From Radio Free Europe/Radio Liberty:

Russian Cosmonauts Investigate Mysterious Hole In ISS During
Six-Hour Space Walk

12 December 2018

Russia's space agency said two cosmonauts took samples of the
exterior of the International Space Station (ISS) as part of
efforts to resolve the mystery of a small hole found in a Soyuz
spacecraft docked at the station.

The two Russians performed the space walk on December 11, as part
of an effort by Roskosmos to pinpoint the cause of the hole,
which was found in August in the capsule and strained relations
between the Russian and U.S. space agencies.

A live broadcast shown on NASA's website showed Oleg Kononenko
and Sergei Prokopyev trying to cut through insulation of the
spacecraft with a knife, in order to find the external part of
the hole. The materials will be brought back to Earth for further
examination.

The chief of Roskosmos, Dmitry Rogozin, had floated unusual
theories, including that an American astronaut purposely made the
2-millimeter hole in order to return to Earth sooner than
scheduled.

The American commander who was in charge of the station at the
time flatly denied any wrongdoing by himself or his crew.

Rogozin later backpedaled on his statement.

The U.S. space agency NASA, meanwhile, has downplayed the
incident over the puncture, which caused a slight drop in oxygen
but was quickly sealed.

From Radio Canada International:

Canada History: Beginning of radio (maybe), December 12, 1901

Marc Montgomery
12 December 2018

First transatlantic wireless signal

On a chilly windy December 12, in 1901 history was made, or
perhaps "claimed" to have been made.

Italian inventor Guglielmo Marconi said he had received a number
of scratchy clicks on his telegraphy receiving equipment set up
on Signal Hill on the coast of Newfoundland. The clicks-morse
code- were sent through the air without wires. What is unique is
that the signal had been broadcast across the Atlantic Ocean from
Poldhu in Cornwall, England over 3,000 kilometres away.

The repeated sending of the Morse code signal for the letter "S"
was the first wireless trans-Atlantic signal.

Detractors had said such wireless signals could not travel more
than a few hundred kilometres due to the curvature of the Earth,
whereas Marconi believed they would.

Ironically although the signal is alleged to have made it across
the ocean, the detractors were correct. What Marconi and others
at the time could not have understood and what may have happened
was the signal from England was heading to space when it bounced
off the ionosphere and back to earth where Marconi's team, flying
a kite with a 121 metre long copper wire antennae picked it up.
This atmospheric skipping of the signal became known and used
only much later.

However with hefty financial backing he would eventually be able
to send transatlantic signals at a later date and as the concept
of propagation became better understood. Year's later, when
Marconi was awarded the Nobel prize, inventor Nicolas Tesla would
sue over Marconi's use of his patents. It should be noted that
Marconi wireless was used by the Titanic to indicate its distress
and without it, no one would have known and there would have been
no survivors in the vast reaches of the cold mid-Atlantic

Doubt about Marconi's achievement

However, Marconi's original claim is clouded by some skepticism.

Scientists now point out the test took place during the daylight
when medium wave signals are mostly absorbed by the ionosphere
and not "bounced" which would seriously limit their ability to
travel great distances, especially with the low power technology
at the time.

Only later would scientists come to understand the reaction of
radio signals to the atmosphere, and this bounce or reflection of
the signals.

Marconi also knew what signal to listen for, so it was not a
"blind" test, and scientists now say it would have been extremely
difficult for anyone to detect an actual signal from the
background static, especially after a couple of days of listening
to the static.

Also playing against the claim, is the fact that Marconi was the
only one listening so there is no other "witness".

Lurking in the background also was his need for success in order
to raise capital from investors to further his experiments.

Another doubt is raised by the fact his original receiving
antenna was damaged by a storm hence his efforts to use a long
wire and kite, although the wire moving about attached to the
kite would not have made for a stable receptor.

A technical analysis casting doubt on Marconi's claim was made by
radio and electronics expert John Belrose (PhD) in 1995.

Meanwhile, four days after this "miracle" of wireless
transmission, Marconi will be officially notified by the
Anglo-American Telegraph Company that it will take legal action
against him unless he immediately ceases his wireless experiments
and removes his equipment from Newfoundland.

Anglo-American has a fifty-year monopoly on electrical
communications in Newfoundland starting in 1858, and is
determined to hinder radio telegraphy, which it knows is a
serious threat to its transatlantic electric telegraph business
operated by submarine cables. Marconi soon decides to move his
base of operations to Cape Breton in Nova Scotia.

Although often credited with inventing radio, Marconi actually
never saw the need for voice transmission or "radio" as we know
it. In fact he was not dealing with radio in the modern sense,
rather his interest was entirely focused on the commercial
potential of wireless telegraphy.

His limitations of his "spark-gap" technology soon became
evident and efforts to continue and improve it eventually come to
a dead end. He was obliged to abandon the concept in 1912.

Radio's true inventor

Early on, a Canadian inventor Reginald Fessenden has studied the
technology and realize it led nowhere. He rejected Marconi's
spark idea and developed a continuous wave technology which he
felt would transmit Morse more clearly and much more importantly,
also voice.

On Dec 23 1900 he transmitted voice over a distance of 1.5 km.
Over the next few years he continued his research and developed
improved technology.

In 1906 Fessenden sent the world's first true radio broadcast
when he gave a short speech, and played a tune on his violin
which was picked up on US Navy ships, and commercial cargo ships
equipped with Fessenden radio receivers.

In 1925, another Canadian, Edward Rogers (Sr) would invent
another radio breakthrough. Improving on an American invention,
he created a vacuum tube that enabled operating radios on
household electric current, eliminating the heavy, messy, and
corrosive batteries then required. His invention also improved
technology in radio broadcasting and led to the simplicity of
radio operations we know today.

Kim's note: Just as some experts doubt the authenticity of
Marconi's first transatlantic Morse code transmission, others
have doubts about Fessenden's first voice broadcast. See
