I've never met a software developer, musician, or artist who didn't have a side project of some sort in addition to their "day job".
You're putting software developer in the same category as musician or artist?!?
Which one of these things doesn't belong?
Writing software is considered a creative act.
I was one of the participants in the Department Of Labor study that decided that,
Jobs that are more than 50% creative are exempt from overtime pay requirements. Software engineering, unless you are job-shopping it as a contractor is considered more than 50% creative. Which means that if you are salaried, you don't get overtime pay.
Personally, when I write software, it's being processed in the part of my brain that processes music. Meaning I literally can't write software if there's music playing at the same time.
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.
Good luck with the gender thing.
Most 56 year old FBI agents show up as 12 year old girls.
We have no idea what would lead Jeremy Archibald Plevin of 2217 Sand Fort Terrace, Blivet Michigan, whose social security number is 555-666-7777, and who only has $9,472 in his bank account and that $100 savings bond his grandfather gave him when he turned 13, and tends to watch an average of 17.3 cat videos per month, and whose favorite search term is 'midget porn' (seriously, Jeremy?1?) to make such unfounded accusations. However, we'd like to assure you, they are unfounded.
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.
If they block WhatsApp... how is my Uber driver going to tell me they're running late?
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.
