Elon Musk, CEO of Space Exploration Technologies (SpaceX) and Tesla Motors, Inc, was at Startmeup Hong Kong and talked about what he thought were areas of technological opportunity.

At 37 minutes into this video Elon Musk talks about high potential technology like Hyperloop which he currently does not have time to address electric aircraftgenetics is thorny but is our best shot at many tough diseasesbrain computer interfaces at the neuron level has potential for intelligence augmentationNeural Lace was mentioned.

Scientists from China and the US have found a pioneering way to inject a tiny electronic mesh sensor into the brain that fully integrates with cerebral matter and enables computers to monitor brain activity.

Researchers from Harvard and the National Center for Nanoscience and Technology in Beijing have succeeded in inventing a flexible electrical circuit that fits inside a 0.1mm-diameter glass syringe in a water-based solution.

This tiny electronic mesh sensor is thin and flexible enough to be injected into the brain and gentle enough to integrate fully with brain cells, making human cyborgs a possibilityLieber Research Group, Harvard University

When injected into the brains of mice, the mesh unfurled to 30 times its size and mouse brain cells grew around the mesh, forming connections with the wires in the flexible mesh circuit. The biochemical mouse brain completely accepted the mechanical component and integrated with it without any damage being caused to the mouse.

HONG KONG, Jan. 30 (UPI) — SpaceX and Tesla CEO Elon Musk said he plans to send humans to Mars by 2025.

Musk expressed his plans for the future of space travel at the StartmeupHK Festival in Hong Kong and said he plans to reach the International Space Station himself in four or five years.

“I don’t think it’s that hard, honestly,” he said. “It’s not that hard to float around.”

Over the last 12,000 years or so, human civilization has noticeably reshaped the Earth’s surface. But changes on our own planet will likely pale in comparison when humans settle on other celestial bodies. While many of the changes on Earth over the centuries have been related to food production, by way of agriculture, changes on other worlds will result, not only from the need for on-site production of food, but also for all other consumables, including air.

As vital as synthetic biology will be to the early piloted missions to Mars and voyages of exploration, it will become indispensable to establish a long-term human presence off-Earth, namely colonization. That’s because we’ve evolved over billions of years to thrive specifically in the environments provides by our home planet.

Our physiology is well-suited to Earth’s gravity and its oxygen-rich atmosphere. We also depend on Earth’s magnetic field to shield us from intense space radiation in the form of charged particles. In comparison, Mars currently has no magnetic field to trap particle radiation and an atmosphere that is so thin that any shielding against other types of space radiation is negligible compared with the protection that Earth’s atmosphere affords. At the Martian surface, atmospheric pressure never gets above 7 millibars. That’s like Earth at an altitude of about 27,000 m (89,000 ft), which is almost the edge of space. And it’s not like the moon is a better option for us since it has no atmosphere at all.

With a growing number of Earth-like exoplanets discovered in recent years, it is becoming increasingly frustrating that we can’t visit them. After all, our knowledge of the planets in our own solar system would be pretty limited if it weren’t for the space probes we’d sent to explore them.

The problem is that even the nearest stars are a very long way away, and enormous engineering efforts will be required to reach them on timescales that are relevant to us. But with research in areas such as nuclear fusion and nanotechnology advancing rapidly, we may not be as far away from constructing small, fast interstellar space probes as we think.

There’s a lot at stake. If we ever found evidence suggesting that life might exist on a planet orbiting a nearby star, we would most likely need to go there to get definitive proof and learn more about its underlying biochemistry and evolutionary history. This would require transporting sophisticated scientific instruments across interstellar space.

You might not know it, but you’re really just one Kickstarter away from launching your own satellite. CubeSats and other small, cheap spacecraft platforms have reduced the cost of getting to orbit by a huge margin, allowing for a more democratized age of space exploration.

As exciting as this populist spaceflight movement is, there is still one major technological hurdle it has to clear before it will meet its full potential: Propulsion.

Take CubeSats—cubic nanosatellites that typically weigh around three pounds. These modules are extremely popular with both professionals and hobbyists, and hundreds of them have been launched since 2003.
