China’s recent achievement in space exploration marks a groundbreaking milestone in laser technology. The nation successfully fired a precision laser across over 80,000 miles of space to bounce it off a satellite orbiting the Moon during daylight. This feat showcases China’s relentless pursuit of technological advancement and strengthens its position in the global space race. The experiment, conducted by the Deep Space Exploration Laboratory (DSEL), plays a crucial role in China’s ambitious plans to establish a permanent lunar presence by 2035. This article delves into the intricate details of this remarkable achievement and its implications for future space missions.
Precision and Mastery: The Art of Satellite Laser Ranging
Satellite laser ranging is considered the gold standard for determining satellite orbits with pinpoint accuracy. The process involves firing nanosecond pulses from ground stations, which bounce off retroreflectors on spacecraft and return to reveal the distance down to centimeters. While this technique is routine for low-Earth satellites, the challenge multiplies when dealing with the Earth-Moon distance, especially under daylight conditions. China’s recent success in overcoming solar background noise to achieve accurate measurements during daylight expands the limits of this technology significantly.
This remarkable precision is likened to “aiming at a sub-millimeter target—essentially a single hair—from over 6.2 miles away.” By achieving such accuracy, China can now gather orbital data whenever the Tiandu-1 satellite passes within view, enhancing the frequency and reliability of measurements. This development is crucial for the planned Queqiao constellation, which aims to provide continuous communications and navigation support for various lunar missions.
A Step Closer to China’s Lunar Ambitions
China’s space endeavors are part of a more extensive plan to establish a permanent foothold on the Moon. The Tiandu-1 satellite, along with Tiandu-2 and the Queqiao-2 relay satellite, form the backbone of China’s lunar exploration infrastructure. These satellites have already delivered detailed images of the lunar surface and demonstrated successful cross-link communications, paving the way for more ambitious missions.
The China National Space Administration (CNSA) has set an ambitious timeline, targeting a crewed lunar landing by 2030. The construction of the International Lunar Research Station, a collaborative effort with Russia, is expected to begin by 2035. Laser ranging technology will play a pivotal role in various aspects of lunar exploration, including approach-and-landing guidance and the coordination of rover fleets exploring the Moon’s surface.
Expanding the Horizons of Earth-Moon Links
With the success of the daylight laser ranging experiment, DSEL plans to extend daytime trials to longer ranges and higher repetition rates. This advancement will integrate more seamlessly into routine deep-space operations, enhancing the reliability of Earth-Moon links. The experiment follows the successful 2024 launch of Chang’e-6, which returned soil samples from the Moon’s far side, underscoring the importance of robust communication and navigation systems in space exploration.
Beyond laser technology, China is exploring other innovative solutions to support its lunar ambitions. The CNSA anticipates the need for a comprehensive space-traffic management system to handle the estimated 100,000 satellites in low Earth orbit by the decade’s end. In collaboration with Russia, China is also evaluating nuclear reactors and alternative power sources for the International Lunar Research Station under the Chang’e-8 mission.
Future Prospects: Challenges and Opportunities
China’s achievements in laser technology and lunar exploration present both challenges and opportunities. The nation’s advancements in space technology could spur increased competition among space-faring nations, potentially leading to new collaborations and innovations. However, the growing number of satellites in orbit also raises concerns about space traffic management and the potential for collisions.
As China continues to push the boundaries of space exploration, the implications for international cooperation and competition remain to be seen. How will other nations respond to China’s rapid advancements in space technology? Will these achievements lead to new opportunities for collaboration, or will they intensify the global space race? The future of space exploration is undoubtedly intriguing, with many questions yet to be answered.

Wow, I didn’t even know you could hit the moon with a laser! 🌕
Are you fucking kidding me? NASA put mirrors on the moon back in 1969 and hit them with a laser to accurately measure the distance between earth and the moon.
Yes, exactly!
So um. Obviously rither the moond closer than they told us or A.I needs to not be used to make news articles cause 80,000… the moons 200,000 miles away. Slightly further than the life time miles on an old car at 200,000 miles… what idiot made this article with such inaccurate well known information.
China sure is making strides in space technology, huh?
How will this affect international relationships in space exploration?
Is this the start of a new space race or just a step in China’s space journey? 🤔
What’s next? Lasers on Mars? 😂
This is amazing. What implications does this have for future space missions?
China’s not messing around. Permanent lunar presence by 2035 sounds ambitious.
Can we expect more countries to join the space race after this?
Mind-blowing precision! A hair from 6.2 miles away? 😲
Why is this significant? Don’t they already have satellites on the moon?
I was taught that the moon was much further away, around 239,000 miles. Why is the satellite only 80,000 miles away?
80,000 miles?! That’s insane!
Is there any chance this could lead to weaponizing space lasers? 🤨
Great read, lots of potential for new space tech. Keep it up!
Hope this doesn’t spark a new Cold War in space.
Does this mean we might see lunar bases in our lifetime?
Really cool stuff, but how does it impact everyday life on Earth?
Lol, I bet the aliens are just as stunned!
Can’t believe they pulled this off in daylight. Impressive!
How does this compare to other countries’ space programs?
Is the moon going to become crowded with all these satellites?
Can this tech be applied to other planets in the future?
Just wait for a movie about this – “Lasers on the Moon” coming soon! 🎬
How long before we see a space traffic jam? 🤷♂️
What does this mean for the future of international space stations?
Does anyone else think this is just a sci-fi movie plot coming to life?
Is it just me, or does this sound like the start of a new sci-fi era?
What is so ‘amazing’? NASA placed Lunar Laser Ranging (LLR) equipment on the moon 50 years ago. So did Russia. Can’t put the Wikipedia link in the comments here so just look for LLR in Wikipedia.
We hit the moon and the reflector on the moon regularly to monitor movement of the moon.
Thank you for the detailed explanation, really puts things into perspective!
Is there any environmental impact from firing lasers into space?
What role does Russia play in China’s lunar plans?
Wow, a permanent lunar presence by 2035? That’s ambitious! 🚀
So, when can we expect a similar feat from other countries?
Isn’t aiming a laser at the moon a bit risky? What if it misses and hits something else? 😂
Absolutely fascinating! Thank you for sharing this incredible achievement. 🚀
Can this technology be used for anything else besides lunar exploration?
China, what a bunch of maroons. 50 + years ago, been there, done that.
And we’ve been funding all of their advancements with our own money and technology
China’s way of showing the world they can hit moving satellites during the daytime with a laser is also China’s way of showing the world that they can hit moving satellites during the daytime with a laser during war. China is moving up fast and letting the world know.
What a stupid article. The author clearly doesn’t understand the subject matter here and just blindly repeated something handed to her without even trying to do her journalistic due diligence and finding supporting evidence.
First of all, the moon is 240,000 miles away. Any object 80,000 miles away is not orbiting the moon, it is orbiting Earth.
Secondly, lasers are not pinprick precise as the article implies. As with all light sources, coherent or not, it will form a cone. All lasers do this. It’s called beam divergence, and is generally between 1 and 10 milliradians. The larger and more powerful the laser, the greater its beam divergence. Generally speaking, the more powerful a laser is, the wider the aperture must be, and therefore the beam divergence is higher. It’s not at all as the article claims, “iming at a sub-millimeter target—essentially a single hair—from over 6.2 miles away.” At that distance, and being generous with a 5 milliradian beam divergence, it’s more like “shining a giant spotlight 6.2 miles away and lighting up an area 150 feet wide and finding that a single hair is within that 150 foot circle.” At a more reasonable 10 milliradians for something as powerful as a lunar ranging beam, it would be about 330 feet.
And as for the daytime claim? The Apache Point observatory does it routinely from the ground during daylight. This article talks of an event that is not groundbreaking. It’s not novel. It’s not even worthy of attention. It’s just propaganda.
Finally, the Chinese bots with their fake fawning and stupid rhetorical questions are obvious shills. So is the article author.
What a stupid article.
Trash article. That’s not how lasers work. At 6.2 miles the cone would be 330 feet across, not the width of a human hair. At 80,000 miles the cone would be almost a mile wide. With the actual distance to the moon 240,000 miles the cone would be 2.4 miles wide
Just gonna leave this right here🫳
I don’t know shit about lazers, distance to the moon, who the “supreme” leader is over there, and a lot of other shit. But what I do know is that things like this are subtle hints at what’s to come. And most of the time I’ve already been here. How many movies are coming true right now? How many already have? What seems like irrational bullshit is one of two things. Something that’s already been developed, and now bringing the public up to speed. Or crowd sourcing for the way to achieve it. FOR FREE. Their just showing us how well be kept j line while they live on the moon and Mars. Which has probably been a thing. Total recall?

If you’re going to use AI to generate illustrations, at least make sure they make sense.
This is damn near an example of dead internet theory right here. A seemingly AI written article with a bunch of AI written comments responding to it. This reeks of propaganda and is just embarrassing. Need to figure out a way to block this website so I don’t get recommended articles from it in the future.
