Each weekend, we’ll sort out your plans for you. These are the things we think you should browse, watch, read or do over the next couple of days. This weekend, get some ideas for stuff to do in Sydney, learn more about the holy grail of surfing, read about the future of space travel, watch the results of an iPhone strapped to a jet, see inside one of America's last pencil factories and hang out with Paris Verra as she travels the globe.
