In July of 2006, scientists at Russia’s Plesetsk Air
Base were busy preparing the satellite Arirang-2 for launch. Then an
80-year-old lady appeared with a sewing basket. The lady
opened the basket, threaded a needle, and started to sew, stitch by stitch. This
lady had 50 years’ experience of such work since the world’s first satellite. She was making a gold dress for the
satellite.
This was no ordinary dress, though. Known as multi-layer insulation (MLI),
it was designed to protect satellites from the hard conditions of space:
burning sunlight, cosmic debris, and temperatures as cold as -270°C.
The MLI had to be made by hand. This is because it had to fit around all
of the satellite’s shapes. While the MLI provides great
protection, its bright gold color also makes satellites the most brilliant
objects in the sky.
