Sitting near the back of the Science Museum is a full-size model of a spacecraft that’s currently on a journey to Mercury. BepiColombo is a collaboration between the European Space Agency and the Japan Aerospace Exploration Agency, and its mission is to head to Mercury to study the planet’s surface and magnetic fields to learn about what lies beneath the surface.The spacecraft model is on semi-permanent display near the IMAX cinema at the back of the ground floor of the Science Museum. What’s impressive is the size of the spacecraft – these are really huge machines and putting then on display is a good way of reminding us that not everything in science is the study of the very small these days. There’s still some big machine engineering available.The BepiColombo spacecraft’s own 7-year journey to Mercury is designed to slow it down from the speeds originally needed to leave earth’s orbit, so it will use the gravity of three planets to slow it down. It will pass Venus twice, come back past Earth once — in April 2020 — and pass Mercury six times before it’s slow enough to be captured by Mercury’s weak gravity and go into orbit. -- ???????? | |||
