Editing Ansari X Prize (section)

==Spin-offs==
The success of the X Prize competition has spurred spin-offs that are set up in the same way. There have been two major spin-offs at this point, the first of which is the [[Methuselah Mouse Prize|M Prize]] (short for Methuselah Mouse Prize), which is a prize set up by [[University of Cambridge]] [[biogerontology|biogerontologist]] [[Aubrey de Grey]] which will go to the scientific team that successfully extends the life or reverses the aging of mice, which would then eventually be available to humans. The second is the NASA [[Centennial Challenges]], which consist of (among others) the [[Tether Challenge]] in which teams compete to develop superstrong tethers as a component to [[space elevator]]s, and the [[Beam Power Challenge]] which encourages ideas for transmitting power wirelessly. An independent spin-off called the [[N-Prize]] was started by [[Cambridge]] [[Microbiologist]] Paul H. Dear in 2007, designed to foster research into low-cost orbital launchers.

The X Prize foundation itself is developing additional prizes: the [[Archon X Prize]], to advance research in the field of [[genomics]]; the [[Automotive X Prize]], an engineering competition to create a fuel efficient clean car;<ref>{{cite web|url=https://www.socaltech.com/fullstory/0003465.html |title=Interview with Mark Goodstein, Executive Director of the Automotive X Prize on new energy X Prize|access-date=January 28, 2023}}</ref><ref>{{cite web|url=https://www.xprize.org/prizes/auto |title=Progressive Insurance Automotive X Prize|access-date=February 13, 2023}}</ref> the [[Wirefly X Prize Cup]], an annually held air & space exposition featuring space-related competitions and rocketry, and the [[Google Lunar X Prize]], a competition for privately funded lunar exploration. Of several awards on offer, the largest—$20 million—will be awarded to the first privately funded team to produce a robot that lands on the [[Moon]] and travels 500&nbsp;m (1,640&nbsp;ft) across its surface.<ref>{{Cite book|title=Guinness World Records 2014|last=Glenday|first=Craig|year=2013|isbn=978-1-908843-15-9|pages=[https://archive.org/details/guinnessworldrec0000unse_r3e7/page/184 184]|url=https://archive.org/details/guinnessworldrec0000unse_r3e7/page/184}}</ref><ref>{{Cite web|url=https://www.xprize.org/prizes/google-lunar|title =THE NEW SPACE RACE}}</ref>

There is also a possible "[[H-Prize]]", focused on [[hydrogen vehicle]] research, although this goal has been addressed by [[H.R. 5143]], an X-Prize-inspired bill passed by the [[United States House of Representatives]], which was later folded into the [[Energy Independence and Security Act of 2007]].<ref>{{cite web |title=H.R.5143 - H-Prize Act of 2006|date=11 May 2006|access-date=2015-10-11|url=https://www.congress.gov/bill/109th-congress/house-bill/5143|publisher=Congress.gov}}</ref>
