A leading space scientist and star of a hit YouTube video visited an Ealing school on Wednesday (January 13) to offer up a lesson in meteorites.

Professor Monica Grady, who has worked with NASA and the European Space Agency, gave children at William Perkin School, Greenford , Ealing, a lesson in meteorites and terrestrial rock.

The Open University professor made waves in 2014 when she featured in a YouTube video (below), showing her ecstatic response to the robot probe Philae landing on a comet.

Professor Grady spent over a decade working on the mission, as part of the Rosetta project, where she had worked on a gas analysis mission and it became the first ever spacecraft to land on a comet.

Year 7 pupil at the school Keshav Tuli, from Greenford, 11, said: "We were learning about the comets and it was really exciting because I felt like I was working as a scientist."

The professor gave the students the chance to assess the mineral content of Meteorites.

A sum of £3,000 has recently been given to the William Perkin Science Department as part of the Royal Society Partnership Grant.

The fee will enable 15 students from the school to work with Professor Grady in preparation for a poster presentation to be made to the Royal Society Conference, Open University, Milton Keynes.

It is also hoped by the school that a presentation will be made at The Imperial Festival 2016.
