Video: 00:01:01 On 1 September 2023 ESA’s all-new Ariane 6 launch vehicle fired its two upper stage engines to simulate the way they will have to operate together at German aerospace agency DLR’s engine test centre in Lampoldshausen, Germany. The test – of the new Vinci engine and a smaller Auxiliary Power Unit (APU) – took place on a purpose-built test bench. Vinci, the upper stage engine of Ariane 6 fed by liquid hydrogen and oxygen, can be stopped and restarted multiple times – to place satellites into different orbits and then de-orbit the upper stage, so it is not left behind as hazardous debris in space. The APU makes it possible for Vinci to restart in spa…

Video: 00:05:10 Space exploration presents unique health challenges for astronauts due to lack of gravity, isolation, and radiation exposure. ESA's SciSpacE activities aim to comprehend these effects and their implications for human well-being during extended missions. ESA collaborates with researchers to conduct experiments in microgravity and analogue environments, shedding light on the consequences of space stressors. One critical concern is muscle and bone atrophy. Despite daily exercise routines, astronauts face deterioration. ESA is investigating electrical stimulation as a potential countermeasure, with tests planned on board the International Space Station…

Video: 00:03:06 Huginn, Andreas Mogensen's second mission to the International Space Station, is now underway. Together with Crew-7, the ESA astronaut launched aboard the Crew Dragon spacecraft Endurance on 26 August 2023, at 09:27 CEST (08:27 BST). Alongside him are NASA's Jasmin Moghbeli, Satoshi Furukawa from JAXA, and Konstantin Borisov from Roscosmos. The crew will spend approximately six months on the Space Station, 420 kilometres above Earth. This isn't Andreas's first journey into space. In 2015, he participated in the 10-day "iriss" mission. However, Huginn marks his first launch from NASA's Kennedy Space Center in Florida, USA, and his inaugural experien…

Image: The graceful winding arms of the grand-design spiral galaxy M51 stretch across this image from the NASA/ESA/CSA James Webb Space Telescope. Unlike the menagerie of weird and wonderful spiral galaxies with ragged or disrupted spiral arms, grand-design spiral galaxies boast prominent, well-developed spiral arms like the ones showcased in this image. This galactic portrait is a composite image that integrates data from Webb’s Near-InfraRed Camera (NIRCam) and the innovative Mid-InfraRed Instrument (MIRI), half of which was contributed by Europe. In this image the dark red regions trace the filamentary warm dust permeating the medium of the galaxy. The red regions s…

Dropcoal, short for Drop Coalescence, is a research project that studies how droplets form in space and on Earth. The results will grant insights into raindrop and cloud formation, fuel combustion and interactions between materials, all with broad implications for industry and academy. They also play a crucial role in administering medicine to astronauts during lengthy and far-reaching space missions. View the full article

Video: 00:05:52 On 26 August 2023, at 09:27 CEST (08:27 BST), Crew-7 aboard the Crew Dragon spacecraft Endurance embarked on a journey to the International Space Station. Watch the full coverage of their launch from pad 39A at Kennedy Space Center in Florida, USA. Andreas serves as pilot and has become the first European to take that role. He is sitting next to Crew-7's commander and NASA astronaut Jasmin Moghbeli. Andreas is responsible for the spacecraft’s performance and systems. Accompanying them are mission specialists Satoshi Furukawa from JAXA and Konstantin Borisov from Roscomos. Andreas’s Huginn mission officially begins when Endurance docks with the Stat…

The ESA/NASA Solar Orbiter spacecraft has discovered a multitude of tiny jets of material escaping from the Sun’s outer atmosphere. Each jet lasts between 20 and 100 seconds, and expels plasma at around 100 km/s. These jets could be the long-sought-after source of the solar wind. View the full article

Confirmed by the World Meteorological Organization, July 2023 was the hottest month on record, with high-impact weather continuing through August. These records are based on air temperatures, but measurements of the temperature of Earth’s surface taken from space are also essential to tracking the impact of climate change, and to being better prepared for such extremes – especially when it comes to cities where stifling urban heat islands form.
