Start Polaris Dawn 26 sierpnia.
Start nadal planowany na 26 sierpnia?
Double Dragons readying for flight ahead of the Polaris Dawn and Crew-9 human spaceflight missions
A little preview of what to expect during our spacewalk from Dragon. Hopefully, we’ll make it look as good as this @SpaceX rendering.
Four astronauts are scheduled to blast off next week on a historic six-day mission to a record orbit, 870 miles above Earth — more than three times higher than the ISS.The mission will also attempt the first-ever commercial spacewalk.
Replying to @DJSnM and @SpaceX A single second stage burn will insert us into the 190 x 1200 km orbit, without a lower parking orbit
So, to clarify is the plan that the dragon will point the nose towards the earth during the EVA. Will the spacecraft be in free drift during this or will there be any active attitude control.The rendering gives a solid sense of what it’ll be like. Dragon’s forward hatch should generally point towards Earth. The Dracos near the forward bulkhead will be disabled & as we cycle crew members between EV1/EV2, we’ll have opportunities to correct attitude or null rotation during the operation.
So, if the Polaris Dawn EVA astronaut is in this position, they're going to have a hard time looking at the earth directly below them. Remember how Astronauts have to lean back to see the top of the F9? In a vacuum the legs will be more rigid, so, no leaning if the feet are secured.
The knees are quite flexible (at least in the ISS/Shuttle EVA suits), so you can look upwards by bending at the knees.But this is the SpaceX EVA suit and all the discussion about mobility enhancements has focused on the arms, no mention of the legs.JI: The knee joints and hip work really well when pressurized.Were there any changes to those from the IVA suit?JI: Yes, the suit is essentially a new design with initial inspiration and learnings from the IVA suit. Beyond aesthetics, almost nothing is the same. Joints, rotators, stiching, MLI layers, cover/restraint layers, boots, helmet, visor, life support, umbilical, HUD/camera and thermal management are all new.

W ten weekend wyruszy na Florydę, gdzie start ma się odbyć nie wcześniej niż 26 sierpnia 🚀 {...}
Touchdown at SLF!!
SpaceX’s Polaris Dawn astronauts just swooped by in five jets here at NASA’s Kennedy Space Center ahead of the Aug. 26 launch @Florida_Today
Super excited to be flying research experiments from my alma mater @CUBoulder - the PI on this eye experiment was one of my bioastronautics professors! Sko Buffs! 🦬 💛
The Polaris Dawn crew will wear smart contact lenses in space to monitor their intraocular pressure, in efforts to learn more about Spaceflight Associated Neuroocular Syndrome, or SANS, as part of a University of Colorado Boulder research experiment.This is just one of 36 science and research experiments from 31 partner institutions flying with the Polaris Dawn crew. Learn all about them here → http://polarisprogram.com/science-research/The crew has put extensive time and effort into ensuring the mission will help expand our knowledge of human health in space.A few months ago, teams released a significant amount of findings from similar projects conducted during the Inspiration4 mission: https://nature.com/immersive/d42859-024-00009-8/index.html"The Space Omics and Medical Atlas (SOMA) package of manuscripts, data, protocols, and code represents the largest-ever compendium of data for aerospace medicine and space biology. Over 100 institutions from >25 countries worked together for a coordinated 2024 release of molecular, cellular, physiological, phenotypic, and spaceflight data."I expect to see similarly impactful data from the Polaris Dawn mission and future Polaris Program missions!
