making life multi-planetary was the foundational principle of SpaceX he claims that if Humanity
were to colonize other planets like Mars civilization on Earth might be preserved
in the event of a catastrophic event like a major asteroid impact and just recently Elon
Musk just leaked a planetary defense that will shock everyone hello everyone welcome
back to Elon Musk Evolution where we bring you the most recent news about Elon Musk and his
multi-billion dollar companies space news and the latest science and technology but before
we begin make sure you subscribe to our Channel and click the Bell icon so you don't miss any of
our amazing videos according to Elon Musk there is no defense against the asteroid God of Chaos
in 10 years Apophis also referred to as the god of chaos asteroid will approach Earth One in 45
000 chances exist that the 340 meter asteroid will collide with the Earth head on on the other hand
as it passes past it will come as close as 30 000 kilometers to the Earth's surface the effects will
be catastrophic if the god of of chaos decides to move even little the aftermath will be much
worse than any other asteroid impact on Earth in recorded human history it may only be a matter
of time until an asteroid strikes Earth according to scientists Elon Musk is the most recent person
to get on the bandwagon in response to God of chaos he declared Earth will eventually be hit
by a large Rock and we currently have no defense he's not mistaken NASA is working to research and
Safeguard Earth from potentially hazardous asteroids however it does not actually have
mechanisms in place to protect the planet in the event that an asteroid is headed straight for it
NASA only recently made public its first planetary defense technology demonstration the space
agency's first mission to show off its defense strategies is the double asteroid redirection test
the majority of people are typically concerned with how an asteroid will affect Earth however
few consider the influence that Earth might have on an asteroid for example the repercussions of a
close encounter with Earth won't be resistant to the god of Chaos according to researchers at Nasa
the planet's gravitational field will undoubtedly have an effect on an asteroid's orbit and may
alter the way Apophis rotates apophysis surface could shift due to the gravitational attraction
which is interesting enough and an avalanche could occur on the other hand more than four
years after NASA's Dart probe collided with one of the asteroids system didymus's two space rocks the
European space agency's her emission will reach the binary asteroid system the didymus pair will
become the most extensively examined space rocks in the universe by the time all the dust produced
by the experimental Collision has settled Hera and its two companion cubesats will be able to do this
with the help of the experimental Collision before NASA's Dart which collided with the
asteroid moonlit dimorphous on September 26 Hera or its precursor concept aim for asteroid impact
mission was supposed to arrive at didymus Hera was intended to be a witness to the groundbreaking
experiment which was created to confirm the kinetic impact technology that one day might
protect Earth from a catastrophic asteroid attack Hera was outfitted with a complex set of cameras
and sensors Hera which cost 280 million dollars was unable to fulfill that job due to Esa approval
delays and a financing decision made too late the tiny lysia cube cubesat made in Italy stepped in
to fill its place however according to experts Hera still has a lot to offer even in late 2026
when didimus is anticipated to receive it after a launch in 2024. they contend that the study would
be lacking and there would be a lot of unanswered questions if Hera's measurements weren't used and
in order to completely validate the kinetic impact technique in the event that it ever
needs to be used to prevent an asteroid strike on Earth these questions must be addressed Michael
keppers the Hera project scientist at the esa stated in a news conference on September 15 that
Hera will measure the mass of dimorphos which will provide a more precise assessment of how effective
this method was in diverting the asteroid it will also describe the two asteroids physical
characteristics like their strength and porosity which will make it easier to extrapolate the dart
data to other asteroids should we ever need to use this method to prevent a catastrophe on Earth
currently the didymus system is being observed by hundreds of ground-based telescopes in an effort
to ascertain how much the dart Collision changed the orbit of the 534 foot wide dimorphous around
the 0.5 mile wide didymus the observations are being supported by NASA's James Webb and Hubble
the two strongest space telescopes even though they were shot from a great distance away the
tiny Lucia Cube has already given photographs of the collision and its immediate aftermath the near
flyby of dimorphous that Lucia cube made in the moments following the dart impact marked the end
of its official science Mission even though the cubesat's two comparatively entry-level cameras
have limitations they may be able to perform more in the coming weeks Patrick Michelle Chief
investigator for Hera at Cote desert University in France remarked during the esa news conference
that dimorphous is a very low gravity environment because it's very small we need a second spaceship
detective to visit the scene and provide us with the specifics of the outcome because the crater
can take hours to form due to the low gravity hair will be equipped with a lidar sensor to
precisely map the surfaces of the two asteroids a thermal camera to examine the surface's chemical
composition and an optical camera that will allow researchers to see both the didymus Untouched by
impact and the final impact crater likewise Harrow will be accompanied on its voyage by two cubesats
named Juventus and Milani that are outfitted with extra Cutting Edge Equipment according
to Esa Juventus will be equipped with a unique low frequency radar instrument that will allow
it to look into the two asteroids and conduct a thorough x-ray inspection Milani will examine
the asteroid's dust and conduct near infrared surface investigations in order to track the
features that affect the outcome of the Collision Michelle added it will be the first time that we
probe the internal properties and subsurface of an asteroid we also intend to use at least one of the
two cubesats to land on the asteroid surface which will provide us with a wealth of new information
according to Michelle scientist will have the three crucial parameters to completely comprehend
the effects of the experiment thanks to images captured just before the impact of dark's own
Draco camera lysia cubes observations of the crash and its immediate aftermath and Hera's
detailed analysis of the longer term outcomes and just recently the esa's hair mission is getting
closer to taking off thanks to the completion of ground tests for a tiny device that can gauge in
asteroid's gravity levels in September 2022 NASA's Dart collided with an asteroid Hera will complete
the first post-impact survey of the asteroid and the gravameter for small solar system objects is
a tiny instrument that will be transported by Hera to determine the minuscule gravity levels
of dimorphous the orbiting moonlit of these 65 803 didymus binary system the launch of grass
one of the key components of Hera is planned for October 2024 with a meeting with dimorphis
plan for December 2026 grass will function in conjunction with the other instruments
to provide a clear picture of the impact caused by Dart this follow-up mission is a component of
the asteroid impact and deflection assessment a global partnership with the goals of testing
kinetic impact as the type of planetary defense against near-earth objects through Dart and giving
reliable data from the impact with Hera what is grass the purpose of the tiny grass payload which
weighs just under 400 grams is to measure the precise mass of the dimorphous asteroid as well as
the anticipated gravity levels one of Hera's two shoebox sized cubesats Juventus which is smaller
of the two carries the payload the gravimeter which is shaped like an L is described by Esa
as being the size of two iPhones joined together the payload was created by the Royal Observatory
of Belgium and the Spanish company and mixes which was in charge of producing its electronics and
mechanical integration although grass is small it is jam-packed with intricate mechanical components
and electronics according to Jose Carrasco CEO of emixis Juventus will be launched and slowly fall
into the surface of the asteroid once Hera has finished the subsurface radar mapping campaign
of dimorphous the Collision on the asteroid any subsequent bounces and any changes in surface
gravity over time brought on by didymus will all be captured by grass during this descent according
to the esa grass will start working to measure the gravitational attraction of the asteroid and thus
picturing its mass distribution while it falls lands after some rebounds and sits still on the
surface of the asteroid Carrasco said in a report it will be in the final falling phase that grass
will start working to measure the gravitational attraction of the asteroid a thousandth of a
millimeter or the sensitivity of one micrometer is all that the gravimeter needs to detect the
tiniest movement two tiny masses are attached to two beams that are orthogonally positioned
to one another and rotate around once per minute in Grass Carrasco went on to say that the slight
displacements of these beams and the mass may be used to reconstitute gravity in three dimensions
Juventus will measure the gravity field from several distinct places during its free fall over
dimorphous which will follow a bent trajectory prior to impact and as a result may be able to
recreate the asteroid's mass distribution the haremition is particularly intriguing since it
will be the first probe to collide with a pair of asteroid bodies and because it will be the
tiniest planet ever discovered by a spacecraft the asteroid which has a diameter of 160 meters may be
modest in comparison to other planetary objects yet it is comparable in size to Egypt's Great
Pyramid of Giza dimorphoses orbital period around didymus was shortened by 32 minutes as a result of
dart's collision with the asteroid which was one of the collision's most severe effects according
to Hannah Goldberg a Hera system engineer the Hera probe will be able to characterize further
changes like these and transform the kinetic impact experiment into a well understood and
in principle repeatable method of planetary defense asteroid framing camera thermal infrared
imager planetary altimeter hyperscout hyper spectral imager and the two cubesats Milani
and Juventus are just a few of the instruments that are housed on Hera testing the space device
at the netherlands-based esa mechanical systems laboratory where the organization evaluates its
smaller scale equipment grass was put to the test before launch to make sure it can
resist the harsh conditions of space according to Carrasco we expect the instrument to function as
it was intended when it is released because Esa has made an intensive test campaign including
vibration radiation and thermal excursions from -35 degrees up to 55 degrees Celsius to ensure
that the instrument is able to withstand the environment that exists around the asteroid in a
thermal vacuum chamber grass underwent space-like vacuum and temperature extreme testing as well as
prolonged shaking to mimic the violence of a rocket launch according to Esa however our lab
testing in conjunction with numerical simulations indicated that we have reached adequate height
sensitivity to detect such low gravity according to zugur karatekin from Rob obviously the real
world performance of the gravimeter cannot be demonstrated directly here on Earth but our
testing coupled with numerical simulations showed we have achieved sufficient High sensitivity to
detect such low gravity he added Carrasco insisted that since emixis was picked for
the project in 2016 there have only been a few minor adjustments that the business has needed
to make however there are still some difficulties to overcome fitting everything into such a compact
volume was the primary challenge according to Carrasco the extremely tiny displacement is
measured extremely extremely tiny electrical currents the most difficult part of making it
was making it mechanically very small and making it measure very little electrical currents grass
will dose off for the duration of Hera's trip to the asteroid in order to ensure that the system
is still functioning properly Carrasco said ground Personnel would reposition the gadget
every few months notably its Motors because they might become stuck if left idle for an
extended length of time the internal battery of the cubesat will let grass operate for up to 20
hours according to karateken from Rob who also added that while Juventus might land anywhere
on dimorphous its solar arrays may be prevented from producing more power likewise kiratika noted
that because the instrument's two gravimeters were angled at right angles to one another and
continue to rotate it is able to generate a 3D gravity vector and track changes in it
from any position during Landing using asteroid deflectors to protect the planet the number of
nearby asteroids that have been cataloged is just 40 percent despite NASA's claim that no
asteroid larger than 140 meters will constitute a hazard to the Earth in the next 100 years in
the Euro federal district of Russia close to Chelyabinsk a meteor with a diameter of 17
to 20 meters collided in February 2013. around 1500 people were hurt however no one died as a
result of the shock wave this incident served as a wake-up call for the need to develop stronger
planetary defense plans and just three years later in 2016 the planetary defense coordination office
was established to catalog NEOS and organize responses to dangers like Dart as a result the
dart spacecraft launched in November 2021 with its first ever full-scale asteroid deflection Mission
it was inevitable that the spacecraft would be destroyed because of the Collision which resulted
in an impact that was comparable to three tons of TNT but other countries are working on methods to
counter potential risks to the globe besides the US and Europe China chose Neo 2019 vl5 in April
of this year for a 2025 launch for a deflection and observation test that will include both a
considerably smaller asteroid than dimorphous will be the target of the Expedition which will Now
launch a year earlier than originally planned the integration of grass with Juventus by the
end of this year would be the next step after Hera's critical design assessment at the end of
2022 because we were able to create a highly sensitive instrument that will fly into deep
space and examine a small body of the solar system this Mission represents a significant advancement
for emixis according to Carrasco the employment of this answer in upcoming missions to research
the Solar System's components and create models of their mass and composition is very likely likewise
Hera might also reveal to us the aesthetic scars the collision with dart Left Behind it's possible
that the impactor simply left a crater on the asteroid or that it violently shook it rearranging
a significant portion of its surface according to Andy Chang an astronomer at the Johns Hopkins
Applied Physics laboratory who worked on Dart a lot of us are wondering how much of the surface
will even be able to recognize the issue according to Michelle is that unless humans send an observer
to the asteroid we won't know what surprises may be waiting for us there the inside of dimorphous
at the time of dart's impact determines what the asteroid's appearance looks like today
if the asteroid was significantly Modified by the spaceship this indicates that the target's
interior was only loosely held together and as of right now according to Tarik daily an astronomer
at the Johns Hopkins Advanced Physics laboratory and member of the dart team we really have no clue
what's happening inside Harrow will attempt to scan beneath the Stony surface alongside
the Juventus which is equipped with radar Hera won't be able to keep an eye on everything of
course dimorphoses ejecta the debris that the asteroid hurled up when dark collided has drawn
the attention of numerous astronomers who are trying to determine how precisely the asteroid
was nudged by the impact most of the ejecta will have vanished by the time Hera shows up
which will be at least four years after the disaster however by learning more about the
inside of the asteroid astronomers can better comprehend the origin of the ejecta and what
might occur if we came into contact with another space Rock in the future Jan Yang Li an astronomer
at Pennsylvania State University who worked on Dart explains that if this technology were to
be used to deflect an asteroid in the future we could conduct a more precise prediction to hit
it dimorphous might not appear the same in 2026 for other reasons as well didymus's gravity May
interact with its smaller companion in a manner similar to how the moon pushes and pulls the
tides in and out of the oceans of Earth these forces may take dimorphous to Veer off course
in its orbit according to scientists but once more until Hera really approaches they won't be
able to see anything of this they may be able to at least establish a baseline as the mission goes
on several of dimorphoses potential future orbits can be virtually recreated by astronomers on Earth
according to Michelle we arrived four years later Michelle continues is not really a problem we are
equipped with the knowledge to determine whether something evolved astronomers will undoubtedly
gain a better understanding of asteroids in both their pre and post-coalition phases thanks to the
information gathered by Hera's eyes and dart's impact they'll assist us in avoiding the Specter
of Death from Above though in keeping with the dinosaur's fear of being destroyed from space
humans have harbored this anxiety for a very long time with the development of Dart the science
of planetary defense took a first step towards practical applications it's difficult to determine
when we'll need the capability to deflect a space Rock because according to astronomers predictions
No Object larger than a kilometer is expected to pass Earth in The Next Century however Michelle
claims that only 60 percent of the things passing by that are at least 40 meters long large enough
to completely destroy a region or a small country have been discovered by satellite organizations
Michelle states that we cannot improvise since we know that eventually such an impact with Earth
will happen again having said that are we capable of deflecting a massive asteroid off its course
or is it only right to consider what Elon Musk is suggesting that we must be a multi-planetary
species in either case we hope for the success of the Starship this will definitely revolutionize
