NASA taps Livermore photon scientists for heat-shield research
Researchers in Lawrence Livermore National Laboratory's NIF & Photon Science Directorate are working with NASA Ames Research Center at Moffet Field, California on the development of technology to simulate re-entry effects on the heat shield for the Orion spacecraft, NASA's next crewed spaceship. Orion is designed to carry astronauts beyond low Earth orbit to deep-space…
Lawrence Livermore 'space cops' to help control traffic in space
A team of Lawrence Livermore National Laboratory scientists are using mini-satellites that work as "space cops" to help control traffic in space. The scientists used a series of six images over a 60-hour period taken from a ground-based satellite to prove that it is possible to refine the orbit of another satellite in low earth orbit."Eventually our satellite will be…
Meteorite made up of rare early solar system material
It looked like a fireball in the sky. It created a sonic boom. It vaporized upon entering the atmosphere. It's all of the above: The Sutter's Mill Meteorite had the force of 4 kilotons of TNT upon descent and spilled samples of itself over the towns of Columa and Lotus in northern California when it hit Earth last spring. And now a consortium of scientists including…
Livermore students speak live with astronauts in space
Students at Livermore's Junction Avenue School had an opportunity that was "out of this world." They got the chance on Wednesday to talk with three astronauts via an in-flight education downlink from the International Space Station (ISS). The entire school's student body -- from kindergarten to 8th grade -- assembled in two locations to watch the videoconference. "What a…
Putting the squeeze on planets outside our solar system
LIVERMORE, Calif. -- Just as graphite can transform into diamond under high pressure, liquid magmas may similarly undergo major transformations at the pressures and temperatures that exist deep inside Earth-like planets. Using high-powered lasers, scientists at Lawrence Livermore National Laboratory and collaborators discovered that molten magnesium silicate undergoes a…
Oldest objects in solar system indicate a turbulent beginning
LIVERMORE, Calif. -- Scientists have found that calcium, aluminum-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the mid-plane of the solar system. The findings may lead to a greater understanding of how our solar system and possibly other solar systems formed and evolved. CAIs, roughly…
New pictures show fourth planet in giant version of our solar system
Astronomers have discovered a fourth giant planet, joining three others that, in 2008, were the subject of the first-ever pictures of a planetary system orbiting another star other than our sun. The solar system, discovered by a team from Lawrence Livermore National Laboratory and the National Research Council of Canada (NRC) Herzberg Institute of Astrophysics with…
