Earth Origami
Carl Skalak was on a solo canoe trip in the
Adirondack Mountains of upstate New York when a
surprise storm brought three days of high winds and
heavy rain that eventually turned to snow. When the
weather cleared, the river was frozen over and he was
surrounded by high drifts of heavy snow.
NOAA’s National Environmental Satellite,
Data, and Information Service (NESDIS)
operates a search and rescue system known
as COSPAS-SARSAT, in cooperation with the
U.S. Coast Guard, the U.S. Air Force, and
the National Aeronautics and Space Admin-
istration. This system can detect emergency
signals from Personal Locator Beacons
anywhere in the world. Carl Skalak’s PLB
may have saved his life.
“I knew I couldn’t get out on my own, and didn’t
know if that situation would change for the positive
anytime soon.”
Skalak activated a Personal Locator Beacon (PLB),
which sent a distress message to NOAA’s Search
and Rescue Satellite Aid Tracking System (SARSAT).
According to Lt. Daniel Karlson, SARSAT operations
support officer for NOAA, “Mr. Skalak was facing
a life-threatening situation because of his isolated
conditions and the brutally frigid weather. In a
matter of a few hours, he might have become acutely
hypothermic putting his life at risk.” The SARSAT distress
signal was relayed to the Air Force Rescue Coordination
Center at Langley Air Force Base, Va., which in turn notified
the nearest rescue unit, the U.S. Army Fort Drum Air
Ambulance Detachment near Watertown, N.Y. A few hours
after activating his PLB, Mr. Skalak was rescued.

NESDIS uses satellites for many other
purposes in addition to search and rescue,
and gathers information about Earth’s
environment that includes the location of
major ishing areas, hurricanes, tsunamis,
earthquakes, ires, and volcanoes, as well
as information about Earth’s habitats, geology,
and climate. NOAA makes this information avail-
able to many people for many different purposes.
Here’s one example of a special NESDIS product:
satellite images of Earth, assembled so that the
combined image can be folded to produce a three-
dimensional object that is almost round.

fold along the same crease in the opposite
direction. Unfold the image so it is a square
again.
5. Put your thumbs on the ends of the horizon-
tal crease formed in Step 2. Push the sides
of the square together, and latten into a
triangle. The longest side of the triangle
should be closest to you.
How to Do It
1. Cut the Origami Balloon image into a square.
2. Put the square image face-up on a lat
surface so that the NOAA logo is right-side-
up. Fold the bottom edge to the top edge,
and make a crease that passes through the
center of the square. Now unfold and refold
along the same crease so the image is fac-
ing out. This will make it easier to shape
the model in later steps. Unfold the image
so it is a square again.
4. Fold the other corner to the opposite corner,
and make another diagonal crease so that
you now have three creases that cross in
the center of the square. Unfold and re-
fold along the same crease in the opposite
direction. Unfold the image so it is a square
again.
6. Notice that there are two pieces at each of
the side corners of the triangle, one on top
of the other. Take the upper piece at one of
the side corners (a), bring it to the top of
the triangle, and make a crease (b). Re-
peat with the upper piece of the other side
corner.

9. Turn the model over, and repeat Step 8.
Want to Do More?
1. See http://www.ngdc.noaa.gov/education/ed-
ucation.html for lots of other images, maps,
and activities.
10. Notice that there are two free points at the
top of the model. If you turn the model
over, there are two more free points at the
top. Fold down the left free point at the top
of the model (a). Open up the pocket on
the left, and tuck the point into the pocket.
Repeat with the right free point (b).

7. Turn the model over, and repeat Step 6.
8. Now there are two pieces at each of the side
corners, one on top of the other. Fold the
upper piece on one side to the center and
make a vertical crease (a). Repeat with the
upper piece of the other side (b).

12. Open up the shape and ind the open end
at the bottom of the model.
13. Hold the model lightly by the edges, and
blow sharply into the hole. The Earth Ori-
gami Balloon will inlate!
