    Thanks anyway. :smile2:

    I didn't know there were radio telescopes that big.

    Being honest, I didn't know the man. I had to google it. Rest in peace.

    Yeah, I'd kind of assumed he died ages ago, in 80s or something.

    Um, excuuuuse meeeeee... o_O

    I know it's not new. I mentioned it because we were talking about this these days, and they just posted that article, but yeah, I know it doesn't tell anything new and that most of you are quite updated.

    Oh, no problem. I also thought the info in the article wasn't something to be surprised of. That's why I said that my intention was just to point out a coincidence regarding the subject we were talking about here. :mrgreen:

    I see they're going for reusability, too. Maybe this will become a global trend, after all?

    Oh, and cool booster retrieval system, even though we didn't see it yet. Spacex's is cooler, IMO. :mrgreen: Nothing beats a booster landing on its own... until we get full, self-contained spaceships (oops, I wrote spaceshits at first), which I hope I will live to see.

    Yeah I have my doubts about that retrieval system.
    I mean US did similar with Skyhook back in the day but its one thing hooking a camera film capsule with a C-130, something else hooking a 1st stage rocket with a chopper.

    Maybe they tried to do something different from Spacex, so they don't look they copycat... or maybe they don't have the means to reproduce the same system. At any rate, if Spacex's formula is the most efficient, other companies will follow (those that aren't already).

    Also, recently:

    Electron is tiny for an orbital rocket. It has up to 250kg of payload. They simply don't have the margins to do hypersonic retro propulsion + propulsive landing.

    Any of the smallsat launchers wanting to do reuse SpaceX style will need to go quite a bit bigger with their vehicles.

    Lockheed Martin demoed it a couple of years ago. They own part of Rocketlab, so they've probably just nabbed that data/tech.

    SpaceX Starhopper last untethered test yesterday! 150 meters high. Impressive!


    The next tests will be with Starship prototypes, I think.

    Oh, and...

    Call me crazy, but something tells me that he's not referring to all America, though... ¬_¬ (you know, the continent)

    The assembly of the first Starship prototype is complete. This is Elon Musk's presentation, with updated info on Starship and Super Heavy:
