Automated Technology Allows Unparalleled Space Exploration from Moon, to Asteroids, and Beyond

Posted by in categories: mapping, security, space

When landing Apollo 11 in 1969, astronauts looked out the window for distinguishing features that they recognized from maps of the Moon and were able to steer the lander to avoid a disastrous touchdown on top of a rocky area. Now, 50 years later, the process can be automated. Distinguishing features, like known craters, boulders, or other unique surface characteristics, provide insight into surface hazards to help avoid them while landing.

NASA scientists and engineers are maturing technology for navigating and landing on planetary bodies by analyzing images during descent – a process called terrain relative navigation (TRN). This optical navigation technology is included on NASA’s newest Mars rover, Perseverance, which will test TRN when it lands on the Red Planet in 2021, paving the way for future crewed missions to the Moon and beyond. TRN was also being used during NASA’s recent Origins, Spectral Interpretation, Resources Identification, Security, Regolith Explorer (OSIRIS-REx) mission Touch-and-Go (TAG) event to collect samples of the asteroid Bennu in order to better understand the characteristics and movement of asteroids.

Since reaching Bennu in 2018, the OSIRIS-REx spacecraft has mapped and studied its surface, including its topography and lighting conditions, in preparation for TAG. Nightingale crater was chosen from four candidate sites based on its great amount of sampleable material and accessibility for the spacecraft.

In New Milestone, Physicists Store And Transport Light Using Quantum Memory

Posted by in categories: computing, internet, mapping, particle physics, quantum physics, security

We stored the light by putting it in a suitcase so to speak, only that in our case the suitcase was made of a cloud of cold atoms,” says physicist Patrick Windpassinger from Mainz University in Germany. “We moved this suitcase over a short distance and then took the light out again.


The storage and transfer of information is a fundamental part of any computing system, and quantum computing systems are no different – if we’re going to benefit from the speed and security of quantum computers and a quantum internet, then we need to figure out how to shift quantum data around.

One of the ways scientists are approaching this is through optical quantum memory, or using light to store data as maps of particle states, and a new study reports on what researchers are calling a milestone in the field: the successful storage and transfer of light using quantum memory.

New Chrome 0-day Under Active Attacks – Update Your Browser Now

Posted by in categories: computing, security

Attention readers, if you are using Google Chrome browser on your Windows, Mac, or Linux computers, you need to update your web browsing software immediately to the latest version Google released earlier today.

Google released Chrome version 86.0.4240.111 today to patch several security high-severity issues, including a zero-day vulnerability that has been exploited in the wild by attackers to hijack targeted computers.

Tracked as CVE-2020–15999, the actively exploited vulnerability is a type of memory-corruption flaw called heap buffer overflow in Freetype, a popular open source software development library for rendering fonts that comes packaged with Chrome.

‘Classified knots’: Researchers create optical framed knots to encode information

Posted by in categories: encryption, quantum physics, security

In a world first, researchers from the University of Ottawa in collaboration with Israeli scientists have been able to create optical framed knots in the laboratory that could potentially be applied in modern technologies. Their work opens the door to new methods of distributing secret cryptographic keys—used to encrypt and decrypt data, ensure secure communication and protect private information. The group recently published their findings in Nature Communications.

“This is fundamentally important, in particular from a topology-focused perspective, since framed knots provide a platform for topological quantum computations,” explained senior author, Professor Ebrahim Karimi, Canada Research Chair in Structured Light at the University of Ottawa.

“In addition, we used these non-trivial optical structures as information carriers and developed a security protocol for classical communication where information is encoded within these framed knots.”

New Neutron Detector Can Fit in Your Pocket – Critical for Catching Smuggled Nuclear Materials

Posted by in categories: materials, security

Homeland Security might soon have a new tool to add to its arsenal.

Researchers at Northwestern University and Argonne National Laboratory have developed a new material that opens doors for a new class of neutron detectors.

With the ability to sense smuggled nuclear materials, highly efficient neutron detectors are critical for national security. Currently, there are two classes of detectors which either use helium gas or flashes of light. These detectors are very large — sometimes the size of a wall.

Australlite: There have been lots of posts about SpaceX StarLink starting services in Australia

Posted by in categories: education, food, government, health, internet, satellites, security

In 2016, I proposed LEO HTS Mega Constellation a viable solution for Australia’s broadband national coverage. I have been doing research on these constellations right from the beginning and they are inevitable!


Introduction

Utilizing the announced Lower Earth Orbit (LEO) satellites constellations of OneWeb, SpaceX, LeoSat & Samsung to provide high speed connectivity to entire Australian continent with performance better than fiber networks. This project can eliminate high cost NBN roll out to scattered populations and will considerably improve disaster management. Providing high speed connectivity for mobile communication, internet, high resolution TV broadcast as well as utilizing technologies like IoT & Cloud for improvement in security, education, health, agriculture, livestock farming, mineral resources, wildlife, and environment without any coverage black-spots. This network will not require any infrastructure installations and will help the Government to generate revenues by issuing spectrum licenses to local as well as foreign investors for providing services directly to the end user.

Home security cams hacked in Singapore, and stolen footage sold on adult websites

Posted by in categories: food, habitats, internet, security

* Unsecured home security cameras hijacked * Stolen images circulate on Discord * Everyone needs to take IoT security more seriously.

In Singapore it’s not at all uncommon today for people to have IP cameras all over their homes.

And, of course, the more people who installed internet-connected cameras throughout their private residences the more you would be considered odd if you hadn’t jumped on the bandwagon, and put cameras in your living room, kitchen, bedroom, sometimes even with a view of even more private areas of your house.
