China's lunar probe soft-lands on moon
Posted on 12/14/2013 9:53:16 AM PST by Hojczyk
BEIJING, Dec. 14 (Xinhua) -- China's lunar probe Chang'e-3, with the country's first moon rover onboard, successfully landed on the moon on Saturday night, marking the first time that China has sent a spacecraft to soft land on the surface of an extraterrestrial body.
The lunar probe began to carry out soft-landing on the moon at 9 p.m. Saturday and touched down in Sinus Iridum, or the Bay of Rainbows, 11 minutes later, according to Beijing Aerospace Control Center.
During the process, the probe decelerated from 15 km above the moon, stayed hovering at 100 meters from the lunar surface to use sensors to assess the landing area to avoid obstacles and locate the final landing spot, and descended slowly onto the surface.
The success made China the third country, after the United States and the Soviet Union, to soft-land on the moon.
Compared to those other two countries, which have successfully conducted 13 soft-landings on the moon, China's soft-landing mission designed the suspension and obstacle-avoiding phases to survey the landing area much more precisely through fitted detectors, scientists said.
The probe's soft-landing is the most difficult task during the mission, said Wu Weiren, the lunar program's chief designer.
Chang'e-3 relied on auto-control for descent, range and velocity measurements, finding the proper landing point, and free-falling.
The probe is equipped with shock absorbers in its four "legs" to cushion the impact of the landing, making Chang'e-3 the first Chinese spacecraft with "legs."
Chang'e-3 adopted a variable thrust engine completely designed and made by Chinese scientists. It can realize continuous variation of thrust power ranging from 1,500 to 7,500 newtons, according to Wu Weiren.
The soft-landing was carried out 12 days after the probe blasted off on an enhanced Long March-3B carrier rocket.

I think their aim was to open the first Chinese restaurant there in anticipation of the expected tourist rush.
Big deal. We have affordable health care.

Chang'e-3 adopted a variable thrust engine completely designed and made by Chinese scientists.
And I'd guess that everything else was designed by the old Soviets.

This should be a BIG heads up as to Red China aiming to be the biggest and baddest superpower. Their military [People’s Army runs the rocket program, not some NASA] has mastered the capability to go to the Moon with a lander/rover and drive it around. This level of technology means every inch of our globe can be targeted and threatened from China or a near orbit platform.
Meanwhile our government is missing in action as to our space program, military rocket program, updates for our nuclear bombs and resolve to continue to be a world power.

Did they properly thank Loral space?
Is China a signatory to this stupid UN resolution?
The exploration and use of outer space, including the moon and other celestial bodies, shall be carried out for the benefit and in the interests of all countries, irrespective of their degree of economic or scientific development, and shall be the province of all mankind.
Outer space, including the moon and other celestial bodies, shall be free for exploration and use by all States without discrimination of any kind, on a basis of equality and in accordance with international law, and there shall be free access to all areas of celestial bodies. There shall be freedom of scientific investigation in outer space, including the moon and other celestial bodies, and States shall facilitate and encourage international co-operation in such investigation.

Mare Imbrium is such a well defined Mare . I admire it when I look at it . Didn’t know there were sub parts of it
It's a sort of an add-on, really a separately formed feature, as it appears. ( and oops, that's Sinus IRIDUM . ) Here's an excellent view with the sun angle just right to see Cassini's "Lady in the Moon". She's at the lower right peering towards the upper left.

Kind of looks Chinese, doesn't it?
Here's "the old surveyor" ... which looks like a piece of junk!
The LM had some class, though.

The funny thing is that it didn't land in Sinus Iridum after all. I noticed this in the 10 minute video clip from CCTV
showing the deployment of the rover. Around 10:05 there's a brief shot of the control room with a big screen, and you can make out the apparent mark of the landing spot on the right side. The position matches the coordinates and interactive map given in the Yutu (rover)
Wikipedia article ( bottom of box on right side. )
Here are three screen shots of the deployment, the control room screen, and the interactive map from Wikipedia. ( Of course, the red spot marks the landing site. )
On the control room screen the big rectangle apparently marked the zone of possible landing sites, and it heavily overlaps Sinus Iridum. I suppose that the actual spot depended on the timing of the landing as it was in polar orbit.
