After months of work, we are inviting you to join us and discover remarkable stories from some of the 7 million items we care for in the Science Museum Group collection.
The name Jedi Helmet was inspired by the Jedi knights in Return of the Jedi – the Star Wars film released in 1983 – and was used to encourage children (and adults) to wear the helmet and not be frightened during an MRI scan.
MRI (Magnetic Resonance Imaging) uses high frequency radio waves to build up a picture of the human body and help doctors diagnose illnesses. The copper coils on the helmets are aerials which can pick up the radio waves and improve the quality of the scan.
MRI is often used as it does not expose the body to radiation (unlike when you have an X-ray scan). It’s also better than X-rays for studying the body’s soft tissues (such as internal organs).
These Jedi Helmets were used in an MRI machine at Hammersmith Hospital in the 1980s. That machine was the first of its kind installed in the UK and one of the longest serving MRI machines in the world. The machine was removed in 1992 and is now part of the Science Museum Group collection.
The chair’s software would be changed according to the training requirement. The remote manipulator arm or ‘Canadarm’ was an articulated grabber used to deploy or retrieve satellites from the Shuttle’s payload bay.
It was famously used on the deployment and servicing missions of the Hubble Space Telescope. Astronauts, attached to the end of the arm, could also be positioned around the Shuttle to assist or to perform other operations outside the Shuttle.
The chair hand control on the left simulated control of the grabber (or “end effector”) so it could grapple or release items, while the rotational hand control on the right mimicked control of the pitch, roll, and yaw of the “wrist joint” near the end of the arm.
Using different software, this same chair was used to simulate the use of thrusters to manoeuvre the Shuttle for docking. This first occurred during the STS-71 mission in 1995, when the Shuttle Atlantis docked with the Russian space station Mir.
Further episodes will be added to this blog post as they are published.
