With extreme weather events threatening to be more frequent and more severe as the climate crisis takes grip, it’s never been more important to have fast and accurate forecasts. ESA and Eumetsat are working hard to ensure that there will be a constant stream of weather data from space for the next decades and that these data will arrive faster and be more accurate compared to what we have today. It is therefore fitting that on World Meteorological Day, ESA can be assured that the first of the next generation weather satellites, Meteosat Third Generation

Use the right tool for the job is an often heard saying for any technician, or home hobbyist, and in spaceflight the advice counts double. When astronauts head on a spacewalk outside the International Space Station their tool belt is analysed, choreographed, prepared and checked in detail.

Many tools are made to measure, but in addition they are ordered on the tool belt to be easy to access at the time needed. When everything floats each tool is tethered to the spacewalk suit as well.

The study, in which the Universidad Carlos III de Madrid (UC3M) and the Universidad Estatal Paulista Júlio de Mesquita Filho (Júlio de Mesquita Filho Paulista State University) (UNESP) of Brazil are participating, analyzes the surface and dynamics of Apophis, an asteroid that will pass close to Earth in 2029.

The Apophis asteroid was discovered in 2004 and has been monitored since then due to its classification as a potentially hazardous asteroid (PHA), as it was estimated that it would have a 2% chance of hitting Earth. This possibility has already been ruled out and, according to the latest measurements, Apophis will reach its closest trajectory to Earth (38,000 kilometers) on the 13th of April, 2029.

This study analyzes the physical characteristics of this celestial body and the possible effects that its approach to Earth may have. Gabriel Borderes-Motta, a researcher at UC3M's Department of Bioengineering and Aerospace Engineering, explains that "collision is not the only possibility in approach events like this one. The between a planet and a body such as Apophis can change the shape of the body, break the body into , disintegrate possible loose stones on the asteroid's surface, or even remove other bodies orbiting the asteroid (such as rocks, satellites, or rings).

A newly released Android app will turn your smartphone into an instrument for crowdsourced science. Leave it by your window each night with your satnav positioning turned on and your phone will record small variations in satellite signals, gathering data for machine learning analysis of meteorology and space weather patterns.

Monitoring the constantly changing shape of the sea surface is important for scientific and societal applications such as ocean current forecasting, climate research, ship routing, cable laying, and debris tracking.

A project supported by the Discovery element of ESA’s Basic Activities recently investigated a new technique to measure sea surface topography very precisely. The project was based on an idea submitted by the Institute for Space Studies of Catalonia (IEEC) through the Open Space Innovation Platform (OSIP) – ESA’s place for your space ideas.

The technique involves looking at satellite navigation (GNSS) signals that have been reflected off of
