When Kim Il-Jong recently visited Moscow on a surreal train journey, he proudly informed Vladimir Putin he was travelling in the armoured train given to his father as a present by Stalin.
By Phil Plait August 12, Over the course of three more years, we did it five more times.
Despite the return of hundreds of kilos of rocks, thousands of pictures, and independent verification and authentication from dozens of countries some of which were and still are our enemiessome people stubbornly refuse to accept the fact that the Apollo Moon landings were real.
The basic idea is that when the astronauts left the Moon, they left behind several artifacts, including the base of the lunar module called the descent stage and the rovers for Apollo 15, 16, and The descent stages were a little over 4 meters wide the landing legs spread out were 9 meters across, but are narrow, so the bulk of the stage would be easier to see.
The rovers were about 3 meters long and 2 wide. Those numbers sound like you should be able to spot them with, say, Hubble. The question here is one of resolution: As an example, a person standing next to you is easy to see and easily identifiable.
But from a mile away that human is far more difficult to see, and from ten miles away is just a dot if that. There is a simple relationship between mirror size and resolving power: What does this mean? An arcsecond is a measure of angular size how big an object appears to be — if two objects are the same physical size, the one farther away will appear smaller, and have a smaller angular size.
There are arcseconds to a degree, and to give you an idea of how small a measure this is, the Moon is about 0. D is the diameter of the mirror in centimeters. So what does this mean if you want to look at the lunar artifacts? Hey, wait a sec! It would have to be a lot bigger to be seen at all.
In other words, even a football stadium on the Moon would look like a dot to Hubble. But those objects are far, far larger than the Moon.
So even if we built a colossal sports arena in Tycho crater, Hubble would barely see it at all. The landers, rovers, and other junk left on the lunar surface by the astronauts are totally invisible.
However, there are two tricks we can use here. One is to look not for the artifacts themselves, but for their shadows. At sunrise or sunset, the shadow from a lander might be long enough to detect, even if the lander itself is invisible.The Daily Kos Elections Morning Digest is compiled by David Nir, Jeff Singer, Stephen Wolf, and Carolyn Fiddler, with additional contributions from David Jarman, Steve Singiser, Daniel Donner, Jame.
