Spacex WTF?

People on another board saying this is just ice but it looks to be miles below and it seems to change direction super fast maybe my eyes are messed up


youtu.be...

Right around 17:53 it looks like a piece of trash is heading towards earth then BOOM it goes retard super sonic wtf cause this?

Probably within the rockets slipstream and then it shoots out of the slipstream and gone
Don’t think it’s anything but ice

Flecks of ice don't just float around in space like that. Water ice in a vacuum sublimates away after a while.

These flecks of ice are formed on the cold parts of the rocket, where they have condensed as it goes through the atmosphere, and then they break away as the surfaces warm up.

You will notice just previous to this event, the firing up of the 2nd stage rocket engines after the ejection of the 1st stage engines and fairings. Before the engines are fired up, they are very cold due usually to the liquid oxygen portion of the fuel mix (and also possibly from explosive decompression).

The flecks of ice are essentially travelling with the rocket so they don't appear to move very fast, but as they are not under power like the rocket, they tend to gradually fall behind. When they get close enough to the rocket exhaust, it blasts them away from the rocket rather quickly as demonstrated in the video.

Until the aliens land and reveal themselves properly this is all a waste of time and BS.

It's ok to not know yet for sure what's going on.

In fact, I don't think we would want to know.

Great spot The way it rolls over the engine........................ Would ice cristals / space debris do that? I'm leaning towards white type ufo orb, indeed I think there's another one too just after

Yep, look on the right side picture just after the ice on the left side picture does what you say. You see in the right side picture a chunk of ice do exactly the same thing from a closeup perspective. It's just the camera perspective.

17:58 on the ride side perspective, you see more ice doing exactly the same thing.

Yup space is cold and get your eyes checked yearly...

Just for some clarity....are you talking about the ice flake falling (rolling) off the engine nozzle pic set #1...... or the jettisoned fairing pic set #2..... or neither, in which case I missed it.

#1



#2

They need a camera pointed up on the landing ship that would be GREAT!

Alien UFO’s are now 3 feet long and attack rocket plumes, run for the ocean.

That's a very dubious re-entry, I think they forgot something at home and had to return

Slight Sidebar and re-purposing the title of this thread, but EM related ..... not only does he not care about littering space with more space junk from his rockets....now there’s this:

Taken from and Originally published on Live Science.

'Starman' just zipped past Mars in his rapidly-decaying Tesla Roadster

.....”At this point, if you were to go look at the Roadster, it probably would look pretty different. As Live Science reported in 2018, the harsh solar radiation environment between the planets would probably have wrecked all the exposed organic materials (red paint, rubber tires, leather seats and the like), breaking the carbon bonds that hold them together. And without Earth's protective atmosphere and magnetic shielding, even the robust plastics in the windshield and carbon fiber materials would start to disintegrate. Over the course of decades or centuries, the car should be reduced to its aluminum frame and sturdiest glass parts — assuming none of them get destroyed in impacts with passing space rocks.....”

Thank You soooooo much EM for making some of our solar systems space, a literal Auto-Junk Yard!!! ......(not including the auto-junk yard on the moon)

Butt you probably think that, that is so cooooool.

As if we don’t have enough space debris.

Short answer:
Rocket exhaust pushes it out of the way.


Longer answer:
The returning booster has cut off its main engine, but there are smaller attitude control system (ACS) thrusters that, along with the grid fins, help keep the booster in the correct orientation for the return to Earth. ACS thrusters operate for just short bursts to make micro adjustments of the booster orientation, although each ACS thruster makes multiple, sporadic short bursts

Those little ACS thrusters don't produce a flame; they use pressurized nitrogen gas as a propellant. That nitrogen gas is often almost invisible or barely visible as quick little puffs when the ACS thrusters activate.

So what you are seeing here is likely this: The piece of debris is ice or loose material from stage separation or something. It moves generally along the same path as the booster for a while, although atmospheric drag will cause its path to be slightly different than the booster, and it falls behind the booster. It falls into the path of one of these ACS thrusters activating and the exhaust from that thruster pushes the debris out of the way.


EDIT TO ADD: I also noticed the slight fog that develops right around the grid fins. That could be due to the booster being in a part of the atmosphere that is thick enough for the water vaper to be condensed due to pushing up against the grid fins as they slip through the air. So maybe there is enough of an atmosphere at that point that the booster itself or the grid fins cause turbulence or an eddy that the debris hits.

But I'm more inclined to say the debris was pushed away by the ACS thrusters.

Wait so if they think a short trip in space will result in complete disintegration of most materials than why are they also claiming that planets could be seeded via panspermia? Surely any microorganism would be dust long before plastics and other composites broke down.

I wonder if I'm missing something here or if they are actually holding contradictory beliefs.

Maybe the radiation levels in space (in our solar system absent a storm at least) aren't necessarily too bad?

I'd definitely like to know more about that.

If the microbes are alive (or even just dormant) deep inside a relatively large space rock, and that space rock enters Earth's atmosphere, not all of the rock might be obliterated and some relatively larger pieces might survive to the ground. The life that was inside that rock might have been insulated enough from reentry by the rock around it.

There are reports that microbes have been found on earth that might have been dormant for millions of years under the surface before they were reanimated upon being brought up to the surface. So it's possible that microbes might be able to lie dormant in an asteroid for millions of years.


Let's say there were microbes on Mars 4 billion years ago when Mars was warmer and wetter. Those microbes might have found their way deep into some bedrock through cracks. Then one day a large asteroid (something the size of the one that some say led to the end of the dinosaurs on Earth) smashes into Mars, breaking large chunks of that microbe-laden bedrock into space.

That rock floats through space for a while with those Mars microbes lying dormant deep inside, until one day it enters earth's atmosphere. Most of it breaks up, but some grapefruit-sized chunks remain. Those fall to the ground where they get rained on, and the dormant microbes inside wake up on their new home planet.

Hmmm since our best bet at surviving in space is by using an EM field as a radiation shield, I wonder if some of these asteroids have magnetic properties capable of providing a little protection?

Encasing ourselves in rock would work...technically. But it wouldn't be very practical.

Seriously though, it's been said that 1 meter of water surrounding a spaceship hull would be adequate shielding -- but that much water (or rock) is very heavy and has a lot of mass.

Water works as shielding because of its high hydrogen content and density. They are working on polyethylene plastic shielding because of its hydrogen content. However, even that plastic shielding would require a thickness of more than 30 cm to provide adequate shielding.

Dude Space is HUGE. Why are you freaking out over one little car? Who gives a damn? Stuff in LEO will eventually burn up on reentry or fall to Earth while that Tesla Roadster will eventually leave the Solar system.

We NEED to move out into the Solar System and eventually the Stars n order to survive as a species in case something happens on Earth.

...while that Tesla Roadster will eventually leave the Solar system.

The roadster is not on a trajectory out of the solar system; it likely will continue in its orbit around the Sun for at least a few billion years.

It's in a solar orbit that lies mostly between the Earth and Mars, bringing it close to Earth's orbit and a little past Mars' orbit, and taking about 18 months to complete each orbit around the Sun.

Although every 18 months it goes past Mars' orbit and comes close to Earth's orbit, the Roadster's slight orbital inclination (tilt) is such that it will likely never impact Mars or Earth.
