Go Away, Gravity! – The Ventures of Elon Musk’s SpaceX and Richard Branson’s Virgin Galactic
Elon Musk has a net worth of $11.9 billion while Richard Branson has a net worth of $4.8 billion. If they stacked their respective fortunes in $1 bills atop each other, the tower would reach six million miles, almost 25 times the distance between the earth and the moon. And that is, in a metaphorical way, exactly what the two plan to do.
Evolution of the Space Suit [Infographic]
Two types of pressurized suits are in use today: "escape suits" worn inside the craft during launch and landing, and full "EVA" suits worn for working in the vacuum of space. NASA escape suits are colored International Orange for easy spotting by rescuers in the event of an emergency landing.
Could Space Junk Be a Threat to Our Hi-Tech Way of Life?
Space waste, space junk, orbital debris…whatever you call this orbiting mass of objects, they are a big issue. Space waste doesn't just make earth's orbital corridors look untidy, it poses a very real threat to the future of space exploration and our way of life. Read on to find out more…
Moscow’s Secret Moon Plan: The N-1 Rocket [Infographic]
“Hoping to beat the Americans to the moon before 1970, Soviet rocket engineer Sergey Korolyov worked in secret to plan the mighty N-1, an equal to the American Saturn V booster. In 1966 however, the sudden death of Korolyov threw Soviet plans into disarray. After four N-1s were lost in catastrophic accidents, the Soviets destroyed the remaining hardware and denied the very existence of the program. The N-1 remained a state secret until being made public in 1990.” Taken from the infographic below: Source Space.com: All about our solar system, outer space and exploration
Antimatter Discovered Around Earth
A ring of antimatter, more specifically antiprotons, has been recently discovered around the Earth. Since antiprotons are charged sub-atomic particles, they are confined by the planet's magnetic field lines.

Non-Rocket Spacelaunch – Advantages and Difficulties of a Launch Loop
Unlike conventional rockets, launch loops can have many launches per hour, independent of weather, and are not inherently polluting. Rockets create pollution such as nitrates in their exhausts due to high exhaust temperature, and can also create greenhouse gases depending on propellant choices. Launch loops require power in the form of electricity and as such it can be clean.
Non-Rocket Spacelaunch – Launch Loop
A launch loop (also known as a Lofstrom loop) is a proposed design for a very efficient non-rocket spacelaunch method. It is a much simpler concept than the space elevator, but still more complex than tether propulsion systems such as the rotovator.
Non-Rocket Spacelaunch – Tether propulsion in fiction
This is the fourth and final part of the tether propulsion article of the non-rocket spacelaunch methods article series. This post will focus on references to the tether propulsion concept in fiction. The most prominent science fiction novels on the subject include the following.
Non-Rocket Spacelaunch – Tether propulsion safety issues
The use of tethers in space poses many challenges and safety issues. This third part to the tether propulsion article will focus on those issues. A lot of the challenges and safety issues of a space tether system are similar to those of a space elevator described in a previous article, but some are unique to the space tether concept.
Non-Rocket Spacelaunch – Tether satellite missions
This is the second part to the article about tether propulsion. It will focus on space missions that tested tethers in space. The first such mission took place in 1966. Gemini 11 deployed a 30m tether connecting it to the Agena target vehicle. It created a small amount of artificial gravity (0.00015 g) by spinning the two spacecraft.
Non-Rocket Spacelaunch – Tether propulsion
Tether propulsion consists in using long, very strong cables (known as tethers) to change the velocity of spacecraft and payloads. The tethers may be used to initiate launch, complete launch, or alter the orbit of a spacecraft. This form of propulsion would be significantly less expensive than spaceflight using modern rocket engines.
