Enjoy this creative ‘Bookmark/Activity’ that combines an MMS bookmark with a scale model. You will also find important URLs and QR codes for quick access to additional information about the mission. It makes the perfect visual aid when exploring giving talks about of the MMS mission while highlighting important connections to science, technology, engineering and mathematics.
When printing the pdf, select a setting that will allow you to print pages 1 and 2 (front to back) on one piece of paper! When aligned properly, the entire activity can be cut out from one piece of paper (front to back).
The information on this page is identical to and in the same order as the information found on the printed MMS Bookmark/Activity. We've enhanced the content with additional information, definitions, images, links, videos and vodcasts.
The MMS mission is composed of four identical instrumented spacecraft that will use the Earth's magnetic field as a laboratory in which to study a fundamental plasma process known as reconnection.
MMS will use a two-phase orbit strategy to explore two different regions where magnetic reconnection often occurs, one on the day side and the other on the night side of Earth. (Refer to the colored boxes in the image above.)
Each of the 8 panels found on the back of the Bookmark/Activity contain mission statistics, facts and/or ideas. We've enhanced that information with additional links, activities and resources.
“The four identically instrumented MMS spacecraft fly in an adjustable pyramid-like formation that enables them to observe the 3-D structure of magnetic reconnection.”
“Punch out this 1/31 scaled model of the MMS spacecraft. Fold down and tape the sides of each panel together. At this scale the wire booms would still be ~2 meters each!”
Optional (Wire Boom) Scale Activity:
QR Codes make great enhancements to variety of educational objects and activities. Download and place these QR Codes on bulletin boards, notebooks, worksheets, scavenger hunts, etc.
A stack of 5 pennies represents a 1/164 scale model of an MMS spacecraft. At this scale the four MMS spacecraft orbiting in a pyramid-like formation would still be over 60 yards (or ~55 meters) apart! That's over half the length of a football field!
Stacking 5 U.S. Pennies together with tape created the base for this 1/164 scale model of the MMS spacecraft. Spaghetti strands (typically 26-cm in length) were used to simulate the 8 deployable booms.
Use the dimensions in the table below will help you create your own ‘US Penny Scale’ model of the MMS spacecraft.
|Spacecraft||Actual Scale||‘U.S. Penny’ Scale 1/164|
|Width||3.15 m||01.92 cm|
|Height||1.23 m||00.75 cm|
|SDP-Wire Booms (x4)||60 m||36.59 cm|
|ADP-Antenna Mast (x2)||14.75 m||08.99 cm|
|Magnetometer Booms (x2)||5 m||03.05 cm|
MMS investigates how the sun's and Earth's magnetic fields connect and disconnect, explosively transferring energy from one to the other – a process that occurs throughout the universe, known as magnetic reconnection.
