NASA's New Horizons to continue exploring outer solar system

Tricia Talbert, NASA
October 2, 2023

NASA has announced an updated plan to continue New Horizons'
mission of exploration of the outer solar system.

Beginning in fiscal year 2025, New Horizons will focus on
gathering unique heliophysics data, which can be readily obtained
during an extended, low-activity mode of operations.

While the science community is not currently aware of any
reachable Kuiper Belt object, this new path allows for the
possibility of using the spacecraft for a future close flyby of
such an object, should one be identified. It also will enable the
spacecraft to preserve fuel and reduce operational complexity
while a search is conducted for a compelling flyby candidate.

"The New Horizons mission has a unique position in our solar
system to answer important questions about our heliosphere and
provide extraordinary opportunities for multidisciplinary science
for NASA and the scientific community," said Nicola Fox,
associate administrator for NASA's Science Mission Directorate in
Washington. "The agency decided that it was best to extend
operations for New Horizons until the spacecraft exits the Kuiper
Belt, which is expected in 2028 through 2029."

This new, extended mission will be primarily funded by NASA's
Planetary Science Division and jointly managed by NASA's
Heliophysics and Planetary Science Divisions.

NASA will assess the budget impact of continuing the New Horizons
mission so far beyond its original plan of exploration. As a
starting point, funding within the New Frontiers program
(including science research and data analysis) will be rebalanced
to accommodate extended New Horizons operations, and future
projects may be impacted.

Launched on January 18, 2006, NASA's New Horizons spacecraft has
helped scientists understand worlds at the edge of our solar
system by visiting the dwarf planet Pluto (its primary mission)
and then venturing farther out for a flyby of the Kuiper belt
object Arrokoth, a double-lobed relic of the formation of our
solar system, and other more remote observations of similar

Researchers confirm possibility of wireless communication 40m

by National Research Council of Science & Technology
(Republic of Korea)
September 27, 2023

South Korean researchers have made a discovery that enables
wireless communication below the Earth's surface, a significant
departure from their traditional focus on terrestrial
communication systems. This development opens new avenues for
confirming the survival of individuals trapped due to accidents
such as mine collapses during rescue operations.

The Electronics and Telecommunications Research Institute (ETRI)
announced that they have successfully developed the world's first
"Subterranean Magnetic Field Communication Core Technology."
Utilizing a transmitting antenna with a diameter of 1 meter and a
receiving antenna of several centimeters, the institute managed
to send and receive voice signal-level capacity up to 40 meters
below the Earth's surface in a mine.

Conventional wisdom held that wireless communication in the
complex underground environments of mines was virtually
impossible due to signal attenuation. However, ETRI overcame
these obstacles by developing a new communication system that
leverages the unique boundary conditions of magnetic fields
within the medium. The result is a successful transmission of
voice data-level capacity in a mine where stable communication
was previously unfeasible.

The research team miniaturized the size of their transmitting
antenna to 1 meter, contrasting with the tens-of-meters scale
antennas used in previous international research. The system also
features small receiving sensors based on magnetic induction,
with dimensions in the order of centimeters.

According to the researchers, the newly developed transmitting
and receiving antennas function akin to an Access Point (AP),
essentially serving as a base station linking the surface and the
underground. Therefore, it is expected that once transmitting
devices on the surface and receiving devices underground are
installed, individuals awaiting rescue could communicate through
personal devices like mobile phones, connected to these antennas.

The successful communication test was conducted over a distance
of 40 meters inside a mine composed of limestone bedrock. The
team explained that they used a very narrow low-frequency band of
20kHz, rather than the MHz or GHz range commonly used in general
wireless communication. This frequency band was chosen to
minimize material loss in the subterranean or underwater
environment, and to suit the size of the antennas. The data
transmission rate for voice signals was maintained at around
4kbps, sufficient for basic two-way communication.

In the labyrinthine darkness of underground mines, which bear a
resemblance to the complexity of an ant colony, researchers have
demonstrated the ability to transmit data directly over a
distance of 40 meters between various levels.

This successful application of magnetic field communication
promises to bring substantial changes to the underground mining
industry. Notably, this technology is expected to offer a
reliable mode of communication during emergencies such as mine
collapses, underground fires, and other disaster scenarios that
typically disrupt conventional communication systems.

ETRI emphasized that magnetic field communication systems would
maintain connections between miners and rescue teams during
accidents, thereby facilitating better-coordinated rescue
efforts. The technology is also seen as a means to reduce
response time in emergencies and to enhance safety measures.

Additionally, Last year, they successfully executed underwater
communications up to a depth of 40 meters in freshwater regions
such as rivers and streams.

Moreover, the institute has completed patent applications for key
technologies, including transceivers, related antennas, modems,
bandwidth extension transmission technology, and miniaturized
magnetic field sensors.

ETRI's In-kui Cho, Director of EM Wave Basic Technology Research
Section, said, "We have conducted successful communication trials
between the first and second layers of underground mines using
magnetic field communication systems. This greatly reduces the
likelihood of communication network disruptions caused by mine

Seung-keun Park Assistane Vice President of Radio Research
Division at ETRI, also expressed that beyond mining, magnetic
field communication is expected to have a broad impact across
various sectors. "This technology is anticipated to be a
groundbreaking mode of reliable communication in complex and
unpredictable environments like underground construction,
tunneling, and ocean excavation," he said.

The research team has secured a solid track record, including 10
papers published in SCI-indexed journals and 12 international
patent applications. Their work was presented at the 20th Annual
IEEE International Conference on Sensing, Communication, and
Networking (SECON 2023), held September 12, 2023.

ETRI is concentrating its research on overcoming the limitations
of propagating material in extreme conditions like underwater and
subterranean environments. Collaborating with industry partners,
they aim to further develop this technology for long-distance and
miniaturized systems exceeding 100 meters.

Researchers anticipate that this breakthrough will offer
effective communication solutions not only in mine collapses but
also in other underground structures like gas and oil pipelines,
contributing to increased safety measures during various
