Faulty chip may be clue to Voyager 1 computer fix

By David Szondy
April 9, 2024

NASA engineers have narrowed down the problem with the Voyager 1
deep space probe to a single faulty chip. It may now be possible
to work around the corrupted memory and return the 47-year old
interstellar spacecraft to an operational condition.

Since November, NASA has been trying to repair the Voyager 1
probe, which has been sending back gibberish instead of science
and engineering data. It's hard enough trying to fix a piece of
technology that dates back to the time of paper tape memories.
It's downright frustrating when it's over 15 billion miles (24
billion km) from Earth and it takes two days to get a reply to
any signals sent to it.

Then came the breakthrough on March 1, when one of a long string
of commands was sent trying to get a response from Voyager 1. Two
days later, a string of gibberish came back to Mission Control,
only it was different gibberish that one engineer at NASA's Deep
Space Network recognized and was able to decode.

This turned out to be a dump of the onboard computer's complete
memory that gave NASA engineers vital clues to the problem and
the hope of solving it. It was already known that the trouble was
in the Flight Data Subsystem (FDS), which controls packaging data
for transmission to Earth. Now, the fault has been narrowed down
to a particular chip that may have failed due to old age or being
struck by a cosmic ray particle.

It's now hoped that sometime in the coming weeks or months a way
might be found to bypass the chip. If so, then Voyager 1 can
return to work until its nuclear power source fails completely
sometime in the next few years.

Seafood waste isn't as bad as previously thought

April 10th, 2024
Posted by University of Florida

A new study shows seafood food loss and waste in the United
States is approximately 22.7%, a drastic decrease from previous
estimates of between 43% and 47%.

The study, conducted in part by researchers from the University
of Florida Institute of Food and Agricultural Sciences (UF/IFAS,)
provides an in-depth estimate of food loss and food waste in the
US aquatic foods sectors. Previous estimates came from the Food
and Agriculture Organization of the United Nations.

"The method is the same, but the data are more detailed," says
Frank Asche, professor in the School of Forest, Fisheries, and
Geomatics Sciences and a corresponding author of the study.

"The key is not the differences between the different countries,
but to account for the differences of the species being consumed,
and the parts of the fish are not being exported but are still
being used."

Approximately 80% of seafood consumed in the United States is
imported.

The researchers conducted interviews and collected secondary data
across the United States, Vietnam, Norway, and other primary
producers of seafood consumed in the United States. Looking at a
four-year period from 2014-2018, they estimated food loss and
waste for the top 10 fish species consumed in this country:
shrimp, canned tuna, salmon, Alaska Pollock, tilapia, catfish,
crab, cod, clams, and pangasius, a type of shark catfish native
to Southeast Asia. Previous studies neglected to account for
species and supply chain characteristics.

Beyond providing an overall estimate, researchers identified
where food loss and waste took place in the supply-chain process.
Most happened in the primary production and the final consumption
stages. When it comes to increasing sustainability and food
security, the researchers believe this knowledge helps identify
which areas of the supply chain may be targeted to reduce waste.

"Reducing waste is about more than just harvesting the right
number of fish," says James Anderson, a UF/IFAS food and resource
economics professor and corresponding author of the study. "It's
about harvesting them well and minimizing waste. It's about not
losing quality and quantity in the process."

Aquaculture, or farmed fish, now accounts for about 50% of edible
seafood production globally, and there are opportunities to
improve its resilience from factors such as disease, poor water
quality, and possible pesticide contamination.

"Aquaculture is still in its infancy, so investing in things that
improve its efficiency and reduce losses is reducing waste,"
Anderson says.

The study also evaluated quality loss, a crucial factor in
determining and minimizing food waste. Unlike the physical loss
of a product, quality loss occurs when lower-quality products are
sold for a discounted price, though the product can still able be
used.

The study's findings go beyond providing hope that food security
is better in the aquatic foods industry than previously believed,
according to the researchers. It also offers insight into methods
for further reducing loss, both through regulation and consumer
education.

Most seafood in the United States is purchased at the retail
level and consumed at home, according to the study. Relying on
food diaries, the researchers estimated a physical seafood loss
rate of 8.5% at home. The most common reasons recorded were "did
not want it as leftovers" at 18%, "bought too much" at 16%, and
disinterest due to slimy appearance and odors at 6%.

Consumers' "relatively low proficiency" with handling, storing,
and preparing seafood may lead them to prematurely discard it,
according to the study.

Kim's note: Here in Arlington, Virginia, we have green carts
used for weekly collection of "food scraps, which range from the
remnants of fruits and vegetables to that of dairy and meats,
bones included. Even greasy pizza boxes and paper napkins
qualify." So any wasted seafood joins the other food scraps to
make very rich mulch.
