Highlights
Chinese Luna probe successfully took off from the Far Side of the Moon.
Chang'e 6 module landed in a volcanic basin close to the moon's South Pole.
Collected samples of rock and soil expected to be different from the near side of the Moon.
Chinese National Space Administration called the mission an unprecedented feat in lunar exploration.
The probe is due to return in about 3 weeks to a landing site in Inner Mongolia.
Mechanical arm used to collect samples placed the symbol for Tonga, which is China, on the far side of the Moon.
Chinese flag planted on the far side of the moon.
Difficulty in controlling and landing on the Far Side of the Moon due to no line of sight from Earth.
A satellite was launched in April to relay messages for the mission.
Chang'e 6 space probe collected rock and soil samples for two days.
Previous samples from the near side of the Moon are volcanic, unlike the Far Side.
Rocks on the Far Side of the Moon could contain traces of ice, indicating a water source.
Scientists are excited about the potential to build a space station on the Moon.
China believes it is ahead in lunar exploration.
Astrophysicist Professor Quentin Parker discusses the challenge and significance of the mission.
Chang'e 6 mission is similar to Chang'e 5 in terms of lunar sample return from the far side.
About 2 kilograms of lunar rock and soil sample expected to be brought back.
The Far Side of the Moon has a different geology with craters that might contain water ice and helium.
China's space endeavors have been successful with missions to the Moon, Mars, and a space station.
The lunar samples are intended for international collaboration and scientific study.
Transcripts
next to China State media there says the
Chinese Luna probe has successfully
taken off from The Far Side of the Moon
to start its Journey back to Earth the
Chang 6 module landed on Saturday in a
volcanic Basin close to the moon's South
Pole and has collected samples of rock
and soil they're expected to be very
different from rock formations on the
near Side of the Moon the Chinese
National Space Administration called the
mission an unprecedented feat in Luna
exploration
the probe is due to return in about 3
weeks time to a landing site in inner
Mongolia let's hear now from our China
cross
Laura they're calling this remarkable
historic it's even trending on social
media here their Channel called wayo um
especially because the mechanical arm
that was used to collect those Rock and
soil samples has put the symbol for
Tonga which is China into the Earth on
the far Side of the Moon they've also
planted the Chinese flag on the far side
of the moon now the reason why
scientists are so excited by this is
because it's very very difficult to
control and even land and get an
aircraft to take off from The Far Side
of the Moon because there's no line of
sight from Earth so what China did was
they launched a satellite which was
there by April and ready for this
Mission and they've used that satellite
to relay messages so for the last two
days the chi six space probe has been
collecting these precious Rock and soil
samples now the other reason scientists
are very interested in this is because
the in previous samples that you can see
the bit of the Moon that you can see
they've collected the samples that look
very volcanic look very like you would
see in Iceland or Hawaii however it is
thought that the rocks on The Far Side
of the Moon could contain traces of ice
now that would mean there is some kind
of source of water on that part of the
Moon the reason scientists get excited
by that is they are hoping one day to
build some kind of space station up
there and it is hoped that perhaps it
could sustain life we're way off that
but right now China believes it's way
ahead when it comes to this kind of
lunar
exploration thanks to Laura for that
right we can speak now to astrophysicist
Professor Quentin Parker from the
University of Hong Kong thanks for
coming on the program
pleasure so what do you make first of
all of just the challenge that has been
successfully completed so far we'll get
on to the rocks in the ice in a moment
but just the logistics of doing what's
been done so far what do you make of it
well it's never been done before in
terms of a a Luna sample return Mission
From The Far Side now China has already
landed on the far side when it did that
uh with chanka 4 that was the first time
that's ever been done as well and now
it's the second time they've gone back
to the far side and this time they've
done it to bring back uh lunar Rock and
soil sample so that is very complicated
as was said by the previous speaker
there's no direct line of sight so you
have to have a relay satellite called uh
cha and that's basically means magpi
bridge and the Chinese love having these
interesting and lovely names for their
missions and that's kind of in a what's
called an L2 orbit around the Moon that
allows a direct line of sight from the
Lander to the satellite from the
satellite back to the Earth so you can
remain in in communication at all times
which is vital for a mission of this
type it's very complicated very
challenging technically they've done it
again and now just like the changer five
which is on the near side they're now
going to be bringing back we hope lunar
Rock from the from the far side rather
than the near side right let's get on to
this rock then how much of it have they
grabbed and what's going to happen to it
now um they probably grabbed about the
same amount as last time with changa 5
because the changa 5 Mission and changa
6 are basically the same in terms of the
intent to go to the moon and bring back
Sample about 2 kilg is what they expect
to bring back okay and what happens to
it now when it's back on
Earth well I mean assuming they can get
it back to Earth um first um there's
still a few Hairy Bits to go they you
know they've gone back from Luna uh from
the from the surface of the Moon in into
the spacecraft that land bring it back
to the Earth they're going to transfer
the sample into the the module that
re-entry vehicle that actually mustn't
burn up in the atmosphere and come back
safely to to land in in Mongolia and
once all of that happens if it all does
happen because there's pretty scary
parts there uh then they'll just uh very
carefully like the Americans did with
the um asteroidal material that they
recovered carefully unpack and and
extract the material from within the
Lander and what will they be looking
for well as was said previously I mean
The Far Side of the Moon looks very very
different to the near side on the near
side of have all these Mar you know like
Sea of Tranquility which big lava feels
from volcanic activity that's pretty
much absent from The Far Side of the
Moon for reasons aren't completely
understood what you see on the far side
is a much you know very crated terrain
lots of bombardment happened like on the
near side but it hasn't been uh washed
over by volcanic Lakes like it has on
the near side and so we think that
geology is very different and down in
the South Pole there are craters there
which have high walls protected from
sunlight at all times and in those
craters we think there might be water
ice and helium and other precious
materials which will be of great use to
to Future exploration of the Moon and
even to habitation interesting and what
does all this as you you've you've
highlighted again the caveats not over
yet not safely backed yet we appreciate
those caveats but but if we presume that
that does all go swimmingly what does
this do uh do you think for the
country's space
Endeavors um well China
uh Moon space fairing events have been
going gang busters I would say for about
10 years you know they've had a very
successful changa series of Luna
missions they've also gone to Mars
they've also built a space station and
about to put up a 2 meter class optical
telescope like the Hub but with a field
of view 350 times larger so there's lots
of things happening in the Chinese space
program this is just one of the most
exciting so the the Luna missions have
uh haven't failed they've all been
successful so far and every body all any
lunar scientist any geologist worth his
salt or her salt will be praying that
this sample comes back in a pristine
condition so it can be studied and so
you know it's going to be a veritable
Cornucopia of scientific Delights I
think that's going to come out from the
geology of these different samples from
the far side and the near side and these
samples are being shared I mean we got a
sample of Hong Kong you you know and my
deputy director Jo machowski who's
American worked a lot with NASA he's
going to be he's working with that near
side sample right now and we hope to get
a Far Side sample too and around the
world I think Manchester University's
got access to the changer 5 near side
Moon Rock so you know it's not just
China here I mean it's International
collaboration which is great to
absolutely fascinating Professor queny
Parker thank you very much for
explaining so clearly thank you it's a
pleasure thank you very much
