Sounds from Space

 

Sounds from Scientific, Meteorological and Commercial Satellites 2017-today

This part of my audio collection is dedicated to commercial and scientific satellites. I started this separate section when Greg Roberts, ZS1BI in Cape Town, started to convert some of his old recordings from a tape recorder with elastic belt drives to electronic format. Greg is a retired professional astronomer and since 1957 has been actively involved in the tracking of artificial satellites, both by optical and radio means. Click on his picture to the right to get more information about him and his activities.
