The people of stockpile stewardship are the key to LLNL’s success
The last nuclear test, code-named Divider, took place 30 years ago, on Sept. 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent during the Clinton administration. This ending of the era of nuclear testing was also the beginning of stockpile stewardship. Leaders from the Department of Energy (DOE), and Lawrence…
Scientific discovery for stockpile stewardship

Developing technology to keep the nuclear stockpile safe, secure and reliable
The last nuclear test, code-named Divider, took place 30 years ago, on Sept. 23, 1992. That year, President Bush declared a temporary moratorium on nuclear testing, which became permanent in 1995, during the Clinton administration. This ending of the era of nuclear testing coincided with a Presidential announcement of the beginning of stockpile stewardship. As the decision…
LLNL-led paper reveals spacecraft geometry effects on impact simulations for NASA’s DART Mission
NASA’s Double Asteroid Redirection Test (DART) spacecraft will crash into asteroid Dimorphos on Sept. 26, executing the first asteroid deflection test that has been years in the planning. Dimorphos, at 150 meters across, is the “moonlet” of a binary asteroid system, orbiting the larger companion asteroid, Didymos (800 meters). The momentum of the ~600 kg spacecraft,…
