These 18 awards are focused on boost-phase SBIs, weapons that can take out a missile soon after it leaves its silo. From a physics perspective, this is one of the most difficult things to ask an interceptor to do, because the weapon must account for atmospheric disturbances and reentry heating to reach its target. In ..

He then pondered out loud what would happen if people stopped getting vaccinated. “If we take away all of the herd immunity, then does that switch, does that teeter-totter switch in a different direction?” he asked. Backlash In a statement, AMA Trustee Sandra Adamson Fryhofer blasted the question. “This is not a theoretical debate—it is ..
“The suits that we have are definitely much better than Apollo,” Rubins said in the interview. “They were just big bags of air. The joints aren’t in there, so it was harder to move. What they did have going for them was that they were much, much lighter than our current spacesuits. We have added ..
Graphene is the thinnest material yet known, composed of a single layer of carbon atoms arranged in a hexagonal lattice. That structure gives it many unusual properties that hold great promise for real-world applications: batteries, super capacitors, antennas, water filters, transistors, solar cells, and touchscreens, just to name a few. The physicists who first synthesized ..
Welcome to Edition 8.26 of the Rocket Report! The past week has been one of advancements and setbacks in the rocket business. NASA rolled the massive rocket for the Artemis II mission to its launch pad in Florida, while Chinese launchers suffered back-to-back failures within a span of approximately 12 hours. Rocket Lab’s march toward ..
Campylobacter is a common cause of food poisoning and is on the rise in Michigan and around the world. It spreads to humans through food products made from, or that come into contact with, infected animals, primarily chickens and other birds. So far, only one outbreak of campylobacteriosis has been definitively linked to feces from ..
Really, really ancient mariners The hand stencil on the wall of Liang Metanduno is, so far, the oldest evidence of our presence in Wallacea, the group of islands stretched between the continental shelves of Asia and Australia. Populating these islands is “widely considered to have involved the first planned, long-distance sea crossing undertaken by our species,” ..
Researchers at Princeton University have built a swarm of interconnected mini-robots that “bloom” like flowers in response to changing light levels in an office. According to their new paper published in the journal Science Robotics, such robotic swarms could one day be used as dynamic facades in architectural designs, enabling buildings to adapt to changing ..
In this way, climate risk models today are better suited to characterize the “ broad environment of risk,” said Chris Field, director of the Stanford Woods Institute for the Environment. “ The more detailed you get to be either in space or in time, the less precise your projections are.” Matouka’s California climate risk plugin is ..
The launch team repaired a leaky hydrogen seal and introduced a gentler hydrogen loading procedure to overcome the problem. Hydrogen is an extremely efficient fuel for rockets, but its super-cold temperature and the tiny size of hydrogen molecules make it prone to leakage. The hydrogen feeds the SLS rocket’s four core-stage engines and single upper-stage ..
