systems.

Why Explore?

• Space Technology Affects the Lives of Every
  American
• Fetal heart monitors were developed from
  technology originally used to measure airflow
  over aircraft wings.
• Surgical probes used to treat brain tumors in
  children resulted from special lighting
  technology developed for plant growth experiments
  on Space Shuttle missions.
• Infrared hand-held cameras used to observe
  blazing plumes from the Shuttle have helped
  firefighters point out hot spots in brush fires.
• Satellite communications allow news organizations
  to provide live, on-the-spot broadcasting from
  anywhere in the world families and businesses to
  stay in touch using cellphone networks and the
  simple pleasures of satellite TV and radio, and
  the convenience of ATMs across the country and
  around the world.

Why the moon?

• The moon is a rich laboratory
• The history of our solar system is preserved and
  readable in the ancient dust of the lunar
  surface.
• An understanding of the impact hazard in the
  Earth-moon system
• An unraveling of the processes and evolution of
  our sun, the major driver of climate and life on
  Earth.

7
Why the moon?

• The moon is a stable platform to observe the
  universe
• Its far side is the only known place in the solar
  system permanently shielded from Earth's radio
  noise.
• That allows observation of the sky at radio
  wavelengths never before seen.
• Every time we open a new spectral window on the
  universe, we find unexpected and astounding
  phenomena.

8
Why the moon?

• The moon is close, yet very foreign
• Only three days away, but filled with mysteries,
  landscapes and treasures.
• An inspiring and difficult task of living and
  working there,
• Learn how to explore a planetary surface
• Learn how the combined efforts of both humans and
  machines can enable new levels of productive
  exploration.

9
Why the moon?

• The moon is rich in resources
• With its resources and proximity to Earth, the
  moon is a natural logistics and supply base,
• Energy and materials
• An offshore island of useful commodities for use
  there, in space, and ultimately back on Earth

10
Why the moon?

• The moon poles may contain 10 billion tons of
  water
• Water supports life and can be broken down into
  its two components, hydrogen and oxygen.
• These elements make the highest-energy chemical
  rocket propellant known.
• 10 billion tons enough to launch a fully fueled
  space shuttle once a day, every day, for over 39
  years.

11
Why the moon?

• Solar power on the moon
• The moon's slow rotation, unclouded skies and
  abundant local materials make it possible to
  build installations specifically designed to
  harvest solar energy there.
• Collected on the moon and beamed to Earth and
  throughout the space between the two, can provide
  a clean and reliable energy source for
  space-based applications and for users on Earth
  as well.
• Instead of launching arrays from the deep gravity
  well of Earth, we would use the local soil and
  make hundreds of tons of solar panels on the
  moon.

12
Why the moon?

• The moon is the staging ground, supply station
  and classroom for our voyage into the universe
• Living on the moon will expand the sphere of
  human and robotic activity in space beyond
  low-Earth orbit. We must
• Master the skills of extracting local resources
• Build our capability to journey and explore in
  hostile regions
• Create new reservoirs of human culture and
  experience

Engineering Design

• Engineering
• The systematic application
• of mathematical, scientific, and technical
  principles
• that yields a tangible end product
• that meets our needs or desires.

Ingenuity Design Firm

• Transportation
• How will we get to the moon and back to the
  Earth?
• How will supplies be carried?
• As weight goes up, so does the cost and
  propulsion requirements. How does this impact
  shelter design?
• How to we travel on the surface of the moon?
