Focus on Euclid with Jean-Charles Cuillandre: “What we see in the first Euclid images is a promise of what will come in the future.”

Jean-Charles Cuillandre, astronomer at CEA Paris-Saclay, explains that he was “blown away” when he saw the first full-colour images captured by ESA’s recently launched Euclid space telescope. 

Being a specialist of wide-field imaging, Jean-Charles was not only involved in the programme committee that selected the celestial targets for the ESA Euclid’s ‘Early Release Observations’, but he was also in charge of processing the data both for their scientific and their outreach value.

Jean-Charles expected the resulting images to look extremely crispy since they are taken by instruments outside of the Earth’s disturbing atmosphere, but even he was not prepared for the astonishing results. The combination of the field-of-view (the area of sky covered with a single shot of the telescope), and the resolution (the number of pixels in the instruments) are unique for Euclid.

The first five released images therefore show the scientific potential of the Euclid space mission. The Euclid Consortium is responsible to fulfill this promise. More than 2000 scientists from 300 institutes in 13 European countries, the US, Canada and Japan, will try to decipher the dark Universe through the analysis of Euclid’s scientific data.

In this interview, Jean-Charles Cuillandre shares with us his view of Euclid and the elusive dark matter and dark energy. He specifically describes the apparent astronomical objects and reveals the hidden information behind their beautiful appearance.

Be ready to be “blown away”.

Space Team Europe is an ESA space community engagement initiative to gather European space actors under the same umbrella sharing values of leadership, autonomy, and responsibility.

      How Europe’s biggest rocket came to be: Ariane 6 montage
      By European Space Agency
      Video: 00:08:21 The first half of 2024 saw hundreds of people across Europe building, cajoling, shipping, lowering, integrating, securing and protecting the precious pieces and parts that came together to create Ariane 6 – Europe’s new heavy-lift rocket.
      Huge engines, boosters and outer shells met tiny screws, electrical boards and masses of supercooled fuel. All this came together at Europe’s Spaceport in French Guiana, for the spectacular first launch of Ariane 6 on 9 July 2024, restoring Europe’s access to space.
      Get a glimpse at the teamwork, skill and care that went into this moment over many months, in this montage of Ariane 6 images, videos and timelapse photography spanning 30 January to 9 July 2024.

      Tech Today: Space Age Swimsuit Reduces Drag, Breaks Records
      By NASA

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.Credit: SpeedoUSA A supersonic airplane and a competitive swimmer have much more in common than people might realize; both have to contend with the slowing influence of drag. NASA’s Aeronautics Research Mission Directorate focuses primarily on improving flight efficiency and fluid dynamics, especially the forces of pressure and drag, which are the same for bodies moving through air as for bodies moving through water. Shortly after the 2004 Olympics, Los Angeles-based SpeedoUSA, also known as Speedo, asked NASA’s Langley Research Center to help design a swimsuit with reduced surface drag. The manufacturer sought a partnership with NASA because of the agency’s expertise in fluid dynamics.

      In competitive swimming, where every hundredth of a second counts, achieving the best possible drag reduction is crucially important. Researchers at NASA began flat plate testing of fabrics, using a small wind tunnel developed for earlier research on low-speed viscous drag reduction and collaborated over the next few years with Speedo to design the LZR Racer swimsuit.

      Researcher Corey Diebler inspects a model of the supersonic X-59 after a test in Langley Research Center’s 12 foot wind tunnel. Wind tunnel testing at Langley enabled Speedo’s LZR Racer to achieve its excellent underwater performance.NASA/David C. Bowman. NASA and Speedo performed tests on traditionally sewn seams, ultrasonically welded seams, and the fabric alone, which gave Speedo a baseline for reducing drag caused by seams and helped identify problem areas. NASA wind tunnel results helped Speedo create a bonding system that eliminates seams and reduces drag. The results also showed that a low-profile zipper ultrasonically bonded into the fabric inside the suit generated eight percent less drag in wind tunnel tests than a standard zipper. Low-profile seams and zippers were a crucial component in the LZR Racer, because the suit consists of multiple connecting fabric pieces—instead of just a few sewn pieces such as found in traditional suits—that provide extra compression for maximum efficiency.

      In March 2008, the LZR Racer made its mark on the world of competitive swimming. Athletes donning this innovative swimsuit shattered 13 world records, a testament to the power of collaboration between NASA and Speedo. While the original LZR Racer is no longer used in competition because of the advantage it gave wearers, its legacy lives on in today’s swimsuits approved by World Aquatics, the governing body for international competitive swimming.
