threelonmusketeers, w ESA Vega-C BIOMASS Launch Thread

Can’t wait for the next launch!

saltesc, w Europe funds inflatable satellite drag sail demonstration

The system is designed to be initially 20 square centimeters in size but would inflate about 7,500 times larger to around 1.5 square meters, increasing atmospheric drag to accelerate deorbiting.

The only thing more impressive than seeing that expand out would be watching them pack it down.

threelonmusketeers,

Now I’m imagining bits of the sail bulging out of the rocket fairing like a hastily-packed sleeping bag at the end of a camping trip.

saltesc,

After decades of camping, I only recently found out most (modern) sleeping bags are actually meant to be stuffed in their bags, not rolled up. Just kinda keep stuffing it in there and they seem to naturally fill gaps better than if they were rolled up first, so they’re easier and much faster to pack away.

There’s a random LPT for ya.

threelonmusketeers,

Huh, TIL. Thanks!

    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.

    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! (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.

    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.

    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?

    ElectroVagrant, w European Launch Startups Send Open Letter to ESA Outlining Key Priorities

    It is crucial to ensure that the following already agreed-upon elements remain unchanged through to implementation:
    […]
    3. A Shift in Mindset – Need for Speed: To compete globally, Europe must embrace a cultural shift towards speed and innovation. Laws and regulations should be evaluated based on their ability to accelerate progress, with speed as the primary KPI. […]

    This doesn’t seem like a great idea when dealing with rockets…It’s wasteful, immediately hazardous to any crews, and eventually (if not also immediately) harmful to the environment with any wreckage and other pollution that may be produced. And this is from someone that supports space initiatives and research.

    It’s wasteful, immediately hazardous to any crews, and eventually (if not also immediately) harmful to the environment with any wreckage and other pollution that may be produced.

    Interesting, I interpret “Europe must embrace a cultural shift towards speed and innovation” in almost exactly the opposite way.

    Ariane 6 was essentially an outdated design before it even launched. All of the major American and Chinese launch companies are operating or developing reusable rockets. The launch startups which wrote the open letter are some of the only European organizations actively pursuing reusability, something Arianespace has ignored for far too long.

    Smaller than a strawberry seed, this tiny signal amplifier was produced by the European Space Agency to fill a missing link in current technology, helping to make future radar-observing and telecommunications space missions feasible.

    “This integrated circuit is a low noise amplifier, measuring just 1.8 by 0.9 mm across,” explains ESA microwave engineer David Cuadrado-Calle. “Delivering state of the art performance, the low noise amplifier’s task is to boost very faint signals to usable levels.”
