Would astronauts’ kidneys survive a roundtrip to Mars?
  • You can’t protect them from galactic radiation using shielding, but as we learn more about renal biology it may be possible to develop technological or pharmaceutical measures to facilitate extended space travel.

    Is there a physical reason why shielding is ineffective? Seems like some tanks of water (which a Mars mission would need anyway) or some slabs of lead or tungsten would do the trick.

  • What DART has taught us so far
  • The conclusion was clear: Humans can indeed move an asteroid. If we detect a dangerous space rock headed toward Earth, knocking it off course with a spacecraft is a potential option.

    This gives me a nice piece of mind. I know the asteroid impact to exceedingly rare, but it's one fewer threat we have to fear now.

  • Pentagon embracing SpaceX's Starshield for future military satcom
  • Glad to see that the DoD are stepping up to fund and operate a separate constellation of satellites. Putting SpaceX in a position where they had to make real-time decisions on military communications seemed like an unfortunate situation for everyone, SpaceX included. Hopefully this will rectify that.

    KSC: Zack highlights notable points in the environmental impact statement for LC-39A, and posts additional thoughts.

    • 35 booster engines, 9 ship engines
    • Up to 44 launches per year with both pad and drone ship landings
    • Separate catch and launch towers
    • Liquid methane, LOX, and LN2 produced on site.
    • 3.8 megalitre water deluge planned, 2.5x larger than current Starbase deluge.
  • Following the other post, which lemmy.ml communities don't have alternatives on other instances?
  • where we should host the autonomous and self driving technology community and the whole time it was bloody obvious. @lugh@futurology.today can we host it on your instance?

    I asked the futurology admins about adding additional communities that fit the futurology theme, but they seem uninterested. I'm not sure why, as having what is essentially a single-community instance seems a bit strange to me, but it's ultimately their call.

    @Lugh@futurology.today and @Espiritdescali@futurology.today, would you reconsider increasing the number of communities on your instance, provided they fit the futurology theme?

    Could there be a more "Brady" news story?

    Why SpaceX Plans To Jettison The Interstage On Flight 4

    TL;DW: Zack posits that the additional mass of the hot stage ring pushes the total mass of the booster close to (or over) the limit of what the booster can land with, based on the amount of propellant which can be stored in the current design of the landing tanks.

    The video is much more detailed, and definitely worth a watch!
