Dr. Dish shares his fascinating factoids about NASA’s Deep Space Network.
How big is an antenna?
Dr Dish here! Did you know the 70-meter antenna dish is almost as big as a football field?
What can a DSN antenna do?
Dr. Dish here! Did you know that the Deep Space Network, using only three antennas, can non-stop track any spacecraft between our moon and the very edge of the solar system?
Why do you need a big antenna?
For a spacecraft in Earth orbit, like the ones people use to get TV shows, you need only a small dish.
If that satellite were at the moon, hundreds of thousands of miles away, you'd need a dish as big as a two-story house!
And if it were millions of miles away, like Mars or the other planets, you'd need a dish that's ten times that big - like the ones at the Deep Space Network!
