LLNL leads new DART Mission paper on inferring asteroid material properties from deflection test

Sept. 26, 2022- 
Today at 4:14 p.m. (PDT), NASA’s Double Asteroid Redirection Test (DART) Mission will execute the first-ever asteroid-deflection test by crashing into asteroid Dimorphos. Traveling at ~6 km/s with a mass of ~600 kg, the DART spacecraft will transfer enough momentum for the imparted change in velocity to be detectable from Earth-based telescopes. However, there is significant...

Playing it safe: LLNL scientist creates energetic compounds with isotopic labels

Nov. 30, 2021- 
Ana Racoveanu is able to do something most others throughout the nuclear security enterprise cannot do — something challenging and extremely valuable throughout the complex.  Racoveanu, a staff scientist in Lawrence Livermore National Laboratory’s Materials Science Division, is able to synthesize energetic compounds with isotopic labels. The primary goal of this work is to...

Nuclear weapons technology for a new generation of policymakers

Oct. 27, 2021- 
Policymaking for nuclear security requires a strong grasp of the associated technical matters. That grasp came naturally in the early decades of the nuclear era, when scientists and engineers were deeply engaged in policymaking. Yet in the last few decades, the scientists and engineers who conceived, built and executed the programs that created the existing U.S. nuclear deterrent faded...

Making it count: Rebuilding infrastructure at the Nuclear Counting Facility

Oct. 8, 2021- 
When Daniel Martin put the finishing touches on an autonomous vehicle robot, complete with an ultrasonic sensor to detect and evade obstacles, he knew he wanted to become an engineer. A high school student at the time, he was fascinated by the design and functionality of robots. Fast forward several years, and Martin is now a second-year electrical engineering Ph.D. student at the University...

Just how big was the 2020 Beirut explosion?

Oct. 6, 2021- 
On Aug. 4, 2020, one of the largest non-nuclear explosions in history pulverized a Beirut port and damaged more than half the city. The explosion resulted from the detonation of tons of ammonium nitrate, a combustible chemical compound commonly used in agriculture as a high-nitrate fertilizer, but which can also be used to manufacture explosives. Since that time, the explosive yield...

Late-time small-body disruptions can protect the Earth

Oct. 5, 2021- 
If an asteroid is determined to be on an Earth-impacting trajectory, scientists typically want to stage a deflection, where the asteroid is gently nudged by a relatively small change in velocity, while keeping the bulk of the asteroid together. A kinetic impactor or a standoff nuclear explosion can achieve a deflection. However, if the warning time is too short to stage a successful...
