Next, the technology maturation process, unfolds in a linear fashion with the ultimate objective of transitioning to the NASA program that established the requirement. This process sacrifices science and the ability to iterate fast; does not incentivize providers to develop affordable and systematic capabilities, and the consideration of economic intelligence and market pull is anything but strategic (engagement model with industry is secondary, i.e “work for hire” contracts, and commercialization is serendipitous). As the sole customer, NASA/the government needs to maintain the unique infrastructure needed for these missions and maintains large per mission costs.

While science missions are largely competitive and outcome focused, human missions start by establishing a destination — the political choice of Moon or Mars — often becoming a solution in search of a problem. Since the Apollo era, the overall result of this “swing” approach has basically resulted in “grounding” the human space program, negatively affecting the morale of the working force, and making many feel that it is little more than a job welfare program.

From an HR perspective, NASA, like any other government organization, is a great example of Peter’s principle, structured and incentivized by the slogan “the hierarchy needs to be preserved by all costs”, frequently leading to the alienation or outright removal of highly competent people focused on problem solving and with a desire of seeing accelerated progress.

Despite being battered by Hurricane Maria, and facing a decrease in funding from the U.S. government, the Arecibo radio telescope in Puerto Rico is still going strong, and is now up and running again, following a series of repairs. And with the near-Earth asteroid 3200 Phaethon having just flown by our planet, Arecibo has just sent back images that are supposed to represent the highest-resolution photos of the asteroid, which help reveal some important details about the object.

According to a press release from NASA, the radar images were taken by the Arecibo Observatory Planet Radar last Saturday, December 16, and generated the day after, as asteroid Phaethon 3200 had its close encounter with Earth. At the time of its closest approach, the object was only 1.1 million miles away from Earth, or less than five times the distance separating our planet from the moon. The images have resolutions estimated at about 250 feet per pixel, making them the best-quality photos of the asteroid that are currently available, Phys.org added.

Based on Arecibo’s radar images, scientists believe that 3200 Phaethon is substantially larger than once estimated, with a diameter of approximately 3.6 miles, or 0.6 miles larger than what previous studies had suggested. That also makes Phaethon the second largest near-Earth object classified as a “potentially hazardous asteroid,” or a comparatively large asteroid that orbits much closer to Earth than most others do. The images also suggest Phaethon has a spheroidal shape, with a number of peculiar physical features that scientists are still trying to understand in full. These features include a concave area believed to be several hundred meters wide, and a dark, crater-like area located near one of its poles.

Although solar panels might appear bright and shiny, in desert environments, where they are most frequently installed, layers of dust and other particles can quickly coat their surface. These coatings can affect the panels’ ability to absorb sunlight and drastically reduce the conversion of the sun’s rays into energy, making it necessary to periodically wash the panels with water. But often, in areas like Nevada, water resources are scarce.

Consequently, NEXUS scientists have turned their attention toward developing technologies for waterless cleaning. NASA has already been using such techniques to wash panels in the lunar and Mars missions, but their developed methodologies prove too expensive for widespread public application. NEXUS scientist Biswajit Das of UNLV and his team are aiming to develop a water-free cleaning technology that will be cost-effective for large-scale photovoltaic generation, whereby they look to nanotechnology, rather than water, to clean the panels. “Our mission is to develop a waterless, or at least a less-water cleaning technique to address the effect of dust on solar panels,” Das says. “Once developed, this method will significantly reduce water use for the future PV generation.”

A new technique for recording image information onto a surface creates the ability for one space to contain multiple holographic snapshots, depending on how you look at it.

With this new research, cramming numerous holograms without loss of resolution on the same material could open the way to some fascinating new applications.

Holograms have been around for over half a century, serving as art, entertainment, and foils to counterfeiting. It’s been a hard and fast rule that no matter which way you view a hologram, the same object would appear in three dimensions. Until now.
