Je ne veux plus fréquenter les gens qui disent « À quoi ça sert ? ».
J’ai 50 piges sur mon passeport, 12 ans dans ma tête (et 18 ans dans mon slip, dirait ma femme).
Et je compte bien que ça dure.
Je ne supporte plus les pisse-vinaigre professionnels du scepticisme.
À quoi ça servait de vouloir voler ? De traverser les océans ? De marcher sur la Lune ?
À rien. Jusqu’au jour où quelqu’un l’a fait.
J’ai toujours eu une tendresse infinie pour les originaux. Les inadaptés. Les rebelles. Les emmerdeurs. Ceux qui ne rentrent pas dans les cases.
Ceux qui ont des idées absurdes, des ambitions démesurées, des projets improbables.
Parce que ce sont eux qui font avancer le monde.
Pas les gestionnaires du déclin.
Les gens suffisamment fous pour croire qu’ils peuvent changer le monde sont précisément ceux qui finissent par le changer.
Et ce qui me terrifie aujourd’hui c’est l’état d’esprit que nous transmettons à nos enfants.
On les élève dans une atmosphère de fin du monde permanente. Entre malthusianisme, injonctions à la décroissance, culpabilité écologique et anxiété organisée.
Quelle terrible inversion des valeurs !
L’écologie devrait être un formidable défi lancé à l’intelligence humaine, pas une pédagogie de la résignation.
Je ne veux pas d’une génération qui s’excuse d’exister au point de ne plus faire d’enfants
Je veux une génération qui brûle d’envie de découvrir, de créer, de baiser, de comprendre !
l’optimisme n’est pas de la naïveté mais le courage de croire en notre capacité à tout affronter.
Le progrès n’est pas une fatalité mais une conquête.
C’est mon ode aux rêveurs, aux inventeurs, aux enthousiastes, aux insoumis, aux doux dingues et aux emmerdeurs magnifiques.
À tous ceux qui disent « t’es cap ? » plutôt que « À quoi ça sert ? ».
J’ai 50 ans, et je refuse de devenir vieux dans ma tête.
Aux fous qui veulent changer le monde !

No update needed. Now, about transponders for the rockets...
Thanks to @elonmusk, now @flightradar24 is gonna have to update its software to track Tesla Roadsters too. 😀

Replying to @flippers79 @Tesla
Something so cool people will try and cope by saying it's not practical.

Post-flight analysis confirms the Artemis II Orion heat shield performed as expected during its Mach 39 reentry, protecting the spacecraft and the astronauts aboard as they returned from the 694,481-mile journey around the Moon. go.nasa.gov/4B7EWNT

NASA and L3Harris engineering teams at NASA's Stennis Space Center scrubbed today's RS-25 engine test before the scheduled hot fire began. Teams are securing the test article and facility to prepare for a rescheduled test. Check back here or follow @NASAStennis on Facebook as we will provide additional information when available.

🚀 The time is now! 🚀
After countless hours of work, planning, and refining, Starship Tracking is excited to finally unveil the brand-new website!
🔗 Explore the new website here: Starship-Tracking.com
Designed to bring the action covered by Starship Tracking all that much closer to you.
From the launch sites to the vehicles themselves, the goal has always been the same: make it easier to follow the incredible things happening with Starship.
Thank you to everyone who has followed along, supported our journey, and helped make this possible. There’s so much more to come.
The future is being built with Starship.
Welcome to the new Starship Tracking Website.

The first Starship to return to its launch site, Ship 40's journey took it across air, space, and sea. Now that it is vertical alongside three other Starships in a Megabay at Starbase, it will provide first-of-its-kind data on a flown Starship heatshield, Raptor engines, avionics, and more.

Checking in with two deep space explorers. 🚀🛰️
Our Psyche mission to a metal-rich asteroid launched 3 years ago today, and tomorrow marks 2 years since Europa Clipper set sail for Jupiter's ocean moon Europa.
(The same rocket side boosters were used for both launches!) 1/3

NASA is targeting Wednesday, Oct. 14 for its next RS‑25 engine hot fire test on the Fred Haise Test Stand at NASA Stennis.
The test window is between 2 to 4 p.m. CDT, and you are invited to watch live!
As we approach ignition, an update will be provided.
For each @NASAArtemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power NASA’s SLS (Space Launch System) rocket to produce more than 8.8 million pounds of total combined thrust at liftoff.

BREAKING: @SpaceX & @FAAnews intend to conduct the assessments to allow 456 Starship launches & 912 landings per year at Starbase, Texas. Weekdays only.
This is 1.7 launches & 3.5 landings per day, but it's the second phase of this plan.
The first phase is only ("only") 100 launches & 200 landings per year. Weekdays & Weekends.
Again, this is very early days, assessments and evaluations have to take place - but it's the first time such a cadence has been written down officially.

It took ship 40 1 hour, 5 minutes, and 27 seconds to get from Starbase, TX to splashdown in the Indian Ocean. It took her 1,879 hours, 22 minutes, and 23 seconds to get back into Starbase. I think the RTLS will take a lot less longer next time.
Our first aerospike rocket thruster. 5 kN (1,125 lbf) kerolox.
Aerospikes are among the hardest rocket engines to develop. Few teams have successfully hot-fired liquid-propellant versions, and none has yet flown to space.
Although the geometry is radically different from a conventional bell nozzle, the governing physics are the same. That makes aerospikes an ideal fit for Noyron, which generates engines from underlying physical principles rather than from CAD drawings.
An aerospike turns the conventional nozzle inside out. Its toroidal geometry eliminates the fixed outer bell wall, which forces a conventional thruster to choose one atmospheric regime.
A sea-level bell nozzle sacrifices performance at high altitude. A vacuum-optimized nozzle cannot be operated safely at sea level.
Aerospikes are efficient under all atmospheric conditions, making them highly relevant for reusable upper stages that fly back from space to the launch site.
Cooling them is the biggest challenge. Our engine uses liquid oxygen to regeneratively cool the inner spike and kerosene fuel to cool the outer shroud. The resulting warm LOX gives the engine a nice Isp boost.
We hot-fired this engine in December 2024. Its early success encouraged us to pursue aerospikes as a parallel track across our engine programs.
