A Lightsail Powered By Millions of Lasers Could Reach Alpha Centauri in 20 Years

Posted by in categories: innovation, space

Breakthrough Starshot’s ultra-lightweight spacecraft will have to travel four light-years to reach Alpha Centauri. To put it another way, our nearest neighboring star system is a mind-shattering 40,208,000,000,000 (40 trillion) km away from Earth.

As a point of reference, our fastest and most reliable technology today for long-range space travel is the ion thruster, which is powering NASA’s DART mission to a nearby asteroid at speeds of 15,000 mph (24,000 km/h). However, according to NASA, with the ion thruster, it would take 18,000 years, or approximately 2,700 human generations, to get to Alpha Centauri.

NASA introduces the new astronaut class of 2021

Posted by in category: space

Ten men and women are ready to begin training so they can journey to the International Space Station, the moon and beyond. The new astronaut class of 2021 was announced by NASA on Monday.

The 10 astronaut candidates, the first new astronaut class in four years, were selected from more than 12,000 applicants. The agency’s administrator, Bill Nelson, introduced them live from Ellington Field near NASA’s Johnson Space Center in Houston, where the candidates will spend the majority of the next two years training beginning in January 2022.

“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.”

A Ten-Minute Run Can Boost Brain Processing

Posted by in categories: biotech/medical, neuroscience

Summary: A ten-minute run increases activation of the bilateral prefrontal cortex, improving mood and cognitive function.

Source: University of Tsukuba

Running may be a useful activity to undertake for better mental health. University of Tsukuba researchers have found that only ten minutes of moderate-intensity running increases local blood flow to the various loci in the bilateral prefrontal cortex —the part of the brain that plays an important role in controlling mood and executive functions.

Building Skills-Friendly Cities To Prepare For The Future Of Work

Posted by in categories: business, education, employment, government, robotics/AI

Skills shortages are easily brushed off as Covid collateral, but in fact, they are much more troubling signs of an education system that is not preparing people for the future of work. These issues stem from a union of education and employment that has been designed to fill specific criteria for the workforce, but the job market that young people are training for today will require a much greater emphasis on human skills to complement the repetitive tasks handled by AI and automation.

But bringing up young people with the human skills they need for a changing world of work is a mammoth task that must combine the powers of government, businesses, and dedicated organizations to reshape our education systems and integrate them with the communities they serve. I spoke with Justin van Fleet, Executive Director of the Global Business Coalition for Education (GBC-Education), about the need for a holistic and skills-centered approach to education, and how change needs to start as early as possible.

Model Mars Rover Does A Zombie Walk To Escape A Sand Trap

Posted by in categories: futurism, space

This rover has moves that could take over a dance floor. A new video shows a simulator known as the Ground Test Model doing a sort of zombie walk over Martian-like terrain, to test out techniques for a future Mars missions.

“The rover initially has its front two wheels almost completely buried in sand, but easily escapes using its unique wheel-walking mode,” the European Space Agency said in a statement of the testing at Thales Alenia Space facilities in Turin, Italy, noting that the 6-foot drive took about 20 minutes to accomplish.

“The back wheels drag once the front four wheels have gained good traction on firmer terrain. The reason is that the wheel-walking sequence tested here has rather been optimized for climbing steep slopes with loose soils,” ESA added of the sequence.
