Join us live for a star-studded event this Thursday, as scientists working on ESA’s Hera mission for planetary defence release the mission’s first scientific observations beyond the Earth-Moon system, following its imminent flyby of Mars.
On 12 March 2025 ESA’s Hera mission comes to within 5000 km of the surface of the red planet and 300 km of Mars’s more distant and enigmatic moon Deimos. During this flyby Hera is performing observations of both Mars and the city-sized Deimos.
Hera then needs to swing its High Gain Antenna back to Earth to transmit its data home. The next day, on Thursday 13 March, these images will be premiered by Hera’s science team from ESA’s ESOC mission control centre in Darmstadt, Germany, explaining what they reveal, during our public webcast starting at 11:50 CET.
The team are being joined by ESA astronaut Alexander Gerst and renowned science fiction writer Andy Weir, author of The Martian and Project Hail Mary, as well as a surprise special guest!

Telescopul spațial James Webb are alte obiective importante: descoperirea de asteroizi periculoși, așa cum a fost cel din Chelyabinsk (2013), care a provocat daune mari deși avea doar câțiva zeci de metri. Webb a identificat recent peste 100 de asteroizi noi cu diametrul sub 100 m, contribuind astfel la monitorizarea obiectelor spațiale riscante.
Tot James Webb a captat recent un fenomen astronomic unic: un quasar îndepărtat (11 miliarde de ani-lumină) a cărui lumină trece pe lângă două galaxii intermediare, fenomen numit „zigzag-ul lui Einstein”. Analizând acest fenomen, cercetătorii speră să înțeleagă mai bine energia întunecată și expansiunea universului.
Separat de James Webb, NASA investighează posibilitatea vieții extraterestre pe satelitul Europa al lui Jupiter. Europa are un ocean uriaș sub gheață, unde izvoarele hidrotermale ar putea susține forme primitive de viață bacteriană. Cercetările viitoare ale NASA vor analiza aceste coloane de apă pentru eventuale semne ale vieții microbiene.”
How do we know the Earth isn’t flat? For thousands of years people have known the Earth is round. Ancient civilizations used the stars and shadows to figure it out. Mariners confirmed it by sailing around the globe. And when the space age began, we saw it with our own eyes — the Earth is round!
A NASA scientist explains how we’ve known for centuries that our planet is a sphere.
SpaceX and NASA teams stood down on the March 10, 2025, launch attempt for SPHEREx and PUNCH. We will create a new YouTube live event when the updated date and time when they are available.

Ever wondered how astronauts prepare for the weightlessness of space? In Bordeaux, France, our astronauts train for microgravity using parabolic flights! These special flights create brief periods of zero gravity, mimicking the conditions of space.
By performing a series of steep climbs and descents, the plane allows astronauts to experience intense 2G forces before entering a 22-second weightless phase! This crucial training helps future astronauts adapt to moving, working, and even jumping in zero gravity.
Join us as we follow Rosemary Coogan, Sławosz Uznański-Wiśniewski, and John McFall on their parabolic flight training.

Inside is the very first metal 3D-printed object made aboard the International Space Station!
Scientists will now compare the object with reference prints made on Earth to study how microgravity affects 3D metal printing.
One of our goals for future space development is to create a circular space economy, recycling materials in orbit for better resource use. In the future, we could repurpose old satellite parts into new tools and structures, reducing the need to launch everything from Earth.
A 3D printer in space would let astronauts print what they need, when they need it.
Our metal 3D printer was developed by @airbus_space and its partners.

00:00:00 – Apa ar avea informație? Un mit sau realitate? 00:00:55 – ADN-ul diluat și presupusa lui memorie 00:01:53 – Cercetătorul Luc Montagnier și ipoteza sa 00:02:50 – Dilutii succesive și agitația în homeopatie 00:03:47 – Doar apă, dar cu informație? Experimentul ciudat 00:04:45 – Molecula de apă și structura sa reală 00:05:45 – Organizarea apei și efectele posibile 00:06:41 – Argumentele pro și contra memoriei apei 00:07:39 – Transferul informației genetice prin apă? 00:08:36 – Poezie sau știință? Ipoteza fascinantă 00:09:38 – Dilutii extreme și efectele asupra ADN-ului 00:10:38 – Inducția magnetică și curenții electrici 00:11:35 – Interacțiunea moleculelor de apă și ADN 00:12:33 – Persistența informației după eliminarea ADN-ului 00:13:27 – Variabilele experimentului și măsurătorile 00:14:24 – PCR-ul și reconstruirea ADN-ului diluat 00:15:23 – Informația genetică transmisă prin apă? 00:16:21 – Conexiuni între experimente și laboratoare 00:17:22 – Ce demonstrează rezultatele experimentului? 00:18:18 – Concluzii: există sau nu memoria apei?
algoritm:”Memoria apei reprezintă o ipoteză controversată, potrivit căreia apa, chiar și după diluții extreme, ar reține o amprentă electromagnetică a substanțelor dizolvate. Această apă informată a fost susținută inițial de Jacques Benveniste, care a observat reacții alergice la anticorpi într-o soluție unde, statistic, nu mai exista substanța inițială. Ulterior, Luc Montagnier, laureat Nobel pentru descoperirea virusului HIV, a realizat un experimentul apei, încercând să demonstreze că, după ce ADN în apă este scos, ar rămâne totuși informație genetică transmisibilă la distanță printr-un câmp magnetic variabil. Astfel, PCR ar produce un cod genetic complet, în absența fizică a segmentelor ADN, dacă enzima polimerază ar fi influențată de o memorie spirituală a apei.
Conform susținătorilor, această amprentă energetică s-ar păstra prin agitare, transformând structura moleculară a apei și capacitatea ei de a înmagazina date. Ei compară procedura cu scufundarea unui obiect, după care apa pură ar reține urmele sale, precum mii de nucleotide ce compun un cod genetic invizibil. În homeopatie, ideea că apa memoriei ar putea explica efectele remediilor ultradiluate a generat numeroase dezbateri, mulți considerând-o doar pseudoștiință, lipsită de mecanisme fizice cuantificabile. Totuși, unii cercetători explorează posibilitatea ca apa să funcționeze ca suport pentru informație, evocând analogii cu fenomene cuantice greu de măsurat.
În concluzie, memorie apei rămâne un subiect aprig disputat, care provoacă întrebări despre limitele cunoașterii și deschiderea către idei noi. Deși conceptul de apă informată pare fascinant, el nu se bucură de recunoaștere generală. De la primele experiențe ale lui Jacques Benveniste până la eforturile lui Montagnier, niciun studiu nu a convins comunitatea științifică de existența reală a acestei proprietăți. Rămâne de văzut dacă viitoarele cercetări vor oferi indicii concludente, ori dacă fenomenul va fi respins definitiv drept pseudoștiință. Pentru moment, apa pură își păstrează misterele, iar ipoteza unei amprente genetice active, detectabile prin instrumente obișnuite, continuă să fascineze, dar și să stârnească numeroase semne de întrebare.”

It turns out water is great at blocking radiation. But using water as a protection system has its challenges.
A team from the Polymer Chemistry and Biomaterials Group (PBM) at Ghent University in Belgium is looking into a new option: superabsorbent polymers (SAPs).
These materials might be safer and more effective than water alone.
SAPs can soak up hundreds of times their weight in liquid, similar to those “grow monster” toys that expand in water. When swollen with liquid, they’re called “hydrogels.”

For years, scientists believed Mars got its red color from hematite, a type of rust that forms in dry conditions. But a new study suggests something surprising—ferrihydrite, a different kind of rust that forms in cool liquid water!
This discovery could mean Mars was once much wetter than we thought—maybe even habitable. And the best part? Our Rosalind Franklin rover will soon analyse Martian soil up close to uncover even more secrets.
