A rare live two way link with the Boulby Underground Laboratory, where the Boulby team will give us a tour of the underground facilities that include a Mars Yard, where real (and LEGO) Mars rovers are tested, multiple Dark Matter research experiments, understanding the radioactivity of substances and more! Have any questions you want answered? Email them to will.furnell@stfc.ac.uk Boulby is one of just a select few facilities in the world suitable for hosting ultra-low background and deep underground science projects. It is a special place for science, 'a quiet place in the Universe', where studies can be carried out almost entirely free of interference from natural background radiation. It also provides access & support for studies of the geologically interesting deep underground environment. We are employees of the Science and Technology Facilities Council, the UKRI research council that runs the facility.
