Indian-Origin Doctor Anil Menon Among 10 Astronauts Chosen by NASA for Moon Mission

Published

on

Indian-origin physician Anil Menon, a lieutenant colonel at the US Air Force, has been selected by NASA along with nine others to be astronauts for future missions, the American space agency has announced.

Menon, 45, was born and raised in Minneapolis, Minnesota, to Ukrainian and Indian immigrants.
He was SpaceX’s first flight surgeon, helping to launch the company’s first humans to space during NASA’s SpaceX Demo-2 mission and building a medical organisation to support the human system during future missions.

In a statement, NASA announced that it has chosen 10 new astronaut candidates from a field of more than 12,000 applicants to represent the US and work for humanity’s benefit in space.

NASA Administrator Bill Nelson introduced the members of the 2021 astronaut class, the first new class in four years, during a Monday, December 6 event at Ellington Field near NASA’s Johnson Space Center in Houston.

“Today we welcome 10 new explorers, 10 members of the Artemis generation, NASA’s 2021 astronaut candidate class,” Nelson said.

“Alone, each candidate has ‘the right stuff,’ but together they represent the creed of our country: E pluribus unum — out of many, one,” he said.

The astronaut candidates will report for duty at Johnson in January 2022 to begin two years of training.

Astronaut candidate training falls into five major categories: operating and maintaining the International Space Station’s complex systems, training for spacewalks, developing complex robotics skills, safely operating a T-38 training jet, and Russian language skills.

Upon completion, they could be assigned to missions that involve performing research aboard the space station, launching from American soil on spacecraft built by commercial companies, as well as deep space missions to destinations including the Moon on NASA’s Orion spacecraft and Space Launch System rocket.

“Each of you has amazing backgrounds,” Pam Melroy, former NASA astronaut and NASA’s deputy administrator, told the candidates. “You bring diversity in so many forms to our astronaut corps and you stepped up to one of the highest and most exciting forms of public service.”

Applicants included US citizens from all 50 states, the District of Columbia, and US territories Puerto Rico, Guam, the Virgin Islands, and Northern Mariana Islands.

For the first time ever, NASA required candidates to hold a master’s degree in a STEM field and used an online assessment tool. The women and men selected for the new astronaut class represent the diversity of America and the career paths that can lead to a place in America’s astronaut corps.

Menon previously served NASA as the crew flight surgeon for various expeditions taking astronauts to the International Space Station.

He is an actively practicing emergency medicine physician with fellowship training in wilderness and aerospace medicine.

As a physician, he was a first responder during the 2010 earthquake in Haiti, 2015 earthquake in Nepal, and the 2011 Reno Air Show accident.

In the Air Force, Menon supported the 45th Space Wing as a flight surgeon and the 173rd Fighter Wing, where he logged over 100 sorties in the F-15 fighter jet and transported over 100 patients as part of the critical care air transport team.

Aeronautical engineer Sirisha Bandla in July became the third Indian-origin woman to fly into space after Kalpana Chawla and Sunita Williams.

Wing Commander Rakesh Sharma is the only Indian citizen to travel in space. The former Indian Air Force pilot flew aboard Soyuz T-11 on April 3, 1984, part of the Soviet Interkosmos programme.

"Mirror World" Behind One Of Space’s Mysteries: Study

Published

on

A mirror world is a common trope in fantasy and fiction, but it may also be the answer to one of Space’s biggest mysteries today. A group of scientists behind a new research paper suggest that a “mirror world” of particles that remains unseen from us may be the answer to the Hubble Constant problem. The Hubble constant problem refers to the discrepancy in the theoretical value of the rate of expansion in the universe and the actual rate of expansion as observed by measurements. The issue remains to reconcile the two without upending the entire cosmological model as it stands today. As doing so would ruin the agreements with the current scientific models and the observed phenomenon in Space like the cosmic microwave background.

“Basically, we point out that a lot of the observations we do in cosmology have an inherent symmetry under rescaling the universe as a whole. This might provide a way to understand why there appears to be a discrepancy between different measurements of the Universe’s expansion rate,” said lead researchers Francis-Yan Cyr-Racine from the University of New Mexico, and Fei Ge and Lloyd Knox at the University of California.

Their observations were published in the paper titled Symmetry of Cosmological Observables, a Mirror World Dark Sector, and the Hubble Constant, which was released recently in Physical Review Letters.

“The mirror world idea first arose in the 1990s but has not previously been recognised as a potential solution to the Hubble constant problem. This might seem crazy at face value, but such mirror worlds have a large physics literature in a completely different context since they can help solve an important problem in particle physics,” said Cyr-Racine. “Our work allows us to link, for the first time, this large literature to an important problem in cosmology.”

Apart from the mirror world idea, scientists have also considered the possibility of measurement errors to be behind the discrepancy. But as measurement tools have gotten better, the deviation between the theoretical and observed value has only increased, leading many to believe that measurement errors are not the reason behind the discrepancy.

NASA Satellite Captures Unique View of Total Lunar Eclipse That Occurred on May 15

Published

on

A NASA satellite, named Lucy which was launched in October 2021, managed to capture a unique perspective on the total lunar eclipse, which occurred on May 15-16. The satellite was launched for a 12-year journey to probe eight different asteroids, including one asteroid from the main asteroid belt in the solar system. The other seven asteroids that the satellite will probe are from Jupiter’s trojans asteroid cluster.

The satellite was already at a distance of 64 million miles (100 million km) from the Earth, roughly 70 percent of the distance between the Earth and the Sun, when it observed the total lunar eclipse.

“While total lunar eclipses aren’t that rare – they happen every year or so – it isn’t that often that you get a chance to observe them from an entirely new angle,” said planetary scientist Hal Levison of the Southwest Research Institute (SwRI), who is the principal researcher of the mission in a statement.

“When the team realized Lucy had a chance to observe this lunar eclipse as a part of the instrument calibration process, everyone was incredibly excited,” Levison added.

“Capturing these images really was an amazing team effort. The instrument, guidance, navigation and science operations teams all had to work together to collect these data, getting the Earth and the Moon in the same frame,” said Acting Deputy Principal Investigator Dr. John Spencer, also from SwRI.

The satellite took 86 one-millisecond exposure shots in order to make a 2-second timelapse of the first half of the eclipse. The video was published by NASA on its website. People can see a cross-sectional view of the eclipse in the short but mesmerising video.

The video can be found on the following link.

This Battery-Like Device Can Absorb Carbon Dioxide While Charging

Published

on

Researchers at the University of Cambridge have designed a battery-like device that can take us a step further to solve the carbon dioxide emission problems in the present world. This supercapacitor device can selectively absorb CO2 during its charging process. When the battery-like device discharges, it will release the carbon dioxide in a controlled manner in such a way that can be collected to reuse or dispose of it later.

According to an article by EurekAlert, almost 35 billion tonnes of carbon dioxide are released into the atmosphere every year. Hence, the world is in need of urgent solutions to eliminate these emissions to solve the climate change problems.

There have been efforts in this direction, to control, capture, reuse and eliminate carbon emissions from the atmosphere. But the most advanced technologies, in this field, use a lot of energy and are highly expensive. The supercapacitor at the University of Cambridge is designed to capture and store carbon using low-cost technology.

The supercapacitor is as small as a coin. It is partly made using sustainable materials like coconut shells and seawater. Grace Mapstone, the co-author of the study, said, “The best part is that the materials used to make supercapacitors are cheap and abundant. The electrodes are made of carbon, which comes from waste coconut shells.”

Dr Alexander Forse from Cambridge’s Yusuf Hamied Department of Chemistry led the research. He said, “We found that by slowly alternating the current between the plates we can capture double the amount of CO2 than before.” He added, “The charging-discharging process of our supercapacitor potentially uses less energy than the amine heating process used in industry now. Our next questions will involve investigating the precise mechanisms of CO2 capture and improving them. Then it will be a question of scaling up.”

The research, which has been published in the journal Nanoscale, describes the supercapacitor. It uses two electrodes of positive and negative charge. Unlike a rechargeable battery, it does not use chemical reactions to store energy. Instead, it stores energy by the movement of electrons between the electrode plates. This gives it a longer lifespan.

Grace Mapstone said, “We want to use materials that are inert, that don’t harm environments, and that we need to dispose of less frequently. For example, the CO2 dissolves into a water-based electrolyte which is basically seawater.”
