I hint about the only person around it doesn't have TV coverage of the things
that man got the black up now you're gonna be getting a TV picture now
they'll yes we are getting a TV picture
one all
yeah
hello and welcome to space in just a few days time
esa's rosetta mission is going to come to a close and it's going to do so in
the most extraordinary fashion because the spacecraft is going to slowly and
deliberately crash-land into the comment that it's been orbiting for the past two
years
we're with the team as they prepare for this dramatic finale
this has been a mission full of surprises from the nerve
yeah
the first was one Rosetta kept everyone waiting for it to wake up from a long
hibernation
then in November 2014 Rosetta's tiny profi landed on the comet it banks twice
and then disappeared from gear
what followed two years of sciences Rosetta surveyed the comment on its
closest approach to the Sun
yeah
then another surprise a few days ago when feel a was finally spotted in a
shady corner of the comment
so what's next we're going to land on the comet once more this time with the
mothership this system is not designed to land will not survive the lending for
no doubt
location retargeting is a real real scientific mind the dramatic finale will
come on friday the thirteenth of sep tember on that day Rosetta will put
itself on a deliberate collision course with the comments from harm with a local
net can take a model of the comment on the head of the dark there's this area
called mart which is a pretty interesting area because it's a very
active region in particular on this side there are two areas what we call pit
holes which produce gas and stuff would you guys the deepest here so the idea is
to come with the setter lands near Hawley money order to see digital thanks
to its careful custodians Rosetta has resisted 12 years in space
however it will not be able to resist this
yeah
let the structure of the satellite is very lightweight and very French Eyal
presenter in particular was absolutely not made to be able to withstand gravity
because it's a satellite in orbit around a comment a small weak party don't at
the moment of impact Rosetta will be crushed the solar panels in the antenna
will be flattened onto the surface of the comet was Davis don't resent it will
remain on the comment forever because there's no way to get it off the surface
of the comet document the mission is over because as it follows the comment
away from the Sun the spacecraft has less and less power from its solar
panels for its science masters this ending presents a unique opportunity to
take data and photos right until the act
the scenario we now have this this ballistic plunge from about 20
kilometers above the comment right down to the surface is fantastic it gives us
its unique profile of what the the comedy atmosphere the common looks like
right down to the surface and that's probing something we've never proud
before
Rosetta will send back high-resolution photos of some of the most interesting
parts of the comet offering a peek inside this ancient lump of dust and ice
left over from nearly solar system we have these regions all over the comment
actually on the back of the comment but on the head as well that their pic pit
regions by are these large cavities tens of meters hundred meters across and they
have a debris inside them rethink the fundamental in terms of the activity
that's that we see from the comment but also the sidewalls reveal some of the
internal structure and they reveal structure that we think it's absolutely
important in how that comment was made up to the small scales tens of meters
well meters to tens of meters we seeing stuff that and we want to get really
high resolution images of that so that will be a final thing looking into the
sidewalls one of those pits just before we hit for all that to happen Rosetta
has defined the last few days as it flies close to the comet and complete
the final descent
when flying very close to the surface of the comment the biggest risk is to have
problems in the navigation so in predicting where was it will be around
the comet what we're doing now technically is much much more demanding
than they will ended with feeling in the final moments there'll be no time to
make adjustments the team will just take the data and cross their fingers
if we're lucky we keep the signal until the very end we don't know with which
part of this bass cover will touch down so it could be that maybe a solar panel
touches first and then the attitude of the spacecraft was disturbed may lose
the signal so the last few minutes are going to be yeah it difficult to predict
latest when it's on the surface we will lose the signal the spacecraft will be
programmed for that because we don't want to leave an active spacecraft on
the comment that could pollute the the radiofrequency environment so it will
switch off and that would be the end of the mission
yeah
away from Rosetta now and to an update on the mission that we've been following
all year in this program and that's exomars right now the spacecraft is
really getting very close to the red planet and tension is mounting in this
episode of Destination mask
yeah
both are well my name is Michelle didn't you and I'm your flight director XO mask
yeah
move or fear little still do that Facebook we've completed most of the
cruise phase we left Earth just over six months ago and in a few weeks
we're going to arrive at Mars the correct rule we can't delay the moment
we arrive at Mars by a day or even a minute
so everything relies on us and the countdown is underway and there's no way
we can stop it live through the chances of success of the TG o orbiter are very
high and the chances of success of the lander scaparelli hide to that of course
it's more difficult to land on Mars than to put yourself into orbit around into
that . feel masculine Smith
Mark's Mars is the culmination of a dream it's this huge distances massive
spaces the idea that one day humans will go and visit this planet or even stay
there and of course there's the idea that there might have been all that
could still be life on Mars growing religious dogmas that's all for now but
of course you'll be able to follow the dramatic end the rosetta mission as it
happens live here on your news and your news.com
I hinder about the only person around it doesn't have TV coverage to the favor
and hit man you got the black up now you're gonna be done in the TV picture
is still yet we are getting a TV picture
chillin out one all
bad way
