05/24/2019Micro-Cameras and Space Exploration to join Pioneer-IODA project
Space cameras to monitor the deployment of satellites and check the health of spacecraft will be developed under the Pioneer-IODA project by Micro-Cameras and Space Exploration based in Neuchâtel, Switzerland.
05/23/2019Clocks, gravity, and the limits of relativity
The International Space Station will host the most precise clocks ever to leave Earth. Accurate to a second in 300 million years the clocks will push the measurement of time to test the limits of the theory of relativity and our understanding of gravi...
05/23/2019A unique experiment to explore black holes
What happens when two supermassive black holes collide? Combining the observing power of two future ESA missions, Athena and LISA, would allow us to study these cosmic clashes and their mysterious aftermath for the first time.
05/17/2019Mission control 'saves science'
Every minute, ESA’s Earth observation satellites gather dozens of gigabytes of data about our planet – enough information to fill the pages on a 100-metre long bookshelf. Flying in low-Earth orbits, these spacecraft are continuously taking the pulse o...
05/17/2019Satellites yield insight into not so permanent permafrost
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth’s surface. Ground that has been frozen for thousands of years is also thawing, adding to the climate...
05/16/2019A quarter of glacier ice in West Antarctica is now unstable
By combining 25 years of ESA satellite data, scientists have discovered that warming ocean waters have caused the ice to thin so rapidly that 24% of the glacier ice in West Antarctica is now affected.
05/16/2019The air we breathe
Air pollution is a global environmental health problem, especially for those living in urban areas. Not only does it negatively impact our ecosystems, it considerably affects our health. According to the World Health Organization (WHO), around 8 milli...
05/15/2019Tug-of-war drives magnetic north sprint
As far as we know, Earth’s magnetic north has always wandered, but it has recently gained new momentum and is making a dash towards Siberia at a pace not seen before. While this has some practical implications, scientists believe that this sprint is b...
05/15/2019Downstream Gateway: bringing space down to Earth
ESA is launching its Downstream Gateway, a ‘one-stop shop’ service for all downstream opportunities, creating links between new and emerging business sectors and the capabilities being developed in ESA programmes.
05/15/2019Monitoring Earth’s shifting land
The monitoring of land subsidence is of vital importance for low-lying countries, but also areas which are prone to peculiar ground instability.
05/15/2019Reprogrammable satellite takes shape
The payload and platform of the first European satellite that can be completely reprogrammed after launch have been successfully joined together. The assembly of Eutelsat Quantum took place in the Airbus facility in Toulouse, France, on 10 May.
05/15/20193D Earth in the making
A thorough understanding of the ‘solid Earth’ system is essential for deciphering the links between processes occurring deep inside Earth and those occurring nearer the surface that lead to seismic activity such as earthquakes and volcanic eruptions,...
05/15/2019Water cycle wrapped
As our climate changes, the availability of freshwater is a growing issue for many people around the world. Understanding the water cycle and how the climate and human usage is causing shifts in natural cycling processes is vital to safeguarding suppl...
05/14/2019Mapping salty waters
The length and precision with which climate scientists can track the salinity, or saltiness, of the oceans is set to improve dramatically according to researchers working as part of ESA’s Climate Change Initiative.
05/14/2019New potential for tracking severe storms
Even just within the last couple of months, Cyclones Fani, Idai and Kenneth have brought devastation to millions. With the frequency and severity of extreme weather like this expected to increase against the backdrop of climate change, it is more impo...
05/14/2019Jakobshavn Isbrae Glacier bucks the trend
Our planet works in mysterious ways. We are all used to hearing about the world’s ice being the first casualty of climate change and, indeed, it is declining fast. However, recent findings show that one glacier is not conforming to the norm – it’s act...
05/13/2019How Venus and Mars can teach us about Earth
One has a thick poisonous atmosphere, one has hardly any atmosphere at all, and one is just right for life to flourish – but it wasn’t always that way. The atmospheres of our two neighbours Venus and Mars can teach us a lot about the past and future s...
05/13/2019Joining forces on Earth science to benefit society
With human activity leaving its indelible mark on the landscape and affecting the climate, our natural world is changing faster than at any other time in history. Science is fundamental to understanding environmental change so that these huge challeng...
05/13/2019Space Station science looking at Earth
In this edition of our bi-weekly update on European research run on the International Space Station, we’re taking our cue from the Living Planet Symposium – the largest conference on Earth Observation taking place this week in Milan, Italy – and focus...
05/13/2019Spotlight on the pulse of our planet
Satellites deliver crucial information to help solve what is our biggest global problem: climate change. As well as taking the pulse of our planet, satellite data are used in a myriad of daily applications, and are also used increasingly in business....
05/09/2019Maritime microsatellite ESAIL to test the waters as launch contract is signed
The first commercial microsatellite developed under ESA’s SAT?AIS programme for tracking ships, called ESAIL, has passed another milestone. On 9 May its Canadian operator exactEarth signed the launch service agreement with Arianespace.
05/06/2019Recognising sustainable behaviour
Solving the growing problem of space debris will require everyone who flies rockets and satellites to adhere to sustainable practices, which doesn’t always happen. Now there will be a way to recognise those who do.
05/06/2019Adding satnav to turn power grids into smart systems
An ESA-backed project is harnessing satnav to insert an intelligent sense of place and time to power grids, to provide early warning of potentially dangerous electricity network failures.
05/04/2019Stop ageing in space
Wrinkles, muscle pain, high blood pressure and a clumsy brain are all natural consequences of getting old. As our cells rust over time, a key to fighting chronic disease may be in tiny, smartly designed particles that have the potential to become an a...
05/02/2019Hera’s APEX CubeSat will reveal the stuff that asteroids are made of
From Earth asteroids appear as little more than dots in the sky. Europe’s miniature APEX spacecraft will operate as a mineral prospector in deep space, surveying the make-up of its target asteroids down to individual boulders, helping prepare the way...
05/02/2019Observing Gaia from Earth to improve its star maps
While ESA’s Gaia mission has been surveying more than one billion stars from space, astronomers have been regularly monitoring the satellite’s position in the sky with telescopes across the world, including the European Southern Observatory in Chile,...
05/01/2019Hera’s CubeSat to perform first radar probe of an asteroid
Small enough to be an aircraft carry-on, the Juventas spacecraft nevertheless has big mission goals. Once in orbit around its target body, Juventas will unfurl an antenna larger than itself, to perform the very first subsurface radar survey of an aste...
05/01/2019Swarm helps explain Earth’s magnetic jerks
Our protective magnetic field is always restless, but every now and then something weird happens – it jerks. Although scientists have known about these rapid shifts for some 40 years, the reason why they occur has remained a frustrating mystery, until...
