In 2028, ESA will launch its most ambitious exploration mission to search for past and present signs of life on Mars.
Enjoy the ExoMars Rosalind Franklin mission in minute detail – everything down to the colour and size of the wires, sticky tape and scratches. The spacecraft, the rover and martian landscapes are as true to reality as possible for a simulation. The visuals show the spacecraft structural engineering with a faithful robotic appearance. The martian landscape has been simulated with meticulous realism.
The story begins with the rover exploring the surface of the Red Planet. There is science to be done. Join the adventure.
This trailer provides a first taste for the most accurate animation series made so far of a Mars mission.
ESA’s Rosalind Franklin rover has unique scientific potential to search for evidence of past life on Mars thanks to its drill and scientific instruments. It will be the first rover to reach a depth of up to two metres deep below the surface, acquiring samples that have been protected from surface radiation and extreme temperatures. The drill will retrieve soils from ancient parts of Mars and analyse them in situ with its onboard laboratory.
The mission will also serve to demonstrate key technologies that Europe needs to master for future planetary exploration missions. This includes the capability to land safely on a planet, to move autonomously on the surface, and to perform drilling and sample processing and analysis automatically. The rover will use novel driving techniques including wheel-walking to overcome difficult terrains, as well as autonomous navigation software.
We are Europe’s gateway to space. Our mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world. Check out https://www.esa.int/ to get up to speed on everything space related.
NASA’s mission is to explore the unknown in air and space, innovate for the benefit of humanity, and inspire the world through discovery. NASA showed the world that anything is possible in 2023.
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth’s surface. Ground that has been frozen for thousands of years, called permafrost, is thawing – adding to the climate crisis and causing serious issues for local communities.
Scientists estimate that the world’s permafrost holds almost double the amount of carbon that is currently in the atmosphere. When permafrost warms and thaws, it releases methane and carbon dioxide, adding these greenhouse gases to the atmosphere and making global warming even worse.
While permafrost cannot be directly observed from space, a lot of different types of satellite data, along with ground measurements and modelling, allow scientists to paint a picture of permafrost ground conditions.

From aerodynamics to space launches, the power of air is all around us! Join Phil as he explores different scientific principles of air and how humans have learned to manipulate it for the greater good!
Have you ever done a science experiment and wondered “What would this be like if it were HUGE?” Welcome to Science Max, the exciting series that turbocharges all the science experiments you’ve done at home.
0:00 – Paper airplane – Start by learning how to fold the paper airplane that won the long-distance record. Then Phil tries to make a giant paper airplane to see if it will still fly. Turns out, it’s way harder than you’d think. Plus, terminal velocity and indoor tornadoes!
20:27 – Hot Air Balloon – Hot and Cold. A home-made hot air balloon gets turned into a giant floating monstrosity! Plus: dry ice, the coldest temperature possible and Phil wears a suit of blubber and gets into a tub of ice water.
41:25 – Air Surfing – Air is a fluid, just like water. That means you can surf it if you make a tumblewing. Phil explores lots of different methods of flight all while maxxing out the tumblewing.

🚩 Alfonso VI’s steady expansion and incorporation of Taifas into his realm provoked a reaction from the Almoravids. Commanded by Yusuf ibn Tashfin, the Almoravid army met Alfonso force near Badajos. A victory for the Christians would break the last significant Muslim resistance and enable complete conquest of Iberia. A victory for the Muslims would stop and reverse the Reconquista.

As we look ahead to long-term space missions, one of the big challenges is figuring out how to provide healthy and sustainable food for astronauts. To tackle this, ESA supported two research teams to investigate the possibility of cultivating meat in space.

România se află la un punct de cotitură în ceea ce privește adoptarea energiei solare. Cu un potențial impresionant de aproximativ 1500MW putere instalată în panouri fotovoltaice, țara noastră explorează noi orizonturi în domeniul energiei regenerabile. În 2022, energia solară a contribuit cu aproape două procente la energia totală livrată în rețea, un pas semnificativ spre un viitor mai verde. Acest articol oferă o privire detaliată asupra situației actuale și potențialului energiei solare în România. Explorăm eficiența panourilor solare, care ating în medie 18%, și discutăm despre provocările și oportunitățile sectorului, inclusiv aspectele legate de infrastructură, reglementare și conștientizare publică. În contextul global, energia solară este într-o expansiune rapidă. La nivel mondial, capacitatea solară instalată a depășit 1 Terawatt la începutul anului 2022, cu o creștere impresionantă de 25% față de anul precedent. China și Statele Unite se numără printre liderii acestei creșteri, adăugând capacitate solară semnificativă în ultimii ani. În România, obiectivul național de eliminare treptată a utilizării energiei pe bază de cărbune până în 2032 deschide calea pentru o investiție crescută în surse regenerabile, în special energia solară și eoliană. Așteptăm o creștere considerabilă a capacității fotovoltaice, de la 1,39GW în 2020 la 4,25GW în 2030. Pe fondul creșterii costurilor globale și a provocărilor lanțului de aprovizionare, energia solară rămâne o opțiune cost-eficientă și sustenabilă. Agenția Internațională pentru Energie estimează investiții de 380 de miliarde de dolari în energia solară în 2023, depășind investițiile în industria petrolieră.
An enormous burst of gamma rays was detected by our Integral space telescope, in October 2022. Such disturbances are usually associated with energetic particle events on the Sun but this one was the result of an exploding star almost two billion light-years away.
The blast caused a significant disturbance to our planet’s outer layer, the ionosphere. During the 800 seconds that the gamma rays were impacting, the burst delivered enough energy to activate lightning detectors in India. Instruments in Germany picked up signs that Earth’s ionosphere was disturbed for several hours by the blast.
The blast even triggered instruments generally reserved for studying the immense explosions in the Sun’s atmosphere known as solar flares.
Such an effect has been speculated to be a possible cause of some of the mass extinction events known to have taken place on Earth in the past. But to investigate the idea, we will need a lot more data.

The Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) mission will be the first satellite mission to measure how much carbon dioxide is released into the atmosphere through human activity.
CO2M isn’t just a mission; it’s a crucial step in our commitment to understanding and mitigating climate change. It will offer unprecedented precision in monitoring carbon dioxide emissions from the combustion of fossil fuel at national and regional scales.
Its data will provide the EU with a unique and independent source of information to assess the effectiveness of policy measures and to track their impact towards decarbonising Europe ahead of the next Global Stocktake set to place in 2028.
The video features interviews with Valerie Fernandez, CO2M Mission Project Manager, Yannig Durand, CO2M Payload Manager and Yasjka Meijer, CO2M Mission Scientist.
