Video: 00:12:07 The Making of Juice series takes the viewer behind the scenes of the European space industry, space technology and planetary science communities around ESA’s Jupiter Icy Moons Explorer (Juice) mission. Juice has a state-of-the-art science payload comprising remote sensing, geophysical and in situ instruments. This episode focuses on the in situ instruments, which will study the particle, magnetic, radio and plasma environment in the Jupiter system. A magnetometer (J-MAG) equipped with sensors will characterise the Jovian magnetic field and its interaction with that of Ganymede, and will study the subsurface oceans of the icy moon. The Particle Envi…

An international team of researchers has used the NASA/ESA/CSA James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet’s thermal emission: heat energy given off in the form of infrared light detected by Webb’s Mid-Infrared Instrument (MIRI). The result indicates that the planet’s dayside has a temperature of about 500 kelvins (roughly 230°C), and suggests that it has no significant atmosphere. View the full article

The two spacecraft forming ESA’s Proba-3 mission for precise formation flying in orbit are now complete. All the instruments and sensors allowing them to manoeuvre to millimetre scale precision relative to one another have been integrated aboard, and the pair are fully wrapped in multi-layer insulation – ready to be tested in simulated space conditions.

Ever since its launch in 1990, the NASA/ESA Hubble Space Telescope has been an interplanetary weather observer, keeping an eye on the ever-changing atmospheres of the largely gaseous outer planets. And it’s an unblinking eye that allows Hubble’s sharpness and sensitivity to monitor a kaleidoscope of complex activities over time. Today new images are shared of Jupiter and Uranus.

Video: 00:02:20 In the week of 13-17 March 2023, more than 1400 students attended the ESA School Days event at ESRIN, the ESA Centre for Earth Observation located in Frascati, near Rome, Italy. The students and their teachers, coming from Lazio and other Italian regions, discovered more about ESA and the projects it is involved in, thanks also to creative hands-on labs, a visit to the Earth observation multimedia centre and the launch of rocket models. During the full-day visit, the focus was on themes such as Earth observation, satellites in orbit, ESA launch programmes, asteroid tracking, and how space exploration and ESA’s activities benefit daily life. Italia…

Video: 00:03:03 Explore the fascinating landing site of NASA’s Perseverance rover in this fly-through video, featuring new views of Jezero crater and its surroundings from ESA’s Mars Express and NASA's Mars Reconnaissance Orbiter. The video begins by panning around Jezero crater, which can be seen in the centre background surrounded by textured and cratered terrain. The crater moves into the foreground roughly halfway through, when an outflow channel can be seen snaking away from the crater wall and towards the camera perspective. Two inflow channels (Neretva Vallis and Sava Vallis, found on the western-northwestern rim of Jezero) then become visible; the most pro…

The final instalment of the sixth assessment report by the United Nations' Intergovernmental Panel on Climate Change (IPCC) has been released today. The report warns that the planet has already warmed 1.1°C above pre-industrial levels, resulting in more frequent and intense extreme weather events that are causing increasingly dangerous impacts on nature and people in every region of the world. The report includes a greater contribution of Earth observation data than its previous iterations in providing the physical evidence of Earth’s changing climate system – from sea-level rise, growing greenhouse-gas emissions and melting sea ice.

Video: 00:00:57 More than 5000 exoplanets have been discovered to date, but what do they look like? ESA’s dedicated exoplanet missions Cheops, Plato and Ariel are on a quest to find out. Cheops will focus its search on mini-Neptunes, planets with sizes between Earth and Neptune, on short orbits around their stars. Cheops will find out how large these planets are, and may detect whether the planets have clouds. Plato will look at all kinds of exoplanets and determine their sizes and ages. Plato’s instruments are so sensitive it may discover the first Earth-like planet on an Earth-like orbit. Finally, Ariel will look at the atmospheres of exoplanets using the techni…
