Will try to write more and sidestep the depression a bit, but until then… this quickie post will have to do. It presents WATT friend and reader (!) LunaCognita’s latest film, an unprecedented proper look at the footage of the lift off of the Lunar Module from the end of the Apollo 11 mission. He pretty much explains what’s what with it below, but, do note that near to and again at the end of this clip there are two unidentified objects seen landing

and they both land…

in the very same spot!

WAAAH!

LunaCognita | December 31, 2010

This presentation shows the 16mm Data Acquisition Camera (DAC) footage that was shot during the Apollo 11 ascent from Tranquility Base. In this ascent footage, the DAC motion picture camera was mounted in the right side forward-facing (LMP) window of the Apollo 11 Lunar Module “Eagle”, providing us a view looking down at the Moon’s surface as the LM ascent stage fires and sends the spacecraft on its way back up to lunar orbit for rendezvous and docking with the CSM “Columbia”.

Rather than just showing the raw footage here as it is cataloged in the NASA film archives, I instead show the footage in a rotation-corrected format in order to always keep the scene in it’s proper “horizon up” viewing orientation throughout the duration of the clip. This proper “horizon up” perspective can be established based on some simple visual criteria, with the goal being to ensure we are viewing the footage with the lunar surface being shown so that the Moon’s horizon that is closest to the camera’s current principle point always remains aligned and level towards the top of the field-of-view (even if the horizon itself is not actually visible at the time). This ensures that the surface scene you are viewing can be accurately interpreted.

As you can see in this footage, the rotation correction to align the scene to the “horizon up” viewing perspective is an absolutely vital adjustment that must be applied first in order to be able to even begin attempting to analyze and interpret scenes such as this one accurately. Because the DAC camera was hard-mounted in the window of the LM during liftoff from the lunar surface, this meant that the standard locked display perspective that NASA provides in their archive clips showing the Apollo ascent footage is ALWAYS displaying the lunar surface scene below in an inaccurate perspective. For over 40 years, the public has actually been watching ascent footage like this from the various Apollo missions where the lunar surface after liftoff is being shown essentially upside down (between 135 to 180 degrees off of the “horizon up” viewing perspective).

The point to this simple presentation is to merely serve as a reminder to everyone who is interested in doing their own analysis of ANY of the Apollo DAC footage or still frames of the lunar surface to always consider the question of “what is the proper viewing perspective for each scene?” The ugly fact is that the vast majority of the Apollo DAC footage and still frames, as they are archived by NASA, are not presenting their lunar surface scenes to you in anything close to the proper “horizon up” viewing orientation that our eyes expect to see. Obviously, unless this improper viewing perspective is corrected for first, you have very little chance of being able to analyze the scenes you are looking at with any degree of accuracy at all.

In addition to the rotation-correction, I also was forced to make several frame-rate adjustments to this Apollo 11 DAC footage, and the reason for that is because just before the four-minute mark after liftoff, the 16mm DAC camera suddenly alters it frame exposure rate, switching from 12 frames-per-second (the proper declared setting for filming the liftoff and ascent) down to 6 fps. I have no idea how or why this sudden frame-rate setting change occurs, because adjusting the DAC camera’s fps setting “on the fly” was certainly not one of LMP Buzz Aldrin’s checklisted duties during ascent, and I see no mention in the Apollo 11 mission and post-mission reports to account for this anomalous occurrence. The Apollo 11 ascent footage, as it is archived by NASA, makes no attempt to correct for (or even draw attention to) this sudden step-down in frame-rate, which results in the raw archive footage appearing to suddenly show a doubling of the playback speed. In addition to this, NASA typically renders their HD digital DAC archive at 29.97 NSTC, resulting in further interpolation stretching being introduced in the digital footage. I have attempted to correct for this effect here in order to ensure that the playback rate of the DAC footage accurately matches the accurate timeframe that I was able to establish using the accompanying raw mission audio track and flown liftoff&ascent charts – essentially using the accurate audio timeline to re-synchronize the inaccurate video playback rate so they match up correctly for the duration of the nearly 10-minute complete sequence of footage showing the Apollo 11 ascent from Tranquility Base.

If you’d like to check it out, there is a nice discussion of this work going on over at ATS. Short so far and very well reasoned.
