The video section


This section is in the process of being compiled. Hopefully it will give some details – and photos of – the video section at Honeysuckle.


Early video configuration

Ed von Renouard (“Video Von”) is seated at the initial installation of the RCA scan converter before the slow scan rack was installed (note the camera in the top left corner of the rack). This probably would have been in 1967 or 68.

Compare it with the photo below, taken during Apollo 12 in November 1969.

Mincom M22 telemetry recorders

 

For Apollo 11, the slow scan television signal was modulated with the telemetry from the Lunar Module (including PLSS data).

A back-up recording of the Apollo 11 LM TV downlink was made in case there were problems with the RCA Slow Scan converter used at the stations. Instrumentation recorders were used – an Ampex FR1400 at Goldstone and Mincom M22s at Honeysuckle Creek and Parkes.

During the Apollo 11 EVA, the television was not only video recorded on the Ampex VR1100, but the slow scan video data was also recorded along with the rest of the telemetry from the Lunar Module. These – along with the videotapes – were shipped to Goddard and Houston after the mission (where most of them were reused!).

Ed von Renouard writes,

“for Apollo 11 we had the M22 telemetry recorders going at 120 ips (reel change every 1/4 hr for the duration of the mission) which also recorded the narrow-band slow scan TV downlink, and we had an ageing broadcast quality Ampex VR1100 4-head desk-size video recorder with 2-inch tapes to record the scan-converted NTSC-standard output TV fed to the US. This machine overheated during the downlink and kept on blowing fuses so we ended up opening its rear doors and positioning two desk fans to keep it cool. This worked and we were able record the rest of the TV.”

Ed von Renouard loads a tape on one of two Ampex VR 660C helical-scan video tape recorders, mounted above one another which were used instead of the VR 1100 after Apollo 14.

Photos of the video section during Apollo 17

Ed von Renouard writes:

“From Apollo 15 onward we had two Ampex VR660 helical-scan video recorders which are the ones you can see in the photo [on the left].

The scan converter had been retired and the downlink was now all-singing-and-dancing frame-sequential NTSC-standard colour TV as evinced by the RCA colour monitor on top of the rack (frame-sequential because of the RGB colour wheel in front of the vidicon camera used on the moon, the reference colour was green).”

The video that was on the monitor

And this is the scene that was on the monitor – Apollo 17, EVA 1, Jack Schmitt setting up the SEP (Surface Electrical Properties Experiment) at 123:07:30GET.

With thanks to Ian Regan for finding the video segment.

Nevil Eyre in video section

Another photo of Nevil Eyre at the video equipment during an Apollo Lunar EVA.

On the monitor – the Rover-mounted TV camera is looking down at the rover. One of the Astronauts is visible in the distance on the right.

Here are some other photos taken in and around the video area during Apollo 17.

video area Apollo 17

Nevil Eyre at the video racks, near the start of the first Apollo 17 EVA – at 122:25:48GET.

From left: Nevil Eyre, Bryan Sullivan (farthest from camera, leaning forward), John McLeod (next to Bryan) and Les Paal.

On the monitor, we see television from Geology station 1, near Steno crater.

See the screenshot below.

what was on the monitor

And this is the scene that was on the monitor – from the first Geology station, near Steno crater.

Part of the Rover and the high gain antenna is seen in the left of the picture. On the right Gene Cernan (front) and Jack Schmitt (behind – holding a rake) are about to sample soil.

After the 1st EVA

video area Apollo 17

From left: Nevil Eyre, Bill Perrin (standing), Evonne Vey ? (seated, back to camera) and Les Paal.

This must have been taken around 6.5 hours later – just after the first Apollo 17 EVA had finished (like the photo below). Nevil is perhaps logging videotapes, and the TV from the Moon has been replaced by a special test picture ;-) on the monitor at right.

Recorders, Apollo 17

Hard working recorder people John Vanderkly (on left) and Brian Hale during Apollo 17.

Note the Mincom M22 recorders on either side (and the hand-winder on the mission clock!).

This was taken not long after Apollo 17’s first EVA. 128:57:52GET, or 10:50:53pm AEDT at Honeysuckle on Tuesday December 12, 1972.

On the Moon, Gene Cernan and Jack Schmitt are settling down to sleep – and activities in the recorder section are also winding down (or should that be winding up?).

Hamish Lindsay adds that this timing puts the photo “towards the end of our pass (Tues 12 Dec, AOS 1232 : LOS 2312) with MAD already tracking, and the two spacecraft in a rest period, the LM astronauts having just completed their first EVA (Start 1054 End 1806 AEDT).”

(This photo – and some of the others in this section – might best go in the Apollo 17 section, when we get that together.)
