Russia resumes use of space launch site damaged in accident

March 23, 2026

Russia has launched a rocket from Site 31 of the Baikonur
Cosmodrome for the first time since it was damaged during a
liftoff last November, video from Russia's Roscosmos space agency
showed Sunday.

Site 31 was Russia's only operational launchpad for crewed
missions to the International Space Station (ISS).

Part of the launch site collapsed during liftoff of Soyuz MS-28
in November last year, temporarily preventing Russia from being
able to send cosmonauts into space.

Repairs on the damaged section of the site wrapped up earlier
this month, according to Roscosmos.

Video on Sunday showed Russia launching the unmanned Progress
MS-33 cargo ship to the ISS from Site 31.

"The flight is normal," a commentator on Russia's Roscosmos space
agency said on the video.

The US space agency NASA posted on X that an antenna on Progress
used for docking had not deployed as it was supposed to.

"All other systems are operating as designed, and Progress will
continue toward its planned docking," NASA wrote.

The Baikonur Cosmodrome is located in Kazakhstan, but is being
used by Russia under a lease set to last until at least 2050.

Once considered a pioneer in space exploration, Russia's space
program has faced numerous setbacks since the fall of the Soviet
Union, including the loss of its first lunar lander in almost 50
years in 2023.

From TechXplores.com:

Researchers achieve 100-meter underground wireless communication

by National Research Council of Science and Technology
(South Korea)
March 23, 2026

Korean researchers have confirmed that underground wireless
communication is possible, moving beyond the terrestrial wireless
communication they have primarily focused on until now. This
opened up a new wireless channel for confirming the survival of
buried people in the event of a collapse of an underground
facility such as a mine, conducting underground rescue
operations, or conducting underground military operations.

ETRI has succeeded in developing the world's first "magnetic
field underground communication source technology" that can
transmit and receive voice signals 100 meters underground in a
mine using a 1-meter diameter transmitting antenna and a
several-centimeter-class receiving antenna.

This technology confirms the feasibility of voice transmission
and reception in underground spaces previously inaccessible by
wireless technology. Accordingly, this technology is expected to
be applied in activities such as rescue operations, military
operations, and common utility tunnel safety management.

In particular, this research is based on test results conducted
in a limestone bedrock environment where underground
communication is known to be virtually impossible, and is
considered to have opened up a new area of underground space
communication technology, such as rescue operations and military
operations.

Underground mines have very severe signal attenuation, making
them inaccessible using existing wireless communication
technologies.

ETRI focused on the stable transmission of magnetic fields in
underground media and developed a low-frequency magnetic
field-based communication system.

The researchers implemented communication using a
1-meter-diameter transmitting antenna, a small magnetic field
receiving sensor of several centimeters in size, a frequency of
approximately 15 kHz, and a data rate of 2–4 kbps, which is
sufficient for voice communication.

They successfully conducted bidirectional communication testing
within a 100-meter straight-line distance between the mine
entrance (ground level) and the fifth underground layer. This is
the world's first demonstration that surpasses existing
tens-of-meters-level overseas research.

This outcome signifies the possibility of communication between
buried people and rescue teams in situations such as underground
disasters, including mine collapses.

Also, it can be widely utilized in various fields, such as
responding to disasters in common utility tunnels, gas pipelines,
and oil pipelines, ensuring communication continuity during
military operations in underground bunker environments, and more.

ETRI explained that it is advancing technologies linked to
personal devices such as smartphones, and that this will make
wireless relays (APs) connecting ground and underground possible.

This technology has been described in the IEEE IoT Journal, and
domestic and international patent applications have been
completed for key elements such as the transmitter/receiver,
antenna, low-frequency modem, and bandwidth expansion technology.

Twelve SCI papers in publication, two presentations at
international academic conferences, eight international patents,
and technology transfers were accomplished.

Cho In Kui, Principal Researcher of ETRI's EM Wave Basic
Technology Research Section, stated, "This is a technology that
can significantly reduce the possibility of communication
disruption during rescue operations in the event of a mine
accident, as much as it has succeeded in communication in
underground environments where radio waves do not reach."

Seung Keun Park, Assistant Vice President of ETRI's Radio
Research Division, said, "This is an innovative technology
necessary not only for mines but also for extreme environments
such as tunnels, underground facilities, offshore drilling, and
national defense. It will be utilized in various industrial
sectors as a highly reliable communication means."
