Chang’e 4 Mission’s New Images Illuminate the Far Side of the Moon

February 26, 2020 posted by

China’s Chang’e-4 lander was the first
spacecraft to make a soft landing on the far side of the moon back in
January of 2019. To mark its one year anniversary, the Chinese
Academy of Sciences released a trove of data and photos of the rarely-seen
side of the moon. But aside from taking pretty pictures, what
has Chang’e-4 been doing up there? Well, the first notable thing it’s done
is just survive for a year. The original design life of the lander’s
rover, Yutu-2, was just 3 months. That means the little six-wheeler has been up
there kicking moon dust for four times longer than expected. Not bad, considering the lander and rover were
modified spares the China National Space Administration had on hand in case the Chang’e-3 mission
was unsuccessful. The longevity is also impressive
when you remember the challenges of working on the moon. One full day-night cycle on the moon is about
29 and a half days, so that’s over 14 days of continuous sunshine followed by more than
14 days of darkness. When the long night comes, Chang’e-4 and
Yutu-2’s solar panels don’t generate enough electricity to run its instruments and systems. The crafts have to power down and hibernate
for almost two weeks, just staying alive thanks to onboard radioisotopic heat sources. Basically, a nuclear powered electric blanket. Compare that long night to Mars, where rovers
have to deal with a full day-night cycle that’s only about 40 minutes longer than a day on Earth. But it’s not just the long, cold, lonely lunar
nights that threaten the mission. High noon on the moon is also hot enough to
damage the rover, so it shuts down for about six days at a time while the sun is directly
overhead, heat-blasting it. That’s right: it takes a little nap in the
middle of the day. I never thought I could relate to a spacecraft so much. Sleeping as much as an average teenager is
part of what’s allowed the Yutu-2 rover to survive as long as it has. Yutu-1, the rover it’s almost identical
to, remember, short circuited and conked out on just the second lunar day. Meanwhile, Yutu-2 set a record for longevity
back in November, and is still going strong. So don’t let anyone make you feel guilty
about needing a nap. It’s called self-care. The longer the rover and lander survive, the
longer both can perform experiments with the suite of instruments they carry. Yutu-2 has been studying the lunar regolith
as it rolls along with Lunar Penetrating Radar that can see more than 100 meters down, and
a Visible and Near-infrared Imaging Spectrometer that analyzes the mineral composition
at the surface. Data from these instruments have shown that
the Von Karman crater where Chang’e-4 touched down has thicker regolith than the near side
of the moon, and the spectrometer has detected minerals that appear to have come from the
mantle below the moon’s crust. Continued study and analysis could lend insights
into how the moon evolved. The lander itself is taking measurements of
radiation levels on the moon, and the same instrument can be used to measure the amount
of water in the local lunar soil. However the experiment I am most excited about
is the one that really takes advantage of Chang’e-4’s unique location. The lander’s Low Frequency Spectrometer
is made up of three 5 meter long antennae that are observing low-frequency waves from
the sun, the lunar ionosphere, interplanetary space, and galactic space. It can do this in the relative radio quiet
on the far side of the moon, since the moon’s body blocks the noisy signals we’re constantly
beaming off from Earth. Unfortunately the antennae only deployed last
November, so there’s just not enough data yet. Maybe on Chang’e-4’s two-year anniversary,
after a lot more naps, it’ll have another exciting update for us. While Yutu-2 has set the record for longest
time driving on the moon, the record holder for distance belongs to the soviet rover Lunokhod-2. Thanks for watching, don’t forget to subscribe

  30. SotCRules says:

    Wait…it was launched in December of 2018, and was only expected to survive for 3 months, but didn't deploy the antennae until this past November? Were there some complications that led to a delay in their deployment or did they actually launch a rover with instruments they didn't expect to use? O_o

    Stay thinking that you are superior to the Chinese and do not recognize China's technological advancement, the US will be left behind without realizing it.

    ….how is it getting that data to us?

  43. Alexander Taylor says:

    So cool. Well never be able to see the far side of the Moon from here on Earth. Good to know though, that people are no longer referring to it as the dark side of the Moon. Small regions are never dark. Interesting

    But can it run Crysis?

    Why in the heck are we praising Chinese accomplishments? Does anyone remember what exactly the Chinese government is and what they are doing to their own people? Putting aside all the horrible things that they are doing to America as a nation.. C'mon what are they really doing up there?

  68. ExopMan says:

    3:16 …So the antennae deployed nine months after C4 landed when the rover's lifetime was estimated to be three months?

    Thank you for calling it the "Far Side of the Moon." Some people say the "DARK Side of the Moon," even Dr. Who (William Hartnell), and THAT is supposed to be an educational SCIENCE show.

    Heads up people, the only way China/CPC was able to achieve this, was to force every company that wants to do business in China to give up all of there data. Next they extorted more info from our college professors and paid them to comment treason, then they gave that data to CPC companies to create the Chang'e 4.
    Thanks everyone.

  84. Thomas Tarrants says:

    Quick correction — Chang'e 4's radio science experiment's antennas deployed the day it landed. The radio astronomy experiment that only recently deployed in November was the Dutch experiment on the Queqiao relay satellite.

    Confucius once said. First deity revealing hidden side of Moon to humanity, would prove to be our universes genuine makers.
    I can then add that since we had to finally go look and see what hidden side of Moon looked like for ourselves.
    Obviously anyone in past claiming to be such powerful all knowing deities, yet failing to do so. Only proved themselves false.

    Where are the new images?

    Where are the photographs you all talking about, I haven't seen not one of them yet, bet you anything they're fake or scrub over.

  93. Darren Marquis says:

    Click bait! I actually thought the title said (led me to believe) we might actually see an image!?!?
    Well at least they called it the ‘far side’ and not the ‘dark side’. It’s only dark for 14 days! But we all know that!

  94. r d says:

    I like you commentary, and enthusiasm.

  95. Bill Kerr says:

    So the Chinese released a trove of data. I'm not going to show it to you or give you a link to go and see it but here's my voice saying what instruments they used to discover the data they released that I'm not showing you or telling you about. Here, have some lovely B-roll animations.
    EDIT: Here's the link to download data from the source:
