Space In General

Based on the mass suicide of whales and the current alarming status of sunspots, I'm predicting high probability of a massive earthquake and tsunami within the next few days.

"Six days before the massive magnitude-9 earthquake that triggered the devastatingMarch 11, 2011 tsunami in northeastern Japan, 50 melon-headed whales beached themselves in the area. This week, over 150 melon-headed whales beached themselves on two beaches is the same vicinity. Is this another warning from the whales? Will anyone listen this time?

On April 9, 2015, almost 160 melon-headed whales (Peponocephala electra), members of the oceanic dolphin family related to pilot whales and pygmy killer whales, were found beached on a 4 km (2.5 mile) section of beach in Hokotashi City, Ibaraki Prefecture."

AR2321 has an unstable "beta-gamma-delta" magnetic field that harbors energy for strong flares. The new sunspots boost the odds of an eruption even more. NOAA forecasters estimate a 55% chance of M-class flares and a 20% chance ofX-flares on April 14th. Solar flare alerts: text, voice

On a somewhat related note, there were a few quakes in LA a couple days ago. And that area is due for a big one...
 
Finally found out I can use Stellarium while not connected to the Internet.. This is gonna make shooting star trails and in general shooting the stars at night 9.99x10^999999999 better...
 
Looking at the landing video, it looks like there was a big plume from a nose jet for a long time, trying to save it, then a puff of smoke and it fell. I'm thinking it ran out of juice for the nose jets.

OTOH, I can think of no project anywhere ever that has tried to land something this tall on rocket thrust. We've had landers, both robotic and manned, as far back as the 60s, but they were all at least as wide as they were high, if not twice as wide as high, and the ones I'm thinking of were meant for 1/6 gravity! Landing that tall stick on a rocket plume in Earth gravity is simply a goofy balancing act!

This is a good highlight from the YT comments:

"I was really rooting for that valiant RCS thruster to snatch victory from the jaws of defeat, but alas it was not to be."

Making predictions off a one-time event now?

It is highly possible that you have a species that travels in groups of hundreds and so when one gets beached a lot do. Maybe sunspot activity is related. Maybe it isn't. I wouldn't start buying into predictions based on so little data. In 1988 my entire region was supposed to suffer a giant earthquake. Some scientist used similarly odd prediction techniques. We had earthquake drills and everything. It still hasn't hit today.

Predicting a higher probability, yes. But not an event necessarily this one time. And based on much more than just one prior event. There is sometimes a correlation between space weather and earth weather. But...

Here's a question for the physicists and astronomers amongst us:


The Earth and the atmosphere as a whole rotate together at the same rate. Why?

Answer: Billions of years ago, the Earth and the atmosphere were set into motion, and inertia keeps them going despite internal friction and the Moon slowing them down. Angular momentum is conserved between the atmosphere and the crust.

True or false?
 
It's held in by gravity, but it's not completely fixed in place. If it was there would be virtually no weather besides sunshine with no wind.

I think, kinda sorta. :) (This is a thought experiment, right?)

The formation was from the material falling into a spinning vortex of material, and that spin meant that whatever formed (a planet) was spinning. As it outgases, those gases don't suddenly stop because they hit the brick wall of space...... They are on a ballistic trajectory based on the velocity with which they were ejected, just like a rock from a volcanic explosion would be. Depending on that velocity the gas molecules escape to space, or fall back to the earth somewhere.

You get enough of those gas molecules hanging around, you get an atmosphere.

Still, the biggest influence on the fluids of atmospheric gases and surface liquids is the gravity of the planet itself. The combination of gravity, spin, and heat generate all sorts of motions, and the influence of gravity from outside affects thos fluids as well, giving us tides.

Which brings up a question I've wondered about, but never looked in to until recently: Does the atmosphere exhibit tidal behavior? Turn out it does! It seems that heat still drives atmospheric motion more than gravity does, though. From what little I've actually read about it.

I guess your question is: Why don't we have surface winds on the order of a thousand miles per hour as the planet rotates under a fixed-in-space atmosphere?

Well, that would be somethin', wouldn't it? :)

Well, we're on the surface and so in the boundary layer. Stuff is going to be slower (relative to surface, but it will also accelerate things toward the speed of angular rotation) down here, and even slower in the presence of things like mountains.

Air speed is also going to depend where the planet is hot and cold too.


EDIT

To add, here is a nice viewer for Earth winds and currents:

Realistically it rotates with the earth for the same reason that you do we don't just fly off, likewise the atmosphere doesn't just sit there or spin around on its own accord, it would make logical sense for it to spin with the earth.
Not sure about the last part though but for the first part it's true.

SpaceX's daring reusable-rocket test last week came up just short because of an issue with a "throttle valve," company founder and CEO Elon Musk said.

"Cause of hard rocket landing confirmed as due to slower than expected throttle valve response. Next attempt in 2 months," he tweeted Saturday (April 18). (SpaceX will try the drone-ship landing again during the next Dragon cargo launch, which is currently scheduled for June 18.)

Is that with or without the supplies? Seems to me it would kinda suck if they were running low on groceries up there...
 
Sometimes the Interplanetary Magnetic Field points south. When it does, space weather becomes a bigger issue for Earth.

QUIET WITH A CHANCE OF FLARES: For the past 48 hours, solar activity has been very low. Sunspot AR2339 is poised to break the quiet. The behemothsunspot is directly facing Earth, and it has an unstable 'beta-gamma' magnetic field that harbors energy for strong eruptions. NOAA forecasters estimate a 30% chance of M-class solar flares and a 5% chance of X-flares on May 11th. Solar flare alerts: text, voice

AURORAS SIGHTED, MORE TO COME: Mother's Day in Canada began with a sunrise display of Northern Lights. On Sunday, May 10th, Harlan Thomas photographed a green band above the rosy twilight east of Calgary:



Shortly before Thomas took the picture, the interplanetary magnetic field (IMF) near Earth tipped south. This opened a crack in our planet's magnetosphere. Solar wind poured in to fuel the display.

More auroras are in the offing. NOAA forecasters estimate a 45% chance of polar geomagnetic storms on May 11th when a co-rotating interaction region (CIR) is expected to hit Earth's magnetic field. CIRs are transition zones between fast- and slow-moving solar wind streams. Solar wind plasma piles up in these regions, producing density gradients and shock waves that do a good job of sparking auroras.
