On 30 June, the European Strategy Forum on Research Infrastructures (ESFRI) decided to include the Einstein Telescope (ET) in the update of its roadmap for 2021. This is a great result achieved thanks to the work of many actors: a group of visionary scientists who started thinking about the 3rd generation of gravitational wave detectors in 2004, the team that realised the ET concept design in 2011 and updated it in 2020, the ET Steering Committee, the institutions that signed the ET Consortium Agreement, and the governments that presented and supported the ET proposal for the 2021 update of the ESFRI Roadmap.

 The inclusion of ET in the ESFRI Roadmap is an important milestone, but mainly a starting point for the realisation of the Einstein Telescope Gravitational Wave Observatory. The entire community interested in ET has clear goals that it will now pursue with even more momentum: finalising the ET technical design, selecting the ET site, further defining the science of ET and the 3G network of GW observatories, developing the ET technology to installation readiness, optimising the tools for data analysis and the scientific use of ET.  All together, we need to attract a larger scientific community, a broader consortium of agencies and institutions, and stronger support from our governments for ET. On a global scale, we also need to exploit synergistic effects and strive for a harmonic relationship between the various gravitational wave projects.

 Tomorrow starts today! Let's work together on ET!
