When Yale research psyhcologist Irving Janis coined the term "groupthink" in 1972, he identified eight symptoms of the pathology: the "illusion of invulnerability"; a "belief in the inherent morality of the group"; "collective rationalization"; "out-group stereotypes"; "self-censorship"; the "illusion of unanimity"; "direct pressure on dissenters" and "self-appointed mindguards."

There are an estimated 129 million tiny bits of debris floating in orbit that, due to their high velocity, can cause catastrophic damage to space vehicles and satellites. Rensselaer Polytechnic Institute researchers are developing a compact orbiting device to semi-autonomously seek out the debris and catch it in a net. Designed as a system of CubeSats, each just 10 cm x 10 cm x 10 cm, the trash collector, called OSCaR (Obsolete Spacecraft Capture and Removal), will collect the tiny pieces of junk until it's full and then deorbit itself to burn up in the atmosphere. From RPI:
One of (the three) CubeSat units (in each complete system) will house the “brains” of OSCaR including GPS, data storage, and communication, as well as the power and thermal management systems. Another will hold propellant and the system’s propulsion module to drive OSCaR forward. The third unit will contain four gun barrels, nets, and tethers to physically capture debris, one piece at a time. This capture module will also have optical, thermal, and RADAR imaging sensors to help OSCaR locate debris in the vastness of its surrounding space...
“There’s an informal agreement that’s been in place for a few years that people who put space objects up there should be practicing good citizenship,” (Rensselaer engineering professor Kurt) Anderson said. “We envision a day where we could send up an entire flock, or squadron, of OSCaRs to work jointly going after large collections of debris.”
The Irish Aviation Authority (IAA) is investigating multiple reports of UFOs over the coast of Ireland on Friday. From the BBC:
(A British Airways) pilot, flying from the Canadian city of Montreal to Heathrow, said there was a "very bright light" and the object had come up along the left side of the aircraft before it "rapidly veered to the north..."
(Another Virgin pilot said) there were "multiple objects following the same sort of trajectory" and that they were very bright.
The pilot said he saw "two bright lights" over to the right which climbed away at speed.
One pilot said the speed was "astronomical, it was like Mach 2" - which is twice the speed of sound.
According to the IAA, the matter will be "investigated under the normal confidential occurrence investigation process." Meanwhile, the BBC quotes an astronomer who suggests what the pilots saw could have been a meteoroid aka "shooting star."
Very interesting report on Shannon high level Friday 9 November at 0630z with multiple aircraft with reported sightings of a UFO over County Kerry. Skip to 17 minutes to listen reports on @liveatc https://t.co/VP1p0hrScn #Aviation #UFO #Ireland— Trevor Buckley (@IrishAero) November 11, 2018
During its 1970s heyday, the Concorde, the commercial supersonic plane that did NYC to London in under three hours, wasn't just a revolution in aerospace engineering; it was an icon of industrial design, set the bar in luxury travel, and, quite literally, embodied the jet-set lifestyle. Now, my friend qnd colleague Lawrence Azerrad, the creative director of the Grammy-winning Voyager Golden Record vinyl box set we released last year, has created a glorious art book about the Concorde and its scene in the sky. The book, Supersonic: The Design and Lifestyle of Concorde, overflows with historical and technical information and stunning photos of the plane, its marketing materials, and amenities designed by the likes of Andrée Putman, Raymon Loewy, and Sir Terence Conran who wrote this book's foreword. From CNN:
Taking a branded item home was part of the experience. Anything that could be removed from the plane would be taken by passengers as a souvenir. Some of these items were particularly sought after, like those designed by Raymond Loewy, the father of industrial design who created cabin interiors for Air France.
"He used a very forward-thinking, futuristic approach for that time, down to the design of the seats, the headrests, the fabric and, probably more famously, the stainless steel flatware, which Andy Warhol would famously steal," said Azerrad. "There's a story where (Warhol) asked if the person sitting next to him was taking theirs, she said no and he took her set."
Rolls Royce and Harvard University are exploring how tiny swarm robots could someday crawl through an airplane engine for mechanical check-ups and maintenance.
Each robot measures around 10mm in diameter which would be deposited in the centre of an engine via a ‘snake’ robot and would then perform a visual inspection of hard to reach areas by crawling through the engine. These robots would carry small cameras that provide a live video feed back to the operator allowing them to complete a rapid visual inspection of the engine without having to remove it from the aircraft.
There are more than 500,000 pieces of dangerous space junk orbiting the Earth, not including paint flecks and other tiny bits flying around at 17,500 miles per hour that put spacecraft at risk. The Brane Craft, in the conceptual phase at Aerospace Corporation, is a bulletproof "blanket," one yard across and thinner than a human hair, that the company thinks could wrap around space junk and pull it into the atmosphere where it will safely burn up. The project just received another grant from NASA's Innovative Advanced Concepts program that funds radical concepts that may never work but would have great impact if they do. From Space.com:

The thin spacecraft is not only lightweight, which reduces fuel consumption, but is easy to stack in a launcher and deploy in a swarm of dozens of bots, each on a track to a different rogue piece of debris. Brane Crafts will be powered by ultrathin solar cells as well as a little bit of propellant. The company plans to launch the craft frequently, with many Branes deployed at the same time, helping to reduce costs...
The NIAC grant provides two years of funding for laboratory demonstrations of the thin film. The investigators plan to outline how to develop the technology and which fabrication technologies hold the most promise.
"We're also looking at how we can get government or other companies interested in this to take this to the next level," (Aerospace Corporation principal investigator Siegfried) Janson said, pointing out that readiness for space would likely take a few million dollars.
