Asteroid Bennu’s Rugged Surface Baffled NASA, We Finally Know Why
In one of the biggest surprises of NASA’s OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches that earlier observations from Earth-based instruments had indicated. “When OSIRIS-REx got to Bennu in 2018, we were surprised by what we saw,” said Andrew Ryan, a scientist with…

Hail Yeah! NASA Researchers Use Volunteer Observations for Hail Estimates
The bigger the hailstone, the more damage it can cause. But scientists find that predicting hailstone size can be challenging. How quickly does hail melt as it falls? Now, you can help tackle this question by joining the SouthEast Region CoCoRaHS Hail (SEaRCH) project. This network of backyard weather observers includes volunteers of all ages and backgrounds who work together to measure…

A Bit of Gray on an Emerald Isle
Today’s story is the answer to the March 2026 puzzler. Though Ireland is known for the many shades of green that grace its grassy pastoral landscapes, there’s one corner of the Emerald Isle where gray reigns supreme. In the Burren region, on the island’s west coast, what geologists describe as limestone pavement covers much of the rocky, treeless landscape. The OLI (Operational Land Imager) on Landsat 8 captured this view of the Burren on…

To Protect Artemis II Astronauts, NASA Experts Keep Eyes on Sun
As four astronauts travel around the Moon on NASA’s Artemis II mission, they will venture beyond Earth’s protective magnetic field. The crew’s spacecraft, Orion, will carry and protect them as they journey into deep space and serves as the main protection against the Sun’s intense power. During their 10-day flight, NASA and the National Oceanic and Atmospheric Administration (NOAA) will monitor the Sun around the clock and translate space weather…

SPARCS CubeSat ‘First Light’ Images
Description This pair of images shows stars observed by the SPARCS (Star-Planet Activity Research CubeSat) space telescope simultaneously in the near-ultraviolet, left, and far-ultraviolet, right. These observations were recorded on Feb. 6, 2026, three weeks after the cube satellite, or CubeSat, launched aboard a SpaceX Falcon 9 on Jan. 11. The fact that one star is seen in the far-UV…

A Combination of Techniques Leads to Improved Friction Stir Welding
The NESC developed several innovative tools and techniques during an assessment to find the root cause of poor tensile strength and low topography anomalies (LTA) in welds formed using a solid-state welding process called self-reacting friction stir welding (SRFSW). Using a combination of machine learning, statistical modeling, and physics-based simulations, the assessment team helped improve the weld process and solve…

Cañon Fiord’s Whirling Waters
For most of the year, ice blankets the waterways of the northern Canadian Arctic Archipelago. But during the brief summer melt season, the stark white and gray landscape transforms into a colorful, dynamic environment. On a particularly striking day in 2022, sediment plumes and fractured sea ice traced swirling eddies in a branch of the Nansen Sound fjord system. These…
