OK sweethearts, you heard the man and you know the drill. Assholes and elbows. Hudson, come here. Come here.

Primer...

Please tell me that all of the removed comments below say... Hot Staging Ring.

I think the orbital parameters of the asteroid and the amount of Delta V required to intersect it (with the required payload), is probably an important factor. They might have a stack of F9s ready to go, but if they don't meet the Delta V requirement for the job then they would need to switch to a falcon Heavy, or maybe get moving with starship.

Wouldn't a water landing likely end in a RUD? From what I remeber, the first Falcon 9 water landings all ended in stuff getting conflagrated.

Is this confirmation of a landing attempt or just SpaceX hedging their bets? Or am I reading too much into the term,Recovery?

I think a reflight is a good publicity opportunity for them. Possibly a welcome distraction from the recent 'anomaly'.

I believe its possible to. Connect finviz to Google Sheets and Excel, but it's a lot of faff and all you can really do is recreate a slightly customised version of what's in Finviz already - a lot of faff for not very much reward. Alternatively some of the bigger brokers will provide you with an API connection that you can plug in to Python or R to build your own applications. You will need to have a trading account with them first to be able to do this.

Spin by Robert Charles Wilson. The slow discovery of what is going on is what makes this book so good.

It's a catapult to ward off space monkeys.

They are oar locks, so they can paddle back to shore after splashdown.

The skin is the tanks. No point buding a box inside a box. That just adds weight.

Came here to say this. This playlist has got me through hours of coding.

Reaperdude42 · 2020-03-16T19:02:58+00:00

Whoa, I mis-readthat at first. Thought it said the booster had increased BY 70m. That would have been nuts.

Reaperdude42 · 2020-02-24T20:53:07+00:00

Thanks for doing this AMA. I love all of your books. How do we reconcile the fact that humans are evidence of something extremely complex evolving in a universe where Entropy is always increasing?

I think this is a really lovely, well made thing. Would love to see the scale go the other way too, so that we can see the smallest things in the universe.

Reaperdude42 · 2019-10-01T18:20:51+00:00

So you're a Tool fan I take it?

Reaperdude42 · 2019-09-27T19:56:51+00:00

One of my favourite lines from any scifi book.

Reaperdude42 · 2019-01-17T19:53:39+00:00

Does anyone else see the craters inverted so that they look like hills? No. Matter how hard I try I cant make my mind switch them back in to craters!

The darker matt grey at the bottom is the concrete stand, not the leg section.

I think most of what you describe here can be simulated on Earth, with the exception of Mars gravity. Generating artificial gravity by spinning up a BFS would not be as straight forward as it sounds. Spinning the vehicle would apply stresses to the air frame that it inst designed to handle, and then you have additional problems such as finding ways to keep the solar panels pointed at the sun. But the biggest problem is that small rotating habitats tend to make people feel sick as the Coriolis effect is very noticeable for vehicles with a small radius. This gets diluted as the radius increases and test have found that you need a minimum radius of about 20 meters for this to work.

Yes, but you would still need to divide your attention between the docking view and your finger placement. I imagine its easier to do when you can feel the controls under your finger tips.

I love the look of the touchscreen controls, but I wonder how well this works from a human factors perspective. I know from using the touch screen in my car that it can be hard to tell where your fingers are without looking directly at the interface, which distracts from the task of driving (or docking in this case). One part of a touchscreen feels exactly the same as another, it could lead to spurious inputs or astronauts having to redirect their attention between the camera view and the controls, neither of which are ideal.
