Last year, Nikol Posnov told us about all the things that she was planning to study as an Earth Science MSc student. This time, she's returned to tell us about what she actually ended up researching. What can rocks taken from Brazilian impact craters tell us about where we might find evidence of life on Mars? How likely is it that future missions will find anything living on the Red Planet? On this episode, hosts Yimin and Yousuf ask these hard-hitting questions and more: like, "what's your favourite movie alien"? The answer may surprise you!

To find out more from Nikol, follow her on Twitter @SpaceDoctorNik or follow her supervisor @DrCrater
