You may have heard of the Trojans, two vast swarms of asteroids that lead and trail Jupiter on its orbit around the Sun. But the king of the planets doesn’t hold a monopoly on Trojan asteroids. The physics that gives rise to the formation of these distinctive collections of ancient rocks is the same for all planets – including Earth. While the existence of Earth Trojans had been theorised for many years, the first direct observation of one was confirmed just over a decade ago. Since then, no second Earth Trojan had been discovered – until now. In this Q&A, Toni Santana-Ros (TSR) from the University of Alicante and Institute of Cosmos Sciences of the University of Barc…

Image: ESA astronaut Samantha Cristoforetti is all smiles alongside her Crew-4 mates during a training session at SpaceX headquarters in Hawthorne, California, USA. Samantha is the next ESA astronaut to fly to space and is expected to be launched to the International Space Station in spring 2022. This is the second mission for Samantha who spent approximately 200 days in space in 2015 for her Futura mission. Samantha is launching with familiar faces. Fellow mission specialist Jessica Watkins was part of NASA’s NEEMO 23 crew, in which Samantha served as commander. The team spent 10 days living and working at the world's only undersea research station, Aquarius, located …

Hibernating astronauts could be the best way to save mission costs, reduce the size of spacecraft by a third and keep crew healthy on their way to Mars. An ESA-led investigation suggests that human hibernation goes beyond the realm of science-fiction and may become a game-changing technique for space travel. View the full article

One of the many serious consequences of the climate crisis is that precious permafrost is thawing, and this is unleashing even more carbon to the atmosphere and further exacerbating climate change. However, it’s complicated. For example, sometimes permafrost can thaw rapidly and scientists are unsure why and what these abrupt thaws mean in terms of feedback loops. This makes it difficult to predict the future impact on the climate. Thanks to an ESA–NASA initiative, new research digs deep into understanding the complexities of permafrost thaw and how carbon is released over time. View the full article

Image: Astronauts aboard the International Space Station farewelled over 2000 kg of scientific experiments and hardware on Sunday 23 January as a cargo Dragon spacecraft began its return to Earth. ESA astronaut Matthias Maurer captured the resupply vehicle in all its glory as it departed the orbital outpost at 15:40 GMT/16:40 CET. It splashed down approximately 29 hours later off the coast of Florida, USA. The SpaceX spacecraft arrived at the Space Station just before Christmas, bringing new experiments alongside Christmas treats. It returned with a bellyful of science, including several European experiments that were quickly transported to NASA’s Space Station…

Today, at 20:00 CEST, the James Webb Space Telescope fired its onboard thrusters for nearly five minutes (297 seconds) to complete the final post launch course correction to Webb’s trajectory. This mid-course correction burn inserted Webb toward its final orbit around the second Sun-Earth Lagrange point, or L2, nearly 1.5 million kilometres away from the Earth. View the full article

When Joe Biden was inaugurated as President one year ago, he fulfilled his promise to rejoin the Paris Agreement and set a course for the US to tackle the climate crisis by supporting global efforts to limit global warming. ESA recently joined the President’s Council of Advisors on Science and Technology by public video link to share European plans and expertise on measuring carbon dioxide and methane from space.

Video: 00:01:36 You’ve heard of spacewalking astronauts but how do astronauts run? Join ESA’s Matthias Maurer for a workout on the International Space Station’s T2 treadmill and explore Node 3 in 360°. Astronauts living and working on the International Space Station exercise for around two hours a day six days a week to stay fit and healthy in orbit. This helps counteract muscle and bone loss caused by life in microgravity. The T2 treadmill is attached to the wall in Node 3 and astronauts secure themselves using a harness and bungies. This creates a feeling like running on a treadmill on Earth. This clip is just a snapshot of the exercise Matthias performs in spac…
