An example of the application of Yaffs in a demanding environment
NASA TESS Mission This Transiting Exoplanet Survey Satellite (TESS) will discover thousands of exoplanets in orbit around the brightest stars in the sky.
It is a project regularly using our Yaffs File System to store incoming data and preserve it, in the rigours of the space environment, before sending it back to Earth.
In a two-year survey of the solar neighborhood, TESS will monitor more than 200,000 stars for temporary drops in brightness caused by planetary transits. This first-ever spaceborne all-sky transit survey will identify planets ranging from Earth-sized to gas giants, around a wide range of stellar types and orbital distances. No ground-based survey can achieve this feat.
Some File Systems are not robust enough to be suitable for such exacting work.
