take a deep breath and blow - large led sign

The shuttle carried an unusual payload into orbit.
It's not just a box with a polymer film, a compressed nitrogen bottle, a camera and a large LED display, it's what NASA calls a first-class device
A high-risk enterprise, if successful, will bring huge potential benefits.
On the second day of the mission, gambling began as the shuttle flew with its opentowards Earth Bay.
The crew put the box out and then manipulated the cabin to watch it around a hundred metres.
At the beginning of the experiment, the box was opened and the sheets carefully folded were sprinkled into space.
Next, nitrogengas began to force into the material and a complex structure began to take shape.
First, the three pillars begin to wave awkwardly, and then form a trilegged animal whose vertices are still attached to the box.
At the free end of the triangular leg, a huge ring unfolds with an empty inflatable discus in it --
Shaped balloon 15 m wide
The side of the balloon closest to the box, but the inner surface of the other side, be careful
A disk in the shape of a metal coating.
The invisible package that came out of the box has become a huge radio antenna, as big as a spaceship.
To make matters worse, the plan is to use the light pattern generated by the LEDs installed in the box to check the irregularities in the parabola.
