ESA's Solar Orbiter Should Solve Mystery Of Sun's Outermost Atmosphere
ESA's Solar Orbiter mission will face the Sun from within the orbit of Mercury at its closest ... More approach. The European Space Agency's Solar Orbiter mission recently stunned the world with the first-ever full images of our Sun's South pole, proving that this was going to be a mission like no other. Using an orbital gravity assist from the planet Venus, the Solar Orbiter mission spacecraft was able to maneuver into an orbit that has taken it to an angle 17 degrees below the Sun's equator. Over the coming years, the spacecraft will tilt its orbit even further, so the best views are yet to come, says ESA. The 1.2-billion-euro Solar Orbiter mission, with NASA participation, should finally help us understand the origin of the Sun's solar winds as well as our understanding of the Sun's poles. And arguably most importantly, it should solve the puzzle of why our star's outermost atmosphere, or corona, is heated to millions of degrees Kelvin and is thus so much hotter than the Sun's own surface. By contrast, our Sun's visible photosphere, or surface, averages only 5,500 degrees K. With Solar Orbiter, we are clearly seeing energy releases on the nano-flare scale, Daniel Mueller, a solar physicist and ESA project scientist for both ESA's SOHO and Solar Orbiter missions to the Sun, tells me in his office in The Netherlands. But the question is, would these nano-flares continue like that infinitely, or is there a certain lower limit to the production of these nano-flares, Mueller wonders. The puzzle is whether these nano-flares are enough to heat up the Sun's corona to the temperatures with which it is routinely measured. A Unique View Launched in 2020, from its highly elliptical orbit just inside Mercury's perihelion, the closest point in our innermost planet's solar orbit, the ESA spacecraft offers the best views yet of our own yellow dwarf star. We can see on scales down to about 200 kilometers on the Sun, which shows us a lot of dynamics of our star, says Mueller. And thanks to its newly tilted orbit around the Sun, the European Space Agency-led Solar Orbiter spacecraft is the first to image the Sun's poles from outside the ecliptic plane (the imaginary geometric plane in which our Earth orbits the Sun), says ESA. We observed the Sun's North pole at the end of this past April, says Mueller. But we passed the Southern pole first and then the Northern pole six weeks later, he says. At the moment, as seen from Earth, the Solar Orbiter is almost behind the Sun, so the data downlink has slowed to a trickle. But by early October, Mueller expects to have downloaded all the data from Solar Orbiter's Spring polar observations of the Sun. And within a matter of two to three months after the data is on the ground, the first scientific results will have been written up and submitted to journals for publication, says Mueller. These observations are also key to understanding the Sun's magnetic field and why it flips roughly every 11 years, coinciding with a peak in solar activity, says ESA. The spacecraft's instruments show that the Sun's South pole is a bit of a magnetic mess now, with both North and South polarity magnetic fields present, ESA notes. Ready To Flip Right now, there is not a clear dominant magnetic polarity, but a mix of the two, says Mueller. And that is exactly what you would expect to find during the maximum of the Sun's activity cycle, when the magnetic field is about to flip, he says. The real applications are for space weather predictions. Case in point, better space weather forecasting may have saved many of Elon Musk's 523 Starlink satellites that reentered Earth's atmosphere between 2020 and 2024. This period coincides with the rising phase of solar cycle 25, which has shown itself to be more intense than the previous solar cycle, the authors of a 2025 paper appearing in the journal Frontiers in Astronomy and Space Sciences write. Our results indisputably show that satellites reenter faster with higher geomagnetic activity, the authors note. There was a big solar storm that caused the earth's upper Earth atmosphere to expand, so, the satellites experienced more drag, and therefore didn't make it to orbit, says Mueller. One option may have been simply to hold off on launches until this increased period of solar activity enabled a less risky geomagnetic environment in Earth's upper atmosphere. The hope is that the Solar Orbiter mission and other missions like it will lead to better and more reliable space weather predictions that could potentially save hundreds of millions of dollars in the commercial satellite industry. Solar Orbiter should do its share in solving both pure solar physics conundrums as well as in more practical applications like space weather. The good news is that the spacecraft still has plenty of fuel left. Our current funding goes until the end of 2026, but because we had a picture-perfect launch provided by United Launch Alliance and NASA, we saved a lot of fuel, says Mueller. So, the onboard fuel reserves are so large that we can keep going for a long time, he says.

The European Space Agency and Dassault Aviation paving the way for potential collaborations
PRESS RELEASE June 20, 2025 The European Space Agency and Dassault Aviation paving the way for potential collaborations ESA and Dassault Aviation have identified a mutual interest in developing a closer relationship to commonly foster technology development in areas such as LEO destinations and particularly around orbital vehicules. The European Space Agency (ESA) has signed a Letter of Intent (LoI) with Dassault Aviation, a French civilian and military aircraft manufacturer recognized worldwide for its excellence, underlying their common interest to develop a closer relationship. ESA, with its ambitious strategy for space exploration, Explore2040, is seeking innovative solutions for capabilities development to reach and return from Low Earth Orbit (LEO), Moon and Mars, and supports the advancement of selected critical enabling technologies to be used and demonstrated in particular in LEO, such as hypervelocity re-entry. Dassault Aviation, also a leader in aerospace engineering, is developing its space activities with a focus on the design of a reusable spaceplane based on lifting bodies shapes that bridge aeronautical and space technologies. Their interest in automated LEO platforms suitable for commercial and institutional markets, led them to develop a vehicle concept called ' Véhicule Orbital Réutilisable de Transport et d'Exploration (VORTEX) ', designed for research in space, transport of cargo to and from space stations, and a range of in-orbit services. This project is based on a considerable expertise in spaceplanes having participated in numerous programmes like Hermes, NASA X-38 Crew Rescue vehicle, ESA Intermediate eXperimental Vehicle (IXV) demonstrator, and Airborne Reusable Hypersonic Experimental Vehicle (VEHRA) concepts. ' Dassault Aviation's decades of expertise in aeronautical and space systems, perfectly position them to pioneer critical space technologies ', said Josef Aschbacher, Director General of the European Space Agency. ' With VORTEX, Dassault is contributing to strengthening European capacities and securing sovereign access to space in a strongly growing and competitive space sector. We look forward to combining our expertise and working hand-in-hand for a stronger Europe in space.' ' Our Vortex roadmap aims to strengthen Europe's essential sovereign capabilities and meet the new challenges of the space economy. This letter of intent is a perfect recognition of the complementary expertise of the European Space Agency and Dassault Aviation in the development of critical technologies and innovative space solutions, ' declared Eric Trappier, Chaiman and CEO of Dassault Aviation. As such, the signatories of the LoI, have identified a mutual interest in developing a closer relationship with the potential to commonly derisking critical technologies as well as to further explore the potential for collaboration in areas such as LEO destinations and particularly around orbital vehicules. As such, both foresee an interest to cooperate on a scaled down suborbital version of VORTEX, serving as a testbed, with a focus on, but not limited to: Designing, testing and qualifying key technologies and components. New materials and integration processes. Assessing the feasibility to include future payloads in case of the integration of a dedicated bay on the end-product. This joint work will be based on exchanging relevant information and conducting studies or preparatory activities, to help establish respective roles and responsibilities in the realisation of potential joint activities, leveraging on each side's capabilities. ' Europe benefits from a wide range of diverse and complementary skills. Enlarging the European industrial base is key for new opportunities arising in Space Exploration, aiming at more autonomy,' said Daniel Neuenschwander, Director of Human and Robotic Exploration at ESA. About the European Space Agency The European Space Agency (ESA) provides Europe's gateway to is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe's space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.
