Direct Entry Job Permanent Harwell, UK

Uploaded 28 Nov 2018

Job Description

We now have a vacancy within RAL Space for either full time or part time team member to produce and fit the thermal insulation blankets that are used to protect satellites and their equipment in space.

Our Multi-Layer Insulation (MLI) blankets are hand-made from sheets of reflective material, often with netting to separate the layers. The design and folding of the blankets allow them to fit around space hardware, even if they have a complex shape. MLI blankets are used on almost every satellite that is launched and are critical in protecting from the cold of space.

You will be responsible for:

  • defining the shape of the blankets to fit hardware
  • working in a cleanroom to manufacture the blankets
  • packing completed blankets
  • helping to fit blankets to spacecraft and instruments
  • carrying out basic stock control of materials and parts.
  • MLI blanket manufacture requires particular care, attention to detail and patience. You will be required to follow written and verbal instructions to ensure that the blankets are manufactured to specification.
