NASA Launches Small Climate Satellite to Study Earth’s Poles




NASA has successfully launched the first of two CubeSats as part of the PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission. This mission aims to enhance our understanding of how Earth’s polar regions affect the planet's energy balance. The CubeSat was launched from Rocket Lab’s Launch Complex 1 in Māhia, New Zealand, and its primary goal is to measure the far-infrared radiation emitted from the Arctic and Antarctic.

The Importance of Polar Measurements

The PREFIRE mission addresses a significant gap in climate science. The balance between the incoming heat from the Sun and the outgoing heat from Earth, known as Earth’s energy budget, is crucial in determining the planet's temperature and climate. A substantial portion of the heat radiated from the polar regions is emitted as far-infrared radiation, but detailed measurements of this type of energy have been lacking.

How PREFIRE Works

The PREFIRE CubeSats are equipped with thermal infrared spectrometers, which use specialized mirrors and sensors to measure infrared wavelengths. Despite their small size, these instruments are powerful enough to gather critical data that will help scientists understand the dynamics of Earth’s heat balance. This data will be vital in improving predictions of how ice, seas, and weather patterns will change in response to global warming.

Collaborative Effort

The PREFIRE mission is a collaborative project involving multiple institutions. NASA’s Jet Propulsion Laboratory (JPL) manages the mission, and the University of Wisconsin-Madison processes the data collected by the instruments. Blue Canyon Technologies built the CubeSats, and Rocket Lab USA Inc. provided the launch services.

Future Implications

By providing new measurements of far-infrared radiation, PREFIRE will enable researchers to refine climate models, which are essential for predicting future environmental changes. This information will help various stakeholders, including farmers, fishing fleets, and coastal communities, to build resilience against the impacts of climate change.

Conclusion

NASA’s PREFIRE mission represents a significant step forward in climate research. By focusing on the polar regions, these CubeSats will provide valuable data that can enhance our understanding of Earth's energy budget and improve our ability to predict and mitigate the effects of climate change.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

  Non-contact exposure to dinotefuran disrupts honey bee homing by altering  MagR  and  Cry2  gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering  MagR  expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the  MagR  gene responded to magnetic fields only in the presence of light, with  Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

  “Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups.  Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Start the New Year Humming Like a Bee

  Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The largest “killer hornets” in the world were exterminated in the US

  The largest “killer hornets” in the world were exterminated in the US The US informed that it had exterminated the worldʼs largest hornets, nicknamed "killer hornets" — they are capable of occupying a hive of honey bees in just 90 minutes, decapitating all its inhabitants and feeding their offspring to their own. This  was reported  by the Department of Agriculture in Washington. The hornets, which can reach five centimeters in length, were previously called Asian giant hornets, but in 2019 they were also spotted in Washington state near the Canadian border. In China, these insects killed 42 people and seriously injured 1,675. A dead northern giant hornet (below) next to a native bald hornet. According to experts, the hornets could have entered North America in plant pots or shipping containers. The hornet can sting through most beekeeper suits because it produces nearly seven times more venom than a honeybee and stings multiple times. Thatʼs why the Washington Departme...
