Will an alien have sneaked on board? That would be a great prank from the ISS crew.

I'd have made a facehugger and stuck it to the dummy's head.

I genuinely thought that Falcon Heavy was never going to fly again.
Careful, Kim. Your sarcasm's showing...

Having already booked a payload for the re-flight of the boosters is impressive optimism   :o

Arguably the Falcon Heavy is an exercise in messing about.  That's why I didn't think they were going to pursue it further than the demonstrator, in order to concentrate on whatever BFR's called this five minutes.  (Note successful first - tethered - test of the Starhopper last week.)  Presumably there's good money in flying bigger payloads.

An interesting take on Falcon Heavy here from "Curious Elephant" on Youtube.

https://www.youtube.com/watch?v=HsuidLeU7yY

He thinks its too powerful for the loads available given that today's lift off could have been done by a normal Block 5 Falcon 9.

Just disappointed that according to Spaceflight Now, the window is well after Midnight tonight so I am likely to be asleep.  :(

Goes off to watch it now....wasn't allowed to yesterday as had DIY stuff to do.

Fly safe!

Watching a Space X landing of any sort is just so surreal to this person brought up on Thunderbirds and the like.

Indeed.

After yesterday's scheduled launch was scrubbed due to high altitude winds, everything's gone to plan so far today.

All three boosters safely recovered, second stage burn looking solid...

That must've been noisy, between the bottom of the spacecraft, and where the spark reinstates its path to earth.

It's a callback to Apollo 12 being struck by lightning shortly after lift-off, knocking out various systems including the telemetry.

"Try SCE to AUX" was the advice given by one of the flight controllers, who'd remembered the telemetry failure pattern from an earlier test when a power supply malfunctioned in the CSM signal conditioning electronics (SCE).

Thanks, I'm up to speed with the sayings of steel eyed missile men.

My "Heh" was (very), shorthand for "Ooh, I can caption that with 'Try SCE to AUX' if I haven't been beaten to it. Oh I have, and quelle surprise it was Kim wot posted it."  Of course you would have grasped the nuance of my posting if I hadn't included a rogue question mark.

Jump starting a Lunar Module.

That reads like a lost chapter from the second half of The Martian, discarded because the Lucky Cable had seen enough action already.  But if I'm getting my acronyms right, they're just using the rover as a ladder in order to access the relevant part of the ascent stage so they can hot-wire the pyrotechnic subsystem and fire the engine.  (Presumably in case of a relay or wiring failure.)

ETA: Actually, re-reading it, they're not firing the engine, they're firing the pyrotechnics that separate the ascent stage from the descent stage.  Presumably they fire the engine after the hatch is safely closed.
Careful, Kim. Your sarcasm's showing...

Jump starting a Lunar Module.

I have taken note of all of these points and am going to re-claim my heavy duty jump leads (think jump-starting artics) from work, where I donated them, thinking I would have no further use for them.

ETA - I love this:
Also worth noting that launch happens with the hatch open, and with the cables dangling out of the door until the crew unhooks them and tosses them out the hatch.

Indeed.  I'm failing to find a reference to the "ED adaptor cable", but it sounds like it was specifically designed for this purpose.  The GSE connector will have been used to provide power to the systems prior to launch.

ETA: Or not (see edit to previous post).

I don't know for certain with NASA terminology, but generally we say EGSE for Electronic Ground Support Equipment.  The only other GSE I'm aware of, are the MGSEs, Mechanical Ground Support Equipment, as infamously not used correctly, when someone dropped NOAA-19 (the big white bit is  MGSE).

Actually, it is rocket science.
