ESA’s Mars Express has captured the rare moment of Mars’ small moon Deimos passing in front of Jupiter and its four largest moons – the focus of ESA’s upcoming Jupiter Icy Moons Explorer launching next year. Celestial alignments like these enable a more precise determination of the martian moons’ orbits. View the full article

We have now discovered 30 039 near-Earth asteroids in the Solar System – rocky bodies orbiting the Sun on a path that brings them close to Earth’s orbit. The majority of these were discovered in the last decade, showing how our ability to detect potentially risky asteroids is rapidly improving. View the full article

Image: A new image from the NASA/ESA/CSA James Webb Space Telescope reveals a remarkable cosmic sight: at least 17 concentric dust rings emanating from a pair of stars. Located just over 5000 light-years from Earth, the duo is collectively known as Wolf-Rayet 140. Each ring was created when the two stars came close together and their stellar winds (streams of gas they blow into space) met, compressing the gas and forming dust. The stars’ orbits bring them together about once every eight years; like the rings of a tree’s trunk, the dust loops mark the passage of time. In addition to Webb’s overall sensitivity, its Mid-Infrared Instrument (MIRI) is uniquely qualified to …

Video: 00:00:07 The ESA-led Solar Orbiter mission arrives at its next close approach to the Sun on 12 October 2022 at 19:12 UTC (21:12 CEST). This sequence of images shows the progress of the ESA/NASA spacecraft as it heads inwards on its voyage of discovery. The sequence begins on 20 September and finishes on 10 October. The sequence was taken by the Extreme Ultraviolet Imager (EUI) using the Full Sun Imager (FSI) telescope, and shows the Sun at a wavelength of 17 nanometers. This wavelength is emitted by gas in the Sun’s atmosphere with a temperature of around one million degrees. The colour on this image has been artificially added because the original waveleng…

Video: 00:02:22 At Europe’s Spaceport in French Guiana, a test model of the Ariane 6’s central core has been assembled for the first time. Ariane 6 is the first Ariane rocket to be assembled horizontally, which is simpler and less costly than more traditional vertical assembly. One of the P120C boosters can be seen from different angles during installation, before the rocket’s central core is moved to its launchpad and placed upright in its mobile gantry. With the central core and boosters in place, combined tests validate compatibility between all components of the complete launch system. Access the broadcast quality version of the video.

The kinetic impact of NASA’s DART spacecraft with the Dimorphos asteroid around its larger Didymos parent body has succeeded in shifting its orbit, meaning humankind’s first planetary defence test has been successful. Observations are continuing of the plume of the debris caused by the collision for as long as possible, as the asteroid system gradually recedes from Earth. View the full article

Certain estimates of Antarctica’s total contribution to sea-level rise may be over, or even underestimated, after researchers detected a previously unknown source of ice loss variability. In a new paper published in The Cryosphere, researchers using Copernicus Sentinel-1 data, found that glaciers feeding the George VI Ice Shelf speed up by approximately 15% during the Antarctic summer. This is the first time that such seasonal cycles have been detected on land ice flowing into ice shelves in Antarctica. View the full article

Following unusual seismic disturbances in the Baltic Sea, several leaks were discovered last week in the underwater Nord Stream 1 and 2 gas pipelines, near Denmark and Sweden. Neither pipeline was transporting gas at the time of the blasts, but they still contained pressurised methane – the main component of natural gas – which spewed out producing a wide stream of bubbles on the sea surface. With the unexplained gas release posing a serious question about the incident’s environmental impact, a suite of complementary Earth observation satellites carrying optical and radar imaging instruments were called upon to characterise the gas leak bubbling in the Baltic.

Video: 00:05:03 ESA astronaut Samantha Cristoforetti will soon complete her second mission to the International Space Station, Minerva. She was launched from Kennedy Space Center in late April, and since then has supported numerous European and international science experiments, as well as taken responsibility for all operations within the US Orbital Segment. In July 2022 she performed her first spacewalk, during which she carried out work in the Russian segment to bring the European Robotic Arm into operation. At the end of September 2022, she became the first European woman to hold the role of crew commander on the Station. This report provides a summary of the …
