Zita Martins (born 1979), OSE, is a Portuguese astrobiologist, and an Associate Professor at Instituto Superior Técnico. She was a Royal Society University Research Fellow (URF) at Imperial College London. Her research explores how life may have begun on Earth by looking for organic compounds in meteorite samples.
Early life and education[edit | hide all | hide | edit source]
As a child, Zita Martins studied classical ballet from the age of four and was encouraged by her teacher to progress to the National Ballet School in Portugal, which would have put her on track to become a professional dancer. Instead, at the age of 15, she decided she wanted to pursue science, gave up ballet and taught herself Russian. At secondary school, she filled in a careers test, which advised her strengths were in science and art, which Zita Martins says wasn't very helpful.
As an undergraduate studying chemistry, Martins was unsure how to direct her education towards a career in space science. She says, "I emailed NASA and asked them what I should do. They told me to do an internship in the Netherlands. I did an internship there, and did a really cool project analyzing samples from space (i.e. meteorites). I thought: ‘this is cool; I want to do this for the rest of my life’.
She was awarded a PhD in 2007 for Chemical analysis of organic molecules in carbonaceous meteorites from Leiden University supervised by Pascale Ehrenfreund. While completing her PhD, she gave a talk which was led to an invitation to be an Invited Scientist at NASA.
Research and career[edit | hide | edit source]
In 2013, Zita Martins, working with colleagues from the University of Kent shot steel projectiles at ice samples, which simulated the composition of comets to find out if their impact is responsible for the production of complex organic molecules. The experiment found that the impact-shock of a comet produces a number of amino acids, which are the building blocks of proteins. This has implications for the origin of life on Earth but also potentially in the icy moons of Jupiter and Saturn.
Committed to inspiring the next generation of young people to take an interest in science, Zita Martins has an active involvement with the international media. She is a BBC Expert Women Scientist.
