<p> Exhibit: SPACE 4.15 Terraforming Table Terraforming Script DRAFT v18</p><p>I/A KEY: Phase = Terraforming and the I/A occurs in 2 sequential phases. A 3rd phase shows final results. Cut Scene = Video sequence w/ no user control. Each phase has its own cut scene that loops seamlessly to the next. Tool = Main user interface. There are 10 tools divided between phase 1 and 2. Explain: 1) what is the tool; 2) what does it do</p><p>SCRIPT KEY: Italic bold text = Cut Scene narration. </p><p> text = TOOLS text</p><p>PHASE Cut Scene Tool</p><p>PHASE 1 Terraforming Mars Touch to start</p><p>Change the atmospheric and soil chemistry of the planet to make it more hospitable for human habitation.</p><p>Should humans ever devote the time and resources to making Mars hospitable to life from Earth?</p><p>To see what that change involves, simulate the terraforming of Mars and decide for yourself.</p><p>Could we transform an entire planet to make it habitable?</p><p>[Narrated:] Terraforming Mars — phase one. </p><p>Launch the tools to thicken the atmosphere with greenhouse gases and warm the planet.</p><p>Continue until the average surface temperature on Mars rises above the freezing point of water. </p><p>Touch here to join in PHASE Cut Scene Tool</p><p>Average Surface Temperature Terraforming Tools Touch one to being FACTORIES Build factories that process Martian minerals to release complex carbon greenhouse gases into the atmosphere.</p><p>Chemicals in the atmosphere and minerals in the soil can combine into complex carbon gases all across on Mars. </p><p>BOMBS Release powerful explosions to quickly vaporize frozen carbon dioxide and water at the Poles. </p><p>Set bombs in orbit around Mars and drop them over the Poles.</p><p>Release ASTEROIDS Crash an asteroid into Mars. The impact energy will quickly warm the entire planet. </p><p>Some asteroid impacts will release ammonia or methane, greenhouse gases many times more powerful than carbon dioxide.</p><p>Crash MIRRORS Deploy vast orbiting mirrors to focus sunlight directly on the Martian surface. </p><p>Target the Poles to vaporize greenhouse gases frozen in the Polar caps. </p><p>Deploy DUSTER Scatter dark dust over large areas. Dark surfaces absorb more solar energy – speeding up any warming methods already in place.</p><p>Scatter</p><p>PHASE 2</p><p>Phase one complete. </p><p>The average temperature on Mars is </p><p>Created by: Mark Iscoe, Sarah Galloway and Stuart Fox Page: 2 PHASE Cut Scene Tool</p><p> above freezing. </p><p>The planet has an insulating atmosphere and liquid water—essential life supports.</p><p>For phase two, raise oxygen levels and prepare soil for plant life.</p><p>Deploy simple organisms, then more complex plants, imported from Earth. </p><p>Oxygen Level 0 mbar</p><p>Touch here to join in</p><p>TERRAFORMING TOOLS Touch one to begin</p><p>Waiting for other users MICROBES Colonize newly melted water with bacteria and algae. </p><p>These microbes break down rocks, transform carbon dioxide into oxygen.</p><p>CO2, O2 </p><p>Requires: carbon dioxide, sunlight, liquid water, rocky surfaces</p><p>COLONIZE LICHENS Lichen Cover rocky surfaces with lichen. </p><p>Lichen produce oxygen and create soil by chemically eat away at rocks.</p><p>Spreading lichen also darkens the ground, allowing it to absorb more solar energy.</p><p>COVER</p><p>Requires: carbon dioxide, sunlight, moist air, rocky surfaces MOSSES Place mosses in damp, shady locations with ground soil. </p><p>Mosses add nutrients to the soil and pump increasing amounts of oxygen into the air.</p><p>Sulfur, nitrogen, phosphorus, magnesium, </p><p>Created by: Mark Iscoe, Sarah Galloway and Stuart Fox Page: 3 PHASE Cut Scene Tool</p><p> potassium, calcium</p><p>Requires: carbon dioxide, sunlight, moist air, oxygen, soil</p><p>PLACE FLOWERS Seed tough, cold resistant, flowering plants, like grasses and shrubs, in rocky, dry areas.</p><p>The plants create nutrient-rich soil so trees can take root.</p><p>Requires: carbon dioxide, sunlight, moist air, oxygen, richer soil, rainfall</p><p>SEED Trees Plant trees in lower elevations to pump out large amounts of oxygen year-round. </p><p>Eventually, these tall trees will spread towards mountaintops and colder regions.</p><p>PLANT</p><p>Requires: carbon dioxide, sunlight, moist air, oxygen, rich soil, rainfall</p><p>PHASE 3 Congratulations! You have terraformed Mars from a cold, dead planet into a warm, vital planet with green forests, blue oceans and a sustainable ecosystem. </p><p>The liquid water feeds plants and settlers, and the spreading forests will soon produce enough oxygen to allow human colonists to breathe without help. </p><p>Hiking is easier in low gravity, but at least for now, you still have to bring along an oxygen tank. </p><p>Created by: Mark Iscoe, Sarah Galloway and Stuart Fox Page: 4</p>
