TEXT I
The world's strongest ocean current should be getting
faster - instead, it is at risk of failing.
Antarctica's remote and mysterious current has a profounp
influence on the climate, food systems and Antarctic
ecosystems. Can we stop it weakening by 2050? The
Antarctic Circumpolar Current is the strongest ocean
current on the planet. It's five times stronger than the Gulf
Stream and more than 100 times stronger than the
Amazon River. It forms part of the global ocean "conveyor
belt" connecting the Pacific, Atlantic and Indian oceans.
The system regulates Earth's climate and pumps water,
heat and nutrients around the globe. But fresh, cool water
from melting Antarctic ice is diluting the salty water of the
ocean, potentially disrupting the vital ocean current.
The Antarctic Circumpolar Current is like a moat around
the icy continent. The current helps to keep warm water at
bay, protecting vulnerable ice sheets. It also acts as a
barrier to invasive species such as southern bull kelp and
any animals hitching a ride on these rafts, spreading them
out as they drift towards the continent. It also plays a big
part in regulating the Earth's climate.
The influence of climate change:
Ocean currents respond to changes in temperature, salt
levels, wind patterns and sea ice extent. So the global
ocean conveyor belt is vulnerable to climate change on
multiple fronts. Previous research suggested one vital part
of this conveyor belt could be headed for a catastrophic
collapse. Theoretically, warming water around Antarctica
should speed up the current. This is because density
changes and winds around Antarctica dictate the strength
of the current. Warm water is less dense (or heavy) and
this should be enough to speed up the current.
Far-reaching consequences:
The consequences of a weaker Antarctic Circumpolar
Current are profound and far-reaching. As the main current
that circulates nutrient-rich waters around Antarctica, it
plays a crucial role in the Antarctic ecosystem. Weakening
of the current could reduce biodiversity and decrease the
productivity of fisheries that many coastal communities rely
on. It could also aid the entry of invasive species such as
southern bull kelp to Antarctica, disrupting local
ecosystems and food webs.

TITLE: Asteroid probe snaps rare images of Martian Moon
March 13, 2025 3:29 PM
By Agence France-Press
Paris -
On the way to investigate the scene of a historic asteroid
collision, a European spacecraft swung by Mars and
captured rare images of the red planet's mysterious small
moon Deimos, the European Space Agency said
Thursday.
Europe's HERA mission is aiming to find out how much of
an impact a NASA spacecraft made when it deliberately
smashed into an asteroid in 2022 in the first test of our
planetary defenses.
But HERA will not reach the asteroid - which is 11 million
kilometers from Earth in the asteroid belt between Mars
and Jupiter - until late 2026.
On the long voyage there, the spacecraft swung around
Mars on Wednesday.
The spacecraft used the planet's gravity to get a "kick" that
also changed its direction and saved fuel, mission analyst
Pablo Munoz told a press conference.
For an hour, HERA flew as close as 5,600 kilometers from
the Martian surface, at a speed of 33,480 kilometers an
hour.
It used the opportunity to test some of its scientific
instruments, snapping around 600 pictures, including rare
ones of Deimos.
The lumpy, 12.5-kilometer-wide moon is the smaller and
less well-known of the two moons of Mars.
Exactly how Deimos and the bigger Phobos were formed
remains a matter of debate.
Some scientists believe they were once asteroids that
were captured in the gravity of Mars, while others think they could have been shot from a massive impact on the
surface.
The new images add "another piece of the puzzle" to
efforts to determine their origin, Marcel Popescu of the
Astronomical Institute of the Romanian Academy said.
There are hopes that data from HERA's "HyperScout" and
thermal infrared imagers which observe colors beyond
the limits of the human eye - will shed light on this mystery
by discovering more about the moon's composition.
Those infrared imagers are why the red planet appears
blue in some of the photos.
Next, HERA will turn its focus back to asteroid Dimorphos.
When NASA's DART mission smashed into Dimorphos in
2022, it shortened the 160-meter-wide asteroid's orbit
around its big brother Didymos by 33 minutes.
Although Dimorphos itself posed no threat to Earth, HERA
intends to discover whether this technique could be an
effective way for Earth to defend itself against possibly
existence-threatening asteroids in the future.
Space agencies have been working to ramp up Earth's
planetary defences, monitoring for potential threats so they
can be dealt with as soon as possible.
Earlier this year, a newly discovered asteroid capable of
destroying a city was briefly given a more than 3% chance
of hitting Earth in 2032.
However further observations sent the chances of a direct
hit back down to nearly zero.
Richard Moissl, head of the ESA's planetary defense
office, said that asteroid, 2024 YR, followed a pattern that
will become more common.
As we get better at scanning the skies, "we will discover
asteroids at a higher rate," he said.
The ESA is developing a secondary planetary defense
mission to observe the 350-meter-wide asteroid Apophis,
which will fly just 32,000 kilometers from Earth on April 13,
2029.
If approved by the ESA's ministerial council, the Ramses
mission will launch in 2028, reaching the asteroid two
months before it approaches Earth.

TITLE: Asteroid probe snaps rare images of Martian Moon
March 13, 2025 3:29 PM
By Agence France-Press
Paris -
On the way to investigate the scene of a historic asteroid
collision, a European spacecraft swung by Mars and
captured rare images of the red planet's mysterious small
moon Deimos, the European Space Agency said
Thursday.
Europe's HERA mission is aiming to find out how much of
an impact a NASA spacecraft made when it deliberately
smashed into an asteroid in 2022 in the first test of our
planetary defenses.
But HERA will not reach the asteroid - which is 11 million
kilometers from Earth in the asteroid belt between Mars
and Jupiter - until late 2026.
On the long voyage there, the spacecraft swung around
Mars on Wednesday.
The spacecraft used the planet's gravity to get a "kick" that
also changed its direction and saved fuel, mission analyst
Pablo Munoz told a press conference.
For an hour, HERA flew as close as 5,600 kilometers from
the Martian surface, at a speed of 33,480 kilometers an
hour.
It used the opportunity to test some of its scientific
instruments, snapping around 600 pictures, including rare
ones of Deimos.
The lumpy, 12.5-kilometer-wide moon is the smaller and
less well-known of the two moons of Mars.
Exactly how Deimos and the bigger Phobos were formed
remains a matter of debate.
Some scientists believe they were once asteroids that
were captured in the gravity of Mars, while others think they could have been shot from a massive impact on the
surface.
The new images add "another piece of the puzzle" to
efforts to determine their origin, Marcel Popescu of the
Astronomical Institute of the Romanian Academy said.
There are hopes that data from HERA's "HyperScout" and
thermal infrared imagers which observe colors beyond
the limits of the human eye - will shed light on this mystery
by discovering more about the moon's composition.
Those infrared imagers are why the red planet appears
blue in some of the photos.
Next, HERA will turn its focus back to asteroid Dimorphos.
When NASA's DART mission smashed into Dimorphos in
2022, it shortened the 160-meter-wide asteroid's orbit
around its big brother Didymos by 33 minutes.
Although Dimorphos itself posed no threat to Earth, HERA
intends to discover whether this technique could be an
effective way for Earth to defend itself against possibly
existence-threatening asteroids in the future.
Space agencies have been working to ramp up Earth's
planetary defences, monitoring for potential threats so they
can be dealt with as soon as possible.
Earlier this year, a newly discovered asteroid capable of
destroying a city was briefly given a more than 3% chance
of hitting Earth in 2032.
However further observations sent the chances of a direct
hit back down to nearly zero.
Richard Moissl, head of the ESA's planetary defense
office, said that asteroid, 2024 YR, followed a pattern that
will become more common.
As we get better at scanning the skies, "we will discover
asteroids at a higher rate," he said.
The ESA is developing a secondary planetary defense
mission to observe the 350-meter-wide asteroid Apophis,
which will fly just 32,000 kilometers from Earth on April 13,
2029.
If approved by the ESA's ministerial council, the Ramses
mission will launch in 2028, reaching the asteroid two
months before it approaches Earth.
