Grade 9 Applied Science - Space Surviving on the Moon Objective To understand the essentials for survival on the Moon Methods 1. Your spaceship has just crash-landed on the Moon. You are 320 km away from Moon Base. It is midday (NOTE: A Moon Lunar Day lasts 14 Earth days). Your crew’s survival depends on reaching the base. 2. Choose the five most critical items from the following 15 items salvaged from your wrecked ship. Your task is to rank the items in terms of their importance for survival on your trek to the safety of the base. 3. Place number one by the most important item, number two by the second most important item, and so on through number fifteen, the least important item. If you get four of the top five items correct, you will survive Items ITEM Box of matches 15 m of nylon rope Two .45 caliber pistols Self-inflating life raft 38 L of water Solar-powered FM receiver-transmitter Stellar (star) map 45 kg tanks of oxygen Solar-powered portable heating unit Food concentrate Parachute One case of dehydrated milk Magnetic Compass Signal Flares First Aid Kit with spacesuit injecting needles YOUR NUMERIC RANK Group One: Essentials 1. 2. 3. 4. 5. Air is essential to sustaining life so it should be the #1 priority. Water is also necessary during your multi-day lunar hike so it is #2. A star map will help you find your way to the base; after basic survival it’s tops. Food will keep your strength up. The solar-powered radio may enable you to call for rescue, shortening your ordeal. Group Two: Potentially useful 6. Rope could help you traverse difficult terrain. 7. The first aid kit could be a lifesaver. 8. You could make a sunshade with the parachute canopy, but there is no atmosphere on the Moon. 9. Signal flares might help you when you are very close to the base. 10. Dehydrated milk could add to your food but is not absolutely essential for the hike. Group Three: Arguably Deadweight on the Moon 11. Self-inflating life raft. Some have argued to use the carbon dioxide bottle for propulsion. This might be true in weightlessness, but it isn’t large enough to use on the Moon 12. Solar-powered portable heating unit. The problem during the day will be too much heat 13. Pistols. It has been suggested that you could use the pistols for propulsion but this will not work in the Moon’s gravity field. 14. Magnetic Compass. A compass will not work on the Moon because, unlike the Earth, it has no appreciable magnetic field. 15. Matches. These won’t work on the airless Moon.
