I had hoped that looking closer might revel something different than what we already saw. It didn’t. Certainly nothing has materialized yet, which is all I claimed. Do you feel anything of significance has come from the project?

Something has materialised, those "damn spirals and shit" were around way earlier than thought. Maybe it is damn spirals and shit all the way down into the primordial quark soup? Need a bigger telescope to find out but that is just the way these things work. I say go for that bigger telescope, more of this type of research and "moonshots" and all. This is the final frontier we're talking about, the place where dreams go. They may go to die but we'll only find out if we try so try we should. Without this type of research all that is left is to take a microscope to this pale blue dot we live on which would be fine were it not for the fact that the microscope would most likely be taken over by the same prophets of doom who cry woe over all the human race does. Let us look outward as well as inward to gain some perspective, let the doom-criers realise that the universe is big and dark and full of places to park.

Not generally known, I think, but Canada is technically part of ESA. Not a full member, a 'Cooperating State', but there are some benefits. Wiki sez "Canadian firms can bid for and receive contracts to work on (ESA) programmes."

Yeah, and a lot of people also think it's a "EU only" club, but other countries like Norway, Switzerland, and the UK are also members.

ESA isn't even an EU Institution, the EU has its own space agency called EUSPA[1]

Does anyone have any information about the comms package of the Euclid. Getting that amount of data from L1 to Earth must be an interesting challenge.

    For Euclid, the service module provides X and K band communications, with a K band science data rate of ~55 Mbit/s during the daily telecommanding and communications period of 4 hours.

    To store the large data volume that will be accumulated during observations, Euclid will have a mass memory of at least 2.6 Tbit.
https://sci.esa.int/web/euclid/-/service-module

You can get more information by contacting the service module team.

    Thales Alenia Space in Spain has delivered the communications module for the Euclid satellite to Thales Alenia Space’s Turin plant, where it will be integrated with the service module.

EUSPA isn't really a space agency. As the article says, EUSPA gets ESA to do the technical work.

Actually, I grew up in a time where we learned how to read and use maps (think Boy Scouts without being in the scouts). It’s a skill like anything else that takes practice. Using GPS nav is not practice. I’ll use the map app to look at the route, pick out familiar references, then uses those as waypoints. “Three blocks past majorStreetName, turn right” type of things.

So you "learned how to read and use maps", and that's a reason to not use GPS, but you won't visit a time zone website despite not having learned to do time zone conversions? I could see how the former is justified rationally but the latter doesn't seem to be.

Like you’ve never forgot to carry the one or put the decimal in the wrong place. Where you come off with that rationale is beyond me

Anyone else feel as if the title and first few paragraphs give more credit to SpaceX rather than the Euclid team? SpaceX launches things all the time; I feel Euclid is the impressive bit here.

You are right. But it's also weird that rocket launches themselves into orbit become so common they are almost not news. I also start to wonder if anyone calculated or cared what the environment impact might to go from a few launches per year to a hundred or hundreds per year. I mean it's Florida and they are planning to pave radioactive road material so not exactly concerned about the future so feds have to be the g…

Regardless of the environmental impact, rocket launches are the most important thing humanity should be doing

Isn't that most large capital intensive efforts? Also to be fair a lot of US defense and aero contractors have manufacturing partnerships around the world.

> Isn't that most large capital intensive efforts? No. For example in university i was part of a satellite design competition. We couldn’t let Chinese nationals on the team or we’d be breaking the law. There was a list of approved countries a team member could have citizenship from, if not we’d be guilty of violating export controls.

I wonder, could an American join a satellite design competition team in a Chinese school?

> those "damn spirals and shit" were around way earlier than thought

You’re telling me someone with exposure to HUDF saw more spirals and shit longer ago via JWST and said “wow that’s unexpected, who could have guessed spirals and shit would go further back”? And you believed them? If so, I have a bridge to sell you…

Either they have no pattern recognition/projection capability, or (more likely) they’re pretending to express shock at the exact result they expected because it results in more media attention and funding.

Consider, what gets more media attention: “JWST finds more of the exact same stuff Hubble already found everywhere, but this time at the slightly lower frequency for which it is tuned” or “Breaking News! Scientists working on the JWST say they have found signs of early galaxies that have been around for far longer than anyone ever imaged before!”? If you look closely, the two messages are the exact same. But to the media/layperson something interesting is happening in the second one.

Annoying article. Lots of words without saying what precisely it's going to do and how it's better than previous efforts. Much more information (23 thousand words!) is on the ESA website here: https://www.eoportal.org/satellite-missions/euclid Euclid is a deep sky survey space telescope. Like many space telescopes, it's designed to run cold (-140C) to extend viewing into infrared bands ground telescopes can't access.…

Please write more science articles/summaries. This is really well done—great combination of info-heavy while being interesting and readable.
