Monica Mary Grady CBE (born 1958) is a leading British space scientist, primarily known for her work on meteorites. Since 2005, she has been Professor of Planetary and Space Science at the Open University, and is currently Head of the Department of Physical Sciences.
Prior to 2005, Grady was based at the Natural History Museum in London, where she curated the UK’s national collection of meteorites. She graduated from the University of Durham in 1979, then went on to complete a Ph.D. on carbon in stony meteorites at Darwin College, Cambridge in 1982. Since then, she has built up an international reputation in meteoritics, publishing many papers on the carbon and nitrogen isotope geochemistry of primitive meteorites, on Martian meteorites, and on interstellar components of meteorites. She gave the Royal Institution Christmas Lectures in 2003, on the subject “A Voyage in Space and Time”. Asteroid (4731) was named Monicagrady in her honour.
Grady was appointed Commander of the Order of the British Empire (CBE) in the 2012 Birthday Honours for services to space sciences. She is the first UK scientist to be President of the international Meteoritical Society.
