To be fair it was probably much easier to connect with the paths of the Sun and Moon (and the phase of the latter) before we messed the climate up to the point that we now get six months of permacloud.

I have this vision of SN9 weaving its way out to the launchpad, rocking from side to side, going "I really love you, Elon. You're my best mate. Hic!"

SpaceX are now saying:
"SpaceX is standing down from Friday’s launch attempt of the SXM-7 mission to perform additional ground system checkouts; teams are working toward no earlier than Sunday, December 13 for the next launch attempt of SXM-7."

It's not the easiest interface to a camera to use, is it?
I've just attempted to add support for Basler cameras using Pylon into oacapture and it's been a bit fraught as I worked through issues like being told the gain control wasn't available only to find out later that it was (because by that time I'd turned off auto gain). I possibly also made things worse by switching between the Pylon interface and the Genicam one where it was easier to use one than the other. Still, done now...

Just got home and I haven't missed it
Indeed not. I think the suggestion was that if they're going to have another go tomorrow it will be around the same time.
James

Yup. Game over for today. Shame
Perhaps they'll have another crack at it tomorrow.

Scrubbed
Completely? I'm seeing a reset to T-15 at the moment.

Somehow I'd missed the fact that they have a drone ship for landing the first stage called "Just read the instructions"

Prerequisites
Physics and Maths (1st year of bachelor):
- Trigonometry
- Derivatives and Taylor expansions
- Integral calculus
- 1st order differential equations
Trig I can handle, probably derivatives, calculus and differential equations too. I'll have to look up Taylor series stuff though. I know I did that at school more than thirty-five years ago, but I can recall nothing about it now. I have a vague idea that it's about approximation using infinite sums of values in a geometric progression, but I could be completely wrong there.
Looks like an interesting course though. Do you know if the course runs in rotation if I don't have time to start it right now, or is it a one-off?

We have another delay on the SXM-7 launch. Now 17:55-ish GMT I think.

Looks like SpaceX's SN9 had a rough night:

Scheduled to launch at16.21 GMT, unfortunately I shall be out then and miss it.
Dave
That's what I thought, but SpaceX don't have their coverage starting until 17:20 GMT now. It looks like there has been an hour's delay.

Thanks, Stuart. I'll check out what's going on with the QHY5. It should work (and certainly used to), so perhaps I've broken something.

There's some more information in the README file here by the looks of it:
https://github.com/nekitmm/starnet
Otherwise I can't try much at the moment as our son is burning most of our internet bandwidth streaming his school lessons

Eastern time is five hours behind GMT? So that means the Falcon 9 launch is scheduled for about 4:30pm tomorrow afternoon for us?

I still find it incredible that you can watch this stuff happening live from the other side of the Atlantic.
Absolutely. Also amazing about the NSF streams over the last couple of days was that they have remote controlled cameras filming the launch that are basically consumer camera bodies with some modifications, run by people thousands of miles away, and the whole stream is put together by someone else thousands of miles away. And it all works

I'm almost certainly going to need some help to test support for these cameras in oacapture on Linux. If anyone fancies trying it when I'm ready, please do let me know.

Some interesting discussion at the moment on the NSF channel about the fact that SpaceX want to launch from the same site tomorrow, but if NROL-44 doesn't fly tonight they may try to bump SpaceX. Not everyone is apparently happy about this situation
James
-
Apparently they have some alarms, so it may not happen for that reason.
James

No cloud according to my commentary.

The ULA heavy launch appears to be streamed here:
though the stream doesn't seem to have started yet.

I had this in mind, scary that GA got it almost spot on..
Especially when you see the Starship mock-ups that have windows in.

Yikes, wooden scopes are so wrong
You do need to do an awful lot of polishing to make a good mirror, it's true. It's still a lot easier than making a wooden refractor though.
