As Catalonia launches its first nanosatellite, science writer and educator Joan Anton Català Amigó joins the Filling the Sink team to talk all things space. 

Catalan Digital Policies minister Jordi Puigneró defends the formation of the Catalan Space Agency and explains that it's clearly not "a Catalan Nasa." 

Alan Ruiz Terol takes a visit to Montsec Observatory and Astronomical Park in western Catalonia, where the nanosatellite – named Enxaneta – will be controlled from after taking off from the Baikonur Cosmodrome in Kazakhstan. 

And with Nasa's Mars Perseverance rover toiling away on the red planet, Dr Carolina Arnau Jimenez tells Cristina Tomàs White how the European Space Agency's research at the Autonomous University of Barcelona could pave the way for humans to follow suit in the future.
