@geoffc pings to users who haven't been in chat for a while go silently unreceived and fall off the edge of the Earth. Now, about these cookies, I guess you guys ate them all because I can't find any!

Q: Eleven community wiki answers to a question?

The "oldie but goodie" question What are the choices today for orbital mechanics simulation software? has eleven separate community wiki answers (more if you count the deleted ones). Would the ideal situation be a consolidation of at least all of the short answers into one CW but perhaps leave t...

@uhoh I was not sure. I saw that our conversation was moved to chat, would he see them now if I pinged him?

Guru Vishnu

I think pings wouldn't work when someone hasn't visited chat for 48 hrs or so. You may try to invite that particular user from their user profile.

@geoffc it was not moved to just any chat, it was moved to this chat

@GuruVishnu I think it's longer than that and may depend on how you ping them, by typing or by replying to a specific entry they'd made here earlier.

but how exactly does one "try to invite (a) user from their user profile"?

Starlink launch 5 (6th set of 60) is in 5 min. They just did a job ad for Boca Chica on the webcast. Funny.

5th flight of the booster.

Reflying the fairings. Only second stage is new. Getting closer to full reuse... (Second stage never will on F9 but such a huge improvement over everyone else so yay!)

Guru Vishnu

geoffc

Cool. Did not know that. Thanks.

T-30 seconds

So it chat profile, not regular user profile... How do you get to that for someone never usinig chat before?

Liftoff.

I cannot wait for Starship to start test flights. SN3 hopefully (under construction) for hops.

3 Raptors will be awesome. Interestingly, about as much thrust as an F9 launch, and almost no launch pad infrastructure. Which should be sporty!

And launched, orbit, no word on stage landing.

Guru Vishnu

@geoffc Then I think asking them to join the chatroom through a comment below their post is the only way.

geoffc

Ah well. Perhaps he will follow up iin the custom chat room for that message. I think he has good and bad points. Would be fun to discuss.

Guru Vishnu

Were you referring to mothman?

If yes this is their chat profile. Inviting them is a few clicks away:

@GuruVishnu Done, thank you. I was hoping I could add a message, alas was not to be.

Interesting. Early engine shutdown on launch. Good to have 9, made orbit no issues, looks like it failed to land, but waiiting for more news on landing.

Open source software is becoming more and more popular. Here’s how you can create a plan to ensure that your open source implementation is secure as well as effective.

@GuruVishnu cool, thanks!!!

@geoffc how early is early?

Guru Vishnu

You're welcome geoffic and uhoh :)

JCRM

that's a shame. finding out what went wrong with the engine would have been helpful

Guru Vishnu

@geoffc Was that the first stage or the second?

JCRM

the second stage only has one engine (unless they've iterated)

geoffc

15:10

@uhoh Current theory is based on video evidence showing a flash, a few seconds before MECO. So pretty much at the very end, so late early. :)

@GuruVishnu First stage has 9 engines, and lost one. Second stage has one engine and if you lose it, game over, so can't be second stage.
