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.

Celebrating 100 Years Since Goddard’s Breakthrough Moment in Modern Rocketry

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 the universe, the use of liquid-fueled rockets has been key to humanity’s use and exploration of space. Today marks 100 years since the first successful test of this technology. On […]

A Combination of Techniques Leads to Improved Friction Stir Welding 

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).

NESC Develops Method for Estimating Risk When Reducing NDE 

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.

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 know much more about the patches where these strong magnetic fields […]
