The Deep Purple telescope developed by Lawrence Livermore National Laboratory (LLNL) researchers is now operational in space. The Livermore instrument, which utilizes a new design for an ultra-violet (UV) and short-wave infrared monolithic telescope features a novel, compact optical system and electronics package inside a lightweight, modular housing. On Friday, Aug. 16,…
Unveiling Bennu asteroid samples
Now at Lawrence Livermore National Laboratory (LLNL) lies a piece of ancient history. Very ancient history. The material, at just 120 milligrams, will provide information about the early solar system, planetary formation, and potentially, even ingredients for life on ancient Earth. LLNL scientists recently received and will analyze samples from the asteroid Bennu that will…
LLNL delivers compact dual-band telescope for launch this summer
Lawrence Livermore National Laboratory’s (LLNL) space hardware team has delivered a payload for NASA’s Pathfinder Technology Demonstrator-R (PTD-R) satellite. LLNL developed the optical payload, called Deep Purple, that utilizes a new design for an ultra-violet (UV) and short-wave infrared (SWIR) monolithic telescope. The mission will demonstrate simultaneous monolithic UV…
LLNL gamma-ray sensor has the best resolution
It’s official. An instrument designed and built by Lawrence Livermore National Laboratory (LLNL) researchers is the highest-resolution gamma ray sensor that has ever flown in space. The Livermore high-purity germanium (HPGe) gamma ray sensor is an essential part of a larger gamma-ray spectrometer (GRS) built in collaboration with researchers from Johns Hopkins Applied…
Finding Livermore: Employees share their LLNL origin stories
With more than 70 years of history and nearly 9,000 current employees, it is not uncommon for several generations of family members to have worked at Lawrence Livermore National Laboratory (LLNL). For those employees with parents or grandparents preceding them, a career at the Laboratory was not in their original plans. In fact, before coming to LLNL, many do not realize…
Mystery of puffy exoplanet solved
A recent study of the atmosphere of the exoplanet WASP-107b suggests tidal heating is responsible for the exoplanet’s inflated nature and reveals a previously unseen combination of molecules in an exoplanet. A Lawrence Livermore National Laboratory (LLNL) scientist and international collaborators have characterized the atmosphere of the exoplanet, WASP-107b, using a…
Lab to provide optical payload for upcoming U.S. Space Force mission
Lawrence Livermore National Laboratory’s (LLNL) Space Program is now building an optical space domain awareness payload for an upcoming mission by the U.S. Space Force. The planned mission, known as VICTUS HAZE, will be a tactically responsive space mission to demonstrate the ability to rapidly characterize an on-orbit threat. The U.S. Space Force selected Long Beach,…
LLNL Pandora SmallSat mission clears major NASA milestone on the path toward launch
Lawrence Livermore National Laboratory’s (LLNL) Pandora SmallSat mission recently passed NASA’s critical design review: a major milestone for the mission to continue its journey toward launch. The Pandora SmallSat mission will study planets beyond our solar system, known as exoplanets, and their stars. “This is a major milestone for the mission and a huge accomplishment…
See the solar corona: an intricate pattern reveals itself during the April 8 eclipse
On Monday, April 8, a swath of North America will experience a total solar eclipse. For a few minutes, the moon will completely obscure the sun and viewers will be able to see the intricate loops and flares in the solar corona—normally washed out by the bright disk of the sun. In the corona, the outermost, gaseous part of the sun’s atmosphere, particles dance around…
New nuclear deflection simulations advance planetary defense against asteroid threats
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a modeling tool for assessing the potential use of a nuclear device to defend the planet against catastrophic asteroid impacts. The research, published today in the Planetary Science Journal, introduces a novel approach to simulating the energy deposition from a nuclear device on an asteroid's…
Resolving astronomical mysteries
A new satellite called XRISM (X-ray Imaging and Spectroscopy Mission, pronounced “crism”) was successfully launched from the Tanegashima Space Center in Japan on Sep. 7, 2023. XRISM is a collaboration between the Japan Aerospace Exploration Agency (JAXA) and National Aeronautics and Space Administration (NASA), with European Space Agency participation, to study extreme…
Lab instrument now on two-billion-mile journey to the metallic asteroid Psyche
An instrument designed and built by Lawrence Livermore National Laboratory (LLNL) researchers departed Earth last week on a two-billion-mile, nearly six-year journey through space to explore a rare, largely metal asteroid. The Livermore high-purity germanium (HPGe) gamma-ray sensor is an essential part of a larger gamma-ray spectrometer (GRS) built in collaboration with…
Ripple effects: LLNL internships propel students forward with real-world projects
Every year, Lawrence Livermore National Laboratory (LLNL) welcomes hundreds of interns for an experiential, hands-on approach to learning. Working with some of the brightest minds in their fields, LLNL’s interns have the opportunity to explore new projects, build their skills, connect with mentors and integrate into Lab culture — resulting in a meaningful experience that…
LLNL’s prototype telescope now fully operational aboard the International Space Station
When SpaceX’s Dragon spacecraft docked with the International Space Station (ISS) on March 16, it delivered several thousand pounds of supplies for the crew as well as new hardware. The hardware included the U.S. Space Force’s Space Test Program Houston 9 (STP-H9) platform, which houses a prototype telescope designed and built by Lawrence Livermore National Laboratory's…
Lab engineer shares in DOE project award for work on the Vera C. Rubin Observatory
A Lawrence Livermore National Laboratory (LLNL) engineer and the SLAC National Accelerator Laboratory are among those sharing a Department of Energy (DOE) award for their roles in building the world’s newest observatory. The DOE honor, the 2021 project management achievement award, was recently presented for work done on the Legacy Survey of Space and Time camera (LSSTCam)…
#YourPlaceInSpace: LLNL planetary defender promotes career opportunities in the federal space workforce
Planetary defense physicist Megan Bruck Syal on Wednesday represented Lawrence Livermore National Laboratory (LLNL) at “Space STEM Task Force Pathways to the Federal Space Workforce,” an outreach event hosted by the National Science Foundation. Multiple federal government agencies came together in a virtual interactive session to provide information for students, early…
Prototype telescope designed by LLNL researchers launched to the International Space Station
A prototype telescope designed and built by Lawrence Livermore National Laboratory (LLNL) researchers has been launched from Cape Canaveral, Fla., to the International Space Station (ISS).

High-fidelity simulation offers insight into 2013 Chelyabinsk meteor
On the morning of Feb. 15, 2013, a small asteroid exploded over Chelyabinsk, Russia, sending a loud shockwave and sonic boom across the region, damaging buildings and leaving around 1,200 people injured. The resulting meteor, with a diameter of approximate 20 meters (roughly the size of a six-story building), was one of the largest to be detected breaking up in the Earth’s…
Study looks at velocity impact to asteroid Dimorphos
The first peer-reviewed results from NASA’s Double Asteroid Redirection Test (DART) mission were published Wednesday by Nature, including contributions from LLNL’s planetary defense team. The DART spacecraft executed a successful hypervelocity impact of 150-meter asteroid Dimorphos on Sept. 26, 2022. Analysis by Earth-based telescopes determined that the impact…
