Could a stingray-shaped spacecraft get to the dark side of Venus by flapping its wings?

Researchers at the University of Buffalo (UB) are designing a spacecraft shaped like a stingray that could explore Venus in ways never before possible. The craft, designed as part of the Bio-inspired Ray for Extreme Environments and Zonal Explorations (BREEZE) project, is one of 12 selected by NASA for the agency’s Innovative Advanced Concepts (NIAC) program, which supports new, innovative technologies.

Elon Musk has revealed the official launch date for Tesla’s “Cyberpunk” Pickup Truck. According to the CEO, the upcoming vehicle would be released on November 21, 2019 at the SpaceX rocket factory in Hawthorne, CA.

Musk’s update formally ends a period of speculations that have long swept the electric car community with regards to the unveiling of the Tesla Pickup Truck. The CEO, after all, has praised the vehicle as one of his personal favorites. Yet, despite this, Tesla has been able to keep details of the Cybertruck secret, with zero sightings or spy shots of the vehicle to date.

The second objective is propulsion. This is achieved by emitting pulsed cathode rays out of one end of the craft tuned to the rate of change of jet stream particles surrounding the bubble. At the other end of the craft, cations are emitted at the same rate of change. This creates a push/pull effect, doubling the ship’s acceleration and velocity capabilities.

Mark H. says he was abducted by aliens. He clearly remembers awakening one night, unable to move anything but his eyes. He saw flashing lights, heard buzzing sounds, experienced feelings of levitation, and felt electric tingling sensations. Most terrifying were the nonhuman figures he saw by his bed.

Mark believes they were aliens.

Later, he underwent hypnosis to try to recall exactly what had happened to him. Under hypnosis, Mark remembered being whisked through an open window to a large spaceship. He was very frightened when aliens took him into some kind of medical examining room. There he had sex with one of them.

“There are a number of critical technologies that have to be assessed and tested before we go to Mars,” he told Quirks & Quarks host Bob McDonald.

His short-list includes reusable landers, new space suits, mining gear, water and fuel production plants and safe nuclear power sources that could be used to power habitats and equipment on the red planet.

Thirsk himself is currently working with the Canadian Space Agency to investigate the unique biomedical and health care issues involved in long term deep space missions.

Sean Carroll is a theoretical physicist at Caltech and Santa Fe Institute specializing in quantum mechanics, arrow of time, cosmology, and gravitation. He is the author of several popular books including his latest on quantum mechanics (Something Deeply Hidden) and is a host of a great podcast called Mindscape. This conversation is part of the Artificial Intelligence podcast.

This is the second time Sean has been on the podcast. You can watch the first time here: https://www.youtube.com/watch?v=l-NJrvyRo0c
