The following is a huge infographic showing the true scale of the solar system with all its planets, minor bodies and the most famous probes we have sent out into deep space. Scientists measure distances in our solar system in astronomical units (AU).
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.
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?
Possibilities for Life on Mars
An article was recently published by Scientific American, a very reputable science magazine, stating that evidence was found that life existed on Mars and was brought to Earth on a meteorite. The meteorite in question is called "Allan Hills 84001". It was blasted from Mars by a huge meteorite impact 16 million years ago and crashed on Earth 13,000 years ago.
