Flying at Speeds up to Mach 17 Could Become Reality

Posted by in categories: military, space travel

University of Central Florida researchers are building on their technology that could pave the way for hypersonic flight, such as travel from New York to Los Angeles in under 30 minutes.

In their latest research published Monday in the journal Proceedings of the National Academy of Sciences, the researchers discovered a way to stabilize the detonation needed for hypersonic propulsion by creating a special hypersonic reaction chamber for jet engines.


The UCF-developed propulsion system could allow for flight speeds of Mach 6 to 17 and would have applications in air and space travel.

We Don’t Need To Go To Mars

Posted by in category: space travel

Buckle up, this one is fun: Maciej Cegowski has begun what promises to be a multi-part essay arguing against a crewed mission to Mars. It’s called “Why Not Mars,” it’s 8,000 words long, with 66 footnotes, and it sings. I’m not even sure I agree, but I enjoy the hell out of it.

The goal of this essay is to persuade you that we shouldnt send human beings to Mars, at least not anytime soon. Landing on Mars with existing technology would be a destructive, wasteful stunt whose only legacy would be to ruin the greatest natural history experiment in the Solar System. It would no more open a new era of spaceflight than a Phoenician sailor crossing the Atlantic in 500 B.C. would have opened up the New World. And it wouldnt even be that much fun.

A few choice lines:

The space between Earth and the moon is about to get a little more crowded

Posted by in category: space travel

With multiple nations and private companies now setting their sights on missions to the moon, experts say cislunar space — the area between Earth and the moon — could become strategically important, potentially opening up competition over resources and positioning, and even sparking geopolitical conflicts.

The Dark Side of Artificial Intelligence: Dystopian Future Inevitable?

Posted by in categories: robotics/AI, space travel

As technology continues to advance at an exponential rate, it’s hard to ignore the nagging feeling that we may be heading toward a dystopian future. In this video, we’ll be examining the potential dangers of artificial intelligence and machine learning; how they could lead us down a dark path if left unchecked. From the displacement of human workers to the loss of privacy and control, the repercussions of our reliance on technology are far-reaching and potentially disastrous.

Rotating Detonation Rocket Engine: NASA’s Revolutionary Propulsion Design for Deep Space Missions

Posted by in category: space travel

NASA takes its first steps toward establishing a long-term presence on the Moon’s surface, a team of propulsion development engineers at NASA have developed and tested NASA’s first full-scale rotating detonation rocket engine, or RDRE, an advanced rocket engine design that could significantly change how future propulsion systems are built.

The RDRE differs from a traditional rocket engine by generating thrust using a supersonic combustion phenomenon known as a detonation. This design produces more power while using less fuel than today’s propulsion systems and has the potential to power both human landers and interplanetary vehicles to deep space destinations, such as the Moon and Mars.
