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.

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.

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.

Cosmologist and author of "Losing the Nobel Prize" Brian Keating tells the inside story of BICEP2’s mesmerizing discovery and the scientific drama that ensued in this interview with science fiction author David Brin. Keating describes a journey of revelation and discovery, bringing to life the highly competitive, take-no-prisoners, publish-or-perish world of modern science. Along the way, he provocatively argues that the Nobel Prize, instead of advancing scientific progress, may actually hamper it, encouraging speed and greed while punishing collaboration and bold innovation. In a thoughtful reappraisal of the wishes of Alfred Nobel, Keating offers practical solutions for reforming the prize, providing a vision of a scientific future in which cosmologists may, finally, be able to see all the way back to the very beginning.
