1
To nearly everyone, the Moon appears to be a sterile, gray, unchanging world.
2
But while the Moon has remained largely unchanged during human history, our own understanding of it has evolved dramatically.
3
Thanks to new observations, we now have not only unprecedented views of its surface, but a whole new tour of the Moon that shows how both it
4
and other rocky planets in our solar system have been shaped over billions of years.
5
We'll start with one of the largest impacts, Oriental Basin, a feature that's as wide as the distance from New York City to Cincinnati.
6
Using new elevation measurements, we can clearly see the effects of what is likely the last giant impact event in lunar history,
7
with its outer mountain rings rising many kilometers above the lowest points inside the crater.
8
The interiors of some craters in the Moon's polar regions, like Shackleton, haven't seen sunlight in over two billion years.
9
However, new measurements have created our best yet maps of these types of craters, allowing us to see deep into the shadows of this surprisingly
10
young-looking impact crater in the south that's more than twice as deep as the Grand Canyon.
11
Some impacts are invisible for other reasons.
12
Although the ancient South Pole-Aitken Basin is difficult to see from orbit because it is so large,
13
new LRO topography maps reveal the largest impact basin in the Earth-Moon system, measuring several kilometers in depth and around 2,500 kilometers in diameter.
14
Only the Hellas Basin on Mars rivals it in size.
15
One of the youngest large-scale impacts on the Moon is the Tycho Crater.
16
This fresh crater may have formed only 108 million years ago, when dinosaurs roamed the Earth.
17
We now also have an extreme close-up view of the crater's central peak, revealing a a mountain with sharp edges,
18
building-sized rocks, and a central boulder about the size of a baseball stadium.
19
The Aristarchus Plateau is another recent lunar formation that has long interested scientists and astronomers.
20
The crater itself, formed in the same era as the Tycho Crater, and what appear to be snaking river valleys, were actually carved by ancient lava flows.
21
Next, we arrive at Mare Serenitatis on the near side of the Moon.
22
In December of 1972, the crew of Apollo 17 landed in the Taurus-Littro Valley,
23
marking the last time humans have visited the surface of the Moon.
24
With images from LRO's narrow-angle camera, we can clearly see the evidence of that visit.
25
In this image, you can easily see the base of the lunar lander, along with the lunar rover, parked far from the blastoff zone.
26
You can also clearly see the astronaut trails and the wheel tracks left on the lunar surface.
27
We now head to the far side of the Moon, which cannot be seen from Earth.
28
Our first stop is the Compton-Belcovich region, which shows evidence for young volcanic activity in the Far Side Highlands.
29
This feature is unique not only because it is isolated from other volcanoes in the area, but also because it is located nowhere near the Maria,
30
where volcanoes are usually found.
31
Also, on the Far Side, we find the Jackson Crater, which like the Tycho Crater on the near side has an extensive and complex ray system.
32
In fact, this crater is often considered to be like a twin to Tycho.
33
Finally, the Tsiolkovsky Crater stands out as an excellent example of a far side crater filled with a sea of ancient lava, known as a mare.
34
It is particularly interesting to scientists and other observers
35
because of its isolation from other similar craters as well as its beautiful central peak.
36
As we continue to study the Moon, our understanding of it improves, giving us new insights not only into how it has evolved over time,
37
but also how other rocky planets in our solar system have come to look the way they do.
38
With new missions, new instruments and new technologies, we will continue to improve our knowledge of the Moon and better understand the history of our solar system.
39
Thank you.

Why Practice Speaking with This Video?

Learning English with videos like "NASA | Tour of the Moon" offers a unique chance to practice speaking in a scientific, descriptive context—perfect for building clarity and precision. The narrator’s steady, articulate tone makes it ideal for the shadowing technique: repeat phrases aloud as you hear them, mimicking rhythm and intonation. This improves fluency and trains your ear to follow complex ideas. Plus, the video’s mix of geographical terms and historical facts expands your vocabulary in a meaningful way, making "shadow speak" practice both educational and engaging.

Grammar & Expressions in Context

  • Passive Voice for Scientific Description: "The interiors of some craters... haven’t seen sunlight in over two billion years." Passive voice is common in academic speech—practice it to sound more formal and objective.
  • Comparative Structures: "Twice as deep as the Grand Canyon" or "Only the Hellas basin on Mars rivals it in size." These phrases help explain scale; use them to compare objects or ideas clearly.
  • Time References for Historical Events: "Formed only 108 million years ago—when dinosaurs roamed the Earth." Linking events with "when" adds context; master this to connect facts smoothly.

Common Pronunciation Traps

Watch out for these tricky words: Orientale (oh-ree-en-TAH-lee) and Tsiolkovsky (tsyol-KOV-skee) have unique stress patterns. The narrator also uses long, flowing sentences—practice pausing at commas to avoid rushing. For extra help, use a shadowing app to slow down audio and repeat challenging phrases. Focus on words like "topography" (tuh-POG-ruh-fee) and "basin" (BAY-sin)—mispronouncing these can confuse your message. With consistent "shadowspeak" practice, you’ll nail these sounds and speak with confidence.

Grammar in this video

The structures the speaker uses most, with the exact words from the video:

What is the Shadowing Technique?

Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
