David Sibeck: The goals of the mission are to determine where the charged particles
in the Earths radiation belts come from? How they get energized?
And how they're lost into space? Each of the two spacecraft
carries five instrument suites, and a total of eight instruments.
The two spacecraft are identical. One of the instrument suites on
the spacecraft is the ECT suite. And this instrument
suite consists of a set of instruments. The HOPE instrument measures the
coldest plasma in the Earth's radiation environment. MagEIS, measures
intermediate energy; ions and electrons. Next instrument up
is REPT and it measures still higher particles. The RBSPICE instrument
measures ring current particles and their composition. The wind
current is a region of charged particles around the Earth that greatly affects
the Earth's magnetic field. The RPS instrument
measures the radioactive particles in the inner radiation belt.
The EFW instrument measures the electric field.
And it spectacularly consists of very long wires that extend
40 to 50 meters out from the spacecraft with little
balls on the end that measure the sensitive electric field in space.
The EMFISIS instrument suite comprises two instruments.
A magnetometer out on a boom, that measures the ambient magnetic
field out in space and a search coil magnetometer that measures
wave activity in the magnetic field. I'm excited about this mission
because it's going to provide answers to questions that we've been asking a long time;
about where the particles come from in the Earths radiation belts? What charges
them up? And what causes them to move around? I've been wondering about this a long
time, and I'm ready to learn the answer.
