 you know several petabytes of data so it's basically in terms of the number of sequenced molecules we have it's a tenfold increase in the publicly available data for many astronauts we also included some data from the nasa twin study as part of the data released from this big package of papers which was when scott kelly went in space for a full year and i was one of the principal investigators for that mission so we're really excited to start to compare between missions let's say a few days versus a few months versus a year
