Very sad
It's very sad to hear that Lester is no longer with us.
It was a pleasure to show him and Matt around our site at the European Space Agency last year.
The sight of them walking around with white lab-coats and whipping a playmobil astronaut out in the satellite control room definitely caused a chuckle for the resident rocket scientists.
