John Glenn, first American to orbit the Earth, dies at 95
Posted by Blair Erickson in categories: biotech/medical, military, space
John Glenn, who captured the nation’s attention in 1962 as the first American to orbit the Earth during a tense time when the United States sought supremacy over the Soviet Union in the space race, and who rocketed back into space 36 years later, becoming the oldest astronaut in history, died Dec. 8 at a hospital in Columbus, Ohio. Mr. Glenn, who in his post-NASA career served four terms as a U.S. senator from Ohio, was 95.
The death was confirmed by Hank Wilson, communications director at the John Glenn College of Public Affairs at Ohio State University. Mr. Glenn had a stroke after heart-valve replacement surgery in 2014, but the immediate cause was not announced.
Mr. Glenn was one of the seven original astronauts in NASA’s Mercury program, which was a conspicuous symbol of the country’s military and technological might at the height of the Cold War. He was not the first American in space — two of his fellow astronauts preceded him — but his three-orbit circumnavigation of the globe captured the imagination of his countrymen like few events before or since. Mr. Glenn was the last survivor of the Mercury Seven.

Vision of a Asteroid Belt Astronomical Telescope and hypertelescopes
Posted by Klaus Baldauf in categories: physics, space
Physics Today has a speculative article that proposes that laser light be used to shape and polish an asteroid to high optical standards. This could create an Asteroid Belt Astronomical Telescope (ABAT).
The Asteroid Belt Astronomical Telescope (ABAT) focuses light from laser-polished asteroids onto dual imaging arrays above and below the solar system; other intense laser pulses maneuver the arrays to different locations, thus allowing ABAT to point at multiple celestial targets. Asteroid ablation residue corralled into a pair of Devil’s Footprints shields the focal regions from solar illumination. (Courtesy of Laura Kim.)

Space Warp Dynamics: The startup that’s working on sending humans to Proxima Centauri
Posted by Johan Scholtz in categories: physics, science, space, space travel
Space Warp Dynamics’s mission is fundamentally an audacious endeavor in terms of what we deem as the status quo of spacecraft propulsion and in terms of where humanity will be able to reach in the galaxy (other stars) within the next 15–20 years (and not only within the next 200+ years from now). In other words, if this challenge can be addressed with the appropriate resources and the right people’s support, then for example you and your family will potentially be able to travel to Earth 2.0 (presumably in the Proxima Centauri star system).
Space Warp Dynamics can already currently demonstrate (prove) that their invention can manipulate (warp or bend) space-time in a controlled micro-environment. This could mean that we finally know how gravity works and also how to control gravity and this in itself is a monumental accomplishment.

Cannae will try to prove propellentless propulsion in space in 2017 and has ambitious space probe designs with 33 years of constant acceleration to reach 3% of lightspeed
Posted by Klaus Baldauf in category: space
Despite having a setup that has been pretty much operating for years, how many data points are in the paper? Eighteen. Now, if this were a really time-consuming experiment, I wouldn’t let that bother me. Hell, some synchrotron experiments have only a single data point. But this is clearly not a time-limited experiment.

The Dawn of AI: Congress Is Discussing What We’ll Do in a World Run by Robots
Posted by Elmar Arunov in categories: government, robotics/AI, space
In Brief
- Last week’s US Senate Subcommittee on Space, Science, and Competitiveness focused on the impact AI has in various sectors of US society.
- Scientists predict that investments in AI will increase by more than 300 percent over the next few years, meaning AI will have a more prominent role in society.
Senator Ted Cruz opened up last Wednesday’s hearing by the US Senate Subcommittee on Space, Science, and Competitiveness with a description of the changing landscape of technology: “Whether we recognize it or not, artificial intelligence is already seeping into our daily lives.”
Senator Cruz explained that scientists are predicting how investments in AI will increase by more than 300 percent in the next few years, which means AI will have a more prominent role in society. With that in mind, the subcommittee’s hearing focused on the impact AI has in various sectors of US society, and how to best ensure US leadership in AI development.

Scientists have finally figured out why astronauts lose their vision while in space
Posted by Jeremy Lichtman in categories: neuroscience, space
Radiologists have finally figured out why astronauts who spend a lot of time in space get impaired vision.
The problem, called visual impairment intracranial pressure (VIIP) syndrome, has been reported in two-thirds of astronauts who go up to the International Space Station.
And according to a new study from researchers at the University of Miami — reported Monday at the Radiological Society of North America’s annual conference — those changes to the eye have everything to do with changes in the fluid that surrounds the brain and spinal cord.
