#5 Joining the OTA EQUIPMENT SECTION to the AFT SHROUD

1. Apply glue to the OTA EQUIPMENT SECTION where indicated.
2. Press the OTA EQUIPMENT SECTION to the INNER RING where indicated.

#6 Assembling the BARREL INSERT

1. Cut out the BARREL INSERT, MIRROR SUPPORT, and SECONDARY MIRROR SUPPORT.
2. Trace the circle of the MIRROR SUPPORT on the aluminum foil. and cut out the circle. Glue the foil to the MIRROR SUPPORT.
3. Glue the SECONDARY MIRROR SUPPORT onto the aluminum foil.
4. Cut the slits for the assembly tabs on the BARREL INSERT. Curl the paper to form a tube by dragging it over the edge of a table or desk.
5. Form the BARREL INSERT by rolling the paper, with the black side inward. and inserting the tabs into the slits. Hold the tube together by applying tape to the outside.
6. Fold the glue tabs of the MIRROR SUPPORT inward toward the foil side. Coat the tabs with glue. Bond the MIRROR SUPPORT to the end of the BARREL INSERT with the glue tabs to the outside.

#7 Joining the APERTURE DOOR to the BARREL INSERT

1. Cut out the APERTURE DOOR.|3|b|sans}}
2. Apply glue to the back side of the middle glue tab and to the front side of the remaining two tabs.
3. Spread the glue tabs. and attach the APERTURE DOOR to one end of the BARREL INSERT over the seam. The middle tab should be on the inside and the other tabs on the outside. Press the tabs to the tube.

#8 Inserting the SOLAR ARRAY and ANTENNA Rods

1. Use the punch to make four small holes in the side of the FORWARD SHELL and LIGHT SHIELD at the places indicated. (Look for the e.)
2. Carefully insert the two dowel rods into the holes so that each extends through to the opposite side. The ANTENNA rod is inserted through the holes closest to the AFT SHROUD. The SOLAR ARRAY rod is inserted through the holes closest to the APERTURE end of the FORWARD SHELL and LIGHT SHIELD.

#9 Assembling the SOLAR ARRAYS

1. Cut out each SOLAR ARRAY. Punch out the small circular holes in the two tabs. When the front and back sides of the arrays are together. both tabs should stick out. You will slide the tabs over the ends of the SOLAR ARRAY rod you inserted into the FORWARD SHELL and LIGHT SHIELD in the previous step.
2. Fold the two back side panels of each array along the dotted line. Coat the inside of the front array with glue, and press the back panels to it. When the glue is dry, slip the SOLAR ARRAY rod through the holes in the two tabs for each array.

#10 Assembling the ANTENNAS

1. Cut out the ANTENNAS.
2. Glue the back side of each ANTENNA assembly. Fold the front and back of each ANTENNA over the ends of the ANTENNA rod. Press the front and back together. Then, fold the reinforcing strips around the back of each ANTENNA to help hold the pieces together.

#11 Inserting the BARREL INSERT

1. Insert the BARREL INSERT into the FORWARD SHELL and LIGHT SHIELD so that the APERTURE DOOR is opposite the seam of the cylinder.

The NASA Hubble Space Telescope model is now complete. You can display it by suspending it from the ceiling by a piece of thread or monofilament fishing line or by creating a base for it.
