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.

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’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.
As their technology is now (granted after the necessary safety tests), they can sell/licence their current development level of technology to NASA to use as artificial gravity generation technology on the International Space Station (as you probably know, the long-term lack of gravity on the ISS is really bad for astronauts’ bodies).

Why is warp drive R&D so important for the future of mankind?
–> Primarily, because without “warp bubble” (warp drive) technology any random object that is “drifting” in space will easily be able to decommission/neutralize even the most robust spacecraft.
–> Without mankind first developing warp drive (“warp bubble”) technology, we will never reach places like Earth 2.0 (presumably in the Proxima Centauri star system).
This is simply because the speeds at which a spacecraft will need to move to get people to another life bearing planet within at least less than half the time of 1 human lifetime’s amount of years, will be way too fast [the relative speed will be way too fast] to allow our spacecraft’s detection systems to anticipate a potential collision with space junk/dust or small meteors. As you know, space junk/dust and small meteors can move at incredibly high relative speeds and at these incredibly high relative speeds even a very small object becomes a serious threat to a spacecraft.
Therefore, any spacecraft traveling at such high relative speeds in space without making use of the protection of a “warp bubble” will be effectively leaving the spaceship vulnerable to these random objects in space to crash into the spaceship. Because, practically it would be virtually impossible for a spaceship to beforehand identify/track and then out-maneuver all of the random objects in space that are going to crash into it while it is traveling between the Solar system and the Proxima Centauri star system – especially if an object is small and traveling at an incredibly high speed.
I trust everyone sees the fundamental need for this technology in order to enable true interstellar (star-to-star) human space exploration.

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

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.

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.
