  • Muscle stimulation to enhance astronaut health

    Muscle stimulation to enhance astronaut health

    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.

    The “Muscle Stimulation” experiment is a centrepiece of this research. By applying controlled electric currents to leg muscles, the study aims to enhance muscle mass, strength, and recovery. Complementary assessments, including MRI scans, microcirculation analysis, and blood samples, will provide a comprehensive understanding of the efficacy.

    Addressing these challenges could yield benefits on Earth too. The insights gained could translate to better healthcare for diverse populations, from the elderly to clinical patients and athletes.

    ESA’s dedication to advancing space exploration while safeguarding astronauts’ physical health underscores its commitment to a sustainable and thriving space programme. Through research and innovative solutions, humanity edges closer to conquering the challenges of extended spaceflight and improving life on our home planet.

  • Mating Hera: two become one

    Mating Hera: two become one

    Hera is complete. ESA’s asteroid mission for planetary defence was built and prepared in two halves, but now, through a painstaking operation, they have been mated together to make a single spacecraft, ready for full-scale testing of its readiness for space.

    The mating took place at OHB Bremen in Germany, with Hera’s Core Module raised more than 3 m above its Propulsion Module then gradually and carefully slotted into place, over a three-hour period. The modules had been placed in cages to ensure their correct alignment relative to each other down to a few tenths of a millimetre.

    Hera’s Propulsion Module incorporates its propellant tanks – housed within a central titanium cylinder, the ‘backbone’ of the spacecraft – along with piping and thrusters, which will have the job of hauling the mission across deep space for more than two years, then to manoeuvre around the Dimorphos and Didymos asteroids.

    Meanwhile Hera’s Core Module can be thought of as the brains of the mission, hosting its onboard computer, mission systems and instruments.

    Once the tip of the Propulsion Module cylinder met the top deck of the Core Module the mating was complete. Then an initial test bolt was inserted to check the alignment was entirely correct in advance of the two modules being fully bolted together.

    The combined Hera spacecraft is scheduled to go through a test campaign to assess its readiness for spaceflight, along with the two CubeSats it will carry aboard, in preparation for its October 2024 lift-off.

    Zoom into the cosmic seahorse 🔍 #shorts

    This image was captured by NIRCam, Webb’s primary near-infrared camera, and contains the lensing galaxy cluster SDSS J1226+2149. It lies at a distance of around 6.3 billion light-years from Earth, in the constellation Coma Berenices. By combining Webb’s sensitivity with the magnifying effect of gravitational lensing, astronomers were able to use this gravitational lens to explore the earliest stages of star formation in distant galaxies. To do so, they relied on earlier studies by the NASA/ESA Hubble Space Telescope, which provided the ‘prescription’ for this gravitational lens.

  • Artemis II astronauts visit European Service Module-2

    Artemis II astronauts visit European Service Module-2

    During Artemis I the European Service Module (ESM) surpassed expectations. Now, as we set our sights on Artemis II, the European Service Module is ready to once again serve as Orion’s primary power and propulsion component and keep the spacecraft at the right temperature and on course. And this time, with real astronauts on board.

    ESM-2 stands as a testament to ESA’s contributions to NASA’s Orion spacecraft and the Artemis programme, ensuring the crew will have the essentials – from electricity to temperature control – in the vastness of space.

    Next up, ESM-2 will be connected with the crew module to create the Artemis II vehicle. It will then be thoroughly tested before launch scheduled for next year.

    ESA is committed to send astronauts beyond low-Earth orbit and ultimately to the surface of the Moon and beyond. ESM is a key contribution to this joint international endeavour.

    This video features interviews with:
    – Philippe Berthe, ESA’s European Service Module Project Coordination manager
    – Kai Bergemann, Airbus deputy programme manager for Orion and the European Service Module
    – Jeremy Hansen, Canadian Space Agency Artemis II astronaut
    – Debbie Korth, NASA deputy programme manager for Orion

    Heatwave hits Antarctica ♨️ #shorts

    According to the @worldmetorg, July 2023 is likely to have been the hottest month on record. While much of Europe, North America and Asia suffered the immediate consequences of these brutal temperatures, extreme events are also hitting hard far away in the icy reaches of Antarctica. In a paper published today, scientists highlight Antarctica’s vulnerability to extremes and the role that satellites play in monitoring this remote region.

  • How will astronauts keep their spacesuit underwear clean? 🌚 #space #moon #shorts

    How will astronauts keep their spacesuit underwear clean? 🌚 #space #moon #shorts

    In the vast expanse of space, astronauts face a unique challenge – the need to share spacesuits during prolonged spacewalks. These suits, including their inner linings that come into direct contact with the astronauts’ skin, tend to accumulate bodily fluids over time. Drawing a rather relatable analogy, it’s akin to sharing underwear in space!

    However, the practicality of washing these spacesuit interiors on lunar surfaces or beyond presents a significant hurdle. To counter this, a dedicated group of researchers is delving into innovative strategies to curb the growth of potentially harmful microbes within the inner layers of these suits.

    Here’s where the solution gets intriguing: the world of microbiology offers a fascinating approach. Certain types of microbes possess ‘secondary metabolites’ that allow them to combat other microbes. These compounds are not only diverse in colour but also possess antibiotic properties. The ingenious idea involves integrating these microbial warriors into the very fabric of the spacesuit’s inner layer.

    This pioneering research isn’t confined solely to the realm of spacesuits; its implications extend far beyond. The outcomes hold the potential to revolutionise the field of antimicrobial treatments and smart textile technologies right here on Earth. As we gear up for lunar expeditions and beyond, these microbial-fighting fabrics could play a pivotal role in ensuring astronauts’ health and well-being while opening new frontiers of innovation back home.

  • How Euclid will map the Universe

    How Euclid will map the Universe

    ESA’s Euclid mission will create a 3D-map of the Universe that scientists will use to measure the properties of dark energy and dark matter and uncover the nature of these mysterious components. The map will contain a vast amount of data, it will cover more than a third of the sky and its third dimension will represent time spanning 10 billion years of cosmic history.

    But dealing with the huge and detailed set of novel data that Euclid observations will produce is not an easy task. To prepare for this, scientists in the Euclid Consortium have developed one of the most accurate and comprehensive computer simulations of the large-scale structure of the Universe ever produced. They named this the Euclid Flagship simulation.

    Running on large banks of advanced processors, computer simulations provide a unique laboratory to model the formation and evolution of large-scale structures in the Universe, such as galaxies, galaxy clusters, and the filamentary cosmic web they form. These state-of-the-art computational techniques allow astrophysicists to trace the motion and behavior of an extremely large number of dark-matter particles over cosmological volumes under the influence of their own gravitational pull. They replicate how and where galaxies form and grow, and are used to predict their distribution across the celestial sphere.

    Explore the Euclid Flagship simulation in this video and get a sneak preview of the structure of the dark Universe, as we currently model it. New insights will be brought to you by the Euclid mission in the coming years.

  • Sonification of Aeolus

    Sonification of Aeolus

    ESA’s Earth Explorer Aeolus satellite was launched in August 2018 on a trailblazing mission to show how profiling Earth’s winds from space can improve weather forecasts and climate models. Data from its pioneering wind-mapping laser, which at one stage was thought a nigh-impossible feat of engineering, has been used by leading weather forecasting services throughout Europe.

    Marking the end of Aeolus’ remarkable mission, ESA worked with composer Jamie Perera to create a woodwind piece from data that spans the lifetime of the satellite’s life in orbit around Earth.

    In the resulting orchestral piece, every second is a day in the life of Aeolus, with data represented by the following instruments:

    Piccolo: Rayleigh Top Altitude (the tops of clouds)
    Flute: Rayleigh Observation Type (density of clouds)
    Oboe: Rayleigh Reference Temperature (wind temperature)
    Clarinet 1: Rayleigh Wind Velocity (wind velocity)
    Clarinet 2: Rayleigh Wind Reference Pressure (air pressure)
    Bassoon/Bass Clarinet: Rayleigh Bottom Altitude (Earth’s surface)
    Ambient Synth: Validity Flag 0 (Aeolus downtime)

    You can also hear landmark events such as volcanic eruptions represented by drums, hurricanes represented by wind sound effects, and the Coronavirus pandemic represented by a pulsing synth.

  • BepiColombo’s third Mercury flyby

    BepiColombo’s third Mercury flyby

    Watch Mercury appear from the shadows as the ESA/JAXA BepiColombo spacecraft sped by the planet’s night side during its 19 June 2023 close flyby, and enjoy a special flyover of geologically rich terrain.

    The first part of the movie is composed of 217 images captured by BepiColombo’s monitoring camera M-CAM3. The image sequence starts from 19:46:25 UTC on 19 June 2023, at an altitude of 1 789 km above the planet’s surface, and ends at 20:34:25 UTC on 20 June 2023, when BepiColombo was 331 755 km away. The image cadence was roughly once per minute around closest approach, but much slower in the later phases.

    The second part of the movie cuts to a flyover of a special region of interest, rotating around features such as the 600 km-long Beagle Rupes curved escarpment and the elongated Sveinsdóttir impact crater that it cuts through. It also features the 218 km-wide Manley Crater and the straight Challenger Rupes scarp. At the end, the animated topography fades out and the projected image used for 3D reconstruction appears. Regions like these will be important for BepiColombo’s main science mission, to learn more about Mercury’s geological history.

    Music was composed for the sequence by ILĀ, with the assistance of AI tools developed by the Machine Intelligence for Musical Audio (MIMA) group, University of Sheffield.

  • Euclid | ESA’s mission into the unknown

    Euclid | ESA’s mission into the unknown

    ESA’s Euclid mission is designed to bring the dark side of the Universe to light. Based on the way galaxies rotate and orbit one another, and the way in which the Universe is expanding, astronomers believe that two unseen entities dominate the composition of our cosmos. They call these mysterious components dark matter and dark energy, yet to date we have not been able to detect either of them directly, only inferring their presence from the effects they have on the Universe at large.

    To better understand what dark matter and dark energy may be, we need a mission that can more closely reveal what effects they have had on galaxies, galaxy clusters and the expansion of the Universe itself. Euclid is that mission.

    ESA’s Euclid mission will create a 3D-map of the Universe, with the third dimension representing time itself. The further away a galaxy is located, the longer its light has taken to reach us and so the earlier in cosmic history we will see it. By observing billions of galaxies out to a distance of 10 billion light-years, scientists will be able to chart the position and velocity of galaxies over immense distances and through most of cosmic history, and trace the way the Universe has expanded during that time. Euclid’s extraordinary optics will also reveal subtle distortions in the appearance of galaxies.

    From this wealth of new data, astronomers will be able to infer the properties of dark energy and dark matter more precisely than ever before. This will help theorists pin down the nature of these mysterious components and develop a refined understanding of how gravity behaves at the largest distances.

    From French Guiana to the stars: Ariane 5’s 25-year journey

    For a quarter century, Ariane 5 has been Europe’s heavy-lift workhorse. Flying from Europe’s Spaceport in French Guiana, Ariane 5 has carried to space a long series of commercial and scientific missions. Notable payloads include ESA’s comet-chasing Rosetta, a dozen of Europe’s Galileo navigation satellites – orbited with just three launches – the NASA/ESA/CSA James Webb Space Telescope and, in April 2023, ESA’s Juice mission to Jupiter.

    Ariane 5 more than doubled the mass-to-orbit capacity of its predecessor, Ariane 4, which flew from 1988 until 2003 as a favourite of the telecommunications industry with its need to put large payloads into very high geosynchronous orbits. Ariane 5’s capacity enabled it to orbit two large telecommunications satellites on a single launch, or to push very large payloads into deep space.

    After 117 flights, Ariane 5 is being replaced by an all-new launch vehicle, Ariane 6.

    Nicolas Bobrinsky on Excellence | ESA Masterclass

    The level of practical expertise, technical and operational expertise required to operate in such a fast-paced, rapidly changing environment such as space needs to be permanently developed and improved to maintain the technical excellence at the right level. But the constant improvement of the technical and operational knowledge is an exciting journey. Nicolas has experienced this first-hand since he joined the European Space Agency Operation Centre as Ground Station Engineer. As a young engineer at ESA, you can gain extremely valuable expertise through launch campaigns, test and validation campaigns, time at the console in the operation control room together with your team, witnessing and learning from the whole life cycle of a real satellite mission, one impossible thing at the time.

    With 35 years of experience at ESA, Nicolas Bobrinsky is the former Head of Ground Systems Engineering & Innovation Department. He initiated and further managed the Space Situational Awareness and later the ESA Space Safety Programme.

    In four episodes of this new series of ESA Masterclass, Nicolas takes us through major events in his career at ESA, covering cornerstone missions, first attempts, overcoming technical challenges, leading diverse teams and solving the unexpected problems that are part of any space endeavour.

    Nicolas Bobrinsky on People management and Teamwork | ESA Masterclass

    Imagine you are singing in a choir. You are doing your best, just like everybody else. Suddenly, somebody turns to you and points out that you are not singing the right note. If you are told off in a harsh way, you may feel bad about it, and if this happens too often you might not only feel upset about the choir but might even leave it for good. Eventually, the whole choir could end if everybody just leaves.

    It is the duty of the choir conductor (the ESA team head) to be able to address every single situation in the right way, to make everyone feel heard and encouraged.

    In the third video of this new series of ESA Masterclass, Nicolas shares some lessons learned in his decades as a team leader on what it takes to keep a team together through mutual trust and recognition and make all members work in a harmonious way, like singers of a well-tuned choir.

    With 35 years of experience at ESA, Nicolas Bobrinsky is the former Head of Ground Systems Engineering & Innovation Department. He initiated and further managed the Space Situational Awareness and later the ESA Space Safety Programme.

  • Nicolas Bobrinsky on Space Safety | ESA Masterclass

    Nicolas Bobrinsky on Space Safety | ESA Masterclass

    Satellites in orbit underpin our modern lives. They are used in many areas and disciplines, including space science, Earth observation, meteorology, climate research, telecommunication, navigation and human space exploration. However, as space activities have increased, a new and unexpected hazard has started to emerge: space debris.

    If space debris – uncontrolled human-made objects such as spent upper stages of rockets and pieces of satellites – hits a satellite, it could cause serious damage, which can even end a mission (as has happened in the past). If debris crashes on Earth’s surface, it could potentially hit populated areas.

    In this second video, Nicolas looks back on the first key steps taken at ESA to develop the Space Safety Programme, devoted to the detection, prevention and mitigation of threats originating from space. This includes not just space debris but also asteroids and space weather. The latter is an intense, occasional energetic storm of particles and material emitted by the Sun. Mitigating these hazards protects our planet, society and economically-important infrastructure on Earth and in orbit.

    A key element for the forecasting and prevention of space weather is to observe the Sun from the side. Discover more in this second video of the ESA Masterclass with Nicolas Bobrinsky. With 35 years of experience at ESA, Nicolas Bobrinsky is the former Head of Ground Systems Engineering & Innovation Department. He initiated and further managed the Space Situational Awareness and later the ESA Space Safety Programme.

    Zoom into NGC 5068 🔍 #shorts

    This video takes the viewers on a journey to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.

    With its ability to peer through the gas and dust enshrouding newborn stars, the NASA/ESA/CSA James Webb Space Telescope is the perfect telescope to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to visible-light observatories like Hubble or the VLT. The keen vision at infrared wavelengths of two of Webb’s instruments — MIRI and NIRCam — allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. This image combines the capabilities of these two instruments, providing a truly unique look at the composition of NGC 5068.

    Nicolas Bobrinsky on Innovation and Risk Management | ESA Masterclass

    Innovation is triggered by many drivers. One of these is the constant need for ESA to develop innovative solutions,such asuniquespacecrafttechnologies.

    In this first video, Nicolas recalls how he and his team had to think outside the box to find a solution for ESA to communicate with Ulysses. Thespacecraft was flyingaround the north pole of the Sun,which ismuch fartherin deep spacethan satellites had beenlaunched up to that point.

    The success of this solution motivated the decision to build ESA’sfirst deep-space communications antennas in New Norcia, in Australia, thus enabling many ESA scientific firstsin deep-space exploration.

    The antennas would, some decades after, be critically important receivers forthe messages sent by the very distant Rosetta probe, on its quest to find and land on the comet 67P/Churyumov–Gerasimenko, and other ESA science and exploration missions such as Mars Express, Venus Expressand Cassini-Huygens.

  • Picking up lightsabres for Mars

    Picking up lightsabres for Mars

    Detect, fetch and collect. A seemingly easy task is being tested to find the best strategy to collect samples on the martian surface, some 290 000 million km away from home.

    Testing technologies for Mars exploration is part of the daily job of Laura Bielenberg, an ESA graduate trainee for the Mars Sample Return campaign.

    The test takes place at the rock-strewn recreation of the Red Planet at ESA’s ESTEC technical centre in Noordwijk, the Netherlands. The nickname of this test site is the ‘Mars Yard’ and is part of the Planetary Robotics Laboratory.

    The tube is a replica of the sample caches that NASA’s Perseverance rover is leaving on Mars hermetically sealed with precious martian samples inside. They are called RSTA, an acronym of Returnable Sample Tube Assembly, and to most people on Earth they look like lightsabers.
    Laura is investigating sample tube collection strategies, from autonomous detection to pose estimation of sample tubes on Mars, with a testbed called the RABBIT (RAS Bread Boarding In-house Testbed).

    The Sample Transfer Arm will need to load the tubes from the martian surface for delivery towards Earth. ESA’s robotic arm will collect them from the Perseverance rover, and possibly others dropped by sample recovery helicopters as a backup.

    Besides cameras and sensors, the team relies on neural networks to detect the tubes and estimate their pose. Inspired by the way the human brain works, neural networks mimic the way biological neurons signal to one another.

    What would you do after 60 days in bed? 🛌 #shorts

    Lying in bed for a full 60 days – with one shoulder always touching the mattress – might sound like bliss, but add cycling, spinning and constant medical tests to the equation and it becomes a challenging experience for the sake of human space exploration.

    A group of 12 volunteers are bracing themselves for a bedridden journey that put them into a compulsory reclined lifestyle. Participants are kept in beds tilted 6 degrees below the horizontal with their feet up – meals, showers and toilet breaks included.

    As blood flows to the head and muscle is lost from underuse, researchers are charting how their bodies react. Bedrest studies offer a way of testing measures to counter some of the negative aspects of living in space.

    During space missions, astronauts’ bodies go through a wide array of changes due to lack of gravity – everything from their eyes to their heart is affected, and muscles and bones start to waste away.

    Juice-y breaking news from depth of space 🚨 #shorts

    After Juice launched, flight controllers noticed the ice-penetrating RIME antenna was not fully deployed. They suspected a tiny pin was the culprit.

    With a mechanical jolt and some ingenious tactics from our mission control, the 16-metre-long boom was unleashed on 12 May!

    RIME is now ready to help explore Jupiter’s icy moons when Juice arrives in the Jovian system in 8 years. 🌌🛰️

  • Andreas Mogensen next mission to the International Space Station | Huginn Mission

    Andreas Mogensen next mission to the International Space Station | Huginn Mission

    The name of Andreas’s second mission to the Space Station is ‘Huginn’. Inspired by Norse mythology, the name is taken from one of two ravens who serve the god Odin. Called Huginn and Muninn, these two birds sit on Odin’s shoulders and are sent flying across the world at dawn. They return at night to inform him of the many events they have seen and heard. In Old Norse, ‘Huginn’ means ‘thought’ and ‘Muninn’ means ‘mind’ or ‘memory’.

    ESA astronaut Andreas Mogensen is going on his first long-duration mission to the International Space Station. Andreas will be the pilot on the SpaceX Crew Dragon that will carry him and the rest of Crew-7 to the Space Station – a first for a European!
    Representing Europe in space, Andreas will carry out science throughout his mission and bring back the knowledge to Earth, for the benefit of humankind.

    Visit esa.int/huginn for more information on the Huginn mission.

  • World’s ice is melting faster than ever

    World’s ice is melting faster than ever

    As global temperatures increase, the melting of the massive ice sheets that blanket Antarctica and Greenland has accelerated, making a significant contribution to sea-level rise. In total, Earth is losing around a trillion tonnes of ice each year – which is not being replenished.

    Andrew Shepherd of the University of Leeds is a leading climate scientist working with ESA and @NASA. Join Andrew as he discusses how long-term satellite observations from ESA’s Climate Change Initiative are key in monitoring changes in ice sheets over decades.

  • I want to break free… 🎶 #shorts

    I want to break free… 🎶 #shorts

    When a spacecraft launches on a mission to another planet it must first break free of the Earth’s gravitational field. Once it has done that, it enters interplanetary space, where the dominant force is the gravitational field of the Sun.

    The spacecraft begins to follow a curving orbit, around the Sun, which is similar to the orbit of a comet. When this orbit brings it close to its target destination the spacecraft must fire a retrorocket to slow down and allow itself to be captured by the gravitational field of its target. The smaller the target, the more the spacecraft must slow down.

    Sometimes passing a planet can result in the spacecraft being accelerated, even without the spacecraft firing any of its thrusters. This is known as the ‘slingshot’ effect. Such ‘gravity assist’ manoeuvres are now a standard part of spaceflight and are used by almost all our interplanetary missions. They take advantage of the fact that the gravitational attraction of the planets can be used to change the trajectory and speed of a spacecraft.

    The amount by which the spacecraft speeds up or slows down is determined by whether it is passing behind or in front of the planet as the planet follows its orbit. When the spacecraft leaves the influence of the planet, it follows an orbit on a different course than before.

    Setting sail for safer space ⛵️ #shorts

    The Drag Augmentation Deorbiting System Nano – a 3.6-sq-m aluminium-coated polyamide membrane attached to four metallic booms – deployed from a 10 cm box aboard a satellite platform launched in 2021 used to deliver miniature ‘CubeSats’ into their individual orbits.

    By increasing the overall area of the satellite, the sail will increase the gradual air drag acting upon it from atoms at the top of the atmosphere, and speed up its atmospheric reentry.
