Quote from: Lar on 12/10/2013 10:04 pmdropping the last 4 feet seems risky... how does this compare to other lunar landings? I didn't think the Apollo LEM cut engines that high up at all...It was a bit of a drop on Apollo to be sure... check out what happened to 15's engine bell (top right) from the drop: http://commons.wikimedia.org/wiki/File:Apollo_15_Engine_Bell.jpg

For H=4 meters we have:v= 1.8 * 2 = 3.6 m/s = 13 km/hCan anybody confirm my calculations?

...the lander and the rover will capture some photographs of each other using the equipped cameras. and both are painted with the national flag, therefore, a color photo of the chinese national flag on the moon can be captured.
So they must be currently imaging the landing area

yep. that would be unprecedented. plus, I don't see the interest since CE-2 mapped the area at 1.5 m resolution

Told ya there'd be a flag.Is it landing on December 15th?
