This is space time series 27 episode 13 for broadcast on the

00:00:04
29th of January 2024. Coming up on space time, NASA shuts down

00:00:11
its Mars Ingenuity Helicopter mission, a mysterious monster

00:00:15
discovered in an ancient globular cluster and could

00:00:18
diamonds be driving Neptune and Uranus magnetic fields all that

00:00:24
and more coming up on space time.

00:00:27
Welcome to space time with Stuart. Gary.

00:00:47
NASA has been forced to end its history making. Mars Ingenuity

00:00:51
Helicopter mission on the Red Planet. The decision to end the

00:00:55
mission was taken by the team at NASA's jet propulsion laboratory

00:00:58
in passed into California after images showed damage to one of

00:01:02
the rotocop it's blades.

00:01:04
The problems began when NASA suddenly lost contact with

00:01:07
Ingenuity during its 72nd flight on January the 18th.

00:01:11
The mission was designed to simply be a quick pop up

00:01:14
vertical flight in order to check out the helicopter systems

00:01:17
following an unplanned early landing during its previous

00:01:20
flight data sent by Ingenuity to the perseverance rover which

00:01:25
then relays the telemetry back to earth indicated that the

00:01:28
tissue box sized drone successfully climbed to its

00:01:31
aside maximum altitude of 12 m.

00:01:34
It then hovered there for 4.5 seconds before starting its

00:01:38
descent at a velocity of a meter per second. However, during the

00:01:42
descent, when it was still a meter off the ground, the 1.8 kg

00:01:45
helicopter suddenly lost contact with the rover. Our Ingenuity

00:01:50
had lost communications before usually when direct line of

00:01:53
sight signals to the rover were blocked by terrain.

00:01:56
Mission managers were able to re establish contact with the rover

00:01:59
the following day after instructing perseverance to

00:02:02
undertake long duration listening sessions.

00:02:05
Once contact had been re established, more information

00:02:08
about the flight was then relayed back to ground

00:02:10
controllers at JPL. Now at this stage, the course of the

00:02:14
communications dropout is still being investigated. Also,

00:02:18
mission managers still don't know why the previous mission

00:02:20
ended abruptly.

00:02:22
But when they reviewed the latest data, they found that one

00:02:24
or more of the rotor blades had sustained damage during the

00:02:27
landing and was no longer capable of flight. Right now.

00:02:31
Ingenuity remains upright on the ground and in communication with

00:02:36
mission managers, the helicopter was originally sent to Mars with

00:02:40
perseverance as a technology demonstrator.

00:02:43
It was designed to perform just five experimental test flights

00:02:46
over 30 days to see if it was even possible to fly in the

00:02:50
ultra thin Martian atmosphere.

00:02:52
Ingenuity had landed on Mars on February the 18th 2021 attached

00:02:57
to the undercarriage of the car sized perseverance rover. The

00:03:01
tiny helicopter's historic first flight off the Martian surface

00:03:04
was on April the 19th proving once and for all that powered

00:03:08
controlled flight on Mars was possible.

00:03:11
After notching up another four flights Ingenuity embarked on a

00:03:15
new mission as an operations demonstration, serving as an

00:03:19
aerial scout for the perseverance rover. Finding

00:03:22
interesting features ahead of the rover and warning of any

00:03:25
dangerous terrain best avoided.

00:03:27
Now, almost three years and 1000 Martian days later, Ingenuity

00:03:32
has performed 72 flights. That means it's flown more than 14

00:03:36
times further and 33 times longer than originally planned.

00:03:40
Logging in more than two hours of overall flight time in the

00:03:43
process.

00:03:45
Over its extended mission, Ingenuity was upgraded on

00:03:48
several occasions giving it the ability to autonomously choose

00:03:52
landing sites in treacherous terrain, deal with a dead sensor

00:03:55
and clean itself. After dust storms, it operated from 48

00:04:00
different landing sites performed three emergency

00:04:03
landings and it survived a frigid Martian winter.

00:04:07
But there were problems. Ingenuity was unable to power

00:04:10
its heaters throughout the night during the coldest parts of the

00:04:13
Martian winter, resulting in the flight computer periodically

00:04:16
freezing and resetting these power brown outs required team

00:04:20
managers to redesign Ingenuity's winter operations in order to

00:04:23
keep flying with final flood operations.

00:04:26
Now concluded mission managers will perform final tests on the

00:04:30
helicopter systems and download the remaining imagery and data

00:04:33
in Ingenuity's onboard memory.

00:04:36
Sadly, the perseverance roe is currently too far away to

00:04:39
attempt to get an image of the helicopter at its final resting

00:04:42
place. NASA Administrator Bill Nelson says the helicopter's

00:04:46
performance and resilience in the hash Martian environment

00:04:49
greatly exceeded expectations.

00:04:51
It is bittersweet that I must announce that Ingenuity, the

00:04:56
little helicopter that could and it kept saying, I think I can, I

00:05:00
think I can. Well, it is now taken its last flight on Mars as

00:05:05
it was coming for landing. At least one of its carbon fiber

00:05:11
rotor blades was damaged.

00:05:13
We're investigating the possibility that the blade

00:05:16
struck the ground. It's a special fiber with a special

00:05:20
contour that little helicopter could fly in a 1% atmosphere,

00:05:26
not 100% atmosphere like we have on earth. It cut through a 1%

00:05:33
atmosphere and was able to fly. And what Ingenuity accomplished

00:05:38
far exceeds what we thought possible.

00:05:41
Almost three years ago, the helicopter made its first flight

00:05:45
on the planet Mars and living up to its name. Ingenuity made

00:05:56
history as the first aircraft to make a powered controlled flight

00:06:00
on another planet. But then it flew farther and higher than we

00:06:05
ever thought possible.

00:06:06
And what started as a technology demonstration with plans for

00:06:10
only up to five flights has now completed a remarkable 72

00:06:15
flights on Mars and the innovation doesn't stop here. It

00:06:20
acted as a scout for the perseverance rover. It would go

00:06:25
and check out sites.

00:06:26
Ingenuity demonstrated how flight can enhance operational

00:06:31
missions and it's helping us in the search for life on Mars. And

00:06:36
like the Wright brothers, what they did back here on earth at

00:06:40
the early part of the last century, Ingenuity has paved the

00:06:45
way for future flight in our solar system and it's leading

00:06:49
the way for smarter safer human missions to Mars and beyond.

00:06:53
NASA proved once again that with relentless determination in the

00:06:59
power of America's best minds. Anything is possible. That's

00:07:04
what we try to do at NASA. Make the impossible possible. And so

00:07:11
thank you Ingenuity. That's Bill.

00:07:14
Nelson, the administrator of NASA. And this space time still

00:07:19
to come. Discovery of a Mystery Monster in the heart of an

00:07:22
ancient globular cluster. And a new study suggests that diamonds

00:07:27
could be driving the magnetic fields of the ice giants,

00:07:30
Neptune and Uranus. All that and more still to come on space

00:07:35
time.

00:07:52
Astronomers may have detected a mysterious monster in the heart

00:07:56
of 47 canI one of the most famous Clolar clusters in the

00:08:00
sky. The object reported in the Astrophysical Journal could be

00:08:04
either a rarely seen and long sought after intermediate mass

00:08:07
black hole or a pulsar. A rapidly spinning neutron star.

00:08:12
It was picked up as scientists were undertaking the most

00:08:15
sensitive and detailed radio image ever undertaken of this

00:08:18
spectacular globular cluster. Globular clusters are ancient

00:08:22
stellar spheres containing thousands to millions of tightly

00:08:26
packed stars.

00:08:27
They're thought to be either the relic nuclei of dwarf Galaxies

00:08:31
that have lost the rest of their stars during galactic mergers or

00:08:35
there could be families of stars which are all born together at

00:08:38
the same time in the same molecular gas and dust cloud

00:08:42
globular clusters tend to hover around the edges of Galaxies.

00:08:46
The milky way is thought to have at least 150 of them.

00:08:49
47 Chicana, which is also known as NGC 104 is located around

00:08:54
50 light years away in the direction of the constellation

00:08:58
Chicana. It's the second brightest globular cluster in

00:09:01
the night sky after Omega Centauri, one of the study's

00:09:05
authors, Dr Ash Beaman from the Curtin University node of the

00:09:09
International Center For Radio Astronomy Research says 47 canI

00:09:13
is one of the most massive globular clusters in the galaxy.

00:09:17
It has over a million stars and a very bright dense central

00:09:21
core. The ultra sensitive image of the cluster was created for

00:09:25
more than 450 hours of observations using the Csiro's

00:09:30
Australia telescope compact array near Narrabri in North

00:09:33
Western New South Wales Braian says 47 Chicana can be seen with

00:09:39
the unaided eye and was first cataloged by astronomers back in

00:09:42
the 17 fifties.

00:09:44
But imaging it in such great detail has now allowed

00:09:47
astronomers to discover an incredibly faint radio signal at

00:09:51
the center of the cluster that had never been detected.

00:09:53
Previously, the signals suggest that 47 to Canny contains either

00:09:59
an intermediate mass black hole or a pulsar intermediate mass

00:10:03
black holes are extremely rare they have masses somewhere

00:10:06
between that of a supermassive black hole of the type fat at

00:10:09
the centers of Galaxies and the stellar mass black hole which

00:10:13
are created by collapsed stars.

00:10:15
We see lots of both stellar mass black holes and supermassive

00:10:19
black holes. But finding intermediate sized black holes,

00:10:22
something that fits between the two is extremely rare. And while

00:10:27
intermediate black holes are thought to exist inside globular

00:10:30
clusters, there's never been a clear detection of one.

00:10:33
Now, if the signal turns out to be an intermediate sized black

00:10:36
hole, it would be a highly significant Discovery and the

00:10:39
first ever radio detection of one inside a cluster. Now, the

00:10:43
second possible source for the signal is a pulsar, a rotating

00:10:46
neutron star that emits radio waves, neutron stars will

00:10:49
collapse still a cause of stars far more massive than the sun.

00:10:53
They spin incredibly fast, producing a beam of energy that

00:10:57
shines out across the universe like a lighthouse. Beacon Burian

00:11:01
says a pulsar this close to a cluster center is also

00:11:04
scientifically interesting because it could be used to

00:11:07
search for a central black hole that's yet to be detected.

00:11:11
Is one of the brightest glo clusters in the night sky and it

00:11:15
's partially because it's very large compared to other glove

00:11:18
clusters and partially because it's relatively close when we

00:11:21
consider galactic distance.

00:11:22
Now, what we have done is we have used Csiro's telescope

00:11:27
compact array to looked at this cluster and pushed the

00:11:31
sensitivity of the observatory to its limits. We looked at it

00:11:35
for 450 hours of observation. We looked at it and what has

00:11:39
happened, this allowed us to make the deepest radio image

00:11:43
ever made of a glove cluster.

00:11:45
Now, the reason this is exciting is because glove clusters are

00:11:50
among the oldest parts of our galaxy, they were formed when

00:11:53
the galaxy was very young. So these are we are talking about

00:11:56
10 billion years old roughly in age.

00:11:59
So what we are looking at is this collection dense collection

00:12:03
of stars that some stars that were very massive has already

00:12:07
gone, have already gone through the stages of stellar life and

00:12:11
turned into stellar remnants, things like black holes or

00:12:15
neutral stars which are dense remnants of stars.

00:12:18
And now those remnants are still moving around in the globular

00:12:23
cluster and occasionally interact with other stars that

00:12:26
are around. And these interactions create energetic

00:12:29
signatures, either X ray emission or radio emission that

00:12:33
we can observe.

00:12:34
So when we observe with this amount of sensitivity with this

00:12:38
much effort and push things to the to make the deepest image,

00:12:42
we start to capture some of the things that have been hidden and

00:12:46
we have never captured before. So now we see the deepest image,

00:12:49
we are starting to see neutral stars and black holes that have

00:12:52
never been seen before in this cluster.

00:12:54
At the center of the cluster, we notice a very faint source at

00:12:59
the center of the globular cluster. Now this was exciting

00:13:01
for multiple reasons because typically at the center of these

00:13:05
globular clusters is where the density is the highest.

00:13:08
This is where you expect some more exotic elements of the

00:13:11
cluster to be. For example, one of the things that have been

00:13:15
speculated for a long time to be present at the center of the

00:13:19
globe cluster is an intermediate mass black hole.

00:13:23
So what that is when we look at the black holes in the universe,

00:13:27
we see two main groups, we see stellar mass black holes. These

00:13:31
are black holes that are formed when stars die, heavy stars die

00:13:35
and they turn into stellar mass black holes a few times more

00:13:39
massive than our sun.

00:13:41
At the other end, we have supermassive black holes. These

00:13:43
are black holes at the center of the galaxy. They are millions of

00:13:47
times heavier than the sun. So these are the two groups that we

00:13:51
have observed. We have measured their masses, we know of their

00:13:54
existence.

00:13:55
However, this is kind of like the situation is kind of like

00:13:59
going into a village and you see toddlers and you see adults, but

00:14:04
you don't see any teenagers, but you infer that there's got to be

00:14:08
some teenagers, you just haven't seen them, maybe they are at the

00:14:11
playground that you haven't seen. This is the kind of

00:14:13
situation with intermediate mass black holes.

00:14:15
We have seen the stellar mass black holes we have seen the

00:14:18
supermassive black holes. There are a few intermediate mass

00:14:21
black hole candidates that have been identified in the cosmos.

00:14:24
But one of the places is that people have speculated these

00:14:28
intermediate mass black holes should be is center of glo

00:14:31
clusters.

00:14:32
And that is one of the exciting interpretations of that same

00:14:36
signal that we have seen in the center of our glove cluster. So

00:14:40
that's very exciting. If true, it would be, it would, it would

00:14:44
allow us to understand more about the black holes and how

00:14:48
they grow, how they evolve. The other interpretation of this

00:14:52
signal is that it could be a pulsar.

00:14:54
Pulsars are so neutron stars are dense remnants of stars that

00:15:00
explode. These are very dense, we're talking densities that are

00:15:04
tens of thousands of times. So if you have, if you have a

00:15:07
spoonful of matter from a neutron star, that matter, that

00:15:10
will be heavier 10 times roughly more than Sydney Opera

00:15:16
house. So that's the density we are talking about here.

00:15:19
So neutron stars, some of them rotate very rapidly. This rapid

00:15:24
rotation allows a period to make them appear pulsating from our

00:15:29
point of view. So the other interpretation is that this

00:15:32
signal we have seen at the center of the globular cluster

00:15:34
could be a pulsar that is also exciting because pulsars are

00:15:38
amongst some of the most precise clocks in the universe.

00:15:41
So by tracking it is really a pulsar which follow up studies

00:15:45
may confirm that allows us to understand the dynamics at the

00:15:49
center of the cluster with some of the most precise clots in the

00:15:53
universe. So either of the two interpretations are very

00:15:56
exciting and allow us to understand how glove clusters

00:16:00
have evolved stars in the galaxy have evolved to get here.

00:16:03
The other exciting factor about this Discovery and study was the

00:16:07
fact that we have pushed the sensitivity of our current

00:16:11
generation of observatories to their limit. And this is

00:16:14
exciting as we prepare for the next generation of observatories

00:16:18
such as square kilometer array, which is currently being built

00:16:21
in Western Australia.

00:16:22
As we learn about the techniques that we are developing, as we

00:16:26
learn about the challenges that we may face as we accumulate

00:16:29
this much data and we try to make sense of it. These kinds of

00:16:32
studies allow us to be more efficient and harness all of the

00:16:36
science that we can capture from the next generation of

00:16:39
observator.

00:16:39
When you look at the density of the material around the center

00:16:44
of the globular cluster, are you able to differentiate stars or

00:16:48
other objects orbiting around the central point? I guess where

00:16:52
I'm getting at there is any idea of the mass of the.

00:16:55
Object we cannot get the mass dynamically. What I mean

00:16:58
dynamically is, for example, sometimes when we look at binary

00:17:03
star systems, we can easily apply Newtonian mechanics at the

00:17:07
orbit and say OK, these have to be the masses. However, there

00:17:11
are other indirect methods to infer the mass.

00:17:15
For example, we can look at the bright of it. And we say, well,

00:17:19
if it is this class of objects based on how much energy it's

00:17:23
releasing, this is the mass it can have. So under that

00:17:28
interpretation, under these methods, if this is a black

00:17:32
hole, we expect its mass to be around a few 100 times more

00:17:36
massive than the.

00:17:37
See, that's important because this really does put us in those

00:17:41
teenage years that we've been looking forward to.

00:17:43
So it's the range that we are typically we consider

00:17:46
intermediate. It's not a clear cut definition, but roughly we

00:17:52
would say a few 100. So around 200 is where stellar evolution

00:17:58
models cannot really predict black holes of that mass around

00:18:03
102 100 roughly all the way to around 100. That that's the

00:18:08
range that really is hard to find black holes in that range.

00:18:12
Now, at the upper end, like a few 100, a few 10 thousands,

00:18:17
there are now a few good candidates that have been found

00:18:20
at the center of what we call dwarf Galaxies. These are

00:18:23
Galaxies that are not really the size of milky way or Andromeda,

00:18:27
they are very tiny, but they are in the same system of Galaxies,

00:18:31
for example.

00:18:32
And some of them seem to host black holes at the center that

00:18:36
may be 10 times more massive than the sun or 100 times

00:18:40
more massive than the sun. So in that context, when we look at it

00:18:44
finding a black hole that only a few 100 solar mass at the center

00:18:49
of the cluster. It is quite surprising and interesting

00:18:52
because we're saying that we are finding this awkward zone that

00:18:56
is just more mass than stellar mass black holes.

00:19:00
But at the very low end of the intermediate mass black hole

00:19:03
spectrum. So it is exciting, it tells us it also reveals because

00:19:07
of its low mass, if it's a common pattern among other glove

00:19:11
clusters, it is telling us that because of this low mass, that's

00:19:14
why we haven't in previous efforts because they are so

00:19:18
light that you need so much observation to actually detect.

00:19:22
And of course, the other problem is is has the universe been

00:19:25
around long enough for a stellar mass black hole to grow into a

00:19:29
supermassive black hole assuming they the same way precisely.

00:19:33
Yes, that is one of the problems that the growth theory as to

00:19:40
which is stellar mass, black holes merge and become larger

00:19:44
and larger. And black holes is that actually a viable theory

00:19:49
given the age of the universe.

00:19:52
When you look at this globular cluster, and you look at the

00:19:55
stars within it, are they made out of the same material as the

00:19:59
other stars within that part of the milky way galaxy. In other

00:20:04
words, do they all have the same sort of metallic or are we

00:20:07
seeing something which may once have started out as the core of

00:20:11
a different galaxy?

00:20:12
Oh, that's a fantastic question. So for 47 Takane, we actually

00:20:19
what we see is metallic is comparatively with like for

00:20:23
example, other parts of the galaxy around it, it is a bit

00:20:26
more metal for because and that is expected because we expect

00:20:30
stars in the 47th economy to be a lot earlier. So you expect

00:20:36
them to be older. So that's what we are seeing.

00:20:39
However, what you said about the core of other Galaxies that app

00:20:44
that applies to a a couple of glove clusters in our galaxy

00:20:48
that their distribution of elements their and sometimes

00:20:53
even their shape is a bit unusual compared to other glove

00:20:57
clusters in our galaxy.

00:20:59
And there is this ongoing discussion and study if some of

00:21:03
them may have been small galaxy that interacted with our galaxy

00:21:08
and got stripped of some of their stars and became what

00:21:11
looks like a globe cluster, but they weren't a glob cluster from

00:21:15
the beginning. But for 47 we're pretty sure they are the stars

00:21:20
in that cluster formed as part of the milky way.

00:21:23
Where is your research going to take you next?

00:21:26
So there are two important two exciting bits that we are really

00:21:32
keen to follow. First is that the amount of data we have

00:21:35
collected on 47 Kan with this project, there is still a lot of

00:21:41
exciting stuff to explore and analyze. We made the first image

00:21:45
which is the deepest image. And the most exciting thing was the

00:21:49
source in the center.

00:21:50
There are a lot of other signals in the cluster are likely to be

00:21:54
Neutra stars or other types of less exotic objects that we are

00:21:58
going to explore and understand. And then after that, there are

00:22:01
also my focus is now on understanding the population of

00:22:06
black holes in our galaxy. I'm trying to understand how many

00:22:09
stellar mass black holes are in our galaxy.

00:22:11
What fraction of them are we really able to observe? Because

00:22:15
black holes are notoriously hard to observe because they don't

00:22:19
have any light and they are only observed when they interact with

00:22:22
other stars or the like of other stars. So trying to connect the

00:22:27
theoretical expectation of population of black holes to

00:22:29
what is actually observed is one of the my goals in the.

00:22:34
Next few years. That's Dr ash beam from the Curtin University

00:22:38
know of the International Center For Radio Astronomy Research and

00:22:42
this space time still to come, could diamonds be driving

00:22:47
Neptune and Uranus magnetic fields? And later in the science

00:22:51
report, NASA's new experimental supersonic aircraft specifically

00:22:55
designed not to generate a sonic boom, all that and more still to

00:23:00
come on space time.

00:23:18
A new study suggests that diamond rain in the dense

00:23:21
atmospheres of the ice giants, Uranus and Neptune could be

00:23:24
driving these distant worlds magnetic fields. The findings

00:23:29
reported in the Journal Nature Astronomy are based on new

00:23:32
resolutions to long standing issues about the temperature and

00:23:35
pressure conditions under which diamonds form from short lived

00:23:38
hydrocarbons such as those expected to be found inside

00:23:42
these ice giants.

00:23:44
The authors use sophisticated computer modeling to describe

00:23:47
the internal conditions deep inside the atmospheres of both

00:23:51
Uranus and Neptune and then monitor how small samples of

00:23:54
planetary building blocks behave and rearrange under these

00:23:57
extreme conditions.

00:23:59
Previous modeling had already provided scientists with a

00:24:01
fairly rough idea of the processes by which diamonds form

00:24:05
from short lived hydrocarbon molecules inside ice giant

00:24:09
interiors.

00:24:10
But different lab techniques have been yielding varying

00:24:13
results making it challenging to pin down the exact depth at

00:24:17
which this process occurs. The main debate centered on

00:24:20
experiments that compress hydrocarbons to bring them to

00:24:23
pressure extremes and the experiments that create these

00:24:26
conditions are hitting samples with high speed projectiles

00:24:30
mimicking a meteor impact.

00:24:32
Instead, the authors of this study used an X ray laser

00:24:35
capable of generating ultra short flashes 27 times per

00:24:39
second. This would then hit a compressed sample of polystyrene

00:24:43
with ultra short X ray flashes producing a sort of goldilocks

00:24:47
method to resolve the tension between the two early

00:24:49
approaches.

00:24:51
They found that diamond formation was observed under

00:24:54
pressures ranging from 19 to 27 gap pascals and above 2500

00:24:59
Kelvin. Now what all that means is that diamond rains form at

00:25:04
shallower depth than previously thought. And because it's denser

00:25:09
than the surrounding material, it sinks deeper, providing an

00:25:12
additional heat source which could then drive convection in

00:25:15
the ice layer.

00:25:16
And it's that which could be contributing to these planets

00:25:19
complex magnetic fields. This is space time and time now to take

00:25:40
a brief look at some of the other stories making news in

00:25:43
science this week with the science report, a new study

00:25:47
warns that as little as a single degree in average global

00:25:50
temperature increase could shorten your life by as much as

00:25:53
half a year.

00:25:54
A report in the journal PLOS one shows that just one °C of

00:25:59
warming may cost an average of six months off the average human

00:26:03
lifespan with women and people in developing nations facing the

00:26:06
most significant consequences.

00:26:09
The findings are based on studies of data from 191

00:26:12
different countries. The study looked at how direct factors

00:26:16
such as storms and indicative factors such as mental illness

00:26:20
all contribute to an overall lowering effect on global human

00:26:24
life expectancies.

00:26:27
NASA has unveiled a new experimental supersonic aircraft

00:26:30
specifically designed not to generate a sonic boom. The

00:26:34
technological advances made to the aircraft known as the X 59

00:26:38
reduce the usual air splitting crack of the sonic boom to a

00:26:41
more quiet thump as the aircraft breaks the sound barrier.

00:26:46
The key is a new ultra thin tapered nose design which breaks

00:26:50
up the shockwaves traditionally created when an aircraft

00:26:52
traverses the sound barrier. But the configuration means the

00:26:56
cockpit is located almost halfway down the length of the

00:26:58
aircraft and it does not have a forward facing window.

00:27:02
Instead, the X 59 team developed an external vision system using

00:27:06
a series of high resolution cameras which are then feeding a

00:27:09
set of four K monitors in the cockpit. The aircraft also uses

00:27:13
a top of fuselage mounted engine resulting in a smoother belly to

00:27:17
help keep shockwaves from merging behind the aircraft and

00:27:20
causing a sonic boom.

00:27:21
The aircraft was unveiled at Lockheed's secret Skunkworks

00:27:25
facility in the Mojave Desert. NASA project integration

00:27:28
manager, Peter Cohen says the X 59 will undertake its maiden

00:27:32
flight later this year before attempting its first quiet

00:27:35
supersonic transit.

00:27:37
The test flights will initially occur at the skunk works before

00:27:40
transferring down the road to NASA's Armstrong Flight Research

00:27:43
Center at the Edwards Air Force Base. NASA hopes the new

00:27:47
supersonic transport could revolutionize air travel. Paving

00:27:50
the way for a new generation of commercial aircraft.

00:27:53
It can travel faster than sound. Of course, the Concorde did all

00:27:57
this during the 19 sixties and seventies but it left a sonic

00:28:00
boom that resulted in governments banning it from

00:28:03
achieving supersonic speeds over land. It therefore became

00:28:07
restricted the supersonic flight only on transatlantic journeys.

00:28:13
A new study has confirmed that most dogs love watching TV and

00:28:18
the findings by researchers from the University Of Wisconsin

00:28:20
Madison also show that man's best friends do have their

00:28:24
favorite shows. The two year study reported in the applied

00:28:28
animal behavior science journal was designed to learn what video

00:28:32
content engaged poos.

00:28:33
The most 1600 dog owners from the United States, Canada,

00:28:37
Europe, the UK, Australia and New Zealand were asked to fill

00:28:40
out a questionnaire looking at how their dog behaved when the

00:28:43
TV was on. And it seems our furry friends love cartoons with

00:28:48
animals in them, best of all and no surprises for guessing.

00:28:52
They especially love those with dogs in them. They also like

00:28:55
other nature documentaries, you know, anything with animals in

00:28:58
them again, especially those with dogs in them. But

00:29:01
interestingly, they find shows with humans fairly boring.

00:29:06
A new study has found that 42 per cent of Americans claim

00:29:09
they've felt a paranormal presence in their home. 37 per

00:29:13
cent claim they've heard unexplained sounds such as

00:29:16
footsteps or voices and 19 per cent say they've actually seen

00:29:20
apparitions or ghostly figures.

00:29:23
The study also shows that 49 per cent of strange experiences,

00:29:26
paranormal experiences that is happen in the bedroom 26 per

00:29:31
cent in the living room, 23 per cent of the kitchen, 21 per cent

00:29:34
of the hallway were on the stairs but only 12 per cent in

00:29:37
the basement. Some nine per cent of those surveyed prayed right

00:29:41
after the experience happened.

00:29:43
The research also found that one in 10 of the Americans surveyed

00:29:46
have used a Ouija board in their home and of those 42 per cent

00:29:50
said they'd never do it again. Amazingly, seven out of the 1017

00:29:55
people surveyed didn't stick around to figure out what had

00:29:58
happened and actually moved away from their home.

00:30:01
After the experience, over 40 per cent said their community

00:30:05
has a long history of local ghost stories and more than half

00:30:08
believe the stories are real. But Tim Mendham from Australian

00:30:12
Skeptics says those funding this study are advising people to try

00:30:15
something else first before resorting to an exorcist.

00:30:19
If anyone in an old home knows that the thing creaks and it

00:30:22
settles and all sorts of noises are being made. This was a study

00:30:25
done of about 1000 people in America asking them a range of

00:30:29
questions. Do you notice sounds and things? Do you notice any

00:30:32
strange occurrences? Where do you notice them? What reactions

00:30:35
do people have to the?

00:30:36
And is your house haunted? So, what they found out was that

00:30:38
about 42 per cent of people felt there was a paranormal presence

00:30:42
in their home and 16 per cent thought the house was haunted.

00:30:45
37 per cent had an unexplained sounds and things and 19 per

00:30:50
cent had seen apparitions quite an extensive survey.

00:30:53
Actually, one of the issues they point out is that a lot of the

00:30:56
phenomena might be caused by the house, not by being haunted, but

00:30:59
if it's an old house, you've got things coming adrift, you've got

00:31:02
the fiber board here of a house or something is creaking a bit.

00:31:05
It's coming loose, letting wind in windows, rattling all sorts

00:31:08
of things.

00:31:09
One of the points they made was that some people reported

00:31:11
stationary objects moving such as doors and windows, which I

00:31:14
didn't thought it was stationary objects that they can move. That

00:31:17
's part of the principle for those things. But yeah, the

00:31:19
interesting thing about the survey is it's actually done by

00:31:22
a home repair company.

00:31:24
Now, the survey might be legit. But the, the solutions they

00:31:29
offer is, I think it's a very inventive one. Actually, this

00:31:32
particular survey, I think it's lovely. They actually

00:31:35
commissioned a survey so they might have had this in mind all

00:31:38
along.

00:31:38
But the eerie encounters that people have, the interesting

00:31:41
thing is certain rooms are eerier than others and obviously

00:31:44
the room, which is the eeriest and has the most paranormal

00:31:47
events is the bedroom. Now, what do you do in the bedroom? Well,

00:31:50
there's, there's always a it, yeah, you sleep and it's dark

00:31:56
and hopefully it's dark, you turn the lights off and go to

00:31:58
sleep.

00:31:59
So naturally that is a room that lends itself to spooky feelings,

00:32:02
especially if you're only half awake and you're sort of in a

00:32:04
dream state, etcetera, if you're more likely to see a ghost in a

00:32:08
bedroom than you would say in a kitchen where it's pretty

00:32:11
bright, half of the knives and things around there.

00:32:12
You're fairly safe from ghosts. But all sorts of these things is

00:32:15
quite fascinating little survey. But saying that in America there

00:32:18
's a lot more older houses and perhaps they are where I live,

00:32:21
which is a newish sort of suburb where the houses might range

00:32:24
from average age to be 50 years old.

00:32:25
And they're suggesting that this is a factor in the sort of

00:32:28
haunting and paranormal things that people report and of

00:32:30
course, summer old houses are pretty spooky just in their own.

00:32:33
Right. If you're seeing noises, if you see hearing sort of

00:32:36
seeing visions and things, go talk to your home repair

00:32:38
company, don't exercise, renovate the best solution.

00:32:41
