The reduction of costs for a given performance is a major goal of spac
e systems technologists. Extreme miniaturisation, by reducing the leve
ls of resources required, is a possible solution. Micro/nano-technolog
ies allow the production of multiple types of microdevices and their i
ntegration into microsystems, resulting in application-specific integr
ated microinstruments. In recognition of their importance, ESTEC and I
ndustry held a Round Table on Micro/Nano-technologies for Space. Based
on the conclusions and recommendations made at the meeting, activitie
s are proposed to gradually introduce these technologies in space-base
d systems.
