China Set To Launch First-Ever Spacecraft to the Far Side of the Moon, Will Attempt To Grow Plant There (scientificamerican.com)

AmiMoJo writes: Later this week, China plans to launch its Chang'e-4 spacecraft to the far side of the lunar surface. The aim is to land a rover on the dark side of the moon for the first time. Blocked from direct communication with the Earth, the lander and rover will depend on China's Queqiao communication satellite launched in May. If the landing is successful, the mission's main job will be to investigate this side of the lunar surface, which is peppered with many small craters. The lander will also conduct the first radio astronomy experiments from the far side of the Moon -- and the first investigations to see whether plants will grow in the low-gravity lunar environment.

The ultimate goal of the China National Space Administration (CNSA) is to create a Moon base for future human exploration there, although it has not announced when that might happen. Chang'e-4 will be the country's second craft to 'soft' land on the lunar surface, following Chang'e-3's touchdown in 2013.

      The "dark" side of the moon is the one that's tidally locked to point away from the earth. It gets the same amount of direct sunlight (although less total light, because it doesn't get reflected earth light.) It has more small craters because it gets hit more often (although the earth doesn't shield it that much) by meteorites.

      At the time, it was also speculated that it sank in something akin to quicksand. In case the same thing happened to the upcoming Viking mission, the Viking cameras were programmed to photograph a footpad and send it almost immediately after landing. That way, they'd at least get one photo, and verify the quicksand theory if the probe went dark.

      In the very first photo ever taken from the surface of Mars, the left side is kind of foggy. This is because dust was still in the air from the landing rockets. The cameras "scanned" in strips somewhat like a fax machine, so that as the scan "beam" moved right, the dust had settled.

    Any intention to spy on the far side of the moon by anyone other than the US space plane, which presumably has other missions to conduct, would involve building and launching a craft to do so at considerable expense.

    My argument is that any intention to spy on even the *NEAR* side of the moon would involve no less of an expense, and so putting a base on the far side would not pose any greater of a barrier than any other situated lunar base.

    It's not like you can spy on the moon from the ground or hell, even in earth orbit.

    I think you're highly underestimating technology, and it depends on the level of spying that is involved. It's much cheaper and easier to put a satellite in orbit around the earth than around the moon. With no atmosphere around the moon and a powerful lense from an earth orbiting satellite you could definitely see basic structures being built, maybe judge activity too and fro the building (which buildings are being docked with), you could monitor for electro magnetic signals. A lot of this could probably be done with existing satellites in orbit.

    Uh... citation?

    There's this little thing called google that was invented a few years ago... this isn't exactly secret knowledge (google or the spy plane) - how about you give it a try?

    I think you are overestimating optical acuity.

    The absolute *maximum* that we could resolve even from very high earth orbit is at best something that is no smaller than about 50 meters or so on the moon... and even then, it would be just a single pixel in size using even the most powerful telescopes that we have today. The only practical way to resolve any appreciable amount of detail that would be required to effectively do any spying on what is happening on the moon is at best from lunar orbit.

    And I think it's important to point out that this limit is not technological but physical. At a certain resolution you start running into Heisenberg's uncertainty principle which causes refraction to increase as you focus more precise.
