Seen from space, cities look incredibly detailed at night, when streetlights and buildings glow brightly enough that it’s possible for astronauts to clearly see individual streets. Photos taken from the International Space Station inspired London-based animator Marc Khachfe to spend hours creating this artwork in homage.
Chris Hadfield is a hero. A boss. The real deal. Not simply because he was Commander of the International Space Station, but for what he did while up there. Not content with being just “an astronaut,” he assumed the role of rock-star spaceman, conducting regular science-experiment videos from space, answering questions like, “What happens to tears in space?” Then, he gave us this: the first video from space. Watching Hadfield’s rendition of David Bowie’s “Space Oddity” while orbiting the Earth is nothing short of sublime. Mr. Hadfield, you win 2013.
The Towed Glider Air-Launch is an experimental project (still awaiting government approval) that would fire air-launching rocket boosters from a drone glider. In Budd’s modest words, the proposal offers “affordable, flexible access to space.” A glider would be towed into high altitudes by military transport aircraft on planned flights and would be released by the plane—the glider would then fire a rocket booster (with a satellite enclosed) into orbit. Afterward, pilots located in remote NASA facilities safely guide the glider home.
When a star like our sun uses up all of the hydrogen in its core, it becomes what is called a “planetary nebula.” The star sheds its outer layers of gas, leaving behind a hot core.
This composite image of NGC 2392 includes data from NASA’s Chandra Space Telescope, showing the location of million-degree gas near the center of the planetary nebula in pink. Readings from the Hubble Space Telescope - colored red, green, and blue - show the intricate pattern of the outer layers of the star that have been ejected.
On this day in 1958, the United States Congress passed legislation creating the National Aeronautics and Space Administration (NASA). Since its creation, NASA has played a vital role in coordinating all of the US’ activity in space. The agency spearheads and sponsors space exhibitions and has launched numerous orbiting satellites that have produced information about the solar system and universe.
In recent years, many feel that NASA has experienced numerous setbacks. The most significant being the end of the space shuttle program in 2011.
Planetary Resources, the innovative, bold company with plans to strip-mine asteroids for their valuable resources, has revealed it will use advanced 3-D printing techniques to produce its line of Arkyd space telescopes.
And NASA just successfully test-fired a rocket engine that uses a 3-D printed injector component. The advantage of 3-D printing this part is the speed and precision of the process, which NASA notes would otherwise have required a year of careful machining to make. It doesn’t hurt that it also cost 70% less to produce…
