There aren’t many people with an asteroid named after them. Monica Grady has Asteroid 4731, aka ‘monicagrady’, named after her.
Monica is a Professor of Planetary and Space Sciences at the Open University. Monica spoke at the London International Science Forum this year, and we talked to her to find out what she studies.
“The research I do is to try and understand the origin and evolution of the solar system and I do that by studying extra-terrestrial materials such as meteorites, pieces from the moon and mars and I also use data that have come from space missions such as the Rosetta Mission.”
“I work on all sorts of things! Yesterday I was working on a proposal to get money to study samples from the moon. I have also been studying data from Rosetta looking at material from the comet. But most of all I study meteorites and the things inside which tell you about the origins of life on earth.”
“What’s really impressed me about LIYSF is the fact that you have such an enormouse number of students from all around the world who are meeting with one another, talking to each other and interacting on projects in teams. They’re making friendships which will last way beyond this forum.
I think it’s really important for young people to get into science because that’s the future for us and what we need. Whether you’re looking to become a teacher, a plumber, an engineer or a doctor, it doesn’t matter because you need to understand how the world around us works, even if it’s how to use the new Pokémon Go app!”
“We need more people studying STEM subjects, because the world hasn’t got enough scientists and engineers to staff all of the industries that need them. If only men do all of that, it’s ruling out 50% of the population, women can do science and engineering as well as, if not better than men. STEM isn’t about lab coats and greasy overalls, it is about doing exciting experiements , being in front of computers and modelling data: women are perfectly capable of doing this and we need everyone we can get.”
Monica studies asteroids and comets by analyzing small pieces from meteorites in her laboratory, in order to understand processes that led to the evolution of life on earth.
The 67P/Churyumov–Gerasimenko is a comet that Monica has been involved in with on the Rosetta mission and the European Space Agency, aimed at getting Rosetta’s lander (Philae) onto the surface of the comet. When it landed in November 2014, it was the first spacecraft to land on a comet and Monica’s team were able to take samples of the comet.
Early results found that the surface of the comet was incredibly dense, although beyond the outer layer, Monica described the interior resembling a ‘fluffy ball’! By looking at the ratio of deuterium to hydrogen in the water from the comet, the team were able to rule out the hypothesis that water found on earth comes from comets.
Monica also compared 67P to a rubber duck!
The European Space Agency put together an informative cartoon summarizing the Rosetta mission, which was shown to LIYSF participants:
The LIYSF participants were left astounded (but not speechless!) as Monica concluded her session on the Rosetta mission.
Reflecting On Women in STEM – Part Three: Reflecting Back, but Looking ForwardThis three-part blog series aimed to explore, highlight, and celebrate women in the field of Science, Technology, Engineering and Mathematics (STEM). As the final blog for this series, it provides a glimpse of what a future driven by women looks like and celebrates the up-and-coming women who are making strides in...

A three part-series A Glance at Women in STEM Science, Technology, Engineering, and Mathematics (STEM) is a rapidly advancing field and one that is essential to the future and survival of our society. However, not everyone is equally acknowledged or celebrated for their involvement. Historically, and still to this day, women are disproportionately represented in the STEM workforce. While the nu...
