@@ramonkroutzHe is colorblind, not blind or deaf. He can read and listen to information about the moon. It’s also part of basic astronomy you learn as a child, the moon is not yellow and it is not made of cheese! It is actually grey. Mind blown 🤯
I recently bought a shower curtain that has a huge 5 foot, real picture of the Moon. Thanks to this documentary I'm now able to identify some of its terrain. Thank you.
The old rule of thumb for aerial photo interpretation is "shadows stab stomach." That is, rotate the image until shadows are pointing toward the viewer. This mitigates visual inversion of terrain and the true 3-D effect thus appears. PS I learned this so much more from fabulous old profs in Dartmouth's geography classes now five and more decades ago. So long ago, ERTS (renamed LANDSAT) satellites were still months away from first being lifted into Earth orbit. )
or from old military image analysis procedures to identify camouflaged buildings. My Dean of Engineering had one in his office and let us students read it.
Absolutely fantastic! Love how the images of places on earth are placed for scale. This makes for such a better understanding regarding the moon’s topography. Love this!
These side views in 4K are spectacular. I have been waiting all my life for aircraft-style views of our Moon.

When I was a little child, children were often told the moon was made of green cheese. One night I was out with my Dad, we took some time to examine and admire the sky. The moon was the object of my attention. After some thought I ask, "Dad, if the moon is made of green cheese why is it grey." He looked at the moon for a moment then said, "It was green when I was young, but now the moon is so old it is covered with mold." As I was still young enough to be awed by such wise wisdom I was very much impressed.
@@Sashazur that sounds like an explanation right up my dad's alley (or in modern terms, part of his mind canon) To bad i never thought to ask about all the black and pictures and movies.
@@koenwijnen8278 you must be a millennial to think such a thing would posion a child's mind. • How exactly would you describe what the moon is made of to a little child? • Do you also think it is poisoning a child's mind for them to watch cartoons or children's programing? • How about children having imaginary friends? I'm sure it will be amusing to hear your insight or lack there of on my questions. But don't worry my mind wasn't poisoned. I'm a retired medical professional. That means I'm college educated in the field of human anatomy, physiology and mental health. As well for hobbies I'm interested in astronomy, geology, phytomedicine. As I became an older child I felt rather grownup when I knew "grown-up" answers to my questions. The childhood answers became fond memories as I realized that as a little child the technical and scientific answers were beyond what a child should be burdened with.

Lunar crater reversal is an interesting phenomena . Scott's Polar expedition in the early 20th Century had trouble seeing footprints ahead of them as indentations in the snow but instead saw raised mounds they avoided in case they tripped. This was when a low Sun cast shadows in a certain direction. Walking in the other direction they had no problems seeing the footprints as the indentations they were. Another useless litte fun fact.

@@truthsRsung Apollo used Hasselblad medium-format cameras that created a 60x60 mm negative. March To the Moon has those negatives scanned at 12000x12000 pixels, i.e. 144 MP, about equal to the best digital cameras you can buy today.
Beautiful narration, music, and editing as always. Luna doesn't get the love it deserves, and you guys make it easier for regular people to enjoy its majestic beauty through the eyes of Earth's space agencies.
Is there a geological map of the moon or is it just a ball of the same rock everywhere? Also, are there any colours there? It is an undeniably beautiful sight, I often wonder if it is as vivid in colour as say, the lava fields in Tenerife?
In ‘69 when Neil, buzz and Mike went to the moon, I was nine. Years later, I asked my mother why did we stop the moon missions? She said: the public got bored with the moon. It was just a bunch of rocks. If Buzz Aldrin would’ve found a gold nugget, it would have been a different story. Nobody would remember the name Neil Armstrong.

By so doing, you experienced what Galileo experienced, and I admire that. I used to sketch open clusters and the like, looking for "mini constellations," but did so through a reflector that I bought. Look through the index of a "Sky and telescope" magazine and find yourself a small reflector or satellite scope to view the Moon and carry on. . . best of luck.
@@David-gh6vp thank you, i will do that.. I know a telescope doesn't cost much but I gotta prioritize.. I've been enjoying theoretical science recently but I'm also aware of all the mysterious awesomeness awaiting in the night sky! btw have you ever spotted Andromeda? Is it in Orion?!
Wait at 4:55 is the light area higher or lower in elevation? The rotation doesn't matter, it looks the same to me either way(light region is higher elevation)

Lunar Crater Radio Telescope (LCRT) aims to build a radio telescope on the far side of the moon. NASA propose to deploy a wire mesh using wall-climbing DuAxel robots in a 3-5 km diameter crater, with a suitable depth-to-diameter ratio, to form a parabolic reflector with a 1 km diameter. LCRT will be the largest filled-aperture radio telescope in the Solar System; larger than the former Arecibo telescope (300 m diameter, 3 cm - 1 m wavelength band, 0.3-10 GHz frequency band) and the Five-hundred-meter Aperture Spherical radio Telescope (FAST) (500 m diameter, 0.1-4.3 m wavelength band, 60-3000 MHz frequency band). The objective is to track the evolution of the neutral intergalactic medium before and during the formation of the first stars, which is consistent with priorities identified in the Astrophysics decadal survey.
the fact that you've seen the moon a thousand times in your lifetime is true unless you live in scotland, they have yet to discover it due to the everlasting clouds and rain
For those who don't know the late Wallace (Wal) Thornhill describes these rills as electrical in nature coming from electrical discharges between planets and it makes so much more sense. Check out (Symbols of an Alien Sky) Episode 2 The Lightning Scarred Planet Mars) Narrated by David (Dave) Talbott and get a better picture of what craters and rills are all about.
A bit cringey lol. Aristarchus (eh-·ruh-staar-kuhs)...the Greek mathematician and astronomer that first noted our heliocentric solar system. He was the first to say that the Sun, NOT the Earth, was the center of our 'universe'.
A few things which make me think they faked the landings; BTW - I taught the NASA myth for 20 years and it only after going down the 9/11 rabbit hole that I started seeing evidence to the contrary. My first model was of the Saturn V and I made it in 1970 when I was 10 years old. I lived and breathed the Apollo Missions for the next 40 years. Just answer some of these undeniable facts and I can go back to my model building. 1 Vacuum and Dust - sealing up doors, suit/helmet/gloves with so much dust - can't see how they do and no transcript explains 2 Photographic film - (kodak says that it was regular Ektachrome, same kind used in the spy satellites used in the late 60's and early 70's) no signs of damage by degassing, radiation, extreme temperature range 3. Amazing track record: - The number of tests required now before a crew is allowed to travel is ridiculous Only 13 actual launches of Saturn 5 - 3 without crews 6 successful LM landings and lunar launches/docking. ( only actual practice of LM was when Apollo 10 crew detached, practice manuevering crafted and docked) 100 percent survival and with no immediate or chronic health problems - All Apollo Splash downs were within 4 km of predicted LZ despite skip re-entry techniques - Apollo 13 was 1.85 km from predicted. Apollo 8 was the 4th launch of a Saturn V and was planned to orbit Earth and instead it left Earth orbit for the first time, tried lunar orbit insertion for the first time, return to Earth as scheduled and landed 2 km from pick up site. They were also the first to test heat shield with Lunar return speeds of 40 000 km per hr, where as the Low Earth Orbits re entry speeds are only 28 000 kms . 4. On schedule - 8 years and 2 months from sub-orbital flight lasting 15 minutes to actually walking on the moon. Not bad for a time when 8 tracks, Beatles, Andy Griffith show were all the rage, computers were the size of boxcars and disco had yet to happen. 5. 1000's of Beautiful framed pictures - despite no view finder, no bracket shots . 6. Apollo solved how to build a dependable heavy lift rocket, space suits that worked for excursions, a LM that worked every time, a spaceship that regulated the heat and protected from cosmic radiation and a heat shield that could handle 40 000 km /hr re-entry speed. Unfortuately they are still re-inventing these things 55 years later. 7. There has been no 3rd party confirmation of the landing sites. China and India if they have confirmation of a fraud are keeping it on the down low. NASA's Lunar orbital pictures don’t count. 8. Laser reflectors on the moon isn’t proof. Unmanned probes can do this. 9. Lost - Most original evidence, telemetry and video tapes has been lost, the rocks are still being carefully looked after but I am told it is virtually impossible for a person to do a forensic analysis to confirm providence because you have to apply to get them and explain why you want them. 10. The furthest away from Earth’s surface since Apollo’s moon missions has been when they fixed the HST and were 570 kms away from Earth in 1993 11. 6 trips to the moon and of the thousands of photographs, only a handful of them show Earth, while none show the stars. Oh Yeah ! would it have killed them to leave a telescope on the moon?
0:03 As a Cinematographer for 26 years and camera assistant, knowing professional photography, I was able to video both The Sun and The Moon traveling through the clouds which redefines the true facts regarding what was told. Both sun and moon are local and smaller. We have been lied to with gross disinformation.
My guess at 24:00 as to why the area around newer craters get cooler quicker is that the regolith has being disturbed enough to make it a bit more porous and less compacted, reducing the insulation that more compact/old regolith provides and so releases it's heat more easily (A bit like tilled earth). Where as the immediate impact crater itself has being compressed, providing better insulation. And the undisturbed regolith surrounding the cooler (tilled) areas have gradually compressed over time, undoing any "tilling" from previous disturbances.
I would say it's the opposite :) New impacts are probably more compacted as the heated / molten rock when it solidified formed a very compact and dense mass distribution. Keep in mind that there's no atmosphere, so heat can only be lost through conduction and radiative cooling. Compact material can transfer heat through the material more easily than when it becomes porous. The constant heating and cooling over a lunar day (month) would over time make the material more and more porous as different material will expand and contract slightly different leaving "cracks" in the material. So a porous / sponge like structure could trap heat for longer as heat can mainly travel through conduction and the more space is in between, the less heat can be transferred. Though I'm not a geologist and this is just a wild assumption. Though keep in mind that thermos cans (vacuum flasks) trap the heat by having a vacuum space between the inner and outer walls. Having cracks within a material on the moon would have a similar effect. Unlike here on earth where we have an atmosphere, no air would fill the cracks on the moon. The more disconnected the material is, the less conduction would happening.
Oh I agree! The pockets of vacuum inside the regolith offer great insulation for trapped heat/cold. We also need to take into account the composition, speed and angle of what impacted the moon~ Though more pertinent is the variable of surface area, and given that it's infrared radiation that's escaping, it will emit out and bounce wherever it can, even without air as a medium, it just takes a lot longer in a vacuum, though geologically not very long at all. And for example with the heatsinks in satellites, that are used to keep it's equipment from overheating (due to the issue with a lack of air to steal away its heat); typically the radiators they use have to be densely packed with honeycomb or ridges, with as much surface area as possible, with as little material as possible, and of course needs to be faced away from the sun. And so in relation to why the crater mentioned in the video might have such a great variance of heat from the centre and unaffected surroundings; compared to the rim. We can assume the immediate impact spot will be dense due to compression and/or heat. While the surrounding area will be cracked and scattered, the release of heat will vary greatly the further from the centre you go. And given the looser material will generally still retain it's heat well enough in a vacuum, it will lose its heat much faster than any undisturbed, settled or impacted regolith. Which could well explain the ring of colder material mentioned in the video. Much like the honeycomb in our satellites radiator, the disturbed but uncompacted material at the rim will offer many more escape routes for the radiation to bounce out of. While the upper layers of particulate also offer some modicum of protection from direct sunlight to those below, providing the highest net loss of heat comparatively. But yeah, this is all speculation, still neat to think about!
24:10 could it be something that is turning into ice after the sun sets and thawing after sunrise? Not necessarily water ice but something else that is freezing up?? This is very interesting but probably very simple
Because the moon has no atmosphere, liquids can’t exist at the surface: when e.g. water ice reaches its melting point, it sublimates to a gas directly instead of melting into a liquid.
Supercut of the LRO series! 5 episodes into one. I hope you enjoy some of the coolest sights and weirdest mysteries the Moon has to offer :)

Being colorblind, I’ve an appreciation for the grayscale appearance of the Moon. It happens to match a large portion of my wardrobe.
You know, I have seen articles with severely blown up pictures of spacecraft on the Moon, but I’ve never seen as many great shots such as the ones you have compiled. I’m sure I’d be able to find several from NASA’s archives, I just haven’t been so inclined, so it was nice that you included so many.
Great work as always, Mr. Astrum. Your channel is very, very informative and your work is so inspiring and appreciated.
Being colorblind how do you know the moon is grey
@@ramonkroutzHe is colorblind, not blind or deaf. He can read and listen to information about the moon. It’s also part of basic astronomy you learn as a child, the moon is not yellow and it is not made of cheese! It is actually grey. Mind blown 🤯
I recently bought a shower curtain that has a huge 5 foot, real picture of the Moon. Thanks to this documentary I'm now able to identify some of its terrain.
Thank you.
The old rule of thumb for aerial photo interpretation is "shadows stab stomach." That is, rotate the image until shadows are pointing toward the viewer. This mitigates visual inversion of terrain and the true 3-D effect thus appears.
PS I learned this so much more from fabulous old profs in Dartmouth's geography classes now five and more decades ago. So long ago, ERTS (renamed LANDSAT) satellites were still months away from first being lifted into Earth orbit. )
or from old military image analysis procedures to identify camouflaged buildings. My Dean of Engineering had one in his office and let us students read it.
He never said which way it was inverted though. All i could see was the smooth parts were valleys.
what a great comment! makes sense.

When I was a little child, children were often told the moon was made of green cheese. One night I was out with my Dad, we took some time to examine and admire the sky. The moon was the object of my attention. After some thought I ask, "Dad, if the moon is made of green cheese why is it grey." He looked at the moon for a moment then said, "It was green when I was young, but now the moon is so old it is covered with mold." As I was still young enough to be awed by such wise wisdom I was very much impressed.
It’s like Calvin’s dad explaining why the world used to be in black & white.
@@Sashazur that sounds like an explanation right up my dad's alley (or in modern terms, part of his mind canon) To bad i never thought to ask about all the black and pictures and movies.
Kind of sad to poison a childs mind like that
@@koenwijnen8278 you must be a millennial to think such a thing would posion a child's mind.
• How exactly would you describe what the moon is made of to a little child?
• Do you also think it is poisoning a child's mind for them to watch cartoons or children's programing?
• How about children having imaginary friends?
I'm sure it will be amusing to hear your insight or lack there of on my questions.
But don't worry my mind wasn't poisoned. I'm a retired medical professional. That means I'm college educated in the field of human anatomy, physiology and mental health. As well for hobbies I'm interested in astronomy, geology, phytomedicine.
As I became an older child I felt rather grownup when I knew "grown-up" answers to my questions. The childhood answers became fond memories as I realized that as a little child the technical and scientific answers were beyond what a child should be burdened with.

You were not overselling it with that title! What a stunning educational vid, belongs in every science center's movie rotation.
Lunar crater reversal is an interesting phenomena . Scott's Polar expedition in the early 20th Century had trouble seeing footprints ahead of them as indentations in the snow but instead saw raised mounds they avoided in case they tripped. This was when a low Sun cast shadows in a certain direction. Walking in the other direction they had no problems seeing the footprints as the indentations they were. Another useless litte fun fact.
Thanks!

Lunar Crater Radio Telescope (LCRT) aims to build a radio telescope on the far side of the moon. NASA propose to deploy a wire mesh using wall-climbing DuAxel robots in a 3-5 km diameter crater, with a suitable depth-to-diameter ratio, to form a parabolic reflector with a 1 km diameter. LCRT will be the largest filled-aperture radio telescope in the Solar System; larger than the former Arecibo telescope (300 m diameter, 3 cm - 1 m wavelength band, 0.3-10 GHz frequency band) and the Five-hundred-meter Aperture Spherical radio Telescope (FAST) (500 m diameter, 0.1-4.3 m wavelength band, 60-3000 MHz frequency band). The objective is to track the evolution of the neutral intergalactic medium before and during the formation of the first stars, which is consistent with priorities identified in the Astrophysics decadal survey.

A few things which make me think they faked the landings; BTW - I taught the NASA myth for 20 years and it only after going down the 9/11 rabbit hole that I started seeing evidence to the contrary. My first model was of the Saturn V and I made it in 1970 when I was 10 years old. I lived and breathed the Apollo Missions for the next 40 years. Just answer some of these undeniable facts and I can go back to my model building.
1 Vacuum and Dust - sealing up doors, suit/helmet/gloves with so much dust - can't see how they do and no transcript explains
2 Photographic film - (kodak says that it was regular Ektachrome, same kind used in the spy satellites used in the late 60's and early 70's) no signs of damage by degassing, radiation, extreme temperature range
3. Amazing track record: - The number of tests required now before a crew is allowed to travel is ridiculous
Only 13 actual launches of Saturn 5 - 3 without crews
6 successful LM landings and lunar launches/docking. ( only actual practice of LM was when Apollo 10 crew detached, practice manuevering crafted and docked)
100 percent survival and with no immediate or chronic health problems -
All Apollo Splash downs were within 4 km of predicted LZ despite skip re-entry techniques - Apollo 13 was 1.85 km from predicted.
Apollo 8 was the 4th launch of a Saturn V and was planned to orbit Earth and instead it left Earth orbit for the first time, tried lunar orbit insertion for the first time, return to Earth as scheduled and landed 2 km from pick up site. They were also the first to test heat shield with Lunar return speeds of 40 000 km per hr, where as the Low Earth Orbits re entry speeds are only 28 000 kms .
4. On schedule - 8 years and 2 months from sub-orbital flight lasting 15 minutes to actually walking on the moon. Not bad for a time when 8 tracks, Beatles, Andy Griffith show were all the rage, computers were the size of boxcars and disco had yet to happen.
5. 1000's of Beautiful framed pictures - despite no view finder, no bracket shots .
6. Apollo solved how to build a dependable heavy lift rocket, space suits that worked for excursions, a LM that worked every time, a spaceship that regulated the heat and protected from cosmic radiation and a heat shield that could handle 40 000 km /hr re-entry speed. Unfortuately they are still re-inventing these things 55 years later.
7. There has been no 3rd party confirmation of the landing sites. China and India if they have confirmation of a fraud are keeping it on the down low. NASA's Lunar orbital pictures don’t count.
8. Laser reflectors on the moon isn’t proof. Unmanned probes can do this.
9. Lost - Most original evidence, telemetry and video tapes has been lost, the rocks are still being carefully looked after but I am told it is virtually impossible for a person to do a forensic analysis to confirm providence because you have to apply to get them and explain why you want them.
10. The furthest away from Earth’s surface since Apollo’s moon missions has been when they fixed the HST and were 570 kms away from Earth in 1993
11. 6 trips to the moon and of the thousands of photographs, only a handful of them show Earth, while none show the stars. Oh Yeah ! would it have killed them to leave a telescope on the moon?
0:03 As a Cinematographer for 26 years and camera assistant, knowing professional photography, I was able to video both The Sun and The Moon traveling through the clouds which redefines the true facts regarding what was told.

Ckmy ch
My guess at 24:00 as to why the area around newer craters get cooler quicker is that the regolith has being disturbed enough to make it a bit more porous and less compacted, reducing the insulation that more compact/old regolith provides and so releases it's heat more easily (A bit like tilled earth). Where as the immediate impact crater itself has being compressed, providing better insulation. And the undisturbed regolith surrounding the cooler (tilled) areas have gradually compressed over time, undoing any "tilling" from previous disturbances.
I would say it's the opposite :) New impacts are probably more compacted as the heated / molten rock when it solidified formed a very compact and dense mass distribution. Keep in mind that there's no atmosphere, so heat can only be lost through conduction and radiative cooling. Compact material can transfer heat through the material more easily than when it becomes porous. The constant heating and cooling over a lunar day (month) would over time make the material more and more porous as different material will expand and contract slightly different leaving "cracks" in the material. So a porous / sponge like structure could trap heat for longer as heat can mainly travel through conduction and the more space is in between, the less heat can be transferred.
Though I'm not a geologist and this is just a wild assumption. Though keep in mind that thermos cans (vacuum flasks) trap the heat by having a vacuum space between the inner and outer walls. Having cracks within a material on the moon would have a similar effect. Unlike here on earth where we have an atmosphere, no air would fill the cracks on the moon. The more disconnected the material is, the less conduction would happening.
Oh I agree! The pockets of vacuum inside the regolith offer great insulation for trapped heat/cold.
We also need to take into account the composition, speed and angle of what impacted the moon~
Though more pertinent is the variable of surface area, and given that it's infrared radiation that's escaping, it will emit out and bounce wherever it can, even without air as a medium, it just takes a lot longer in a vacuum, though geologically not very long at all.
And for example with the heatsinks in satellites, that are used to keep it's equipment from overheating (due to the issue with a lack of air to steal away its heat); typically the radiators they use have to be densely packed with honeycomb or ridges, with as much surface area as possible, with as little material as possible, and of course needs to be faced away from the sun.
And so in relation to why the crater mentioned in the video might have such a great variance of heat from the centre and unaffected surroundings; compared to the rim.
We can assume the immediate impact spot will be dense due to compression and/or heat.
While the surrounding area will be cracked and scattered, the release of heat will vary greatly the further from the centre you go.
And given the looser material will generally still retain it's heat well enough in a vacuum, it will lose its heat much faster than any undisturbed, settled or impacted regolith.
Which could well explain the ring of colder material mentioned in the video.
Much like the honeycomb in our satellites radiator, the disturbed but uncompacted material at the rim will offer many more escape routes for the radiation to bounce out of. While the upper layers of particulate also offer some modicum of protection from direct sunlight to those below, providing the highest net loss of heat comparatively.
But yeah, this is all speculation, still neat to think about!
About damn time! QUALITY RESOLUTION. No more 120p
Wonderfull video. Thanks for thee work
Fascinating! Such beautiful imagery and interesting facts and theories. Learned more about moon craters than I already knew. Thanx.

This is the best video of the moon I have seen, thank you.
At timestamp 28:37 why is there a city bus (grey in color) near the top of that steaming mound of rocks?
24:10 could it be something that is turning into ice after the sun sets and thawing after sunrise? Not necessarily water ice but something else that is freezing up?? This is very interesting but probably very simple
Because the moon has no atmosphere, liquids can’t exist at the surface: when e.g. water ice reaches its melting point, it sublimates to a gas directly instead of melting into a liquid.
So, did anyone notice the "city" at 17:29 in the video? I know it's not really on the moon, but I'm curious what it is supposed to mean!!
