Stratospheric balloons listen in on ground activity

by J. Lee, American Geophysical Union
November 16, 2021

Earthquakes, volcanic eruptions, and even severe weather events
produce a medley of low-frequency infrasound waves below the
range of human hearing. Researchers can investigate these sounds
to gain a deeper understanding of our planet. In addition to
natural events, infrasound sensors can pick up events caused by
human activity, from city noise to nuclear explosions.

As part of a larger research team, Bowman and Krishnamoorthy
detonated a canister located about 50 meters below the ground
that was filled with an explosive equivalent to 10 tons of
2,4,6-trinitrotoluene (TNT). A network of instruments on the
ground - including accelerometers, seismometers, and
microbarometers - recorded ground shaking and pressure waves from
the explosion. Ground sensors picked up the pressure waves 12
kilometers from the blast, but another array about 46 kilometers
away heard nothing.

By contrast, the researchers report, microbarometers carried by
solar-powered hot-air balloons in the lower stratosphere, over 20
kilometers above Earth's surface, detected infrasound signals
from the buried chemical explosion. The researchers propose that
the balloon-borne microbarometers detected a strong signal
because the troposphere directs sound upward. In addition, the
sensors would have bypassed background noise and sound-scattering
features on the ground.

The new study supports further use of balloon-borne
microbarometers for investigating geophysical activity and
monitoring explosions on Earth. The results also support mission
concepts proposing to use balloons to explore Venus and
investigate volcanic activity and venusquakes via infrasound.

Going to Mars is hard: Lessons from Mariner 9

By David Szondy
November 12, 2021

Fifty years ago, on November 14, 1971, NASA's robotic Mariner 9
probe went into orbit around Mars. This was not only the first
time a spacecraft orbited another planet, but also one of the few
early missions to avoid the infamous Curse of Mars.

There are currently 13 uncrewed missions operating on the surface
of, or in orbit around, the Red Planet, making it the solar
system equivalent of Piccadilly Circus. This is both a remarkable
technological achievement and the basis for widespread

In the public imagination, Mars has become increasingly regarded
as a benign place, and getting to it is as routine as a
transoceanic flight. As a result, people talk casually about
colonizing Mars as a relatively simple matter, something that
could be accomplished in a couple of years if only the money and
the will was available.

The reality is far harsher. Mars is an extremely hostile place by
Earth standards. Aside from an incredibly thin atmosphere,
corrosive soil, freezing temperatures, no protection against UV
or cosmic radiation, and a lack of water that makes the Atacama
Desert look like the Garden of Eden, just getting to the planet
is still so hazardous that every arrival is greeted by space
engineers with a sincere sigh of relief.

Despite this, it's surprising how quickly the first missions to
Mars were launched. The first artificial satellite was launched
into Earth orbit by the Soviet Union in 1957, and on October 10,
1960 with the Mars 1M No. 1. it was already sending up its first
Mars probe – although it never reached orbit.

The reasons for this rapid expansion were twofold. First, the
Soviet leaders regarded spaceflight as having little or no
practical value – aside from taking reconnaissance photos of the
West – so space missions were only useful as propaganda stunts
and the space program was expected to chalk up as many firsts as
soon as possible, including getting to Mars.

The second reason is the paradox of space technology. Though the
spacecraft and launchers of the day were primitive by today's
standards, rocket technology was already incredibly advanced by
1960. In fact, by the time that the first German V-2 rockets shot
into space in the 1940s, the engineers were already working at
the theoretical limits of chemical rockets.

This meant that the Soviets and the Americans already had the
rockets to get at least small probes to Mars, but getting there
successfully was another problem. In all, over 50 percent of all
missions over the past 60 years have failed either partly or
completely, a success ratio referred to with only partial humor
as the "Curse of Mars."

By the time Mariner 9 reached Mars, there had already been 20
missions launched. Of these, 15 were failures or partial failures
where the craft stopped operating almost immediately, and five
were successes. Two of these were Soviet missions that launched
before Mariner 9, but arrived after it thanks to the vagaries of
celestial mechanics, and the three NASA probes, Mariners 4, 6 and

Even Mariner 9 was a bit of a crap shoot. Originally, it was
supposed to be a two-spacecraft mission along with Mariner 8, but
that one was destroyed in a launch failure and NASA had to
scramble at the last minute to modify the 997.9-kg (2,200-lb)
Mariner 9 and its Atlas/Centaur booster before its May 30, 1971
launch as a solo mission. Luckily, this launch went off so
smoothly that Mariner 9 was almost exactly on track and didn't
even need a course correction on its journey to Mars.

To add to the uncertainty, the previous Mariner missions had cast
a pall over the entire point of going to Mars. Up until then, the
opinion was that Mars was Earth-like enough that there was a very
good chance that it could sustain some form of life. True, the
old idea it was home to a dying race that survived by using great
canals to bring water from the poles to the equator had been
dismissed, but even when a scientist said that Mars was dead, the
implication was that the planet still could have mosses, lichens,
and maybe grass or even small animals.

If anyone found those today, it would be an automatic Nobel

What now seem like purely sci-fi hopes were dashed by the first
three Mariner probes, which were flyby missions that visited for
only an extremely brief time with very slow, primitive digital
cameras capturing images from a distance of more than 2,000 miles
(3,200 km). These probes passed over the most desolate parts of
Mars, where they sent back pictures of a surface strewn with
craters like those on the Moon. Far from being the home to alien
rodents, Mars looked like a very dead world.

But Mariner 9 had massive surprises in store. At first, Mars was
a frustrating subject for study. A planet-wide dust storm was
raging and the orbiter's computer had to be ordered to shut down
the cameras for months until this cleared. When the clouds
cleared, the probe resumed its survey and with great slowness it
sent back 7,329 images covering 85 percent of the surface
captured over 349 days in orbit. These images had to be printed
out in hard copy and then stitched together by hand.

What the scientists saw revolutionized our ideas about Mars and
in turn the whole field of planetary science. Mars turned out to
be a remarkably dynamic planet, with winds that pushed shifting
dune systems about. There were also signs of geological activity
on a massive scale, some billions of years ago.

The probe's cameras revealed the Valles Marineris canyon system,
named after Mariner 9, which is a giant rift valley that could
swallow the Grand Canyon without a burp. Then there was Olympus
Mons, the largest volcano in the solar system and three times the
size of the largest volcano on Earth. In addition, there were the
great empty sea beds of the Martian plains that stretched for
thousands of miles.

But the most existing discoveries were what looked like ancient
lakes and river beds. There were also flood plains and many other
features that suggested that at one time Mars may have had
abundant water. Water means potential life. If not today, but
maybe sometime in the past. Almost immediately, this re-sparked
public and professional imaginations about Mars.

By the time Mariner 9 had exhausted its supply of propellant for
its attitude thrusters and was shut down on October 27, 1972,
scientists were once again speculating on what kind of life might
be found on Mars and they were updating the planned Viking
landers to include the first experiments aimed at discovering
signs of life on another world.

It's a task that humanity is still pursuing and dreaming about,
even if it means facing the Curse of Mars.
