Before 2040, NASA and the European Space Agency want to ensure the possibility of a permanent human residence in shelters on the Moon or Mars. The article analyzed the state of the art in this area based on the literature research. It shows innovative and energy efficient solutions for manufacturing the lunar and Martian shelters based on geopolymer composites. Firstly, the possible materials solutions, with particular attention to the geopolymer composites, are discussed. Next, the previous research is presented, including work based on different kinds of simulants of lunar and Martian regolith. Then, a different approach for manufacturing technologies is presented and the advantages of 3D printing technology are clarified. Eventually, the challenges for further projects are discussed, including energy and cost efficiency problems.<\/jats:p>","DOI":"10.3390\/en15249322","type":"journal-article","created":{"date-parts":[[2022,12,9]],"date-time":"2022-12-09T03:59:46Z","timestamp":1670558386000},"page":"9322","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["An Overview for Modern Energy-Efficient Solutions for Lunar and Martian Habitats Made Based on Geopolymers Composites and 3D Printing Technology"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8265-3982","authenticated-orcid":false,"given":"Kinga","family":"Korniejenko","sequence":"first","affiliation":[{"name":"Faculty of Material Engineering and Physics, Cracow University of Technology, Jana Paw\u0142a II 37, 31-864 Cracow, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4044-8451","authenticated-orcid":false,"given":"Kinga","family":"P\u0142awecka","sequence":"additional","affiliation":[{"name":"Faculty of Material Engineering and Physics, Cracow University of Technology, Jana Paw\u0142a II 37, 31-864 Cracow, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5155-1940","authenticated-orcid":false,"given":"Barbara","family":"Kozub","sequence":"additional","affiliation":[{"name":"Faculty of Material Engineering and Physics, Cracow University of Technology, Jana Paw\u0142a II 37, 31-864 Cracow, Poland"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Soko\u0142owska, J.J., Woyciechowski, P., and Kalinowski, M.
