La crescita di un germoglio di pianta da cotone avvenuta direttamente sulla superficie lunare.
L'esperimento risiede all'interno del lander cinese Chang'e 4, chiuso in una camera stagna, rifornita di ossigeno e acqua necessaria alla crescita della pianta stessa. Inoltre, sono presenti esemplari di Saccharomyces cervisiae e Drosophila melanogaster, nomi scientifici del comune lievito e del moscerino della frutta.
Perché proprio questi organismi?
Perché il lievito metabolizza le sostanze di scarto, essendo per definizione, dei saprofiti, ovvero che metabolizzano gli scarti derivati dai moscerini rendendo disponibili altre sostanze nutritizie. Insomma, un mini ecosistema per il sostentamento dei germogli di cotone.
Il fine ultimo dell'esperimento è comprendere se, con tali escursioni termiche, - 137C durante la notte e +100C durante il giorno, l'ecosistema si mantiene stabile. Senza contare che la camera che lo contiene non possiede una schermatura e si potranno studiare nel dettaglio l'effetto delle radiazioni ionizzanti sul DNA dei microorganismi sopracitati e comprendere quali alterazioni comportano una lunga esposizione ai raggi cosmici.
THIS WENT TO SPACE!
The Intermediate Experimental Vehicle, IXV, reached an altitude of 412km on February 11th 2015. It was designed to test atmospheric re-entry technologies and reached a top speed of 7.5km / sec - that's 27,000kph! - in re-entry.
The air resistance at that speed heated the thermal tiles up to immense temperatures, over 1500 degrees C on the outside, while their incredible insulating capacity kept the instruments inside the craft relatively cool.
The craft deployed a parachute and splashed down in the Pacific Ocean, where the heat of the tiles boiled the sea water as they cooled; the salt deposits are still present on the tiles.
It's on display in Turin Airport departure hall.
"Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there--on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There"
Carl Sagan, 1994
Ariane 6 - The new future
The Arianespace Group production sites have already initiated the production of 3 Ariane 6 launchers!
The exit of the factory of these florets of the aerospace industry will take place as of 2020
🚀 SpaceX est-il devenu imbattable dans la conquête spatiale ?
🌔 Le groupe d’Elon Musk a effectué 21 lancements en 2018, soit deux fois plus qu’Arianespace. Si le champion américain semble désormais hors de portée, un examen plus fin montre que l’Europe n’est pas totalement larguée.

HAPPY NEW YEAR! BIENVENUE 2019
Let's start this year with a countdown (or in this case a count-up) 2018 was another year of travel for me as I slowly add countries/territories with the aim of visiting as much countries as much as my knees allow me in this lifetime.
Territory/country #28 FRENCH GUIANA 🇬🇫 This is an overseas territory of France in South America. A former colonial prison for France's outcasts and slaves, sitting in the lush outskirts of the Amazon basin, it is now a paradise where its people enjoy the perks of French citizenship and a hub for France's Space Exploration programs.
• Log Entry: Day 1
Everything's ready. Now it's time to double-check the most important things before leaving: documents✔, purse✔, flight tickets✔, extreme mosquitos repellent✔.
Today I'm flying from Turin to Paris where I'm going to spend a night, so today you're going to follow my adventure through France's capital, trying not to lose myself and attempting at speaking French. Tomorrow I'm going to meet Guillaume, who will be the director of my video reportage, and someone else from Ariane's communication office whom I still don't know. Together we'll take the flight for Kourou very early and it's going to last for 10 hours during which you won't hear from me. But this is another story that I'll tell you tomorrow. For now this is it.
Don't miss my instagram stories throughout the entire trip!
