    Solar Probe Touches the Sun

    Solar Probe Touches the Sun

    Launched in 2018, NASA’s Parker Solar Probe spacecraft, with instruments developed and built by UC Berkeley, has now traveled closer to the sun than any other mission in history, actually penetrating the sun’s atmosphere, to investigate highly charged magnetic field. Now, that data has allowed solar physicists to map the source of a major component of the solar wind that continually peppers Earth’s atmosphere, while revealing strange magnetic field reversals that could be accelerating these particles toward our planet. These accelerated particles interact with Earth’s magnetic field, generating the colorful northern and southern lights but also potentially damaging the electrical grid and telecommunications networks on the surface, threatening orbiting satellites and perhaps endangering astronauts in space.

    Dark Threads of the Cosmic Web Revealed

    Dark Threads of the Cosmic Web Revealed

    A computational approach inspired by the growth patterns of a slime mold has enabled a team of astronomers and computer scientists at UC Santa Cruz to trace the filaments of the cosmic web that connects galaxies throughout the universe. Series: "UCTV Prime" [Science] [Show ID: 36784]

    Return to Apollo: Geologic Evolution of a Young Moon

    Return to Apollo: Geologic Evolution of a Young Moon

    New state-of-the-art chronologic measurements of rocks brought to Earth by Apollo astronauts reveal that many of the historical age determinations are erroneous. The new measurements presented by cosmochemist Lars Borg demonstrate that the Moon's mantle and crust formed contemporaneously between 4.33 and 4.38 billion years ago.

    Health in Space: Developing New Tools for the Trip to Mars

    Health in Space: Developing New Tools for the Trip to Mars

    Limited medical equipment on space craft makes medical care in space a real challenge. Ordinary problems must be dealt with, as well as problems related to the unique environment of space. As NASA plans for new crewed exploration missions, beyond low earth orbit, telemedicine support will be limited, and medical evacuation to earth will no longer be possible. To address this problem, LLNL and NASA Ames Research Center are developing a novel diagnostic instrument to help provide medical care on deep space missions. The technology consists of a blood analysis system, based on microfluidics, together with a breath analysis system that uses carbon nanotube sensors. The technology is designed to support future missions to the moon and Mars, and it is expected to be used for terrestrial medicine as well, in a variety of arenas where medical resources are limited.

    Planetary Defense: Avoiding a Cosmic Catastrophe

    Planetary Defense: Avoiding a Cosmic Catastrophe

    Our planet has been continually bombarded by asteroids since its formation, 4.5 billion years ago. While the frequency of large impacts has decreased, many potential Near-Earth Object threats remain undiscovered, so if or when they will impact Earth remains unknown. Fortunately, if an Earth-threatening asteroid is discovered in time, there are ways to mitigate or even prevent a disaster. Scientists at LLNL provide computer simulations in preparation these scenarios so if the time comes where an asteroid is headed our way, we will be prepared.
