The future of solar has just got brighter with this ‘ultra-thin’ device for converting stored energy into electricity.
In a remarkable development, the National Aeronautics and Space Administration (NASA) ‘holoported’ the first human being into space late last year. Holoportation is the process through which a three dimensional holographic representation of an individual is created, in a combination of a ‘hologram’ and ‘teleportation’. NASA revealed the development late last week, as it announced that it had transported flight surgeon Dr. Josef Schmid, mixed and virtual reality firm AEXA Aerospance’s chief executive officer Dr. Fernando De La Pena Llaca and others to the International Space Station (ISS) during October 2021 while the ISS was orbiting the Earth at an altitude of 250 miles above the Earth’s surface.

The event place last year when NASA’s Crew 2 astronauts were present on the ISS. The astronauts took to the skies in April last year and returned in November, soon after Dr. Schmid and others were holoportated to the orbiting space laboratory.

The JWST has been gradually cooling down ever since its successful, but the telescope took a major step forward on that front when it its massive 70-foot sunshield at the start of the year. That component allowed JWST’s systems, including its critical Mid-Infrared Instrument (MIRI), to drop to a temperature of approximately minus 298 degrees Fahrenheit (or about minus 183 degrees Celsius).
Getting the JWST to its final operating temperature required NASA and the European Space Agency to activate the telescope’s electric “cryocooler.” That in itself involved passing a technical hurdle dubbed the “pinch point,” or the stage at which the James Webb’s instruments went from minus 433 degrees Fahrenheit to minus 448 Fahrenheit.
“The MIRI cooler team has poured a lot of hard work into developing the procedure for the pinch point,” said Analyn Schneider, MIRI project manager for NASA’s Jet Propulsion Laboratory. “The team was both excited and nervous going into the critical activity. In the end, it was a textbook execution of the procedure, and the cooler performance is even better than expected.”
After launching late last year, NASA’s revolutionary James Webb Space Telescope is finally getting ready to fixate its numerous golden mirrors on distant targets.
Intriguingly, though, one of its 13 early targets isn’t so distant at all — at least in the grand scheme of things. It’ll be looking at Jupiter, the iconic gas giant in our own star system. Of course, we already know quite a bit about the planet already— so why investigate it using the JWST if it can have a closer look at far more distant objects?
“We’ve been there with several spacecraft and have observed the planet with Hubble and many ground-based telescopes at wavelengths across the electromagnetic spectrum (from the UV to meters wavelengths),” Berkeley astronomer Imke de Pater, leader of the Jupiter observation team, told Digital Trends, “so we’ve learned a tremendous amount about Jupiter itself, its atmosphere, interior, and about its moons and rings.”
More than 13 months after the Perseverance rover landed on Mars (on 18 February 2021), the rover’s cameras have finally spotted some of the parts of the Mars 2020 landing system that got the rover safely to the ground.
The parachute and backshell were imaged by Perseverance’s MastCam-Z, seen off in the distance, just south of the rover’s current location. The image was taken on Sol 404, or 6 April 2022 on Earth.

Can robots adapt their own working methods to solve complex tasks? Researchers at Chalmers University of Technology, Sweden, have developed a new form of AI, which, by observing human behavior, can adapt to perform its tasks in a changeable environment. The hope is that robots that can be flexible in this way will be able to work alongside humans to a much greater degree.
“Robots that work in human environments need to be adaptable to the fact that humans are unique, and that we might all solve the same task in a different way. An important area in robot development, therefore, is to teach robots how to work alongside humans in dynamic environments,” says Maximilian Diehl, Doctoral Student at the Department of Electrical Engineering at Chalmers University of Technology and main researcher behind the project.
Types of measurements can be further distinguished by how the sum of the three types of information compares to the information in the quantum state. Whereas optimal measurements preserve the total information in the quantum state, such that it is entirely split between the three types, in non-optimal measurements some information is lost. This lost information can be due to noise in the experiment or inefficient estimates of the original quantum state. Yet sometimes it is inherent in the quantum measurement itself. Such inescapable information loss in non-optimal measurements could give insights into how the classical world appears to emerge from quantum measurements.
Preserving three-way information using photons
In their experimental study, which is published in Physical Review Letters, Seongjin Hong and colleagues at the Korea Institute of Science and Technology and the Korea Institute for Advanced Study showed how the information about a quantum state splits into these three parts. The researchers used photons to experimentally demonstrate information-preserving optimal measurements in which each photon could be in one of three possible states. They then used optical components to perform measurement and reversing operations on the photons, before characterizing their final states and demonstrating the quantitative balance between the three information types.
