Starlink 10-9 launch bulletin (Falcon 9 return to flight)
Falcon 9 returns to flight after the upper stage failure on Starlink 9-3. The cause was found to be a crack in a sense line for a pressure sensor attached to the vehicle’s oxygen system.
Starlink Group 10-9 launch out of LC-39A in Florida currently scheduled for 2024-07-27 04:21 UTC, or 2024-07-27 00:21 local time (EDT). Booster 1069-17 to land on Just Read the Instructions.

Is she... reading a sheet of aluminium foil?
Yay! I've been experiencing some "launch withdrawal" symptoms :)
That’s 27 hours from now.
I suppose I'd better get a launch thread up soon!
Interesting failure and fix:
the liquid oxygen leak on the upper stage led to the excessive cooling of engine components, most importantly those associated with delivery of ignition fluid to the engine. As a result, the engine experienced a hard start rather than a controlled burn, which damaged the engine hardware and caused the upper stage to subsequently lose attitude control.
For near term Falcon launches, the failed sense line and sensor on the second stage engine will be removed. The sensor is not used by the flight safety system and can be covered by alternate sensors already present on the engine.
Seems like another case of Elon's favourite, "try very hard to delete the part or process".

Thanks for sharing. I had not seen that.
The Edmund Fitzgerald has entered the chat.
Wow, that's quite the ordeal. He blew across nearly the entire Pacific!
Is that what frogs say in Finnish? I always find it interesting what onomatopoeia different languages use for animal sounds...
Godwin's Law.
Perhaps, but I feel like a second level comment was too early to invoke it. Also, there's also the common corollary that whoever invokes Goodwin's law definitionally loses the debate...
Username checks out.
How about more veggies and legumes?
If I were homeless, I'd take beans over Coca Cola any day...
I presume they had to tare the bear in order to weigh the baby.
We're on track to have the smartest, healthiest, elderly mice this century! Here's to hoping some of these treatments are applicable to humans as well.
Electric cars are only viable if people can use them on the same infastructure, in roughly the same way as gasoline cars.
Eh, I think there is should be a difference in behaviour between ICE refueling and EV charging.
The only people who should be charging their vehicles "roughly the same way as gasoline cars" are those who can't charge where they park. If you own a driveway or a garage, you should install a charger there, charge overnight while you sleep, and leave with a "full tank" every morning.
It doesnt need to be "gas stations" anymore, but they need to be as convenient, at least in their own way.
Definitely this. We don't need as many charging stations as we did gas stations, and "home" should be the most convenient place to charge.
delaying its robotaxi reveal, explaining it was because he requested an “important design change to the front.”
This front better be good. I hope it's a functional change, like camera placement or something, rather than cosmetic.
Are you sure about that?
Thanks for the recommendation! I'll add it to my list of places to visit in Ottawa.
Yes, but it would still be easier if people in similar areas agreed on whether to follow it or not. Having nesting-doll sections of the map which do/don't follow DST is insanity.
I don't think I've ever seen "percent" abbreviated as "pct" instead of "%" before...

Making liquid nitrogen is quite an achievement, especially using salvaged air conditioner and refrigerator parts. A nice application of the Joule-Thomson effect and countercurrent exchange too.

> Teams completed ground hot fire testing at White Sands and are working to evaluate the test data and inspect the test engine. The ongoing ground analysis is expected to continue throughout the week. Working with a reaction control system thruster built for a future Starliner spacecraft, ground teams fired the engine through similar inflight conditions the spacecraft experienced on the way to the space station. The ground tests also included stress-case firings, and replicated conditions Starliner’s thrusters will experience from undocking to deorbit burn, where the thrusters will fire to slow Starliner’s speed to bring it out of orbit for landing in the southwestern United States.
> Integrated ground teams also are preparing for an in-depth Agency Flight Test Readiness Review, which will evaluate data related to the spacecraft’s propulsion system performance before its return to Earth. The date of the agency review has not yet been solidified.
WYR: Legs as long as your fingers, or fingers as long as your legs?
I'm honestly not sure which I would choose. Both sound incredibly inconvenient.

144 launches in 2024 is now looking unlikely, given the ongoing investigation into Falcon 9 the upper stage failure on the Starlink 9-3 mission.
Differences between template styles?
Source, One-to-one, One-to-one (keep incorrect)
I can't notice any differences between these. How are they different?
Dotted Small, Dotted Big
These seem similar, but I'm still not entirely sure how to use them.
They seem to overlay the intended pixel colour in the center, and display the current colour of the pixel a couple shades lighter. Is this correct?
What advantage is conferred by altering the current colour of the pixel?
Possible bug: If the intended pixel colour is white, but the current pixel colour is grey, this is lightened to white when the template is applied. There is no way to tell that the pixel is the wrong colour while the template is on.
Is this a bug, or am I not using them correctly?
Thanks!
Edit: After the server maintenance on July 13th, it seems the bug has been fixed.

Starship Development Thread #57
Portions of this thread copied from a Starship Dev thread on r/SpaceX.
FAQ
- When next launch? (IFT-5) Booster catch NET Aug 2, per Elon.
- When previous launch? (IFT-4)? Booster 11 and Ship 29 launched on 2024-06-06.
- What was the result? Both booster and ship make it to landing burn and splashdown. Ship flaps took a beating on reentry, but remained in control of the vehicle.

"Tradition"
I'm pleased that Daily Hopper has been a bit more active recently. Their comics are quite good.
"And we have a successful landing of the Ariane 6 core stage on the drone ship!"
I wish. Maybe one day?
Canvas 2024 is in 2 days. Can the HI community do better than last year?

The [email protected] event begins in 2 days! Any Tims interested in placing some pixels in the 2024 Fediverse Canvas?
A bit of history if you are curious...
r/place 2017
This was the original r/place event, and the only one that Grey and Brady discussed on the podcast.
Grey and Brady faces, Numberphile "pi" logo, Flaggy Flag, HI logo, Nail and Gear, CGP Grey flask icon, "r/hellointernet", White Cross, and "Tims!"
r/place 2022
- Left panel: Audrey, allied territory, and bees.
- Middle panel: Grey and Brady faces, HI logo, Nail and Gear, and "CXXXVII" (137 in roman numerals)
- Right panel: CGP Grey the lady penguin, allied territory, Numberphile "pi" logo, CGP Grey logo, allied watermelon, plane crash corner, and a tiny 4x4 Professor Poliakoff.
r/place 2023
Last year, we were unable to secure a single large territory, but managed to claim and hold multiple small territories.
Region 1
CGP Grey bot, Nail and Gear, split Grey and Brady face, HI logo, 137, and Flaggy Flag. Unfortunately, this region was steamrollered by a streamer and did not survive to the end of the event.
Region 2
CGP Grey bot, plane crash corner, Flaggy Flag, HI logo, and Audrey.
Region 3
Another HI logo, 137, and bees.
Region 4
Near the very end of the event, we managed to secure a whopping 24x24 region on the "taskbar" at the bottom of the canvas. We had to fight off a barbie to get it (true story), but the Tims held strong!
Fediverse Canvas 2023
And finally, our humble patch on [email protected] last year.
Fediverse Canvas 2024
The [email protected] event begins in 2 days! Would this community be up for placing some pixels?
There are already a few Tims organizing in the "Tim Army" Discord but I thought it would be nice to have some people from here as well.
What do the Tims say?
