Location Longitude, Latitude: 88° 36′ 0″ N, 33° 0′ 0″ E The location we have selected is Peary Crater, located near the Northern pole of the moon. It is approximately 73 kilometers in diameter.  Four mountainous regions of the crater appear to be illuminated throughout all of the Lunar Day, providing continuous solar power and stable temperatures averaging 50 degrees Celsius. The perpendicular axis of the moon means that locations near the Northern and Southern poles of the moon remain almost permanently sunlit. The location also provides some permanently shadowed areas that may have frozen water. These locations have been identified along the walls of the crater, hidden from direct sunlight. Daily temperature changes would be only about 36° Fahrenheit [20° Celsius] said Ben Bussey, the leader of a team at the John Hopkins University Applied Physics Laboratory that has been researching the Peary Crater. It is around 212 degrees Fahrenheit (100 Celsius) to minus 292 Fahrenheit (-180 Celsius) near the equator. Preliminary Mission : Preliminary Mission Goals: Survey Peary Crater for suitable LBH-30 location near latitude/longitude 88° 36′ 0″ N, 33° 0′ 0″ E, and search for locations of natural resourses which can be used to facilitate the LBH-30. Deliver materials, supplies and machinery. Prepare the area for the construction of of the LBH-30. Prepare sand bags for placement on the inflated LBH-30 structure. Ares V Rocket: The Ares V rocket is a two-stage vertically stacked launch vehicle which will be used to transfer materials six months prior to the arrival of the astronauts.The Ares V rocket can carry a maximum payload of 71,100 kg into earth orbit, and will be used in tandem with the Ares I rocket, which will be used to send the astronaut crew to the moon. The machinery and resourses necessary for the construction of the base will be sent along with the LBH-30 and its components in the Ares V rocket. Supplies List: The most important components of the mission are listed below. *Note: Mass is measured assuming the thickness of the kevlar base is 1 inch thick. Kevlar has a density of 1.44 grams/cc . Steel beams are 4 inches wide, 4 inches in depth, and 7.85 meters in length. Base Structure (Inflatable base) : Base Structure (Inflatable base) Greenhouse Base covered with lunar-regolith bags Oxygen Tank Water Tank Waste Door Protective Shell : Protective Shell Sandbags: The base will have be covered in 942 sandbags, with individual dimensions of (0.25 meters x 0.5 meters x 1 meter). The thickness of the Kevlar used for the sandbags will be .25”, or 0.00635 meters. These dimensions are necessary to provide protection from lunar conditions. The cumulative mass of each sandbag will amount to 14,650 kg. The cumulative volume of the sandbags will occupy a volume of 10.17 cubic meters. 107.4 cubic meters of lunar regolith will fill the sandbags. Kevlar Tarp: Over the 1 meter layer of sandbags, a 0.25 inch 175 square meter Kevlar tarp will be placed under tension to ensure the sandbags stay in place. The Kevlar tarp will occupy a volume of 1.11 cubic meters, with a mass of 1600 kg. Right: Cross-sectional image of a portion of the LBH-30. Yellow represents the Kevlar tarp, white represents the regolith sandbags, and black represents the pressurized space in which the astronauts reside. Note: Not to scale Slide 6: = air tight doors Future expansion Toilet Docking station for rover Floor Plan Life Support : Life Support About 1416 kg of water is needed for the mission. We will need a 207 lb oxygen tank. We need 106.2 kg of food. The greenhouse will produce 352 kg of food approximately. Oxygen : Oxygen Slide 9: Power Water/Waste : Water/Waste Water/Waste(cont’d) : Water/Waste(cont’d) Water/Waste(cont’d) : Water/Waste(cont’d) 50 Gallons of water will be brought initially. ~375 Gallons will be needed through the entire duration of the trip, but the initial amount will be continually recycled. If necessary, additional water can be collected. The system employed on the lunar base is similar to the one on the International Space Station. Appliances and bathrooms would require little water.
