Yes I understood ... but still the title can be confusing ...

I agree with your example BUT when we talk about human technology (different therefore from biology where man is only a spectator ... or destroyer but that's not the debate) and we say "the plus XXX du monde "the performances of the past should be taken into account because man is the creator of technology more than of biology ... no? Am I getting lost or what? : Mrgreen:

In short, otherwise the video is interesting especially the telemetry speed and vertical landing 2 boosters! Looks like pictures of a SF movie! Synchro and more! Waaaw !! : Shock:

It starts here:



In this regard how do the boosters get in the right position after their separation? By friction?

Coming soon:



I love the precision of the "prediction area" : Cheesy:

It is done : Mrgreen:
The Chinese space station Tiangong-1 was finally completely destroyed when it returned to the atmosphere Monday to 0h15 GMT over the central part of the South Pacific. https://www.lci.fr/sciences/crash-de-la ... 76416.html

A video of synthesis which explains the future collision between our galaxy and the galaxy of Andromeda in 4 to 5 billions of years:
https://sciencepost.fr/2018/07/la-voie- ... d-dannees/

Andromed being itself the result of a collision of galaxies 3 billion years ago:

The Andromeda spiral galaxy was structured less than 3 billion years ago, following a major collision between two galaxies. This is in any case what reveals a recent study based on computer simulations. Our cosmic neighbor would be younger than our planet.

The Paris Observatory has made simulations a little more precise it seems to me https://www.obspm.fr/la-formation-de-la-galaxie.html



France culture dedicated a program https://www.franceculture.fr/emissions/ ... -mars-2018

Andromeda is heading towards us at 120 km / second.

The views of Ceres in low orbit

By Joel Ignasse the 05.07.2018 Science and Future

The Dawn probe orbiting the dwarf planet maneuvered down to 35 kilometers from the surface of Ceres. The images she captures are the most detailed ever taken.

"It's a gift from nature": a photographer manages to combine lightning, Mars and the lunar eclipse in a single shot

Maxime Verrier was tracking down a thunderstorm Friday when he captured this impressive photo of the longest lunar eclipse of the 21st century.

Image

Some have not seen it at all, because of the clouds. But Maxence Verrier, he managed to photograph the longest total lunar eclipse, Friday July 27. And the bad weather has not served its cliché. We see lightning alongside the red moon as well as Mars, which was particularly visible that night. For Maxence, who shares the story of his stalking in the form of a web series, it is "the photo of a lifetime". Franceinfo questioned this storm tracker on this remarkable image, taken in Haute-Loire.

Franceinfo: Under what conditions did you make this shot? Did you hope to photograph the eclipse?

Maxence Verrier: I did not even imagine taking this picture! We expected to be able to photograph the eclipse, but from 18 hours a thick cloud cover settled in Rhône-Alpes. Me, I am a thunder tracker, in my free time. And as they announced a stormy situation in the evening, I took all my equipment and I left in a hunt that lasted a few 200 kilometers and hours. I finally arrived at Sainte-Sigolène and came across a thunderstorm that had originated on the side of Puy-en-Velay and slid quickly to Valencia. Passing over the Pilat massif, he freed himself from his electric activity, causing many lightning strikes, powerful enough

I had an incredible chance because the sky was clear to discover the orange moon and Mars at his side. When I saw this picture coming out of the back of the camera case, I was stunned. It's the picture of a life. I am quite dazzled by this beautiful gift of nature.

What does the storm add to this picture of the eclipse?

I think of the eclipse photos, we've all seen thousands. But the power of the storm and the energy it unleashes next to this beautiful spectacle of the stars brings us back to our state in relation to the universe and the world. We are really nothing, we are really slab. It made me feel infinitely small. Many things can be done as human beings, but it is nothing compared to the spectacle of nature. That's indescribable.

How is a thunderstorm prepared?

The first tool is the weather. This allows us to anticipate storm prospects and to hunt down. A target is set, even if the meteto remains an inexact science. Then, it is important to have geographical knowledge of the areas we survey, it allows us to know which place will give us a good point of view. And then there is the photographic equipment: I leave with three tripods and three cameras. It is tropicalized material [protected from moisture by specific materials] because our devices are usually soaked after a shot.

We can leave at ten o'clock in the morning and return at two o'clock in the morning the next day, depending on where we are tracking. To tell the truth, 200 kilometers for a tracking, it is not much thing, it is even very little!

The Parker Solar Probe mission will touch the Sun

The solar probe Parker, which was launched on August 12 by NASA, will plunge this fall into the solar corona to explore its mysteries.


(...)

over the next seven years, the probe will turn 23 once around the Sun as it gets closer and closer, eventually crossing the solar corona, only about 6,2 millions of kilometers from the surface of the star. Either seven times closer than the German Helios 2 probe, which holds the record since 1976.

The Parker probe aims to answer some of the big questions about the Sun, such as how its crown is heated to millions of degrees while its surface remains relatively cold (about 5800 Kelvin). The spacecraft will also visit the area where the solar wind forms. This stream of energetic charged particles that escapes from the Sun can reach 800 kilometers per second. When the solar wind hits the Earth's atmosphere, it gives birth to beautiful northern lights, but can also disrupt satellite communication and navigation systems. (...)
