Since its establishment more than 30 years ago, the NASA Balloon Program has provided high-altitude scientific balloon platforms for scientific and technological investigations, including fundamental scientific discoveries that contribute to our understanding of the Earth, the solar system, and the universe. Balloons have been used for decades to conduct scientific studies. They can be launched from locations across the globe and are a low-cost method to carry payloads with instruments that conduct scientific observations. Recent developments in balloon design have allowed greatly extended flight durations, the current NASA target being 100 days aloft. Since 2017 Wanaka Airport has been a launch site, one of only seven world wide, uniquely positioned to capture the southern skies along latitude 45 south. This talk will describe both the balloon design and some of the science payloads carried and proposed.

Solar panels that convert light directly into electricity have come a long way since the discovery of the photovoltaic effect in 1839. Now, silicon-based solar panels are widespread, efficient, and cheaper than ever. However, for the world to meet its climate targets, we will need to generate a lot more solar power than we currently do – by 2030 we need to increase generation to at least ten times more than 2020 levels. New solar technologies could help us greatly in this energy transition. So what does the future of solar power look like?

In this talk I will give a brief history of solar technology. I will describe how solar panels currently work, and give an overview of where today’s cutting-edge physics, chemistry and materials science will lead us in the next few years. I will show how the work I am doing at Victoria University of Wellington will lead to the next generation of new solar panel materials, and talk about the creative ways materials scientists and device physicists will utilise our findings to create more tools for getting to a zero carbon future.

This paper summarises research over the last fifty years which has clarified what we now know about:

The  original discovery of the Chatham Islands,
The indigenous development there of Moriori population, culture and society,
The nature of Moriori society as it was prior to new arrivals,
The demographic, environmental, social and cultural impacts of rediscovery by sealers and whalers, and the enduring occupation of the islands by new settlers.
The condition of Moriori by 1870.

It reviews the Moriori struggle for survival which was set in motion by the herculean efforts and tactical genius of Hirawanu Tapu (1824-1900) and codified, a hundred years after his death, by settlement with the Crown.
