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.

In a new interview, Elon Musk identifies genetics, AI, and brain bandwidth as three areas in which today’s youth can have the biggest impact on the future. However, he doesn’t think an idea needs to be revolutionary to be worthwhile.

While many 2o-something-year-olds are just finding their way in the world, young Elon Musk was already looking for ways to change it way back in 1995 (when he was that age).

In a well-known 2015 discussion with Neil deGrasse Tyson for the physicist’s StarTalk Radio podcast, Musk lists the five things he thought would most affect the future of humanity (the internet, sustainable energy, space exploration, artificial intelligence, and rewriting human genetics).

Tiangong translates literally to ‘Heavenly Palace’ and is China’s first space station program which, in its early stages, is not unlike the early Salyut space stations and the American Skylab – launched with equipment and supplies for a finite mission duration already on board and not serviced by cargo resupply vehicles.

China’s first Heavenly Palace arrived in orbit in late September 2011 after a flawless launch atop a Long March 2F rocket. Orbiting Earth over 300 Kilometers in altitude, Tiangong was first visited two months after launch when the uncrewed Shenzhou-8 spacecraft completed China’s first automatic docking in space.

A look at the concept of Self-Replicating Machines, Universal Assemblers, von Neumann Probes, Grey Goo, and Berserkers. While we will discuss the basic concept and some on-Earth applications like Medical Nanotechnology our focus will be on space exploration and colonization aspects.
