Historic UK satellite launch may spur military appetite

A mobile air-launched rocket system to be used in Britain's first domestic satellite launch could sow the seeds for a globally dispersed rapid-response capability to put extra eyes in space in times of war, executives and analysts said.

Virgin Orbit, part-owned by billionaire Richard Branson, plans to launch nine satellites from a LauncherOne rocket attached under the wing of a modified Boeing 747, to be flown from a new spaceport in Cornwall on Monday.

Scientists chip away at how ancient Roman concrete stood test of time

The ancient Romans were brilliant engineers and builders, creating a dazzling array of magnificent structures including some that have survived to modern times virtually intact like the domed Pantheon in Rome.

An indispensable material for the Romans was a form of concrete they developed that is known for remarkable durability and longevity, though its exact composition and properties have remained a mystery. A new study goes a long way toward solving this puzzle and, the researchers said, could pave the way for the modern use of a replicated version of this ancient marvel.

Omicron COVID booster cuts hospitalization in over 65s, https://srikandijepara.com/ Israeli study finds

The Omicron-adapted COVID-19 vaccine booster developed by Pfizer Inc and BioNTech SE sharply reduced hospitalizations among older patients, Israeli researchers said on Monday, in some of the first evidence of the jab's real-world effectiveness.

The study by researchers from healthcare provider Clalit, Ben-Gurion University of the Negev and Sapir College has not yet been peer reviewed.

Britain's groundbreaking satellite launch ends in failure

Britain's attempt to become the first European nation to launch satellites into space ended in bitter disappointment early on Tuesday when Virgin Orbit said its rocket had suffered an anomaly that prevented it from reaching orbit.

The "horizontal launch" mission had left from the coastal town of Newquay in southwest England, with Virgin's LauncherOne rocket carried under the wing of a modified Boeing 747 called "Cosmic Girl," and later released over the Atlantic Ocean.

Rocket released in Europe's first satellite launch

Virgin Orbit's LauncherOne rocket was released from its carrier aircraft late on Monday, a key stage of Western Europe's first satellite launch that took off from the coastal town of Newquay in southwest England.

The rocket was released from under the wing of a modified Boeing 747 out over the Atlantic Ocean, at about 35,000 feet (10,668 meters). Nine small satellites will be deployed from the vehicle.
