To prepare for exploring the Moon during NASA’s Artemis campaign, the agency is conducting a week-long field test in the lunar-like landscape of San Francisco Volcanic Field near Flagstaff, Arizona, to practice moonwalk scenarios.

NASA astronauts Kate Rubins and Andre Douglas are serving as the crewmembers and wearing mockup spacesuit systems as they traverse through the desert, completing a variety of technology demonstrations, hardware checkouts and Artemis science-related operations. 

During the test, two integrated teams will work together as they practice end-to-end lunar operations. The field team consists of astronauts, NASA engineers, and field experts in the Arizona desert conducting the simulated moonwalks, while a team of flight controllers and scientists at NASA’s Johnson Space Center in Houston monitor and guide their activities.

On May 19, 2024, the team successfully tested navigation displays using data from four different data streams: Global Positioning System (GPS)/Inertial Measurement Unit (IMU), camera/IMU, Light Detection and Ranging (LiDAR), and static maps. Technology like this may be used for future Artemis missions to augment mission control communication and help guide crew back to the lunar lander.

“Field tests play a critical role in helping us test all of the systems, hardware, and technology we’ll need to conduct successful lunar operations during Artemis missions,” said Barbara Janoiko, director for the field test at Johnson. “Our engineering and science teams have worked together seamlessly to ensure we are prepared every step of the way for when astronauts step foot on the Moon again.”   

The test consists of four simulated moonwalks that follow operations planned for Artemis III and beyond, as well as six advanced technology runs. During the advanced runs, teams will demonstrate technology that may be used for future Artemis missions, such as display and navigation data stream capabilities in the form of a heads-up display using augmented reality or lighting beacons that could help guide crew back to the lander. 

Ahead of the field test, the science team at Johnson that was competitively selected and tasked with developing the science objectives for the field test, followed a planning process designed for Artemis missions. Their preparation included generating geologic maps, a list of science questions, and prioritized moonwalk locations for both the primary and back-up “landing sites” for the test. 

“During Artemis III, the astronauts will be our science operators on the lunar surface with an entire science team supporting them from here on Earth,” said Cherie Achilles, science officer for the test at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This simulation gives us an opportunity to practice conducting geology from afar in real time.” 

The test will evaluate gaps and challenges associated with lunar South Pole operations, including data collection and communications between the flight control team and science team in Houston for rapid decision-making protocols. 

At the conclusion of each simulated moonwalk, the science team, flight control team, crewmembers, and field experts will come together to discuss and record lessons learned. NASA will take these lessons and apply them to operations for NASA’s Artemis missions, commercial vendor development, and other technology development. 

This field test is the fifth in the series conducted by the Joint Extravehicular Activity and Human Surface Mobility Test Team led out of Johnson. This test expands on previous field tests the team has performed and is the highest fidelity Artemis moonwalk mission simulation to date. 

NASA uses field tests to simulate missions to prepare for deep space destinations. The Arizona desert has been a training ground for lunar exploration since the Apollo era because of the many similarities to the lunar terrain, including craters, faults and volcanic features. 

Through Artemis, NASA will land the first woman, the first person of color, and its first international partner astronaut on the Moon, paving the way for long-term lunar exploration and serving as a steppingstone for astronaut missions to Mars.

Noctilucent Clouds over Poland | Earth Science

Noctilucent Clouds over Poland | Earth Science




Noctilucent clouds (NLCs) are spilling out of the Arctic to lower latitudes. Astrophotographer Marek Nikodem spotted the electric-blue clouds at midnight, June 11-12, 2024, over Szubin, Poland (+53N). 

Nikodem: "These are our first noctilucent clouds of the season here in Poland. It was a very nice display."

NASA scientists study and model the Sun to better understand what it does and why. The Sun has its ups and downs and cycles between them regularly. Roughly every 11 years, at the height of its cycle, the Sun’s magnetic poles flip—on Earth, that would be like if the North and South Poles swapped places every decade—and the Sun transitions from sluggish to active and stormy. At its quietest, the Sun is at solar minimum; during solar maximum, the Sun blazes with bright flares and solar eruptions.

December 2019 marked the beginning of Solar Cycle 25, and the Sun’s activity will once again ramp up until solar maximum, predicted for 2025. This high solar activity is warming Earth's upper atmosphere and breaking apart water molecules required to form noctilucent ices. However, for reasons researchers do not fully understand, Solar Max does not always extinquish the clouds. The appearance of NLCs over Poland suggests that 2024 may be a year when night-shining clouds defy the Sun.

Chinese Scientists Ready to Study Far Side Lunar Samples from Chang'e-6 Probe

Chinese Scientists Ready to Study Far Side Lunar Samples from Chang'e-6 Probe

Chinese scientists are fully prepared to study the lunar samples being brought back to Earth by the Chang'e-6 mission at the country's lunar sample lab at the National Astronomical Observatories (NAO), a Beijing-based agency under the Chinese Academy of Sciences (CAS).

The ascender of the Chang'e-6 probe lifted off from lunar surface on Tuesday June 4, 2024, carrying samples collected from the Moon's far side south polar region for the first time in human history. It has entered a preset orbit around the Moon in preparation for Moon-to-Earth transfer, according to the China National Space Administration (CNSA).

The probe's returner, carrying the samples, is expected to make its planned touchdown in the Siziwang Banner in north China's Inner Mongolia Autonomous Region around June 25, 2024.

The lunar sample lab allows for the long-term storage of the samples in a high purity nitrogen environment and ensures there is no contamination during the research process.

For example, there is a cabinet, or glove box, filled with nitrogen used for sample unsealing at the lab, where lunar samples collected by the previous Chang'e-5 probe in 2020 were unsealed.

"The glove box is filled with nitrogen with pressure inside which is designed to be a little bit higher than the pressure outside the box, so as to prevent air from getting inside to pollute the samples," said Zhou Qin, deputy chief designer of ground application system of Chang'e-6 mission.

Lunar samples to be brought back by the Chang'e-6 mission will also be unsealed at the cabinet and distributed to scientists for research.

According to the lab, lunar samples brought back by the Chang'e-5 mission were categorized and stored based on the standard of "whether they had been exposed to the air."

"The samples, once exposed to the air, can be further divided into two categories. One are the rock samples that we picked out from the lunar soil which are numbered and stored separately. We have already weighed the weight and taken pictures of the rocks by exposing them to the air. The other are the returned samples that we once released to the public. According to the requirements of China's Lunar Exploration and Space Engineering Center, the samples lent out, as long as there is a surplus, must be returned to us. The returned samples can be re-applied and reused by scientists for further research," said Zhou.

The lunar samples which have not been exposed to the air are kept in a nitrogen-filled, sealed glove box.

"The 10 bottles here are used to store original samples collected with a sampling shovel. They are very fine with an average particle size of about 50 microns, which is similar to the thickness of the flour particle size. We divided about 150 grams of samples into each bottle. As we distributed the samples to institutions for research, some bottles are one third or half filled. There are also some borehole samples stored here on the shelve, which have never been exposed to the air," said Zhou.

"At present, the lunar samples we keep at the lab are available for distribution. According to the initial plan, 10 percent of the samples have been kept for remote and permanent backup storage, which means we have made preparations for reserving and sub-sampling," she said.

The CNSA has completed the distribution of six batches of Chang'e-5 lunar samples to domestic research institutions. International scientists and institutions are permitted to apply for the samples in the seventh batch.

Spiral Galaxy NGC 5775: A Galactic Fountain of Youth in Virgo | Hubble

Spiral Galaxy NGC 5775: A Galactic Fountain of Youth in Virgo | Hubble


This NASA/European Space Agency Hubble Space Telescope image shows the edge-on profile of the slender spiral galaxy NGC 5775. Although the spiral is tilted away from us, with only a thin slither on view, such a perspective can be advantageous for astronomers because the regions above and below the galaxy’s disc can be seen much more clearly.

Distance: 85 million light years

For instance, astronomers have previously used the high inclination of this spiral to study the properties of the halo of hot gas that is visible when the galaxy is observed at X-ray wavelengths. The mechanism behind such haloes is unclear, but they are found around spirals that have a high star formation rate, like NGC 5775. A number of astronomers think that hot gas from the disc is driven into the halo by supernova explosions. This  is then returned to the disc as it cools—like a massive galactic fountain.

Meanwhile, there is further disruption taking place in the disc of NGC 5775, as it is in the early stages of a galactic merger. Astronomers have observed bridges of hydrogen gas connecting this edge-on galaxy with a neighboring face-on spiral (NGC 5774). However, neither galaxy yet features a tidal tail—a disrupted stream of gas and stars that extends into space. These are commonplace in strongly interacting pairs, such as the Antennae Galaxies.

NGC 5775 and 5774 are members of the Virgo Cluster and lie at a distance of about 85 million light-years. This color picture was created from images taken using the Wide Field Channel of Hubble’s Advanced Camera for Surveys. Images through a red filter (F625W) were colored blue and images through a filter that isolates the glow from hydrogen gas (F658N) have been colored red. The exposure times were 2292 s and 6848 s, respectively, and the field of view is 3.2 arcminutes across.

The Lion Nebula: Sh2-132 in Cepheus

The Lion Nebula: Sh2-132 in Cepheus

Is the Lion Nebula the real ruler of the constellation Cepheus? This powerful feline appearing nebula is powered by two massive stars, each with a mass over 20 times greater than our Sun. Formed from shells of ionized gas that have expanded, the nebula's energetic matter not only glows, but is dense enough to contract gravitationally and form stars. The angular size of the Lion Nebula, officially named Sh2-132, is slightly greater than that of the full moon. The gaseous iconic region resides about 10,000 light years away in a constellation named after the King of Aethopia in Greek mythology.

Investigating the Habitability of Exoplanets | NASA's Chandra X-ray Observatory

Investigating the Habitability of Exoplanets | NASA's Chandra X-ray Observatory

Using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton, astronomers are testing how habitable exoplanets are based on whether they receive lethal radiation from the stars they orbit. This type of research will help guide observations with the next generation of telescopes aiming to make the first images of planets like Earth.

A team of researchers examined stars that are close enough to Earth that telescopes set to begin operating in the next decade or two could take images of planets in their so-called habitable zones, defined as orbits where the planets could have liquid water on their surfaces.

Any images of planets will be single points of light and will not directly show surface features like clouds, continents and oceans. However, their spectra—the amount of light at different wavelengths—will reveal information about the planet’s surface composition and atmosphere.

There are several other factors influencing what could make a planet suitable for life as we know it. One of those factors is the amount of harmful X-rays and ultraviolet light they receive. These can damage or even strip away a planet’s atmosphere.

A team of astronomers began with a list of stars that are close enough to Earth that future ground and space-based telescopes could make images of planets in their habitable zone. These future telescopes include the Habitable Worlds Observatory and ground-based Extremely Large Telescopes.

Based on X-ray observations of stars using data from Chandra and XMM-Newton, the researchers examined what ones could have hospitable conditions on orbiting planets for life to form and prosper.

The team studied how bright the stars are in X-rays, how energetic the X-rays are, and how much and how quickly they change in X-ray output, for example, due to flares. Brighter and more energetic X-rays can cause more damage to the atmospheres of orbiting planets.

They identified stars where the habitable zone’s X-ray radiation environment is similar to or even milder than the one in which Earth evolved. Such conditions may play a key role in sustaining a rich atmosphere like the one found on Earth.

Observing time on the next generation of telescopes will be precious and extremely difficult to obtain. These X-ray data are helping to refine and prioritize the list of targets and may allow the first image of a planet like the Earth to be obtained more quickly.

Ed Stone: Former JPL Director & Voyager Project Scientist (1936-2024) | NASA

Ed Stone: Former JPL Director & Voyager Project Scientist (1936-2024) | NASA

Ed Stone, former director of the Jet Propulsion Laboratory (JPL) and project scientist for the Voyager mission, died on June 9, 2024. A friend, mentor, and colleague to many, he was known for his straightforward leadership and commitment to communicating with the public. 

Known for his steady leadership, consensus building, and enthusiasm for engaging the public in science, Stone left a deep impact on the space community.

Edward C. Stone was preceded in death by his wife, Alice Stone, whom he met at the University of Chicago. They are survived by their two daughters, Susan and Janet Stone, and two grandsons.

Stone also served as the David Morrisroe professor of physics and vice provost for special projects at Caltech in Pasadena, California, which last year established a new faculty position, the Edward C. Stone Professorship.

Ed Stone, former director of NASA’s Jet Propulsion Laboratory and longtime project scientist of the Voyager mission, passed away on June 9, 2024. He was 88 years old.

“Ed Stone was a trailblazer who dared mighty things in space. He was a dear friend to all who knew him, and a cherished mentor to me personally,” said Nicola Fox, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “Ed took humanity on a planetary tour of our solar system and beyond, sending NASA where no spacecraft had gone before. His legacy has left a tremendous and profound impact on NASA, the scientific community, and the world. My condolences to his family and everyone who loved him. Thank you, Ed, for everything.”

Stone served on nine NASA missions as either principal investigator or a science instrument lead, and on five others as a co-investigator (a key science instrument team member). These roles primarily involved studying energetic ions from the Sun and cosmic rays from the galaxy. He had the distinction of being one of the few scientists involved with both the mission that has come closest to the Sun (NASA’s Parker Solar Probe) and the one that has traveled farthest from it (Voyager).

“Ed will be remembered as an energetic leader and scientist who expanded our knowledge about the universe—from the Sun to the planets to distant stars—and sparked our collective imaginations about the mysteries and wonders of deep space,” said Laurie Leshin, JPL director and Caltech vice president. “Ed’s discoveries have fueled exploration of previously unseen corners of our solar system and will inspire future generations to reach new frontiers. He will be greatly missed and always remembered by the NASA, JPL, and Caltech communities and beyond.”

At the Helm of Voyager

Stone is best known for his work on NASA’s longest-running mission, Voyager, whose twin spacecraft launched in 1977 and are still exploring deep space today. He served as Voyager’s sole project scientist from 1972 until his retirement in 2022. Under Stone’s leadership, the mission took advantage of a celestial alignment that occurs just once every 176 years to visit Jupiter, Saturn, Uranus, and Neptune. During their journeys, the spacecraft revealed the first active volcanoes beyond Earth, on Jupiter’s moon Io, and an atmosphere rich with organic molecules on Saturn’s moon Titan. Voyager 2 remains the only spacecraft to fly by Uranus and Neptune, revealing Uranus’ unusual tipped magnetic poles, and the icy geysers erupting from Neptune’s moon Triton.

Now more than 15 billion miles (24 million kilometers) from Earth, Voyager 1 is the most distant human-made object. Voyager 2, traveling slightly slower and in a different direction, is more than 12 billion miles (20 billion km) from Earth. Both probes are exploring interstellar space—the region outside the heliosphere, which is a protective bubble created by the Sun’s magnetic field and the outward flow of charged particles.

“Becoming Voyager project scientist was the best decision I made in my life,” Stone said in 2018. “It opened a wonderful door of exploration.”

He was particularly proud of the way Voyager quickened the pace of scientific analysis and took advantage of opportunities to engage the public. When Voyager 1 and 2 made their close flybys of the giant planets between 1979 and 1989, Stone was overseeing 11 teams of scientists, all accustomed to releasing their results at a slower pace through peer-reviewed journals.

Stone took the lead in tailoring the peer-review process to the faster pace of the mission’s planetary encounters: In the early afternoon, after data had come down, teams of scientists would decide what they thought their best results were for the day and hold up their conclusions for feedback in front of the whole science steering group.

Based on that discussion, Stone would choose the most interesting results to present to the media and the public the next morning. The scientists would then hone their presentations that evening and even overnight — with Stone often pressing them to come up with analogies that would make the material more approachable for a lay audience—while a graphics team worked on putting together supporting images. After the news conference the following morning, the process would begin anew. This cycle could continue daily through the duration of each planetary encounter.

“It was a very exciting time, and everyone was making discoveries,” said Stamatios “Tom” Krimigis of the Johns Hopkins Applied Physics Laboratory, who has served as the principal investigator of Voyager’s low-energy charged particles instrument since the mission’s launch. “Ed’s approach showed us how much public interest there really was in what Voyager was doing, but it also resulted in better science. You need more than one piece of information to make a picture, and hearing about other scientists’ data helped us interpret our own.”

It was a process that continued to serve the Voyager team well in 2012 and 2013 as they debated whether or not Voyager 1 had exited the heliosphere and entered interstellar space. Some signs pointed to a new environment, but one key marker — the direction of the magnetic field lines around Voyager — hadn’t changed as significantly as scientists expected.

The team remained puzzled for months until Voyager 1’s plasma wave instrument detected a significantly denser plasma environment around the spacecraft — the result of a chance outburst of material from the Sun that set the plasma around Voyager 1 ringing like a bell. Stone gathered the team.

“Nobody could wait to get to interstellar space, but we wanted to get it right,” said Suzanne Dodd, who has served as Voyager project manager, overseeing the engineering team, at JPL since 2010. “We knew there would be people who disagreed. So Ed wanted to understand the full story and the assumptions people were making. He did a good job listening to everybody and letting them participate in the dialogue without anyone monopolizing. Then he made a decision.”

Stone realized that the scientists didn’t need to fixate on the direction of the magnetic field lines. They were a proxy for the plasma environment. The team concluded that the plasma wave science instrument’s detection provided a better analysis of the current plasma environment and was evidence of humankind’s arrival into interstellar space.

Leading JPL

Voyager’s high profile lifted Stone’s profile as well. In 1991, roughly two years after the mission completed its planetary flybys, Stone became director of JPL, serving until 2001. Under his leadership, JPL was responsible for more than two dozen missions and instruments. Highlights for Stone’s tenure included landing NASA’s Pathfinder mission with the first Mars rover, Sojourner, in 1996 and launching the NASA-ESA (European Space Agency) Cassini/Huygens mission in 1997. The first Saturn orbiter, Cassini was a direct outgrowth of the scientific questions that arose from Voyager’s two flybys, and it carried the only probe that has ever landed in the outer solar system (at Titan).

The 1990s were an era of shifting national priorities after the Cold War, with significant cuts in spending in the NASA and defense budgets. Stone restructured several missions so that they could fly under these more stringent cost constraints, including overseeing a redesign of the Spitzer Space Telescope cooling system so that it was more cost effective and could still deliver high-impact science and stunning infrared images of the universe.

Journey to Space

Edward Carroll Stone Jr. was born on Jan. 23, 1936, in Knoxville, Iowa. The eldest of two sons of Edward Carroll Stone Sr. and Ferne Elizabeth Stone, he grew up in the nearby commercial center of Burlington.

Edward Stone Sr. was a construction superintendent who delighted in showing his son how to take things apart and put them back together again — cars, radios, hi-fi stereos. When the younger Stone was in junior high, the principal asked him to learn how to operate the school’s 16 mm movie projector and soon followed up with a request to run the school’s reel-to-reel tape recorder.

“I was always interested in learning about why something is this way and not that way,” Stone said in an interview about this career in 2018. “I wanted to understand and measure and observe.”

His first job was at a J.C. Penney department store, where he worked his way up from stockroom to clerk on the store floor. He also earned money playing French horn in the Burlington Municipal Band.

After high school, Stone enrolled in Burlington Junior College to study physics, and went on to the University of Chicago for graduate school. Shortly after he was accepted, the Soviet Union launched Sputnik and the Space Age began.

“Space was a brand-new field waiting for discovery,” Stone recalled in 2018.

He joined a team at the university that was building science instruments to launch into space. The first he designed rode aboard Discoverer 36, a since-declassified spy satellite that launched in 1961 and took photographs of Earth from space as part of the Corona program. Stone’s instrument, which measured the Sun’s energetic particles, helped scientists figure out why solar radiation was fogging the film and ultimately improved their understanding of the Van Allen belts, energetic particles trapped in Earth’s magnetic field.

In 1964, Stone joined Caltech as a postdoctoral fellow, running the university’s Space Radiation Lab together with Robbie Vogt, who had been a colleague at Chicago. They worked closely on a number of NASA satellite missions, studying galactic cosmic rays and solar energetic particles. In 1972, Vogt recommended Stone to JPL leadership for the position of Voyager project scientist, which he held for 50 years.

Among Stone’s many awards, the National Medal of Science from President George H.W. Bush stands out as the most prominent. In 2019 he won the Shaw Prize in Astronomy, with an award of $1.2 million, for his leadership in the Voyager project, which, as the citation noted, “has over the past four decades, transformed our understanding of the four giant planets and the outer solar system, and has now begun to explore interstellar space.” He was also proud to have a middle school named after him in Burlington, Iowa, as an inspiration to young learners.

A Tribute to Scientist & Explorer Edward C. Stone (1936-2024) | NASA/JPL

Edward C. Stone, former director of NASA’s Jet Propulsion Laboratory (JPL) and longtime project scientist of the Voyager mission, passed away on June 9, 2024. He was 88 years old. In this 2018 video, Stone talks about the Voyager 2 spacecraft reaching interstellar space, six years after Voyager 1 reached the same milestone. The twin Voyager spacecraft were launched in 1977 on a five-year mission that is still operating today. Stone served as the mission’s project scientist for 50 years, from 1972 to 2022.

In addition to his work on Voyager, Stone was the director of JPL from 1991 to 2001. Under his leadership, JPL was responsible for 21 missions and instruments and developed six new missions. Highlights during Stone’s tenure included landing NASA’s Pathfinder mission with the first Mars rover, Sojourner, in 1996 and launching the NASA-European Space Agency (ESA) Cassini/Huygens mission in 1997. The first Saturn orbiter, Cassini was a direct outgrowth of the scientific questions that arose from Voyager’s two flybys, and it carried the only probe that has ever landed in the outer solar system (at Titan).

The twin Voyager 1 and 2 spacecraft are traveling where no spacecraft—or anything touched by humanity—has gone before. As we prepare to celebrate the 47th anniversary of the Voyager 1 launch later this year, we reflect on the vision and work of people like Ed Stone that supported its achievements and enduring legacy.

NASA Analysis Confirms a Year of Monthly Temperature Records | NASA Goddard

NASA Analysis Confirms a Year of Monthly Temperature Records | NASA Goddard


May 2024 was the warmest May on the books, marking a full year of record-high monthly temperatures, NASA scientists found. Average global temperatures for the past 12 months hit record highs for each respective month—an unprecedented streak—according to scientists from NASA’s Goddard Institute for Space Studies (GISS) in New York.

The run of record temperatures fits within a long-term warming trend driven by human activity—primarily greenhouse gas emissions. The trend has become evident over the past four decades, with the last 10 consecutive years being the warmest 10 since record-keeping began in the late 19th century. Before this streak of 12 straight months of record temperatures, the second longest streak lasted for seven months between 2015 and 2016.

“It’s clear we are facing a climate crisis. Communities across America—like Arizona, California, Nevada—and communities across the globe are feeling first-hand extreme heat in unprecedented numbers.

—NASA Administrator Bill Nelson

“We’re experiencing more hot days, more hot months, more hot years,” said Kate Calvin, NASA’s chief scientist and senior climate advisor. “We know that these increases in temperature are driven by our greenhouse gas emissions and are impacting people and ecosystems around the world.”

In NASA’s analysis, a temperature baseline is defined by several decades or more—typically 30 years. The average global temperature over the past 12 months was 2.34 degrees Fahrenheit (1.30 degrees Celsius) above the 20th century baseline (1951 to 1980). This is slightly over the 2.69 degree Fahrenheit (1.5 degree Celsius) level with respect to the late 19th century average.

To calculate Earth’s global temperature, NASA scientists gather data from tens of thousands of meteorological stations on land, plus thousands of instruments on ships and buoys on the ocean surface. This raw data is analyzed using methods that account for the varied spacing of temperature stations around the globe and for urban heating effects that could skew the calculations.

El Niño Subsiding, La Niña Arriving?

Phenomena such as El Niño and La Niña, which alternately warm and cool the tropical Pacific Ocean, can contribute a small amount of variability in global temperatures from year to year. The strong El Niño that began in spring 2023 helped stoke last year’s extreme summer and fall heat.

As of May 2024, scientists at the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center projected a 49% chance of La Niña developing between June and August, and a 69% chance of it developing between July and September. By cooling a large swath of the tropical Pacific, a La Niña event could partially suppress average global temperatures this year.

"It’s hard to know whether 2024 will set another global heat record. Factors like volcanic eruptions and sun-blocking aerosol emissions can affect our climate in any given year. NASA missions are actively studying these influences," said Gavin Schmidt, director of GISS.

“There are open questions that can impact our predictions over the next few years and decades, and we’re in evidence-gathering mode,” Schmidt said. “This year may well end up setting another global temperature record. Right now, it’s in line to be close to 2023.”

Ocean Temperatures and Hurricanes

Scientists are watching to see how ocean temperatures may influence this year’s hurricane season. Temperatures remained high as the 2024 hurricane and typhoon seasons got underway. Across the Northern Hemisphere, ocean temperatures for the January-April period were 2.12 degrees Fahrenheit (1.18 degrees Celsius) above average, according to NOAA. Despite the waning El Niño, temperatures at the sea surface and at deeper depths are still above average in many places, said Josh Willis, an oceanographer at NASA’s Jet Propulsion Laboratory in Southern California.

Willis cited rising carbon dioxide emissions as the main driver of ocean warming. As much as 90% of the excess atmospheric heat in recent decades has been absorbed by the ocean, with much of that heat stored near the water surface.  

“The ocean is the flywheel of our climate,” Willis said. “Since the ocean covers more than two-thirds of Earth, whatever sea surface temperatures are, the rest of the planet follows.”  

La Niña years also can contribute to more active Atlantic hurricane seasons. That’s because La Niña conditions weaken westerly winds high in the atmosphere near the Americas, over the Caribbean Sea and tropical Atlantic Ocean. Wind shear—abrupt changes in wind speed and direction—can cut hurricanes down before they grow. La Niña effectively lifts this brake, allowing tropical storms to form and intensify unimpeded.

NASA’s full dataset of global surface temperatures, as well as details of how NASA scientists conducted the analysis, are publicly available from GISS, a NASA laboratory managed by the agency’s Goddard Space Flight Center in Greenbelt, Maryland.

Image Description:

Line graph of monthly temperature anomalies for each month of every year from 1880 to May 2024. The X-axis runs from June to May and the Y-axis is anomalies in degrees Celsius from -.5 to 1.5. Each month’s anomaly forms a point on a line for that entire year. As the points appear, the current year’s line is red and fades to yellow then white as newer years are added. Overall, the earlier years in the timespan are much cooler, sometimes dipping even below the -.5 degree Y-axis line. Over time, temperature anomalies increase, as human activities warm the climate, with small variations between individual years. The final 12-month span that runs from June 2023 to May 2024 is a red line running above each of its respective months, representing a full year of record high monthly temperatures. Finally, the graph turns 90 degrees toward the viewer, creating a familiar, annual temperature anomaly line graph. The X-axis changes to years, running from 1880 to 2024, showing overall warming.
