Artimis SLS rollout from VAB in Florida begins in a couple of hours. If everything goes as planned, it will never be rolled back in but will soon be launching the first human rated capsule to Lunar orbit since December 1972. (A day I still remember sadly knowing even as a child that it was the final moon mission)

Simply put: Earth is spinning faster and here’s how it could impact your lives

If you feel like time is passing by at a faster pace, it is not just in your head!

Earth is meeting its targets even before its deadline, becoming the latest ‘victim of hustle culture.’ Earth recorded its shortest day last week, ever since scientists began using atomic clocks to measure its rotational speed.

Holy moly crap....

Why is the Earth rotating faster?

While there are many reasons contributing to Earth’s faster pace, one of the reasons is the melting and refreezing of ice caps on the world’s tallest mountains. Due to this, there’s less weight on the poles.

Back on the pad for the final time?

I am conflicted by Artemis. So glad we are finally making the decision to return to the moon after all these DECADES. But aghast at the wastefulness of still using disposable boosters. We are still still meeting a 1960s era mission requirement using 1960s era technology
And darn it, the booster is dang ugly. Never have been a fan of that ugly burnt Orange insulation and stubby upper stage. The Saturn V was beautiful, this thing ain’t
But hoping for success. We should be able to get back to the moon while at least a handful of the original moon walkers are still alive

We should not have stopped in 1972. We would have been permanently on the Moon, visited Mars and probably been planning a trip to the outer solar system by now had we kept pushing.

As the rotation speed picks up, people who watch the Earth’s rotation and world’s clock for a living, will have to introduce a leap second to keep up with Earth’s pace and synchronize clocks with it.

Horrors! How will we ever adjust?

OK, if the earth is spinning faster, why do we add a leap second? Shouldn't we deduct a second so that we're in sync with the faster spinning earth? I'm not visualizing this

I'm sure there is still some NASA scientist that says reusable rockets are impossible.

They were actually scientists that said what Elon was wanting to do in regards of landing rocket boosters would never work.

Standard cell service via the Starlink cloud?

That could be a game changer if they get the speeds up. Though I'm wondering what it will do to battery life? The signal has to be a lot stronger to get to LEO.

T-Mobile and SpaceX Starlink say your 5G phone will connect to satellites next year

T-Mobile says it’s getting rid of mobile dead zones, thanks to a new partnership with SpaceX’s Starlink satellite internet, at an event hosted by T-Mobile CEO Mike Sievert and Elon Musk. With their “Coverage Above and Beyond” setup, mobile phones could connect to satellites and use a slice of a connection providing around 2 to 4 Megabits per second connection (total) across a given coverage area.

That connection should be enough to let you text, send MMS messages, and even use “select messaging apps” whenever you have a clear view of the sky, even if there’s no traditional service available. According to a press release from T-Mobile, the “satellite-to-cellular service” will be available “everywhere in the continental US, Hawaii, parts of Alaska, Puerto Rico and territorial waters.” The service is scheduled to launch in beta by the end of next year in “select areas,” and Sievert says he hopes it will someday include data.

Musk provided a bit more detail by saying that, unlike usual internet service, it could work without access to Starlink’s full satellite constellation. By limiting it to certain messages and services, as well as only in places that don’t currently have cellular connectivity, it could use a more intermittent connection for “basic” coverage, although you might have to wait 30 minutes for a message to go through.
