The ESA (European Space Agency) Euclid telescope, with contributions from NASA, is shown here on Friday 23 June, being secured to the adaptor of a SpaceX Falcon 9 rocket before launch. Black solar panels line the right side of the spacecraft. The telescope will view the cosmos through the top of the white cylinder that sits above the spacecraft's instruments. https://photojournal.jpl.nasa.gov/catalog/PIA25783
