Cosmology Data Center Finland (CDC-FI) facilitates Finland's participation in large international observational cosmology projects, such as the European Space Agency Euclid and LISA observatories, by providing in-kind contributions to these missions. Euclid is a wide-field space telescope that launched on 1st July 2023. Euclid will help solve the mystery of the accelerating expansion of the universe: is it caused by “dark energy”, or must the law of gravity be modified? LISA will be the first gravitational wave observatory in space. Gravitational waves offer a new window into the universe: LISA will see further than has been possible with optical or radio telescopes. Data from these missions will have a huge impact on cosmology and astrophysics, forming the basis for future research. Roadmap status will give CDC-FI the resources to cope with the peak in Euclid demand at the end of its nominal mission, and the growing needs of LISA in the run-up to launch.
