BEIJING, Nov. 2 (Xinhua) -- The first orbital correction for China's lunar
probe Chang'e-1 is expected to carry out on Friday morning, according to the
moon exploration team.
The move, which was planned to be conducted on Thursday, was canceled as
the probe was traveling on the expected trajectory in an "unexpected precisely"
way after it left the earth orbit late Wednesday, said Wang Yejun, chief
engineer of the Beijing Aerospace Control Center (BACC).
"BACC will issue instructions to Chang'e-1 to ignite two small engines on
board Friday and slightly modulate its trajectory, in a bid to guarantee that
the satellite travels on the pre-set orbit," Wang said.
A second orbital correction might be carried out Sunday, he said.
China successfully launched the Chang'e-1, named after a mythical Chinese
goddess who, according to legend, flew to the moon, on Oct. 24. The probe
entered the earth-moon transfer orbit and began to fly to the moon in a real
sense after completing the fourth orbital transfer on Wednesday.
It is expected to reach the moon's orbit at 11:25 a.m. Monday.

BEIJING, Oct. 26 (Xinhua) -- China's lunar
probe Chang'e-1 is expected to arrive at the apogee of more than 70,000
kilometers from the earth on early Saturday morning after having completed its
second orbital transfer on Friday, according to the moon probe team.
Chang'e-1, China's first moon orbiter, is now moving
on a 24-hour orbit and it is forecast to arrive at the apogee at around5:30 a.m.

BEIJING, Oct. 25 (Xinhua) -- China's first
lunar probe Chang'e-1 completed its first orbital transfer Thursday afternoon,
another key move in its 380,000-km journey to the moon.
The orbital transfer began at 5:55 p.m. and succeeded
after 130 seconds. The probe was transferred to an orbit with a perigee of about
600 km, up from the former 200-km perigee, according to the Beijing Aerospace
Control Center (BACC). Full story
