China?sfirst moon probe Chang?e 1 intentionally crashed into the lunar surface onSunday after more than year of science observations, according tostate media reports.
The Chang?e1 orbiter fired its engines to leave lunar orbit Sunday afternoon andultimately slammed into the moon?s southern region at 4:13 p.m. Beijing Time(0813 GMT), China?s state-run Xinhua News Agency reported.
Launchedin October 2007, the 5,180-pound (2,350-kg) satellite Chang?e 1 spacecraftorbited the moon for 16 months. During its flight, the spacecraft used eightonboard instruments to map the lunar surface, study its composition anddepth, as well as analyze the space environment around the moon.
Chinesespace officials said they planned to launcha follow-up mission — Chang?e 2 — by 2011. Chang?e 1?s intentional crashwas slated to be a dry run for a potential moon landing, they said Sunday.
Chang?e 1 wasa named after a Chinese goddess who, in a popular fairy tale, lives on the moon.The mission cost a reported 1.4 billion yuan (about $180 million), according topast Chinese media reports.
Officialswith the China National Space Agency have said Chang?e 1 was the first wave ina three-phase plan to explorethe moon with orbiters, landers and rovers.
"Thesecond phase of the space program aims at soft landing, and the preparation iscurrently in progress", said Wu Weiren, chief designer of the country'slunar probe program, according to Xinhua.
That softlanding is slated to be performed by yet another probe, Chang?e 3, by no laterthan 2013, Chang?e 1 chief designer Ye Peijian told Xinhua. A fourthChang?e probe would also fly during the second phase of lunar exploration, headded.
China?sthird phase of lunar exploration includes landing ?recoverable moon rovers? onthe lunar surface between 2017 and 2020, Ye told Xinhua. Those probes, however,may not carry the Chang?e moniker.
"Thename hasn't been decided yet," Ye told Xinhua.
