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 [...]

Goddard and a liquid oxygen-gasoline rocket in the frame from which it was fired on March 16, 1926, at Auburn, Mass.Esther Goddard, from the Clark University archive From the voyages of spacecraft to the Moon and beyond, to the launches of satellites that help us navigate, communicate, and understand our planet and [...]
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 [...]

In addition to data received nightly from the Catalina Sky Survey’s Mt. Lemmon telescope in Arizona, the project’s science team is now processing images from the Bok 2.3-meter telescope at Kitt [...]
NASA’s Goddard Space Flight Center/Intuitive Machines Early morning sunlight illuminates the western wall of this unnamed crater, leaving deep shadows on the ground and in the interior. The image was taken on August 30, 2023, by LROC (Lunar Reconnaissance Orbiter Camera). LROC is a system of three cameras and one of the seven instruments aboard [...]
