Video: 00:03:22 Join ESA astronaut Matthias Maurer inside the seven-windowed cupola, the International Space Station's "window to the world" and pan around to enjoy the view. The ESA - European Space Agency-built Cupola is the favourite place of many astronauts on the International Space Station. It serves not only as a unique photo spot, but also for observing robotic activities of the Canadian Space Agency's robotic arm Canadarm2, arriving spacecraft and spacewalks. Just outside the cupola and behind Matthias is a portion of the Soyuz MS-19 crew ship docked to the Rassvet module and the Prichal docking module attached to the Nauka multipurpose laboratory service module. Matthias was launched to the International Space Station on Crew Dragon Endurance as part of Crew-3 at 02:03 GMT/03:03 CET Thursday 11 November. His ESA mission on board is known as Cosmic Kiss and will see him live and work for approximately six months in orbit. Follow Matthias Access the other Cosmic Kiss 360º videos View the full article

Green and digital transition in Europe will benefit from ESA expertise that supports national plans for investing recovery and resilience funds in space projects. At the 303rd ESA Council meeting in Paris on 15 December 2021, ESA Member States took the decision to further the role of ESA as provider of expertise in support of national space plans, in particular in order to accompany the investment of Italian recovery and resilience funds in space programmes.

Video: 00:45:03 Replay of the 16 December 2021 online press briefing about the James Webb Space Telescope. Speakers: - Günther Hasinger, ESA Director of Science - Daniel Neuenschwander, ESA Director of Space Transportations - Thomas Zurbuchen, NASA’s Associate Administrator for science - Antonella Nota, ESA Webb Project Scientist - Gillian Wright, European Principal Investigator for the MIRI instrument Developed and constructed over more than 30 years, Webb is a remarkable feat of engineering and technology – with the largest astronomical mirror ever flown in space, sophisticated new scientific instruments, and a sunshield the size of a tennis court. Webb is designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy. The major contributions of ESA to the mission are: the NIRSpec instrument; the MIRI instrument optical bench assembly; the provision of the launch services; and personnel to support mission operations. In return for these contributions, European scientists will get a minimum share of 15% of the total observing time, like for Hubble. Webb’s partners are ESA, NASA and the Canadian Space Agency (CSA).

Ahead of the upcoming Ariane 5 launch of the James Webb Space Telescope, the Copernicus Sentinel-2 mission takes us over Kourou – home to Europe’s Spaceport in French Guiana, an overseas department of France. View the full article

A pretty special gift unwrapping will soon take place – a piercing tool built by ESA will open a Moon soil container from Apollo 17 that has gone untouched for nearly 50 years. The opening will allow the extraction of precious lunar gases which may have been preserved in the sample. View the full article

How did supermassive black holes form? What is dark matter? In an alternative model for how the Universe came to be, as compared to the ‘textbook’ history of the Universe, a team of astronomers propose that both of these cosmic mysteries could be explained by so-called ‘primordial black holes’.

In an astonishing feat of endurance, explorers Justin Packshaw and Jamie Facer Childs are a quarter of the way through a 3600-km kitesurf trek that takes them across the desolate heart of Antarctica. They are not pushing their physical and mental limits to the brink, facing howling gales and temperatures of –55°C just for the sake of adventure. They are gathering information to help scientists better understand how the body responds to extremes and taking unique measurements of their ice environment that will help complement ESA’s CryoSat mission to better understand how this giant ice sheet is evolving in response to climate change.

ESA’s Vega-C launch vehicle will fly in the second quarter of 2022 offering more performance to all orbits and extended mission flexibility at a similar cost to the current Vega. A new contract aims to widen these mission capabilities to capture new opportunities and satisfy emerging market needs to 2027. View the full article

The notion of living in a bubble is usually associated with negative connotations, but all life on Earth is dependent on the safe bubble created by our magnetic field. Understanding how the field is generated, how it protects us and how it sometimes gives way to charged particles from the solar wind is not just a matter of scientific interest, but also a matter of safety. Using information from ESA’s Cluster and Swarm missions along with measurements from the ground, scientists have, for the first time, been able to confirm that curiously named bursty bulk flows are directly connected to abrupt changes in the magnetic field near Earth’s surface, which can cause damage to pipelines and electrical power lines.

Video: 00:00:57 The James Webb Space Telescope (Webb) is designed to answer fundamental questions about the Universe. One of Webb’s key science goals is to study the nearby cosmos: uncovering hidden parts of our Solar System, peering inside dust clouds where stars and planetary systems are forming, and revealing the composition of exoplanets in more detail. Exoplanets Thanks to its powerful capabilities at infrared wavelengths, Webb will offer a unique view of the outer planets in our own magnificent Solar System. Looking beyond, Webb will study in detail the atmospheres of a wide diversity of exoplanets. Webb can study exoplanets as they pass in front of their respective host stars (known as transiting). The tiny fraction of light that passes through the atmosphere interacts with atoms and molecules there. That light then carries information about them, which scientists use to infer conditions such as temperature, chemical composition and formation history. Webb will search for atmospheres similar to Earth’s, and for the signatures of key substances such as methane, water, oxygen, carbon dioxide and complex organic molecules, in the exciting hope of finding the building blocks of life. In this way, Webb will complement ESA’s Ariel mission, a space telescope scheduled for launch in 2029 that will study what exoplanets are made of, how they form and how they evolve. The lifecycle of stars Webb will determine how and why clouds of dust and gas collapse into stars, or become gas giant planets or brown dwarfs. Observing in the infrared part of the spectrum, Webb will be capable of peering through the dusty envelopes around newly born stars, and its superb sensitivity will allow astronomers to directly investigate the faint, earliest stages of starbirth, known as ‘protostellar cores’. Throughout their lifetimes, stars transform the Universe’s simple elements into heavier elements and spread them throughout the cosmos through stellar winds and supernova explosions, along with the precious heavy metals that enrich the cosmos to form new generations of stars. Webb will study such supernova explosions, which are explosive deaths of massive stars and are among the most energetic events in the Universe. Webb will also study brown dwarfs: astronomical objects that are more massive than a planet but less massive than a star. Webb is an international partnership between NASA, ESA and the Canadian Space Agency (CSA). View the full article
