The Super Guppy, Middle school

NASA's Super Guppy cargo plane lifts off from Ellington Field in Houston, its giant round body bulging above the wings

Some rocket parts are 15 to 20 feet wide. They’re too big for regular cargo planes. They’re also too fragile for a long, bumpy ride down the highway.

Could a plane carry a rocket part that big inside its body?

Have you heard of the Super Guppy?

The Super Guppy is a NASA cargo plane with a giant round body. NASA uses the plane to fly rocket and spacecraft parts that are too big for regular cargo planes and too fragile for long trips on bumpy highways. Aerospace engineer Naia Butler-Craig talks about the plane in the video.

Your word of the day is

air-uh-NAW-tiks

aero-airfrom Greek āḗr
naut-shipfrom Greek naûs
-icsa science or field of studyfrom Greek -ika

The design, construction and operation of aircraft, and the study of flight through the air.

On the ground, giant rocket parts run into tunnels, narrow roads, low bridges and power lines.

How does the Super Guppy get giant rocket parts past tunnels, bridges and power lines?

Some rocket parts are too fragile for potholes. The trip to the launch site can be thousands of miles.

What makes a long highway trip so risky for a fragile rocket part?

The Super Guppy swings its whole nose open on the ramp at NASA's Dryden Flight Research Center

The Super Guppy’s entire nose swings open, and cargo rolls straight in on rails.

Why does the Super Guppy open at the nose instead of using a door on the side?

Some cargo planes carry heavier loads than the Super Guppy, but few have as much room inside.

Why would NASA pick the Super Guppy for a rocket part that’s huge but light?
