let's revisit three of this year's
biggest space stories the James Webb
Space Telescope the most powerful Space
Telescope ever built sent back stunning
images of nebulas galaxies close-ups of
Neptune in Jupiter and even chemical
signatures in the atmosphere of an
exoplanet as the first images came in
scientists were blown away
this is an engineering image that was
really there just to say we focused it
right
and
there's a lot of galaxies you know you
know the the engineers were like what
are all those galaxies doing there we're
realizing we're the first people that
have ever seen these galaxies everything
about these images that I've seen so far
tells us absolutely this thing is going
to be fantastic we don't know what we're
gonna see but we know we haven't seen
anything like this before this is going
to be transformative this is looking
amazing I almost have no words you know
because it's it's the feat of
engineering right but it's also
wow our universe is beautiful the great
thing is that really this is just the
beginning today is just the beginning
we'll be able to go much much deeper and
this telescope is going to do what we
designed it to do
jwst's infrared technology can peer
through dense clouds of space dust that
block visible light revealing secrets of
the universe this is the biggest
telescope that has been built in space
and because of the complexity of the
design this is no doubt the most complex
machine and it is magnificent scientists
expect jwst to deliver years of
discoveries about the early Universe in
the first galaxies how stars and planets
evolved and the atmospheres of
exoplanets it's taken us a long time to
get here but man we're so excited this
year NASA put Earth's defense strategy
against dangerous asteroids to the test
we want to know whether or not we will
be able to redirect the master we have a
fantastic team of planetary Defenders
trying to find the near-earth asteroids
that perhaps pose an impact threat in
the first mission of its kind NASA's
Dart spacecraft crashed into an asteroid
in an attempt to change its trajectory
scientists targeted dimorphous a 530
foot diameter asteroid moonlit orbiting
around a larger asteroid called didimus
neither one is considered a danger to
Earth we're testing out a technique
called kinetic impactor about four hours
out before the impact the spacecraft
becomes fully autonomous Point itself
towards the Moon make all the Maneuvers
necessary to slam itself into this
really small object future missions like
like these could potentially deflect
asteroids headed towards Earth it is
very impressive and hard
one of the most anticipated space events
this year was finally launching Artemis
1. the first of NASA's new Artemis
program Artemis 1 tested two deep space
exploration systems including the Orion
spacecraft which splashed down in the
Pacific Ocean on December 11th this Tech
may be used in future missions to send
humans back to the Moon who doesn't want
to go back to the Moon I mean come on
it's a stepping stone to the rest of our
future NASA scientists hoped to
establish a more permanent presence on
the moon and use it as a stepping stone
to explore deeper into space including
Mars we need to go there learn how to
live and work sustainably off Earth a
lot of people would like to go on to
Mars but we have a lot of experience to
get under the belt before we can do that
Journey to Mars in 2023 the space
exploration continues SpaceX plans to
launch the Polaris Dawn Mission which
will include the first commercial
spacewalk and NASA plans to launch the
psyche spacecraft an Orbiter mission
that will explore the asteroids psyche
it sounds like living in a science
fiction movie but we are not living in
that anymore this is science this is
real
