A 23rd Century Colony on Mars (03:18)


We see several images of the technology involved in creating a Martian metropolis. Michio Kaku believes we should be a two planet species. Mars has the most possibilities for life; it has a similar composition to the Earth and permafrost for energy.

Mars Colony (02:21)

Domes are ideal structures for extreme environments. The central dome surrounded by smaller domes is built like a fortress. Temperature and air pressure must be strictly regulated within the dome.

Symbiotic Relationships on Mars (03:07)

Life on Mars is stressful, claustrophobic, and foreign. Mars is approximately 1.5 astronomical units from the sun. Earthlings create artificial ecosystems for comfort and environment sustainability. An aquarium is a good example of a recycled environment.

Biosphere 2 (03:24)

In Tucson, Arizona, experts live in a self-contained, environmentally controlled of five ecosystems. The crew experiences a loss of oxygen due to concrete absorption; fresh air is injected into Biosphere 2. The dome environment is the safest place to be on Mars.

Modes of Planetary Mobility (02:43)

Colonist leave the dome to complete research assignments. The Rover, used on the moon, is not large enough. The Chariot has unique features that allow it to move in any direction over most terrains; it has an upright turret for the colonists to stand in.

Designing Planetary Vehicles (02:34)

Future scientist cross the Martian terrain in a Small Pressurized Rover (SPR). The SPR has a top speed of 6 mph, can cover 500 miles, and sustain inhabitants for up to two weeks. It carries space suits experts step into through a rear hatch.

Mobility on Mars (04:20)

Dr. Lee explores a vehicle that is a precursor to the Small Pressurized Rover. It provides experts with practical data for designs. Tracks give the vehicle greater mobility, but can over rotate. Field repairs on Mars are difficult.

Space Suits on Mars (02:15)

Mike Gernhardt explains what it is like wearing a space suit. Experts discuss the design and function of a space suit. Martian micro meteor showers can puncture a space suit; suits have layers of neoprene and Kevlar.

Wearing an MMU (03:28)

Currently, it can take astronauts up to three hours to don an Manned Maneuverable Unit. Experts at MIT create a streamlined space suit called a bio-suit. The life support system for this suit is modular. The helmet shields the sun and has a heads-up display.

A Robotic Side-Kick (03:16)

Ron Diftler demonstrates a robonaut. The robonaut project infuses ingenuity with mechanical muscle. The robot can operate by virtual reality gear or autonomously. Robonaut's size and shape are crucial and it runs on a solar powered lithium ion battery.

Food On Mars (04:21)

It costs approximately $140,000 a pound to transport anything to Mars. Mars regolith is inconsistent. Greenhouses provide the vital factors for growth. Most plants are grown hydroponically and exposed to LEDs. Vibrating wands can help pollinate the plants.

Dining on Mars (02:13)

On Earth, gravity drains water away from plant roots; Mars' gravity cannot sufficiently draw the water. Experts discuss a typical Martian menu; it is a strictly vegetarian diet.

Resources Beyond the Red Planet (02:45)

The largest source of meteorites on Earth come from the asteroid belt. Michio Kaku discusses mining the materials found in the asteroids. Using raw ores can help maintain and construct space craft and facilities. Large asteroids can be worth billions of dollars.

Mining an Asteroid (03:13)

Michio Kaku discusses ways to extract the material out of an asteroid. Radiation in the Asteroid Belt is harsh; miners may have to live inside the asteroid. Robots may replace people as miners. Life on Mars is an extreme adventure.
