An image to illustrate the Postgraduate Diploma in Space Science and Technology
This postgraduate qualification is for those with an academic or professional interest in space science and the technology that underpins this discipline. It equips you with the skills to conduct scientific investigations using space-based instrumentation, individually and as a team. You’ll also learn how to use a programming language for space science applications and develop other skills highly relevant to employment in the space sector. You can choose option modules from applied mathematics, computing and IT, engineering, environmental management, physical sciences, project management and systems thinking.
This postgraduate diploma is the same as the first two-thirds of our MSc in Space Science and Technology (F77). The first half is the same as our Postgraduate Certificate in Space Science (K28).
To gain this qualification, you need 120 credits. You'll study a compulsory 60-credit space science module and choose 60 credits from a range of option modules.
