Northrop Grumman delivers mini laser to US Government
Thursday, 31 August 2023 07:35Northrop Grumman Corporation (NYSE: NOC) has delivered a miniaturized high-energy laser source to the U.S. government. The laser is ruggedized for field use and miniaturizing it allows for rapid placement in tactical situations. The 10kW class high-energy laser, known as Phantom, is about 12 cubic feet (nearly the size of a mini fridge). Weighing less than 200 pounds, it enables lift

This multiple award contract provides awardees the opportun
Last 'Super Blue Moon' until 2037
Thursday, 31 August 2023 07:35Astronomy enthusiasts are in for a treat Wednesday night: a rare "super blue Moon" that won't be seen again for more than a decade. Supermoons occur when the Moon passes through its perigee, or the point that takes it closest to Earth during its elliptical orbit. This makes it look about 14 percent bigger compared to when it is at its furthest point, and a touch brighter. Full Moons are

Wednesday, 30 August 2023 18:50A swarm of swimming microbots could be deployed to Europa's ocean
Wednesday, 30 August 2023 17:35Europa and other ocean worlds in our solar system have recently attracted much attention. They are thought to be some of the most likely places in our solar system for life to have developed off Earth, given the presence of liquid water under their ice sheathes and our understanding of liquid water as one of the necessities for the development of life.
Various missions are planned to these ocean worlds, but many suffer from numerous design constraints. Requirements to break through kilometers of ice on a world far from the sun will do that to any mission. These design constraints sometimes make it difficult for the missions to achieve one of their most important functions—the search for life. But a team of engineers from NASA's Jet Propulsion Laboratory think they have a solution—send forth a swarm of swimming microbots to scour the ocean beneath a main "mothership" bot.
One of the most likely forms of the mothership bot for this mission is the Subsurface Access Mechanism for Europa—SESAME.
Sahara space rock 4.5 billion years old upends assumptions about the early solar system
Wednesday, 30 August 2023 14:20In May 2020, some unusual rocks containing distinctive greenish crystals were found in the Erg Chech sand sea, a dune-filled region of the Sahara Desert in southern Algeria.
On close inspection, the rocks turned out to be from outer space: lumps of rubble billions of years old, left over from the dawn of the solar system.
They were all pieces of a meteorite known as Erg Chech 002, which is the oldest volcanic rock ever found, having melted long ago in the fires of some now-vanished ancient protoplanet.
In new research published in Nature Communications, we analyzed lead and uranium isotopes in Erg Chech 002 and calculated it is some 4.56556 billion years old, give or take 120,000 years. This is one of the most precise ages ever calculated for an object from space—and our results also cast doubt on some common assumptions about the early solar system.
The secret life of aluminum
About 4.567 billion years ago, our solar system formed from a vast cloud of gas and dust.
Wired for space - Muscle stimulation to enhance astronaut health
Wednesday, 30 August 2023 13:30Space exploration presents unique health challenges for astronauts due to lack of gravity, isolation, and radiation exposure. ESA's SciSpacE activities aim to comprehend these effects and their implications for human well-being during extended missions.
ESA collaborates with researchers to conduct experiments in microgravity and analogue environments, shedding light on the consequences of space stressors. One critical concern is muscle and bone atrophy. Despite daily exercise routines, astronauts face deterioration. ESA is investigating electrical stimulation as a potential countermeasure, with tests planned on board the International Space Station.
The "Muscle Stimulation" experiment is a centrepiece of this research. By applying

PSI study shows evidence of highly mobile lunar regolith
Wednesday, 30 August 2023 09:45Swirls are enigmatic albedo (light reflection) patterns on the lunar surface associated with local magnetic anomalies. The processes involved in their formation have been examined and debated since their discovery. The most popular idea is shielding of the surface from solar wind radiation by the associated magnetic anomaly. This explains the swirling pattern, as shielded material would be brigh

Dead stars cast long shadows: WVU astronomer hunts for the glowing ghosts of supernovas
Wednesday, 30 August 2023 09:45A West Virginia University astronomer is searching the Milky Way for debris left behind by supernovas, the violent explosions that occur when massive stars die. After a supernova explosion, material that was part of the star expands outward, forming a shell or "remnant." According to Loren Anderson, professor at the Eberly College of Arts and Sciences, studying supernova remnants is "essen
