Honeysuckle becomes DSS-44 in the Deep Space Network





After the highly successful and complex Skylab missions, Honeysuckle was no longer needed for Manned Space Flight Support.

The decision was made to add Honeysuckle to the Deep Space Network as Deep Space Station number 44 (DSS-44). This involved a major refit of the station.

Mike Dinn recalls –

“A lot of the DSN equipment came from DSS41 – Woomera – Island Lagoon as it closed down.”

And John Saxon adds,

“Some of the other DSN equipment came from the DSN site at Hartebeesthoek in South Africa.”

Parabaloid Survey of the dish for the Deep Space era – August 1974.

Hamish Lindsay writes –

“In 1974 we adjusted every antenna plate to 5 – 10 thousandth of an inch to make a true parabola for maximum signal direction to the subreflector for the Deep Space era. The feedcone was removed and my theodolite was bolted to a special bracket (seen in the photo) to measure the four corners of each plate.”

After we left the Manned Space Flight Network the station was stripped completely bare of all the equipment and cables (except the antenna servo console seen looking lonely by the window).

In this picture of the USB area the underfloor cable and air conditioning plenum and 609.6mm square floor tiles can be seen under Stirling Finlay (USB) on the left and Charlie Collins (Comms), talking because there was nothing else to do.

conversion to DSN

This photo is taken looking the other way, with the Servo window behind the camera. The Receivers are on the left, and the old location of the Ops Desk is at the far end on the right.

Phil Maier writes,

“I found this photo of the mess at HSK/DSS-44 taken on 13 September 1974 during the conversion.

I think I see Les Hughes, Neville Eyre and Tony Salvage in the background. The soon to be DSN Ops desk is in the RH foreground.”

From time to time, Honeysuckle was called on to help with radioastronomy.

Hamish Lindsay writes –

“During the Deep Space era HSK used to fill in time helping Dick Manchester of the CSIRO to track the Vela Pulsar. To us this was very easy tracking because it was only a downlink so it was all within the USB section. PSR 0833-45, or Vela, was a pulsar in the Gum Nebula with a period of 89.3 milliseconds. The Gum Nebula is the remnant of a supernova that occured over 10,000 years ago with a diameter of 2,300 light years.”

and Radio Astronomer Dick Manchester writes –

“Timing the Vela pulsar is interesting because the period has unpredictable ‘glitches’ every few years, where the period suddenly decreases by about a part in a million. This is actually a huge change by the standards we measure pulsar periods to. The details of the glitch and its recovery give information on the interior of the neutron star.

The NASA stations were ideal for this as you need regular observations (at least weekly) with a stable system. It was difficult to get that at Parkes as it is scheduled in bigger blocks (with bigger gaps between pulsar sessions) and has different receivers at different times. (Actually, we can now change receivers quickly with a translator system, so that is not such a big problem.)”



letter of commendation

Shortly after Honeysuckle joined the Deep Space Network, this Letter of Commendation was received from Andre Caticchio at JPL.

“Mr D. Gray, Mr J. Saxon and the entire crew of DSS44 should be commended for their total professionalism in the tasks they performed.”
