I don't need to stand by the rotation theory. However, the 2.5 degrees that the Earth rotates are about equivalent to the downrange distance.
The first stage is going about 1/5 of the target LEO orbital velocity at separation. While you might well model the trajectory as a parabola over flat ground, given the lack of fuel I would expect that SpaceX puts a lot more care into their trajectory. So far I've failed to attract the attention of the person responsible for Flight Club, the most trusted modeling of SpaceX flights, but I'll message him directly.
Well, Alastair, you should probably not get snotty and ad-hominem, unless you want me to comment on how a one-time sci-fi author and the Unix guy at Dish doesn't really have more authority than the random person one might find in the SpaceX group on Reddit.
It happens there are a few people over there who are rocketry professionals, have the math, and have followed SpaceX long enough. So, sure, their opinion can indeed be trusted.
So far, we have a suggestion from one of the lesser folks there that raising the apogee takes advantage of the Earth's rotation. We'll see if we get the attention of the right people.
Probably more a question of old school businesses who just don't want to get it? There are too many of them in France and too much paper work and risk adversness to create a healthy startup culture.
And should add is only really effective for popular content. Less popular content (where there is only the original seeder sharing) works out to be no better than an http file transfer.
It is, since how otherwise do you describe "a large amount of water that moves very quickly in one direction" (m-w entry)?
While I didn't find the news article I thought I had read, I did find the Chrome extension 'The Great Suspender', which indicates it 'Automatically suspends unused tabs to free up system resources'. Just installed it in the hope it actually helps - BTW I have no involvement in the creation of this extension, but it does appear to be open source: https://github.com/deanoemcke/...
Wasn't Google Chrome (the browser) meant to introduce a sleep mode to background tabs? Does anyone know whether that was introduced or whether I am confusing the browser product?
At the same time Google Chrome often shows up as 'using significant energy' on my MacBook Air, under MacOS 10.11.5. Has anyone done any profiling to see what aspect of Google Chrome is consuming the CPU? BTW I am one of those tab hoarders, but apparently not as bad as some.
Here's an illustration of the boost-back to RTLS trajectory. You can see that it very definitely goes up. And to prove from observation, you can actually see where the two trajectories separate in photos from yesterday's launch. It's a rather dim curl up, and another continuing East, in Jason Ruck's photo and John Kraus's photo.
At the speed of stage separation, they rocket isn't going fast enough to stay in orbit, but it is definitely in the regime where orbital mechanics has a macroscopic effect. If you think about it, this is going to be the case at some reasonable fraction of orbital velocity.
This is just like the way people whined that color film had ruined the medium, and the ones before them who whined about talkies and yearned for the days of silent films.
I started at the NYIT Computer Graphics Laboratory in 1981 and left Pixar in 2000. These days I produce or am on screen once in a while.
While I was at NYIT they weren't story oriented, and thus all you see of them is demos. Pixar, on the other hand, always put story first. We knew that we could not make a film stand up on effects alone.
Today, a good 3D animation house can make absolutely any scene they like. And thus there isn't anything special about doing so. It's there if it needs to be there to tell the story, and not otherwise.
To return to landing site it goes UP, back, and down. Orbital mechanics.
East takes you out, out takes you west, west takes you in, in takes you east, port and starboard bring you home.
