SpaceX equals 2021′s launch total with current Starlink
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.
DirecTV says 5G plan would degrade satellite TV reception
DirecTV said July 18 its satellite TV customers face major disruption if broadcast rival Dish Network gets to deploy 5G wireless services in the 12 GHz spectrum band.

Sharpening satnav for smartphones
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.

Quantum physics: Record entanglement of quantum memories
A network in which data transmission is perfectly secure against hacking? If physicists have their way, this will become reality one day with the help of the quantum mechanical phenomenon known as entanglement. For entangled particles, the rule is: If you measure the state of one of the particles, then you automatically know the state of the other. It makes no difference how far away the entangl SpaceX launches 53 Starlink satellites to orbit after Dragon docks with ISS
SpaceX on Sunday launched 53 Starlink satellites after the company's Dragon cargo craft carrying crew supplies and scientific experiments docked with the International Space Station on Saturday.
The Starlink satellites were launched to orbit from a Falcon 9 rocket at the Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida at 10:20 a.m. Sunday.

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
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.
