South Korea launched its first lunar orbiter on Friday as it doubles down on its space programmes, aiming to land a probe on the moon by 2030.
The Korea Pathfinder Lunar Orbiter, nicknamed Danuri, meaning "enjoy the Moon", was launched on SpaceX's Falcon 9 rocket from Florida's Cape Canaveral US Space Force Station at 8:08 am on Friday (2308 GMT on Thursday), South Korea's science ministry said.
The 678 kg (1,495 lb) Danuri separated from the projectile about 40 minutes after launch and began communicating with a ground station around 9:40 am, reports Reuters.
"Analysis of the received information confirmed ... Danuri was operating normally," Vice Science Minister Oh Tae-seog told a briefing, announcing that the orbiter had established a trajectory towards the moon.
It will enter the moon's orbit in December before starting a yearlong observation mission, including searching for a landing site and testing space internet technology, the ministry said.
If it succeeds, South Korea will become the world's seventh lunar explorer and the fourth in Asia, behind China, Japan and India.
The launch was initially scheduled for Wednesday but was delayed because of a maintenance issue with the SpaceX rocket.
South Korea has been accelerating its space programme, with the goal of sending a probe to the moon by 2030. It has also joined the Artemis project aimed at returning to the moon by 2024.
In July, South Korea held a second test launch of its domestically produced Nuri rocket and reported its first successful launch of a solid-fuel space-launch rocket in March as part of efforts to launch spy satellites.
Space launches have long been a sensitive issue on the Korean peninsula, where North Korea faces international sanctions over its nuclear-armed ballistic missile programme.
In March, North Korea's leader Kim Jong Un called for expanding its space rocket launch site to advance its space ambitions, after South Korea and the United States accused it of testing a new intercontinental ballistic missile under the guise of launching a space vehicle.
South Korea says its space programme is for peaceful and scientific purposes and any military use of the technology, such as in spy satellites, is for its defence.
