Build-a-satellite program could fast track national security space missions

June 8, 2022 • ALBUQUERQUE, N.M. — Satellites equipped with remote sensing technology execute many critical national security missions, from detecting explosions to tracking sea ice, but until now it could take a team years to move from a concept to a deployable space system. Valhalla, a Python-based performance modeling framework developed at Sandia...

Armoring satellites to survive and operate through attacks

October 21, 2019 • ALBUQUERQUE, N.M. — Satellites do a lot of things — they help people navigate from one place to another, they deliver television programming, they search for new stars and exo-planets and they enable the U.S. nuclear deterrence strategy. But until recently, one thing they haven’t done — or needed to...

Origin of spooky meteor noises reappraised by Sandia researchers

February 17, 2017 • ALBUQUERQUE, N.M. — When a meteor is about to conk your neighborhood and gives fair warning by emitting sizzling, rustling and hissing sounds as it descends, you might think that the universe is being sporting. But these auditory warnings, which do occur, seem contrary to the laws of physics if...

Sandia’s Z machine helps solve Saturn’s 2-billion-year age gap

June 26, 2015 • Research supports 80-year-old prediction ALBUQUERQUE, N.M. — Planets tend to cool as they get older, but Saturn is hotter than astrophysicists say it should be without some additional energy source. The unexplained heat has caused a two-billion-year discrepancy for computer models estimating Saturn’s age. “Models that correctly predict Jupiter to...
