The moon is 6783 miles 'round at its equator
18.84 miles per degree of arc
0.314 miles per minute of arc
27.6 feet per seconds of arc
The Apollo 11 mission Report says that when the eagle touched down, the MSFN system tracked the bird to 0.631 north and 23.47 east. Tranquility Base
was determined to be at 0.6875 north and 23.433 east. This determination was said to have been officially made 08/01/1969 (the time of the first
successful LRRR targeting).
What is the distance between the MSFN real time solution and Tranquility Base actual/official ?
You'll note reading footnote (a) of the Apollo 11 Mission Report table 5-IV, a correction had to be made going from trajectory derived
coordinates(this includes the MSFN numbers) to map based numbers (the official Tranquility Base figures fall into this latter category). Per the
Apollo 11 Mission Report table 5-IV footnote (a) those correction factors are ADD 2' 25"(0.04 degrees) TO THE NORTH COORDINATE, SUBTRACT 4' 17"(0.07
degrees) FROM THE EAST FIGURE.
There you go DenyObfuscation, you have all you need now to find the distance between the two points on a map of the moon(the MSFN real time solution
for the Eagle's landing site is one point and the ultimately official LRRR targeting certified Tranquility Base site is the other point)
MSFN based landing site solution numbers are 0.661 north and 23.40 east, here now having taken the correction factors into account. One simply
takes the difference of the north figures and squares. Take the east figures and subtract one from the other and square. Add those two figures and
take its square root. A very simple pythagorean solution to determining the distance between the two points.
With respect to the north coordinate (0.0265)(0.0265) + and east (.033)(.033) = 0.0007 + 0.001089= 0.001789. The square root of that is 0.0425.
0.0425 is the "distance" in degrees separating the MSFN real time solution and Tranquility Base's location as was ultimately determined by careful
study (photos, flight data and LRRR targeting). As there are 18.84 miles per degree, the MSFN and Tranquility Base coordinates are 0.0425 X 18.84 =
0.8 miles apart.
In the other thread I got 0.72 miles so I suspect the difference in the answers has to do with my rounding differently in the 2 cases.
You should check my work regardless DenyObfuscation.
We see Apollo proven fraudulent here as Eagle launch FIDO H. David Reed was told that the MSFN solution was at least 4.7 miles from what Tranquility
Base's location turned out to be. This from Reed's nice chapter in the book FROM THE TRENCH OF MISSION CONTROL TO THE CRATERS OF THE MOON;
"After Apollo XI landed, as the World celebrated and sipped champagne, I slept in preparation for my shift prior to lunar launch. I wouldwork with
SELECT and DYNAMICS to get all the relative geometry down and work out the correct ignition time for return to the CSM.Piece of cake really. All we
needed were landing site coordinates and a solid ephemeris on the CSM. I sat down at the console for that prelaunch shift and was debriefed bythe
previous team to complete hand-off. I probably had my secondcup of coffee by then and got on the loop to SELECT to get the bestlanding site. I
remember asking SELECT what he had for landing sitecoordinates. I’ll never forget his answer when he said, “take your pick FIDO!” I also
remember not reacting too positively to his offer. He explained that we had five different sites. He said “we have MSFN(tracking radars), PNGS
(primary LM guidance computer), AGS(backup LM guidance computer), the targeted landing site and, ohyes, the geologist have determined yet another site
based upon thecrew’s description of the landscape and correlating that with orbiter photos”. No two of these were even close to each other.
I remember taking my headset off and walking up to the Flight Direc- tor, Milt Windler to explain the situation. We only used that kind of face to
face communication when we had a serious problem such as this.....
Now we had the data we needed to run the problem (a rendezvous problem in reverse) and get the correct liftoff time*. And that’s what we used. Later
we would find out just where were we on the surface. We were actually over 25,000 feet from the nearest of the other five choices we had! At 5,000-fps
orbital velocity of the CSM that could have been up to a ten second error in liftoff. That would have meant we’d need a LOT of RCS (reaction control
system fuel) to play catch up or slow down in a rather abnormal (I don’t recall train- ing for this one) rendezvous situation. "
Everyone interested in Apollo should read H. David Reed's book chapter, read the relevant Apollo 11 Mission Report sections as well. Do the
calculations on your own. Write to Obama.
How sickeningly and unbelievable FAKE!!!
