UCL Department of Space and Climate Physics


Mullard Space Science Laboratory

MSSL is a world-leading space science laboratory. Based in the Surrey Hills near Dorking, MSSL has been developing cutting-edge space research and space technology for over 50 years. Our research covers all aspects of space research, from understanding the Sun and its interaction with the planets, to understanding galaxies and the matter that makes up the universe. We build and operate cutting edge space hardware for multinational space missions. We also offer state-of-the-art test facilities for ground and space-based technology.


Covid-19 Arrangements: 23 March 2020

In line with UCL policy, the Department has now moved to on-line working. The Holmbury House and Taviton Street sites are now closed to all but a very few staff who may visit in order to keep essential functions operating, for example to support remote working.

We have made arrangements to continue our daily research, teaching, engineering and management activities and we expect that these will largely continue. Staff will be contactable as usual during working hours via email, video and teleconferencing. In particular the general office (office@mssl.ucl.ac.uk) will be available to answer queries. For internal advice to staff and students regarding COVID-19 arrangements, please visit the Departmental Intranet: https://www.ucl.ac.uk/mssl/intranet.   

All teaching has moved online for the remainder of this Term and Term 3. Students should continue to contact tutors as normal, as well as our Taviton Street teaching admin team, either directly or via Moodle. The UCL online application process for prospective students also remains fully open.

We are embracing a broad range of online platforms, and look forward to the new opportunties for interaction that they will bring!
