Contact is the SKA magazine. Published by SKAO's Communications team, the magazine brings together articles from scientists, engineering, design and construction teams, related facilities and telescopes and government partners. In this issue of Contact, we take stock of the big push towards starting construction at the telescope sites in the southern hemisphere next year. Science and art are not often mentioned in the same breath, but this issue illustrates how well they can go together. You can also enjoy depictions of radio astronomy telescopes on postage stamps around the world to celebrate World Post Day. As for science, the results of the second Science Data Challenge are in. We also review how galaxies evolve and what astronomers hope to discover as part of this SKA science goal. Enjoy!
