(03:29):
of a Houston habitat that herald ourgiant leap toward the unknowns of deep space.
The frontier of space exploration continues toexpand with NASA's recent unveiling of a
powerful sub kilowatt propulsion technology. Thisis not just another step forward, it's
a substantial leap in enhancing the capabilitiesof small spacecraft. Picture this innovation as

(03:52):
the gateway for a new era ofplanetary exploration missions, where the vastness of
our Solar system becomes ever more accessible. So what's the big deal about this
propulsion system, called the NASA Hseventy one m hal Effect Thruster, its
proficiency in low power operation and highpropellant throughput represents a game changer. It's
designed to execute high delta five maneuvers, the complex navigational feats essential for spacecraft

(04:16):
to escape planetary gravities or smoothly enterforeign orbits. What's truly impressive about this
advancement is how it paves the wayfor small spacecraft to independently journey from Earth's

(05:02):
will be integrated into small spacecraft toprovide extended mission duration for satellites already launched
into space. The implications of thisare profound for the future of space exploration,
increasing not only our capacity to reachdistant worlds, but also understanding our
place within them. As we celebratethis technological triumph, we also recognize the

(05:24):
monumental strides we are making towards becomingan interplanetary species. China is racing towards
a landmark achievement with the upcoming launchof the Chang six spacecraft on May third,
Engineered for the daunting task of returninglunar samples from the far side of
the Moon. This challenging mission,poised for liftoff atop the mighty long March

(05:46):
five rocket, seeks to conquer afrontier never before touched by human technology.
Change six is part of a continuumof ambitious lunar exploration that China has embarked
upon, and if successful, itwill be the first mission to bring back
materials from this largely unexplored region.The South Pole Aitken Basin, a vast
and complex impact structure on the Moon'sfar side, awaits the touchdown of the

(06:10):
sophisticated probe. The mission's four keycomponents, an orbiter, lander, ascender,
and re entry module, are allset for this intricate operation. Upon
landing, Chang's six will deploy botha scoop and a drill to collect invaluable
samples of dust and rock, promisingto shed light on the Moon's secretive pharside
characteristics and the broader chronicles of SolarSystem history. The orchestration of this mission

(06:32):
demands precision, considering the unique challengesof communicating and navigating on the lunar far
side without direct line of sight toEarth. This endeavor is not just a
testament to China's growing prowess in spaceexploration, but also a dynamic shift in
our understanding of Earth's closest celestial neighbor. As we await the data and discoveries

(06:53):
that Changai six will deliver. Westand on the precipice of deepening our knowledge
of lunar geology and the ancient eventsthat shape the heavenly bodies orbiting our Sun.
The Astronomy Daily podcast. Amidst thetumultuous theater of our solar system,
the Sun commands center stage with aperformance that can impact our interplanetary ambitions significantly,

(07:17):
particularly those focused on Mars. Thestar at the heart of our system
is reaching the crescendo of its cycle, a period known as solar maximum,
approximately every eleven years. Our vigilantscouts, the spacecraft orbiting the red planet,
are poised to capture data on howthis peak in solar activity unleashes a

(07:39):
spectrum of solar flares and coronal massejections deep into space, events collectively known
as solar storms. Now, whydoes this matter for our crimson neighbor.
Unlike Earth's robust magnetic fields that wrapour world in a protective embrace, shielding
us from these tempestuous solar outbursts,Mars presents a stark contrast. Its once

(08:00):
global magnetic field is long gone,exposing it to the Sun's energetic whims.
The intrigue lies in understanding the fullpotency of these celestial disturbances at Mars,
knowledge we must grasp before we sendastronauts to walk upon its regalith. NASA's
Maven orbiter observes from its high vantagepoint, measuring radiation, charged particles,

(08:22):
and other phenomena to comprehend these spaceweather events. But understanding the interplay of
radiation with Mars's thin atmosphere requires corroboratingviews from ground level, and that's where
the Curiosity Rovers Radiation Assessment Detector orray D provides critical data from the Martian
surface. Together, these robotic explorershelp us foreshadow the protective measures future human

(08:46):
missions would need against solar radiation's invisiblesiege. This pursuit is not only about
astronauts safety. Investigating solar maximum periodscould offer clues to a long standing mystery
what transformed Mars from a once warm, Earth like oasis into the frigid,
dry world we're exploring today. Itis conceivable that intense solar and dust storm

(09:07):
events through the ages conspired to stripaway the Martian atmosphere and its water,
leading to its current arid state.Observing Mars now gives scientists the chance to
capture this complex atmospheric interplay at work, and perhaps unlock the secrets of the
planet's drastic climate change. As westand on the threshold of human exploration of

(09:28):
Mars, understanding the solar phenomena isnot a scientific indulgence, but a necessity.
It is the muse of caution,singing to those daring to dream of
stepping onto alien sands, reminding usthat the journey to other worlds is paved
with more than just technology and ambition. It also requires the wisdom to respect
and prepare for the cosmic forces wewill face. Imagine sending a text message

(09:54):
or making a call from the Moon'ssurface. This may soon be a reality,
as no Nokia is taking bold stepsin developing a four G slash LTE
network on our lunar neighbor. Ina pioneering move. Hardware earmarked for a
simplified version of this network is setto launch later this year aboard the Intuitive
Machine's IM two mission targeting the Moon'ssouth pole. This project entails a compact

(10:18):
network in a box that will bindtogether the Nova SA Lunar Lander, lunar
outposts map rover and intuitive machines microNOVAHopper in a bid to validate the network's
capacity across various lunar distances. Thenotion is simple yet transformative. Treat the
Moon like Earth, linking billions ofpotential devices just as we do at home.

(10:39):
In twenty twenty, as part ofthe Artemis program, NASA recognized Nokia's
vision with a fourteen point one milliondollars contract, the goal to create the
first lunar cellular network by reinventing terrestrialtechnology to withstand the rigors of the Moon's
environment. If successful, this networkwill not only streamline astronaut communication, but

(11:01):
will empower robotic systems with efficient autonomy, signaling a leap in our capacities for
lunar exploration and resident habitation. Thepromises of this technology are boundless, from
increased bandwidth eclipsing conventional space communication systems, to a pre paved path for Mars
communication framework, perhaps even an upgradeto five G. Nokia's innovation is meticulously

(11:24):
laying the groundwork for the next twodecades of lunar operations. As we face
the potential of moon bases and manifoldmissions, it is crucial for a unified,
economically sensible infrastructure to support this extraterrestrialexpansion, and if Nokia navigates this
right, they could provide the backbonethat sustains future lunar civilization. That's today's
