In August this year NASA’s $2.5 billion dollar Curiosity rover landed inside Mars' huge Gale Crater where its mission is to determine if Mars has ever been capable of supporting microbial life.

This week NASA announced that Curiosity had discovered something in one of its soil samples however the space agency would need to double check its data before making an official announcement.

Since the initial announcement was made earlier this week people have been speculating on what NASA might have found and whether they will announce the discovery of alien life on mars.

2ser’s Rory O’Gorman spoke with Kerry Dougherty curator of space research at the powerhouse museum in Sydney for her thoughts on what NASA may be set to announce.
