content: How did the world get to see the video of Neil Armstong taking his first steps on the moon 50 years ago today?Come on a tour of the Honeysuckle Creek tracking dish and site that received those historic first images.

content: I had the chance to visit Honeysuckle Creek before it was demolished. They essentially had just turned out the lights, locked the door, and went home. Everything was left in place as it was - equipment, office furniture, noticeboards, everything.Unfortunately over the years, vandals trashed it. The place also had lots of contamination from asbestos, PCB, and other nasties. In the 90's it was completely demolished, and left as an empty paddock for many years.Nearby Orroral Valley Tracking Station met the same fate.

content: So they didn't even try to sell off the gear, commission it to get scrapped,or turn these places into tourist attractions or caravan parks?I'll bet taxpayer/battlers aren't impressedWho owns that land anyway, and if it's NLR, why not handball it back to indigenous localsthey ripped it off from in the first place anyway?That's not 'rocket science' to figure out and door is it ?

Who cam blame him.

content: Quote from: Electro Detective on July 22, 2019, 09:15:04 amSpeed, fuel economy, reduced emissions, that's pretty much one of those "pick any two" situations.It depresses me that the Concorde was retired with no replacement but it was very expensive to operate, having a small passenger capacity and an incredible thirst for fuel. It was transportation for the elite super wealthy, not something for the masses. Sure was a technological marvel though.

content: Quote from: joseph nicholas on July 20, 2019, 10:41:19 pmAnd whether he paused or for how long, maybe when he said the word something along the way from the microphone to the transmitter to the propagation conditions to the receiver didn't enable the full signal to get from one end to the other. To criticize Neil Armstrong over any version of this seems kind of (very) strange.

content: And not to go all techie, but since this is EEVblog, I'm wondering if he had a Push to Talk Mic, or VOX. Either way, but especially with VOX (or even PTT when you are doing something else other than rag chewing), anyone who has ever operated an amateur (or professional) radio will know that the potential for missing a syllable or a word is pretty high especially if propagation conditions are at all challenging. And on top of the communications system and propagation conditions I think it's like Dave said - he had some important and risky work to do.

content: I'm not criticizing Neil in this, I'm supporting the idea that he always intended for the 'a' to be in there!Sure, there's many reasons the pause could be there but I think it's a darn plausible one that with all that's going on, he knew he missed the 'a'. Like right before doing anything important, thinking "don't mess this up...don't mess this up" and what happens? You mess it up.I'm not saying he was some kind of idiot for messing up what he planned to say. Not under that kind of pressure. Sheesh. Yes, there were countless things distracting him from forming a sentence that is not merely a once in the lifespan of an entire species event.

content: I worked at the Winkfield (UK) NASA Stadan station. Most of the equipment was NASA owned. If any equipment became redundant it had to be either destroyed or sent back to NASA.This I believe was because of UK Customs. Of course it was cheaper to destroy the items.

content: Thank you for a very enjoyable video, presented with your usual contagious enthusiasm, so much I didn't know!I vaguely recall watching it, as a kid... my father called me to the living room, way past bed time, saying "Come and watch world history in the making"...I hope we (mankind) eventually regain our mojo with respect to space exploration... seems like we are waiting forever to take the next step, after the first small one.
