Quote from: Svetoslav on 02/23/2023 05:57 pmI couldn't help but notice that this mission is delayed per every three months for another three months. This! One wonders if the issue launch scheduling with higher priority missions bumping it back, general training issues, EVA training issues, or readiness of the EVA suit? Or all of these?

Hey Felix - I hope you are enjoying your summer. We are optimistic about 🚀 towards the end of the year. The EVA suits are in critical testing this month. If they pass then the path gets clear. Then it will come down to weather, which is more challenging later in the year.
Some Updates:- @PolarisProgram - Polaris Dawn is still moving along. We were just onsite for formal updates on avionics, trajectory, suit testing and more. It was great to see 🐉207 Resilience in the cleanroom and get back in the EVA suit again. We did complete a major milestone a few weeks in support of a key objectives, but more details on that later 🎶📡. As for updates on other Polaris missions, we hope to learn more on Polaris II by the end of the summer. For those looking for more regular updates, please know Polaris is a development program & what SpaceX is working on takes time and in many cases hasn't been done in decades or never before. Personally, I feel fortunate to watch and learn from them - they continue to make the world more interesting by the day. [...]
We’re still hoping for the end of the year, but I suspect it will probably slip into the beginning of next year.

Polaris Dawn is looking like Q1-2024. It is a development program and new technology takes time to implement. The EVA suits being a big driver of the timeline. No updates from NASA on Polaris II, but we are still hopeful we can help out Hubble. We have a great plan to extend the life and capability of the exploration platform at really no cost to the government.
Great fighter jet training weekend for the Polaris Dawn crew
These flights allow for high g-force familiarization and crew resource management in a high-consequence environment 🚀
Excited to test out Starlink for the first time during a human spaceflight mission with Polaris Dawn!
Hello Felix! - I am at SpaceX today for EVA suit testing. This is an evolution of the dev suits.- Suit pics will be released in advance of mission but I don't know when.- ~April is the goal to launch & the pace of training is accelerating. Merry Christmas & Happy Holidays.
- Building and certifying new EVA suits for starters. There is a big difference between an IVA suit that is a last line of defense in the vehicle vs. suit engineered from the start to be exposed to vacuum outside the spaceship. That includes suit changes for mobility, life support redundancy, sun glare, some resiliency to MMOD. - Similarly, the vehicle was designed to go to vacuum only in an emergency. There are changes to software and ECLSS hardware to make an EVA a nominal operation. - Laser-based communication over the Starlink constellation is not an easy task either. Its not just turning the router switch to the ON position. Every draco firing could break a link. - We are flying higher and closer to the Van Allen belts than anyone has gone since Apollo 17. The radiation exposure during those orbits over a few days is the equivalent to months on the ISS. Avionics don't like radiation which means there is a lot to analyze and sim to get right. SpaceX engineers are doing an outstanding job tackling big problems very quickly.
Great update from @elonmusk including a rendering of Dragon's EVA config w/mobility aids. Elon highlighted the challenge of building an EVA suit but also the importance for future lunar & Mars applications. The suits we will test on Polaris Dawn represent a step towards that goal
And we're also going to launch Starlink on that flight.
This is really going to be another great milestone, to actually be able to have someone floating out there in the vacuum of space and come back. And we want to have a spacesuit that you can walk around in. You want to be able to walk around on the Moon, walk around on Mars. So having a high-mobility spacesuit that actually isn't crazy expensive, ideally, that you can walk around in comfortably is a big deal. It's actually an important thing that needs to be developed and ultimately made in large numbers, because if we send, say, a million people to Mars, then that's a million Mars suits that you need. So we'll have to make a lot of these things. And we're also going to launch Starlink on that flight. So, then coming to Starlink, this is almost a whole separate company, but we're basically rebuilding the Internet in space, which is pretty wild. ...
Did anyone else catch this one-liner dropped by Musk as he was transitioning from Polaris Dawn to Starlink?Quote from: Elon MuskAnd we're also going to launch Starlink on that flight.See time 27:16 of Musk's 2024-01-24 SpaceX company update:twitter.com/SpaceX/status/1745941814165815717He had digressed slightly into the subject of Mars suits, but "this flight" was clearly a reference to Polaris One.Quote with context, starting at 26:23:Quote from: Elon MuskThis is really going to be another great milestone, to actually be able to have someone floating out there in the vacuum of space and come back.

Or, is it possibly they will deploy a Starlink satellite or two as close-flyers, keeping company with Dragon and providing the laser interconnect to the Starlink network while maintaining an RF connection to Dragon. (It would be very cool if the close-flyer was also equipped with cameras to record the EVA from its perspective!)
<snip>A close flying Starlink is probably the quickest and easiest way to provide a laser ISL for the Polaris mission, but how can Crew Dragon interconnect to to the close flyer at high data rates with little or no NRE? Existing Radio? A Starlink user terminal? CAT5 cable ? If radio, how/why would the Crew Dragon's radio system have any faster connectivity with the close flyer than with the rest of the Starlink system?I don't know if a Starlink user terminal could be used without modification. Presumably the directional phased array antenna could be replaced with an omni. The protocols may have been created with an implicit assumption about the minimum distance (i.e., minimum delay) from user to satellite. The satellite also uses a directional phased array antenna for its user links that may also need to be replaced by an omni, but that would be hard if the antenna is also the ground link antenna. Kill the ground link since you intend to use ISL? but that requires the Starlink to enter the net using only ISL, which is also not a design requirement for the protocols.Any good engineering group could solve this in multiple different ways with a new design. I'm asking if there is a solution that needs at most minimal new hardware and software design.
