The cooling of SBDCs can be realized via using water aboard asteroids. The feasibility of this approach requires further consideration and has not received sufficient research attention. The study being presented investigates the existence of water-bearing asteroids whose water resources can potentially be used for cooling the server payloads aboard the SBDC. This is undertaken by executing multi-criteria search queries on the Asterank asteroid database. Data analysis shows that water can be accessed from asteroids at less than 0.26 AU by privately owned space vehicles designed for Earth-to-Mars missions. In addition, the results of data analysis show that there is a regularity and symmetric pattern among different asteroids. This arises as asteroids with different identities have the same near-Earth distance and upcoming approaches.<\/jats:p>","DOI":"10.3390\/sym15071326","type":"journal-article","created":{"date-parts":[[2023,6,29]],"date-time":"2023-06-29T00:41:45Z","timestamp":1687999305000},"page":"1326","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Space-Based Data Centers and Cooling: Feasibility Analysis via Multi-Criteria and Query Search for Water-Bearing Asteroids Showing Novel Underlying Regular and Symmetric Patterns"],"prefix":"10.3390","volume":"15","author":[{"given":"Ayodele","family":"Periola","sequence":"first","affiliation":[{"name":"Electrical, Electronic and Computer Engineering, Cape Peninsula University of Technology, Bellville 7530, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4319-7881","authenticated-orcid":false,"given":"Akintunde","family":"Alonge","sequence":"additional","affiliation":[{"name":"Electrical and Electronic Engineering Technology, University of Johannesburg, Johannesburg 2092, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6589-4904","authenticated-orcid":false,"given":"Kingsley","family":"Ogudo","sequence":"additional","affiliation":[{"name":"Electrical and Electronic Engineering Technology, University of Johannesburg, Johannesburg 2092, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1038\/s41545-021-00101-w","article-title":"Data center water consumption","volume":"4","author":"Mytton","year":"2021","journal-title":"Npj Clean Water"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Periola, A., Alonge, A., and Ogudo, K.
