Proba-3 is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3’s Coronagraph spacecraft observe the Sun’s faint surrounding atmosphere, the disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3’s Occulter ends up facing the Sun continuously, making it a valuable platform for science in its own right. View the full article

Torrential rainfall causing deadly flash floods has hit southern and eastern Spain in regions including the Costa del Sol, where the city of Malaga is located, and Valencia in the east. As these areas struggle to cope with the aftermath, satellite technology has played a crucial role in assessing the damages of the affected areas. View the full article

When disaster strikes, maintaining communication is critical. Yet, terrestrial (ground) networks are often compromised, leaving civilians stranded and first responders without access to vital information. Limited bandwidth can severely delay crisis management efforts, potentially costing lives. Recent events around the world, including devastating floods and wildfires, underscore the increasing relevance and urgency for advanced disaster response technology. View the full article

Stare deeply at these galaxies. They appear as if blood is pumping through the top of a flesh-free face. The long, ghastly ‘stare’ of their searing eye-like cores shines out into the supreme cosmic darkness. View the full article

ESA’s solar eclipse-making Proba-3 mission is about to leave Europe, to head to its launch site in India. The mission’s two spacecraft – which will manoeuvre precisely in Earth orbit so that one casts a shadow onto the other – have departed the facilities of Redwire Space in Kruibeke, Belgium. The pair will be flown to the Satish Dhawan Space Centre, near Chennai, for the launch campaign to begin. View the full article

Image: The construction phase of ESA’s Ariel mission has started at Airbus Defence and Space in Toulouse (France) with the assembly of the spacecraft’s structural model. This marks a significant step forward for this mission designed to meticulously inspect the atmospheres of a thousand exoplanets and uncover their nature. In the image we see Ariel’s structural model coming together at the Airbus facilities. This model replicates the mechanical framework of the spacecraft and the mass of its various units for a first round of tough testing. The Ariel’s structural model consists of two main components: a flight-like replica of the service module (bottom right) and a simplified mechanical mock-up of the payload module (top right). This assembly mimics the structure of the flight spacecraft, where the science instruments make up the payload while the service module houses the essential components for the functioning of the spacecraft, such as the propulsion, and the power and communication systems. The goal for the end of the year is to complete the mechanical test campaign of the spacecraft’s structural model. This will ensure that Ariel’s design is up-to-spec and can withstand the mechanical strains expected during launch. The testing phase will include vibration and acoustic test campaigns. During vibration tests the model will be progressively shaken at different strengths on a vibrating table, or 'the shaker'. During acoustic tests, it will be placed in a reverberating chamber and ‘bombarded’ with very intense noise, like it will encounter during launch. This model will also be used to assess how the loads are distributed and to perform a first ‘separation and shock’ test using the same mounting system as will be used to mount the spacecraft on the Ariane 6. When ready, Ariel will be launched by an Ariane 6.2 rocket and journey to the second Lagrangian Point from where it will carry out its uniquely detailed studies of remote worlds. Image description: A collage of three photographs that show the assembly of the model of a spacecraft in a large white hall. The first image on the left shows the entire model, with a person next to it who is nearly equal in height. The second image on the upper right zooms in on the top part of the mock science instrument: a circular fan-like structure with a big rectangular silver box on top. The third image on the lower right focuses on the bottom of the model, which looks like a large round silver box. View the full article
