threelonmusketeers, w Polish Space Agency President Sacked Over Falcon 9 Debris Controversy

This was not on my bingo card for this year.

threelonmusketeers, w Testing of Key Callisto Reusable Rocket Demonstrator Component Underway

Glad to see some reusable rocket projects in Europe!

cocolowlander, w When Europe needed it most, the Ariane 6 rocket finally delivered

Arianespace hasn’t publicly disclosed the cost for an Ariane 6 launch, although it’s likely somewhere in the range of 80 million to 100 million euros, about 40 percent lower than the cost of an Ariane 5. This is about 50 percent more than SpaceX’s list price for a dedicated Falcon 9 launch.

With more launch, the price per rocket should decrease, but making it cost competitive will be an important mission if EU wants to launch hundreds of satellites in the future.

threelonmusketeers,

With more launch, the price per rocket should decrease

Should it? Are you referring to amortizing the costs of development, or optimizing the production cost of each rocket? No portion of Ariane 6 is reusable, so it’s not like they can get more launches out of each rocket…

cocolowlander,

Are you referring to amortizing the costs of development

Yes, I was thinking more amortizing the costs of development which will definitely get cheaper the more launch happening, but I guess it’s also possible for optimization of production, although I’m not expecting much from that.

    Those damn Ancient Greeks and their fascist rockets. /shakes fist

    en.m.wiktionary.org/wiki/Ariane

    If your day is just starting, maybe you need a coffee. There’s a distinct difference between Aryan (or Aryen in French) and Ariane (or Ariane in French).

    Different words in different languages sounding the same is a wild launch to a crusade in 2025. Wait until you hear about Ariana Grande… the most Grand of all the Aryans. I know the additional letters won’t fool you.

    Now that’s a stretch.

    Buzztiger, w When Europe needed it most, the Ariane 6 rocket finally delivered

    So glad to see that Arianespace is back in business. At least now it is also abundantly clear that Europe needs its own and sovereign access to space.

    I was so pumped the first ariane 6 launch, I grew up with watching ariane 4 launches and had a huge revell model kit in my room.

    clothes, w CSO-3 launch thread! (Take two!)

    Tout est nominal jusqu’à présent! Interesting how wobbly the fairings looked during separation.

    Fingers crossed the engine relight is more successful than last time.

    clothes, w CSO-3 launch thread! (Take two!)

    I nominate Ariane 6 for the Cutest SRB Award.

    clothes, w CSO-3 launch thread! (scrubbed)

    Apparently there was an issue with ground equipment.

    Due to further operations needed on a ground means interfacing with the launcher, the launch is postponed. The new launch date will be announced following the completion of these operations.

    clothes, w CSO-3 launch thread! (scrubbed)

    Launch postponed :( No details or NET yet.

    Tar_alcaran, w SpaceForest Completes Full-Duration Test of Hybrid Rocket Engine

    Soooo… What’s “hybrid” about the engine?

    threelonmusketeers,

    Fuel and oxidizer are different phases: en.wikipedia.org/wiki/Hybrid-propellant_rocket

    In the case of the SF-1000, it sounds like the fuel is a solid wax and the oxidizer is liquid nitrous oxide.

    threelonmusketeers, w Solar Orbiter ready for close encounter with Venus

    Today’s flyby will be the first to significantly ‘tilt’ the spacecraft’s orbit and allow it to see the Sun’s polar regions, which cannot be seen from Earth.

    Huh, it never occurred to me that we haven’t seen what the Sun looks like from above or below the plane of the solar system.

    threelonmusketeers, w ESA to Launch In-Orbit Refuelling Demonstration Mission

    I wish they mentioned what propellant they’ll be testing. I’m assuming some hypergols or some gas for ion thrusters.

    Venutianxspring, w ESA to Launch In-Orbit Refuelling Demonstration Mission

    This is exciting news

    vzq, w [Eric Berger] Europe has the worst imaginable idea to counter SpaceX’s launch dominance

    On the one hand, it’s euro-ULA. On the other hand, I’m not sure there’s an obvious alternative.

    threelonmusketeers,

    Why not invest in a bunch of the smaller companies like Rocket Factory Ausburg, PLD Space, MaiaSpace, HyImpulse, etc? They won’t all be successful, but if just a couple of them are, the competition would put Europe in a much stronger position than if they were to establish Euro-ULA.

    vzq,

    I’m not sure we can afford an “either or” strategy.

    We should be doing that, we should be doing euro-ULA, and we should be massively expanding (access to) launch infrastructure. There’s only so much you can do when your ranges are literally on the other side of the planet.

    threelonmusketeers,

    There’s only so much you can do when your ranges are literally on the other side of the planet.

    Is suppose French Guiana is a bit far, but Andøya, Esrange, and Saxavord all have plans for orbital launches, don’t they?
