Last year, a Made In Space-led team achieved something that had never been accomplished. For the first time in history, a commercial in-space manufacturing facility began operation aboard the International Space Station (ISS). While private parties are able to commission objects to be built by Made In Space’s Additive Manufacturing Facility (AMF) on orbit, the hardy device also supports astronauts by manufacturing parts, tools, and supplies that can be used on the ISS.
Made In Space has continued its mission to enable humans to live and work in space by demonstrating several new technologies in microgravity. Testing machines on Earth that are optimized to work in environments which have little or no gravity can be difficult at the bottom of Earth’s gravity well. The Flight Opportunities Program (FOP) at Johnson Space Center in Houston, Texas utilizes high-tech aircraft to fly in aggressive parabolic arcsa nose dive followed by a sharp ascent. This maneuver creates a gravity-free environment within the plane’s cabin for less than a minute before having to pull up and repeat. After partaking in over 200 of these parabolic flights, MIS has demonstrated several manufacturing techniques in microgravity that will be critical to the success of our journeys to other planets.
Who is responsible if a self-driving car crashes and causes property damages, physical harm or even death? Autonomous vehicle legislation is still very much in its infancy though it will certainly be an evolutionary process over the years. Corporations such as Tesla and Volvo have publicly stated that they will take responsibility for any faults in their software. However, Comma.ai’s CEO George Hotz (geohot) has stated that he is not responsible for any accidents caused by those who download his free self-driving vehicle software.
The idea of using robots as the go-to for handling disaster situations isn’t new, but part of the problem has been how to build robots light enough to move about easily, yet are strong enough and tough enough to handle things like a smashed up nuclear reactor. As part of the answer, the Tokyo Institute of Technology and Bridgestone Tires have partnered to develop a new hydraulic robotic muscle that is lightweight, yet is five to ten times as strong as conventional electric motors and much more durable.
The locations in disaster areas where the responders are needed most urgently are often the ones that are the hardest to get to, precisely because they’ve been hit so hard. The 2011 Fukushima nuclear disaster is a prime example. Despite the damage done to the nuclear power plant by the sea wave that struck it, the subsequent explosion and meltdown could have been avoided had emergency workers been able to reach it with the right equipment in time to make repairs and re-power the cooling systems.

For over 80 years, scientists all round the world have dreamt of converting hydrogen, the first element of the periodic table, into a metal. And now, after hundreds of failed attempts in the history, scientists from U.S. have finally managed the feat by compressing hydrogen so profoundly that it has turned into a metal!
Back in 1935, physicists Hillard Bell Huntington and Eugene Wigner proposed a theory that hydrogen, which normally exists in a gaseous state, could transform into metallic state once exposed to extreme pressure. Since then many scientists have tried to practically prove the theory — albeit unsuccessfully. However, this discovery, which was published in the journal ‘Science’ on Thursday, is the first confirmation of the theory.
The metallic hydrogen is a potential superconductor, a material with extraordinary electricity conducting capabilities, a quality which makes it a very expensive metal. But it holds the ability of revolutionizing the world of ultra fast super computers, high speed levitation trains, or any other thing which involves conduction of electricity.
On Wed we saw Tata’s new hydrogen bus; and now this.
DETROIT (Reuters) — General Motors Co and Honda Motor Co are expected on Monday to announce an expansion of their collaboration on fuel cell technology development, people familiar with the plans said following a notice of a press conference.
GM and Honda on Friday said two senior executives would hold a news conference in Detroit with Michigan’s Lieutenant Governor, Brian Calley.

The future of nuclear power might look very different than we thought, with a US-based company presenting plans for miniature, modular nuclear power plants that are so small, they can fit on the back of a truck.
NuScale Power, the company behind the power plants, says each modular device is completely self-contained, and capable of producing 50-megawatts of electricity — enough to power thousands of homes.
The power plants stand 29.7 metres tall, so aren’t really that ‘miniature’, except relative to an acutal nuclear power plant. They also haven’t been tested as yet, so we need to reserve our excitment for when we can actually see these things in action.
