CHS Magnetic SubSEM 2004

Welcome to the CHS Space Program 2004 SubSEM experiment homepage.

Space and Spacecraft Induced Magnetic Fields

This experiment will fly into space aboard a NASA sub-orbital rocket in early June 2004 as one of four high schools selected in the country. It was designed by a team of high school students with guidance from teachers and gracious mentors. It aims to measure subtle magnetic changes using good quality sensors and well thought out signal processing. The end result will be a data analysis that will serve as a calibration for future rocket-based magnetometer investigations as well as provide a practice data set for a potential mission to Mars being proposed by a consortia of universities.

Data Analysis completed using Kaleidagraph 3.6. 960,000 magnetic field readings were recorded and then treated and plotted using the Kaleidagraph software.

The Experiment has been built! (5/07/04) See the latest pictures. We would not have made without help from Keith Warren and the staff at Jordan High School Metal Shop.

The primary amp/conditioning circuit is shown HERE in rough form. Updated diagram will be up Wednesday.

Click HERE for the Wiring Diagram (it is small print, so download it and open it seperately so you can zoom in for details). The wiring diagram has each part labeled.

The orginal experiment proposal has been expanded to include multiple magnetometers for precise spacecraft induced field measurements, and advanced signal processing techniques will be employed (document on new procedures to be posted in April 2004).

Here is a list of links to each part shown in the wiring diagram/experimental layout.

To mimimize space, several parts have been changed to surface mount. New spec sheets will be posted Wed.

Eighteen LM385Z IC Voltage Reference Diode to make sure output does not exceed 5V
