These are the postcards people will send home from their interplanetary vacations in 500 years. For now we can only gather them with robots, space stations and satellites. Still, it's pretty awesome to be living in a time when we can do even that. A gallery of sublime photographs from across our solar system
These incredible photos from the International Space Station make Earth look like a video game That general glow you're seeing from Earth is actually a naturally occurring phenomenon called "airglow". Airglow is unrelated to human activity, and is the result of excitement of atoms in the atmosphere, leading to light emission. Airglow is responsible for a large majority of the nighttime light (moonless night) and is estimated as providing almost 10x as much light as background stars.

NASA develops 3D printing factory in space News: NASA is developing an orbiting factory that will use 3D printing and robots to fabricate giant structures such as antennas and solar arrays of up to a kilometre in length, as part of its ongoing search for extra-terrestrial life. The US space agency this week announced it was awarding technology firm Tethers Unlimited Inc (TUI) a $500,000 contract to develop the facility. The NASA funding - a second-phase contract that follows an initial contract issued earlier this year - will allow TUI to continue work on its SpiderFab technology, which allows large-scale spacecraft components to be built in space, avoiding the expense of building the components on earth and transporting them into space using rockets. “On-orbit fabrication allows the material for these critical components to be launched in a very compact and durable form, such as spools of fiber or blocks of polymer, so they can fit into a smaller, less expensive launch vehicle.”
Space is a place for finished products. The satellites we send into orbit are checked, rechecked and then triple checked to make sure that nothing will fail. That finished product is then neatly folded, packed away atop a giant rocket, and blasted off into orbit. But one company in the US, recently awarded $500,000 (£320,000) by Nasa, wants to change this paradigm. Nasa-backed space spider concept to build giant satellites in orbit
