The first controlled ocean 🌊 #landing of a #Falcon9 booster was completed in 📆 April 2014. This was followed a little over a year later by the first successful recovery of a Falcon 9 booster on a ground pad in 📆 December 2015.

So, #reusable ♻️ launch technologies were most certainly available during the design and early development phases of #Ariane6 🇪🇺 europeanspaceflight.com/europe

European Spaceflight · Europe will Introduce a Reusable Launch Vehicle in the 2030sArianespace CEO Stéphane Israël said that Europe will have to wait until the 2030s for a reusable launch vehicle during an interview.

To get enough fuel ⛽ into #orbit for a #Mars 🔴 mission would require at least 10 launches of the #SLS rocket, or about $20 billion 💰. Just for the fuel. To use traditional propulsion, one needs to push the boundaries of #reuse ♻️ and heavy lift rockets to extreme limits—which is precisely what #SpaceX is trying to do with its fully reusable launch system arstechnica.com/science/2021/0

The EU targets clothes and furniture in a crackdown on wasteful consumerism.

Textiles, furniture, tires and mattresses will be subject to much stricter design standards to ensure they last longer, as the EU aims to stamp out wasteful consumption, the European Commission confirmed on Wednesday.

📊 #ESA 🇪🇺 and its member states forked over $4.4B 💰💰💰💰 to develop #Ariane6. Customer launches are unlikely to pay back development costs any time soon.

#SpaceX has invested over $5B 💰💰💰💰💰 in #Starship 🚀 R&D to date. Starship has proven its expendable capability, and the company is focusing on achieving full #reusability ♻️.

#NASA spent a dizzying $24B 💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰 developing #SLS

Payload · Rocket Development Costs by Vehicle: Payload ResearchIn 2008, Falcon 1 became the first privately funded, fully liquid-fueled launch vehicle to reach orbit. Its development cost? Just $90M ($131M inflation adj.).

One might think that #European 🇪🇺 launch officials would have learned their lesson. But not everyone got 🦻 the message. The #Ariane6 will cost 💰 significantly more 📈 than the #Falcon9 rocket, which has similar capabilities. It likely will not realistically compete with a fully reusable Falcon 9. To say #Starship will not be a game-changer represents the same head-in-the-sand attitude displayed a decade ago. These officials #ignored 🙈🙉🙊 the rise of #reusability arstechnica.com/space/2024/06/

Ars Technica · Some European launch officials still have their heads stuck in the sand"Starship will not eradicate Ariane 6 at all."

I did an (automated) historical analysis of the Journal of #Cheminformatics to track #reusability trends over time. Some takeaways:

1. First paper with code in 2018
2. More papers are including code each year
3. Packaging code, applying code quality control (e.g., black), and writing installation docs in an approachable way remains relatively rare
4. Licensing is still not required on all repos?!
5. Something weird happened in 2023 where all good trends reversed 🤷
