Uncovering a novel way to bring to Earth the energy that powers the sun and stars
Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have uncovered critical new details about fusion facilities that use lasers to compress the fuel that produces fusion energy. The new data could help lead to the improved design of future laser facilities that harness the fusion process that drives the sun and stars.
Fusion combines light element DARPA's ANSR to Improving Trustworthy AI
Despite recent improvements to machine learning (ML) algorithms and assurance technologies, high levels of autonomy still remain elusive.
The reasons for this are twofold. First, data-driven ML lacks transparency, interpretability, and robustness and has unsustainable computational and data needs. Second, traditional approaches to building intelligent applications and autonomous systems th SEAKR Engineering Demonstrates Optical Communications on DARPA's Mandrake 2 Satellites
SEAKR Engineering, LLC, a wholly-owned subsidiary of Raytheon Technologies, announced a successful demonstration of optical inter-satellite links between two Defense Advanced Research Projects Agency Mandrake 2 satellites. During the first test, more than 280 gigabits of data were transferred at a range of 114 kilometers during a period of more than 40 minutes.

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.
"We looked at the current knowledge of the configuration of plate boundary zones and the past construction of the continental crust," said Dr Derrick Hasterok, Lecturer, Department o Asteroid samples contain 'clues to origin of life': Japan scientists
Asteroid dust collected by a Japanese space probe contains organic material that shows some of the building blocks of life on Earth may have been formed in space, scientists said Friday.
Pristine material from the asteroid Ryugu was brought back to Earth in 2020 after a six-year mission to the celestial body around 300 million kilometres away.

The face of Galileo James Webb telescope hit by micrometeoroid: NASA
A mirror on the James Webb Space Telescope was struck by a micrometeoroid last month but is expected to continue to function normally, NASA said Thursday.
"After initial assessments, the team found the telescope is still performing at a level that exceeds all mission requirements despite a marginally detectable effect in the data," the US space agency said.
"Webb's beginning-of-life performance is still well above expectations, and the observatory is fully capable of performing the science it was designed to achieve," it added.
One of the space observatory's primary mirror segments suffered an impact from a micrometeoroid, which tend to be smaller than a grain of sand, between May 23 and 25.
Scheduling NASA's Webb telescope's science
In the lead-up to the release of Webb's first full-color images and spectroscopic data on July 12, the Webb team is now in the last phase of commissioning the science instruments. The first two instrument modes, NIRCam imaging and NIRISS imaging, have been declared ready for science; watch the "Where is Webb" page as the team works their way through the other 15 instrument modes.
After commissioning is finished, the fun—and discoveries—will start: implementing the hundreds of peer-reviewed science programs that have been selected for Webb's first year. The area on the sky that Webb can see at any given time is called the field of regard. Deciding which observations to make on which day is a complicated process designed to optimize observational efficiency and manage the observatory's resources. We asked Christine Chen, science policies group lead at the Space Telescope Science Institute (STScI), to tell us how Webb's schedule comes together.
"Webb will soon transition from commissioning to regular operations when Webb's time will be devoted to scientific observations," said Christine Chen, Webb science policies group lead, Space Telescope Science Institute, Baltimore, Maryland.
