BEIJING, Nov 5: China’s maiden lunar probe successfully entered the moon’s orbit on Monday, officials said, a critical step in its year-long mission to photograph and map the surface of the celestial body.

Chang’e I blasted off on Oct 24, signalling China’s rising space ambitions and Beijing’s participation in a renewed race to explore the moon with rivals Japan and India.

“We have basically succeeded in entering lunar orbit,” Wang Yejun, head mission engineer, said on China Central Television on Monday.

In August Japan launched its first lunar probe, while India has a planned mission for next year.

In Monday’s critical manoeuvre, Chang’e I fired retro-rockets for 22 minutes, slowing as it approached within 200 kilometres of the moon’s surface and allowing it to be sucked into lunar orbit by the body’s gravitational pull.

The probe will remain in an “elliptical orbit” for the next two days, which will carry it as far as 8,500 kilometres away from the moon before swinging back to within 200 kilometres, Xinhua news agency quoted Ji Gang, an official monitoring the flight, as saying.

As the probe continues to brake, it is expected to enter a “working orbit” on Nov 7, when the craft will circle the moon once every 127 minutes from a stable altitude of about 200 kilometres above the surface.

At that time, Chang’e I will begin its year-long mission of photographing and mapping the lunar surface. Its first pictures are not expected to be transmitted until late this month.

The probe, named after a legendary Chinese goddess who flew to the moon, is the first stage of China’s lunar programme, which includes landing an unmanned rover on the surface by 2012 and a manned mission by around 2020.
