>NASA's leading planet-hunting spacecraft has spotted its second planet that matches Earth's size and may be able to retain liquid water — and both worlds orbit the same star.

>NASA's Transiting Exoplanet Survey Satellite (TESS) launched in April 2018; since then, the mission has discovered 285 confirmed exoplanets and more than 6,000 candidates. One of the most intriguing of the confirmed planets is a world dubbed TOI 700 d, which is about the size of Earth and located in its star's habitable zone. Now, scientists have determined that the planet has a neighbor that's just as tantalizing, thanks to an October 2021 alert that the Earth-orbiting telescope had seen something interesting.

>"We first started looking at it and we're like, 'Is this real?'" Emily Gilbert, an astronomer at NASA's Jet Propulsion Laboratory in California, told Space.com. Gilbert and her colleagues are presenting the research at the 241st meeting of the American Astronomical Society, being held this week in Seattle and virtually.

>Why it matters: Police, retail stores, airports and sports arenas are rapidly increasing biometric surveillance. But critics say the results are too often blindly trusted, without enough double-checking of matches.

>Catch up quick: The latest face-recognition surveillance technology is designed to identify people seen on security cameras in real-time, or close to it.

>The minister said that India is constantly making new achievements in the field of science and technology. Science is touching new heights under the leadership of Prime Minister Narendra Modi, which is why India's first self-sufficient Gaganyaan will enter space in 2024.
>
>Giving information about the achievements being made by the government in the field of science and technology, Jitendra Singh said "The idea of taking forward the 'Gaganyaan' program was in 2022 itself but due to Covid-19 it was delayed. In the next year (2024), there will be two preliminary launchings, the first launch will be unmanned, this experiment will be done to mark the routes because if the 'Gaganyaan' rocket goes into space then it should also return safely to the same way."

>"In the other experiment also there will be no human, instead a robot will be there as a human replica. When both the experiments assure that we are completely ready, then in the third one we will send humans into space," the minister added.

>For the first time, scientists were successful at driving at a thousand shots per second a so-called plasma mirror in the relativistic regime, i.e. with a laser field so strong that hurls the plasma electrons back and forth at nearly the speed of light. The feat was accomplished at the LOA (Laboratoire d’Optique Appliquée) in France.
>
>When an intense laser pulse ionizes the surface of a solid target, it creates plasma so dense that it is impenetrable to the laser, even if the target was initially transparent. The laser now gets reflected off this “plasma mirror.” In the relativistic regime, the mirror surface no longer just sits stills but is driven to oscillate so fast that, through a process called relativistic surface high-harmonic generation (SHHG), it temporally compresses the laser’s electromagnetic field cycles. This concentrates the laser energy further in time and makes plasma mirrors a promising path for the generation of ever more intense and shorter laser pulses.

>TECHNOLOGIES ENABLED BY quantum science will help researchers better understand the natural world and harness quantum phenomena to benefit society. They will transform health care, transportation, and communications, and enhance resilience to cyber threats and climate catastrophes. For example, quantum magnetic field sensors will enable functional brain imaging; quantum optical communications will permit encrypted communications; and quantum computers will facilitate the discovery of next-generation materials for photovoltaics and medicines.

>2023 will see more innovation in the design of materials for quantum technologies. Of the many awesome candidates considered so far (e.g., diamonds with nitrogen vacancy defects, van der Waals/2D materials, and high-temperature superconductors), I’m most excited about the use of molecular materials. These materials are designed around carbon-based organic semiconductors, which are an established class of materials for the scalable manufacture of consumer electronics (having revolutionized the multibillion-dollar OLED display industry). We can use chemistry to control their optical and electronic properties, and the infrastructure surrounding their development relies on established expertise.

>It was not a foregone conclusion, as there are some potentially negative environmental factors to mining in space. While it might not cause any immediate harm to ecosystems as it does here on Earth, it does destroy "pristine" environments that have arguably been around since the dawn of the solar system, at least in the case of the asteroids. As excellently portrayed in the Mars trilogy by Kim Stanley Robinson, there will always be a part of humanity that will want to leave space as it is

> However, there are some other confounding factors, including, as the authors point out, that both lunar and asteroid mining are, at this point, highly abstract concepts, the real impact of which may be hard to grok for many study participants. But studies such as this have to start somewhere, and waiting until after there is already a fully-fledged mining mission on the moon to see if it has public support might be a little late. For now, at least, those interested in moving forward with this aspect of the economic development of space have the public on their side.
