New microbe discovered aboard Chinese space station

"Scientists have identified a new microbe that developed on board China's Tiangong space station, according to a new study.
The strain, officially named niallia tiangongensis, is a new variant of a terrestrial bacteria and was found in a cabin inside the space station.
The discovery holds major implications for future space missions, astronaut health, and biosecurity.
Niallia tiangongensis demonstrated noteworthy resilience to space-specific stressors, including enhanced repair from radiation damage and the ability to survive oxidative stress—factors critical for maintaining long-term spaceflight safety.
Samples were stored at very low temperatures, returned to Earth, and subjected to genomic, metabolic, and phylogenetic analysis.
Researchers found that the new strain belongs to the genus niallia in the family cyto bacillaceae, but is genetically distinct from known relatives on Earth." ms

Trump Unveils $175 Billion Plan For "Golden Dome" Missile Defense System

"The Department of Defense has selected a design for President Donald Trump’s Golden Dome” missile defense initiative, Trump announced.
I’m pleased to announce that we have officially selected an architecture for this state-of-the-art system that will deploy next-generation technologies across the land, sea, and space, including space-based sensors and interceptors,” Trump told reporters at the White House.
In his first week in office, Trump signed an executive order directing the Department of Defense to devise a plan to implement his missile defense proposal.
It should be fully operational before the end of my term. So we'll have it done in about three years,” the president said.
Trump said the plan the Department of Defense has selected should cost about $175 billion to complete.
The plan will meld new technologies with existing U.S. missile defense systems.
Canada may also partner with the United States to help develop the improved missile defense shield, the president said. “Canada wants to be a part of it, which would be a fairly small expansion, but we'll work with them on pricing.”
