Constructing MAG, SEPICA, and SIS
MAG (Magnetic Field Monitor):
- Score along all folding lines. To score paper: use a black
ball-point pen, preferably with a ruler, to make an indentation in the paper.
This makes folding the pieces much easier, and results in a much nicer appearance.
- Cut the MAG instruments out along the outer lines. These
instruments are assembled as follows:
- Fold the instrument on each black line toward the unprinted
- Curl the bottom up towards the top, and apply glue to
the lighter grey tab.
- Glue the tab to the bottom end, as shown below, and
allow this to dry before proceeding.
- Fold the tabs on the sides down, as shown below.
- Glue the side piece down onto the tabs, as shown below.
- You may now wish to send an emissary to Group One. This
person can work with the person on their team who has assembled the MAG
booms, as the instrument must be glued to the booms as shown below.
MAG -- Magnetic Field Monitor -- collects data on the
sun's magnetic field, measuring the strength and direction of the interplanetary
magnetic field 30 times per second, and calculates patterns of variations.
MAG was developed by the Bartol Research Institute in Newark, DE, and by the
GSFC, and is a flight spare from the WIND mission. For more information on

SIS (Solar Isotope Spectrometer)
- SIS is a box like MAG, but with an extra face. As such,
it's pretty easy to put together.
- Score along all the folding lines. This does not include
the line between the wedge-shape and the printed faces at diagonal angles
-- they are both part of the same face.
- Fold the model up as shown in the first picture below,
so the bottom and top come together at the tab.
- Glue this tab into place, and allow it to dry before proceeding.
- Apply glue to the tabs on the sides (one side at a time),
and fold the side pieces up. Glue the tabs into place so that the model
takes the shape shown in the second picture below.
- The completed SIS model should look like the third picture
SIS was built to measure the elemental and isotopic composition
of the solar wind, in the range of elements between helium and zinc. It was
developed by researchers at Caltech, GSFC, and JPL. For more information on
SIS, please visit
SEPICA (Solar Energetic Particle Ionic Charge Analyzer)
- SEPICA is constructed in much the same way as SIS; it's
just a little more complicated.
- First score SEPICA along all the folding lines. This does
not include the lines in between the panels sticking out from the middle
face, or those on the face with the grid printed on it -- they are purely
cosmetic. Do score along all the other horizontal and vertical lines, though.
- For this version of SEPICA, I forgot to put tabs on one
key spot, as shown here at right: There should be a tab for that odd shape
to attach to the gridded side, so before you cut this shape out, draw your
own tab here.
- To assemble SEPICA:
- Fold all faces up towards the unprinted side
- Fold the gridded face back so that your hand-made tabs
attach to the middle face, and the smaller tabs can be attached to the
shorter side, as shown below.
- Next fold the bottom side upwards, gluing those tabs
in place (on the inside of the model) as you come to the faces they will
attach to, as in the picture.
- Your completed SEPICA should look like the last picture
in the series below.
SEPICA was built to measure the ionic charge state, elemental
composition, and energy spectra of energetic solar ions. It was developed
by researchers at the University of New Hampshire and the Max Planck Institute
for Extraterrestrial Physics in Germany. For more information on SEPICA, please
+Z LGAs (Low Gain Antennas)
- The LGAs are quite simple to assemble: just roll the part,
with the long edges parallel to each other, on a round pencil or pen, then
glue the tabe to the inside of the piece.
- The LGAs will eventually be attached to the +Z (top) panel.
Their purpose is to send and receive information to and from earth.
