Warming drives 'fundamental' changes to ocean, scientists warn
Climate change has wrought major changes to ocean stability faster than previously thought, according to a study published Wednesday, raising alarms over its role as a global thermostat and the marine life it supports.
The research published in the journal Nature looked at 50 years of data and followed the way in which surface water "decouples" from the deeper ocean.
Climate change has Florida company licenses NASA tech that keeps electronics cool
From shutting down unexpectedly to exploding, electronics can wreak havoc when they overheat. A Florida-based company called Protodromics LLC has licensed a NASA technology that takes advantage of a physical force called electrohydrodynamics (EHD) to pump water or other fluids and cool overheated electronics. Due to the technology's low power consumption, modular nature, and small size, it can b US military must accelerate use of artificial intelligence, JAIC chief says
The U.S. military must scale up its artificial intelligence use or be left behind by adversaries, Lt. Gen. Michael Groen told an industry conference this week.
Data must be standardized, cloud services must be adopted and AI must be integrated into military operations, Groen, chief of the Pentagon's Joint Artificial Intelligence Center, told the National Defense Industrial Association c Pentagon extends contract options for nuclear microreactor prototype
The Department of Defense awarded contract options this week to two companies to create a final prototype for a transportable advanced nuclear microreactor.
BWXT Advanced Technologies and X-energy, both of which won contracts last year to develop portable nuclear reactors, will continue that work under the new options, according to a Pentagon press release.
The teams are working Dubai reports launch of DMSat-1 Atmospheric Monitoring Microsatellite
Dubai Municipality announced the successful launch and deployment of DMSat-1, an atmospheric monitoring microsatellite built by Space Flight Laboratory (SFL). DMSat-1 launched Tuesday from the Baikonur Cosmodrome in Kazakhstan aboard a Soyuz rocket.
SFL developed DMSat-1 under contract to the Dubai-based Mohammed Bin Rashid Space Centre (MBRSC) in the United Arab Emirates (UAE). The 15-kg AFRL directed energy industry days
The Air Force Research Laboratory Directed Energy Directorate will host a Virtual Briefing for Industry to introduce the new Directed Energy Technology Experimentation Research (DETER), Advanced Research Announcement (ARA) April 13 - 14 from 10 a.m. to noon Mountain Standard Time each day.
"We are looking forward to hosting our first briefing for industry days," said Marcella Cantu, DETER Engine of Atlantis

The second European Service Module that will power the Orion spacecraft on a crewed flyby of the Moon is fitted with a special engine at Airbus facilities in Germany.
This engine belonged to Space Shuttle Atlantis, and is one of five refurbished engines to be paired with the first five European Service Modules. Technicians carefully install the engine in Airbus’ cleanroom.
ESM is the powerhouse of NASA’s Orion spacecraft. It will provide critical functions such as the propulsion system to get astronauts to the Moon, and the consumables astronauts need to stay alive.
ESM-2 will fuel the crewed Orion spacecraft during a
NASA engineers analyze navigation needs of Artemis moon missions
Space communications and navigation engineers at NASA are evaluating the navigation needs for the Artemis program, including identifying the precision navigation capabilities needed to establish the first sustained presence on the lunar surface.
"Artemis engages us to apply creative navigation solutions, choosing the right combination of capabilities for each mission," said Cheryl Gramling, associate chief for technology in the Mission Engineering and Systems Analysis Division at Goddard Space Flight Center in Greenbelt, Maryland. "NASA has a multitude of navigation tools at its disposal, and Goddard has a half-century of experience navigating space exploration missions in lunar orbit."
Alongside proven navigation capabilities, NASA will use innovative navigation technologies during the upcoming Artemis missions.
"Lunar missions provide the opportunity to test and refine novel space navigation techniques," said Ben Ashman, a navigation engineer at Goddard. "The moon is a fascinating place to explore and can serve as a proving ground that expands our navigation toolkit for more distant destinations like Mars.
Space vs. materials – orbital testing outside Space Station
Space leaves its mark on materials: exposure to such a harsh environment can darken, crack or crater their surfaces – or even erode them away entirely. The nothingness of hard vacuum can also provoke ‘outgassing’ vapours from materials that might degrade delicate mission systems. Accordingly ESA and the French space agency CNES are giving European researchers the chance to pit the latest aerospace materials directly against space.
Lockheed Martin awarded $3.7B to modernize key missile defense mission
The Missile Defense Agency (MDA), in a competitive downselect phase, selected Lockheed Martin (NYSE: LMT) and partner Aerojet Rocketdyne (NYSE: AJRD) to deliver the nation's most advanced missile defense system, the Next Generation Interceptor (NGI).
The $3.7 billion contract for Next Generation Interceptor is the first step in the development and demonstration phase delivering on MDA's re
