Just like checking your bag on a commercial airline, space travel comes with some pretty big weight restrictions. How big? According to estimates, reaching space costs a whopping $10,000 per pound, which means that every ounce saved has a big impact on the bottom line.

That’s where a group of Danish researchers comes in. The team is working on a synthetic biology project called CosmoCrops, which hopes to use bacteria to make it possible to 3D print everything needed for a respectable space mission, using a cutting-edge co-culturing system. And it could even make life better for those of us back on Earth in the process.

“We are trying to make space exploration cheaper, because many inventions we use in our daily life were invented because of space exploration, like Velcro and solar energy,” Joachim Larsen, one of the students working on the project, told Digital Trends. “The way we want to achieve this is to [be] able to produce everything from food to medicine and bioplastic for 3D printers out in space — making the space rocket a lot lighter.”

Is building our own starship Enterprise possible? Will we ever travel between the stars as easily as they do in Star Trek? JJ Abrams’ new feature, Star Trek Into Darkness, hits the screen in a golden age of scientific discoveries. HISTORY is there, giving viewers a deep look behind the scenes, on the set, and into the science–amazing new exoplanets, the physics of Warp drive, and the ideas behind how we might one day live in a Star Trek Universe.

The Estes Park Advanced Propulsion Workshop, 20–22 September 2016, organized by the Space Studies Institute (SSI), will feature presentations by NASA Eagleworks scientist Paul March and Prof. Martin Tajmar, chair for Space Systems at the Dresden University of Technology, who last year presented an independent confirmation of the anomalous EmDrive thrust.

Other notable participants include Prof. James Woodward and Prof. Heidi Fearn, both from California State University, Fullerton, and Prof. David Hyland from Texas A and M University.

The 3-day conference will address at most 6 concepts for a breakthrough in propulsion. They are devoting a half-day per concept. The half-day is broken into theory and experiment sessions for the concept. The concept will be investigated on both grounds, with substantial give-and-take between the audience and the concept presenter, verbally and on the whiteboard.

Theory of a mach effect thruster I

The Mach Effect Thruster (MET) is a propellant—less space drive which uses Mach’s principle to produce thrust in an accelerating material which is undergoing mass—energy fluctuations. Mach’s principle is a statement that the inertia of a body is the result of the gravitational interaction of the body with the rest of the mass-energy in the universe. The MET device uses electric power of 100 — 200 Watts to operate. The thrust produced by these devices, at the present time, are small on the order of a few micro-Newtons. Researchers give a physical description of the MET device and apparatus for measuring thrusts. Next they explain the basic theory behind the device which involves gravitation and advanced waves to incorporate instantaneous action at a distance. The advanced wave concept is a means to conserve momentum of the system with the universe. There is no momentun violation in this theory. We briefly review absorber theory by summarizing Dirac, Wheeler-Feynman and Hoyle-Narlikar (HN). They show how Woodward’s mass fluctuation formula can be derived from first principles using the HN-theory which is a fully Machian version of Einstein’s relativity. HN-theory reduces to Einstein’s field equations in the limit of smooth fluid distribution of matter and a simple coordinate transformation.

It is shown that if Mach’s Principle is taken seriously, and the inertia of a body can be described as the interaction of the body with the rest of the universe, then the advanced and retarded fields transmitted between the particle and the universe can be used to explain the thrust observed in the Mach Effect drive experiments. This idea was originally put forward by one of the authors, James Woodward. The idea of inertia being a gravitational effect was first postulated by Einstein. In fact Mach’s principle was the foundation on which Einstein’s general relativity was based.

Want to immigrate? Why not to Russian Space Settlement.

Roscosmos has revealed plans to send a manned mission to the moon between 2025 and 2045 – some 60 years after Neil Armstrong’s Apollo mission ended the space race between the US and Soviet Russia.

Russian Academy of Cosmonautics member Yury Karash previously said: “Back in the 1960s the Soviet Union was competing head-to-head with the United States.

“But it is hard to find a better way to hurt Russian prestige and emphasise Russian technological backwardness than by sending cosmonauts to the Moon around 2030, 60 years after Apollo.”

Clay Wang brought his kids to the California Space Center a few years ago to show them the Space Shuttle. But as he looked up at Endeavour and pondered human space exploration, the pharmacologist wondered, “What if a crew runs out of medicine halfway to Mars?”

A lot of things can go wrong during a three-year mission to Mars, and there’s only so much medicine you can pack. “For food you can predict exactly how much the astronauts will need to eat,” says Wang. “Medicine you can’t predict.”

What if they develop a sudden need for a drug that wasn’t packed? Compounding the problem is the fact that the space environment seems to make many drugs lose potency and degrade more quickly compared to drugs on Earth.

Scientists have shown they can teleport matter across a city, a development that has been hailed as “a technological breakthrough”.

However, do not expect to see something akin to the Star Trek crew beaming from the planet’s surface to the Starship Enterprise.

Instead, in the two studies, published today in Nature Photonics, separate research groups have used quantum teleportation to send photons to new locations using fibre-optic communications networks in the cities of Hefei in China and Calgary in Canada.
