Potential for Microbial Life on Mars

When the Mars Perseverance rover landed on the planet in February, it astonished the world with detailed photos of the planet and audio of the surface. After discovering water and ice on Mars, the next endeavor starting the search for evidence of possible life and life-supporting properties on the planet. A new study conducted by the Astrobiology Journal concluded that there is indeed the right amount of ingredients to support microbial life. The study looked at the planet’s Martian meteorites and their chemical makeup. Observing the chemical reaction whenever these meteorites had continuous constant contact with water once the meteorites fell back to Earth.

Among the many reactions studied, Radiolysis was of massive interest. The reaction is created when radioactive elements like potassium uranium and thorium could be converted sulfates, so much so that they tap water. One of the reasons is that there’s water on the planet because there is a flowing lake somewhere on the planet in the subsurface. It is now believed that once the components of that lake are studied further, how microbial life could exist could possibly be revealed. Also, different wavelengths of light being investigated to potentially give way to a better understanding of Mars’s past.

Further study will be ongoing, but the full extent of the findings may not be known for some time. The idea of life on another planet could be an extraordinary mark left on history forever. We wish all the very best of luck to the teams in their search for answers.

2012 Psychophysics Study Using Optical Slits

               Over the years, science has given us many ways of studying and exploring vast possibilities. One of those miraculous ways is psychophysics, which is defined as the part of psychology the deals with mental phenomena and physical stimulation. Psychophysics works by studying the specifics of physical stimulation and sensation and looking at the responses produced. In psychophysics, three models of study are most used: the method of constant stimuli, the method of limits, and the method of adjustment. The limits method determines the sensory threshold by increasing or decreasing stimulus level gradually. The method of adjustment is, as it sounds, studying the patient’s adjustment to stimulus levels. These are just some examples of what psychophysics can do. Young’s double-slit formula is another physics example using light that studies and displays light particles’ characteristics and defines light waves.

               In a 2012 study, the double-slit experiment was used in about 25 people to record their individual reactions to stimulus. With the initially planned analysis, there was no psychophysical effect found on the subjects. However, as the study notes, there may be causal links found with more detailed analyses. To look at the study more in-depth, please click here.

               At Lenox Laser, we offer various optical products that are probably built in many ways that use the ideas of psychophysics. We have everything from apertures to slits to pinhole photography, gas and liquid separators, particle counters, molecular beam masks, and more. To see our product line, please visit us here and explore our many variations and possibilities.

               It will be interesting to see just how far the evolution of psychophysics will go, along with the uses of Young’s double-slit experiment. Science never stops evolving, and neither should our eagerness to learn all that we can for future endeavors. That curiosity could make the future even brighter.

NASA and Aerosol Jet Printing

Through the years, there have been many different styles of printing, from newspapers on paper presses to photo printing and art design. With these techniques, the amount of ease using them continues to evolve. Aerosol jet printing is a method that allows contactless direct printing for mass manufacturing that uses inkjet technology to put materials on substrates. It is the process of coding a base material used as a foundation for the object or image being printed on material. This process would also aim to significantly reduce printing time and manufacturing costs for companies. Aerosol jet printing can allow fine detail printing of 10 µm for high resolution printing onto different types of hardware and electronics.

The technique is also being used recently by NASA with a combination of 3-D printing that can print electronics such as transistors, conductors, and even cell phone cases. NASA is using it to create motherboards with digital to analog converter chips. If successful, NASA could later use it to mass-produce and print hardware for their many spacecraft.

Non-particle ink such as silver ink would allow extraction of silver non-particles from 10 to 100 µm of extraction. The type of non-particle can also be determined by the metal material used, such as titanium, aluminum, alloy, steel, and more. The difference between inkjet printing and aerosol printing is that aerosol allows 2 to 4 times higher resolution than inkjet, print resolution, and ink viscosity. Aerosol also has a clone-resistant nozzle; inkjet does not; aerosol is more tightly focused on its direction when printing, whereas inkjet is random directionality. Inkjet is a single drop; aerosol can be continuous.

Lenox Laser was able to use our cutting-edge processes in laser drilling flow restrictive orifices to assist in these technological advancements in the field. The full potential of aerosol printing has yet to be realized. However, we at Lenox Laser very helpful for the future and happy to be a part of it.

James Webb Telescope Mirror Packing Update

               The James Webb Space Telescope has taken many years to get to where it is today. It survived complete cancellation in November 2011, infrared systems installation, and other instrument installs in 2012 through 2014. Despite a delay last year due to the ongoing Covid-19 pandemic, the project is still managing to gain momentum toward the finish line. The James Webb Space Telescope is continuing towards its Halloween 2021 launch by hitting the milestone of having its massive protective sunshield folded and packed up to journey into space.

               The telescopes mammoth sunshield will protect the telescopes many optics from the immense heat and light of the sun. Folding the mirrors took one month to complete; they fold up on two sides of the telescope when not in use. The sunshield is about the size of a tennis court when fully deployed and is made up of 18 individual mirrors composed of five layers. Its entire span measures an estimated 70′ x 47′ with a cost of almost $10 billion. Since this telescope has infrared to detect and read heat signatures, the mirrors must be kept extremely cold. Once in space, one side of the mirror will reflect the heat and light from the Earth, Sun, and the Moon, which studies show to be approximately 230°F on the outermost layers. NASA worked with Northrop Grumman to build James Webb into a reality.

               We, at Lenox Laser, designed and provided alignment targets for the infrared systems on James Webb, for which we are most grateful for the opportunity.

Using AI-powered Speakers to Monitor Heart Health

               Artificial intelligence has given the world many advantages over the years, from space travel to smart cars. Its next breakthrough is one of the biggest yet, the human heart. Researchers at the University of Washington have developed a new way to determine health issues with the heart and an utterly contactless manner. The current prototype built by academics at the university would use intelligent speakers to detect heart arrhythmias or irregular heartbeats and high blood pressure. It would be able to do it with almost the same accuracy as devices used in today’s hospitals. The studies and prototypes use things like Amazon Alexa devices, Google Home pods, and smart speakers usually used for music.

               The way the technology works is, the patient would sit a few feet in front of the speaker. Depending on how the pitch and resonance of the sound coming back from the speaker changes, the doctor can determine what the heart issue may be to proceed with the treatment as needed. It would also be able to detect breathing patterns as well. If this works, the National Institute of Health (NIH) would undoubtedly take notice. With this exciting innovation, doctors hope that the new technology will help quickly diagnose patients for years to come even further than the heart, possibly even the brain.

               These recent innovations in medical devices like the one Lenox Laser worked with the NIH in a study about protein sampling and delivery into the brain could help doctors prevent and treat diseases. To all those involved with this new study prototype, Lenox Laser would like to send our best wishes for a profound positive outcome.
