BoringHusband, w I want to be among those who deeply thoroughly understand & can accurately predict the path of future eclipses because this is amazing.

Math.

LemmyKnowsBest,

Yesss. I waaaaant it in my mind and in my souuuuuul.

Sprawlie,

Fun Fact:

They discovered Neptune by math. They studied the orbit of Uranus and noticed anomalies in the mavity, so they postulated there must be another planet. Using math, calculated it’s path, aimed their telescopes, and voila, Neptune.

I am terrible at math, so I can’t explain how it works. But it’s all about physics. en.wikipedia.org/wiki/Classical_mechanics is probably a good start.

Did I miss something? I couldn’t see where they said “will soon” and what that means.

Muscar,

“In early March, NASA announced that construction and testing of the three CADRE rovers was complete and the trio was ready for integration with Intuitive Machines’ Nova-C lander, which will deliver the mini explorers to the lunar surface later this year or early next year as part of the company’s third lunar lander mission, IM-3.”

At the end of the article. And here’s the website for the project with more info: www.jpl.nasa.gov/missions/cadre

Perfect, thanks.

prole, w [Eric Berger] Seeing this eclipse is probably the highest-reward, lowest-effort thing one can do in life

It’ll be interesting to see just how little this is in the national news given the location of the path compared to times when the path of an eclipse has gone through major metropolitan areas in the northeast or west coast. Almost an indirect measurement of science education in each area. I didn’t even know there was an eclipse coming until this article.

Or maybe I’ll be proven wrong…

XeroxCool,

That sounds more like a normal population density representation. Everyone hears about CA or NY news because they have more significant national and global impacts, through number of affected people and volume of business. News about the state of Arkansas is less visible since it has less population than any of the major cities in the aforementioned states.

Despite that, I’ve seen plenty of coverage specifically because, compared to the 2017 American total solar eclipse, this one is more accessible to a vastly greater population: namely DFW TX and NYC. NYC has a longer drive, but the northeast is an incredibly dense portion of the country.

Shdwdrgn, w Northern lights predicted in US and UK on Monday night in wake of solar storms

But the solar flare was yesterday, if there was going to be any good viewing of auroras it would have been last night, or more likely a couple nights ago (from US time zones). The peak of it occurred shortly after lunch yesterday and it’s calmed down back to normal today.

mihnt,

I mean, these are highly funded government agencies reporting this from both sides of the planet. You know something they don’t?

Shdwdrgn,

The agencies were correct about the information, however unlike OP apparently I know how to adjust for time zone differences. Monday morning in Australia is still Sunday in the US, so yes that would have been the correct time for the warning. But this article was posted here a day after the event occurred, all of the warnings expired, and the Kp index had dropped back down to more moderate levels. At the peak of the event the Kp index reached around 8.0. When I posted my comment yesterday it was sitting at 1.66, well below the threshold for seeing auroras anywhere in the continental US. If you had any chance of seeing auroras here it would have had to be Sunday night, not Monday night.

If Constellation on Apple TV is right, then it’s an indication that the person has become quantum entangled with their alternative self in another universe.

Good show btw if you are looking for something more psychological with a sci-fi background.

Rubisco, w Big, doomed satellite seen from space as it tumbles towards a fiery reentry on Feb. 21 (photos)

In an update posted on Sunday (Feb. 18), ESA said that the rentry ERS-2 is expected to take place on Wednesday (Feb. 21) at 10:19 a.m. ET (1519 GMT), plus or minus around 19 hours. This uncertainty is due to the “influence of unpredictable solar activity, which affects the density of Earth’s atmosphere” and can therefore change how much drag pulls on the satellite on its way down, ESA wrote.

Plus or minus 19hrs due to the sun’s effect on the density of the atmosphere. Mind blown.
