The Google Lunar XPRIZE (GLXP), sometimes referred to as Moon 2.0,〔 〕 is an inducement prize space competition organized by the X Prize Foundation, and sponsored by Google. The challenge calls for privately-funded spaceflight teams to compete to successfully launch a robotic spacecraft that can land and travel across the surface of the Moon while sending back to Earth specified images and other data. In 2015, Google announced that the deadline for winning the prize will be extended to December 2017 if at least one team can show a launch contract by December 31, 2015. Two teams secured such a launch contract and the deadline was extended accordingly. 〔 (Deadline For $30 Million Google Lunar XPRIZE Extended To End Of 2017 ), May 22, 2015, (downloaded 15 June 2015)〕 , 16 GLXP teams remained in the competition, and five of those were thought to be making good progress. While none of the GLXP teams had announced firm launch dates to attempt the prize by mid-2014,〔 team Moon Express signed a contract with Rocket Lab on Sept. 30 to launch three Moon Express robotic spacecraft to land on the Moon, with two launches manifested in 2017, utilizing an Electron launch vehicle, and announced the contract on 1 October 2015,〔()〕 and the Israeli team SpaceIL booked a launch on the Spaceflight “2017 Sun Synch Express” mission, utilizing a SpaceX Falcon 9 and announced the contract on 7 October 2015.〔(BBC )〕 As of October 2015, SpaceIL and Moon Express are the only GLXP teams to have current announced launch contracts. ==Competition summary== The Google Lunar XPRIZE was announced at the Wired Nextfest on 13 September 2007.〔 〕 The prize offers a total of US$30 million in prizes to the first privately funded teams to land a robot on the Moon that successfully travels more than 500 meters (1,640 ft) and transmits back high definition images and video. The first team to do so will claim the US$20 million Grand Prize; while the second team to accomplish the same tasks will earn a US$5 million Second Place Prize. Teams can also earn additional money by completing additional tasks beyond the baseline requirements required to win the Grand or Second Place Prize, such as traveling ten times the baseline requirements (greater than 5,000 meters (3 mi)), capturing images of the remains of Apollo program hardware or other man-made objects on the Moon, verifying from the lunar surface the recent detection of water ice on the Moon, or surviving a lunar night. Additionally, a US$1 million Diversity Award may be given to teams that make significant strides in promoting ethnic diversity in STEM fields. Finally, Space Florida, one of the "Preferred Partners" for the competition has offered an additional US$2 million bonus to teams who launch their mission from the state of Florida. To provide an added incentive for teams to complete their missions quickly, it was announced that the prize would decrease from US$20 million to US$15 million whenever a government-led mission lands on and explores the lunar surface.〔(【引用サイトリンク】url=http://www.googlelunarxprize.org/prize-details )〕 The Chinese Chang'e 3 probe landed on the Moon in December 2013, however, in November 2013, as the launch of the probe approached, it was agreed between the organizers and the teams to drop this rule.〔(【引用サイトリンク】title=A New Player in the Return to the Moon )〕 As of October 2015, The Astrobotic team announced it would be willing to share a single "ride" to the Moon with up to four competitors. The shared transporter, including a shared Lunar landing, would result in a common start time for a race to achieve the 500 meter lunar-surface distance-traveled objective. In February 2015, Astrobotic announced a partnership with Hakuto for an arrangement to share a prospective SpaceX launch and the Astrobotic ''Griffin'' lander for the XPRIZE competition,〔 〕 and as of October 2015 the company states that it plans to launch on a SpaceX Falcon 9 rocket, but has not yet signed a launch contract.〔()〕 The Google Lunar XPRIZE expires when all constituent purses have been claimed, or at the end of the year 2017, whichever comes first. At the time the prize was announced, the last operational vehicle on the Moon had landed in 1976. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Google Lunar X Prize」の詳細全文を読む スポンサード リンク
