Public given clearance to explore London's top secret spy tunnels

By Adam Williams
October 11, 2023

Hidden roughly 40 m (131 ft) below central London's streets lies
a fascinating but little-known network of tunnels. Originally
conceived as a bomb shelter during WWII, the Kingsway Exchange
Tunnels were used as a telecommunications center and even a spy
headquarters. Now WilkinsonEyre has revealed plans to open them
up and tell their story to the public.

As mentioned, the Kingsway Exchange Tunnels were originally built
in the 1940s to protect Londoners from Nazi bombs during the
Blitz, plus they also served as a home for the Special Operations
Executive branch of MI6 – indeed, WilkinsonEyre says they
inspired the depiction of James Bond's Q Branch. Following WWII,
they were then expanded upon and hosted a Transatlantic telephone
link, playing a crucial role facilitating the hotline between
Washington and Moscow during the Cuban Missile Crisis.

During its peak, the site accommodated up to 200 staff, supported
by self-contained water and air conditioning systems. It also
boasted some amenities, including a restaurant, what was thought
to be London's deepest licensed bar, and a recreation room
complete with snooker tables. However, by the late 1980s,
telecommunication technology had advanced to the point that the
tunnels were deemed obsolete and they largely remained unused.
WilkinsonEyre says that after 70 years of protection under the
UK's Official Secrets Act, a significant portion of the
underground network will be opened up to the public.

Assuming it goes ahead as planned, the renovation will be focused
on a section of the tunnels that measures a combined length of 1
mile (around 1.6 km) and 8,000 sq m (86,111 sq ft). The tunnels
measure 7.6 m (24 ft) in diameter, or approximately the width of
three London buses, and will be used to host exhibition spaces
and displays, as well as some of the original telecommunications
gear.

"Subject to planning approval, the vision is to transform the
tunnels into one of the world's most unique cultural
experiences," explained WilkinsonEyre. "It will bring to life the
history of the tunnels by installing high-resolution large-scale
curved immersive screens, together with interactive structures,
scent- emitting technology and hundreds of individual acoustic
pinpoint speakers. With an operational capacity of two million
visitors per year, the tunnels could also host different
experiences in partnership with major entertainment businesses,
artists, performers and curators."

The London Tunnels proposal has been unveiled as part of a public
consultation program to gather feedback before a planning
application is officially submitted later this year. It has a
budget of £220 million (roughly US$270 million) and is expected
to open in 2027.

From Futurity.org:

First glimpse of asteroid Bennu samples reveals carbon, water

October 13th, 2023
Posted by U. Arizona

Initial studies of the 4.5-billion-year-old asteroid Bennu sample
collected in space and recently brought back to Earth show
evidence of water and high-carbon content.

Together, they could indicate the building blocks of life on
Earth may be found in the rock.

NASA announced the finding October 11 from its Johnson Space
Center in Houston, where scientists showed off the asteroid
material for the first time since it landed in the Utah desert on
September 24. The finding was part of a preliminary assessment of
the OSIRIS-REx science team.

"As we peer into the ancient secrets preserved within the dust
and rocks of asteroid Bennu, we are unlocking a time capsule that
offers us profound insights into the origins of our solar
system," says Dante Lauretta, professor of planetary sciences at
the University of Arizona and OSIRIS-REx principal investigator.

"The bounty of carbon-rich material and the abundant presence of
water-bearing clay minerals are just the tip of the cosmic
iceberg. These discoveries, made possible through years of
dedicated collaboration and cutting-edge science, propel us on a
journey to understand not only our celestial neighborhood but
also the potential for life's beginnings. With each revelation
from Bennu, we draw closer to unraveling the mysteries of our
cosmic heritage."

One of the core questions driving the mission is understanding
the origin of Earth as a habitable planet, Lauretta says, and the
current understanding of what makes a world habitable is abundant
liquid water on the surface, such as the Earth's oceans and
freshwater supplies.

"When Earth formed, especially after the giant impact that spun
off the moon, the water and carbon were lost from our planet, so
we're looking to figure out, 'How did we get that material
back?'" Lauretta says. "Our leading hypothesis is that asteroids
rich in carbon and water came in later and delivered the
essential building blocks of life, made the Earth a habitable
world, and the rest is history."

Although more work is needed to understand the nature of the
carbon compounds found, the initial discovery bodes well for
future analyses of the asteroid Bennu sample. The secrets held
within the rocks and dust from the asteroid will be studied for
decades to come, offering insights into how our solar system was
formed, how the precursor materials to life may have been seeded
on Earth, and what precautions need to be taken to avoid asteroid
collisions with our home planet.

"The OSIRIS-REx sample is the biggest carbon-rich asteroid sample
ever delivered to Earth and will help scientists investigate the
origins of life on our own planet for generations to come," says
Bill Nelson, NASA Administrator.

"Almost everything we do at NASA seeks to answer questions about
who we are and where we come from. NASA missions like OSIRIS-REx
will improve our understanding of asteroids that could threaten
Earth while giving us a glimpse into what lies beyond. The sample
has made it back to Earth, but there is still so much science to
come—science like we've never seen before."

The goal of the OSIRIS-REx sample collection was 60 grams of
asteroid material. Curation experts at NASA Johnson, working in
new clean rooms built especially for the mission, have spent 10
days so far carefully disassembling the sample return hardware to
obtain a glimpse at the bulk sample within.

When the science canister lid was first opened, scientists
discovered bonus asteroid material covering the outside of the
collector head, canister lid, and base. There was so much extra
material it slowed down the careful process of collecting and
containing the primary sample.

"Our labs were ready for whatever Bennu had in store for us,"
says Vanessa Wyche, director of NASA Johnson. "We've had
scientists and engineers working side-by-side for years to
develop specialized gloveboxes and tools to keep the asteroid
material pristine and to curate the samples so researchers now
and decades from now can study this precious gift from the
cosmos."

Within the first two weeks, scientists performed "quick-look"
analyses of that initial material, collecting images from a
scanning electron microscope, infrared measurements, X-ray
diffraction, and chemical element analysis. X-ray computed
tomography was also used to produce a 3D computer model of one of
the particles, highlighting its diverse interior. This early
glimpse provided the evidence of abundant carbon and water in the
sample.

For the next two years, the mission's science team will continue
characterizing the samples and conducting the analysis needed to
meet the mission's science goals. NASA will preserve at least 70%
of the sample at Johnson for further research by scientists
worldwide, including future generations of scientists.

As part of OSIRIS-REx's science program, a cohort of more than
200 scientists around the world will explore the regolith's
properties, including researchers from many US institutions, NASA
partners at the Japan Aerospace Exploration Agency, the Canadian
Space Agency, and other scientists from around the world.

Additional samples will also be loaned later this fall to the
Smithsonian Institution, Space Center Houston, and the University
of Arizona's Alfie Norville Gem & Mineral Museum.
