A private U.S. spacecraft bound for the moon has captured
stunning images of Earth one week into its flight.
Still circling Earth, Firefly Aerospace's lunar lander fired its
thrusters Thursday to put it on a path to reach the moon in over
a month. Dubbed Blue Ghost, the spacecraft beamed back photos and
video of the Blue Marble, our planet. The Texas company released
the images Friday.
It carries experiments for NASA, part of the space agency's
effort to return astronauts to the moon this decade.
Blue Ghost is one of two lunar landers launched from Florida by
SpaceX on Jan. 15. It's targeting a moon touchdown on March 2.
The other lander is sponsored by the Japanese company ispace and
taking an even longer route, with a landing in late May or early
June.
It's the first moonshot for Firefly and the second for ispace,
which crashed its first lander into the moon in 2023. Tokyo-based
ispace's latest lander, Resilience, is still orbiting Earth and
performing all its maneuvers to close in on the moon.

Space researchers build traffic light system to warn of dangerous
solar storms
by Jonathan O'Callaghan
January 24, 2025
Researchers have created an improved traffic light system for
predicting geomagnetic storms. They are now testing how well
these algorithms can prepare us for incoming space storms that
can wreak havoc by knocking out satellites in space and power
grids on Earth.
Yuri Shprits, a space scientist at the German Research Center for
Geosciences in Potsdam, is on a mission to save our planet.
We have known for a long time that much of our modern way of life
is threatened by the whims of the sun. If our star suddenly
enters a more active period, it can cause geomagnetic storms that
knock out satellites or cause blackouts on Earth.
But can we predict when these storms will arrive, how they will
affect the Earth's environment and infrastructure and ensure we
are prepared? This is what Shprits has been working on, starting
with an EU project named PAGER that ran from 2020 until 2023.
Predicting space weather
The researchers' goal was to develop an algorithm that could pull
data from sun-observing telescopes and satellites together with
data from Earth-orbiting satellites. Based on that, they could
predict when a dangerous geomagnetic storm is heading in our
direction and what the consequences would be for the
infrastructure in space and on the ground.
To that end, the researchers connected different computer models
of the solar environment and near-Earth space.
In a best-case scenario, said Shprits, it could "take us an hour
or two to calculate what would arrive to Earth and what effects
it would have in the near-Earth environment, but it would
actually take two days for this disturbance to arrive."
As it can take another couple of days for the radiation that can
be harmful to satellites to build up, this could allow some time
to prepare.
The algorithm devised by the PAGER team is now being put through
its paces to see how useful it can be.
"After decades of fundamental space research, that started with
the first US satellite discovering harmful space radiation in
1958, we are finally at a point where we have reached predictive
capabilities," said Shprits. "We're very excited."
Storm front
A geomagnetic storm occurs when a powerful eruption from the sun
interacts with our planet's magnetic field.
As solar wind travels from the sun to Earth, it can carry charged
particles that interact with Earth's protective magnetic field.
These get further heated inside the magnetosphere, creating
highly energized particles that can be harmful to satellites.
The collision of these particles with particles in Earth's
atmosphere can produce the magnificent aurorae seen from Earth.
But they also pose a danger as they can interfere with
satellites' electronic systems. Such geomagnetic storms have hit
our space installations quite recently.
In February 2022, the US company SpaceX lost 38 of its Starlink
internet satellites when a powerful geomagnetic storm pulled them
back into Earth's atmosphere after they had launched.
The US firm Intelsat, meanwhile, lost control of its galaxy 15
satellite in April 2010 because of a geomagnetic storm. "It
started drifting, threatening other spacecraft, due to frequency
interference," said Shprits. "This could be very costly because
the price of a spacecraft can be over a billion euros."
Geomagnetic storms also cause problems on Earth. The electric
currents they create can overload power plants and cause
temporary blackouts. This occurred in Quebec, Canada, in 1989,
when a geomagnetic storm caused a widespread nine-hour blackout.
Very strong storms in October and November 2003 caused a
disruption of satellite services, anomalies on numerous
satellites, and disruption of communication, power grids, and GPS
navigation in many regions around the globe.

Radiation belts
Most near-Earth satellites also operate in Earth's radiation
belts, a region of space up to almost 58,000 kilometers above our
planet where many charged particles become trapped by Earth's
magnetic field. These belts can dramatically intensify during
storms.
"GPS satellites operate in the heart of these belts where the
radiation is the most damaging," said Shprits. Even though these
spacecraft are well protected, the most energetic particles can
penetrate their shielding and still damage them.
To protect against solar events, countries in Europe and the US
have space weather prediction centers that can forecast when bad
storms will arrive on Earth. However, until recently, these
predictions were not connected to models able to predict
radiation in space, how this radiation would penetrate spacecraft
or the potential effects on Earth.
In the PAGER project, scientists from Europe and the US combined
the models from the sun and solar environment with those for the
Earth environment to develop a comprehensive predictive system.
Shprits pointed out that "some of the space weather predictions
are really complex and convoluted and stakeholders sometimes do
not have Ph.D.s in space physics. They just want to know if it's
going to be safe or not."
Space traffic light
The PAGER team's goal was therefore to create a simple traffic
light system based on predictions. It tells a satellite operator
if conditions in space are likely to be safe or not.
Using PAGER, an operator will immediately know if the situation
is red and they should consider temporarily switching satellites
into protective mode or if power grid operators need to take
preventive measures. Yellow means they need to be wary of
potential effects, while green signals that everything is fine.
"Green means 'don't worry, nothing is happening,'" said Shprits.
"Sometimes that's actually the most useful for them because with
storms, they want a clear sign they can go back to normal
operations."
To make these calculations, PAGER is constantly running on
powerful machines at a computer center at the German Research
Center for Geosciences.
"Usually the most difficult predictions are done in the middle of
the night so that it doesn't overload the computers," said
Shprits.
He said his team has moved to predicting probabilities,
explaining that it is virtually impossible to make very precise
long-term predictions of the effects of the storm.
"If we say that with a certainty of 80%, there will be very harsh
conditions in space, it's the same as for terrestrial weather,
when we are told there is an 80% chance of rain."
"That gives us an idea that it's better to take an umbrella. It's
the same with satellites."
Refining models
Shprits is currently in discussions with the European Space
Agency (ESA) for a new project that would allow ESA to adopt some
of the PAGER models in its operation.
The goal is to continue improving the prediction services and
make the analysis of incoming space weather events better and
better.
"We're trying to use machine learning in many places and blend it
into this infrastructure. We are also trying to use all the
available real-time data and blend it with our predictions so
that the measurements can refine our models."
Another thing that could help is more satellite data. Shprits
explained that an upcoming ESA project to monitor the near-Earth
radiation environment will provide "real-time measurements of the
harsh radiation in the magnetosphere that would be really useful
for us." It will do so by flying through the radiation belts and
taking measurements.
"There are also proposals to put radiation detectors on all
commercial spacecraft," he said. "That would certainly help us
get a much better and bigger picture of what's going on in space.
We have now developed tools to use all this data and improve our
predictions."
