ESA Space Science

ESA has selected six new Fellows to pursue their own independent research in space science in 2026. The Research Fellowships in space science represent one of the highlights of the ESA Science programme.

Early career postdoctoral scientists are offered the unique opportunity to carry out advanced research related to the space science areas covered by ESA Science missions at one of three ESA establishments (ESAC, ESTEC or STScI) for a period of up to three years.

The 2026 Research Fellows in space science are, Emma Esparza-Borges, Ekaterina Ilin, Gregor Rihtaršič, Peter Stephenson, Paola I. Tiranti, and Jiří Žák.

Their research spans a broad range of exciting topics in the fields of heliophysics, planetary science, astrophysics, and fundamental physics. For example, they will investigate the nature of dark matter using galaxy cluster collisions, learn how Jupiter’s atmosphere works using the observations of the famous Great Red Spot, and explore the evolutionary pathways of exoplanets. More information about the Fellows and their research can be found here

The European-Chinese Smile mission is due to launch on Tuesday 19 May 2026, at 05:52 CEST / 04:52 BST / 00:52 local time on a European Vega-C rocket.

The European Space Agency Plato mission has successfully completed a series of tough tests under space‑like conditions. With this accomplishment, the spacecraft is on track to lift off in early 2027 and begin its search for terrestrial planets.

The NASA/ESA Hubble Space Telescope looked at a scene it first captured in 1997 in honour of 36th anniversary: a small portion of a star-forming region about 5000 light-years away in the constellation Sagittarius, known as the Trifid Nebula. The image shows changes over incredibly short timescales and instills a sense of awe and wonder about our ever-changing Universe.

Noticeable change on Mars often takes millions of years – but the European Space Agency’s Mars Express has captured a blanket of dark ash creeping across the planet in just decades.

The European Space Agency and the Chinese Academy of Sciences are joining hands to uncover how Earth defends itself against dangerous particles and radiation from the Sun.

It’s the first time we will have images and videos of what happens when this solar wind crashes into our magnetic field. Smile will witness this interaction in action, using four onboard instruments to watch the drama unfold.

Life can only exist as we know it when nestled safe inside this giant magnetic bubble surrounding our planet. By imaging the bubble as a whole for the first time, Smile will help us build up the fundamental understanding that space weather forecasting will ultimately depend on.

What really happens when the Sun’s charged particles slam into Earth’s magnetic shield? 

Smile is about to reveal it for the first time.

This groundbreaking mission will observe Earth’s magnetosphere in X-rays while capturing the northern lights in ultraviolet, offering an entirely new way to see how our planet defends itself from solar storms.

A joint mission between the European Space Agency and the Chinese Academy of Sciences, Smile will launch aboard a Vega-C rocket on 9 April.

Watch the replay of the Smile pre-launch media briefing. The briefing covered key details ahead of the mission’s launch aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. Smile is a joint mission between ESA and the Chinese Academy of Sciences, designed to study how the solar wind interacts with Earth’s magnetic field.

The journey of Juice

Video series covering Juice's journey to Jupiter

Plato, the European Space Agency’s mission to discover Earth-like exoplanets, successfully passed a first round of tests designed to ensure that the spacecraft is fit for launch. As this video shows, the tests consist of vigorously shaking the spacecraft to mimic the powerful jolts and vibrations that Plato will experience during launch.

These so-called ‘vibration tests’, are arranged in three parts. In this clip, we see the phase when the spacecraft, mounted on a ‘quad’ shaker, is jolted up and down (Z axis). In the other two stages, on top a ‘lateral’ shaker, the spacecraft is jiggled back and forth sideways in two perpendicular directions (X and Y axes).

Each test run lasts one minute, during which the frequency of the oscillations is gradually increased from 5 to 100 oscillations per second (hertz). At the higher frequencies we can no longer perceive the movement, but we hear the spacecraft’s internal rumbling caused by the fast shaking. The sound comes in waves, becoming louder when the shaker hits resonance frequencies and makes the spacecraft vibrate more intensely.

The first couple of minutes of a satellite's spaceflight are the toughest, as it sustains the extreme vibration of lift-off. By subjecting the spacecraft with these dramatic stresses in advance of the real launch, engineers ensure that no piece of space hardware will be damaged during launch.

Plato is currently undertaking its tough exams to graduate for launch. After vibration tests, the spacecraft was placed inside ESA’s acoustic test chamber and blasted by deafening sound similar to what it will experience during lift-off. Also this test went as expected.

Next, engineers will move the spacecraft to the Large Space Simulator – Europe’s largest vacuum chamber – to verify that it can withstand the extreme temperatures and emptiness of space.

The mission is expected to be ready for launch by the end of the year. Lift-off on an Ariane 6 is planned in by Ariane Space for January 2027.

About Plato

ESA’s Plato (PLAnetary Transits and Oscillations of stars) will use 26 cameras to study terrestrial exoplanets in orbits up to the habitable zone of Sun-like stars.

Plato's scientific instrumentation, consisting of the cameras and electronic units, is provided through a collaboration between ESA and the Plato Mission Consortium composed of various European research centres, institutes and industries. The spacecraft is being built and assembled by the industrial Plato Core Team led by OHB together with Thales Alenia Space and Beyond Gravity.
