CubeSat
큐브위성
A very small satellite built from a basic unit: a cube 10 cm on each side.
Overview
CubeSats follow a set standard, so they can be put together from bought parts. The basic unit (1U) fits on the palm of your hand, and several can be joined to make a bigger one.
They ride along in the spare room when a large satellite launches, so they are cheap. Universities and small companies can now launch their own satellites. They are also flown in groups to photograph Earth often.
An everyday example
It is like putting a small parcel on a big cargo ship. You do not have to rent the whole ship.
Why it matters
It lowered the barrier to entering space. It gives a cheap way to test new technology, and many space companies started with CubeSats.
