A Grand, Snow-Rimmed Canyon

A portion of the Grand Canyon, photographed from above, forms a U shape. The plateau on both sides of the canyon is partially covered in a layer of white snow.
January 26, 2026

A sunny day in early 2026 revealed the remnants of a winter storm on Arizona’s high desert—and produced a striking, if somewhat puzzling, display of light and shadow in the Grand Canyon. An astronaut aboard the International Space Station captured these photographs of the distinct topography on January 26, 2026.

Snow flurries were flying in the area the previous two days, as they were across much of the central and eastern U.S. Hazardous conditions within Grand Canyon National Park prompted officials to close Desert View Drive, which runs along a portion of the South Rim shown in the photo above, and to issue warnings about icy trails. (The North Rim is closed to traffic in winter and early spring.) When the road reopened around the time of these photos, a layer of white remained on both the South Rim, at an elevation of around 7,000 feet (2,100 meters), and the North Rim, at about 8,000 feet (2,400 meters).

A portion of the Grand Canyon, with the curving Colorado River at its bottom, runs across the width of this downward-looking photo. Snow covers some of the plateau on both sides of the canyon, with more appearing on the North Rim.

Snow is typical at these high elevations in winter. The South Rim and North Rim see average season totals of 58 inches and 142 inches, respectively. At lower, warmer elevations, precipitation tends to fall as rain. On January 24, for example, snow fell on the plateau, while a weather station at Phantom Ranch on the canyon floor recorded 0.06 inches of rain.

If these photos make the iconic feature of the American West look more like a mountain range than a vast chasm, the effect is likely due to a visual illusion called relief inversion. Many people have an unconscious expectation that a light source should come from the top of an image. In these images, however, the Sun is shining from the south, or the bottom of the photos. Though the shadows on the canyon walls may be visually deceiving, the presence of snow helps to signal that the flat areas sit at higher elevations.

Astronaut photographs ISS074-E-208838 and ISS074-E-208848 were acquired on January 26, 2026, with a Nikon Z9 digital camera using a focal length of 400 millimeters. They are provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The images were taken by a member of the Expedition 74 crew. The images have been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Lindsey Doermann.

Boreal Forests Are Shifting North

For the first time, researchers have been able to confirm that our planet’s boreal forests are on the move.
NASA’s Goddard Space Flight Center/Chris Burns

The boreal forest—the world’s largest terrestrial biome—is warming faster than any other forest type. To understand the changing dynamics of boreal forests, Feng et al., 2026 analyzed the biome from 1985 to 2020, leveraging the longest and highest-resolution satellite record of calibrated tree cover to date. The study, published in February in Biogeosciences with four co-authors from NASA Goddard Space Flight Center, confirms a northward shift in boreal forest cover over the past four decades. Landsat imagery played a central role in this study: the researchers applied machine learning to process 224,026 scenes collected by Landsats 4, 5, 7, and 8 to create annual, 30-meter resolution maps of tree cover across the entire boreal biome. They downscaled and extended calibrated MODIS Vegetation Continuous Fields data to 30-meter resolution, creating a 36-year time series (1984-2020) that provided unprecedented spatial detail for tracking forest changes.

The analysis revealed that boreal forests both grew in size and moved northward. The forests expanded by 0.844 million km² (a 12% increase) and shifted northward by 0.29° mean latitude, with gains concentrated between 64-68°N. Their work also showcased the capacity of new growth to act as a carbon sink. Young boreal forests (up to 36 years) hold an estimated 1.1-5.9 petagrams of carbon (Pg C) with potential to sequester an additional 2.3-3.8 Pg C if allowed to mature. Landsat’s long time series of highly calibrated data allows researchers to study how ecosystems shift over decades, a crucial insight into our changing world.

A Winter Blanket Covers North Carolina

A satellite image centered on North Carolina shows white snow covering most of the state, with additional snowy patches in neighboring states. Some forested and urban areas appear gray. To the right, a strip of barrier islands appears white against the green and blue Atlantic Ocean.
February 2, 2026

A potent winter storm in late January 2026 left much of North Carolina dealing with significant snow accumulations. Though the state is no stranger to snow, such widespread coverage is unusual.

This image, acquired on February 2 with the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Terra satellite, reveals a nearly continuous blanket of white stretching from mountain cities in the west to beachfront towns in the east. According to the North Carolina State Climate Office, measurable snow fell in all 100 counties for the first time in more than a decade.

Snowfall in North Carolina typically requires cold air funneled in from the north to combine with moisture supplied by a low-pressure system. During the January 31 weekend event, Arctic air from earlier in the week lingered across the state as a storm approached along a near-shore track, setting the stage for widespread snow.

Snow totals exceeded a foot in some of the state’s western, mountainous regions, following several years without significant snowfall events, though some locations such as Asheville saw smaller amounts. The storm even pushed south into Greenville, South Carolina, in the foothills of the Blue Ridge Mountains, where the downtown area saw about 5 inches (13 centimeters) by the evening of January 31, according to the National Weather Service.

In the Piedmont region, the hilly central part of the state, Charlotte received nearly a foot of snow—the most since 2004—while Raleigh saw a lighter accumulation of 2.8 inches, according to the state climate center.

A detailed satellite image centered on eastern North Carolina shows white snow covering coastal areas along the blue-green Atlantic Ocean. Gray ice is visible on some rivers and lakes.
February 2, 2026

Even coastal parts of the state traded brown sandy beaches for a blanket of white, with more than a foot reported in parts of Carteret County. Beaufort, a mainland town in the southern Outer Banks area, experienced heavy blowing snow. Slightly inland, Greenville received 14 inches, an amount not seen since a large storm in March 1980.

Though appearing serene from space, the storm posed real hazards on the ground. Dangerous road conditions snarled traffic and caused collisions, according to local news reports, while coastal areas saw high winds and waves. Overwash on Highway 12 in the Outer Banks coated parts of the road in standing water and sand, while several homes along the shore of Hatteras Island collapsed into the sea.

NASA Selects Two Earth System Explorers Missions

NASA insignia.
Credit: NASA

Two next-generation satellite missions announced Thursday will help NASA better understand Earth and improve capabilities to foresee environmental events and mitigate disasters.

“NASA uses the unique vantage point of space to study our home planet to deliver life-saving data into the hands of disaster response and decision-makers every day for the benefit of all, while also informing future exploration across our solar system,” said Nicky Fox, associate administrator, Science Mission Directorate, NASA Headquarters in Washington. “By understanding Earth’s surface topography, ecosystems and atmosphere, while also enabling longer range weather forecasting, these missions will help us better study the extreme environments beyond our home planet to ensure the safety of astronauts and spacecraft as we return to the Moon with the Artemis campaign and journey onward to Mars and beyond.”

These two missions were selected for continued development as part of NASA’s Earth System Explorers Program, which conducts principal investigator-led Earth science missions based on key priorities laid out by the science community and national needs. The program is designed to enable high-quality Earth system science investigations to focus on previously identified key targeted observables.

The STRIVE (Stratosphere Troposphere Response using Infrared Vertically-resolved light Explorer) mission will provide daily, near-global, high-resolution measurements of temperature, a variety of Earth’s atmospheric elements, and aerosol properties from the upper troposphere to the mesosphere – at a much higher spatial density than any previous mission. It also will measure vertical profiles of ozone and trace gasses needed to understand the recovery of the ozone layer. The data collected from STRIVE would support longer-range weather forecasts, an important tool in protecting coastal communities, where nearly half the world’s population lives. The mission is led by Lyatt Jaeglé at the University of Washington in Seattle.

The EDGE (Earth Dynamics Geodetic Explorer) mission will observe the three-dimensional structure of terrestrial ecosystems and the surface topography of glaciers, ice sheets, and sea ice. The mission will provide an advancement beyond the measurements currently recorded from space by NASA’s ICESat-2 (Ice, Cloud, and land Elevation Satellite 2) and GEDI (Global Ecosystem Dynamics Investigation). The data collected by EDGE will measure conditions affecting land and sea transportation corridors, terrain, and other areas of commercial interest. The mission is led by Helen Amanda Fricker at the University of California San Diego.

The selected missions will advance to the next phase of development. Each mission will be subject to confirmation review in 2027, which will assess the progress of the missions and the availability of funds. If confirmed, the total estimated cost of each mission, not including launch, will not exceed $355 million with a mission launch date of no earlier than 2030.

Career Spotlight: Welder (Ages 14-18)

What does a welder do?

A welder uses tools that join two or more parts through forces such as heat or pressure. Metals are the materials most commonly used in welding, but it’s also possible to weld thermoplastics or wood. Welders use their hands, skills, and problem-solving abilities to create something new.

At NASA, welders use different types of welding processes to assemble spacecraft and rocket components. Welders also put their expertise to work on equipment and facilities that make space exploration possible, such as launch pads, fuel tanks, propellant lines, and buildings where rockets are assembled.

What are the different types of welding?

Welding can be done in many different ways. Here are some of the types of welding used at NASA:

  • Arc Welding: Uses electricity to melt metals and fuse them together. There are many types of arc welding, including TIG and MIG welding, described below.
  • Tungsten Inert Gas (TIG) Welding: Uses a protective gas like argon or helium to keep the metal from reacting with air. TIG welding doesn’t leave behind splatter or residue, giving a clean, precise weld.
  • Metal Inert Gas (MIG) Welding: While not as clean and precise as TIG welding, is used for fast, strong welds on thicker materials, like sheet metal.
  • Laser Welding: Enables welders to create tiny, perfect joints for delicate components.
  • Ultrasonic Welding: Uses sound and friction to create a solid-state bond between layers of metal.

NASA

How can I become a welder?

After graduating from high school, there are a couple of pathways to choose from. You can pursue an associate’s degree in welding, typically a two-year program available through community colleges and technical schools. Another option is to obtain a certificate from a vocational school or trade school. An apprenticeship during or after this training is often the next step toward a career as a professional welder.

How can I start preparing today to become a welder?

Taking a welding class at your high school or local college is a great way to find out whether it’s a skill you enjoy. Research welding degrees and programs at colleges and schools to determine which one(s) fit your needs and interest. It’s also a good idea to research job vacancies to learn what employers are looking for. Finally, seek out opportunities for hands-on experience to help you practice and improve your welding skills.

Advice from other NASA welders

  • “Building your knowledge in math and science is always a helpful tool, as you’ll need to understand measurements, geometry, and materials.” – Spencer Wells, engineering technician, Kennedy Space Center
  • “One of the best ways to set yourself up as a welder is by attending a vocational school for welding, and then working in an apprentice/internship to gain work experience and training.” – Enricque Lee, tool and die apprentice, NASA’s Glenn Research Center
On Jan. 13, 2016, technicians at Michoud Assembly Facility in New Orleans finished welding together the primary structure of the Orion spacecraft destined for deep space on Artemis I, marking another important step on the journey to Mars.
