The tech-industry is led by sci-fi nerds who want to create the things they read about, or saw on screen.
We all stand to benefit, provided that is, they can avoid the ethical pitfalls depicted in science fiction.

T he world’s most advanced litter-picker will be launched into space next week to clean up floating debris which is threatening satellites and the International Space Station (ISS).
Surrey University has designed a spacecraft which can grab space junk then pull it into Earth’s atmosphere where it is burned up.
The little craft, named RemoveDebris, is due to launch from the Kennedy Space Centre on Monday, on board one of Elon Musk’s SpaceX Falcon 9 rockets.

A one-way trip to Mars with conventional chemical rockets could take up to nine months. It’s a long time for humans to be in a spaceship exposed to radiation and other hazards. That’s one reason NASA, space agencies, universities, and private industry are pursuing different rocket technologies. Here’s a look at them.
Many asteroids are rich in minerals, metals and water, making them potential life support systems for humans venturing deep into the solar system.
“Asteroids contain all the materials necessary to enable human activity,” says Peter Stibrany, chief business developer and strategist of California-based Deep Space Industries (DSI). “Just those near Earth could sustain more than 10bn people.”
Moreover, their relatively small mass means their gravitational field is weak, so in this respect, at least, they are much easier than larger bodies such as the moon to land on and leave, he argues.
Out of billions of stars in the Milky Way galaxy, there’s one in particular, orbiting 25,000 light-years from the galactic core, that affects Earth day by day, moment by moment. That star, of course, is the sun. While the sun’s activity cycle has been tracked for about two and a half centuries, the use of space-based telescopes offers a new and unique perspective of our nearest star.
The Solar and Heliospheric Observatory (SOHO), a collaboration between NASA and the European Space Agency (ESA), has been in space for more than 22 years — the average length of one completed solar magnetic cycle, according to an image caption from ESA. In the new image, SOHO researchers pulled together 22 images of the sun, taken each spring over the course of a full solar cycle. When the sun is at its most active, strong magnetic fields show up as bright spots in the sun’s outer atmosphere, called the corona; black sunspots appear as concentrations of magnetic fields reduce the sun’s surface temperature during active periods as well.
Throughout the sun’s magnetic cycles, the polarity of the sun’s magnetic field gradually flips. This initial phase takes 11 years, and after another 11 years, the magnetic field’s orientation returns to where it began. Monitoring the entire 22-year cycle provided significant data regarding the interaction between the sun’s activity and Earth, improved space-weather forecasting capabilities and more, ESA officials said in the caption. SOHO has revealed much about the sun itself, capturing “sunquakes,” discovering waves traveling through the corona and collecting details about the charged particles it propels into space, called the solar wind.

Humanity’s brutal and bellicose past provides ample justification for pursuing settlements on the moon and Mars, Elon Musk says.
The billionaire entrepreneur has long stressed that he founded SpaceX in 2002 primarily to help make humanity a multiplanet species — a giant leap that would render us much less vulnerable to extinction.
Human civilization faces many grave threats over the long haul, from asteroid strikes and climate change to artificial intelligence run amok, Musk has said over the years. And he recently highlighted our well-documented inability to get along with each other as another frightening factor. [The BFR: SpaceX’s Mars Colony Plan in Images].
Toyota is developing a device that would allow objects to turn invisible, or at least transparent. The Japanese car maker recently received a patent from the U.S. Patent and Trademark Office for a device meant to improve the visibility of drivers.
From cloaking devices that conceal spaceships, to Harry Potter’s hand-me-down disappearing blanket, or even the One Ring and its power to conceal its wearer, invisibility is a staple in science fiction and fiction in general. Scientists have been hard at work, however, to bring such a technology into reality. Joining the research and development of cloaking technology is Japanese car manufacturer Toyota.
Space has suddenly become big in New Zealand, but Rocket Lab is just one example of what is starting to look like exponential growth in commercial activity. Business consultant and self-confessed space junkie Kevin Jenkins looks into how things are shaping up.
One space narrative is about disappointment. The 1950s and 1960s were about possibilities, and landing on the Moon seemed to prove that the science fiction of the 20th century really was just history written before it happened. But the promise of space seemed to peter out. The Apollo moon programme came to look more like a peak or end-point, rather than the trial run for Mars some in the space programme had hoped it would be.
After Apollo, “space” seemed to shift back to being more of a popular culture theme. For example, the famous song, album and movie Space is the Place is by one of my favourite jazz weirdos, Sun Ra, who was adamant he came from Saturn. Space became a dominant meme in pop and rock music too, as well as a mainstay in novels and films.
