Successful startup of the LUX-ZEPLIN Dark Matter Detector at Sanford
Tuesday, 19 July 2022 09:33
Deep below the Black Hills of South Dakota in the Sanford Underground Research Facility (SURF), an innovative and uniquely sensitive dark matter detector - the LUX-ZEPLIN (LZ) experiment, led by Lawrence Berkeley National Lab (Berkeley Lab) - has passed a check-out phase of startup operations and delivered first results.
The take home message from this successful startup: "We're ready and Researchers use quantum-inspired approach to increase lidar resolution
Tuesday, 19 July 2022 09:33
Researchers have shown that a quantum-inspired technique can be used to perform lidar imaging with a much higher depth resolution than is possible with conventional approaches. Lidar, which uses laser pulses to acquire 3D information about a scene or object, is usually best suited for imaging large objects such as topographical features or built structures due to its limited depth resolution. NASA Ice Scientists Take Flight from Greenland to Study Melting Arctic Ice

Over the next two weeks, a handful of NASA scientists will be living very different lives from the rest of us: they will board a research plane in Greenland alongside laser instruments to help calibrate NASA's space-based measurements of Arctic ice.
The ice researchers and instrument scientists will board NASA's Gulfstream V jet and fly out of Thule Air Base in northwestern Greenland to he Ozone depletion over North Pole produces weather anomalies

Many people are familiar with the hole in the ozone layer over Antarctica, but what is less well known is that occasionally, the protective ozone in the stratosphere over the Arctic is destroyed as well, thinning the ozone layer there. This last happened in the spring months of 2020, and before that, in the spring of 2011.
Each time the ozone layer has been thinned out, climate researchers Great Air Quality for the Great Lakes Region
Tuesday, 19 July 2022 09:33
Air quality planning agencies in the U.S. Great Lakes region now include high-resolution NASA satellite data and near real-time Earth observations in their ozone pollution assessments. Creating models that accurately predict the complex lake and land breezes along Lake Michigan's shoreline is very difficult, but it's also vital to understanding how ozone pollution circulates in the region. Predicting equatorial plasma bubbles with SWARM
Tuesday, 19 July 2022 09:33
Changes in atmospheric density after sunset can cause hot pockets of gas called 'plasma bubbles' to form over the Earth's equator, resulting in communication disruptions between satellites and the Earth.
New AI models are now helping scientists to predict plasma bubble events and create a forecast. The work was presented this week at the National Astronomy Meeting (NAM 2022) by Sachin Redd New insights into the Earth's formation

Although the Earth has long been studied in detail, some fundamental questions have still to be answered. One of them concerns the formation of our planet, about whose beginnings researchers are still unclear. An international research team led by ETH Zurich and the National Centre of Competence in Research PlanetS is now proposing a new answer to this question based on laboratory experiments an A helping hand for Mars

The mission to return martian samples back to Earth will see a European 2.5 metre-long robotic arm pick up tubes filled with precious soil from Mars and transfer them to a rocket for an historic interplanetary delivery.
Sharpening satnav for smartphones
Tuesday, 19 July 2022 06:24
Satellite navigation has transformed the way people live and work, but because the majority of us access it via our smartphones, the actual precision of positioning that we end up with has plenty of room for improvement. ESA led a project investigating if an array antenna approach borrowed from satellite design might deliver enhanced positioning for future smartphones, tablets, drones and other mass-market devices.

SpaceX equals 2021′s launch total with current Starlink
Monday, 18 July 2022 16:22
SpaceX managed a record 31 launches in 2021, but its more-than-weekly pace in 2022 including a launch Sunday morning let it match that record less than seven months into the year.
A Falcon 9 rocket carrying 53 more of its Starlink internet satellites to orbit lifted off from Cape Canaveral Space Force Station's Space Launch Complex 40 at 10:20 a.m. Eastern Time.
This is the third time SpaceX used a first-stage booster for a record 13th time, with this booster having previously flown on Crew Dragon's first demonstration mission, the RADARSAT Constellation Mission, SXM-7 and nine Starlink missions. It's notably also been used at all three of SpaceX's launch facilities, having also taken off from Kennedy Space Center and Vandenberg Space Force Base on missions responsible for bringing nearly 600 payloads to space.
The majority of this year's launches have been in support of the growing Starlink internet constellation, which is now active in around 40 markets around the world. This marks the 17th Starlink launch of the year and 52nd Starlink launch since the first operational deployment in 2019, with more than 2,800 satellites sent to orbit.
The 570-pound satellites orbit at around 341 miles altitude.
Foust Forward | For JWST, celebrating the future while remembering the past

The technical achievements of deploying JWST and the anticipation about its first images have overcome what JWST had been known for: billions of dollars in cost overruns and years of schedule delays.
