Atmospheric nitrogen dioxide is a harmful pollutant with significant impacts on air quality, climate and the biosphere. Although satellites have mapped nitrogen dioxide concentrations since the 1990s, their resolution was generally too coarse to pinpoint individual sources like power plants. In a recent study, researchers used imagery from Copernicus Sentinel-2 to observe nitrogen dioxide plumes from power plants for the first time – marking a significant advancement in air pollution monitoring.

As ESA’s Hera mission for planetary defence completes its pre-launch testing, its target asteroids have come into focus as tiny worldlets of their own. A special issue of Nature Communications published this week presents studies of the Didymos asteroid and its Dimorphos moon, based on the roughly five and a half minutes of close-range footage returned by NASA’s DART spacecraft before it impacted the latter body – along with post-impact images from the Italian Space Agency’s LICIACube.

Video: 00:01:02 ESA’s Jupiter Icy Moons Explorer (Juice) is coming back to Earth. Our fearless traveller is getting a nudge from Earth this summer, in the first of four ‘gravity assist manoeuvres’ that will put Juice on precisely the right path to arrive at Jupiter with the correct speed and direction in July 2031. This is the second big milestone in Juice’s journey to Jupiter, with the first being the launch into space on 14 April 2023. This second helping hand takes a very different form, with Juice flying past the Moon on 19 August, lining it up to fly past Earth on 20 August. The Earth flyby will line the spacecraft up for a flyby of Venus in summer 2025. Gravity is a fickle friend. These gravity assist flybys are a valuable technique to get Juice to Jupiter with less fuel, but they threaten derailment at any time. ESA mission operators will be keeping a very close eye on the spacecraft as it approaches the Moon-Earth system, making any tiny adjustments needed to keep the spacecraft on the right course.

Video: 00:08:21 The first half of 2024 saw hundreds of people across Europe building, cajoling, shipping, lowering, integrating, securing and protecting the precious pieces and parts that came together to create Ariane 6 – Europe’s new heavy-lift rocket. Huge engines, boosters and outer shells met tiny screws, electrical boards and masses of supercooled fuel. All this came together at Europe’s Spaceport in French Guiana, for the spectacular first launch of Ariane 6 on 9 July 2024, restoring Europe’s access to space. Get a glimpse at the teamwork, skill and care that went into this moment over many months, in this montage of Ariane 6 images, videos and timelapse photography spanning 30 January to 9 July 2024.

Image: Concordia is a research station in Antarctica that places you farther away from humankind than even the International Space Station. Every year, ESA sponsors a medical doctor to spend a year, or "winterover," at Concordia station. This year, our medical doctor is Jessica Kehala Studer, who is seen in this picture gazing at the Moon and the vast expanse of Antarctica. Around May, the Sun dips below the horizon for the last time, and the crew experiences four months of total darkness, with temperatures dropping to –80°C in winter. The station serves as an analogue for space, mirroring the challenges and conditions faced by astronauts such as isolation, extreme cold and darkness, along with their impact on health. Concordia is a unique platform for research in human physiology and psychology, as well as astronomy, meteorology, glaciology and other fields. Last Saturday, we celebrated Moon Day: 55 years ago on 20 July 1969, humankind stepped on the Moon for the first time during the Apollo 11 mission. Today, ESA is a key part of NASA's Artemis programme which aims to return humans to the Moon. The insights gained from ESA's experience in analogue facilities such as Concordia will be invaluable for this mission. Find out more about Concordia on our blog. View the full article

An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have directly imaged an exoplanet roughly 12 light-years from Earth. While there were hints that the planet existed, it had not been confirmed until Webb imaged it. The planet is one of the coldest exoplanets observed to date. View the full article

The Sentinel-2C satellite, the third Copernicus Sentinel-2 satellite, has arrived at the European spaceport in French Guiana for liftoff on the final Vega rocket in September. Sentinel-2C, like its predecessors, will continue to provide high-quality data for Copernicus – the Earth observation component of the EU Space Programme. View the full article
