The Australian avionics systems engineer who helped build, test and launch the Rosetta space craft that successfully landed a probe on a comet (Comet-67P) last year will give a free public lecture at the University of Waikato this week. Warwick Holmes spent 29 years working on European Space Agency spacecraft projects and missions including four and a half years on the Rosetta project. He thinks New Zealand and Australia should be investing much more in science and engineering.
