=== Moon regolith Oxygen (MoonROx) challenge ===
This head-to-head competition was for a system capable of extracting 2.5 kilograms of oxygen from 100 kilograms of artificial lunar [[regolith]] in 4 hours or less using at most 10&nbsp;kW of power.<ref>{{cite web |url=http://www.fsri.org/space_research_Moon_ROx.htm |title= FSRI: Space Research|website=www.fsri.org |archive-url=https://web.archive.org/web/20050924103136/http://www.fsri.org/space_research_Moon_ROx.htm |archive-date=September 24, 2005}}</ref>  This US$1 million prize expired in June 2009 without a winner.{{Citation needed|date=September 2010}}

The initial MoonROx challenge was announced in 2005 with the intent to award a US$250,000 prize to the first team to develop the capability to extract 5 kilograms of breathable oxygen from simulated lunar soil in an eight-hour period. The prize expired in June 2008.<ref name=nasa200505>

For the initial announcement of the challenge, the competition was to be administered by the [[Florida Space Research Institute]] (FSRI) in collaboration with NASA.<ref name=nasa200505/>
The next year the [[California Space Education and Workforce Institute]] (CSEWI) was selected to administer the challenge when FSRI was dissolved and [[Space Florida]] was created to take its place.<ref name=nasa20080205>{{Cite web|url=http://ipp.nasa.gov/documents/cc_update_10-2006.pdf|title=Centennial Challenges Update &mdash; October 2006|access-date=2010-09-18|archive-date=2011-07-21|archive-url=https://web.archive.org/web/20110721051230/http://ipp.nasa.gov/documents/cc_update_10-2006.pdf|url-status=dead}}</ref>

Since extracting oxygen from silicates is difficult, and the oxygen electrochemically bound into the silicates at high temperature, it is likely that a solar-furnace may be part of the solution.{{Citation needed|date=September 2010}}
