Video Title:  GAO: Large Constellations of Satellites Technology
Assessment

Narration
For decades, satellites have been used for GPS, communications, and
remote sensing. More recently, "constellations" of a hundred satellites
or more have been used to provide internet access-which helped drive a
dramatic spike in the number of satellites in orbit.

- about 5,000 in orbit as of 2021
- 60,000 expected by 2030

Narration
We talked to experts and federal agencies and they said satellite
constellations could have some disruptive effects.

For example: Chemicals from the rockets that propel satellites into
space could deplete ozone and lead to unexpected changes in the climate.
Light reflections and radio transmissions could make it harder for
astronomers to spot asteroids and study the universe.

And, each new satellite raises the risk that a collision or failure will
create more space debris, which could endanger other satellites, crewed
missions, and people on the ground as it falls back to earth. To find
out how policymakers could address these and other challenges at G-A-O
