  1. Taking some inspiration from today's #APOD, here I've used #Stellarium to simulate the apparent trajectory of the #Sun if it were photographed at the beginning of each month at midday where I live during this whole year. The characteristic figure-of-eight path is called an #Analemma. The individual frames were made into an #AnimatedGif using #Gimp.

  5. 2/ The #C3 #CS3 counter is currently running a few days ahead of what was the record-breaking 2023 trajectory.

    The #C6 #CS6 counter is about 300k higher than any previous June score - historically this counter has been the less reliable. Fingers-crossed, its OK this year

  7. @uwuhaeckse #DSS43 📡 is the only antenna in the #NASA #DSN that talks to #VGR2 🛰️ because its flight trajectory had it head off ‘below’ the plane of the ecliptic (‘south’ from earth’s perspective), and 43 is the only antenna in the southern hemisphere powerful enough to communicate with it. The 70m antennas in the northern hemisphere don’t have line-of-sight, but even if they did they could only receive data 😢

    #VGR1 headed off ‘above’ the plane of the ecliptic, so all the 70m DSN antennas have line of sight & can all still Rx. but for Tx we need to use 43 ‘coz it’s the only 70m with a 100kW S-Band transmitter that has enough juice to send commands to the spacecraft. Rx from VGR1 is handled by arraying multiple antennas to create a larger effective (virtual) dish size, ‘coz it’s further away than VGR2 - remember that these spacecraft only have transmitters that push out ~23W (rated output, I expect they’ve fallen off a little over time). by the time it reaches earth, the signal Is about a billionth of a billionth of a watt (attowat) 🤯 that’s why they ask you to turn off devices 🚫📻 to “help us listen to whispers from space” 🤫

  8. The toolbox continues to grow.

    New in: stop detection and trajectory styling

    I’m continuously testing the algorithms integrated so far to see if they work as GIS users would expect and can to ensure that they can be integrated in Processing model seamlessly.

  14. Very happy to share our new paper, showing that the ontogenetic trajectory of trabecular bone tracks neural development and life-history variation among humans and non-human primates. If applied to the fossil record, could lead to new ways to interpret the evolution of developmental trajectories of the brain. Great work by Jaap Saers, and coauthors Tim Ryan and Adam Gordon.

  15. I often look at papers where authors used a lot of effort to shoehorn a #LongitudinalAnalysis into a trajectory or #MixedModels that do not quite the job the team wants.

    Analysing longitudinal data (esp. w time-varying covariates) via G-Estimation is an alternative for consideration:
    journals.sagepub.com/doi/full/ #Tutorial

    The underlying thinking is not entirely different, but often one needs only a little step / laterality to get a new view on an analysis problem.

  18. @statsguy These data being human-readable shall be most informative! Given the trajectory we're on I can only see such #WT35C events occurring more and more frequently... People need to able to see that.

  19. Finally completed the first version of full circle support in @movingpandas :

    Read MF-JSON (MovingPoint or Trajectory encoding) as TrajectoryCollection and write it back out to MF-JSON MovingPoint encoding ... interopterability success 🎉

  20. The #Starship second stage lit up its six Raptor engines in the midst of separating from the #SuperHeavy first-stage booster. Launch commentator John Insprucker said the hot-stage 🔥 separation was “just beautiful, exactly what we were looking for.” 👍
    The second stage, known as Ship, continued onward on a #trajectory that #SpaceX said would have reached #orbital speeds. 👍

    After the first Starship / Super Heavy test flight, #SpaceX installed a water-cooled 💦 steel plate at the #LaunchPad to reduce the damage done by the booster’s blast, and that system appeared to work as planned. 👍 cosmiclog.com/2023/11/18/space
