We’re building thermonuclear spaceships again—this time for real

“Phoebus 2A, the most powerful space nuclear reactor ever made, was fired up at Nevada Test Site on June 26, 1968. The test lasted 750 seconds and confirmed it could carry first humans to Mars. But Phoebus 2A did not take anyone to Mars. It was too large, it cost too much, and it didn’t mesh with Nixon’s idea that we had no business going anywhere further than low-Earth orbit.

But it wasn’t NASA that first called for rockets with nuclear engines. It was the military that wanted to use them for intercontinental ballistic missiles. And now, the military wants them again.” (Ars Technica)

Inbrain Neuroelectronics has produced a novel brain implant made of graphene and is gearing up for its first in-human test this summer. The technology is a type of brain-computer interface. BCIs have garnered interest because they record signals from the brain and transmit them to a computer for analysis. They have been used for medical diagnostics, as communication devices for people who can’t speak, and to control external equipment, including robotic limbs. However, Inbrain intends to transform its BCI technology into a therapeutic tool for patients with neurological issues such as Parkinson’s disease. (via IEEE Spectrum)
