UNIT 6, EXTRACT 2 TUTOR OK, come on in. Hi Ben, hello Mark,
Sally. Let's get going shall we, because
we've got a lot of ground to cover this
afternoon. It's Ben's turn to give his
tutorial paper today but, remember,
we do encourage questions from the
rest of you, so do try to join in and ask
questions.
BEN OK.
TUTOR Now, I believe Ben's going to talk to us
today about the exploration of the
Red Planet,
BEN That's right. I'm going to be looking at
the recent landing by the Americans
of a spacecraft on the planet Mars
and in particular focusing on the
small rover robot.
MARK Is that the little robot
that functions as a geologist? BEN Yes, that's right. It's called a rover -
like a land rover, I suppose! - and it
can detect the geological composition
of the ground it's standing on so, yes,
it's a sort of geologist. It's actually
quite amazing.
TUTOR 1 heard it described as being
like а microwave oven on wheels. BEN Yeah, well from an appearance point
of view, that's a fair description. I've
photocopied a picture of it for you, so
that you can keep this for reference
and make some notes and I'll just
hand that out now.
VOICES Thanks.
MARK Wow, you'd actually expect it to look
more space age than this, wouldn't
you? Like more sophisticated.
BEN OK, well as you can see it's quite
small. It actually only weighs 16,5 kg.
TUTOR Right, and what kind of speed is it
capable of, Ben?
BEN Um, well I suppose that depends on
the terrain, but I understand that it
has a top speed of 2.4km an hour
which isn't very fast, really.
TUTOR And can you tell us how it works,
explain some of these things we can
see here?
Recording Script
BEN Well first of all
on the top it's fitted with solar panels. It runs on solar
energy, of course.
SALLY Does that mean it can't work at night?
BEN Yes, indeed it does. I guess it sleeps at
night! So you have the solar panels on
the top, and
underneath this is the
