New Zealanders are being asked to rid themselves of data, from student loan invoices and divorce papers to unwanted photos, to help a mini satellite fly higher. The TWOi 2.0 measures just 2cm x 2cm and after being launched into space, is busy transmitting metadata to a receiver in New Zealand, in the name of art. The satellite's journey started back in November aboard a resupply mission to the International Space Station. It's been launched into space - two weeks ahead of schedule but when NASA says go, you go! The TWOi 2.0 is part of artist Julian Priest's mission to encourage people to rid themselves of excess data. Julian is Experience Wellington's latest Artist-in-Residence, based in the city's Thomas King observatory hosting "meet2delete" events. Lynn Freeman asked Julian how the project came about.
