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 [...]
NASA’s crawler-transporter 2, carrying NASA’s Artemis II SLS (Space Launch System) rocket with the Orion spacecraft, arrives Wednesday, Feb. 25, 2026, inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida to troubleshoot the flow of helium to the rocket’s upper stage, the interim cryogenic propulsion stage. Once complete, the SLS rocket will roll back to Launch Complex 39B to prepare to launch four [...]

7 min read 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 [...]

Download PDF: 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 [...]
Download PDF: NESC Develops Method for Estimating Risk When Reducing NDE Performing nondestructive evaluation (NDE) can have both cost and schedule impacts, leading some to question whether descoping (i.e., reducing or eliminating) NDE inspections on certain spaceflight hardware could be possible. However, this approach would be counter to NASA’s Technical Standard NASA-STD-5019A, which outlines the spaceflight [...]
2 min read Volunteers Find Oddly High Solar Flare Rates Patches of the Sun’s surface often show strong magnetic fields. These fields can emerge within a matter of hours, and can decay slowly or quickly, sometimes over days, weeks, or even months. Thanks to a new study about these long-lived active regions, we now [...]
