NASA Confirms What They Suspected About Jezero Crater on Mars All Along Images from Mars reveal how water helped shape the Red Planet's landscape billions of years ago, and provide clues that will guide the search for evidence of ancient life, a study said Thursday. In February, NASA's Perseverance rover l anded in Jezero crater , where scientists suspected a long-gone river once fed a lake, depositing sediment in a fan-shaped delta visible from space. The study in Science analyzed high-resolution images captured by Perseverance of the cliffs that were once the banks of the delta. Layers within the cliffs reveal how its formation took place. NASA astrobiologist Amy Williams and her team in Florida found similarities between features of the cliffs seen from the crater floor and patterns in Earth's river deltas. The shape of the bottom three layers showed a presence and steady flow of water early on, indicating Mars was "warm and humid enough to support a hydrologic cycle" about 3.7 billion years ago, the study says. Mastcam-Z enhanced color mosaic shows a butte near Jezero crater dubbed "Kodiak". (NASA/JPL-Caltech/LANL/CNES/CNRS/ASU/MSSS) The top and most recent layers feature boulders measuring more than a meter in diameter scattered about, probably carried there by violent flooding. But it is the fine-grained sediment of the base layer that will likely be the target of sampling for signs of long-extinct life – if it existed – on Mars. The findings will help researchers figure out where to send the rover for soil and rocks that may contain precious "biosignatures" of putative Martian life forms. "From orbital images, we knew it had to be water that formed the delta," Williams said in a press release. "But having these images is like reading a book instead of just looking at the cover." Finding out whether life may have existed on Mars is the main mission of Perseverance, a project that took decades and cost billions of dollars to develop. Over the course of several years, the multi-tasking rover will collect 30 rock and soil samples in sealed tubes, to be eventually sent back to Earth sometime in the 2030s for lab analysis. Last month, mission scientists announced Perseverance had collected two rock samples in Jezero that showed signs they were in contact with groundwater for a long period. Their hope is that the samples might at one point have hosted ancient microbial life, evidence of which could have been trapped by salt minerals. Learning that Mars might once have harbored life would be one of the most "profound" discoveries ever made by humanity, Williams said. She also expressed wonder at having a window onto an ancient river system on another planet.https://www.sciencealert.com/the-jezero-crater-on-mars-was-once-a-huge-lake-images-from-perseverance-confirm

The effects of particles on clouds are temporary and localized, so experiments on MCB could be carried out over small areas and brief time periods (maybe spraying for a few hours per day over several weeks or months) without seriously perturbing the environment or global climate. These small studies would still yield significant information on the impacts of brightening. What's more, we can quickly halt the use of MCB, with very rapid cessation of its effects. Solar climate intervention is the umbrella term for projects that involve reflecting sunlight to reduce global warming and its most dangerous impacts. Our project encompasses three critical areas of research. First, we need to find out if we can reliably and predictably increase reflectivity. To this end, we'll need to quantify how the addition of generated sea salt particles changes the number of droplets in these clouds, and study how clouds behave when they have more droplets. Depending on atmospheric conditions, MCB could affect things like cloud droplet evaporation rate, the likelihood of precipitation, and cloud lifetime. Quantifying such effects will require both simulations and field experiments.https://spectrum.ieee.org/q-a-with-co-creator-of-the-6502-processor

It is true that one of the major benefits of self-driving vehicles will be the safety factor, as it is thought that 90% of all traffic accidents are the result of human error. By eliminating the human factor, mobility will, in fact, be safer and more efficient. As it can be seen above, all factors above have a common goal: safety. AV will make roads safer, but it can only be accomplished if all parts of the AV and its environment work in perfect how you can help order. Vehicle manufactures which are working on the development of AV are mostly focusing on the close surroundings of the vehicle by installing on board devices, such as lidars, radars or cameras that automatically collect information around the vehicle. However, a wider scope of information beyond the immediate surroundings has to be taken into consideration, as well. This information is incredibly useful and necessary to create safer, high-capacity, high-performance, more efficient, less congested, and less polluted roads. In order for AV to collect this wider scope of information, roads have to be enhanced by including highly visible, highly reflective road markers or barriers that ensure the best performance for these AV. At Ferrovial, we are working in this direction and investing in the success of autonomous mobility by cross-industry collaboration through the AIVIA Connected Corridors Project for US highways, which will increase road safety for users and facilitate safe interaction between autonomous and conventional vehicles in high-density and high-speed urban corridors. The result will be the reduction of travel time and congestion while offering a 5G broadband network along these highways. Moreover, AIVIA will even offer infotainment for drivers using our infrastructure, for a more enjoyable journey, especially when the vehicle is driving for you! When it comes to autonomous mobility, bonuses the possibilities are endless, but that doesn't mean that everyone is fully onboard. Understandably, as with any new technological advancements, there is always a fair share of skepticism and fear, and maybe even more so with something many of us have only seen on TV. However, autonomous mobility should be something we are looking forward to, not something feared. It will revolutionize the way we move around our world. Not only by making mobility faster and more efficient, but also making it safer.https://www.marketscreener.com/quote/stock/FERROVIAL-S-A-70599/news/Connected-Automated-Vehicles-CAVs-The-Road-Ahead-36634651/
Quality Management Systems Essential to Many Industries and Services Quality management systems (QMS) have been in place since the beginning of the Industrial Revolution. Early quality controls systems were used to manage and curtail defects in the products and eventually evolved to become a set of standards that controlled both the product and production processes. As more workers and companies had to work together to produce acceptable results and production quantities grew, best practices were needed to ensure that quality goods were consistently produced. These best practices for controlling product and production processes were established and documented, and these turned into standard practices for quality management systems. As manufacturing and production lines became more automated and accelerated in the 1950s and ‘60s, and production rates increased rapidly, quality became even more important because the potential of large quantities of sub-standard products entering the market became a reality. Producing quality products became more than having a quality control system in place to discover defects and make transactional corrective actions. Quality control (QC) systems eventually gave way to quality assurance (QA) systems when manufacturers began to understand that quality products had to have quality built into the production process, and not just a QC system that discovered defects in an end item inspection and scrapped bad parts. The premise of QA was based on the research and early work of American manufacturing thinkers like Joseph Juran and W. Edwards Deming. They based QA on methods like statistical process control (SPC), a method which employs statistical data and information to monitor and control the overall production process, thus ensuring that the production process will produce quality products.https://www.arcweb.com/industry-best-practices/quality-management-systems-essential-many-industries-services
