Falcon 9 flew more missions in ONE YEAR than the entire Space Shuttle program flew in 30 years

• The entire Shuttle fleet:
135 missions from 1981–2011

• Falcon 9 in 2025 alone:
165 launches

SpaceX exceeded the Shuttle program’s entire lifetime mission count by 30 launches in just 12 months

And Falcon 9 also launched more times than every other orbital launch vehicle combined that year

At the Shuttle program’s historical average cadence, reaching 165 missions would have taken roughly 37 years

Falcon 9 did it in ONE

And the hardware reuse comparison is just as insane:

• Space Shuttle Discovery — 39 flights across roughly 27 years
• Falcon 9 booster B1067 — 37 flights in just over 5 years

B1067 first flew on June 3, 2021

By August 25, 2026, the same booster had launched and landed successfully 37 times

A single Falcon 9 first stage came within TWO flights of the most-flown Shuttle orbiter’s lifetime flight count in about one-fifth of the time

What once took decades of launch operations now happens within a single year of Falcon 9 cadence

SpaceX turned reusability into an industrial-scale operation

Today in history: World War II: 81 years ago, on 15 August 1945, Japan's Emperor Hirohito broadcast his declaration of surrender following the effective surrender of Japan in World War II; Korea gained independence from the Empire of Japan.

Dark matter may not interact with light or ordinary matter in any direct way, but its gravity can still leave measurable traces.

A new study proposes using active galactic nuclei, the bright environments around feeding supermassive black holes, as laboratories to probe whether dark matter becomes concentrated near these extreme objects.

The idea relies on reverberation mapping, a well-established technique in which astronomers measure the delay between a burst of light from the inner accretion region and the later “echo” produced when that light is absorbed and re-emitted by gas farther out.

Because light travels at a known speed, that delay gives the distance of the gas from the black hole. By combining that distance with the motion of the gas, researchers can estimate how much mass is enclosed at different radii.

The important point is that, if the central black hole were the only dominant mass, the inferred enclosed mass should remain roughly consistent as different gas regions are measured. But if the enclosed mass appears to increase with distance in a way that cannot be explained by visible matter alone, that can hint at an additional unseen component.

In this case, the researchers applied the method to 14 active galactic nuclei and found that five showed a mass increase with radius suggestive of extra matter around the central black hole.

The statistical strength is modest, around the 1 to 2 sigma level, so it should be treated as a hint rather than a discovery.

The result is interesting because theoretical models have long suggested that dark matter could form dense “spikes” or enhanced profiles around supermassive black holes. Unlike gas, dust, or plasma, dark matter does not collide, radiate, or easily lose energy, so it cannot spiral inward in the same way ordinary matter does.

Instead, its distribution should be shaped mainly by gravity and by the black hole’s growth history, stellar interactions, and galaxy evolution. The preferred profile found in the study has a radial steepness around gamma roughly 1.6, which is broadly consistent with a dark-matter spike that has been softened by interactions with stars.

The authors are careful about the limitations. Current reverberation-mapping mass estimates still carry significant systematic uncertainties, and the inferred amount of dark matter appears larger than some theoretical expectations. That means the signal could reflect real dark matter structure, but it could also be affected by imperfect modelling of the gas, geometry, line emission, or black hole mass estimates.

The value of the work is that it opens a possible observational route to studying dark matter on sub-parsec scales around distant supermassive black holes, a region that is normally inaccessible.

Better reverberation-mapping campaigns, especially using multiple emission lines and improved interferometric data, will be needed to test whether these apparent dark matter buildups are real.

🚀 Les astronautes de la mission Artemis II sont maintenant revenus sur Terre 🌍, ont rejoint leurs familles 👨‍👩‍👧‍👦 (et leurs animaux domestiques 🐶🐱) et repris leur vie (presque) normale, après cette aventure qui les accompagnera maintenant pour le reste de leur vie ✨.

🎢 Le roller-coaster de cette mission incroyable est maintenant derrière nous, et au-delà des photos absolument incroyables 📸, on peut revenir sur un enseignement important de cette mission historique : les gens s’enthousiasment encore pour les grandes aventures scientifiques et de découverte 🌌, comme ils l’ont fait jadis pour l’exploration de l’Antarctique 🧊, la course vers les pôles, les grandes ascensions 🏔️ ou les plongées profondes 🌊 !

On peut même penser qu’il y a un vrai besoin de s’évader du cycle des (mauvaises) nouvelles quotidiennes 📰, et que c’est éminemment important de proposer des activités, des rêves 💭 et des modèles positifs ⭐, comme cette mission l’a fait. En bref : ça fait du bien à tout le monde. La suite sur Linkedin 🔗.

Starship isn’t just a rocket.

It’s the gateway to our Kardashev era. 🚀🌍

[Elon Musk @elonmusk]

Next flight of Starship and first flight of V3 ship & booster is 4 to 6 weeks away

[NASA Science @NASAScience_]

Leaving Earth orbit, ✅. Next up: Finalizing the Moon observation plan.

Artemis II is both a test flight and a science mission. Astronauts, flight controllers, & science teams are working together to squeeze as much knowledge as possible out of the crew’s lunar flyby. ⬇️ (1/6)

[NASA @NASA]

It’s not a straight shot to the far side of the Moon! 🌕

Over approximately 10 days, the Artemis II astronauts will orbit Earth twice before looping around the far side of the Moon in a figure eight and returning home.
