In the early 2020s the Euclid space telescope will be launched. From the second Lagrangian point in far Earth orbit, it will survey the full extragalactic sky. The mission's goal will be nothing less than understanding the dark universe. This talk will overview Euclid's main scientific goals. It will review the tools we are building that will enable us to probe the expansion history of our universe as well as the nature of gravity. As a Stage IV dark energy mission, Euclid will no longer be limited by statistics as much as it will be challenged by systematics. This talk will discuss some of those challenges and present some recent updates on how these challenges are being tackled. Finally, it will present the most up-to-date forecasts for some of the main cosmological parameters that we will use to constrain our cosmological model.
