Potter","doi":"10.2514/6.2018-5368","DOIUrl":"https://doi.org/10.2514/6.2018-5368","url":null,"abstract":"This paper and presentation is intended to address the challenges of power beaming from the perspective of a focused incremental Technology Development, Demonstration, and Deployment (TD) mission for Space-to-Space Power Beaming (SSPB) to be implemented as a commercial International Space Station (ISS) TD mission. The SSPB mission builds on foundational research in the field and mission development work accomplished to date by XISP-Inc. The SSPB mission is intended to help mitigate cost, schedule, and technical risk associated with the short-, mid-, and long-term application of space power and ancillary services (e.g., data, communications, navigation, time, etc.) beaming technology. This mission involves significant technology development, demonstration, and deployment elements, orchestrated and implemented in a manner that delivers significant value to a number of customers co‐orbiting with the ISS, and will serve as a testbed environment for more expansive SSPB TD efforts. The latest estimated deliverable power-density and power-received values based on the collection efficiency calculations (which have been correlated to ground tests by other researchers) provide a compelling comparison between estimated delivered power density and the Solar Constant for the orbital distance of immediate interest. The calculated values clearly show that the low end of the Ka band (i.e., 26.5 GHz shown), with a delivered power density an order of magnitude less than the Solar Constant, is very benign. The high end of the Ka band (i.e., 36 GHz shown) can actually meet some customer requirements, though at best at a small multiple of the Solar Constant. However, the W band (i.e., 95 GHz) can provide a power density an order of magnitude or higher than the Solar Constant. The challenge in all instances is engineering systems with an end-to-end efficiency which is satisfactory and sufficient for the application. The ability to provide power when and where needed is essential to virtually all aspects of human endeavour, and is enabling for any form of space development/settlement. Space solar power technology holds the promise of being one of the few large-scale energy generation options that can scale to meet the growing electrical energy demand in space. This mission is a unique opportunity to foster the development of SSPB by leveraging ground based piecewise testing and ISS resources to create an integrated SSPB testbed environment on and near the ISS that supports the development of frequency-agnostic-radiant-energy beaming technology.","PeriodicalId":366106,"journal":{"name":"2018 AIAA SPACE and Astronautics Forum and Exposition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127136752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fikes, Mallory M. Johnston, R. Mueller, B. Khoshnevis","doi":"10.2514/6.2018-5127","DOIUrl":"https://doi.org/10.2514/6.2018-5127","url":null,"abstract":"Disruptive technologies are unique in that they spawn other new technologies and applications as they grow. These activities are usually preceded by the question, “ What If ?” For example, “ What if we could use an emerging technology and in-situ materials to promote exploration on the Moon or Mars, and then use that same technology to keep our troops out of harm’s way and/or help the worlds’ homeless?” This question allows us to flip the mindset of “how can people create more valuable innovation?” to “how can innovation create more valuable people?.” This approach allows us to view augmented human labor as an inclusive opportunity, not a threat. The discipline of Additive Construction is growing rapidly due to the flexibility, speed, safety and logistics benefits offered as compared to standard construction techniques. Additive construction is a disruptive technology in that it employs the principles of additive manufacturing on a human habitat structure scale. Developed initially for In-Space Manufacturing, Technical Advanced Materials & Manufacturing, Exploration Technologies & Systems and now into military and (Moon and surface infrastructure as well. Additive Construction with Mobile Emplacement (ACME) is a NASA technology development project that seeks to demonstrate the feasibility of constructing shelters for human crews, and other surface infrastructure, on the Moon or Mars for a future human presence. The ACME project will allow, for the first time, the 3-dimensional printing of surface structures on planetary bodies using local materials for construction, thereby tremendously reducing launch and transportation mass and logistics. Some examples of infrastructure that could be constructed using robotic additive construction methods are landing pads, rocket engine blast protection berms, roads, dust free zones, equipment shelters, habitats and radiation shelters. Terrestrial applications include the development of surface structures using Earth-based materials for emergency response, disaster relief, general construction, and housing at all economic levels. This paper will describe the progress made by the NASA ACME project with a focus on prototypes and full scale additive construction demonstrations using both Portland cement concrete and other indigenous material mixtures. Rationale for the use of additive construction for both terrestrial and planetary applications will be explored and a thorough state-of-the-art of additive construction techniques will be presented. An evolutionary history of NASA’s additive construction development efforts, dating back to 2004, will be included. The paper will then step through a series of trade studies performed to inform key processing and design decisions in the development of the full-scale ACES-3 system developed by NASA and the Jacobs Space Exploration Group for the U.S. Army Corps of Engineers (USACE) Construction Engineers Research Laboratory (CERL) in Champaign, IL.

{"title":"Impact of Lower Launch Cost on Space Life Support","authors":"Harry W. Jones","doi":"10.2514/6.2018-5286","DOIUrl":"https://doi.org/10.2514/6.2018-5286","url":null,"abstract":"The development of commercial launch systems has substantially reduced the cost of space launch. NASA’s Space Shuttle had a cost of about $1.5 billion to launch 27,500 kg to Low Earth Orbit (LEO), $54,500/kg. SpaceX’s Falcon 9 now advertises a cost of $62 million to launch 22,800 kg to LEO, $2,720/kg. Space launch costs were very high for decades, typically about $20,000/kg, and it was understood that this high launch cost made it necessary for long human missions to recycle water and oxygen to reduce logistics mass. Short missions such as Apollo or Shuttle used stored and resupplied life support materials, but for a much longer mission such as the International Space Station (ISS), recycling saves logistics mass and reduces launch cost. The Life Cycle Cost (LCC) will be computed for resupply logistics and for a recycling system similar to that on the ISS. The LCC includes the costs of development, launch, and operations. The new low launch cost makes open loop life support much cheaper than before. Direct logistics resupply would be less costly than recycling for future human missions, such as a long term moon base, a Mars mission, or a future space station in LEO.","PeriodicalId":366106,"journal":{"name":"2018 AIAA SPACE and Astronautics Forum and Exposition","volume":"320 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115748946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
