Many in the West, stunned and bothered that the Soviet Union had another space
victory by being the first to image the lunar farside, declared that the photos were
all faked by the USSR. Of course when later missions returned even better images
of the lunar farside and proved that Luna 3 did indeed do what they said it had did,
the controversy vanished.

Now it is China's turn, apparently.

It will be interesting to see if they do put humans on the Moon before anyone
else does, or at least put them in orbit or a cislunar circuit. Certainly by 2020
China will at least have their own space station, if they don't buy the ISS first.
I also expect them to have at least a few probes to Mars as well. I wonder if
we will still be saying their photos there are fake then, too.
