Arctic Winter Sea Ice Ties Record Low, NASA, NSIDC Scientists Find
2026-03-26 17:00
For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square miles (14.29 million square kilometers), very close to the 2025 peak of 5.53 million square miles (14.31 million square kilometers). Scientists with NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder, note that the two years are statistically tied.
Along with the overall extent, researchers are also observing changes in ice thickness. “Based on what we’re seeing with NASA’s ICESat-2 satellite, much of the ice in the Arctic is thinner this year, especially in the Barents Sea northeast of Greenland.,” said Nathan Kurtz, chief of the Cryospheric Sciences Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The Sea of Okhotsk that borders northern Japan and Russia also had relatively low ice this year — a region that naturally experiences significant year-to-year variability.”
Scientists with NASA and NSIDC found that this winter’s peak Arctic ice coverage continues the long-term trend observed over the past several decades. This year, peak ice cover was below the average levels between 1981 and 2010 by roughly half a million square miles (about 1.3 million square kilometers).
Sea ice extent is defined as the total area of the ocean with at least 15% ice concentration. The area of the Arctic Ocean covered in ice expands in the cold of winter. Although much of the sea ice melts in warmer months, some ice remains throughout the year. Recently, less new ice has been forming. As a result, less multi-year ice has accumulated.
“A low year or two don’t necessarily mean much by themselves,” said NSIDC ice scientist Walt Meier. But viewed within the long‑term downward trend since 1979, Meier added, they add to the overall picture of change in Arctic sea ice throughout the seasons.
In the Antarctic, summer sea ice reached an annual low of 996,000 square miles (2.58 million square kilometers) on Feb. 26. This year’s coverage represents an increase compared to the unusually low levels of the past four years. Although 100,000 square miles (260,000 square kilometers) lower than the 1981–2010 average, the Antarctic sea ice minimum was well above the record low set on Feb. 21, 2023, of 691,000 square miles (1.79 million square kilometers).
Scientists at NSIDC previously tracked sea ice extent primarily using satellites in the Defense Meteorological Satellite Program. In recent years, the NSIDC has relied on JAXA’s (Japan Aerospace Exploration Agency) Advanced Microwave Scanning Radiometer 2 for real-time sea ice data. Researchers also compare ice coverage to historical sources, such as the data collected between 1978 and 1985 with the Nimbus-7 satellite that was jointly operated by NASA and the National Oceanic and Atmospheric Administration.

Curiosity Blog, Sols 4838-4844: Wrapping Up the Boxwork Terrain
Written by Deborah Padgett, MSL Operations Product Ground System Task Lead at NASA’s Jet Propulsion Laboratory
Earth planning date: Friday, March 20, 2026
Curiosity has just concluded a very intense week of science observations and engineering activities, as it wraps up its monthslong investigation of the Martian boxwork terrain. Three days of planning this week by the MSL science and engineering team has led to three rover drives, three sets of targets for detailed study by instruments on Curiosity’s arm, and a vast array of in-situ data characterizing the southern reaches of the boxwork terrain on the shoulder of Mount Sharp on Mars.
As the week began on Mars sol 4838, Curiosity used cameras on Mastcam and ChemCam to image ridge and butte targets “Salar de Maricunga,” “El Misti,” “Saipina” ridges and the “Paniri” butte. Mastcam also looked at bedrock fractures on target “Sajta.” The laser spectrometer on ChemCam examined the composition of the target “Tacitas.” After brushing away a great deal of dust off the bedrock target “Toro Wharku” with the DRT, then MAHLI and APXS studied it in detail. MAHLI also performed detailed imaging of the nearby ledge “Rincodillas.” In the afternoon, Mastcam Tau and Navcam line-of sight observations measured the amount of dust in the Martian atmosphere.
On sol 4839 Curiosity finished up investigation of Toro Wharku with ChemCam laser spectroscopy and Mastcam imaging. A long-distance ChemCam RMI 10×1 mosaic was obtained on the Paniri butte, and Navcam took cloud and dust-devil movies. The rover then drove 35 meters (about 115 feet) toward the southern contact of the boxwork terrain with the adjacent sulfate unit, and performed post-drive photography of a 360-degree panorama around the vehicle using Navcam.
On Sol 4840, those images allowed selection of a uniquely shaped rock formation dubbed “Llisa” for laser spectrometer study with ChemCam and Mastcam. Although no reachable bedrock was smooth enough for DRT brushing, MAHLI obtained microscopic images of “Chusumayo” and APXS target “Sierra Gorda,” in bedrock showing very intriguing sedimentary layers. Mastcam also imaged these layers at targets “Limbaba” and “Limbaba2.” The ChemCam telescope RMI camera looked back along Curiosity’s path at the now distant Mishe Mokwa butte, viewing its stratigraphy from a different angle. Atmospheric studies included a Mastcam sky survey, Mastcam tau, and Navcam dust-devil movie. The following sol, 4841, concluded the study of Chusumayo with ChemCam LIBS observations of nearby target “La Troya.”
On Sol 4841, Curiosity drove 39 meters (about 128 feet) farther south. In Friday’s plan for sols 4842 through 4844, the sol starts with ChemCam laser spectrometer composition and Mastcam imaging studies of outcrop “San Julien,” followed by telescopic RMI images of the “Santa Rita” dark ridge material. Mastcam will then obtain a series of mosaics documenting the southern contact between the boxwork structures and the sulfate unit, from nearby bedrock to the more distant hillsides of the Paniri butte. Mastcam imaging will also investigate the possibility of regolith movement in a trough. A supra horizon cloud movie, dust-devil movie, and line-of-sight dust observations with Navcam will integrate atmospheric investigations into the morning science block. Curiosity will then unstow the arm, performing a DRT brushing, MAHLI imaging, and APXS measurement on target “Challapata.” Another Navcam line-of-sight plus a Mastcam tau will complete atmospheric dust measurements for the sol.
The following sol, 4843, will see ChemCam laser spectroscopy and Mastcam imaging of dark ridge target “Santa Laura.” Mastcam will then obtain additional mosaics of the southern contact (“Yungas de Arepucho”), as well as a “Limbaba lookback” target. ChemCam’s RMI telescope will image the upper reaches of Paniri butte, complementing the Mastcam coverage. Morning and evening studies by Navcam and Mastcam will continue the time series of dust and dynamics in the Martian atmosphere, accompanied by an overnight APXS atmospheric observation.
On the morning of sol 4844, ChemCam will complete the study of Challapata with laser spectroscopy, and Mastcam will document the changes in the target after it is zapped. After a ChemCam passive sky observation and Navcam dust-devil survey, Curiosity will drive 11 more meters to the south (36 feet), most likely crossing the long-awaited boundary between the Martian boxwork structures and the sulfate unit beyond. During the drive, MAHLI will perform a full set of wheel imaging to track the wear on the rover’s wheels. In concert with the post-drive imaging, ChemCam and Navcam will perform an AEGIS investigation, allowing the on-board processing of Navcam data to choose a ChemCam LIBS target before our human team sees the images. The plan concludes on the morning of sol 4845 with ChemCam laser spectroscopy of this new AEGIS target, in addition to atmospheric studies with Navcam and Mastcam.
Next week, Curiosity leaves the Martian boxwork terrain behind in its quest for new discoveries.

NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet
2026-03-26 14:00
NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet
Illustration: NASA, ESA, CSA, Ralf Crawford (STScI)
Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence of a comet reversing its spin.
The object, comet 41P/Tuttle-Giacobini-Kresák, or 41P for short, likely originated in the Kuiper Belt, and was flung into its current trajectory by Jupiter’s gravity, now visiting the inner solar system every 5.4 years.
After its 2017 close passage around the Sun, scientists found that comet 41P experienced a dramatic slowdown in its rotation. Data from NASA’s Neil Gehrels Swift Observatory in May 2017 showed the object was spinning three times more slowly than it had in March 2017 when it was observed by the Discovery Channel Telescope at Lowell Observatory in Arizona.
A new analysis of follow-up Hubble observations has shown the spin of this comet took an even more unusual turn.
Hubble images from December 2017 detected the comet spinning much faster again, with a period of approximately 14 hours, compared to the 46 to 60 hours measured by Swift. The simplest explanation, researchers say, is that the comet continued slowing until it almost stopped, and was then forced to spin in the near-opposite direction by outgassing jets on its surface.
The science paper detailing this finding published Thursday in The Astronomical Journal.
Small, temperamental nucleus
Hubble also constrains the size of the comet’s nucleus, measuring it at around 0.6 miles across (about a kilometer), or about three times the height of the Eiffel Tower.
This is especially small for a comet, making it easy to torque, or twist.
As a comet approaches the Sun, heat causes frozen ices to sublimate, venting material into space.
“Jets of gas streaming off the surface can act like small thrusters,” said paper author David Jewitt of the University of California at Los Angeles. “If those jets are unevenly distributed, they can dramatically change how a comet, especially a small one, rotates.”
The comet was originally spinning in one direction, but gas jets pushing against that motion gradually slowed it down. Because the jets kept pushing, they ultimately caused the comet to start rotating in the opposite direction.
“It’s like pushing a merry-go-round,” said Jewitt. “If it’s turning in one direction, and then you push against that, you can slow it and reverse it.”
Evidence of rapid evolution
The study also shows that the comet’s overall activity has declined significantly since earlier returns. During its 2001 perihelion passage, 41P was unusually active for its size. By 2017, its gas production had decreased by roughly an order of magnitude.
This change suggests that the comet’s surface may be evolving quickly, possibly as near-surface volatile materials become depleted or covered by insulating dust layers.
Most changes in comet structure occur over centuries or longer. The rapid rotational shifts observed in comet 41P provide a rare opportunity to witness evolutionary processes unfolding on a human timescale.
Modeling based on the measured torques and mass loss rates suggest that continued rotational changes could eventually lead to structural instability for comet 41P. If a comet spins too rapidly, centrifugal forces can overcome its weak gravity and strength, potentially causing fragmentation or even disintegration.
“I expect this nucleus will very quickly self-destruct,” said Jewitt.
Yet, comet 41P has likely occupied its present orbit for roughly 1,500 years.
Archival find
Hubble has been collecting imaging and spectroscopic data from across the cosmos for over 35 years, and all of those observations are available in the Mikulski Archive for Space Telescopes, a central repository for data from more than a dozen astronomical missions, including Hubble.
Jewitt found these observations while browsing the archive, and realized they were yet-to-be analyzed.
By making NASA’s science data open to all, observations made years, or even decades ago, can be revisited to answer new scientific questions. In many cases, scientists continue to make discoveries not just with new observations, but by mining the archive built over decades of space exploration.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.
