 POLAR project in Oulu

Introduction
NASA's POLAR project, launched 24 February 1996, targets the Earth's polar regions. The
satellite is still operating, although it is past its nominal lifetime (it may last up to
2002 or 2003, but the orbit will deteriorate towards lower latitudes). Oulu is involved in
building the boom mechanisms for the electric field instrument, EFI, in collaboration with the Space Sciences Laboratory of the University of
Berkeley. We are also very interested in various ground-based activities in connection
with the Polar spacecraft.
The POLAR orbit is 1.81 x 8.9 Re with 90 degree inclination (see the figure).
