Reply to Hello everyone . I am very interested in space megastructure. such as mckendree cylinder or bishop rings. But suppose we built it. How can a spacecraft dock with it ? Knowing that these huge structures rotate at huge speeds to generate a gravitaty similar to Earth's by Dizzy_Ad3353

Either have a docking arm on both sides that align with the axis of rotation, or have a counter rotating docking ring with ports at regular intervals.

Docking at the spin axis will definitely not work. Or you accept that you will only ever have a maximum of two ships docked simultaneously.

But this is obviously impractical for anything larger than the ISS.

Look up my older posts how to solve this.

Reply to comment by Postnificent in Why don’t we use Venus as a dumpster? by Postnificent

>Which should be our first order of business with these new nuclear propulsion systems they want to use to explore mars.

The main problem here is that those nuclear engines are far less effective than the mass media wants you to believe.

The technology is extremely expensive and requires large volumes of hydrogen which is incredibly difficult to store in space because of the permanent sunlight. It will just evaporate.

In essence its far cheaper and faster to go to Mars via chemical engines.

To send stuff to the sun however requires far larger quantities of energy.

Reply to comment by CFCYYZ in Could we terraform mars with our current technology? by TheZogKing

>While we dream of making Mars look like Earth, we are busy making Earth look like Mars. Terraform Earth. It's easier, cheaper, faster, with benefits to every human.

Why tf is this the standard post every time anything about Mars gets posted?

What we do on earth is completely irrelevant to what we (can) do on Mars.

It's so sad to see that people can't hold two thoughts in their heads simultaneously.

It's always either. Either do something on Mars OR save earth? Why? Do you actually think humanity is unable to do more than one thing at a time? Or do you also advocate for stopping child cancer research until climate change is fixed?

Reply to comment by rocketsocks in Rocket Lab targets $50 million launch price for Neutron rocket to challenge SpaceX’s Falcon 9 by cnbc_official

It is insanely so. x100 more difficult. If it wasn't, someone else would have landed an orbital rocket by now, when they landed a suborbital in the 90s.

What many different methods of landing the rocket did they try? Does Rocket Lab knows all of them?

Oh wow, SpaceX secret sauce is getting things done and execute!! Wow that's not what we call secret sauce!

I'm not sure you've noticed, that Gwenn and Elon have both said they will do around 100 Starship launches before land on the moon with HLS. So...that kind of mean a hell of a lot of launches with Starlink and customer's sats. And they don't need orbital refilling for that.

Cause SpaceX does know how to land and reuse. And Starship's design is made with lessons learned from F9. Rocket Lab and Neutron don't have lessons learned. That's why so many people believe Starship is easier for SpaceX than Neutron for Rocket Lab. And SpaceX does work faster. Rocket Lab will need at least 3 years for first launch, another 2 for first landing, another 2 for first reuse. So 7 years to make reusability and that's the minimum time. Starship will fly in a couple of months. So....
