Russia, NASA agree to continue joint ISS flights until 2025

December 28, 2023

Russian and US space agencies have agreed to keep working
together to deliver crews to the International Space Station
(ISS) until at least 2025, Russian corporation Roscosmos said

The space sector—including its so-called cross-flights that
involve sending crews from different nationalities on one
spacecraft—is a rare area of cooperation remaining between Moscow
and Washington since Russia sent troops to Ukraine.

"An agreement was reached to continue cross-flights until 2025
inclusive," Roscosmos said in a press release.

The decision was taken "to maintain the reliability of the ISS as
a whole," it added.

It also aims "to guarantee the presence of at least one
representative of Roscosmos on the Russian segment and the
presence of at least one representative of NASA on the American

The ISS was launched in 1998 at a time of increased US-Russia
cooperation following the Cold War "Space Race."

ISS partners—the United States, Russia, Europe, Canada and
Japan—are for the moment only committed to operate the orbiting
laboratory until 2024, though US officials have stated they want
to continue until 2030.

Russia said in April that it planned to use the International
Space Station until 2028, an apparent reversal of an earlier
announcement to quit the orbiting laboratory after 2024.

Electric light transmits data 100 times faster than Wi-Fi

by Pohang University of Science and Technology [South Korea]
December 29, 2023

Li-fi, a communication technology harnessing visible light for
data transmission, has a potential to surpass Wi-Fi's speed by
more than 100 times and boasts a high bandwidth, facilitating the
simultaneous transmission of copious information. Notably, Li-fi
ensures robust security by exclusively transmitting data to areas
illuminated by light.

Most important, it capitalizes on existing indoor lighting
infrastructure, such as LEDs, eliminating the need for separate
installations. However, implementing visible light communication
(VLC) in practical lighting systems poses an issue of diminished
stability and accuracy in data transmission.

Recently, a collaborative team led by Professor Dae Sung Chung,
from the Department of Chemical Engineering at Pohang University
of Science and Technology (POSTECH), with researcher Dowan Kim,
Professor Dong-Woo Jee and Hyung-Jun Park from the Department of
Intelligence Semiconductor Engineering at Ajou University, and
Professor Jeong-Hwan Lee from the Department of Materials Science
and Engineering at Inha University, succeeded in utilizing indoor
lighting for wireless communication by reducing light
interference with a novel light source. Their findings were
published in Advanced Materials.

When light of the same wavelength intersects, interference
occurs, resulting in the merging or cancellation of amplitudes.
This phenomenon was observed when using LEDs as a single-color
light source in VLC technology. To overcome this hurdle, the team
developed a novel light source to replace the conventional one.
By combining red, green, and blue organic light-emitting diodes
(OLEDs), they crafted a light source that mimics standard white
illumination but with minimal interference zones.

Furthermore, the team introduced a cavity structure to enhance
the OLED's color representation for each wavelength and
incorporated a Fabry-Pérot structure into the light-absorbing
organic photodiodes (OPDs) to selectively receive specific
wavelengths of light.

The team's composite white light exhibited a significantly lower
bit error rate (BER) than that of conventional light sources.
BER, representing the error ratio to the total transmitted bits,
serves as a key quantifier of digital signal quality. This
remarkable achievement signifies effective suppression of
interference among light sources, ensuring accurate information

Professor Dae Sung Chung, the leader of the consortium,
explained, "In contrast to conventional light sources, our light
source, which blends three wavelengths, circumvents interference
thereby enhancing stability and accuracy in data transmission. We
foresee this technology as a potentially beneficial tool for
diverse industries, serving as a next-generation wireless
communication solution that utilizes conventional lighting

In a multichannel VLC system, mixed white light is created by
using red, green, and blue OLEDs with non-overlapping wavelengths
to minimize interference among channels. The system utilizes OPDs
that selectively absorb the light.

     SWRG#336 closing song:


     The Smothers Brothers, consisting of Thomas (February 2, 1937 – December 26, 2023)[1] and Richard (born November 20, 1938), were American folk singers, musicians, and comedians.

     The brothers' trademark double act was performing folk songs (Tommy on acoustic guitar, Dick on double bass), which usually led to arguments between them. Tommy's signature line was "Mom always liked you best!"

     Tommy (the elder of the two) acted "slow" and Dick, the straight man, acted "superior".
