"Patching the PostgreSQL JDBC Driver" #Debezium users will love this: idle #Postgres replication slots no longer cause WAL pile-up in multi-database set-ups. Excellent contribution and write-up by @decmurphy_ of @ZalandoTech! engineering.zalando.com/posts/2023/11/…

This morning, @TrevorMahlmann took one of the coolest rocket launch photos I have ever seen! 🤯 Trevor put a lot of work into this photo, and I'm psyched to say Flight Club played a role in that preparation. Watch here to see how! Nice work, Trevor! 🚀🌞


Between legalising equal marriage in 2015 and abortion in 2018, this would be an epic progressive trifecta for the stereotypically religious and conservative Ireland It's a long way off - and in no way a sure thing - but it's exciting progress! rte.ie/news/analysis-…

Delighted to help out @Erdayastronaut with some numbers for this video! (It's also the reason why I made that Space Shuttle simulation during the week 😉) Give this a watch and support Tim's awesome work if you're not already! He's the king!

Can @RocketLab really catch a rocket with a helicopter?! I dive into their ambitious plans including the history of air recovery, other rockets that had parachutes & even talk about @SpaceX fairings! You're crazy for this one @Peter_J_Beck (But I ❤️ it) youtu.be/ZIaDWCK2Bmk

Starlink Hunters, this is all you need to know! 🛰️😍🛰️😊 If anybody would like a free trial of the Photographer's Toolkit on Flight Club to be able to input their precise location and lens/sensor details, DM me and I'll sort you out! You won't miss a single #Starlink pass again

My #Falcon9 S2 model is underpowered It was always likely, but after #Starlink it's obvious: 350m/s short over the course of the first S2 burn. @Erdayastronaut @elonmusk - is 348s @ 934kN too weak for the Block 5 Merlin Vac? What should it be?

Bi-annual shameless #Patreon bump! If you're a launch photographer, a programmer, or just a rocket launch enthusiast, you should definitely check out these Patreon rewards. Patrons also get tips+tricks from yours truly on how to best utilize the app 😉 patreon.com/flightclub

Playing with Instantaneous Impact Points. Can you spot the moving dot in the ocean? This is the first step in automating boostback, entry & landing burns by minimising the distance between this point and the landing site. No more manual trial+error with burn times and headings!

The difference between launching at the opening of the launch window (picture 1) vs launching at the "optimal time" (picture 2), 2 minutes later. Can you spot the difference? :) #Antares #Cygnus #NG11 @northropgrumman #ISS

Newest feature just deployed: save all of your favourite launch viewing locations for super quick launch planning! Simply click somewhere on the included map and it will auto-fill the coordinates for that location. No more Google Maps lookups required :)

Plotting the Indian anti-satellite test debris field in Flight Club's new dashboard. This new feature lets the user import up to 100 TLEs at once! Pretty explosive, if you ask me. 🚀🛰️💥💫

Check out this absolute [Falcon] cracker from @Mike_Seeley - Michael used Flight Club to help frame this up! I'm super psyched with how close this prediction was, considering how little info I had on #FalconHeavy, the flight profile, booster throttling, etc, etc Bring on STP-2!

Boys and girls, new profile is up! We got all the usual hints and we got a few extra ones for good measure - I've got a lot of confidence in this, considering it's the first ever launch of a super-complex profile with 3 booster-landings Check it out here: www2.flightclub.io/result?code=AS…

Know any launch photographers that you think might benefit from Flight Club's photographer toolkit? Send them this way, and they get one launch on the house! What better way to test the app than with the monstrous #FalconHeavy and it's 4 simultaneous trajectories?!

Declan Murphy Reposted

New trajectory visualisation UI is gonna be rolling out after Falcon Heavy launches. Here's a video where I go through the features of the UI specifically designed for photographers, but there will be tonnes of features in there for everyone else too :) youtu.be/uxoIqg3ImBk


Declan Murphy Reposted

I don't have any Falcon Heavy news, but ehhh.... Can I offer you some brand new features on Flight Club instead?


Declan Murphy Reposted

Ok, we solved the droneship location mystery! Next: what's the target orbit for @Arabsat 6A, as far as the @SpaceX upper stage is concerned? Highly elliptic, but supersync GTO? Or is the upper stage gonna do some sort of GEO insertion after a long coast? #spacex #falconheavy
