Jupiter Infrared Aurora Mapper

00:06.100 --> 00:08.150
is an image spectrometer.

00:08.150 --> 00:13.080
At the beginning it was meant for supporting aurora observations,

00:13.080 --> 00:15.190
to make images of aurora,

00:15.190 --> 00:20.080
and at the same time to look at the different

00:20.080 --> 00:23.030
different view of the aurora.

00:23.030 --> 00:25.170
JIRAM is made of two pieces.

00:25.170 --> 00:30.090
One part of JIRAM is called the optical head.

00:30.090 --> 00:34.100
It's where is the sensitive part of the instrument

00:34.100 --> 03:140.000
that can focus the images, like a camera.

03:140.000 --> 00:39.110
And there is another box,

00:39.110 --> 00:41.060
which is the main electronic.

00:41.060 --> 00:46.070
And we can take images into different wavelengths.

00:46.070 --> 00:50.090
One is devoted to the aurora observations

00:50.090 --> 00:54.200
and the other part of the director -- the imager --

00:54.200 --> 00:58.170
is sensitive to the thermal emission of the planet.

00:58.170 --> 01:02.120
So at the same time we can take these two pictures

01:02.120 --> 01:06.020
that are superimposed one above the other one,

01:06.020 --> 01:08.200
for observing the aurora if it's present.

01:08.200 --> 01:13.000
The reason why we are not with all the other instruments

01:13.000 --> 01:16.140
but we are on a side in the half-deck of the spacecraft

01:16.140 --> 01:19.170
is because we entered the mission later

01:19.170 --> 01:21.100
so there was no more room (laughs)

01:21.100 --> 01:26.060
in the big place, in the place where all the other instruments are.

01:26.060 --> 01:31.130
So we had to run quite fast to keep the pace with the mission.
