Public Lecture: Life on Mars: Phoenix & Beyond

By leopardi - 19 September 2008 3

Speaker/Host: Professor Malcolm Walter
Venue: Manning Clarke Centre Lecture Theatre 1, ANU

NASA’s Phoenix lander has ‘tasted’ water on Mars. On Earth, where there is water below about 150 degrees centigrade, there is life. There have long been observations suggesting the presence of water on Mars, but now we have a direct analysis. Phoenix has also given us new information about the “soil” on Mars. There are oxidising compounds, but the soil has nutrients that could sustain life. It is comparable to the soils of the Atacama Desert in Chile, and there is certainly life there. The Phoenix lander discoveries provide further clues that microbial life could have existed on Mars. If it was once there, almost certainly it still is. If such proof could be uncovered then it would be possible to say something about the extent of life elsewhere in the universe. Does that mean we may, one day, find intelligence elsewhere among the stars? Australia has a unique role to play in the quest for life beyond Earth. This presentation explores what we are learning from Australia’s clues to the origin of life on Earth, and the connection to the latest results from Mars.

Professor Walter is a world expert on early life on Earth and its impact in the search for life elsewhere in the universe. He has worked extensively with NASA in helping to lay the groundwork for today’s exploration of Mars by robotic space probes, and in locating the geological circumstances for possible past and present life on Mars. He is Director of the Australian Centre for Astrobiology at the University of New South Wales.

This lecture is free and open to the public.
Refreshments will be served from 6-6:30pm.
This is an ANU Public Lecture in conjunction with the 8th Australian Space Science Conference.

Q: How does one become an Astrobiologist?

Shame that link doesn’t work.

It’s a god-awful small affair
To the girl with the mousy hair
But her mummy is yelling “No”
And her daddy has told her to go
But her friend is nowhere to be seen
Now she walks through her sunken dream
To the seat with the clearest view
And she’s hooked to the silver screen
But the film is a saddening bore
Though she’s lived it ten times or more
She could spit in the eyes of fools
As they ask her to focus on

Sailors fighting in the dance hall
Oh man! Look at those cavemen go
It’s the freakiest show
Take a look at the Lawman
Beating up the wrong guy
Oh man! Wonder if he’ll ever know
He’s in the best selling show
Is there life on Mars?

It’s on America’s tortured brow
That Mickey Mouse has grown up a cow
Now the workers have struck for fame
‘Cause Lennon’s on sale again
See the mice in their million hordes
From Ibiza to the Norfolk Broads
Rule Britannia is out of bounds
To my mother, my dog, and clowns
But the film is a saddening bore
‘Cause I wrote it ten times or more
It’s about to be writ again
As I ask you to focus on

Sailors fighting in the dance hall
Oh man! Look at those cavemen go
It’s the freakiest show
Take a look at the Lawman
Beating up the wrong guy
Oh man! Wonder if he’ll ever know
He’s in the best selling show
Is there life on Mars?
