Non-Rocket Spacelaunch – Space Elevators in Fiction
This is the fourth and final part of the space elevator article of the non-rocket spacelaunch methods article series. This post will focus on references to the space elevator concept in fiction. The first mention of anything remotely similar to a space elevator was the beanstalk in the children's fairy tale called Jack and the Beanstalk, published in 1807.
Non-Rocket Spacelaunch – Extraterrestrial Space Elevator Concepts
Space elevators, a futuristic concept, could be adapted for various celestial bodies: Mars, the Moon, and even asteroids, they promise a revolution in space access.
Non-Rocket Spacelaunch – Space Elevator Safety Issues
The space elevator is a gigantic concept and as such it has many safety issues that would have to be resolved before construction begins. A space elevator would present a navigational hazard, both to aircraft and spacecraft.
Non-Rocket Spacelaunch – Space Elevator
Why non-rocket spacelaunch? Because the current chemical rockets are really expensive. In order to further explore outer space and establish a permanent human presence in space we need more cost efficient spacelaunch methods.
An Artist’s Vision of a Future Colony on the Moon
Some time ago, I posted an image of the Copernicus Crater for the Astronomy Picture of the Week. Now I stumbled upon an amazing painting by Marshal T. Savage depicting his vision of a future colony on the Moon. It’s the same Copernicus Crater, except it’s domed over and terraformed to create an ecosphere. At first I thought that this was really cool, but it would be impossible to build such a gigantic structure. (The crater has a diameter of 93 kilometers!) However after giving it some thought I changed my mind. If it was built with a material strong enough like carbon nanotubes, it could in theory be built. While…
Astronomy Picture of the Week – The Copernicus Crater
Copernicus is one of the largest lunar impact craters on the visible hemisphere of the Moon. It was named after the Polish astronomer Nicolaus Copernicus. The crater is estimated to have formed about 800 million years ago during the Copernican period of lunar history, which was named after the crater. Copernicus is visible using binoculars, and is located slightly northwest of the center of the nearside, in eastern Oceanus Procellarum. The crater has a diameter of 93 kilometers and a maximum depth of 3.8 kilometers. Copernicus also has a dozen satellite craters ranging between 3 and 7 kilometers in diameter. By convention they share the name of the main crater…
Inflatable Space Stations
NASA is considering the use of inflatable modules for the International Space Station (ISS). This idea has been proposed as early as in the 1960s, but it has never been put to use in space until Bigelow Aerospace took over the idea and developed two working prototypes and tested them in space.
Dark Asteroids Discovered, Possible Threat to Earth
Dark asteroids near Earth, hard to spot but potential threats. WISE infrared telescope helps detect them. What's the risk of asteroid impact?
7 (Crazy) Civilian Uses for Nuclear Bombs
Nuclear Bombs are known to be the most destructive weapon man has ever created, but it could also be a great tool for some civilian uses. The 7 proposed civilian uses for some of the 23,000+ known nuclear bombs in the world are the following.
