It blows my mind to know that hundreds of satellites are whizzing around above me in near-Earth space. Now, for the first time, a satellite made in Scotland is in orbit.
The satellite was one of two UK-made craft launched last night from Baikonur in Kazakhstan aboard a Soyuz rocket. The satellites will study space weather, take images of Earth and research new ways of securing communication.
I'm fascinated by what can be learned about the Earth from space - and the more countries that have access to it, the better.
