Field Tests Help Prepare NASA Tech for Fire Season
Wednesday, 06 July 2022 08:34
Even before the summer's hottest, driest weather has arrived, wildfires have taken a heavy toll in some parts of the U.S. This spring, in collaboration with fire response teams, NASA researchers tested their prototype tools to help make the demanding job of wildland firefighters safer.

Wednesday, 06 July 2022 08:34
A 15-year study led by the Carnegie Institution for Science details the origins and diversity of every known mineral on Earth, a landmark body of work that will help reconstruct the history of life on Earth, guide the search for new minerals and ore deposits, predict possible characteristics of future life, and aid the search for habitable planets and extraterrestrial life.
In twin papers Large Hadron Collider project discovers three new exotic particles
Wednesday, 06 July 2022 08:34
The Large Hadron Collider beauty (LHCb) collaboration has announced the discovery of three new exotic particles. Exotic particles, such as these, had only been theorised but not observed until recently. These exotic particles are built out of quarks.
"Like proton or neutrons, the particles that make up the nucleus of the atom, these new particles are made up of quarks", explained Chris Par New launch vehicles set for test flights from China’s Jiuquan spaceport

Rover plus astronaut complete Mount Etna challenge
Wednesday, 06 July 2022 06:12
In a complex role-played version of a mission to the Moon, controllers at ESOC combined with a team of geological scientists and ESA astronaut Thomas Reiter to oversee a rover’s collection of rock samples. Acting as if he were in lunar orbit, the astronaut was in fact based in a hotel room in Catania, Sicily, with the rover 23 km away and 2 600 m uphill on the volcanic flanks of Mount Etna. As Thomas commanded the rover to pick up rocks his hand experienced just what the robot’s gripper felt – an added dimension in remote
Update on CAPSTONE communications issue
Tuesday, 05 July 2022 23:32
Following successful deployment and start of spacecraft commissioning on July 4, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) spacecraft experienced communications issues while in contact with the Deep Space Network.
The spacecraft team currently is working to understand the cause and re-establish contact. The team has good trajector Star with the shortest orbital period around black hole discovered
Tuesday, 05 July 2022 23:32
Researchers at the University of Cologne and Masaryk University in Brno (Czech Republic) have discovered the fastest known star, which travels around a black hole in record time. The star, S4716, orbits Sagittarius A*, the black hole in the centre of our Milky Way, in four years and reaches a speed of around 8000 kilometres per second. S4716 comes as close as 100 AU (astronomical unit) to the bl A new method for predicting the 11-year solar cycle strength

The Sun is our superstar, continuously providing our planet with energy, light, and heat, thus making it a very habitable environment for life. However, it is also the source of powerful explosions, which can affect astronauts and modern technologies in space and on Earth.

Surveying the cosmos from its isolated position in Antarctica, a collaborative project aims to reveal insights about the universe's beginnings.
In summer at the South Pole, which lasts from November through February, the average temperature is a biting minus 18 degrees F. The sun does not set during this time, making sleep a challenge.

The CAPSTONE orbiter left the low Earth orbit on its way to the moon, NASA said in a statement.
The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment is attached to Rocket Lab's Photon upper stage, which maneuvered CAPSTONE into position for its journey to the moon.

US announces a stop to testing anti-satellite weapons
Tuesday, 05 July 2022 16:53
The United States Government has declared that it will no longer be performing tests of anti-satellite (ASAT) weapons. In a public statement during a visit to the Vandenberg Space Force Base, Vice President Kamala Harris confirmed that this policy has the primary purpose of setting an example to other countries. It represents an important step in the direction of establishing "space norms" for all countries to follow.
ASAT weapons go as far back as the early years of the Cold War. According to the Naval Institute Guide to World Naval Weapons Systems, ASAT weapons were designed for strategic and tactical military purposes. Satellites have long been used by the military for navigation, communication, and gathering intel on enemy movements and activities through sophisticated satellite imaging: Spy satellites.
Although ASAT weapons have never been used in actual warfare, China, India, Russia, and the U.S. have all demonstrated their capability. These weapons have so far only been used by these countries in tests against their own targets, such as decommissioned satellites.
