Meidän toiminta?

Se portin sulkeminen ja lapun jättäminen luukulle. Menee filosofiseks, mutta omission ja aktin raja on hiuksen hieno. Auttamatta jättäminen on omissio, portin sulkeminen ja lapun luukulle jättäminen taas on akti. Tässä tilanteessa se ja sama kummalla mennään.

Tässä on ajateltava itsekkäästi.

Itsekkäästihän tässä ollaan ajateltu kaiken aikaa. Sisäpoliittinen kuohunta on Suomen valtion omien intressien vastaista.

Meidän ei tule pelata samaa peliä.

Ollaan kuule pelattu samaa peliä jo siitä lähtien kun aiheesta alettiin puhumaan mediassa. Ainoa tapa jolla me oltais vältetty pelin pelaaminen, olis se että oltais otettu kaikki pakolaiset sisään ilman mitään mutinaa, koska ei muutama tuhatkaan pakolaista oo oikeesti tunnu missään pakolaiskriisin jälkeen. Tosin aivan varmasti Persut ja muut rasistit olis tästä silti vetäneet herneen nenään, jolloinka vaikutusyritys sais silloinkin jotakin aikaan.

Epäiletkö etteikö niin voisi tapahtua? Kun nyt vielä erikseen otit ihan itse esillle sen mitä Puolan rajoilla tapahtui?

Väännetään nyt sit rautalangasta: Lähes kaikki jotka sinne Puolan rajalle meni, meni itse omatoimisesti ajatellen että heitä odottaa parempi elämä Puolassa. Pakkokeinot tuli käyttöön vasta kun pakolaiset koitti pettyneinä kääntyä takaisin. Tilanne on siis nyt erilainen, koska Venäjä joutuu käyttämään pakkokeinoja jo tässä vaiheessa ihmisten saamiseen sinne rajalle. Ihmismassojen saaminen jonnekkin on paljon helpompaa jos ne menee sinne itse. Kovin veikkaan että Venäjällä olevat pakolaiset ovat kuulleet Puolan tapahtumista eivätkä halua samaan tilanteeseen.

Mars rovers are expensive as fuck, their capabilities are basic at most when compared to humans, and even then they aren't built to withstand snow and ice. Research institutes don't send people to the ass end of the world just because they can.

Remote sensing is great, but a considerable portion of the work done in the Antarctic is to benchmark the data we get from Earth observation satellites so we can develop those capabilities further. And even then, there's only so much that can be done with satellites.

So all the environmental science done there is somehow not good for the environment?

While there's definitely already too much tourists, about 90% of people visiting inland Antarctica are still scientists and their support staff.

Is there too much tourism in Antarctica? Yes.

Is this it? No.

If you think that the research institute operating the airstrip wants to have a tourist resort next door to their Antarctic research base, I do not know what to tell you.

Jos meidän toiminnan seurauksena jengiä kuolee rajalle, koituu asiasta sisäpoliittista kuohuntaa ja Venäjä on saavuttanut tavoitteensa.

Paras tapa omasta mielestä olis ottaa nämä nyt vielä sisään etteivät kuole, jonka jälkeen ison profiilin lausunto että nyt laitetaan lappu luukulle. Näin sais vastuun tulevista rajalle jäätyvistä siirrettyä mahollisimman näkyvästi Venäjän harteille ja sisäpoliittiset vaikutukset minimoitua.

Tää on 100% PR-tappelu. Optiikat on kaikki kaikessa ja omien käsien tahtaaminen viattomien verellä on iso tyylimoka.

Ps. Tyylikästä ryssittelyä. Se on aina kiva tietää keskustelevansa aikuisten ihmisten kesken.

Edit: Niin joo ja koska ne joutuu nyt jo pakottamasn väkee rajalle, on syytä olettaa että suuri osa pakolaisista on tietosia siitä mitä Puolan rajalla tapahtu. Pakolaisten massamuilutus tuhansittain olis semmonen logistinen operaatio että saas nähdä olisko ees Venäjällä kuinka käytännöllistä.

"The most important thing is the environmental benefits we can achieve by using large and modern aircraft of this type for Troll," Ms Brekke said.

"This can help to reduce total emissions and the environmental footprint in Antarctica.”

You wouldn't have needed to even read the article since OP copied this part into the post. Please, read before commenting.

No problem, everyone else is too.

Summer is the time of the year with endless days at high latitudes. That's when the rule "don't eat when the sun is up" becomes a problem.

I have my doubts about that stealth. If it were just the tungsten rod by itself, it could well be coated in black, but the impulse needed to drop a massive projectile out of an orbit (and furthermore into a trajectory that impacts at the target) necessitates a relatively hefty maneuvering unit and that has to radiate heat to be kept operational. Cheaping out on the propulsion could be very costly because a failure in the middle of the deorbit burn would result in the rod coming down in a place you don't want it to.

The only way to hide it would be with decoys, which are already used by ICBM's. Unlike ICBM's, an orbital platform would need those decoys well before it's used because there's no terrain to hide in. A ballistic missile sub is very hard to track, satellites, not so much.

About countermeasures: Becuse the rod can't move by itself, it's stuck on a fixed trajectory after the propulsion stage is discarded. This makes it an easy target for an interceptor missile. You already know where to look so the stealthy rod isn't that hard to find, and then you just have to collide with it. And because the rod is coming down from MEO at the very least, you have ample time to do all this. An impact at such speeds would disintigrate anything and the rod isn't an exception. At the very least it would fracture into multiple less aerodynamic pieces that do much less damage than the sum of their parts.

Gravity is not your friend. Getting stuff into LEO is still expensive af. A kinetic projectile dropped from space might have the same energy as a nuke, but it's still going to be a lot more expensive. Additionally, you don't have options on how that energy is released. It's going into the ground and that's that. A nuke (or any other explosive device for that matter) on the other hand can be detonated at a chosen altitude, or as a bunker buster if that's what you want.

The heavier the object, the more it's going to take to push it out of that orbit. If your weapon system is in LEO, you can realistically only drop a rod on a small envelope along the future trajectory of the weapon system. Polar orbits would have the best coverage, but fly over a target outside of polar regions only twice a day. In order to get a wider range of firing solutions, the projectile needs considerable deltaV for orbital changes. And again, gravity fucks you over here because deep within Earth's gravity well, changing the orbit of a massive tungsten rod takes a lot of fuel. Higher up these deltaV costs wouldn't be as prohibitive and you'd have more options for using the weapon, but that would increase the time from launch to impact into the regieme of hours, way too slow for anything.

The best solution would be to have a huge amount of rods in different orbits (akin to the spacejunk that is Starlink) to maximize the chances of at least one being able to fire on a target at any given place at any given time, but because those rods are still heavy af, such a plan is completely unfeasable.

Rods from gods will never happen, at least not around Earth.

Looks like you indeed did! Nice catch!

Fluctus is a cloud formation that requires quite specific circumstances to occur. The physical phenomenon itself (Kelvin-Helmholtz instability) is quite common, occuring at the border of two layers of fluids moving in different directions and/or speeds. The most common instance would be the waves you see on water.

But to be visible in a cloud like this, there not only needs to be a cloud at that same place, but it has to also occur perpendicularly to the observer so you can see it clearly from the side like this. Because of these three factors rarely happening all at once, as well as the short lifespan of the formation (the waves usually crash within minutes), it is widely considered a rarity.

Safe to say, I was very stoked when I saw one lining up for this shot.

It was pretty funny seeing these two goofing off and then hearing the final boarding call for that particular flight asking the last passenger to come to the gate posthaste.

Here's a Finnair A350 taxiing to the runway on it's trip from Helsinki to Singapore at 01:30 last night.

The cloud itself was mostly Altocumulus stratiformis with some lenticular elements embedded. This was in southern Finland last December.

I increased saturation a bit and adjusted the colour temperature in post to filter out most of the overbearing yellow of the sunlight. The original picture:
