British research ship crosses paths with world's largest iceberg
as it drifts out of Antarctica

by Sylvia Hui
December 4, 2023

Britain's polar research ship has crossed paths with the largest
iceberg in the world—a "lucky" encounter that enabled scientists
to collect seawater samples around the colossal berg as it drifts
out of Antarctic waters, the British Antarctic Survey said
Monday.

The RRS Sir David Attenborough, which is on its way to Antarctica
for its first scientific mission, passed the mega iceberg known
as the A23a on Friday near the tip of the Antarctic Peninsula.

The iceberg—equivalent to three times the size of New York City
and more than twice the size of Greater London—had been grounded
for more than three decades in the Weddell Sea after it split
from the Antarctic's Filchner Ice Shelf in 1986.

It began drifting in recent months, and has now moved into the
Southern Ocean, helped by wind and ocean currents. Scientists say
it is now likely to be swept along into "iceberg alley"—a common
route for icebergs to float toward the sub-Antarctic island of
South Georgia.

"It is incredibly lucky that the iceberg's route out of the
Weddell Sea sat directly across our planned path, and that we had
the right team aboard to take advantage of this opportunity,"
said Andrew Meijers, chief scientist aboard the research ship.

"We're fortunate that navigating A23a hasn't had an impact on the
tight timings for our science mission, and it is amazing to see
this huge berg in person—it stretches as far as the eye can see,"
he added.

Laura Taylor, a scientist working on the ship, said the team took
samples of ocean surface waters around the iceberg's route to
help determine what life could form around it and how the iceberg
and others like it impact carbon in the ocean.

"We know that these giant icebergs can provide nutrients to the
waters they pass through, creating thriving ecosystems in
otherwise less productive areas. What we don't know is what
difference particular icebergs, their scale, and their origins
can make to that process," she said.

The RRS Sir David Attenborough, named after the British
naturalist, is on a 10-day science trip that's part of a
9-million-pound ($11.3 million) project to investigate how
Antarctic ecosystems and sea ice drive global ocean cycles of
carbon and nutrients.

The British Antarctic Survey said its findings will help improve
understanding of how climate change is affecting the Southern
Ocean and the organisms that live there.

Lift-off for EIRSAT-1, Ireland's first ever satellite

by European Space Agency
December 4, 2023

Six years of hard work and dedication paid off in spectacular
fashion on Dec. 1 as the Educational Irish Research Satellite,
EIRSAT-1, successfully blasted off from Vandenberg Space Force
Base, California. Hitching a ride on a Space-X Falcon-9 launcher,
the tiny satellite—measuring just 10.7cm x 10.7cm x 22.7cm—has
now made history as Ireland's first satellite.

EIRSAT-1 was designed, built, and tested by students from
University College Dublin (UCD) participating in ESA Academy's
Fly Your Satellite! program, a hands-on initiative supporting
university student teams to develop their own satellites
according to professional standards. The launch opportunity
itself was provided by ESA.

ESA experts have been on-hand throughout the satellite's
development to offer training and guidance to dozens of UCD
students. Their learning journey also included test campaigns at
ESA Education's CubeSat Support Facility in Belgium, and
dedicated spacecraft communications sessions both at ESA
Academy's Training and Learning Center and at the European Space
Operations Center in Darmstadt Germany, to learn Ireland's first
spacecraft operations procedures.

"I would like to wholeheartedly congratulate the EIRSAT-1 team
for this successful launch and the start of Ireland's first
exciting adventure in orbit," said Josef Aschbacher, ESA Director
General. I'd also like to thank UCD for joining forces with ESA
towards a common educational objective: boosting the skills of
the young generation," he continued.

"It's only by building capacity that we can make our space
ambitions become a reality, for Ireland and for Europe. With our
Education program we are nurturing generations of citizens who
are learning to use space technology and space solutions in order
to make a difference for our society, our planet and our future."

From low Earth orbit EIRSAT-1 will carry out three main
experiments, which were built from scratch by the students:

GMOD, a detector to study gamma ray bursts, which are the
most luminous explosions in the universe and occur when a
massive star dies or two stars collide.

EMOD, an experiment to see how a thermal treatment protects
the surface of a satellite when in space.

WBC, an experiment to test a new method of using Earth's
magnetic field to change a satellite's orientation in space.

Following EIRSAT-1's deployment to orbit, the student team is now
working to establish contact with the satellite and start
operations from their dedicated ground control facility, also
entirely operated by students and located at UCD in Dublin.

"The team at ESA Education would like to join ESA DG in
expressing their heartfelt congratulations to the EIRSAT-1
students for achieving their incredible goals," said Hugo Marée,
Head of the ESA Education Office.

"Not only has EIRSAT-1 made history by being Ireland's first
satellite, but it has also inspired a generation of Irish school
students to grow their ambitions higher. This has been achieved
thanks to the inspirational activities organized by ESERO Ireland
(a collaboration between ESA and Science Foundation Ireland)
around this mission," he continued. "I am proud of our Education
program which is able to inspire and engage different age groups
towards a future career in STEM."
