Cracking the chicken-and-egg problem of utilizing resources in space has been a difficult challenge for over half a century. Getting enough infrastructure built up is necessary to collect those resources effectively, but doing so is too expensive without using the resources themselves. Go to Source Medal of Valor recipients will include four Tenn. officers who responded to the Covenant School shooting and an officer who swam into frigid water to save a woman trapped in a vehicle Go to Source A new study in published in Physical Review Letters analyzes the most complete set of galaxy clustering data to test the ΛCDM model, revealing discrepancies in the formation of cosmic structures in the universe, hinting at a new physics. Go to Source Machu Picchu is one of the most incredible sites on the planet. The breathtaking architecture and design surpasses the limits and imagination of engineering, it is an incredible accomplishment and offers breathtaking experiences where a person gets lost in time and space while enjoying the amazing sight Machu Picchu offers. Located “just” three thousand […] SpaceX put the final countdown in the books for the Space Coast early Tuesday, adding one more to the record pace of launches for the year. Go to Source Apollo astronauts set up mirror arrays, or “retroreflectors,” on the moon to accurately reflect laser light beamed at them from Earth with minimal scattering or diffusion. Retroreflectors are mirrors that reflect the incoming light back in the same incoming direction. Go to Source Prof Zhang Zhiyong’s team at Peking University developed a heterojunction-gated field-effect transistor (HGFET) that achieves high sensitivity in short-wave infrared detection, with a recorded specific detectivity above 1014 Jones at 1300 nm, making it capable of starlight detection. Their research was recently published in the journal Advanced Materials, titled “Opto-Electrical Decoupled Phototransistor for Starlight Detection.” […] A top-secret lab in the UK is developing the country’s first quantum clock to help the British military boost intelligence and reconnaissance operations, the defense ministry said Thursday. Go to Source Image source: Caral Project / AP The ancient Peruvian coastal civilization called Caral has puzzled archaeologists for years, but perhaps one of the most important discoveries made in Peru is a writing system believed to be the earliest form of communication in the world and according to historians, equivalent in age to the cuneiform […] It’s slightly larger than a 5-liter water bottle, and is whizzing around the Earth at a speed of 7.5 kilometers per second. The satellite has two cameras built into its body, and can be controlled quickly and turned smoothly in all directions. Go to Source By the end of this decade, nations and private companies may well be mining the surface of the moon. Go to Source Sometimes, it’s hard to remember that Earth is constantly being bombarded by literally tons of space debris daily. The larger bits form what we know as shooting stars, and most burn up in the atmosphere. Still, throughout our planet’s history, giant versions have caused devastation unlike anything else seen on this planet. Tracking these types […] Blue Origin has achieved an important milestone with its New Glenn NG-1 rocket, successfully completing a 24-second hotfire of the rocket’s BE-4 engines in preparation for an expected test flight in the coming days. Go to Source Getting back to the moon is the primary goal of NASA’s Artemis program, but what do we do once we get there? That is the challenge tackled by a group of students at the University of Illinois Urbana-Champaign, who wrote a proposal for a lunar infrastructure module they call the Trans-lunar Hub for Exploration, ISRU, […] Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major benefits from improving the efficiency of infrared sensors, such as photodiodes. Go to Source |
