    China Probe
AI Thread Summary
China is planning to be the first nation to land a probe on the moon's far side, marking a significant milestone in its ambitious space program. The discussion highlights the challenges of communication with the far side, as existing deep space communication equipment may not effectively transmit data without a relay orbiter. Participants noted that interplanetary communication is typically reliable, but satellite-to-satellite communication on the far side could result in low data rates. The conversation also referenced Arthur C. Clarke's "2010: Odyssey Two," drawing parallels between fictional space exploration and real-world ambitions. The thread concludes with a humorous hope that China does not face any unexpected dangers during its lunar mission.

China aims to be first to land probe on moon's far side

China's increasingly ambitious space program plans to attempt the first-ever landing of a lunar probe on the moon's far side, a leading engineer said.

I wasn't aware that no one had landed a probe on the far side of the Moon before.

Are communications more difficult?

I assume so. I don't think any of our deep space communication equipment can talk with the far side of the Moon, but I'm not certain.
 
You need an orbiter around Moon. In principle probes at the Earth/Sun Lagrangian points or around the Earth/Moon L2 would work as well, but the larger distance means the data rate goes down, and I'm not aware of satellites there designed for such a task.

Interplanetary communication (e. g. with probes on Mars) works well with a huge antenna on Earth, but a satellite-to-satellite communication like that would give a negligible data rate.

China's increasingly ambitious space program

Did anyone read the book, 2010: Odyssey Two? By Arthur C. Clarke? I did. I actually claim that the movie adaptation with Roy Scheider (1984) is my favorite movie of all time (I always wanted to be Heywood Floyd with the hot Oceanographer wife and the dolphin pool inside my kitchen), with the movie "Pi" (1998) coming in a close second.

In any case, Arthur had the prescience to have a spot in the book (if my memory serves correct) where the Chinese beat us to the first landing on Europa, only to be greeted by creepy, black tentacles emerging through cracks in the ice to suck them down underneath that icy crust. Of course, their radio communications got abruptly interrupted. I don't know if Europa has an atmosphere, but I hear that in space, "no one can hear you scream." :H

Let's just hope that the Chinese don't encounter this same fate on the dark side of the moon...
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
