ALUMNI FOCUS

2018 Macquarie University Alumni Awards – Dr Abigail Allwood

CATEGORY: SCIENCE AND TECHNOLOGY

Is there life on Mars? It’s a question many ponder, but few are qualified or engaged to answer this timeless question. That is, unless you are Dr Abigail Allwood, first female and one of seven principal science investigators to lead NASA’s next mission to Mars, scheduled for 2020. She will also be the first Australian to lead a NASA team searching for signs of life on Mars, and she hopes that this exceptional achievement will light a path for other women.

To be part of NASA’s next mission to Mars, Allwood and her team pitched the inclusion of the Planetary Instrument for X-ray Lithochemistry, or PIXL for short, a NASA-funded instrument that scans rocks for chemical signatures of life. To Allwood and her team’s delight, she was accepted.

PIXL will be operated remotely from Earth and will be able to analyse specimens in greater detail than ever before. But Allwood is no stranger to Martian life. As an early-career academic, she explored Australia’s Pilbara for signs of life from Mars. It took three years, but she and her husband identified seven different-shaped fossil stromatolites that date back 3.4 billion years.

Given the number and range of specimens, even those most sceptical were in no doubt of the validity of her discovery, and it is still the oldest – and most widely accepted – record of life on Earth. But this was not the end of the story. Allwood won a coveted position at the California Institute of Technology, where working under geologist John Grotzinger (lead scientist for the 2014 Mars Curiosity rover) would become a key link in her own Mars expedition.

Allwood began developing PIXL by reducing the size of a similar instrument used in the Pilbara and waited for her dream to be confirmed – PIXL would be going to Mars.

One small step for PIXL. One giant leap for womankind.

Dr Abigail Allwood, astrobiologist and co-leader of NASA’s Mars 2020 rover mission, has a strong interest in the early Earth, microbial sediments, evaporites and the oldest record of life on Earth, and has been outspoken on the need to invest in – not cut – funding for the sciences in Australia.

Allwood graduated from Macquarie with a PhD in Earth Science (2007).
