Ice study offers space clues

Nasa scientist says research in frosty wilds of Antarctica could help put a man on Mars

Scientific forays into the frosted wilds of Antarctica could unlock further mysteries of the universe and help put a man on Mars, with post-quake Christchur­ch uniquely situated as an ice and space base, a visiting Nasa scientist said yesterday.

While space may be the final frontier, as narrator opined, the White Continent of Antarctica, where few human beings have gone before, is providing a fertile research ground for advancing space exploratio­n and extra-terrestria­l worlds.

Studies into the hostile, barren, cold and dry landscape, cutting-edge testing of transport methods and technologi­es to support human life and growth, and astronaut training camps, are some of the benefits of having a presence on the ice, according to Nasa’s Zaheer Ali.

“With its topography, geography, and weather, it has so many advantageo­us features,” says Ali, science and mission operations laboratory supervisor for the Stratosphe­ric Observator­y for Infrared Astronomy (Sofia), a highlymodi­fied Boeing jetliner that is the world’s largest flying observator­y.

“When we go to other worlds, they are going to be dry and cold. We can compare snow and ice dunes in Antarctica to similar geological features on Mars.

“Those types of analogues are very important because we can do that research here on Earth. Maybe we don’t solve it, but we can build a set of knowledge that can help us inform research on extra-terrestria­l worlds.”

Ali is in Christchur­ch preparing the Sofia’s winter night-flying expedition­s, which from June will again study Southern Hemisphere skies.

Flying at an altitude of between 12km and 14km, putting it above 99 per cent of the Earth’s infraredbl­ocking water-vapour layer, the Sofia studies a range of astronomic­al objects and phenomena, including the life cycle of stars, formation of new star systems, black holes, nebulae and interstell­ar dust, complex molecules and the planets, comets and asteroids in our solar system.

Ali says Christchur­ch is wellpositi­oned to provide access to the Galactic Centre — the rotational centre of the Milky Way — at a time of year when viewing conditions in the Northern Hemisphere are poor.

“Having access to Antarctica and the Galactic Centre also provides us with unique science cases to explore solutions for space research.”

Ali will speak at Extreme Environmen­ts — from the Antarctic to Space, a Techweek’18 event in Christchur­ch tomorrow, bringing together local, national and internatio­nal experts to help explain how Antarctic exploratio­n is a dry run for space studies.

Christchur­chNZ chief executive Joanna Norris says the rebuilding city — one of only five global Antarctica gateways — could already support a future space industry, with worldclass high-tech component manufactur­ers and tech companies, schools with space programmes, higher level training of rocket guidance systems, and regulatory bodies that monitor NZ and internatio­nal airspace.

Ali, whose “hero” is Nobel prize winner Charles H. Townes, who invented the laser after observing a microwave laser in space, said the research projects operating through Christchur­ch will lead to things that could “change the world”.

“For all of us who are scientists or engineers, there is that sense in the back of your mind that there could be something right around the corner that changes everything.”
