Remote experiments in physics and space

This is a practical science module with astronomy, physics and planetary science activities. It builds on your previous study, adding a vital element of experimental work. The investigations cover aspects as diverse as quantum mechanics; properties of electrons; planetary atmospheres and surface processes; and clusters of stars in the Milky Way. You’ll use remote equipment ranging from infrared and X-ray spectrometers to an optical telescope in Tenerife. You’ll build your experience and expertise in practical investigation, including observation, hypothesising and reporting skills. In addition, an exciting project develops team-working skills critical to collaborative scientific enquiry.

Modules count towards OU qualifications

  • Credits measure the student workload required for the successful completion of a module or qualification.
  • One credit represents about 10 hours of study over the duration of the course.
  • You are awarded credits after you have successfully completed a module.
  • For example, if you study a 60-credit module and successfully pass it, you will be awarded 60 credits.

Study level

Across the UK, there are two parallel frameworks for higher education qualifications, the Framework for Higher Education Qualifications in England, Northern Ireland and Wales (FHEQ) and the Scottish Credit and Qualifications Framework (SCQF). These define a hierarchy of levels and describe the achievement expected at each level. The information provided shows how OU module levels correspond to these frameworks.

What you will study

You’ll conduct all the live experimental investigations remotely. This parallels the way many modern scientific investigations are conducted. It’s no longer necessary to travel to a remote mountaintop to use the latest telescope – you can book time and control equipment remotely. The same applies to a particle accelerator or other major scientific installations. Space-based explorations such as a space telescope or Mars rover are operated remotely. The remote experimentation skills you’ll develop are directly relevant to finding employment in the space sector.

Cooperation and group work are also characteristic features of scientific investigations. Large-scale enterprises like the Large Hadron Collider or the Mars Curiosity rover can operate only if many people work together. By working with fellow students and supported by research experts, you’ll achieve more than any one person working alone. You’ll develop vital employability skills in communication, collaboration and professional team working.

There are three main investigations – covering astronomy, physics, and planetary science:

Astronomy: Exploring the Milky Way
In this investigation, you’ll use an optical telescope (PIRATE) to investigate the properties of star clusters found in different parts of our galaxy, the Milky Way. You’ll obtain optical photometry in two wavebands of open and globular clusters of stars, from which you’ll compile colour-magnitude diagrams to estimate properties such as the ages and distances of the clusters.

You’ll typically work in a group with four other students, supported by experts in optical astronomy and the use of robotic telescopes.

You must choose from the two options (Observer mode or Queue-scheduled mode) at the start of the module. We’ll provide complete descriptions of both modes and a discussion forum to help you choose. Places for Observer mode may be limited, so book early to maximise your chances of getting an observing session if this is your preferred choice.

Physics: Electron–photon interactions
This activity, about charged particles and radiation, is split into two investigations.

In the first investigation, you’ll use an interactive screen experiment (ISE) to measure the deflection of a beam of electrons in a magnetic field. You’ll use this to measure a fundamental property of the electron – its charge to mass ratio.

The second investigation is a live experiment in which you’ll use apparatus in a lab at the OU campus using remote control software. You’ll investigate the process of Compton scattering – the interaction of X-ray photons with individual electrons. During your studies of the Compton effect, you’ll be recreating a Nobel Prize-winning experiment and confirming a fundamental result in quantum mechanics.

This activity will develop your skills in conducting practical investigations including calibration of equipment, handling of experimental errors and the presentation and interpretation of results.

Planetary science: Mars atmosphere and surface
This investigation is centred around an imagined space mission to Mars. In the first phase you’ll carry out a live experimental investigation using infrared spectroscopy to determine properties of planetary atmospheres. You’ll be making use of technology designed by researchers at the OU and flown on actual space missions.

The second part of the investigation concerns planetary surface processes. Using genuine Mars data, you’ll learn how to process and extract information from public domain datasets. You’ll use this to model processes such as the production and evolution of the atmosphere and surface features of another planet.

Team project
Towards the end of the module, you’ll complete a short team-based project involving the design of a future space mission. This activity will build on your knowledge of experimental design, instrumentation, and team working. You’ll work collaboratively with your team using a variety of communication methods, including scheduled online forums.

You will learn

The practical skills developed in this module include:

  • experimental technique and experimental design
  • planning and conducting observations and experiments
  • data handling, including computer programming for data analysis
  • data presentation
  • report writing
  • safe working
